Description

Technical Field

[0001] The utility model relates to the field of dustproof heat dissipation structures, in particular to an electronic equipment heat dissipation structure with dustproof effect. Background Art

[0002] During normal driving, the internal electronic equipment of electric vehicles will inevitably generate high heat. Due to its closed environment, poor heat dissipation will directly affect the service life of the electronic equipment. If it is in a semi-closed state for a long time, it will face the threat of dust. Many electronic devices such as electric vehicle controller boards in electric vehicles not only have to deal with heat dissipation issues, but also have to prevent the dust brought in by the electric vehicle during driving from posing a threat to the use of electronic equipment.

[0003] Many existing electric vehicle heat dissipation designs often directly expose electronic equipment, such as controllers, inside the vehicle. Fan-based heat dissipation is generally ineffective, while some water-cooled structures are more complex. Furthermore, many heat dissipation structures lack dust-proofing capabilities. For structures with dust-proofing capabilities, their openings cannot be closed when not in use, leaving the interior space open to the outside environment and prone to dust accumulation. Once the electric vehicle is started, if a closed space is still used to prevent dust, the heat generated by the electronic equipment will increase, further increasing the burden on heat dissipation. During use, dust ingress is inevitable, and long-term accumulation will affect the service life of the electronic equipment, leading to equipment wear and tear.

[0004] Therefore, those skilled in the art provide an electronic device heat dissipation structure with dustproof effect to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a heat dissipation structure for electronic equipment with a dust-proof effect. The device can combine the heat dissipation structure and the dust-proof structure. The heat dissipation structure can drive the opening and closing of the dust-proof structure, so that the whole structure remains closed to prevent dust accumulation when the electric vehicle is not started. The relevant equipment is concentrated in one box, the layout saves space, and increases the service life of the electronic equipment in the electric vehicle.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation structure for electronic equipment with dustproof effect, comprising a shutter rotatably provided on the front side of the upper end of the bottom plate of the box body, a No. 1 rod rotatably provided on the rear side of the shutter, a No. 2 rod slidably provided on the front and rear sides of a protrusion on one side of the No. 1 rod, a No. 1 spring is provided at the front and rear sides of one side of the No. 2 rod, an electronic equipment cooling box is fixedly provided at the rear side of the upper end of the bottom plate of the box body, a water pump is fixedly provided at the rear side of the electronic equipment cooling box, and a water pump is fixedly provided on the bottom plate of the electronic equipment cooling box A cooling groove is provided at the end, a coolant tank is fixedly provided on the front side of the water pump, a No. 2 pipe is provided through the front side of the coolant tank, a cooling device is fixedly provided at the front side of one side of the electronic equipment cooling box, a No. 1 pipe is provided through the front side of the one side of the electronic equipment cooling box, a harness groove is provided at the upper part of the rear side of the electronic equipment cooling box, a transfer block is fixedly provided at the rear outlet of the No. 1 pipe, a movable rod is provided through one side of the transfer block, a No. 2 spring is provided on the other side of the movable rod, and the other side of the No. 2 spring is provided on the inner wall on the other side of the transfer block;

[0007] A small motor is fixedly provided on the front side of the upper end of the bottom plate of the box body, dust filter plates are clamped on the upper end and both sides of the small motor, and a suction fan is fixedly provided on the output end of the small motor;

[0008] Through the above technical solution, the water pump will input the coolant into the cooling tank. When the coolant flows through the cooling tank, it will take away the heat from the lower surface of the controller placed above for water cooling and heat dissipation, and the coolant will not leak. After the coolant flows into the transfer block, it will drive the movable rod to move to one side, so that the No. 1 rod and the No. 2 rod move so that the shutter remains open. After the water pump is turned off, the No. 2 spring rebounds to return the movable rod to its original position, so that the shutter is closed. When the movable rod moves to the inner wall of one side of the transfer block, the coolant will flow into the No. 2 pipe. When flowing through the cooling equipment, the coolant that takes away the heat from the controller is cooled, and then flows back to the coolant tank for recycling. The shutters and dust filter plates face the direction of the electric vehicle's movement, effectively absorbing dust caused by the electric vehicle's movement, and preventing dust from contacting electronic equipment such as the controller, which may reduce the life of the electronic equipment. When the electric vehicle is not started, the shutters can be kept closed to prevent external dust from entering.

