Abstract

The utility model discloses a high-efficient heat tube spiral fin radiator, and relates to a radiator of an electronic device. The bottom part of the spiral fin of the radiator is provided with flanging with a certain width, and the spiral fin is evenly wound on the surface of a heat tube through the flanging. A plurality of spacer bars are arranged between the base and the heat tube, wherein one ends of the spacer rods are connected to the heat tube, and the other ends are fixed on the base. The high-efficient heat tube spiral fin radiator disclosed by the utility model is simple in structure and convenient in use, increases the contact area between the spiral fin and the heat tube, improves the rate of heat transfer of the spiral fin, prevents adjacent spiral fins from contacting with each other, and improves the radiating effect of the radiator greatly.

Description

High-efficiency heat pipe revolves the wing radiator

Technical field

The utility model relates to the heat abstractor of electronic device, is specifically related to a kind of heat pipe and revolves the wing radiator.

Background technology

Because heat-pipe radiator has that capacity of heat transmission is high, pyroconductivity is high, heat transfer rate is fast, light weight, characteristics such as the power consumption energy not, on the electric elements that are widely used for electronic product dispel the heat.Existing heat-pipe radiator generally includes heat pipe, pedestal and fin, pedestal is affixed on the electric elements table, heat pipe one end is fixed on the pedestal, the heat pipe surface wears some fin, because helical fin can enlarge the area of dissipation of heat pipe and extraneous air, beginning progressively adopts helical fin as fin in the industry, but present helical fin is to be spirally wound on the heat pipe, helical fin forms wire with the heat pipe surface and contacts, contact area is less, slow by the conduction of helical fin heat, cause radiator heat-dissipation efficient poor.In addition, the electric elements thermal discharge is larger, and heat-pipe radiator is in the heat radiation process, the helical fin on heat pipe surface expands with heat and contract with cold frequently, adjacent helical fin contact phenomena often occur, can cause the distortion of helical fin profile when serious, affect the radiating effect of whole radiator.

The utility model content

The purpose of this utility model provides a kind of high-efficiency heat pipe and revolves the wing radiator, solves the prior art helical fin and contacts the problem that causes radiating effect poor with little, the adjacent helical fin of heat pipe contact area.

The utility model mainly is comprised of pedestal, heat pipe and helical fin, heat pipe one end is fixed on the pedestal, the technical scheme that solves its technical problem employing is the flanging that the helical fin bottom has certain width, helical fin is wrapped on the heat pipe surface equably by its flanging, some spacer bars are set between pedestal and the heat pipe, spacer bar one end is connected on the heat pipe, and the other end is fixed on the pedestal.

The flanging width of above-mentioned helical fin is 1.5mm-2.5mm.

The beneficial effects of the utility model are simple in structure, easy to use, helical fin and heat pipe contact-making surface have the flanging of certain width, thereby the prior art helical fin contacted with the wire of heat pipe change planar contact into, greatly increased the contact area between helical fin and the heat pipe, improve the rate of heat transfer of helical fin, greatly improved the radiating effect of radiator; Some spacer bars are set simultaneously, thereby have effectively solved the problem that adjacent helical fin contact causes the profile distortion.

Description of drawings:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

Fig. 1 is structural representation of the present utility model.

1 pedestal, 2 heat pipes, 3 helical fins, 4 flangings, 5 spacer bars among the figure.
