[0002] As the core component of variable frequency speed regulation systems, frequency converters (VFDs) are increasingly being used in industrial control. Their core components, electronic modules, feature high frequency, high voltage, and high speed, along with highly integrated circuits. As a converter, VFDs consume a certain amount of power during operation, rapidly increasing the heat generated per unit volume of the electronic device.

[0020] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a modular heat sink for an inverter, comprising an inverter body 1, an air guide duct 2 and heat dissipation blades 11. Grooves 12 are provided on both sides of the inverter body 1, and a plurality of air guide ducts 2 are provided, and are all arranged in the grooves 12. One end of the air guide duct 2 is bent inward and extends to the top of the inverter body 1 to form an air guide portion 4. The opposite surfaces of the air guide portion 4 are arranged in abutment with each other, and a heat dissipation channel with a "U"-shaped structure is formed between the air guide duct 2 and the inverter body 1. Half pipes 5 connected to the heat dissipation channel are installed on the air guide portion 4, and the half pipes 5 are combined to form an air injection pipe. A locking heat dissipation component is installed on the air inlet pipe 9. There are multiple heat dissipation blades 11, and they are all arranged inside the groove 12.

[0021] In this embodiment, a plurality of slide grooves 13 are vertically provided on the inner wall surface of the groove 12 facing the heat dissipating fins 11. The slide grooves 13 are expanded outward toward one end of the air guide portion 4 to form an inlet and outlet groove 14. A slider 15 is installed on one side of the heat dissipating fin 11 facing the slide groove 13. The slider 15 is slidably set in the slide groove 13. The cross-sections of the slider 15 and the slide groove 13 are both trapezoidal structures. Limiting plates are installed inside the air guide duct 2, and the limiting plates are set to contact the top surface of the heat dissipating fin 11.

[0022] In this embodiment, a plurality of limiting portions 3 are protruded from opposite surfaces of the air guide duct 2 , and the limiting portions 3 are all disposed in contact with the bottom surface of the inverter body 1 .

[0023] In this embodiment, the locked heat dissipation assembly includes a connecting pipe 6, a cooling fan 8, an air outlet pipe 7 and an air inlet pipe 9. The air outlet pipe 7 is installed on the air outlet end of the cooling fan 8. One end of the connecting pipe 6 is threadedly connected to the air outlet pipe 7, and the other end is threadedly connected to the air injection pipe. The air inlet pipe 9 is installed on the air inlet end of the cooling fan 8. A filter is installed in the opening on the outside of the air inlet pipe 9. The filter can effectively intercept dust and prevent the incoming air from carrying dust.

[0024] In this embodiment, a fixing bracket 10 is installed on the air outlet pipe 7 near the cooling fan 8. One end of the fixing bracket 10 extends to the back of the inverter body 1, and a plurality of straight slots are provided on the fixing bracket 10. Bolts can pass through the straight slots to fix the fixing bracket inside the device.

[0025] During installation, first insert the slider on the heat sink into the inlet and outlet slots, and then press down the heat sink to make the slider slide into the slot to complete the assembly of the heat sink.

[0026] After the above is completed, the air guide duct is inserted into the groove, the limiting portion below the air guide duct abuts against the bottom surface of the inverter body, and the air guide portion on the air guide duct abuts against the top surface of the inverter body, so as to complete the up and down positioning of the inverter body. Since the air guide duct is embedded in the groove, the inverter body can be completely positioned front and back through the cooperation with the groove, and the limiting plate on the air guide duct can press on the top surface of the heat dissipation fins, which can press the heat dissipation fins tightly and avoid the heat dissipation fins from moving upward and causing separation.

[0027] After the guide parts collide with each other, the half pipes can be combined to form the gas injection pipe. At this time, the connecting pipe can be rotated downward and threadedly connected to the outside of the gas injection pipe to complete the fixation of the half pipes and the inverter body.

[0028] On the contrary, after the connecting pipe is removed from the air injection pipe, the air guide duct can be directly taken out of the groove. After the air guide duct is lost, the inverter body can be directly disassembled. After the limit plate is lost, the slider on the heat dissipation fin can move upward to the inlet and outlet groove, and the heat dissipation fin can be disassembled outward along the inlet and outlet groove, which greatly increases the convenience.

[0029] When working, the cooling fan can be started. The wind generated by the cooling fan can be blown into the heat dissipation channel along the exhaust pipe, connecting pipe and air injection pipe. The wind can be concentrated through the heat dissipation channel so that the wind passes along the outer surface of the inverter body and the outer surface of the heat dissipation blades, which can more efficiently take away the heat from the inverter body to ensure the heat dissipation effect.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
