[0036] As Figs. 1 to 4As shown, the present embodiment provides a vehicle-mounted refrigerator controller convenient for assembly and testing, comprising a housing 1, a circuit board 2, and a heat sink 3, a mounting opening 101 is arranged on the side of the housing 1, a circuit board card seat 102 is arranged on the inner side of the mounting opening 101, a buckle 103 is arranged at the front end of the mounting opening 101, the circuit board 2 and the heat sink 3 are fixedly sleeved between the circuit board card seat 102 and the buckle 103, an input terminal 201 is arranged on the top of the circuit board 2, an output connector 202 is connected to the side, a terminal slot 104 is arranged on the top of the housing 1 corresponding to the input terminal 201, and a connector clamping groove 105 is further arranged on the top of the housing 1, and the output connector 202 is detachably sleeved in the connector clamping groove 105.

[0037] In actual use, since the circuit board card seat 102 on the inner side of the mounting opening 101 and the buckle 103 at the front end cooperate with each other, the circuit board 2, the insulating heat-conducting pad 4 and the heat sink 3 are sequentially pressed into the mounting opening 101, so that the circuit board 2, the insulating heat-conducting pad 4 and the heat sink 3 are clamped between the circuit board card seat 102 and the buckle 103, and the assembly is completed without the need for additional workpieces such as screws for fixation, which is convenient to operate and high in production efficiency.

[0038] In addition, since the connector clamping groove 105 is arranged on the top of the housing 1, the output connector 202 can be sleeved in the connector clamping groove 105, so that the input terminal 201 of the circuit board 2 and the output connector 202 are positioned on the same plane, which facilitates quick docking of the input and output terminals when performing one-time FCT automatic testing and aging procedures and the like, and is high in testing speed.

[0039] The outer side of the heat sink 3 is provided with an inner recess clamping groove 301 corresponding to the buckle 103, and the outer side of the heat sink 3 is provided with a plurality of protruding ribs 302. In the present embodiment, the inner recess clamping groove 301 cooperates with the design of the buckle 103 hidden in the mounting opening 101, so that the heat sink 3 and the mounting opening 101 are kept on the same plane without protruding, thereby improving the assembly stability. The plurality of protruding ribs 302 can increase the contact area of the outer side of the heat sink 3 with the outside air, thereby improving the heat dissipation efficiency.

[0040] The inner side of the heat sink 3 is provided with an inwardly inclined chamfer edge 303 corresponding to the buckle 103. The chamfer edge 303 can avoid the relatively hard heat sink 3 made of metal materials with good heat conduction performance such as aluminum and copper from being pressed into the buckle 103 and damaging the buckle 103.

[0041] The circuit board 2 and the heat sink 3 are abutted and connected through the insulating heat-conducting pad 4. The insulating heat-conducting pad 4 can adopt commonly used insulating heat-conducting pad products on the market such as heat-conducting silicone rubber pads, so that the circuit board 2 and the heat sink 3 can be fully in contact and heat transfer.

[0042] The circuit board 2 and the side of the insulating heat-conducting pad 4 are provided with the empty gap 5 corresponding to the buckle 103. The empty gap 5 can reduce the resistance to be overcome when the circuit board 2 and the insulating heat-conducting pad 4 are pressed into the assembly opening 101, improve the assembly speed, and avoid damage to the components caused by forced assembly.

[0043] The bottom of the terminal slot 104 is provided with the isolation baffle 6, and the terminal through hole 601 is formed in the isolation baffle 6 corresponding to the input terminal 201. The isolation baffle 6 can isolate the circuit board 2 from the external environment while providing support for the input terminal 201, thereby improving the structural strength of the equipment.

[0044] The output connector 202 is connected to the circuit board 2 through the wire 203, and the wire material clamping groove 106 is arranged on the inner side of the connector clamping groove 105 corresponding to the wire 203. The wire material clamping groove 106 can clamp the output connector 202 and the wire 203 at the same time, thereby avoiding the wire 203 from hindering the output connector 202 from being clamped into the connector clamping groove 105.

[0045] The projection area of the circuit board 2 is smaller than the projection area of the heat dissipation fin 3, and the heat dissipation fin sleeve 7 is arranged in the frame of the assembly opening 101 corresponding to the side of the heat dissipation fin 3. The heat dissipation fin sleeve 7 can provide limiting support for the heat dissipation fin 3 from the inside, improve the structural strength, and avoid the heat dissipation fin 3 from being pressed too much during assembly, thereby preventing the circuit board 2 from being damaged.

[0046] The projection area of the outside of the heat dissipation fin 3 is equal to the area of the assembly opening 101. The heat dissipation fin 3 can block the assembly opening 101 as a cover, which is helpful to simplify the structure of the equipment and reduce the production cost.

[0047] The shell 1, the assembly opening 101, the circuit board clamping seat 102, the buckle 103, the terminal slot 104, and the connector clamping groove 105 are integrally formed injection molded parts. PA66+30% glass fiber, PA6+30% glass fiber, or other components can be used. The above-mentioned materials can be long-term temperature-resistant without deformation at 120-160°C. The power device such as the MOS tube running on the circuit board 2 is generally controlled below 120°C in long-term use, and the heat dissipation fin 3 and the power device are separated by the pcb and the insulating heat-conducting pad 4, so that the long-term use temperature actually conducted to the shell 1 will not exceed 100°C. Therefore, the shell 1 can be kept stable for a long time during equipment operation.

[0048] The above is a further detailed description of the utility model in combination with the specific preferred embodiments, and the specific implementation of the utility model cannot be limited to these descriptions. Any changes and modifications made within the scope of the application shall still fall within the scope of the utility model.
