Abstract

The invention discloses a combined-type heat radiation structure used for a transformer. The structure comprises a vertical board. Through holes are uniformly arranged in the vertical board. Radiatingfins in snap joint with the vertical board are arranged in the through holes in a penetrating manner. The radiating fins are equipped with clamp grooves corresponding to the through holes. The overall heat radiation structure of a conventional transformer is changed. The through holes are uniformly arranged in the vertical board such that the radiating fins in snap joint with the vertical board are arranged in the through holes in the penetrating manner. The vertical board and the radiating fins are all copper aluminum alloy boards which hare low in cost and good in heat radiation performance. Manufacture process is optimized. Openings of the clamp grooves are equipped with chamfers in order to facilitate assembling in the late period. Polishing treatment comprises coarse grinding and precise grinding treatment such that burr and scraps on surfaces are processed clean, which is convenient for subsequent installation. Planeness errors of the vertical board and the radiating fins are nobigger than + / -0.01 mm so that assembly quality is increased. The combined-type heat radiation structure is simple in process so that the overall heat radiation area is increased. The heat radiationperformance is improved. The combined-type heat radiation structure shows great practicality.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a manufacturing process of a combined heat dissipation structure for a transformer. Background technique [0002] After 1870, with the widespread application of electricity, science and technology developed by leaps and bounds, and various new technologies and inventions emerged one after another, and were quickly applied to industrial production, greatly promoting economic development. With the continuous development of my country's economic construction and the acceleration of urbanization, electricity has become an indispensable part of people's production and life. At present, my country's main source of electricity is thermal power generation, which utilizes the heat energy generated during the combustion of solid, liquid, and gaseous fuels such as coal, oil, and natural gas, and converts it into electrical energy through power generation devices. With the rapid develo...
