DESCRIPTION OF EMBODIMENT

[0013] The embodiment of the present invention with reference to the drawings described in details as below.

[0014] FIG. 1 illustrates heating radiator HRZTECH unit 15 according to the embodiment, heating radiator HRZTECH unit 15 works for any fluid heating system. As shown in FIG. 1 according to the embodiment, a diagram illustrating the heating source 1 connected to the heating radiator HRZTECH 15 as well as to other heating units 11, and the flow between the heating source 1 and the heating load runs in a closed circuit 13.

[0015] The schematic drawing in FIG. 2 shows the heating radiator HRZTECH unit 15 according to the embodiment, the lower tank 2 receives hot fluid from the heating source 1 by means of a circulation pump (not shown) through the inlet line 16. The fluid, for example water, in the primary heating circuit 18 circulates from the heating source 1 toward a temperature regulating valve 12 toward the lower tank 2 inlet 2a, and the fluid inside the primary heating circuit 18 returns 17 to the heating source 1 from the lower tank 2 outlet 2b. When the temperature of the fluid inside the primary heating circuit 18 reaches the set temperature of the heating source 1 it will tums-off automatically, whereas the hot fluid inside the primary heating circuit 18 remains circulating inside by means of a circulation pump (not shown). [0016] A set of heat pipes 6 mounted on the upper surface of the lower tank 2 penetrating the chambers 9. The fluid inside the primary heating circuit 18 starts to heat up the lower tank 2, and thereby the lower tank 2 starts to transfer the heat to the lower segment 9 of the heat pipes 6. The fluid inside the heat pipes 6, for example water, receives the heat at the lower segment 9 of the heat pipes 6 from the lower tank 2. The fluid inside the heat pipes 6, for example water, starts to boil and change phase generating hot steam inside the heat pipes 6, and this stage called intermediate heating stage 19. The intermediate heating stage 19 inside the heat pipes 6 allow the steam to rise upward towards the upper segment 10 of the heat pipes 6, and the upper segment of the heat pipes becomes hot. The fluid inside the heat pipes 6 boiling temperature can be 30 °C since the water inside the heat pipes 6 is under vacuum. According to the embodiment, the generated steam as a working fluid has a temperature of 100°C or below. According to the embodiment, the liquid phase and the generated steam inside the heat pipes 6 as a working fluid has a temperature range 30 °C to 100 °C. The upper segment of the heat pipes 6 penetrates the lower surface of the upper tank 3 chambers 10.

[0017] The upper tank 3 receives the heat from the heat pipes 6, then the upper tank 3 transfers the heat to another cold heat fluid inside, for example diluted ethylene glycol, the upper tank 3 allows the inside fluid temperature to rise, and this stage is called the secondary heating stage 3c, while the steam inside the heat pipes 6 in the intermediate heating stage 19 starts to condense flowing downwards toward the lower segment of the heat pipes 6, and this process is a continuous sustainable cycle. When the fluid temperature rises inside the upper tank 3, it starts to expand in volume; this expansion in addition to the gravitational effect will force the heated fluid to flow downward via the side panels jackets 4 towards the side reservoirs 5, also the expanded fluid volume forces the fluid inside the side reservoirs 5 to flow via the outlets 5a and 5b located at the side reservoirs 5, then fluid flows upward via side pipes 20, each side pipe 20 is provided with a regulating valve 7 to control flow, and a single direction valve 8 for keeping the flow between the side reservoirs 5 and the upper tank 3 to flow in one direction, the fluid enters the upper tank 3 from the two inlet orifices 3a and 3b. This cycle is called the secondary heating stage 3c, and the fluid remains in circulation until reaching the required surrounding environment temperature.

[0018] When the surrounding environment temperature is reached, the temperature regulating valve 12 closes the flow from the primary heating circuit 18, while the fluid inside the secondary heating cycle 3c remains in circulation. Also, the fluid in the intermediate heating stage 19 inside the heat pipes 6 continues to change phases from liquid to steam and vice versa. At the same time the side panels jackets 4 with the upper tank 3 radiates the heat to the surrounding environment.

[0019] When the surrounding environment temperature decreases below the set temperature of the temperature regulating valve 12, the regulating valve 12 open again allowing the intermediate heating cycle 19 via the heat pipes 6 to increases the temperature in order to heat the fluid inside the upper tank 3 which in turn feeds the hot fluid to the side panels jackets 4 and radiate the heat to the surrounding environment.

[0020] Depending upon the number of heating units used for heating purposes, if the temperature of the heating source 1 decreases below the set heating source 1 temperature, then the heating source 1 turns on again to increase the temperature of fluid fed to the heating units allowing the temperature regulating valve 12 to open, so that the lower tank 2 receives the hot fluid. By these means, the three heating stages (the primary 18, the intermediate 19 and the secondary 3c) may work at the same time or independently without affecting the heating cycle process. [0021] According to the embodiment as described earlier for heating radiator HRZTECH unit 15, the upper tank top surface is provided with two orifices 22, one is used for filling the liquid and the other is used for bleeding purposes, the components configured in such a way that the heat pipes 6 fitted between the lower tank 2 and the upper tank 3, where the side panels jackets 4 and the side reservoirs 5 are connected to the upper tank 3 only, also, the side reservoirs 5 located above the lower tank 2 having a certain spacing between them.

