Multi-angle radiation fin group forming method and radiator

Abstract

The invention discloses a multi-angle radiation fin group forming method and a radiator. The multi-angle radiation fin group forming method comprises steps that radiation fin blanks provided with inclined buckle parts are stretched to be inclined to acquire the arc-shaped radiation fin blanks; the radiation fin blanks are bent to acquire the radiation fins provided with buckled folded edges; the radiation fins provided with the buckled folded edges are buckled together to acquire the multi-angle radiation fin group. The multi-angle radiation fin group comprises a plurality of radiation fins, which are in a multi-angle connection by adopting buckling riveting blocks. Each of the radiation fins is provided with at least one heat pipe through hole. The radiator produced by adopting the multi-angle radiation fin group forming method is advantageous in that a certain included angle is arranged between each two radiation fin main bodies, and the included angle is also arranged between each two air outlets, and therefore the internal space of the radiator is increased, thermal convection effect is enhanced, heat conduction performance is improved by arranging the folded edges and the heat pipe through holes, and radiation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heat sinks, in particular to a forming method of a multi-angle heat sink group and a heat sink. Background technique [0002] The shape and size of each cooling fin in the existing heat sink are usually the same, and the cooling fins are generally arranged perpendicular to the base plate or at a fixed angle with the base plate. The general heat sink forming method is: A. Punching guide holes, punching guide holes on the surface of the conveyed material belt according to the preset distance; B. Cutting the material belt, cutting out the required material belt for each heat sink blank; C. Cutting the heat sink blank, according to the material, plate thickness and bending inner diameter of the heat sink, the bending expansion coefficient is obtained, and according to the bending expansion coefficient, the material belt required for each heat sink blank is cut to obtain the heat sink blank; D. The fastening ...
