[0031] Working principle:

[0032] like Figures 1-5As shown, when a product needs to be tested, the door 12 is opened, and the storage space formed by the door 12, side panel 11, and its upper and lower sides, top panel 13, lower side panel 14, and support plate 15 is placed inside. The required climate parameters for testing are set through the electronic control display screen 4. The motor 21 is started according to the temperature requirements. The motor 21 rotates the cooling or heating surface of the semiconductor cooling chip 25 towards the storage space via the connecting rod 23 according to the cooling or heating requirements, until the semiconductor cooling chip 25 is flush with the outer support plate 15, and then stops. When heating or cooling the ambient temperature of the space where the test product is located, the cooling fan 2, which is symmetrically arranged inside the fan frame 27 fixedly connected to one side of the support plate 15 and the inner side of the back plate 17, is used. The operation of fan 6 and cooling fan 28 accelerates the airflow speed of the thermoelectric cooler 25 toward the back plate 17, thereby quickly blowing out the residual heat and cold of the thermoelectric cooler 25 from the ventilation holes set on the side plate 11 near the back plate 17, maintaining the temperature difference on both sides of the thermoelectric cooler 25, and ensuring cooling and heating efficiency.

The pumped water is sprayed into the detection environment of the item through the pipe of the water outlet pipe 34 and the atomizing nozzle 35 which is fixedly connected to the water outlet pipe 34, thereby adjusting the humidity of the detection environment and realizing the function of adjusting the aging resistance testing equipment to multiple climates.