[0009] Furthermore, the lower end of the shutter is rotatably arranged at the front of the upper end of the bottom plate of the box body, and the upper end of the shutter is rotatably arranged at the front of the lower end of the top cover of the box body;

[0010] Through the above technical solution, the shutters will open or close as the No. 1 rod moves.

[0011] Furthermore, one side of the two No. 1 springs is arranged on the inner wall of one side of the box body, and the front spring of the two No. 1 springs is arranged near the rear side of the No. 1 rod;

[0012] With the above technical solution, after the second rod loses the thrust given by the movable rod, the first spring rebounds the first and second rods to return to their original positions, so that the shutter is closed.

[0013] Furthermore, the water pump output end is connected to the cooling tank inlet, and the coolant flows out of the water pump without leakage;

[0014] With the above technical solution, when the electronic device is fixed on the cooling tank by gluing, the coolant can better take away the heat generated by the electronic device without leaking.

[0015] Furthermore, the second pipe is provided through the cooling device and is cooled by a cooling fan in the cooling device. The front end of the second pipe is provided through the rear side of the transfer block.

[0016] Through the above technical solution, the coolant that takes away the heat from the electronic equipment can be cooled down better and flow back to the coolant tank to better perform the next heat dissipation work.

[0017] Furthermore, the dimensions of the movable rod penetrating the center of one side of the transfer block and the transfer block can better move to one side until reaching the inner wall of one side of the transfer block when pushed by the coolant, and the coolant will not leak.

[0018] Furthermore, one side of the movable rod is fixedly connected to the second rod;

[0019] Through the above technical solution, after the movable rod is pushed by the coolant, the movable rod can drive the second rod to move in the same direction.

[0020] Furthermore, when the interior of the transfer block is filled with coolant, the second spring will remain in a state of reaching the inner wall of one side of the transfer block;

[0021] Through the above technical solution, when the interior of the transfer block is filled with coolant, the coolant can further flow into the No. 2 pipe, thereby better performing the circulation work.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a heat dissipation structure for electronic equipment with dust-proof effect. The device combines water cooling and dust-proofing into one, so that heat dissipation and dust-proofing work together. When the electric vehicle starts, the water pump outputs water-cooling liquid to dissipate heat for the electronic equipment, and at the same time drives the shutters to open, so that the suction fan actively absorbs the surrounding dust and controls the dust to the filter plate. When the electric vehicle stops using, the shutters are closed to prevent the internal environment from communicating with the outside world, avoid dust accumulation, and provide good environmental support for the long-term use of the controller.

[0024] 2. The utility model proposes a heat dissipation structure for electronic equipment with a dust-proof effect. The device is arranged compactly and orderly. While reducing the length of the coolant circulation pipeline, it ensures the heat dissipation effect, improves the smoothness of the coolant circulation, reduces the space occupied by the water cooling pipeline, and is convenient for its overall arrangement in the electric vehicle structure.

A cooling groove 13 is provided at the upper end of the bottom plate. When the water pump 12 is turned on, the coolant is input into the cooling groove 13. A coolant tank 11 is fixedly provided in front of the water pump 12. A No. 2 pipe 10 is provided through the front of the coolant tank 11. A cooling device 9 is fixedly provided at the front of one side of the electronic equipment cooling box 15. The cooling device 9 mainly cools the coolant carrying heat. A No. 1 pipe 6 is provided through the front of one side of the electronic equipment cooling box 15. A wire harness trough 14 is provided at the upper rear side of the electronic equipment cooling box 15 for centrally placing the lines of the electronic equipment. A transfer block 8 is fixed at the rear outlet of the No. 1 pipe 6. A movable rod 7 is provided through one side of the transfer block 8. A No. 2 spring 19 is provided on the other side of the movable rod 7. The other side of the No. 2 spring 19 is provided on the inner wall of the other side of the transfer block 8.

