Abstract

The utility model discloses a cooling fin which comprises a main body. A plurality of sealed heat-conduction pipes are disposed inside the main body and arranged in parallel inside the main body. The heat-conduction pipes contain working mediums. According to the the utility model, a conventional cooling pin is combined with the heat-conduction pipes, and the heat-conduction pipes are disposed inside the cooling fin, and the heat-conduction pipes contain the working mediums. When the heat-conduction pipes are heated, the working mediums inside the heat-conduction pipes are converted from a liquid state into a gaseous state and absorb energy, so as to achieve the heat-dissipation effect. Compared with a heat-dissipation method by utilizing the materials of the cooling fin or through enlarging a heat-dissipation area, the heat-dissipation method provided by the utility model has a higher speed of heat dissipation and a better effect of heat dissipation.

Description

Fin

Technical field

The utility model relates to heat abstractor field, particularly a kind of fin.

Background technology

Fin is a kind of being usually used in to the easy device of heat-generating electronic elements heat radiation in electrical equipment, tabular, the sheet of how being made by aluminium alloy, brass or bronze or splintery etc.To use sizable fin as cpu central processing unit in computer, power supply pipe in television set, line pipe, the power tube in amplifirer all will use fin.Fin kind on market is various, mainly strengthens radiating effect by selecting good heat conducting material or increasing area of dissipation.In addition, how further to improve the radiating effect of fin, become industry urgent problem.

The utility model content

The purpose of this utility model is to provide a kind of novel fin.

According to one side of the present utility model, a kind of fin is provided, comprise main body, be provided with a plurality of airtight heat pipes in main body, heat pipe is arranged in parallel within body interior, is filled with working medium in heat pipe.

In some embodiments, main body and heat pipe are one-body molded.Integrated structure is saved operation, and stabilized structure.

In some embodiments, the metal master that main body is aluminium matter, copper, silver or alloy material is made.These material thermal conduction effects are good, are widely used in field of radiating.

The beneficial effects of the utility model: fin of the present utility model combines traditional fin with heat pipe, and heat pipe is set in fin, is filled with working medium in heat pipe.After heat pipe was heated, the working medium in heat pipe was converted into gaseous state from liquid state, and absorbed heat, reached the effect of heat radiation.The mode of this heat radiation, with the radiating mode that utilizes the material of fin own or increasing heat radiation area, radiating rate is faster relatively, and radiating effect is better.

Description of drawings

Fig. 1 is the overall schematic of the fin of a kind of execution mode of the present utility model.

Fig. 2 is that the fin of Fig. 1 is along the cutaway view of dotted line intercepting gained.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 and Fig. 2 have schematically shown the fin according to a kind of execution mode of the present utility model.

As shown in Figure 1 and Figure 2, fin comprises main body 1, is provided with a plurality of airtight heat pipes 101 in main body 1, and heat pipe 101 is arranged in parallel within main body 1 inside, is filled with working medium in heat pipe 101.Main body 1 is one-body molded with heat pipe 101.After heat pipe 101 is packed into working medium, under the dustless environment of vacuum, that the two ends of heat pipe 101 are airtight.

The beneficial effects of the utility model: fin of the present utility model combines traditional fin with heat pipe, and heat pipe 101 is set in fin, is filled with working medium in heat pipe 101.After heat pipe 101 was heated, the working medium in heat pipe 101 was converted into gaseous state from liquid state, and absorbed heat, reached the effect of heat radiation; Integrated structure is saved operation, and stabilized structure; Main body 1 is the metal master of aluminium matter, and the aluminum material thermal conduction effect is good, and light weight is widely used in field of radiating.The mode of this heat radiation, with the radiating mode that utilizes the material of fin own or increasing heat radiation area, radiating rate is faster relatively, and radiating effect is better.

The above is only a kind of preferred implementation of the present utility model.For the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, for example main body can also for metal master copper, silver or that alloy material is made, all belong to protection range of the present utility model.
