Problems solved by technology

[0003] Existing resistance heat resistance detection devices used in high-temperature areas of electronic equipment usually place the resistance to be tested in a detection box when testing, and pass high-temperature gas into the detection box to make the resistance in a high-temperature environment , and put the resistor in the detection circuit by introducing the circuit, and judge the heat resistance performance of the resistor by detecting the indicators of the resistor in the high temperature environment. However, when the electronic equipment used in the high temperature area is actually used, there is a high temperature environment. Immediately shut down the fast cooling zone, and restart after cooling for a certain period of time, there is an alternating situation of high and low ambient temperature, and the alternating switching of high and low temperature environments has a great impact on the service life of the resistor. Carrying out continuous performance testing, it is impossible to effectively complete the heat resistance performance testing in a small alternating environm
