Description

Technical Field

[0001] This utility model relates to the field of automotive central control box heat dissipation technology, and in particular to an automotive central control box heat dissipation device. Background Technology

[0002] The car's central control box is usually installed in an open mounting box behind the front wall of the center console. Its main function is to control the car's air conditioning, audio, and other comfort and entertainment devices. It also controls the door lock system, allowing the driver to control the opening and closing of all the car's doors and the window lifting system through the central control box, ensuring that the driver can easily manage various vehicle devices. The central control box integrates fuses and relays, which can effectively control and protect the vehicle's circuitry. The circuit board is usually called the central circuit board, and it plays an important role in the vehicle's electrical system.

[0003] However, circuit boards generate a lot of heat when working for a long time, and the heat needs to be dissipated in time. Currently, the common method for heat dissipation in automotive central control boxes is to add a cooling fan inside the central control box. This method may cause the heat dissipation performance of the central control box to be unable to keep up with the actual needs when the car is working for a long time. Based on this, a heat dissipation device for automotive central control boxes is proposed. Utility Model Content

[0004] To solve the technical problem of heat dissipation in automotive central control boxes, this utility model provides a heat dissipation device for automotive central control boxes.

[0005] This utility model is achieved using the following technical solution: a heat dissipation device for a car central control box, including a central control box, with multiple connecting rods inserted into the upper side of the central control box, and a cooling box fixedly connected to the upper ends of the multiple connecting rods. Multiple slots are opened on the upper side of the central control box, and a protrusion communicating with the lower side of the cooling box is provided inside each slot. A wind-cooling heat dissipation mechanism is provided inside the cooling box, and a central control screen is fixedly connected to one side of the central control box.

[0006] As a further improvement to the above solution, the air-cooled heat dissipation mechanism includes a vortex heat dissipation pipe installed inside the cooling box. A sealing groove is provided on the lower side of the cooling box, and an air inlet pipe is fixedly connected to the inner side of the sealing groove. The upper end of the air inlet pipe is connected to one end of the vortex heat dissipation pipe, and the lower end of the air inlet pipe extends downward into the interior of the central control box. A fan is installed inside the central control box, and the lower end of the air inlet pipe is connected to the fan.

[0007] As a further improvement to the above solution, the other end of the vortex heat dissipation pipe is connected to an air outlet pipe, which extends outward from the cooling box.

[0008] As a further improvement to the above solution, ventilation slots are provided on both sides of the central control box.

[0009] As a further improvement to the above solution, docking plates are fixedly connected to both sides of the central control box.

[0010] As a further improvement to the above solution, a circuit board is fixedly connected inside the central control box, and multiple wiring terminals are provided on the side of the central control box away from the central control screen. The wiring terminals, the central control screen and the circuit board are all electrically connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model has a fan installed inside the central control box. On the one hand, the fan rotates and drives air from the ventilation slot into the central control box. The heat generated by the circuit board enters through the air inlet pipe and is then discharged through the vortex heat dissipation pipe and the air outlet pipe. At the same time, the protrusion connected to the lower side of the cooling box penetrates into the central control box through the slot and absorbs the heat inside the central control box through heat transfer. The heat is directly transferred to the coolant in the cooling box. The heat is then absorbed by the air through the vortex heat dissipation pipe in the cooling box and discharged, thus achieving the effect of heat dissipation.

[0013] 2. This utility model enables the rapid assembly of the central control box and the cooling box through a connecting rod, facilitating the smooth insertion of multiple protrusions into the central control box through slots, thus giving the central control box heat dissipation device of this utility model the advantages of easy installation and disassembly.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figures 1-6 This embodiment of a car central control box heat dissipation device includes a central control box 1. In this utility model, four connecting rods 6 are inserted into the upper side of the central control box 1. The lower end of the connecting rods 6 is fixed to the central control box 1 by threaded connection. The upper ends of the four connecting rods 6 are fixedly connected to a cooling box 5. Eight slots 7 are opened on the upper side of the central control box 1. Each slot 7 has a protrusion 11 that communicates with the lower side of the cooling box 5. The surface of the protrusion 11 is provided with pleats to increase the contact area and accelerate the heat dissipation effect. The cooling box 5 is provided with an air-cooled heat dissipation mechanism. A central control screen 2 is fixedly connected to one side of the central control box 1.

[0025] Please combine Figure 5 As shown, the air-cooled heat dissipation mechanism includes a vortex heat dissipation pipe 13 installed inside the cooling box 5. A sealing groove 14 is provided on the lower side of the cooling box 5. A sealing ring is installed inside the sealing groove 14 to prevent the coolant in the cooling box 5 from leaking. An air inlet pipe 15 is fixedly connected to the inner side of the sealing groove 14. The upper end of the air inlet pipe 15 is connected to one end of the vortex heat dissipation pipe 13. The lower end of the air inlet pipe 15 extends downward into the interior of the central control box 1. A fan 10 is installed inside the central control box 1. The lower end of the air inlet pipe 15 is connected to the fan 10.

[0026] Please combine Figure 4 As shown, the other end of the vortex heat dissipation pipe 13 is connected to the air outlet pipe 9, which extends outward from the cooling box 5. The air outlet pipe 9 can be connected to the exhaust channel to dissipate heat to the outside of the vehicle.

[0027] Please combine Figure 2 As shown, ventilation slots 3 are provided on both sides of the central control box 1, and the ventilation slots 3 are composed of multiple ventilation openings.

[0028] Please combine Figure 1 As shown, docking plates 14 are fixedly connected to both sides of the central control box 1, and the central control box 1 is fixedly connected to the interior of the vehicle through the docking plates 14.

[0029] Please combine Figure 3 As shown, a circuit board 12 is fixedly connected inside the central control box 1. Two wiring terminals 8 are provided on the side of the central control box 1 away from the central control screen 2. The wiring terminals 8 and the central control screen 2 are electrically connected to the circuit board 12.

[0030] The implementation principle of the heat dissipation device for a car central control box in this embodiment is as follows: The operator can install the central control box 1 inside the center console in the driver's cabin through the docking plate 14, and connect the central control box 1 to the vehicle's electrical system through the wiring terminals 8. When the fan 10 is started, the fan 10 can drive the air outside the central control box 1 into the interior of the central control box 1 through the ventilation slot 3. After the external air mixes with the heat generated by the circuit board 12, it enters the vortex heat dissipation pipe 13 in the cooling box 5 through the air inlet pipe 15 on the upper side of the fan 10, and then is discharged from the air outlet pipe 9 connected to the other end of the vortex heat dissipation pipe 13. At the same time, the protrusion 11 on the lower side of the cooling box 5 extends into the interior of the central control box 1 through the slot 7, and absorbs the high temperature heat inside the central control box 1 through heat transfer. The heat is directly transferred to the coolant in the cooling box 5. When the air circulates in the vortex heat dissipation pipe 13 in the coolant, the coolant can transfer the heat it absorbs to the air in the vortex heat dissipation pipe 13, and finally be discharged from the air outlet pipe 9, thus achieving the heat dissipation effect.
