Description

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.
Preferably, the heat dissipation fins are provided with a regular groove structure.
The beneficial effects of the utility model reside in that: the radiator in the utility model increases the heat radiation area while keeping the heat radiation advantage of the needle type radiator structure, and can completely meet the use requirements of the market; through the application of the columnar fin structure, the problems of limited fin radiating area and poor radiating effect are solved; and meanwhile, the restriction on the processing technology is reduced to a certain extent, so that the production period is shortened, and the production cost is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the embodiment, as shown in fig. 1, a heat sink includes heat dissipation fins 1 and a bottom plate 2, the heat dissipation fins 1 are disposed on the bottom plate 2 and integrally connected with the bottom plate 2, the connection mode reduces installation steps, and can be directly produced and molded, thereby improving production efficiency and reducing production cost.
Furthermore, the heat dissipation fin 1 is additionally provided with a curved surface structure based on a pin-shaped fin structure, and can be directly obtained through an extrusion molding process and a machining process, so that the effect of reducing the restriction of the machining process to a certain extent is achieved, the productivity is ensured, and the manufacturing cost is reduced.
Furthermore, the pin-shaped fin structure is an existing radiating fin structure, the surface of the pin-shaped fin structure is a smooth straight-surface structure, wind resistance can be reduced, radiating volume is reduced, and radiating rate is guaranteed.
Further, the embodiment, radiating fin 1 sets up to the little dense tooth structure of column form turriform, can guarantee that the fin further has bigger heat radiating area, possesses integrated into one piece's advantage simultaneously, is applicable to multiple heat dissipation field.
Furthermore, the heat dissipation fins 1 are provided with regular groove structures, and the regular groove structures are machined on the fins by adopting professional equipment, so that the weight of the fins can be reduced, the wind resistance can be reduced, and the heat dissipation performance can be further improved.
The radiator in the utility model keeps the structure heat dissipation advantage of the needle type radiator, increases the heat dissipation area, and can completely meet the use requirements of the market; through the application of the columnar fin structure, the problems of limited fin radiating area and poor radiating effect are solved; and meanwhile, the restriction on the processing technology is reduced to a certain extent, so that the production period is shortened, and the production cost is reduced.
