[0002] A refrigerator is a machine that transfers heat from a cooled object with a lower temperature to the ambient medium to obtain cooling. The heat transferred from the lower temperature object is usually called cooling. The working fluid participating in the thermodynamic process changes in the refrigerator is called refrigerant. The refrigeration temperature range is usually above 120K, and below 120K belongs to the deep low temperature technology range. Refrigerators are widely used in industrial and agricultural production and daily life. In order to avoid excessive temperature when the refrigerator is working, a heat dissipation device is usually provided for heat dissipation.

[0004] The above scheme effectively improves the heat conduction effect through the copper-aluminum alloy heat sink, so that the temperature of the refrigerator body is quickly conducted. However, the device needs to use additional tools to remove the positioning nuts when inspecting and maintaining the fan, and the disassembly process is relatively troublesome. Similarly, the positioning nuts need to be installed multiple times during installation, which makes the overall disassembly and assembly inconvenient and affects work efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a graphene heat dissipation device for refrigerators that is easy to disassemble and assemble. Utility Model Content

[0016] 1. The utility model provides transmission chambers at the upper and lower ends of the main shell, and the double-threaded transmission rod can be rotated by turning the knob.

[0032] See also Figure 1 , Figure 2 and Figure 3 A plurality of heat-conducting rods 5 distributed in a rectangular array are arranged at the front end of the graphene heat sink 4, and a heat-insulating plate 12 is arranged at the rear side of the heat-dissipating shell 2. A plurality of through holes distributed in a rectangular array are opened inside the heat-insulating plate 12, and the size of the through holes is adapted to the heat-conducting rods 5.

[0035] See also Figure 1 , Figure 2 and Figure 3 The two sides and the upper and lower ends of the main shell 1 are integrally formed with mounting plates 3, and the setting of the mounting plates 3 can be used to install the main shell 1.

[0036] Working principle: when in use, the main shell 1 is installed at the heat dissipation position of the refrigerator through the mounting plate 3, so that the graphene heat sink 4 is fitted with the heat dissipation position, the protective cover 21 is opened and the knob 20 is turned, the knob 20 will drive the damping shaft 19 to rotate, the damping shaft 19 will drive the double-threaded transmission rod 7 to rotate, and the double-threaded transmission rod 7 will drive the two movable plates 9 to rotate synchronously. Since the movable plates 9 are slidably matched with the guide rod 8, the movable plates 9 will be axially limited, and the rotation of the two movable plates 9 will be converted into opposite or opposite horizontal linear movement, so that the movement of the two movable plates 9 towards each other can drive the limit block 10 to move synchronously, and the rear end of the heat dissipation shell 2 is inserted into the main shell 1, and the heat conducting rod 5 will pass through the through hole opened in the heat insulation plate 12, so that the limit block 10 is inserted into the inside of the limit groove 11, so that the heat dissipation shell 2 can be clamped and fixed, and the installation of the heat dissipation shell 2 can be completed. When disassembling, only the knob 20 needs to be rotated in the opposite direction to move the limit block 10 out of the inside of the limit groove 11, releasing the heat dissipation. The shell 2 is clamped and fixed, and there is no need to use multiple screws to fix it throughout the whole process, so that convenient and quick disassembly and assembly can be achieved. The protective cover 21 is closed when the knob 20 is not turned. The protective cover 21 can avoid accidental touching of the knob 20, thereby improving safety. During daily heat dissipation, the graphene heat sink 4 can transfer heat to the heat conducting rod 5, and the heat conducting rod 5 will transfer the heat to one end inside the heat dissipation shell 2. The heat insulation board 12 can prevent heat from contacting the graphene heat sink, thereby preventing heat reflux and improving the heat dissipation effect. The micro motor 17 is started to drive the gear 16 to rotate in the forward and reverse directions. Since the gear 16 is meshed and connected with the rack 14, the movable frame 15 can be moved under the rotation of the gear 16. At this time, the cooling fan 18 is started, so that the cooling fan 18 can move back and forth in the left and right directions under the heat dissipation port 13. The work of the cooling fan 18 itself can accelerate the dissipation of heat, thereby achieving a more efficient heat dissipation effect.
