Problems solved by technology

[0005] Although the above-mentioned prior art (Patent No. tw569660 of Taiwan Province of China) can achieve the purpose of simple manufacturing process and cost reduction, it is necessary to apply heavy pressure to both ends of the base in the manufacturing process to deform the groove and clamp the fin If the step of fins is applied to a radiator with a high height, the fins will be deflected because there is no supporting point on the top edge of the fins, resulting in poor uniformity and poor parallelism of the fins, especially the higher the height of the fins. When the temperature is high, the problem is more serious, which in turn causes the airflow to be uneven when the cooling device is in use, and the heat dissipation efficiency is reduced

Abstract

The invention discloses a manufacturing method of radiating device and auxiliary treating device with support device and radiating device with better leveling degree, which comprises the following steps: setting multiple locating grooves on the bottom brink of support device to chuck multiple fin apical margins; supplying support for device and base; pressing heavy pressure on two ends of base to clamp fin; making fin possess excellent flatness; producing even air-flow and excellent radiation efficiency for radiation device.

Description

technical field [0001] The invention relates to a heat dissipation device capable of producing better parallelism, an auxiliary jig and a manufacturing method of the heat dissipation device, especially a method that can provide good support for the top edge of the fins so that the fins will not be deflected and the fins The invention provides a cooling device, an auxiliary jig and a manufacturing method for the cooling device with good sheet uniformity and good parallelism, thereby making the air flow more uniform and the heat dissipation efficiency better. Background technique [0002] With the rapid development of the computer industry, the execution speed of heat sources such as chips and central processing units (CPU) is getting faster and faster, and the relative heat generation of heat sources is also getting higher and higher. In order to discharge the high temperature generated by heat sources in Externally, to make the heat source operate normally at the allowable t...
