Description

Heat radiator

Technical Field

Background

At present, in a crimping type radiator, a section radiator and a shovel tooth radiator in the industry, radiating fins of the crimping type radiator, the section radiator and the shovel tooth radiator are distributed and arranged at equal intervals. According to the different distances between the radiating fins, the existing radiator can be divided into two types of forced air cooling radiating or natural air cooling radiating. However, the heat generated on the surface of the heat generating element is not uniformly distributed, that is, there may be a case where a part of the heat is accumulated more and another part of the heat is accumulated less. In this way, if the heat is radiated by the conventional forced air-cooled radiator, a good heat radiation effect can be obtained for a portion where a large amount of heat is accumulated, but a waste is caused for a portion where a small amount of heat is accumulated, but if the heat is radiated by the natural air-cooled radiator, the heat radiation of the portion where a large amount of heat is accumulated is insufficient, which causes damage to the heat generating element.
