Abstract

An oval tube type efficient cooling fin comprises a fin body, oval holes, annular arch-bridge punched holes and square arch-bridge punched holes. The fin body is integrally formed in a punched mode, the multiple oval holes are formed in the fin body, each oval hole is provided with two oval flanges, oval grooves are formed above the oval holes, the annular arch-bridge punched holes are formed around the oval holes, the square arch-bridge punched holes are formed between the oval holes and the adjacent oval holes, and the fin body is provided with corrugated folded edges in the longitudinal direction, made of T2 copper or TP1 copper or L2 aluminum and installed in a cooling core set of a cooler to be used. The oval tube type efficient cooling fin is integrally formed in the punched mode and has the largest cooling surface, the best cooling effect and the lowest wind drag pressure drop compared with products of the same industry.

Description

technical field [0001] The invention relates to a cooling element in an air cooler, in particular to an elliptical tube type high-efficiency cooling fin with high heat exchange efficiency, large heat dissipation area and reduced wind resistance pressure. Background technique [0002] The electronics industry is becoming the largest industry in the 21st century, and the level and scale of the electronics industry have become one of the important symbols to measure a country's comprehensive national strength. By 2004, the sales revenue of my country's electronic information industry reached 2.65 trillion yuan, contributing 13.9% more to GDP growth. In 2010, the sales revenue of the whole industry reached 7.8 trillion yuan, a year-on-year increase of 29.5%, accounting for about 7% of the national GDP. [0003] Today's electronic industry is on the road of rapid development, and electronic equipment has a trend of high speed, high density and miniaturization. With the increasi...
