[0030] The present invention will be further described below in conjunction with the accompanying drawings: Example

[0031] See attached Figures 1 to 6 As shown: A controller 1 with a heat dissipation structure comprises: a front housing 10 with an opening at the rear end, a main control board 11 connected to the opening of the front housing 10 and provided with a plurality of control elements with easy heat release on its rear end surface, a power board 12 provided at the rear end of the main control board 11 and located on the side of the control elements, and a rear housing cover 13 with an opening at the front end for cooperating with the front housing 10 to surround the main control board 11 and the power board 12, wherein a heat dissipation panel 100 is provided at the rear end of the main control board 11, and the front end surface of the heat dissipation panel 100 is connected to the plurality of control elements The rear end surface of the heat dissipation panel 100 is fitted on the rear end surface thereof, a plurality of fins 101 are evenly arranged on the rear end surface thereof along the height direction, and a mounting frame 102 is arranged at the front end of the power board 12, the mounting frame 102 is connected to the heat dissipation panel 100, so that the height of the power board 12 is higher than the height of the fins 101, an air guide channel 103 is opened in the mounting frame 102 along the height of the heat dissipation panel 100, and air guide grilles 104 are opened at the upper end and the lower end of the rear shell cover 13, and the air guide grille 104 is communicated with the air guide channel 103 and the gap channel between two adjacent fins 101.

[0032] The front housing 10 has an opening at the rear end for accommodating a main control board 11 and a power board 12. The main control board 11 is an important control component of the entire controller 1 and is connected to the opening of the front housing 10. The rear end surface of the main control board 11 is provided with a plurality of control elements (chips) that are easy to release heat energy. The power board 12 is used to provide power to the main control board 11. A mounting frame 102 is provided at the front end of the power board 12. The mounting frame 102 is connected to the heat dissipation panel 100. The front end of the rear housing cover 13 has an opening. The rear housing cover 13 is used to cooperate with the front housing 10 to surround the main control board 11 and the power board 12 in the opening to play a protective role. In this embodiment, the upper and lower ends of the rear housing cover 13 are connected. Wind guide grilles 104 are provided at the corresponding positions, the heat dissipation panel 100 is provided at the rear end of the main control board 11, the front end surface of the heat dissipation panel 100 is in contact with the rear end surface of the control element, and when the control element generates heat, the heat is transferred to the fins 101, and the heat is dissipated through the evenly arranged fins 101, and the air guide channel 103 is provided in the mounting frame 102 on the side of the fins 101, and the gap channel between the air guide channel 103 and the fins 101 is connected, and the design of the air guide channel 103 and the air guide grille 104 forms a good air circulation path, so that the design effectively improves the heat dissipation capacity of the main control board 11 and the power board 12, and avoids damage to the controller 1 due to overheating.

[0033] Preferably, if Figure 2 , Figure 3 and Figure 5 As shown, the rear shell cover 13 has a first storage slot 105 and a second storage slot 106 connected to the first storage slot 105 in the opening, and the first storage slot 105 and the second storage slot 106 are provided with wind guide grilles 104 on the end surfaces away from each other in the height direction of the rear shell cover 13, the fin 101 is located in the first storage slot 105, and the mounting frame 102 and the power board 12 are located in the second storage slot 106.

[0034] The first storage slot 105 and the second storage slot 106 are arranged in the height direction inside the rear shell cover 13, and the two storage slots are connected to each other. The first storage slot 105 is mainly used to accommodate the fins 101 on the heat dissipation panel 100, and its rear end length is relatively long to ensure that the fins 101 can be fully covered and supported, thereby ensuring the effective operation of the heat dissipation panel 100. The second storage slot 106 is located below the first storage slot 105 and is connected thereto, and is mainly used to place the mounting frame 102 and the power board 12. Since the power board 12 requires a certain space to install the electronic components thereon, the design of the second storage slot 106 is relatively compact, and its rear end length is relatively short, so as to leave enough space for other components. An air guide grille 104 is arranged on the end surface away from each other between the first storage slot 105 and the second storage slot 106. This design not only helps to introduce cold air into the heat dissipation area, but also guides hot air to be discharged from the controller 1, thereby improving the air circulation efficiency and enhancing the heat dissipation performance of the entire system.

[0035] Furthermore, if Figures 2 to 4 As shown, a storage element 107 is provided at the rear end of the power board 12, the bottom depth of the second storage groove 106 is deeper than the bottom depth of the first storage groove 105, the storage element 107 is located in the second storage groove 106, and a first heat dissipation grille 108 is opened on the bottom wall of the second storage groove 106, and the first heat dissipation grille 108 is connected to the air guide grille 104.

