Abstract

The utility model relates to a forced radiating switch cabinet for wind-driven generating equipment. The forced radiating switch cabinet comprises a cabinet body, wherein a cylindrical air channel is vertically formed in the cabinet body; the upper end of the air channel is connected with an air outlet on the top of the cabinet body; a fan is arranged on an air outlet; an opening at the lower end of the air channel is positioned in the middle part of the cabinet body; a wall plate at the lower part of the cabinet body is provided with air inlet gratings; a bracket is arranged in front of the air channel; easily-heating elements are arranged on the front face of the bracket; and radiating fins are arranged on the back face of the bracket and are arranged in the air channel. The easily-heating elements can be arranged on the bracket in a centralized way, and forced radiating is performed through the radiating fins in the air channel, so that radiating effects of elements in the cabinet can be greatly enhanced; and in particular for highly heating elements such as a power unit of wind power equipment, running reliability is enhanced through forced radiating.

Description

Forced cooling switchgear

technical field

The utility model relates to a forced heat dissipation switch cabinet for wind power generation equipment.

Background technique

Ordinary switchgear usually does not have a forced cooling device, and only relies on the natural circulation of air in the cabinet to dissipate the heat generated during the operation of the components in the cabinet. Even if fans are used to dissipate heat, there is no dedicated air duct to focus on heat dissipation and cooling of key components. This makes it difficult to effectively dissipate the heat in the cabinet, and the temperature rise of the electronic components in the cabinet is relatively high during operation, which reduces their operational reliability and life.

Contents of the invention

The technical problem to be solved by the utility model is to provide a forced heat dissipation switchgear with good heat dissipation effect and high operation reliability.

The forced heat dissipation switch cabinet of the utility model includes a cabinet body, and a cylindrical air duct is vertically arranged in the cabinet body, and the upper end of the air duct is connected with the air outlet on the top of the cabinet body, and a fan is installed at the air outlet; The opening is located in the middle of the cabinet, and the wall panel at the lower part of the cabinet is provided with an air inlet grille; a bracket is arranged in front of the air duct, a heating element is installed on the front of the bracket, and a cooling fin is installed on the back of the bracket, and the cooling fin is placed on the windshield. in the way.

The lower section of the air duct is a semi-cylindrical structure with one side open, and the cooling fins are inserted into the air duct from the opening.

The utility model can centrally install the heat-generating elements on the bracket, and carry out forced heat dissipation through the cooling fins placed in the air duct, which can greatly improve the heat dissipation effect of the elements in the cabinet; especially for high-heating elements such as power units of wind power equipment, Through forced heat dissipation, its operational reliability is improved.
