[0028] 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.
[0029] Please see Figures 1-3 The present invention discloses a retarder controller structure, comprising a middle shell 1, a lower shell 2, and an upper shell 3. Cable interfaces 11 are fixedly installed at both ends of the middle shell 1. A control circuit board is installed inside the middle shell 1, and both ends of the control circuit board are connected to the cable interfaces 11. The lower shell 2 is installed on one side of the middle shell 1 and is bolted to the middle shell 1. The upper shell 3 is installed on the side of the middle shell 1 away from the lower shell 2 and is bolted to the middle shell 1. A portion of the lower shell 2 protrudes into the middle shell 1 to form a heat dissipation protrusion 4. The heat dissipation protrusion 4 protrudes into the middle shell 1 and abuts against the surface of the control chip on the control circuit board. A heat dissipation grille 41 is fixedly installed inside the heat dissipation protrusion 4.
[0030] In this way, the heat dissipation protrusion 4 is placed against the control chip, which facilitates the timely dissipation of heat from the control chip. Furthermore, a heat dissipation grille 41 is set inside the heat dissipation protrusion 4 to further improve the heat dissipation capacity.
[0031] In some feasible methods, the middle shell 1, the lower shell 2 and the upper shell 3 are shells set according to the shape and size of the control circuit board. The heat dissipation protrusion 4 and the lower shell 2 are integrally stamped or cast. The heat dissipation grille 41 is rectangular plate-shaped, which facilitates heat dissipation of the heat dissipation protrusion 4. The position of the heat dissipation protrusion 4 is set according to the position of the control circuit board chip and other components that need heat dissipation.
[0032] As one specific implementation of the retarder controller structure provided in the application, please refer to Figure 2 The lower shell 2 is recessed into the middle shell 1 to form a mounting groove 21. A Peltier 22 is fixedly installed in the mounting groove 21. The end face of the heat dissipation grille 41 is flush with the bottom of the mounting groove 21.
[0033] Overall, by setting up the Peltier 22, the heat dissipation grille 41 is partially exposed to the cooler side, thus accelerating the heat dissipation speed of the heat dissipation grille 41.
[0034] Furthermore, a cooling fan 23 is installed on the side of the Peltier 22 away from the middle shell 1.
[0035] It should be understood that by setting up the cooling fan 23, it is convenient for the high-temperature side of the Peltier 22 to dissipate heat.
[0036] In some feasible ways, the Peltier 22 is fixed or glued to the mounting groove 21 by bolts, and the high-temperature side of the Peltier 22 is provided with heat dissipation fins, and the cooling fan 23 is fixedly installed on the heat dissipation fins.
[0037] As one specific embodiment of the retarder controller structure provided in the application, during installation, the side of the heat dissipation protrusion 4 closest to the control circuit board is coated with a layer of silicone grease.
[0038] It should be understood that by setting a thermal grease layer, the four parts of the heat dissipation protrusion can make closer contact with the control chip, which facilitates heat dissipation.
[0039] Furthermore, a temperature sensor is installed on the control circuit board.
[0040] It should be understood that by setting a temperature sensor, it is convenient to monitor the temperature at the location of the control circuit board, and it is also possible to control the activation of components such as Peltier 22 at a suitable temperature.
[0041] As a specific embodiment of the retarder controller structure provided in the application, the lower shell 2 and the upper shell 3 are provided with sealing grooves 51 on the side near the middle shell 1, and sealing protrusions 52 are provided on both sides of the middle shell 1.
[0042] It should be understood that by setting the sealing groove 51 and the sealing protrusion 52, on the one hand, it is convenient to increase the sealing between the lower shell 2, the upper shell 3 and the middle shell 1. On the other hand, during installation, the heat dissipation protrusion 4 needs to contact the control chip. By setting the sealing groove 51 and the sealing protrusion 52, positioning is formed during installation, so that the heat dissipation protrusion 4 is aligned with the control chip.
[0043] Furthermore, a sealing strip is installed inside the sealing groove 51.
[0044] It should be understood that by setting a sealing strip, the sealing performance is further improved.
[0045] As another specific embodiment of the retarder controller structure provided in the application, please refer to Figure 3 The lower shell 2 is equipped with a support column 24, and the support column 24 is threadedly connected to a fixing bolt 241 for fixing the control circuit board. A control spring 242 is provided between the fixing bolt 241 and the control circuit board.
[0046] Depending on the specific application scenario, the control circuit board is mounted on the support column 24 and fixed with the fixing bolt 241. A control spring 242 is set at the fixing bolt 241 position. On the one hand, it is easy to maintain close contact between the control chip and the heat dissipation protrusion 4. On the other hand, it reduces the possibility of forming large pressure and damaging the circuit board.