[0036] A first heat dissipation grille 108 is designed on the bottom wall of the second storage slot 106. The grille is interconnected with the air guide grilles 104 at the upper and lower ends of the rear shell cover 13, forming an efficient air circulation system. When the outside cold air enters the controller 1 through the air guide grille 104, a part of the air will be directed to the area where the storage element 107 is located, and the heat generated by it will be taken away through the first heat dissipation grille 108. In this way, even in a high-intensity working environment, the storage element 107 can be maintained at a suitable working temperature, thereby improving the reliability and stability of the entire controller 1, optimizing thermal management, and reducing the risk of overheating.

[0037] Preferably, if Figures 2 to 6 As shown, the periphery of the heat dissipation panel 100 is bent and extends toward the front end direction of the main control board 11, so that the main control board 11 is semi-surrounded by the heat dissipation panel 100, and the front shell 10 and the rear shell cover 13 press the heat dissipation panel 100 tightly.

[0038] The semi-enclosed structure of the heat dissipation panel 100 enables it to fit more closely to the surface of the main control board 11, especially those key areas that are prone to generate heat. When the control elements on the main control board 11 are working, the heat generated can be quickly transferred to the heat dissipation panel 100 and quickly dissipated through the fins 101 on the heat dissipation panel 100. At the same time, the periphery of the heat dissipation panel 100 and the front end of the main control board 11 form a closed space, which helps to reduce the possibility of heat diffusion to other non-heat dissipation areas. As one of the core components of the entire heat dissipation system, the design details of the heat dissipation panel 100 are crucial to achieving efficient thermal management. Specifically, the periphery of the heat dissipation panel 100 is carefully designed, bent, and extends toward the front end of the main control board 11. This design enables the heat dissipation panel 100 to surround the main control board 11 in a semi-enclosed shape to form a close contact surface, thereby enhancing the effect of heat conduction. In addition, this design of the heat dissipation panel 100 also increases the contact area between it and the front shell 10 and the rear shell cover 13. When the front housing 10 and the rear housing cover 13 are closed, they hold the heat dissipation panel 100 tightly against each other, ensuring that the heat dissipation panel 100 is fixed in position inside the entire controller 1. This structure not only improves the heat dissipation efficiency, but also enhances the mechanical stability of the entire device, preventing the heat dissipation panel 100 from shifting due to vibration or other external forces, thereby affecting the heat dissipation effect.

[0039] Preferably, if Figure 2 , Figure 3 and Figure 6 As shown, a first abutment portion 109 is provided at the front end of the periphery of the heat dissipation panel 100, and a second abutment portion 119 is provided at the rear end, a first limiting portion 110 is provided in the opening of the front shell 10, and a second limiting portion 120 is provided at the opening of the rear shell cover 13; when the front shell 10 and the rear shell cover 13 surround the main control board 11 and the power board 12, the heat dissipation panel 100 and the second limiting portion 120 penetrate into the opening of the front shell 10, the first abutment portion 109 abuts against the first limiting portion 110, and the second abutment portion 119 abuts against the second limiting portion 120.

[0040] The front end of the periphery of the heat dissipation panel 100 is provided with a first abutment portion 109, and the rear end is provided with a second abutment portion 119. This design is intended to ensure that the heat dissipation panel 100 can maintain a fixed position inside the controller 1 to prevent displacement caused by external vibration or other mechanical stress. At the same time, a first limiting portion 110 is provided in the opening of the front shell 10, and a second limiting portion 120 is provided at the opening of the rear shell cover 13. These limiting portions cooperate with the abutment portions on the heat dissipation panel 100 to form a stable fixed structure. The heat dissipation panel 100 fits tightly with the main control board 11, and the first abutment portion 109 and the second abutment portion 119 cooperate with the limiting portions to further enhance the contact area and pressure between the heat dissipation panel 100 and the main control board 11, thereby improving the heat transfer efficiency. At the same time, the fixation of the heat dissipation panel 100 also ensures that the fins 101 thereon can work normally and will not affect the heat dissipation performance due to displacement.

[0041] Preferably, if Figure 2 , Figure 3 and Figure 6 As shown, the opening size of the rear end of the front shell 10 is larger than the size of the heat dissipation panel 100 and the rear shell cover 13, and there is a gap between the periphery of the heat dissipation panel 100 and the second limiting portion 120 and the side wall of the opening formed by the rear end of the front shell 10.

