Description

The heat pipe structure improvement

Technical field

A kind of heat pipe structure improvement refers to a kind of heat pipe structure improvement that can strengthen the support force of plate heat pipe and can promote the heat pipe fine ratio of product especially.

Background technology

Along with industry constantly develops, removing of cooling or heat is a big obstacle of electronic industry development all the time.Along with the raising and the multi-functional application of dynamical requirement, degree of integration, also face big challenge for the requirement of dispelling the heat, so just become the major subjects of electronics industry for the research and development of heat transfer efficient.

Fin (Heat Sink) is used in heat dissipation that electronic component or system are produced usually among atmosphere; And under the lower situation of thermal resistance, show that described fin has higher radiating efficiency.In general, thermal resistance is made of the diffusion thermal resistance of fin inside and the thermal-convection resistance between described fin surface and the atmospheric environment; On using, the material of high conductance such as copper, aluminium etc. often are used to make fin to reduce the diffusion thermal resistance; Yet thermal-convection resistance has limited the usefulness of fin, makes it can't reach the heat radiation requirement of electronic component of new generation.

Therefore, existing market all is conceived to more efficient cooling mechanism, and propose to have the slim heat pipe (Heat pipe) and the soaking plate (Vapor chamber) of high heat conduction efficiency successively, and itself and radiator are made matched combined, with effective solution heat dissipation problem of present stage.

Present slim heat pipe structure, be that the hollow space that sees through in slim heat pipe is inserted metal dust, and the mode that sees through sintering forms the capillary structure of a sintered form at the inwall of described temperature-uniforming plate, or insert its hollow space as capillary structure with wire netting, thereafter described slim heat pipe is vacuumized and fill working fluid and seal at last; Because slim heat pipe of the prior art is spoilt because of the design of unbraced structure can cause and is fallen into or thermal expansion, therefore when described slim heat pipe is pressurizeed, the capillary structure of described slim inside heat pipe (being the metal dust of sintering) is vulnerable to squeeze and destroy and comes off from the inwall of described slim heat pipe, therefore make the heat biography usefulness of described slim heat pipe significantly reduce, and because of described slim heat pipe only has capillary structure or hollow part to have wire netting at described chamber inner wall mask, therefore when hydraulic fluid is liquid state by vaporization and condensation, only can lean on the capillary structure of gravity or wall to reflux, its vapour-liquid cycle efficieny is very not good.

Taiwan novel patent patent No. M336673, be to disclose a kind of temperature-uniforming plate and supporting construction thereof, described temperature-uniforming plate comprises housing and is installed with capillary structure and supporting construction in its enclosure interior, this supporting construction comprises a plate body, on plate body, offer the plural conduit of corresponding arrangement and arranged spaced, form a wave sheet respectively in each conduit inside, the both ends of the surface up and down of described wave sheet press on capillary structure respectively, and the internal face of capillary structure and housing is amplexiformed mutually; See through the hollow part that described wave sheet is arranged on temperature-uniforming plate, though described wave sheet can solve aforementioned sintered powder and be oppressed and hang or spoil sunken phenomenon and increase the vapour phase variable quantity, increase the transmission speed of heat, the wave sheet there is no the effect that the liquid working fluid of remarkable help refluxed, increased the capillary limit.

In existent technique, no matter be its inner supporting structure of temperature-uniforming plate or slim heat pipe present stage target still for actively improving; Therefore prior art has following shortcoming:

1. it is not good to produce yield;

2. the vapour-liquid cycle efficieny is not good;

3. supporting construction is bad.

The utility model content

Therefore, for solving the shortcoming of above-mentioned prior art, main purpose of the present utility model, providing a kind of plural grid of thin slice body that utilizes increases the transmission speed of vapour phase variable quantity, heat, and utilizes the preferable support force of projection increase and can utilize the projection with capillary structure to increase the speed of liquid working fluid backflow to improve the capillary limit.

Provide the improvement of a kind of heat pipe structure for reaching above-mentioned purpose the utility model, comprise: body, thin slice body, at least one projection;

Described body has an accommodation space, and described accommodation space two ends connect one first blind end and one second blind end respectively, have working fluid in the described accommodation space; Described thin slice body is located in the accommodation space of light-emitting diode body, and described thin slice body has plural first extension and plural second extension, the interlaced connection of described first and second extension, and define plural grid jointly; Described projection is located at the arbitrary interlaced place of described first and second extension, and described projection two ends are to connect described thin slice body and described body respectively.

Therefore above-mentioned heat pipe structure is the supporting degree and the hot transfer efficiency that can significantly promote heat pipe structure.Further understand feature of the present utility model and technology contents for making, see also following about detailed description of the present utility model and accompanying drawing.
