Heat dissipation type electric control cabinet for rail transit

Abstract

The invention discloses a heat dissipation type electric control cabinet for rail transit, and belongs to the technical field of rail transit. According to the scheme, when an electric control cabinet body works, hot air generated in the electric control cabinet body is extracted through an air extraction fan and is exhausted upwards through an exhaust funnel and heat dissipation fins, waterproof breathable films in cooling boxes on the two sides move under the action of the air extraction fan, a stirring spring is pulled to deform, a stirring piece stirs the cooling liquid to flow, cold air emitted by the cooling liquid enters the electric control cabinet body from the large port of a compression pipe and then from the small port of the compression pipe to be supplemented, the cold air is compressed and dried, moisture in the cold air is removed, the temperature of the cold air is lowered, and then the temperature in the electric control cabinet body is lowered more effectively. In addition, a dustproof net plays a dustproof role, dust is prevented from being accumulated on the exhaust fan to affect work of the exhaust fan, the air flows upwards and drives the fan blades to rotate, a cleaning brush is enabled to brush the dustproof net, and the situation that the dustproof net is blocked and air circulation is affected due to dust accumulation is avoided.

Description

technical field [0001] The invention relates to the technical field of rail transit, and more specifically, relates to a heat dissipation electric control cabinet for rail transit. Background technique [0002] Rail transit refers to a type of transportation means or transportation system that operating vehicles need to run on specific tracks, usually including subways and railways, which have the characteristics of large transportation volume, fast speed, safety, punctuality, environmental protection, energy saving and land use. With the development of the times, rail transit is becoming more and more common. In rail transit, electric control cabinets are often used to control some circuits during the operation of rail transit to ensure the normal operation of rail transit. [0003] The electric control cabinet for rail transit in the prior art has poor heat dissipation effect, and the large amount of heat generated by it during work cannot be dissipated in a timely and ef...

Problems solved by technology

[0003] The electric control cabinet for rail transit in the prior art has poor heat dissipation effect, and the large amount of heat generated during its work cannot be dissipated in a timely and effective manner, resulting in an increase in its temperature and damage to it due to high temperature, thereby affecting its work, greatly reduce its working efficiency, for this reason, we propose a heat dissipation electric control cabinet for rail transit
