Manufacturing method of radiator

Abstract

A method for manufacturing a radiator, comprising the following steps: a material preparation step, a positioning step, a punching step, a pressing and bending step, a cutting and riveting step, a rotating step, repeating the cutting and riveting step and rotating Steps, and a taking-out step; from the foregoing steps, the present invention continuously punches a metal strip on a processing machine to form heat dissipation fins, and sequentially cuts the heat dissipation fins from the metal strip, and inserts them in sequence into the slot of a metal substrate, and use two-way riveting to sequentially fix the cooling fins on the metal substrate, and then obtain the heat sink in an automated manner, which can provide rapid production and manufacturing, reduce redundant assembly processes, and increase production capacity. It can be greatly improved, and has the purpose of reducing manufacturing costs and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a radiator, in particular to a manufacturing method of a radiator for assembling heat dissipation fins on a metal substrate. Background technique [0002] At present, LEDs (light-emitting diodes) have gradually replaced traditional light sources in recent years, and the temperature of the LED modules in LED lighting fixtures must be controlled below about 80°C in order to convert electrical energy into light energy instead of heat energy, thereby making full use of the low-efficiency of LED lighting fixtures. Features of energy consumption and low heat. Therefore, LED lighting fixtures are equipped with a heat sink with a plurality of heat dissipation fins, so that the LED module can achieve rapid heat dissipation. [0003] However, common heat sinks on the market can be mainly divided into stacked heat sink fins and aluminum extruded heat sinks. The stacked heat dissipation fins connect multiple hea...

Problems solved by technology

The stacked heat dissipation fins connect multiple heat dissipation fins in sequence. However, the stacked heat dissipation fins can be connected head to tail to form a ring, and then soldered to a substrate to form a A heat sink, but after the soldering process, the soldering surface between the cooling fins and the substrate will increase the heat conduction resistance, which makes it difficult to meet the requirements of high heat conduction. At the same time, two processing times are required, which is quite labor-intensive and time-consuming, resulting in increased manufacturing costs.

In addition, for aluminum extruded heat sinks, the manufacturing process first produces a set of aluminum extruded molds. After the aluminum material is extruded, it must be cut according to the actual size of the heat dissipation fins, and then the cut burrs must be removed by grinding. Finally, the Anodizing is used to beautify the appearance, the overall manufacturing process is too complicated, the production capacity cannot be manufactured quickly, and the overall cost is high
