Heat dissipation device used in cooperation with power transformer

Abstract

A heat dissipation device used in cooperation with a power transformer is characterized in that an inner pipe and an outer pipe in a heat dissipation body are sleeved to form a plurality of A-type heat dissipation single bodies and B-type heat dissipation single bodies of an interlayer cavity structure, heat media in a transformer oil tank circulate in interlayer cavities, and heat dissipation fins or spiral heat dissipation fins are evenly distributed on the inner wall of the inner pipe and the outer wall of the outer pipe of each heat dissipation single body in the axial or radial direction;and the B-type heat dissipation single bodies and a confluence box form a heat dissipation unit, the heat dissipation unit and the flow collecting pipe form a heat dissipation combination body, the heat dissipation combination body can be divided into an adjustable heat dissipation center flow collecting type, a center flow collecting type and a peripheral flow collecting type according to the flow collecting type, and an unpowered air inducer is installed on the upper portion of the heat dissipation combination body for ventilation. The self-cooling effect and the heat dissipation efficiencyof the heat dissipation device are remarkably improved, the running temperature of the transformer is effectively reduced, the insulation and aging resistance of the transformer are protected, the heat dissipation device replaces or reduces fans, the heat dissipation device is an effective scheme for realizing energy conservation, and meanwhile, the manufacturing cost of the current heat dissipation device is also reduced.

Description

technical field [0001] The invention belongs to the field of processing, and relates to a cooling device used in conjunction with a power transformer. Background technique [0002] At present, the design and manufacture of power transformers have entered the stage of high-end and high-quality development. The supporting heat dissipation devices such as fin radiators and strong oil air coolers have not achieved new technological breakthroughs and innovations in the industry for decades. Its high manufacturing cost and low heat dissipation performance have become one of the main bottlenecks in the transformer industry. The industry has made some new technical solutions for this, such as retrieval 1, CN201110410625.1 High-frequency water-cooled transformer based on aluminum profile radiator, transformer secondary The winding and the center tap terminal are fixed on the aluminum radiator through the copper sleeve and the manifold. However, the defect of this scheme is poor stre...
