Embodiment Construction

[0028] The content of the present invention will be further described in detail below in conjunction with specific embodiments. The screen cooling device is composed of a screen placement plate 1, an insulation base plate 2, an insulation cover plate 3, and a Stirling refrigerator 4. Wherein, the cold end of the Stirling refrigerator 4 is used to supply and cool the screen placement plate 1 . A groove for inlaying the above-mentioned screen placement board 1 is provided on the heat preservation bottom plate 2, and the depth of the groove is not less than the sum of the thicknesses of the screen placement board 1 and the screen. Both the heat-insulation base plate 2 and the heat-insulation cover plate 3 are made of heat-insulating materials. After the screen is put in place, the heat-insulating cover plate 3 is attached to the upper surface of the heat-insulating bottom plate 2 immediately. In the actual working process, there is no need to perform positioning and clamping op...

Abstract

The invention relates to a screen cooling device adopting a Stirling refrigerator as a cold source. The screen cooling device comprises a screen storage plate, a heat preservation bottom plate, a heatpreservation cover plate and the Stirling refrigerator, wherein cold is supplied to the screen storage plate for cooling by the cold end of the Stirling refrigerator. The heat preservation bottom plate is provided with a groove for inlaying the screen storage plate, and the depth of the groove is not smaller than the sum of the thickness of the screen storage plate and the thickness of a screen.The heat preservation bottom plate and the heat preservation cover plate are each made of a heat insulating material. When the screen is put in place, the heat preservation cover plate is attached tothe upper surface of the heat preservation bottom plate immediately so that the cold can be prevented from leaking out. In the actual working process, only the operation of putting the screen on the screen storage plate is needed without positioning and clamping, and the design structure is quite simple. In addition, the Stirling refrigerator is adopted by the screen cooling device as the cold source, ultralow temperature of minus 130 DEG C can be conveniently achieved, and the time of manual maintenance is shortened due to high running reliability of the Stirling refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerator manufacturing, in particular to a screen cooling device using a Stirling refrigerator as a cold source. Background technique [0002] As mobile phones enter the era of smart touch screens, it is particularly important to repair the touch screen easily when it is damaged. The existing solution is to use a low-temperature cold plate to cool the screen. As the temperature decreases, the bonding force between the screen and the mobile phone decreases, so that the broken screen can be easily removed for replacement. Most of the existing screen coolers use cascade or mixed working medium vapor compression cycle refrigeration, which consumes a lot of energy and is difficult to reach a lower temperature. It is necessary to develop a screen cooler that can reach the liquid nitrogen temperature zone. Contents of the invention [0003] In order to solve the problems existing in the above-mentioned t...
