Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0019] Such as image 3 and Figure 4 As shown, the radiator of the present invention includes a plurality of radiating fins 10 combined together, and each radiating fin 10 includes a body 12 and two folded edges 14, and the two folded edges 14 are perpendicular to the two opposite sides of the body 12 respectively. The main body 12 is bent in the same direction, and a slot 17 is provided inside the junction of each folded edge 14 and the main body 12 , and the slot 17 is disposed at a middle position of the corresponding folded edge 14 . The outer edge of the folded edge 14 corresponds to the card 16 that extends outward by a width from the position of the slot 17 and fits into the slot 17 , and the front edge of the card 16 forms an arc edge. The joint portion of the card 16 and the folded edge 14 forms an abutment portion 160 that...

Abstract

The invention relates to a heat radiator, which comprises several combined heat radiation wings, which each one comprises a main body and at least one folded edge on the side edge of said main body. Before assembly, the folded edge of one heat radiation wing extends to a card to another nearby radiation wing; the outer side of said folded edge has a projection at the part relative to the car; the main body of another heat radiation wing has a slot for inserting said card; after assembly, the combination part of said card and the folded edge are bended to the inner side of another heat radiation wing to form a support part which is supported with the main body of another heat radiation wing. The heat radiation wings of said invention have matched cards and projections, via the deformation of card to support another heat radiation wing, with stable combination and simple producing pocess.

Description

【Technical field】 [0001] The invention relates to electronic components, in particular to a radiator for heat dissipation of electronic components and a manufacturing method thereof. 【Background technique】 [0002] With the continuous development of electronic technology, the heat generated per unit volume of electronic components increases accordingly. However, due to the limitation of mechanical processing, the traditional aluminum extruded and die-cast radiators have limited heat dissipation area, and the area for exchanging temperature with the surrounding air is not large. The device no longer meets the heat dissipation requirements of current electronics manufacturers. [0003] Therefore, the industry improves the traditional heat sink to increase the overall heat dissipation area of ​​the heat sink. As a result, a combined heat sink consisting of several metal heat dissipation fins is produced, such as figure 1 In the heat sink group shown, a long folded edge 104 i...
