Description
【Technical Field】 [0001] The present invention relates to a calibration device, in particular to a calibration device for thermal resistance testing equipment. 【Background technique】 [0002] At present, the thermal resistance test equipment, especially the thermal resistance test equipment of electronic product radiators, still lacks a precise device in the industry for the verification of the equipment itself. It can only be done simply between the various test machines with a general heat sink. To reduce the test error between test units, this method has the following disadvantages: [0003] 1. Changes in the test environment such as ambient temperature, humidity, and the thermal power of the test machine through the contact interface cause the test comparison data to be inaccurate; [0004] 2. The test equipment has not been verified by a unified standard, and the test data lacks versatility. Therefore, the measured data can only be used for comparison and cannot represent th...
