The present invention relates to a radiator, and more particularly to a fin-type radiator.

With the development of technology, the size of electronic products has become smaller, correspondingly the amount of heat generated in the unit space has increased, and higher demands for heat dissipation have been submitted, and heat sinks have become part of electronic products. It became an essential part. A regular radiator is mainly composed of a single base plate and a plurality of fin groups having heat conducting and radiating action, and the fin group has a plurality of fins arranged in an overlapping manner, and the radiator has an enhanced heat radiation effect. In order to do so, a heat pipe may be provided.

Specifically, a single fin is arranged on the base plate in which grooves are provided in advance, and a die is used. The fins were connected and fixed to the base plate by allowing the fins to be pressed and deformed to allow the fin roots to form an interference fit with the deformed grooves. In this process, not only was the groove processing complicated, but the gap between the fins was very small, making the groove pressing process with the mold inconvenient, taking a long time, and increasing the defect rate. Therefore, this method has certain advantages compared to the above-described soldering radiator, but there are many steps, inconvenience in processing, and there are still disadvantages of high cost, and the fin-shaped root of the fin The contact area between the base plate and the base plate was limited, which affected the heat transfer efficiency.
