Description

technical field [0001] The invention relates to a desktop air-to-air plate-fin heat exchanger performance test device, in particular to a desktop air-to-air plate-fin heat exchanger performance test experimental device based on a semiconductor heat pump. Background technique [0002] At present, the limited area of ​​laboratories and the aging of equipment are common phenomena in colleges and universities. Even if the laboratories are recycled and public arrangements are becoming very crowded, the arrangement of experimental benches has become a luxury. [0003] At present, the air-to-air heat exchanger performance test device uses electric heating, which consumes a lot of energy; and the hot air is directly evacuated, causing serious heat pollution and heat waste, low efficiency, and not environmentally friendly. [0004] The semiconductor heat pump can realize high-efficiency heating, small size, low noise, no mechanical moving parts, and simple and convenient control. C...
