Title:
APPARATUS FOR MEASURING HEAT DISSIPATION OF LIQUID-COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/036652
Kind Code:
A1
Abstract:
An apparatus for measuring the heat dissipation of a liquid-cooling device, the apparatus comprising: a cavity (1), which is used for placing a liquid-cooling device (200), wherein the cavity (1) is provided with an air inlet and an air outlet; a data collection module, which comprises temperature sensors (17, 18) and a flow sensor, wherein the temperature sensors (17, 18) measure temperatures at the surface of the liquid-cooling device (200), the air inlet and the air outlet, and the flow sensor measures mass flow rates at the air inlet and the air outlet; and a heat dissipation calculation module, which determines the heat dissipation rate of the liquid-cooling device (200) according to the specific heat capacity of air, the mass flow rate at the air outlet, and the difference between the temperatures of air at the air inlet and the air outlet. By means of placing a liquid-cooling device (200) in a cavity (1), the apparatus can determine the heat dissipation of the liquid-cooling device (200) by means of measuring heat absorbed by air that passes through the cavity (1), which heat is dissipated by the liquid-cooling device (200); and according to whether the average surface temperature of the liquid-cooling device (200) when operating without being placed in the cavity (1) is obtained in advance, sensor data can be obtained by using different measurement methods, so as to respectively obtain the heat dissipation of the liquid cooling device (200).
