Description

technical field [0001] The present invention relates to devices in the field of mechatronic engineering, in particular to testing devices. Background technique [0002] With the rapid development of electronic technology and the miniaturization of electronic equipment and electronic components, the volume power density of equipment is increasing, resulting in the continuous increase of heat dissipation power of equipment, especially in vehicle electronic equipment. If the heat dissipation of the electronic device cannot be dissipated in time, it will have a great impact on the performance of the electronic device, and even cause destructive damage, making the entire device invalid. Among the common failures of electronic equipment, as high as 50% to 60% of the equipment cannot work normally due to the high temperature of the electronic equipment. Therefore, it is particularly important to develop an efficient and reliable heat dissipation element, that is, an electronic col...

AI Technical Summary

Problems solved by technology

[0004] Existing cold plate test devices are simple systems temporarily built on the test bench for a certain cold plate. The water pump is a single-stage centrifugal pump, resulting in a small measurement range. With the same heat flux density, the thermal insulation measures for the heat source on the surface of the cold plate to dissipate heat to the surrounding environment are not good enough. At the same time, due to the uneven thickness of the heat-conducting silica gel applied between the cold plate and the heating resistor module, the measurement error is large and the filter accuracy is low. Poor cleanliness in the system affects measurement accuracy
