Title:
UNIFORM TEMPERATURE HEAT-CONDUCTIVE PIPE
Document Type and Number:
WIPO Patent Application WO/2010/083644
Kind Code:
A1
Abstract:
A uniform temperature heat-conductive pipe comprises a main water pipe (1), a front auxiliary pipe (2), a rear auxiliary pipe (3) and a valve (4). One end of the main water pipe (1) and one end of the front auxiliary pipe (2) are connected to a hot water source respectively. The other end of the main water pipe (1) and one end of the rear auxiliary pipe (3) are connected to each other to form a connection section (5). The valve (4) is set at the connection section (5). An inner circulation drive device is set between the front auxiliary pipe (2) and the rear auxiliary pipe (3). When the valve (4) is closed, the inner circulation drive device makes the water in the front auxiliary pipe (2) and in the rear auxiliary pipe (3) flow towards the connection section (5), and makes the water in the main water pipe (1) flow towards the hot water source. When the valve (4) is open, the inner circulation drive device makes the water in the main water pipe (1), in the front auxiliary pipe (2) and in the rear auxiliary pipe (3) flow towards the valve (4). The water in the pipe between the hot water source and the valve (4) can circulate with the hot water source. When the valve (4) is open, hot water can flow out.
