Problems solved by technology
Frosting in the cabin not only affects the cooling efficiency of the low-temperature test chamber, but may also affect other devices in the test chamber
In order to eliminate the impact of frosting, most users stop the operation of the equipment for defrosting once excessive frosting occurs, so that the utilization rate of the equipment is forced to decrease, and at the same time, it may disrupt the rhythm of upstream or downstream processes

The invention discloses a frostless low temperature test chamber which comprises a low temperature test chamber body, an air drier, a pressure flow controller, a cabin door inductive switch, an air curtain, a controller, a gas stop valve and an air deflector, wherein the air drier is connected with the pressure flow controller; the pressure flow controller and the low temperature test chamber body are connected with the gas stop valve; the gas stop valve and the cabin door inductive switch are both connected with the controller; the gas stop valve is connected with the air curtain; and the air curtain and the air deflector are respectively positioned above and below the low temperature test chamber body. The frosting phenomenon is guaranteed not to occur in a cabin when a cabin door is opened frequently during the test process.
Description
technical field [0001] The invention relates to a frost-free low-temperature test chamber, in particular to a low-temperature test chamber which requires continuous work and opens a cabin door to pick and place test objects during the working process. Background technique [0002] At present, most of the known low-temperature test chambers do not open the hatch door frequently during the sample process. Once the hatch door needs to be opened frequently, the phenomenon of frosting in the low-temperature environment will occur due to the water-containing air in the environment entering the cabin. Frosting in the chamber not only affects the cooling efficiency of the low-temperature test chamber, but may also affect other devices in the test chamber. In order to eliminate the impact of frosting, most users stop the operation of the equipment for defrosting once excessive frosting occurs, so that the utilization rate of the equipment is forced to decrease, and at the same time, ...
