Problems solved by technology

[0005] Since there are many heating elements in the inverter, it is necessary to provide a larger installation area at the bottom of the heating element chassis for the installation of various heating elements. The larger installation area at the bottom of the heating element chassis must be larger or more A radiator is used to conduct heat, which will not only make the cost of the entire inverter higher, but also make the entire inverter more bulky

Embodiment Construction

[0034] One of the cores of the present invention is to provide a heat dissipation system for a power converter, so as to effectively reduce the production cost of the power converter and the overall weight of the power converter while ensuring that the heat generated by the heating element is dissipated in time.

[0035] Another core of the present invention is to provide a power converter with the above heat dissipation system.

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] It should be noted that the essence of this solution has nothing to do with the type of the power converter. For the convenience of explanation, the embodiment of the present invention takes the inverter as an example for illustration, although only the inverter is given in this paper. embodiment, ...

Abstract

The invention discloses a cooling system of a power converter. The cooling system of the power converter comprises a heating element installation box, a cooling box and a cooling fan, wherein counter stands which are used for installation of various heating elements are arranged on the bottom surface of the heating element installation box, the tops of the counter stands are open, the top of the cooling box is fixedly connected with the bottom of the heating element installation box, the counter stands stretch into the cooling box, air inlets and air outlets are formed in the side walls of the cooling box, and the cooling fan is used for supplying air to the interior of the cooling box. The cooling system of the power converter has the advantages that it can be effectively guaranteed that heat of the heating elements is diffused rapidly; in addition, due to the fact that the counter stand structures are arranged in the cooling system of the power converter, the number or the weight of radiators can be effectively reduced, the production cost of the power converter can be effectively reduced, and the overall weight of the power converter can be effectively reduced. The invention further discloses a power converter provided with the cooling system.

Description

technical field [0001] The invention relates to the technical field of electronic device manufacture, in particular to a power converter and a cooling system thereof. Background technique [0002] The so-called power converters include rectifiers, choppers, inverters, AC controllers, and cycloconverters, which are widely used in various circuits. Various components in the power converter generate heat during operation, and these components are called heating elements. [0003] Taking the inverter as an example to illustrate, the heating element is usually located inside the inverter chassis, so the design of the chassis needs to consider transferring the heat generated by the heating element to the outside of the chassis as soon as possible. The inverters currently on the market The casing is generally composed of two casings, one of which is a heating element casing, the bottom of which is used to install various heating elements, and the other casing is a radiator casing,...
