Abstract

The utility model discloses a heat pipe structure. The internal wall of a pipe is provided with a plurality of grooves and capillary structures, so that the groove and capillary structure is utilized to make the capillary effect larger than the gravity; therefore, the utility model can not only be used in any angle and matched with materials of various shapes, but also enhance the heat transfer efficiency and heat-conducting benefit so as to achieve the maximum heat transfer effect.

Description

Heat pipe structure

Technical field

The utility model refers in particular to a kind of have simultaneously groove and capillary structure relevant for a kind of heat pipe structure, makes capillarity greater than centrifugal force, and can be used in any angle of inclination, and increase the heat pipe structure of maximum heat biography amount.

Background technology

Continuous lifting along with the 3C industry, make electronic component move towards compact trend, various host computer of while, the computer relevant device is when using, for inside chip such as central processing unit or drawing chip are operated with higher work clock pulse, often must increase the number of transistors in the chip, and along with the increase of number of transistors, also can allow power consumption, power increases, the related chip that causes can produce higher heat in use, this moment is not good as the radiating efficiency of fruit chip, to cause chip to produce fault or the generation of the situation of computer crash easily, also therefore, the radiating efficiency of chip is an epochmaking problem, generally can be provided with heat pipe to reduce temperature, because heat pipe is the composite set that hollow tube includes capillary structure and hydraulic fluid in chip, when heat acts on the heat pipe, hydraulic fluid is evaporated to steam and flows to the other end, works as devaporation, become hydraulic fluid again and after heat shed, hydraulic fluid was refluxed by capillary structure again.

Above-mentioned heat pipe has a body, forms the compound capillary structure of one deck on the inner peripheral surface of body, and capillary structure is constituted by having capillary mesh grid, has preferable pliability, changes shape with the body that cooperates any bending.

Yet above-mentioned heat pipe has following disappearance in the use:

1. above-mentioned heat pipe must form the compound capillary structure of one deck in addition on the inner peripheral surface of body, just can have capillarity and reach heat sinking function, results in the rising of manufacturing cost.

2. above-mentioned heat pipe is in the technical process with the body bending, and the capillary structure that mesh grid constituted breaks away from the inner peripheral surface of body easily, causes the reduction of radiating efficiency.

So have the dealer to create the heat pipe of another kind of pattern, this heat pipe has a body, tool plural number groove in the body, groove extends axially to produce capillarity along this body.

Yet above-mentioned heat pipe is when condensation end is lower than heating end, and capillarity will make hydraulic fluid to carry and be back to heating end less than the effect of gravity, results in the inefficacy of heat sinking function.

If the inventor uses the capillary structure that mesh grid constituted in view of above-mentioned heat pipe, because breaking away from the inner peripheral surface of body when the bending body, capillary structure reduces radiating efficiency easily, if use groove then can when condensation end is lower than heating end, lose heat sinking function, so in line with asking progressive spirit and theory, and under the assisting a ruler in governing a country by the professional knowledge of being accumulated for many years, technology, experience, constantly be devoted to improve and exploitation, thereby create the utility model.

Summary of the invention

The purpose of this utility model is to provide a kind of heat pipe structure, and this structure has groove and capillary structure simultaneously, makes capillarity greater than centrifugal force, can be used in any angle of inclination, and increases maximum heat biography amount.

Heat pipe structure of the present utility model, it has a body, and the inwall of body is formed with most grooves along extending axially of body, and is provided with capillary structure in the whole inwall of body, and capillary structure is the reticulate body that is formed by most metal wire knitted.

From the above mentioned, heat pipe structure of the present utility model utilizes groove and capillary structure to make capillarity greater than centrifugal force, and can be used in any angle of inclination, cooperating various difform materials, and can increase hot transfer efficiency and quick conductive benefit, reach the effect that increases maximum heat biography amount.

The specific embodiment

At first, please refer to Fig. 1～shown in Figure 3, is the schematic diagram of the utility model heat pipe structure one preferred embodiment, and it is combined by a body 1 and a capillary structure 2, wherein:

This body 1 is the copper pipe in order to the splendid attire hydraulic fluid, the purpose of dispelling the heat to reach transfer heat, and the inwall of body 1 is formed with a plurality of grooves 11 along extending axially of body 1;

This capillary structure 2 is woven the reticulate body that forms by most wire.

When implementing assembling, see also Fig. 4 and Fig. 5, it is that capillary structure 2 is smooth in the whole inwall of body 1, utilize the capillarity of groove 11, the capillarity that cooperates capillary structure 2 again is greater than centrifugal force, make body 1 not necessarily will be horizontally disposed with and can be used in any angle of inclination, and hydraulic fluid guides to heating end to absorb heat by groove 11 and capillary structure 2 when using, make the hydraulic fluid of body 1 heating end be evaporated to steam, steam flows to the other end of body 1 by body 1, work as devaporation, become hydraulic fluid again and after heat shed, hydraulic fluid is flowed back to the heating end of body 1 again by the groove 11 of body 1 inwall and capillary structure 2, so promptly finish a thermal cycle, and repeat function and take away a large amount of heat energy and be dissipated in the air.

Referring again to Fig. 6 and shown in Figure 7, be the utility model heat pipe structure its two with and the schematic diagram of three preferred embodiments, be in this body 3,4 with the difference of one preferred embodiment and bend to L shaped and U-shaped respectively, and it is capillary structure 2 is smooth in the whole inwall of body 3,4, and any other the shape of body 3,4 also flexible one-tenth, even can be pressed into plane and with the material on plane preferable combining arranged, to reach preferable radiating effect.

Though the utility model discloses with specific embodiment; but it is not in order to limit the utility model; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.

By above-mentioned element form with implementation as can be known, the utility model and existing structure the utlity model has following advantage in comparison:

1. the utlity model has the capillarity and the low-cost advantage of groove, the capillarity that cooperates capillary structure is greater than centrifugal force, and in non-horizontally disposed occasion, can be in the start of any angle of inclination, condensate liquid guides to capillary structure by groove, can provide the rapid supply of hydraulic fluid to return heating end, increases hot transfer efficiency and quick conductive benefit, and can increase maximum heat biography amount, at same caliber size outstanding performance can be arranged.

2. any shape of the flexible one-tenth of the utility model, even can be pressed into plane and preferable combining arranged with the material on plane, to cooperate various difform materials, for example electronic product (computer, PDA, GPS), household supplies (roasting plate, deep fryer, bathtub, water heater, furnace), heat exchanger (heat exchanger of control panel, electric box, boiler), all kinds of machinery (semiconductor, electronic loop, sound equipment power crystal cooler) and all kinds of facility (non-individual bodies such as mould, iron material add thermal roller) are promoted the value of using in fact more.
