Embodiment Construction
[0018] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. Any solution obtained by equivalent replacement and conventional reasoning of the technical features of the technical solution of the present invention falls within the protection scope of the present invention. The fixed connection mentioned in the embodiment of the present invention, the fixed arrangement is welding, gluing, bolt and nut connection, screw connection and other known technical means known to those skilled in the art.
[0019] As shown in the figure, a high-performance aluminum plate radiator is characterized in that it includes a bottom plate and side plates, the number of the side plates is two, and the side plates are symmetrically distributed on both sides of the top of the bottom plate, and each of the side plates There are six heat dissipation folds arranged on the outside of t...

A high-performance aluminum plate heat dissipating device comprises a bottom plate and side plates. Six heat dissipating folding edges are arranged on the outer side of each side plate. Heat dissipating through holes are formed in the bottom plate. Heat dissipating mechanisms are arranged in the heat dissipating through holes. Each heat dissipating mechanism comprises an outer frame and a heat dissipating column. First heat dissipating strips are arranged on the inner side walls of the outer frames. Triangular protruding blocks are arranged at the two ends of the bottoms of the outer frames correspondingly. Arc-shaped grooves are formed in the junction of the heat dissipating columns and the outer frames. Second heat dissipating strips are arranged on the two sides of the heat dissipatingcolumns. Heat dissipating grooves are formed in the centers of the bottoms of the heat dissipating columns. The special heat dissipating side plates and the bottom plate are adopted, the heat dissipating folding edges on the side plates can well dissipate heat, the heat dissipating through holes are specially formed in the bottom plate, and thus heat exchanging of air is achieved advantageously; and by arranging the three special heat dissipating mechanisms, a ventilating channel is formed through the outer frames, the air flows through the interior of the ventilating channel, and the heat dissipating effect is good.
Description
technical field [0001] The invention relates to a heat sink, in particular to a high-performance aluminum plate heat sink. Background technique [0002] Most of the power radiators now use heat sink structure, no external power supply, natural cooling, most of them are made of aluminum alloy profiles, cut into the required size according to the size of the components. [0003] In the prior art, radiators for high-power power supplies are mostly used to dissipate heat by installing radiators or cooling fans on the relevant power devices of the circuit board of the power supply, and at the same time setting some vents on the chassis of the power supply to form air ducts to dissipate heat. The chassis of high-power power supplies are all made of sheet metal or extruded profiles. The structure is relatively simple and the heat dissipation effect is poor, which cannot really meet the needs of consumers and manufacturers. continue to improve Contents of the invention [0004] ...
