DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is based on the ideal embodiments of the present utility model as inspiration. Through the following description, relevant staff can make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and must be determined according to the scope of the claims.

[0021] With reference to the following drawings, the present utility model will be further described:

[0022] As Figures 1 to 6As shown in the figure, an energy-efficient thermal freeze dryer has a housing 100. A vacuum chamber 200, a vacuum pump 300, and a compressor 400 are provided in the housing 100. A freeze-drying chamber 210 and a coil chamber 220 are provided in the vacuum chamber 200. A heat-conducting coil 500 is provided in the coil chamber 220. A freeze-drying rack 600 is provided in the freeze-drying chamber 210. Multiple layers of plates 610 are provided on the freeze-drying rack 600. A heat-conducting channel is provided in the plate body 611 of the plate 610. The heat-conducting channel communicates with the heat-conducting coil 500 in the coil chamber 220. The heat-conducting coil 500 is connected to the compressor 400.

[0023] A vacuum pump 300 and its control box 310 are provided at the upper part of the vacuum chamber 200. The vacuum pump 300 is connected to the vacuum chamber 200.

[0024] A diversion groove is formed in the plate body 611. The heat-conducting coil 500 is connected to the notch of the diversion groove. Of course, it is also possible that a diversion coil is provided in the plate body 611, and the heat-conducting coil 500 is connected to the diversion coil. Both the diversion groove and the diversion coil are a type of heat-conducting channel, which is used for guiding when the heat-conducting medium flows in the plate body 611. In actual application, the heat-conducting channel is arranged in an S-shaped bend in the plate body 611.

[0025] The compressor 400 is a heat pump compressor. In the prior art, heat pump compressors are commonly used in heat pump air conditioners. While having a refrigeration function, they can also absorb low-grade heat energy in the surrounding environment, and then do work through electricity, so as to convert it into high-grade heat energy that can be utilized, which is more convenient and has better effects when used.

[0026] A panel 612 is provided above the plate 610. The panel 612 is made of a heat-conducting material.

[0027] A partition 230 is provided between the freeze-drying chamber 210 and the coil chamber 220. A fan 231 and an air inlet 232 are installed on the partition 230. In this way, the heat energy from the coil chamber 220 is directed towards the plate 610 through the air inlet 232, which can also effectively save energy.

[0028] As Figure 5 As shown in the figure, a coil support 510 is provided between adjacent heat-conducting coils 500.

[0029] When the present utility model is in use, first, the compressor 400 starts the refrigeration mode. The heat-conducting medium flows along the heat-conducting coil 500 into the heat-conducting channel in the plate body 611 of the plate 610 to cool the material and freeze the material into ice crystals. Then, the vacuum pump 300 evacuates the air. Finally, the compressor 400 switches to the heating mode. The heated heat-conducting medium also flows along the heat-conducting coil 500 into the heat-conducting channel in the plate body 611 of the plate 610 to heat the material and sublimate the moisture in the material to achieve freeze-drying.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