[0042] The opening size at the rear end of the front shell 10 is designed to be larger than the size of the heat dissipation panel 100 and the rear shell cover 13, so that a gap is formed between the periphery of the heat dissipation panel 100 and the side wall of the opening formed by the second limiting portion 120 and the rear end of the front shell 10. The gap between the periphery of the heat dissipation panel 100 and the side wall of the front shell 10 provides an additional circulation path for cold air, which helps to enhance the heat dissipation effect of the entire system. By increasing the air circulation path, more heat can be taken away, thereby reducing the operating temperature of the main control board 11 and the power board 12. This design not only ensures the fixation of the heat dissipation panel 100, but also does not affect the circulation of air, thereby achieving dual optimization of structural stability and heat dissipation effect. The larger opening size makes the installation of the heat dissipation panel 100 and the rear shell cover 13 easier and reduces the difficulty of assembly.

[0043] Furthermore, if Figure 2 and Figure 3 As shown, abutment portions are provided at the periphery of the heat dissipation panel 100, and a limiting portion is provided at the opening of the rear shell cover 13; when the fin 101 extends into the first storage slot 105, the mounting frame 102 and the power board 12 extend into the second storage slot 106, the abutment portions are in contact with the limiting portion.

[0044] The periphery of the heat dissipation panel 100 is provided with an outwardly protruding abutting portion, and the opening of the rear shell cover 13 is provided with a limiting portion matching the abutting portion. When the fin 101 is extended into the first storage groove 105, the mounting frame 102 and the power board 12 are extended into the second storage groove 106, the abutting portion is in contact with the limiting portion, thereby ensuring the stability and safety of the internal components of the controller 1.

[0045] Furthermore, if Figures 2 to 4 As shown, the mounting frame 102 has a first mounting portion 111 and a second mounting portion 112, the first mounting portion 111 is connected to a support frame 113, and an air guide channel 103 is formed in the support frame 113; the second mounting portion 112 is provided with a through slot 114 on the end surface close to the circuit board, the power board 12 is connected to the mounting frame 102 by bolts, and a power module 115 is arranged on the front end surface of the power module 115, the power module 115 is installed in the through slot 114 and is located at the end of the air guide channel 103 away from the fin 101.

[0046] The first mounting portion 111 is connected to a support frame 113, and the above-mentioned air guide channel 103 is formed inside the support frame 113. A through slot 114 is formed on the end surface of the second mounting portion 112 close to the circuit board. A protective cover is installed on the power board 12, and the protective cover is connected to the mounting frame 102 by bolts, so that the power module 115 is installed in the through slot 114. The support frame 113 improves the strength and stability of the overall structure. The design of the through slot 114 ensures that the power module 115 has heat dissipation space, and the wind flowing into the air guide channel 103 can also pass through the power module 115 to achieve heat dissipation.

[0047] Preferably, if Figure 1 and Figure 6 As shown, a display module 116 is disposed on the front housing 10, and the display module 116 is electrically connected to the power board 12. A plurality of second heat dissipation grilles 117 are provided around the front housing 10 located at the display module 116, and the plurality of second heat dissipation grilles 117 are interconnected with the gap.

[0048] The display module 116 is arranged on the front shell 10 and electrically connected to the power board 12. A plurality of second heat dissipation grilles 117 are arranged on the front shell 10. The design of the second heat dissipation grilles 117 ensures that the display module 116 will not overheat, thereby extending its service life and improving the reliability and durability of the controller 1.

[0049] A plurality of second heat dissipation grilles 117 are provided around the display module 116 on the front housing 10. The number and position of these heat dissipation grilles are carefully designed to ensure that air can flow into the controller 1 from multiple directions, thereby extending its service life and improving the reliability and durability of the controller 1. The second heat dissipation grilles 117 are interconnected with the gap between the rear open side wall of the front housing 10 and the periphery of the heat dissipation panel 100, forming an effective air circulation path. This design not only helps to reduce the temperature provided by the display module 116, but also assists the heat dissipation panel 100 in cooling, thereby ensuring the long-term stable operation of the controller 1.

[0051] The air compressor 3 is arranged on a pair of air tanks 2, and the pair of air tanks 2 are used to store the air compressed by the air compressor 3. The controller 1 is independent of the outside of the air compressor 3 and is installed on the pair of air tanks 2. The main control board 11 is electrically connected to the motor in the air compressor 3. This design not only improves the heat dissipation efficiency and reduces the failure rate of the controller 1 due to overheating, but also facilitates the maintenance, replacement or upgrade of the controller 1.
