Problems solved by technology
[0008] In the absence of a fan, the existing power electronic equipment uses natural convection to dissipate the heat of the radiator, so there is a problem of low heat dissipation efficiency
[0009] In addition, in the case of installing a fan to improve heat dissipation efficiency, although the heat dissipation efficiency can be improved, the main inlet hole and the main outlet hole are always open, so there are external air that continues to circulate regardless of temperature, and external foreign objects Problems flowing into the inside of the inverter

The present invention relates to a power electronic device with an automatic ventilation module, comprising: an enclosure in which a heating component is accommodated and which forms an exterior; and an automatic ventilation module, installed on one side of the enclosure, for opening and closing a part of the enclosure according to the temperature of the heating component, wherein the automatic ventilation module comprises: a driving unit, installed on one side of the inside of the enclosure, for generating power; a connection unit for transmitting the power generated by the driving unit; a ventilation unit for receiving the power from the connection unit and provided with a front plate for opening and closing a part of the enclosure; a temperature sensor, installed inside the enclosure, for measuring the temperature of the inside of the enclosure; and a control unit for controlling the driving unit on the basis of a measured value of the temperature sensor so as to adjust the degree of opening and closing of the front plate.
Description
technical field [0001] The invention relates to a power electronic device with an automatic ventilation module that detects temperature and automatically dissipates heat according to the temperature of the power electronic device. Background technique [0002] Generally, industrial power electronic equipment is used outdoors or indoors in a form in which main components and heat dissipation structures are installed inside the casing. The industrial power electronic equipment may be, for example, a power conversion device such as an inverter. Industrial power electronic equipment such as inverters often discharge high-temperature heat, so there is a ventilation structure for heat dissipation. [0003] figure 1 It shows an example of a conventional heat radiation structure of an electronic device. figure 2 is showing figure 1 Side view of the cooling structure of a power electronics device. [0004] Such as figure 1 As shown, the existing power electronic device 1 is an...
