High-frequency charging module with good heat dissipating effect

Abstract

The invention discloses a high-frequency charging module with good heat dissipating effect which comprises a shell, a control unit and a power unit, wherein the control unit and the power unit are arranged in the shell; the control unit is arranged on one side in the shell; the power unit is arranged on the other side in the shell; the control unit is electrically connected with the power unit; a heat conductor is connected with the power unit; a heat dissipating device is arranged outside the shell; a heat exchange channel is arranged on the heat conductor; the two ends of the heat exchange channel are communicated with the radiating device through heat conduction devices. According to the invention, the control unit and the power unit are independently arranged, so that the heat of the power unit can be independently and effectively dissipated and the heat dissipating efficiency can be greatly increased; the heat exchange device is arranged outside the shell, so that the substances including liquid and dust in the outside environment can be prevented from entering the shell, the service life of the device can be prolonged and the high-frequency charging module has high progress significance and practical value.

Description

technical field [0001] The invention relates to a charging module, in particular to a high-frequency charging module which is easy to dissipate heat. Background technique [0002] In recent years, the use of electric vehicles has become more and more extensive. Electric vehicles rely on rechargeable batteries to provide power. When the equipment outputs large current and high voltage when working at full load, it is easy to cause the temperature of some components inside the module to rise sharply, and the heat cannot be fully dissipated, resulting in excessive temperature of the module, which may cause no output or reduced capacity output of the module, resulting in The rapid aging or failure of the module equipment requires cooling treatment. At present, there are mainly natural cooling methods, forced air cooling methods, and internal air-conditioning heat exchange methods to dissipate heat from the equipment. The main forced air cooling methods currently used are The he...

[0002] In recent years, the use of electric vehicles has become more and more extensive. Electric vehicles rely on rechargeable batteries to provide power. When the equipment outputs large current and high voltage when working at full load, it is easy to cause the temperature of some components inside the module to rise sharply, and the heat cannot be fully dissipated, resulting in excessive temperature of the module, which may cause no output or reduced capacity output of the module, resulting in The rapid aging or failure of the module equipment requires cooling treatment. At present, there are mainly natural cooling methods, forced air cooling methods, and internal air-conditioning heat exchange methods to dissipate heat from the equipment. The main forced air cooling methods currently used are The heat conductor is cooled by forced air through the fan installed in the housing, and the wind passes through the exhaust holes on the housing to discharge the heat to the outside of the charging cabinet, and finally exhausts the hot air from the cabinet to the outside of the cabinet through fan exhaust. External dust, liquid, corrosive gas and other substances can easily enter the housing through the exhaust holes on the housing, causing the module to malfunction

[0003] The control unit and power unit in all charging modules in the market are set up next to each other. However, the heating of the module is basically caused by the heating of the power unit, but the heat dissipation is performed on the control unit and the power unit at the same time, which greatly reduces the heat dissipation efficiency.
