Structure for connecting heat dissipating fins and case

Abstract

The invention discloses a structure for connecting heat dissipating fins and a case. The structure comprises a plurality of heat dissipating fins connected to the heat dissipating case. The bottoms of the heat dissipating fins are embedded and cast into the heat dissipating case. Overflow-preventing bosses are arranged above the bottoms of the heat dissipating fins. The bottoms of the heat dissipating fins are embedded and cast into the heat dissipating case, and therefore the problem that glue bonding the heat dissipating fins is unbeneficial for heat conduction is solved and the heat dissipating efficiency is improved. The working procedures of manual bonding are reduced, the production efficiency is greatly improved, and the automation production can be achieved. The Overflow-preventing bosses arranged above the bottoms of the heat dissipating fins prevent metal liquid from overflowing from the two sides of each heat dissipating fin in the casting process and causing waste of materials. The overflow-preventing bosses extend out of the two ends of each heat dissipating fin, and therefore the metal liquid is further prevented from overflowing from the two ends of each heat dissipating fin and causing the waste of the materials.

Description

technical field [0001] The invention relates to the field of heat dissipation equipment, in particular to a connection structure between a heat dissipation fin and a housing. Background technique [0002] With the continuous development of electronic technology, the power of equipment is getting higher and higher, and the requirements for heat dissipation are getting higher and higher. In addition, outdoor electronic equipment needs waterproof, windproof and other protection. Outdoor electronic equipment often uses non-ferrous alloy casting shells as shells. The general design is die-casting shells. The inner space formed by the box cover is used to place printed circuit boards (PCB) or other equipment. , to play a protective role, and design cooling fins on the outside of the shell to help the equipment dissipate heat naturally. [0003] In the existing heat dissipation fins of electronic equipment, the aluminum casing is first cast, and then the heat dissipation fins are ...

AI Technical Summary

Problems solved by technology

This structure has the following disadvantages: 1. The heat dissipation fins are bonded to the heat dissipation shell with glue. Glue is a material with poor thermal conductivity. The glue between the shell and the fins is not conducive to heat conduction and reduces heat dissipation efficiency.

2. The heat dissipation fins need to wait for the heat dissipation shell of the casting to be bonded by manual operation. The production efficiency is low and the work intensity of the workers is high.

3. The heat dissipation fins are bonded to the aluminum shell, and the heat dissipation fins are easy to fall off, thereby reducing the heat dissipation capacity
