Heat radiator

Technical Field

The utility model relates to a belong to electrical components heat dissipation technical field, specifically be a radiator.

Background

With the rapid development of science and technology, high heat flux devices are widely used in various aspects of national economy. The general principle of thermal design for high heat flux devices is to provide a path of thermal resistance as low as possible from the heat source to the environment in order to control the hot spot temperature to operate within a safe temperature range. As a class of high heat flux devices, the power of electronic equipment is increased year by year, the surface heat flux density of the electronic device is increased when the electronic device works, the thermal design requirement of a radiator is also stricter, and if a large amount of heat cannot be dissipated in time, the working frequency, the mechanical strength, the reliability and the like of the electronic equipment are seriously influenced.

Most of the existing radiators in the current market adopt columnar fins, and the radiators are usually pure cylindrical and polygonal. The polygonal bottom surface cylinder is most common in a square shape and a hexagon shape, and although different designs have some differences, the columnar surfaces of the polygonal bottom surface cylinder are all smooth straight surface structures, so that the heat dissipation area on the fins is limited to a certain extent, and the heat dissipation effect is poor; meanwhile, the forging and pressing molding is required due to the structural limitation, the manufacturing period is long, and the cost is high.

Therefore, there is a need to develop a heat sink with small volume and high heat dissipation power to meet the market demand. The heat radiation structure is a heat radiation structure with higher efficiency.

SUMMERY OF THE UTILITY MODEL

The technique that exists is not enough to the aforesaid, the utility model aims at providing a radiator, the better limited, the poor problem of radiating effect of fin heat radiating area of having solved, both shortened production cycle simultaneously, reduced manufacturing cost again.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a radiator, which comprises radiating fins and a bottom plate, wherein the radiating fins are arranged on the bottom plate and are integrally connected with the bottom plate; the radiating fin is additionally provided with a curved surface structure based on a pin-shaped fin structure, and can be directly obtained through an extrusion forming process and a machining process.

Preferably, the radiating fins are arranged in a column-shaped tower-shaped small dense-tooth structure.
