Abstract

The utility model discloses a heat conduction device. The device comprises a graphite substrate, a double-sided adhesive, and a heat conducting copper tube. The graphite substrate is in a sheet-shape structure; the heat conducting copper tube is in a flat structure; and two faces of the double-sided adhesive are pasted onto the graphite substrate and the heat conducting copper tube respectively. By arranging the heat conducting copper tube to be a flat structure, the device breaks the restriction in the conventional art that copper tubes are in circular structure, so that the device can be used in a wider range, and applies to thinner products better. By pasting the sheet-shape graphite substrate and the flat heat conducting copper tube via the double-sided adhesive to form one piece, combination of the graphite substrate and the heat conducting copper tube enhances the heat conducting and sinking performances, so that heat is reduced more and quicker. The temperature differences between two ends and between two sides are also effectively decreased, so that the temperatures are more even at the two ends and the two sides, product components are protected from damage, and much convenience is brought to enterprises and users.

Description

A kind of heat-transfer device

Technical field

The utility model relates to heat conduction and heat radiation material application, particularly a kind of heat-transfer device for heat conduction and heat radiation.

Background technology

In recent years, development along with electronic technology, especially the continuous renewal of smart mobile phone, notebook computer, panel computer and large-scale server is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, its caloric value is also increasing, and the heat conduction and heat radiation that therefore rationally effectively solves the said goods is the difficult problem in industry always.

In traditional handicraft, usually adopt heat-conducting copper pipe to realize heat conduction and heat radiation, utilize the liquid state of the cooling fluid in copper pipe and the mutual conversion of gaseous state, heat is effectively shed, although heat-conducting copper pipe has good uniform temperature, size during its application is generally all larger, often is used in larger equipment, shape mostly is circular configuration, uses and has certain limitation.In modern crafts, usually adopt graphite heat radiation fin as the preferred material that solves heat conduction and heat radiation, graphite heat radiation fin can be along level, vertical direction heat conduction, its size is changeable, and it laminar structuredly can make it be applicable to the surface of any product better, although the speed ratio of graphite heat radiation fin heat conduction and heat radiation is very fast, but its uniform temperature is not very good, usually have the apparent in view temperature difference at its two ends and both sides, too high easy some element to product of the temperature difference causes damage, may cause scrapping of element when serious, bring unnecessary economic loss and trouble to enterprise or user.

The utility model content

For solving the problem existed in the above-mentioned background technology, the purpose of this utility model is to provide a kind of heat-transfer device, to reach, not only strengthens its heat conduction and heat radiation performance, also effectively reduces the purpose of the temperature difference.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of heat-transfer device, comprise graphite matrix, double faced adhesive tape and heat-conducting copper pipe, and described graphite matrix is laminated structure, and described heat-conducting copper pipe is flat-shaped structure, and the one side of described double faced adhesive tape is pasted mutually with described graphite matrix, and another side is pasted mutually with described heat-conducting copper pipe.

Preferably, described graphite matrix is artificial graphite flake.

By technique scheme, the heat-transfer device that the utility model provides, heat-conducting copper pipe is set to flat-shaped structure, has broken the restriction of circular configuration in the traditional handicraft, makes its scope of application wider, is more suitable for using in the product that compares book; By double faced adhesive tape, the graphite matrix of sheet and flat-shaped heat-conducting copper pipe pasted and be shaped to one, the two combination has not only been strengthened to its heat conduction and heat radiation performance, heat is fallen lower, fall faster, also effectively reduced the temperature difference of two ends and both sides, make the more uniform temperature of two ends and both sides, the element that has guaranteed product is injury-free, has brought very large convenience to enterprise or user.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.

The perspective view that Fig. 1 is a kind of heat-transfer device of the utility model embodiment.

In figure, number designation means the title of parts:

1, electrographite sheet 2, double faced adhesive tape 3, heat-conducting copper pipe

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

A kind of heat-transfer device that the utility model provides, as shown in Figure 1, comprise electrographite sheet 1, double faced adhesive tape 2 and heat-conducting copper pipe 3, electrographite sheet 1 is laminated structure, heat-conducting copper pipe 3 is flat-shaped structure, and the one side of double faced adhesive tape 2 is pasted mutually with electrographite sheet 1, and another side is pasted mutually with heat-conducting copper pipe 3.

In use procedure, the another side of the another side of electrographite sheet 1 or heat-conducting copper pipe 3 and the element of product can be affixed, electrographite sheet 1 is more smooth because of it, therefore itself and the better effects if that contacts of element, if as required, heat-conducting copper pipe 3 also can adopt the mode of welding to contact with element, and effect is remarkable equally.

The disclosed a kind of heat-transfer device of the utility model, heat-conducting copper pipe is set to flat-shaped structure, has broken the restriction of circular configuration in the traditional handicraft, makes its scope of application wider, is more suitable for using in the product that compares book; By double faced adhesive tape, the graphite matrix of sheet and flat-shaped heat-conducting copper pipe pasted and be shaped to one, the two combination has not only been strengthened to its heat conduction and heat radiation performance, heat is fallen lower, fall faster, also effectively reduced the temperature difference of two ends and both sides, make the more uniform temperature of two ends and both sides, the element that has guaranteed product is injury-free, has brought very large convenience to enterprise or user; Simultaneously, this heat-transfer device is not only simple in structure, and result of use is remarkable.

To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
