Abstract

The utility model provides a heat pipe radiator which comprises a plane heat pipe and a round tube-typed heat pipe, and is characterized in that the plane heat pipe and the round tube-typed heat pipe are connected and form a communicated and liaisoned body intracavity with liquid working fluid. The plane heat pipe of the utility model functions as a condensation segment of the gravity heat pipe; the round tube-typed heat pipe functions as an evaporation segment and an insulation transmission segment. Thus, the utility model has super high heat conduction performance of ordinary round tube-typed heat pipes and especially large heat radiation area of plane heat pipes, which brings new ideas for the box design of computers and pluralities of electronic power equipment. In addition, the round tube-typed heat pipe is made of flexible materials, and can be bended into shape at any moment and reach any position of heated bodies; therefore, the special structure is provided with great flexibility of installation and can solve the problem of heat radiation of heating components in computers and pluralities of electronic power equipment. The utility model has the advantages of free of resource and noise and realization of sealing boxes without exposing to dust, etc.

Description

A kind of heat-pipe radiator

(1) technical field

The utility model relates to a kind of heat-pipe radiator.

(2) background technology

Existing radiator for example, is used for the heat radiation of computer, and the main mode that adopts has blower fan heat radiation, liquid circulation heat radiation and heat pipe heat radiation, and it cuts both ways.Wherein, the blower fan heat radiation requires computer cabinet to seal, and blower fan itself has certain noise again, and therefore, dust and noise are its shortcomings; The danger of liquid circulation heat radiation is from contingent leak of liquid.And heat pipe heat radiation, its a kind of structure is common tubular heat pipe 1 as shown in Figure 1 and Figure 2, sealed at both ends, inside pipe wall face is zigzag composite surface 11 or reticulate pattern face, and vacuum shape in the pipe, fills small amount of liquid working medium; Its another kind of structure is a flat-plate heat pipe 2, and its form has two kinds: as shown in Figure 3 a kind of, and welding (or bonding) one or many general heat pipes on one flat plate; As shown in Figure 4 a kind of, include the compound slab of hollow pipeline, the working medium motion for liquid of its hollow tube road.Above-mentioned each heat-pipe radiator, to being used for the heat radiation of computer, because of its structure dullness, applicability is relatively poor, can not be installed in flexibly on the heated body, therefore usually is difficult to utilization.

(3) utility model content

The purpose of this utility model is to provide a kind of heat-pipe radiator, and the super-high heat-conductive performance of existing common tubular heat pipe has the especially big area of dissipation of flat-plate heat pipe again, and flexible for installation.

A kind of heat-pipe radiator provided by the utility model comprises a flat-plate heat pipe and a tubular heat pipe, it is characterized in that flat-plate heat pipe is connected with the tubular heat pipe, forms an intracoelomic cavity that contains liquid working substance and communications and liaison.

Above-mentioned heat-pipe radiator, wherein, the tubular heat pipe is to be made by flexible material.

Above-mentioned heat-pipe radiator, wherein, the pipeline of flat-plate heat pipe can be the single face projection, also can be two-sided projection.

Above-mentioned heat-pipe radiator, wherein, the shape of the projection pipeline of flat-plate heat pipe is a straight tube-like, or the honeycomb tubulose, or helix.

Owing to adopted above-mentioned technology solution, flat-plate heat pipe and a tubular heat pipe of a hollow coupled together, both inner chambers fuse, and become a kind of combined type heat pipe radiator of internal volume expansion.Its flat-plate heat pipe is as the condensation segment of gravity assisted heat pipe, the tubular heat pipe is as the evaporation section and the adiabatic span line of gravity assisted heat pipe, like this, the super-high heat-conductive performance of the existing common tubular heat pipe of the utility model, the especially big area of dissipation that flat-plate heat pipe is arranged again is for the design of the cabinet of computer and various all kinds of electron electric power equipment provides new approaches.In addition, the tubular heat pipe is to be made by flexible material, the brake forming of can whipping, arrive the heated body on the optional position, therefore, its particular structure has maximum Installation Flexibility, can solve the heat dissipation problem of heating components and parts in computer and the various all kinds of electron electric power equipment.The utility model does not need the energy, noiseless and can realize cabinet sealing and dustless or the like advantage.

(5) embodiment

As shown in Figure 5, the utility model is the heat-pipe radiator of combined type, by flat-plate heat pipe 1, after tubular heat pipe 2 connects, forms inner chamber and fuses, and vacuumizes the back in the chamber and annotates with liquid working substance.

Flat-plate heat pipe 1 is a kind of composite board with hollow pipeline, can realize with the method for inflation after the rolling seam, also can realize that material can be metals such as aluminium or copper, also can be plastics with the method for welding or the like other after the punch forming.

The inwall of tubular heat pipe 2 has shallow thin zigzag composite surface or structures such as reticulate pattern, screw thread; Material can be a metal, also can be plastics.

Liquid working substance can be liquid chemical industry, natural that water, acetone, various cold-producing mediums etc. easily undergo phase transition.

Flat-plate heat pipe 2 is the composite plates that the hollow pipeline is arranged, and has high specific stiffness, so it directly can be used as the outer surface of cabinet.As Fig. 6, shown in Figure 7, the pipeline projection of flat-plate heat pipe can be a single face, also can be two-sided.The flat-plate heat pipe of single face pipeline projection, it is pure flat that one side is arranged, and after suitable surface treatment, can become very smooth, beautiful cabinet outer surface.As the flat-plate heat pipe 2 of Fig. 8, Fig. 9 and pipeline projection shown in Figure 10, its pipeline figure is respectively straight tube road, honeycomb pipeline, spiral pipeline, has liquid and gathers performance as long as satisfy pipeline.As the cabinet outer surface, have extremely strong ornamental with this.The board edge of flat-plate heat pipe allows to do small size sheet metal works such as flanging; Whole plate allows to do 90.With interior bending, become various shaped as frames.These advantages make and the utlity model has extremely strong adaptability.

The heat-pipe radiator of combined type can be independent parts that are used for the casing assembling, also can be a body of box parts.

The course of work of the present utility model is: the tubular heat pipe 2 as evaporation section and adiabatic span line is to be made by flexible material, and the brake forming of can whipping arrives the heated body 3 on the optional position shown in Figure 5.This heated body 3 and institute must heat radiation machine internal heat generation element fit, by tubular heat pipe 2 with heat to flat-plate heat pipe 1 conveying, be dispersed in the machine external environment and go.This heat-pipe radiator provides the great degree of freedom for the design of machine inner structure, as long as guarantee that used tubular heat pipe position height is higher than heater element.
