Problems solved by technology

[0002] Various electrical equipment and electrical sites have rated voltage and frequency requirements. In many workplaces, due to the lack of power distribution and transformation equipment, the voltage and frequency of the connected transmission end often do not match the electrical equipment that needs to be used. To use the power device, it is necessary to use a power conversion device to convert the output power of the power transmission terminal and then use it for electrical equipment. The power conversion device will generate heat when used, but the heat dissipation performance of the power conversion device currently used is not good, and the heat will accumulate during long-term use. It is prone to danger, and a power conversion device with good heat dissipation and easy movement is needed to solve this problem

Abstract

The invention discloses a power conversion device. The power conversion device comprises a device base. A protection casing body is arranged on the device base. A processor is arranged on one side of the protection casing body. One end of the protection casing body is provided with a liquid inlet, a liquid outlet and an inlet base. The other end of the protection casing body is provided with an outlet base. The inlet base and the outlet base are electrically connected with a conversion box arranged in the protection casing body. The lower part of the conversion box is connected with a slide base through a group of vertical damping springs. Both ends of the slide base are provided with lateral damping springs. A group of semiconductor cooling plates and a group of fans are arranged in the protection casing body. A serpentine heat exchange tube is arranged on the surface of the conversion box. The power conversion device has the advantages of easy and labor-saving movement, flexible positioning and reliable fixation, is provided with water cooling and air cooling, and has a good damping effect. The conversion box is prevented from being damaged by bumping. The service life of the device is prolonged. The failure rate is reduced.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a power conversion device. Background technique [0002] Various electrical equipment and electrical sites have rated voltage and frequency requirements. In many workplaces, due to the lack of power distribution and transformation equipment, the voltage and frequency of the connected transmission end often do not match the electrical equipment that needs to be used. To use the power device, it is necessary to use a power conversion device to convert the output power of the power transmission terminal and then use it for electrical equipment. The power conversion device will generate heat when used, but the heat dissipation performance of the power conversion device currently used is not good, and the heat will accumulate during long-term use. It is prone to danger, and a power conversion device with good heat dissipation and easy to move is needed to solve this problem. Contents ...
