Abstract

The invention discloses a gas cooling device for a vacuum drying box. The gas cooling device comprises a shell, and an expansion type cooling mechanism and a drying chamber which are communicated in sequence are arranged in the shell; and the shell is provided with an air inlet and an air outlet, the air inlet is in communication with the expansion type cooling mechanism, and the air outlet is incommunication with the drying chamber. The invention further discloses a vacuum drying box. The drying box comprises a box body, a working chamber arranged in the box body, a vacuum pump communicatedwith the working chamber and two gas cooling devices used for the vacuum drying box, and when the interior of the first gas cooling device is in the pressure reduction and temperature reduction stroke, the interior of the second gas cooling device is in an exhaust reset stroke, and the working states of the two gas cooling devices are alternately changed. According to the gas cooling device for the vacuum drying box, high-temperature and high-humidity gas can be prevented from directly acting on the vacuum pump, and the service life of the vacuum pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of vacuum drying, in particular to a gas cooling device and a vacuum drying box for a vacuum drying box. Background technique [0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. When working, it can maintain a certain degree of vacuum in the working room and can fill the interior with inert gas, especially for some items with complex components. Fast drying, using intelligent digital temperature regulator for temperature setting, display and control. [0003] The existing patent name is "A New Type of Vacuum Drying" and the Chinese utility model patent with the publication number CN210638392U. This patent sets control switches, placement racks, heating wires, valves, vacuum pumps, etc. in the box to dry items. The vacuum pump is started by controlling the switch, so that the box is in a negative pressure state, and the heating wi...
