[0002] Freezers are often used in scientific research, industrial manufacturing, medicine, aerospace and other fields to maintain extremely low temperatures, usually below liquid nitrogen (-196°C) or liquid argon (-196°C), or even lower. In order to maintain extremely low temperatures, ultra-low temperature freezers usually adopt efficient insulation design to reduce heat conduction and radiation. This includes the use of multiple layers of insulation materials and effective seals to prevent external heat from entering the system. Ultra-low temperature freezers are usually equipped with efficient refrigeration systems, including compressors, condensers and evaporators.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

A heat dissipation fan is connected to one end of the rotating rod. The above design is conducive to preventing motor process from causing malfunctions.

[0010] Furthermore, an eccentric shaft is connected to the front of the cooling fan, a sliding plate is slidably installed on the top of the fixed plate, a sliding groove is provided on the back of the sliding plate, and a scraper is connected to the front of the sliding plate. The above design is conducive to heat dissipation inside the body.

[0015] 1. The utility model cooperates with the components such as the motor, the transmission gear, the rack, the pressing block, the telescopic rod, etc. When the device is used, the stabilizing plate contacts the ground, increasing the overall contact area with the ground, thereby increasing the friction of the machine body to make it more stable when placed, avoiding collision and friction caused by external forces that cause the machine to deviate, thereby causing secondary damage to the machine body and affecting the normal operation of the machine.

[0016] 2. The utility model cooperates with components such as heat dissipation ports, heat dissipation fans, eccentric shafts, and scrapers. Ultra-low temperature freezers usually need to maintain very low temperatures, but sometimes temperature fluctuations need to be controlled to ensure stable working conditions. The heat dissipation device can help evenly distribute the temperature and reduce the temperature gradient, thereby improving temperature stability. Under extremely low temperature conditions, the humidity in the air may cause frost or condensation on the inner wall of the freezer. The heat dissipation device can help reduce humidity and reduce the occurrence of frost and condensation, thereby reducing the maintenance requirements of the equipment. The scraper scrapes away dust attached to the heat dissipation port to better achieve the heat dissipation effect.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
