[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: LCD display cooling device, please see Figures 1 to 3 , including a frame 1, a fan 2, a dust plate 3, a sliding block 4, a reset spring 5, a rotating rod 6, a fixed rod 61, a torsion spring 62, a sponge ring 7, a condenser 8 and a refrigerator 9. The fan 2 is symmetrically installed in the frame 1. The dust plate 3 is connected to the air outlet positions corresponding to the two fans 2 on the rear side of the frame 1. The sliding blocks 4 are connected to both sides of the frame 1. The sliding blocks 4 are connected to the frame 1 with reset springs 5, and the reset springs 5 ​​are placed inside the sliding blocks 4. The middle top surface and the bottom surface of the frame 1 are connected. A rotating rod 6 is rotatably connected therebetween, and two rotating rods 6 are provided and symmetrically arranged. A fixed rod 61 is connected in the middle of the ends close to each other of the two rotating rods 6. Torsion springs 62 are connected between the fixed rods 61 and the frame 1, and the torsion springs 62 are both sleeved on the adjacent fixed rods 61. Sponge rings 7 are sleeved on the ends away from each other of the two rotating rods 6. Condensation tubes 8 are connected to the front sides of the dustproof plates 3. A refrigerator 9 is installed at the center position of the rear side of the frame 1, and the ends where the two condensation tubes 8 converge are communicated with the refrigeration port of the refrigerator 9.

[0019] When the heat sink is needed to dissipate heat from the LCD screen, the heat sink is first installed on the back of the LCD screen, and a mounting groove that matches the heat sink is provided on the back of the LCD screen. In the specific operation, the heat sink is then buckled into the mounting groove of the LCD screen. Initially, the torsion spring 62 is in a non-deformed state, the two rotating rods 6 are in an inwardly close state, the two rotating rods 6 and the sponge ring 7 are pushed open by the components on the back of the LCD radiator, the torsion spring 62 is deformed, and the sponge ring 7 rotates when in contact with the components. Since the sponge ring 7 is made of a soft material, it can wipe the dust on the surface of the component to play a cleaning role without causing damage to the component. After the heat sink is placed on the back of the LCD screen, the front side of the sliding block 4 is designed as a bevel, so when the sliding block 4 contacts the back of the LCD screen, the sliding block 4 will be squeezed and slide inward, and the reset spring 5 will shrink inward. When the sliding block 4 is in place, the sliding block 4 will slide outward and be stuck on the LCD screen under the action of the reset spring 5. In this way, the installation of the heat sink can be completed. When the LCD screen is in use, the fan 2 and the refrigerator 9 can be started. The wind generated by the fan 2 can blow away the heat generated by the LCD screen. At the same time, the refrigerator 9 cools the condenser 8, turning the hot wind into cold wind and then discharging it, which is beneficial to the heat dissipation of the entire LCD screen.

[0020] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
