[0002] With the continuous development of the power industry, the working power of the power conversion device is getting higher and higher. In order to ensure the normal operation of the power conversion device, it is necessary to ensure that the inductor connected to the power conversion device is kept working in a low temperature environment, which places higher and higher requirements on the heat dissipation of the inductor in the power conversion device.
[0003] In the prior art, the inductor and the power conversion device are stacked up and down and integrated in a container body, and due to the stacking of internal components, the liquid cooling system needs to occupy a large amount of internal space. The inductor is located at the air outlet below the power conversion device. The air outlet of the liquid cooling system enters from the air inlet of the power conversion device and dissipates the heat of the components in the power conversion device and then is discharged from the air outlet, and the inductor located below the air outlet is air-cooled and dissipated. This method of air-cooling the inductor has a high temperature of the wind discharged from the air outlet because the cold air has already air-cooled the components in the power conversion device, resulting in poor heat dissipation effect on the inductor located at the air outlet. The inductor works in a high-temperature environment for a long time, which affects the service life of the inductor. In addition, the vertical stacking of the inductor and the power conversion device results in a relatively high overall height, which is not convenient for the subsequent inspection and maintenance of the power conversion device and the inductor.

[0021] Reference Figure 1As shown, an air-cooled heat dissipation inductor device comprises: an inductor body 3, a supporting shell 1, an air-cooling plate 2, a heat dissipation fan 4 and a back-blowing dust removal system 5, wherein the inductor body 3 is accommodated in the supporting shell 1, one side of the supporting shell 1 is sealed and connected to one side of the electric energy conversion device, a docking boss is arranged on the lower end surface of the supporting shell 1, and a docking groove is arranged on the upper end surface of the air-cooling plate 2, the docking boss and the docking groove are arranged correspondingly, and the docking boss and the docking groove are sealed and docked, so that the supporting shell 1 and the air-cooling plate 2 are detachably connected through the docking boss and the docking groove, a first sealing groove is arranged on the periphery of the docking boss, a first sealing member is arranged in the first sealing groove, the first sealing member is sandwiched between the first sealing groove and the air-cooling plate 2, and a heat-conducting material is applied between the docking boss and the docking groove, and the heat-conducting material is used to fill the gap between the docking boss and the docking groove. By filling the heat-conducting material between the docking boss and the docking groove, the problem of air gap between the docking boss and the docking groove during processing or installation can be avoided, and the heat transfer efficiency between the inductor body 3 and the air-cooling plate 2 is improved. Specifically, the heat-conducting material is thermal grease, which is applied between the heating element and the heat dissipation facility to act as a heat transfer medium. The thermal grease has excellent thermal conductivity, and has excellent moisture-proof, dust-proof and corrosion-resistant properties. When the inductor body 3 needs to be cooled, the heat of the inductor body 3 is transferred to the supporting shell 1, and is transferred to the docking groove on the air-cooling plate 2 through the docking boss and the thermal grease. The circulating water inside the air-cooling plate 2 absorbs the heat of the docking groove to complete the heat dissipation of the inductor body 3, thereby greatly improving the heat dissipation efficiency of the inductor body 3.

The back-blowing dust removal system 5 includes: a controller, a fan forward operation contactor, and a fan reverse operation contactor, wherein the controller is a logic control unit, the positive power supply terminal and the negative power supply terminal of the controller are respectively connected to the positive and negative poles of the external power supply, the ground terminal of the controller is grounded, and the I1 terminal of the controller serves as the cooling fan start signal input terminal; the first coil terminal of the fan forward operation contactor is connected to the forward control signal output terminal of the controller through a group of normally closed contacts of the fan reverse operation contactor, and the second coil terminal of the fan forward operation contactor is connected to the negative pole of the external power supply; the first coil terminal of the fan reverse operation contactor is connected to the negative pole of the external power supply through a group of normally closed contacts of the fan forward operation contactor.
