Abstract

Technical Field
[0001] This utility model relates to the field of controller technology, specifically to a die-cast aluminum straight-barrel waterproof heat dissipation controller. Background Technology
[0002] A controller is a device or combination of devices used to automatically regulate the state of a system. It is widely used in industrial automation, robotics, electronic equipment and other fields. The controller housing is usually made of plastic, aluminum alloy or stainless steel, which has good protective performance and protects the internal circuits from the influence of the external environment.
[0003] However, traditional controllers have significant shortcomings in terms of heat dissipation, waterproofing, and structural strength. The small thermal contact area after the controller's base is fixed to the MOSFET results in low heat dissipation efficiency, high thermal resistance, and a high risk of device failure due to high temperatures. Insufficient sealing of the terminals and sockets allows rainwater or moisture to penetrate, causing short circuits. Furthermore, the separate base and side structure is prone to stress concentration, leading to insufficient overall structural strength. Therefore, there is an urgent need to design a controller housing with efficient heat dissipation, excellent waterproofing, and a high-strength structure. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 The present invention provides a die-cast aluminum straight-barrel waterproof heat dissipation controller, including: a base 1.
[0022] Among them, such as Figures 1-5 As shown, the top of the base 1 is integrally formed with a surrounding plate 2. The top of the surrounding plate 2 is fixedly connected with a cover 3. The bottom of the base 1 is provided with several heat dissipation ribs 13. The top of the heat dissipation ribs 13 is embedded with a heat dissipation step 9, and the heat dissipation step 9 is T-shaped. The controller is composed of the base 1, the surrounding plate 2 and the cover 3. The base 1 and the surrounding plate 2 are integrally die-cast. The surrounding plate 2 forms a closed cavity through the sealing fit between the base 1 and the cover 3. The heat dissipation step 9 is used to install the aluminum substrate. The heat dissipation step 9 and the several heat dissipation ribs 13 are in close contact with each other to increase the heat conduction efficiency and heat dissipation area.
[0023] Furthermore, refer to Figure 6 The heat dissipation step 9 is provided with a mounting groove 10, and the inner wall of the mounting groove 10 is coated with a thermally conductive silicone grease layer 12. The MOS transistor in the controller is mounted on an aluminum substrate, and the aluminum substrate can be fitted into the mounting groove 10. The thermally conductive silicone grease layer 12 fills the space between the mounting groove 10 and the aluminum substrate, thereby enhancing the heat conduction efficiency, reducing thermal resistance, and improving the overall heat dissipation performance.
[0024] In this embodiment, as Figures 1-4 As shown, the faceplate 3 is provided with a socket hole 7 and a terminal hole 6. The socket hole 7 is provided with a first sealing ring 4, and the terminal hole 6 is provided with an annular waterproof gasket 5. The top inner wall of the enclosure 2 is provided with a second sealing ring 11, which fits against the bottom of the faceplate 3.
[0025] The socket hole 7 and the terminal hole 6 are used for the through installation of the controller socket and terminal, respectively. Together with the first sealing ring 4 and the annular waterproof gasket 5, the sealing performance is improved and the waterproof performance is effectively enhanced. The second sealing ring 11 can improve the sealing effect between the cover 3 and the surrounding plate 2.
[0026] Furthermore, the outer wall of the enclosure 2 is provided with several linear grooves. The linear grooves can reduce the weight of the enclosure 2 and increase the surface area, thereby enhancing the overall natural heat dissipation effect of the enclosure 2.
[0027] like Figure 4As shown, two connecting plates 8 are symmetrically installed on the inner wall of the enclosure 2. The cover 3 is connected to the connecting plates 8 by bolts. The connecting plates 8 provide a stable connection point for the cover 3. The bolts can be used to fix the cover, which can achieve quick disassembly and assembly and structural stability.
[0028] Specifically, heat dissipation step 9 is a metal heat-conducting plate. The metal heat-conducting plate has good thermal conductivity and can quickly conduct the heat generated inside the controller to the surface.
[0029] Based on the above technical solution, the working steps of this solution are summarized as follows: The controller provided by this utility model consists of a base 1, a surrounding plate 2 and a face cover 3. The base 1 and the surrounding plate 2 are integrally die-cast. Through the sealing cooperation between the base 1 and the face cover 3, the surrounding plate 2 forms a closed cavity to achieve structural protection.
[0030] The socket hole 7 and the terminal hole 6 are used for the through installation of the controller's socket and terminal, respectively. Together with the first sealing ring 4 and the annular waterproof gasket 5, the sealing performance is improved, effectively enhancing the waterproof performance. The base 1 has a heat dissipation step 9 for easy installation of the aluminum substrate. The heat dissipation step 9 and several heat dissipation fins 13 fit together to increase the heat conduction efficiency and heat dissipation area, thereby improving the heat dissipation efficiency and ensuring the thermal stability of the controller during operation. This solves the problems of poor heat dissipation and water ingress short circuit in traditional controllers, and is suitable for high-power and high-protection scenarios such as electric vehicles and industrial motors.
