Frostless high and low temperature testing machine
PendingCN113600253ANo frostWide range of testsHeating or cooling apparatusEnclosures/chambersControl systemEngineering
The invention relates to a frostless high and low temperature testing machine which comprises a box body, a testing cabin arranged in the box body, a first cavity connected with the testing cabin, a refrigerating device and a control system. The testing cabin is communicated with the first cavity through an air inlet and an air outlet, and the frostless high and low temperature testing machine further comprises a drying device, a heating device and a circulating fan. The observation window is provided with at least one operation port. According to the frostless high and low temperature testing machine, the testing temperature range is -82 DEG C to 180 DEG C, the testing range is wide, long-time operation can be kept at the low temperature, through the adoption of the box body structure and the drying device, even if the temperature is as low as -82 DEG C and the observation window is large in size, it can still be ensured that the testing chamber and the observation window cannot be frosted, and the aging test requirements on products in the high-precision industrial field are met.