[0033] A small motor 16 is fixedly provided at the front side of the upper end of the bottom plate of the box body 1, and an ash filter plate 17 is clamped on the upper end and both sides of the small motor 16. The ash filter plate 17 faces the forward direction of the electric vehicle. A suction fan 18 is fixedly provided at the output end of the small motor 16. The suction fan 18 actively controls and absorbs dust onto the ash filter plate 17. The water pump 12 inputs the coolant into the cooling tank 13. When the coolant flows through the cooling tank 13, it will take away the heat from the lower surface of the controller placed above for water cooling and heat dissipation, and the coolant will not leak. After the coolant flows into the transfer block 8, it will drive the movable rod 7 to move to one side, so that the No. 1 rod 3 and the No. 2 rod 5 move so that the shutters 2 remains in the open state. After the water pump 12 is turned off, the No. 2 spring 19 rebounds to return the movable rod 7 to its original position, so that the shutter 2 is closed. When the movable rod 7 moves to the inner wall of one side of the transfer block 8, the coolant will flow into the No. 2 pipe 10. When flowing through the cooling device 9, the coolant that takes away the heat of the controller is cooled, and then flows back to the coolant tank 11 for recycling. The shutter 2 and the dust filter plate 17 face the direction of the electric vehicle's movement, effectively absorbing dust caused by the electric vehicle's movement, preventing dust from contacting electronic equipment such as the controller and reducing the life of the electronic equipment. When the electric vehicle is not started, the shutter 2 can be kept closed to prevent external dust from entering.

[0034] The lower end of the shutter 2 is rotatably arranged at the front upper end of the bottom plate of the box body 1, and the upper end of the shutter 2 is rotatably arranged at the front lower end of the top cover of the box body 1. The shutter 2 will open or close with the movement of the No. 1 rod 3. One side of the two No. 1 springs 4 is arranged on the inner wall of one side of the box body 1, and the front spring of the two No. 1 springs 4 is arranged near the back side of the No. 1 rod 3. After the No. 2 rod 5 loses the thrust given by the movable rod 7, the No. 1 spring 4 rebounds the No. 1 rod 3 and the No. 2 rod 5 to return to their original positions, so that the shutter 2 is closed. The output end of the water pump 12 is connected to the inlet of the cooling tank 13, and the coolant flows out of the water pump 12 without leakage. When the electronic equipment is fixed on the cooling tank 13 by gluing, the coolant can better take away the heat generated by the electronic equipment without leaking. The No. 2 pipe 10 is arranged through the cooling device 9 and is cooled by the cooling fan in the cooling device 9. For cooling, the front end of the No. 2 pipe 10 is arranged through the rear side of the transfer block 8, so that the coolant that takes away the heat of the electronic equipment can be cooled down better and flow back to the coolant tank 11 to better perform the next heat dissipation work. The size of the movable rod 7 that is arranged through the center of one side of the transfer block 8 is consistent with the size of the opening on one side of the transfer block 8, so that the movable rod 7 can better move to one side when pushed by the coolant until it reaches the inner wall of one side of the transfer block 8, and the coolant will not leak. One side of the movable rod 7 is fixedly connected to the No. 2 rod 5, so that after the movable rod 7 is pushed by the coolant, the movable rod 7 can drive the No. 2 rod 5 to move in the same direction. When the interior of the transfer block 8 is full of coolant, the No. 2 spring 19 will remain in a state of reaching the inner wall of one side of the transfer block 8, so that when the interior of the transfer block 8 is full of coolant, the coolant can further flow into the No. 2 pipe 10, so as to better perform the circulation work.

[0035] Working principle: First, apply glue to the bottom surface of the electronic device controller that needs to be protected and place it inside the electronic device cooling box 15. The controller line passes through the harness groove 14. After the placement is completed, turn on the water pump 12 to make the coolant flow out of the water pump 12. The coolant flows along the cooling groove 13 and acts on the surface of the controller to achieve cooling and heat dissipation. After the coolant flows out of the cooling groove 13, it flows into the transfer block 8 through the No. 1 pipe 6 and pushes the movable rod 7 to one side, further driving the No. 2 rod 5 and the No. 1 rod 3 to move, so that the shutter 2 remains open. When the electric car is in a stopped state, the water coolant stops entering the No. 2 spring. The spring 19 rebounds, driving the movable rod 7 to move to the other side, thereby driving the No. 2 rod 5 and the No. 1 rod 3 to move, so that the shutter 2 is closed to prevent the shutter 2 from being connected to the external environment when not riding, causing dust to accumulate inside. The coolant flows through the transfer block 8 and then enters the cooling device 9 to cool the coolant that takes away the heat of the controller. After cooling, it flows back to the coolant tank 11 through the No. 2 pipe 10. When you start riding the electric car, turn on the suction fan 18, and the dust filter plate 17 is snap-fitted to the small motor 16, with its opening facing the direction of travel of the electric car, which can collect dust more effectively and is convenient to disassemble for cleaning.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