[0022] The material of the lower tank 2, upper tank 3, the side panels jackets 4, the side reservoirs 5, and the frame casing 21 are made of steel, or steel alloy, while the heat pipes 6 material are made from copper or copper alloy. The heat pips 6 volumetric thermal expansion is higher than all other parts in the heating radiator HRZTECH vertical thermal expansion, thus suitable tolerances are considered in upper chambers 10 and the lower champers 9 located at the upper tank 3 and lower tank 2 to adopt the heat pipes 6 thermal expansion.

[0023] Heating radiator HRZTECH unit 15, according to the embodiment, provided with a set of heat pipes 6, the temperature range of the fluid inside the upper tank 3 e.g., in the range of 40 to 50 °C or below.

[0024] The heating radiator HRZTECH unit 15 can be expanded with plural numbers of heat pipes 6 without any additional changes in the size of heating radiator HRZTECH unit 15, where additional empty chambers are available in both the lower tank 2 upper surface and the upper tank 3 bottom surface to accommodate additional plural sets of heat pips 6 in order to accommodate the increasing heating load requirements for several surrounding environment areas. When heating radiator HRZTECH unit 15 is provided with plural number of heat pipes, the temperature of the fluid in the upper tank 3 will have a temperature range of 40 to 65 °C or below, hence it leads to an increase in the fluid temperature inside the upper tank 3 at a faster rate, consequently the flow regulating valve 7 is capable to control a higher flowrate of the fluid to the upper tank 3 and the side panels jackets 4 flowing towards the side reservoirs 5, and keeping the fluid temperature within the required setting range.

[0025] The lower tank 2 and the middle segments of the heat pipes 6 are covered with an insulator 14 to reduce heat dissipation.

[0026] The present invention is not limited to the above embodiment, and hence, various changes and modifications and the like can be expected without departing from the scope of the present invention. For example, the embodiment shows heating radiator HRZTECH unit 15 used for heating purposes, but the present invention is not limited to this example. For example, heating radiator HRZTECH unit 15 may be configured, for example, as a special heating unit in certain process.

[0027] In addition, in the embodiment, the heat pipes 6 arranged in a parallel column set, but the present invent is not limited to this, heating radiator HRZTECH unit 15 may have up to 3 sets columns of heat pipes 6 without any additional modifications or changes in its size or.

[0028] An outline of the above embodiment is described as below.

[0029] Heating radiator HRZTECH unit according the above-mentioned embodiment configured in such a way that the heat received from the heating source is converted to a higher heat range produced by the heat pipes. Hence, there is no need to increase the temperature of the fluid flowing from the heating source to compensate for a higher temperature requirement by a consumer, or any losses occurred in the heating load circuit piping system, whereas the heating radiator HRZTECH unit can resolve and meet these requirements in a clean sustainable process. [0030] The fluid from the heating source passes through the lower tank at a relatively lower fluid temperature i.e. 35 °C comparing to the existing heating radiators used for heating purposes, the fluid passing through the lower tank rises the material temperature while in circulation between the heating source and the lower tank of the heating radiator HRZTECH unit, when the temperature from the heating source reaches its set temperature, the heating source turns off automatically, and the fluid inside the primary heating circuit between the heating source and the lower tank remains in circulation. When the temperature of the fluid inside the heating source circuit decreases below the set temperature of the heating source, the heating source turns on automatically to start heating the fluid inside the primary heating cycle, and this stage called the primary heating stage.

[0031] The lower tank transfers the heat to the lower segment of the heat pipes placed at certain positions without contacting the fluid received from the heating source, then, another fluid inside the heat pipes starts to boil depending upon the heat pipes specifications and the fluid used inside, this stage called the intermediate heating stage. According to the embodiment, the fluid inside the heat pipes temperature starts rises to the boiling temperature, and the generated steam inside the heat pipe which rises upward reaching the upper segment of the heat pipes.

[0032] Hereafter, the upper part of the heat pipes transfers the heat to the upper tank material through direct contact, and without contacting the fluid inside the upper tank. Hence, the upper tank material temperature starts to increase, and the heat is transferred to the fluid inside the upper tank allowing the fluid temperature increase too. When the temperature of the fluid inside the upper tank rises, the fluid expands in volume forcing the fluid to flow downwards through the side panels jackets towards the side reservoirs allowing the fluid to radiate the heat from the jacket surfaces, then the low temperature fluid return to the upper tank for gaining heat again, and it is called the secondary heating stage.

[0033] This cycle remains in a continuity until the temperature of the fluid circulating between the heating source and the lower tank decreases below the set temperature of the heating source. At this stage a temperature control valve closes the flow to the lower tank, and the heating source starts up automatically to heat the fluid in the primary heating circuit. Then, when fluid in the primary heating cycle reaches the set temperature of the temperature control valve, it opens the flow towards the lower tank inlet, and so on the three heating stages continues.

[0034] According to the embodiment for the present invention, the primary heating stage with the intermediate heating stage and the secondary heating stage represents heating radiator HRZTECH unit heating stages.

[0035] In addition, according the above-mentioned aspects in the embodiment for this invention, heating radiator HRZTECH unit is capable in increasing heating efficiency by rising the temperature in a sustainable process without using any additional energy, as well as the heating radiator HRZTECH unit assists in reducing the temperature from the existing heating source to a lower level, which in turn reduces energy consumption leading to minimize the GHG emitted.
