Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted controllers, in particular to a heat dissipation structure of a vehicle-mounted controller. Background Technique

[0002] In the prior art, a heat dissipation module is generally set for a vehicle-mounted controller to improve the heat dissipation effect of the vehicle-mounted control. Generally, the heat dissipation module is divided into two types. One is an independent radiator. The independent radiator has a small volume and is adapted to various position boards, but the heat dissipation effect is relatively poor. The other is an integrated structure radiator. The integrated structure radiator is a whole heat dissipation block with a large volume and a relatively strong heat dissipation effect. However, the processor board needs to be at the edge of the chassis. The radiator connects the processor chip to be cooled with the chassis shell, and dissipates heat through the shell. At the same time, the corresponding board is not convenient to disassemble. When the processor board to be cooled is in the middle part of the controller chassis, the existing independent radiator has a low heat dissipation effect and is not sufficient to supply the heat dissipation effect, while the integrated structure radiator is not convenient to connect. Therefore, there is a need to solve the above problems and provide a heat dissipation structure that can meet the heat dissipation effect of vehicle-mounted control and is convenient to connect with the processor board set in the middle of the control box. For this reason, the utility model proposes a heat dissipation structure of a vehicle-mounted controller to solve the above problems. Content of the Utility Model

[0018] Embodiment 1

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a heat dissipation structure of a vehicle-mounted controller, including

[0020] a radiator 2, which includes two parts: a heat conduction component and a heat dissipation component. Among them, the heat conduction component part is fixedly connected to the board on the inside of the controller box 1 and is attached to the component, and the heat dissipation component part is fixedly connected to the outer side wall of the controller box 1. The two parts are connected by a heat conduction copper tube 10 for heat conduction. Both ends of the heat conduction copper tube 10 communicate with a coolant tank 3, and the coolant tank 3 is fixed outside the controller box 1;

[0021] There are multiple groups of boards arranged inside the controller box 1, and components are arranged on the boards. One side of the component is attached and connected to the heat conduction component part of the radiator 2;

[0022] The heat conduction component includes a heat conduction plate 5. Four corners on one side of the heat conduction plate 5 protrude with connecting columns, and the connecting columns are fixedly connected to one side of the component by bolts. The other side of the heat conduction plate 5 is fixedly connected to a connecting plate 4 by bolts. The heat conduction copper tube 10 is clamped and positioned inside by combining the heat conduction plate 5 and the connecting plate 4. The structure of the heat conduction component is small, and the requirement for the installation space is low. It can conduct heat in a relatively narrow space. Through the heat conduction component, it can accurately fit the outside of the component that needs heat conduction and heat dissipation, effectively improving the heat conduction and heat dissipation effect, and the installation is also more convenient and fast;

[0023] The heat dissipation component includes a fixed seat 7, which is fixedly connected to the outer wall of the controller box 1 by bolts. The upper end of the fixed seat 7 is fixedly connected to a heat dissipation plate 8 by bolts. The heat conduction copper tube 10 is clamped and fixed between the fixed seat 7 and the heat dissipation plate 8. Through the heat dissipation component, it can cooperate with the heat conduction copper tube 10 to dissipate the heat conducted out by the heat conduction component to the outside. The heat dissipation point is outside the controller case 1, and there is no need for the controller case 1 housing to bear the heat dissipation carrier anymore. The heat dissipation effect is stronger, and it is more convenient to use. It can adapt to different application scenarios and increase the adaptability;

[0024] A number of evenly distributed heat dissipation fins 9 protrude from the outside of the heat dissipation plate 8, and a heat dissipation space is left between the heat dissipation fins 9;

[0025] The heat-conducting copper tube 10 is in a coil shape. Liquid inlet nozzles 11 and liquid return nozzles 12 are respectively arranged at both ends of the heat-conducting copper tube 10. The liquid inlet nozzles 11 and the liquid return nozzles 12 are respectively communicated with the liquid outlet and the recovery port of the coolant tank 3. The coolant tank 3 is a circulating liquid tank. The coolant is transported through the inside of the heat-conducting copper tube 10. The coolant is heated, evaporated and vaporized by the internal heat, bringing the heat from the inside to the outside, and is dissipated through the external heat dissipation assembly, so as to achieve an ideal heat dissipation effect and improve the service performance.

[0026] During actual use, the structure of the heat dissipation assembly is small, and the requirement for the installation space is low. It can be installed in a relatively narrow space for heat conduction. Through the heat dissipation assembly, it can be accurately fitted to the outside of the component that needs heat conduction and heat dissipation, which can effectively improve the heat conduction and heat dissipation effect, and the installation is more convenient and fast. Through the heat dissipation assembly, it can cooperate with the heat-conducting copper tube 10 to dissipate the heat conducted out by the heat dissipation assembly to the outside. The heat dissipation point is outside the controller chassis 1, and there is no need for the controller chassis 1 housing to bear the heat dissipation carrier anymore. The heat dissipation effect is stronger and it is more convenient to use. It can adapt to different application scenarios, increasing the adaptability.
