[0001] The utility model relates to the technical field of low-voltage controllers, in particular to a heat dissipation structure and a low-voltage controller. Background Art

[0002] Low voltage controller refers to an electrical device that controls and protects electrical equipment in an electrical system where the AC voltage does not exceed 1000V and the DC voltage does not exceed 1500V. Its function is to protect electrical equipment and personal safety, effectively control the switching, starting and stopping of electrical equipment, and achieve the purpose of automatic control. When the evaporator fins are seriously dusted, the circulating air volume of the indoor unit is reduced, the refrigerant is insufficient, and the evaporator is frosted or frozen, the suction pressure may be too low.

[0003] The existing low-voltage controller will accumulate a lot of dust after working for a period of time, and the existing heat dissipation of the low-voltage controller is generally simply to cool the inside of the low-voltage controller through a fan. This heat dissipation method is not ideal in the high temperature environment in summer, resulting in the low-voltage controller being very likely to cause damage such as wire burst and short circuit after long-term use, and the service life is reduced. Therefore, a heat dissipation structure and a low-voltage controller are proposed to address the above problems. Utility Model Content

Embodiment 3

[0025] On the basis of the second embodiment, in order to achieve liquid cooling.

[0026] Furthermore, the limiting mechanism 5 includes a transmission rod 51 rotatably mounted in the middle of the inner cavity of the regulating box 4, a worm 52 is fixedly mounted on the left and right sides of the side wall of the transmission rod 51, a bidirectional screw 53 is also rotatably mounted on the left and right sides of the inner cavity of the regulating box 4, a worm wheel 54 is fixedly mounted in the middle of the side wall of the bidirectional screw 53, and a moving seat 55 is threadedly mounted on the front and rear sides of the side wall of the bidirectional screw 53;

[0027] The worm 52 is meshed with the worm wheel 54. A clamping motor 57 is fixedly installed on the upper end surface of the heat insulation seat 11 through a frame. The output shaft end of the clamping motor 57 passes through the adjustment box 4 and is fixedly connected to the transmission rod 51. A slide groove 41 is formed on the upper end surface of the adjustment box 4. The movable seat 55 slides in the inner cavity of the slide groove 41. A heat exchange plate 56 is fixedly installed on the upper end surface of the movable seat 55.

[0028] The liquid cooling mechanism 8 includes a heat exchange coil 81 fixedly mounted on the side wall of the heat exchange plate 56, and a coolant tank 82 is placed on both sides of the upper end face of the regulating box 4. The right end of the heat exchange coil 81 is connected to the coolant tank 82 through a liquid outlet pipe 83, and the left end of the heat exchange coil 81 is connected to the coolant tank 82 through a liquid inlet pipe 84.

Embodiment 4

[0029] A low voltage controller comprises the above heat dissipation structure.

[0030] In actual use, after the user places the capacitor 6 on the middle of the upper end surface of the adjustment box 4, the user starts the clamping motor 57 to rotate the transmission rod 51. Since the worm 52 is fixedly installed on the side wall of the transmission rod 51, the worm 52 will drive the worm wheel 54 to rotate the bidirectional screw 53. The two ends of the bidirectional screw 53 are respectively threadedly connected with the moving seat 55. Under the constraint of the slide groove 41 on the vertical direction of the moving seat 55, the moving seat 55 will drive the heat exchange plates 56 on the front and rear sides to move on the side wall of the adjustment box 4. As the heat exchange plates 56 on the front and rear sides approach each other, the heat exchange plates 56 can be firmly absorbed. Attached to the side wall of the capacitor 6, on the one hand, the device can clamp the capacitor 6, effectively reducing the shaking amplitude of the capacitor 6 when working or carrying. On the other hand, the heat exchange plate 56 can absorb the heat generated by the capacitor 6 when working. At this time, the user starts the heat dissipation fan 33 to discharge the high-temperature heat in the device housing 1 to the outside, and then let the cold air from the outside enter the inside of the device housing 1. At this time, the whole device can circulate the temperature of the inner cavity of the device housing 1 with the outside, thereby effectively reducing the temperature inside the device housing 1 and ensuring the working life of the electrical components inside the device housing 1.

[0031] When the entire device is working in high temperature weather in summer, the user can start the circulation pump 85 to allow the low-temperature coolant in the coolant tank 82 to enter the heat exchange coil 81 through the liquid inlet pipe 84. At this time, the entire device can realize the function of heat exchange for the heat exchange plate 56, and then can dissipate heat for the capacitor 6, thereby improving the heat dissipation effect of the entire device. Afterwards, the high-temperature coolant in the heat exchange coil 81 flows back to the coolant tank 82 through the liquid outlet pipe 83, so that the coolant can form a complete loop, thereby effectively improving the heat dissipation quality of the entire device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
