Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted integrated central control machines, and in particular to a heat dissipation structure for improving the heat tolerance performance of a vehicle-mounted integrated central control machine. Background Art

[0002] The vehicle-mounted integrated computer is a comprehensive vehicle-mounted electronic device that integrates multiple functions and devices. Its original design intention is to integrate multiple functions such as computing, display, control and communication into one device for easy installation inside the vehicle. Affected by high temperatures, the temperature inside the car increases significantly, and high temperatures will affect the operating performance of the vehicle-mounted central control integrated computer. This requires a heat dissipation structure with heat resistance to ensure the normal operation of the vehicle-mounted integrated computer.

[0003] Currently, the heat dissipation structure of the vehicle-mounted central control all-in-one machine is simple, and heat is dissipated by installing heat dissipation fins. Since the central control all-in-one machine is installed in the car, the ventilation effect is poor, and the heat dissipation efficiency of the heat dissipation fins is poor in a high temperature environment, resulting in the internal temperature of the vehicle-mounted central control all-in-one machine being too high. Under high temperature conditions, the vehicle-mounted central control may become stuck at the least, and the internal chip of the vehicle-mounted all-in-one machine may be damaged at the worst. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcoming of poor efficiency of the heat dissipation structure of the vehicle-mounted central control all-in-one machine in the prior art, and to propose a heat dissipation structure for improving the heat tolerance performance of the vehicle-mounted central control all-in-one machine.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Embodiment: This embodiment provides a heat dissipation structure for improving the heat tolerance performance of the vehicle-mounted central control integrated machine, see Figure 1-6 Specifically, it includes a metal plate 1, a sealing frame 11 installed on the inner side of the metal plate 1, an outer plate 12 and a screen installation frame 13 installed on the outer side of the outer plate 12, a honeycomb heat dissipation plate 14 is fixedly provided on the outer side of the metal plate 1, and the ventilation slots on the honeycomb heat dissipation plate 14 are connected with the metal plate 1, and the outer side of the honeycomb heat dissipation plate 14 is surrounded by a trapezoidal protective cover 15, and a heat dissipation fan 16 is fixedly provided at the end of the protective cover 15, and an upper heat dissipation slot 17 and a side heat dissipation slot 18 are opened on the top and side of the sealing frame 11, and dustproof nets are fixedly provided on the inner walls of the upper heat dissipation slot 17 and the side heat dissipation slot 18, and two baffles 7 are symmetrically provided on the upper surface of the sealing frame 11, and the two sides of the baffle 7 are in contact with the metal plate 1 and the outer plate 12, and a sealing gasket 6 is fixedly provided on the inner side of the outer plate 12, and the sealing gasket 6 is in contact with the inner wall of the sealing frame 11;

[0028] The metal plate 1, the sealing frame 11 and the outer plate 12 keep the inside of the sealing frame 11 sealed, and the two baffles 7 block the top of the sealing frame 11, and the circuit board used by the vehicle-mounted central control integrated machine is installed in the sealing frame 11, with one side of the circuit board facing the metal plate 1 to prevent water vapor from entering and causing damage to the circuit board, and then the screen is installed in the screen installation frame 13, and a honeycomb heat sink 14 is installed on the outside of the metal plate 1, and the wind is sent from the protective cover 15 to the sealing frame 11 from the honeycomb heat sink 14 through the heat dissipation fan 16. The honeycomb heat sink 14 guides the wind to various positions of the circuit board to increase the heat dissipation area, and the protective cover 15 sends the gathered wind to the honeycomb heat sink 14, and the wind entering the sealing frame 11 is discharged from the upper heat dissipation groove 17 to achieve ventilation, and a dustproof net is provided on the upper heat dissipation groove 17 to block dust, and a sealing gasket 6 is provided on one side of the outer plate 12, and the sealing gasket 6 is in contact with the inner side of the sealing frame 11 to increase the sealing performance of the sealing frame 11.

