Abstract

The invention provides a heat dissipation performance test system. A power supply unit is in circuit connected with a heating device to form a loop, the heating device is arranged on the tested water-cooling heat sink, a water supply unit is in waterway connection with the tested water-cooling heat sink to form another loop, and a control unit controls switches of the power supply unit and the water supply unit respectively through an industrial personal computer. In the waterway loop of the water supply unit and the tested water-cooling heat sink, a pipeline of a water inlet end of the tested water-cooling heat sink is provided with a flow controller, a pressure sensor and a temperature sensor. A pipeline of a water outlet end of the tested water-cooling heat sink is provided with the temperature sensors. The water inlet end and the water outlet end of the tested water-cooling heat sink are in parallel connection with a bypass which is provided with a differential pressure sensor. Compared with the prior art, the heat dissipation performance test system and method are capable of rapidly and accurately measuring heat dissipation performance of the tested water-cooling heat sink.

Description

technical field [0001] The invention relates to a heat dissipation performance test system of a radiator, in particular to a heat dissipation performance test system of a water-cooled radiator and a test method thereof. Background technique [0002] As my country's high-voltage direct current transmission technology becomes increasingly mature, the construction of direct current transmission projects is in a golden period of development. In the high-voltage direct current transmission system, the cooling system is an important component of the heat dissipation system of the converter valve, and its operation directly affects the power transmission capacity of the entire direct current system. Therefore, it is particularly important to ensure the stable, reliable and efficient operation of the cooling system. [0003] With the rapid development of power electronic technology, power electronic devices tend to be more and more large-capacity and micro-integrated, leading to th...
