Heat dissipation device for general electrical equipment

Abstract

The invention discloses a heat dissipation device for general electrical equipment. The heat dissipation device comprises: an outer cooling pipe and an inner cooling pipe, wherein the outer cooling pipe is fixedly connected to the top of the inner cooling pipe, outer cooling fan blades are rotatably arranged in the outer cooling pipe, and a mounting plate is fixedly connected to the surface of the inner cooling pipe; and an inner cooling assembly arranged in the inner cooling pipe and used for driving air in the electrical equipment to flow. The spiral positions of a water-cooling circulating pipe and an air circulating pipe are cooled through the outer cooling fan blades, air in the air circulating pipe exchanges heat with cooling liquid in a circulating cavity when passing through a communicating cavity, a second communicating hole and an air outlet hole, and finally returns into the electrical equipment, and the air is matched with inner cooling fan blades to rotate and revolve at the same time, so a spiral pipe and cooling fins can uniformly dissipate heat of air in the electrical equipment, and the air in the electrical equipment does not exchange with external air, so that the dust-free purpose can be achieved under the condition that heat dissipation is not affected.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for electric equipment, in particular to a heat dissipation device for general electric equipment. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical factor for the normal operation and transmission of electricity in a power plant is the electrical equipment. When dissipating heat from the electrical equipment, it is necessary to open holes on the surface and exchange the outside air with the high-temperature air in the electrical equipment to prevent heat dissipation. for cooling purposes. [0003] However, when the existing technology is actually used, when the electri...

Problems solved by technology

[0003] However, when the existing technology is actually used, when the electrical equipment is cooled, it is easy to cause dust to condense and settle around the electrical equipment, thereby destroying the insulation strength of the electrical equipment, and easily causing electrical breakdown and short circuit accidents during the gas operation process. , and some dust still accumulates in the electronic board, causing electrical malfunction, short circuit, etc., causing great harm to its safe operation
