Heat radiator test system and test method

Abstract

The invention discloses a heat radiator test system and a test method, which relate to the technical field of heat radiator detection, and comprises an oil tank, an oil inlet pipe, an oil return pipe,a water tank, a water inlet pipe, a water outlet pipe, a test board and at least one heat radiator fixing part. A heat radiator is fixed onto the heat radiator fixing part; the oil tank is connectedwith one end of the heat radiator through the oil inlet pipe; a heater is arranged on one end, close to the oil tank, of the oil inlet pipe; an inlet temperature sensor is arranged on one end, close to the heat radiator, of the oil inlet pipe; the oil tank is connected with the other end of the heat radiator through the oil return pipe; an outlet temperature sensor is arranged on the oil return pipe; the water tank is connected with one end of the heat radiator through the water inlet pipe, and is connected with the other end of the heat radiator through the water outlet pipe. According to theheat radiator test system provided by the invention, a comparison test can be conveniently carried out, a test result is accurate and reliable, a test process can be intuitively observed at the sametime, and a ceaseless loop test is carried out. The heat radiator test method provided by the invention is simple in test steps, and remarkable in comparison effect.

Description

technical field [0001] The invention relates to the technical field of radiator detection, in particular to a radiator testing system and testing method. Background technique [0002] At present, the heat sink design of power devices has become an increasingly important part of industrial design; with the increase of power level, the air cooling heat dissipation method has been difficult to meet the industrial needs, and the liquid cooling heat dissipation has become the mainstream heat dissipation method of high-power heat sinks , the preliminary design of liquid-cooled radiators is usually carried out using thermal simulation software; however, due to the large differences between the simulation environment and the actual use environment, designers often need to compare the heat dissipation effect of the improved liquid-cooled radiator At present, there is no test device for measuring the characteristics of liquid-cooled heat dissipation devices. [0003] As disclosed in ...
