Abstract

The invention discloses a high-efficiency cooling sheet, which comprises a sheet body, round holes, circular arch punching holes, and square arch punching holes, wherein the sheet body is punched integrally to fabricate; multiple round holes are arranged on the sheet body; the edge of each round hole is turned for twice; a round groove is arranged above each round hole; the circular arch punching holes are arranged around each round hole; each square arch punching hole is arranged between each round hole and the adjacent transverse round hole; and two longitudinal sides of the sheet body are provided with corrugated turned edges, and the sheet is made of T2 copper or TP1 copper or L2 aluminum and arranged in a cooler cooling core group. The high-efficiency cooling sheet is a better cooling element, overcomes defects of the cooling area and heat exchange efficiency of the current cooler cooling element, and has the advantages of large cooling area, high cooling efficiency and corrosion resistance.

Description

technical field [0001] The invention relates to a cooling element in a cooler, in particular to a high-efficiency cooling fin used in the cooler to cool a core group. Background technique [0002] With the vigorous development of high technology, electronic devices are becoming increasingly intelligent and complex, the volume of electronic devices tends to be miniaturized, and the density per unit area is also getting higher and higher. The direct impact of this situation is that electronic devices generate more and more heat during operation. If there is no good heat dissipation method to remove the heat generated by electronic devices, these excessively high temperatures will cause electron ionization and thermal stress in electronic devices, resulting in reduced overall stability and shortened life of electronic devices. [0003] There are many kinds of cooling elements for air coolers, such as coiled spring cooling tubes, coiled fin cooling tubes, finned cooling tubes, ...