[0029] In the specific implementation process, Figure 4 and Figure 5 As shown, ventilation and heat dissipation components and cold air heat dissipation components are provided on both sides of the sealing frame 11 between the metal plate 1 and the outer plate 12. The ventilation and heat dissipation components include two limit rods 2 fixed on the inner side of the metal plate 1, and connecting blocks 21 are slidably provided on the limit rods 2. A sealing plate 23 is fixed at the end of the connecting block 21. A spring 22 is sleeved on the limit rod 2. The sealing plate 23 is located on one side of the side heat dissipation groove 18. A button 24 is fixedly provided in the middle of the sealing plate 23. One end of the button 24 passes through the outer plate 12. A guide rod 3 and an elastic shift block 31 are fixed in the groove of the outer wall of one side of the sealing frame 11. A clamping block 32 is fixedly provided on one side of the sealing plate 23. The clamping block 32 is fitted with the upper surface of the guide rod 3. The part of the button 24 located on the outer side of the outer plate 12 is fixedly provided with an anti-sliding block 5, and the anti-sliding block 5 is made of rubber.

[0030] When the temperature inside the vehicle is too high, by pressing the button 24, the button 24 drives the sealing plate 23 to move, and the sealing plate 23 moves along the limit rod 2 through the connecting block 21, and squeezes the spring 22, so that the sealing plate 23 moves away from the side heat dissipation groove 18, thereby increasing the ventilation volume in the sealing frame 11, allowing the air in the sealing frame 11 to circulate, reducing the temperature in the sealing frame 11, and ensuring the stability of the vehicle-mounted central control integrated machine. When the sealing plate 23 moves, it drives the clamping block 32 to move along the guide rod 3, and finally clamps at the end position of the guide rod 3, so that the sealing plate 23 The position is fixed, which is convenient for ventilation of the side heat dissipation groove 18. When the sealing frame 11 needs to be closed, the button 24 is pressed again, and the sealing plate 23 drives the block 32 to continue to move. The inclined surface at the end of the block 32 contacts the elastic block 31, and the block 32 moves to the top of the elastic block 31. Finally, the button 24 is released, and the sealing plate 23 is pushed by the spring 22. Since the height of the elastic block 31 is greater than the guide rod 3, the block 32 falls directly from the elastic block 31 to the guide rod 3. Finally, the sealing plate 23 is reset to block the side heat dissipation groove 18, which is convenient for ventilation and heat dissipation of the side heat dissipation groove 18.

[0031] In the specific implementation process, Figure 1 and Figure 6 As shown, the cold air heat dissipation assembly includes a heat dissipation copper tube 4 fixedly mounted on one side of the sealing frame 11, both ends of the heat dissipation copper tube 4 pass through the outer plate 12, and both ends of the heat dissipation copper tube 4 are fixedly provided with a dust cover 41, and the openings of the dust cover 41 are downward;

[0032] The end of the heat dissipation copper tube 4 is located on the outside of the outer panel 12, and the outside of the outer panel 12 is inside the vehicle. When the air conditioner is turned on in the vehicle, cold air will enter the heat dissipation copper tube 4 from under the dust cover 41. The heat dissipation copper tube 4 is in contact with the outer wall of the sealing frame 11, and the heat in the sealing frame 11 will be directed to the heat dissipation copper tube 4. The cold air entering the heat dissipation copper tube 4 will take away the heat, thereby achieving effective cooling of the vehicle-mounted central control integrated machine.

[0033] Specifically, the working principle and operation method of the present invention are as follows:

[0034] The cooling fan 16 sends the wind from the protective cover 15 through the honeycomb cooling plate 14 into the sealing frame 11. The honeycomb cooling plate 14 guides the wind to various positions of the circuit board to increase the cooling area, and the protective cover 15 sends the concentrated wind to the honeycomb cooling plate 14. The wind entering the sealing frame 11 is discharged from the upper cooling slot 17 to achieve ventilation. When the temperature in the car is too high, by pressing the button 24, the button 24 drives the sealing plate 23 to move, and the sealing plate 23 moves along the limit rod 2 through the connecting block 21 and squeezes the spring 2 2. The sealing plate 23 moves away from the side heat dissipation groove 18, increasing the ventilation volume in the sealing frame 11, allowing the air in the sealing frame 11 to circulate, reducing the temperature in the sealing frame 11, and ensuring the stability of the vehicle-mounted central control integrated machine; and the heat dissipation copper tube 4 installed on one side of the sealing frame 11, when the air conditioner is turned on in the car, the cold air will enter the heat dissipation copper tube 4 from the bottom of the dust cover 41, and the heat dissipation copper tube 4 will fit the outer wall of the sealing frame 11, which will guide the heat in the sealing frame 11 to the heat dissipation copper tube 4, and the heat will be taken away by the cold air entering the heat dissipation copper tube 4.
