DETAILED DESCRIPTION

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] A portable electrical equipment heat dissipation device for electrical engineering, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it includes a shell 1, a movable plate 2, a quick buckle 8, a fan 14, a heat sink 15, a partition 19 and a limit plate 81. A groove 3 is opened on the top of the front side of the shell 1, and the movable plate 2 is slidably arranged on the front side of the shell 1 through the groove 3, and a groove is opened on the lower front side of the movable plate 2, and the movable plate 2 can be moved out of the groove 3 on the shell 1 through the groove. Two partitions 19 are provided on the inner side of the shell 1, and exhaust ports 20 are opened inside the two partitions 19. The bottom of the upper partition 19 and the top of the lower partition 19 are both provided with connecting grooves 18. The heat sink 15 is slidably arranged between the two partitions 19 through the connecting grooves 18. Fans are provided on the inner side of the bottom of the shell and the top of the partition on the upper side. Ventilation ports corresponding to the positions of the fan 14 are respectively opened on the upper front side of the movable plate 2 and the lower rear side of the shell 1. A quick buckle 8 is provided on the rear side of the shell 1, and a limit plate 81 is provided on the outer side of the shell 1.

[0022] like Figure 4 As shown, the quick buckle 8 includes an inclined block 11, a mounting frame 12 and a first spring 13. The mounting frame 12 is arranged on the rear side of the shell 1. There are four mounting frames 12 and they are respectively located at the four corners of the rear side of the shell 1. A rectangular hole is opened on the outward side of the mounting frame 12. The inclined block 11 is slidably arranged in the mounting frame 12 through the rectangular hole. A first spring 13 is connected between the mounting frame 12 and the inclined block 11.

[0023] like Figure 3 As shown, it also includes a joystick 4, a crank 5, a slider 6, a U-shaped rod 7, a fixed block 71 and a connecting rod 9. The fixed block 71 is symmetrically provided on the rear side of the shell 1. A through hole is opened in the fixed block 71. The U-shaped rod 7 is slidably arranged on the rear side of the shell 1 through the through hole. The joystick 4 rotates through the lower part of the shell 1. The rear end of the joystick 4 is connected to the crank 5. The lower part of the U-shaped rod 7 is slidably provided with a slider 6. The slider 6 is movably connected to the crank 5. A slide groove 10 is opened on the inclined block 11. A connecting rod 9 is arranged in each slide groove 10. The connecting rod 9 is connected to the U-shaped rod 7.

[0024] like Figure 6 As shown, it also includes an arc-shaped fixing plate 16, a second spring 17 and a connecting block 22. The connecting blocks 22 are symmetrically provided at the top of the upper partition 19 and the bottom of the lower partition 19. The arc-shaped fixing plate 16 is connected between the left and right connecting blocks 22 through the second spring 17. The arc-shaped fixing plate 16 is slidably connected to the partition 19, and the arc-shaped fixing plates 16 on the upper and lower sides are slidably connected to the partitions 19 on the upper and lower sides respectively.

[0025] like Figure 2 As shown, a rubber block 21 is also included. A rubber block 21 is provided on the rear side of the limiting plate 81. The rubber block 21 can increase the friction between the limiting plate 81 and the outer wall of the electrical equipment to ensure that the heat dissipation device is installed more firmly and prevent loosening.

[0026] A square hole of the same size as the heat sink is opened on the outside of the electrical device, and then the heat sink is inserted into the square hole. The frame on the outside of the electrical device can move the inclined block 11 into the installation frame 12 by squeezing the inclined surface on the inclined block 11. When the installation frame 12 moves to the inside of the electrical device, the inclined block 11 is moved out of the installation frame 12 under the action of the first spring 13, and cooperates with the limit plate 81 to achieve rapid installation and fixation. After installation, the two fans 14 are started. The fan 14 located at the bottom sucks the hot air in the electrical device into the heat sink. The hot air flows on the surface of the heat sink 15. The heat sink 15 absorbs the heat in the hot air. The fan 14 located at the top discharges the air cooled by the heat sink 15 to the outside of the electrical device. When the heat dissipation device fails, it is too inconvenient to manually move the inclined block 11 into the installation frame 12 from the inside of the electrical device. By turning the joystick 4, the crank 5 on the joystick 4 rotates, thereby driving the U-shaped rod 7 on the rear side of the housing 1 to move downward through the slider 6. The connecting rod 9 on the U-shaped rod 7 squeezes the slide groove 10 to move the inclined block 11 into the installation frame 12, and then the heat dissipation device is directly pulled out from the outside of the electrical device, thereby achieving quick and convenient disassembly. In traditional heat dissipation devices, the fan 14 and the heat sink 15 are usually fixed by screws. Although this fixing method is reliable, the replacement speed is slow. When replacing the fan 14 of the heat dissipation device, the movable plate 2 can be pulled upward out of the groove 3 to open the heat dissipation device, and then the arc-shaped fixing plate 16 is pulled open and the old fan 14 is taken out from the two arc-shaped fixing plates 16, and then the new fan 14 is squeezed between the two arc-shaped fixing plates 16. The two arc-shaped fixing plates 16 fix the fan 14 under the action of the second spring 17; when replacing the heat sink 15, the movable plate 2 is pulled upward out of the groove 3 to open the heat dissipation device, and the old heat sink 15 is taken out from the partition 19 and replaced with a new heat sink 15.

[0027] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
