Abstract
The invention relates to a heat pipe which comprises a sealed shell, a work medium filled in the shell and a capillary structure covered on the inner wall of the shell. The shell is made of an aluminum product plated with a copper layer, so that not only is lighter weight of the heat pipe ensured and is the cost saved, but also the heat pipe approximately completely made of the copper material has heat-conducting property.
Description
Technical field
The present invention relates to a kind of heat pipe, particularly relate to a kind of heat pipe of light weight.
Background technology
At present, because heat pipe has heat transfer rate faster, and be widely used in the heat radiation of the electronic component of the big caloric value of tool.Existing heat pipe adopts the copper with high thermal conductivity as housing usually; But appearance along with multi-functional and ultrathin electronic product; The performance of opposite heat tube and light-weighted requirement also improve all the more, adopt aluminium with high thermal conductivity and lighter weight to become the target that people pursue as the housing of heat pipe.Yet, because aluminium is easy to generate alumina layer, be not easy to weld, and contact angle, the density property of the working medias such as water in aluminium and the heat pipe are relatively poor, thereby influence the heat conductivility of heat pipe with other workpiece.
Summary of the invention
In view of this, the heat pipe that is necessary that a kind of lighter weight is provided and has better heat-conducting effect.
A kind of heat pipe, comprise a sealing housing, be filled in the working media in this housing and be covered in the capillary structure on the inner walls, this housing is coated with the manufacturing of copper layer by the outside of aluminium and forms.
A kind of heat pipe, comprise a sealing housing, be filled in the working media in this housing and be covered in the capillary structure on the inner walls, this housing is coated with the manufacturing of copper layer by the outside of aluminium and forms, this working media is a water.
Compared with prior art, the mode that the housing of this heat pipe adopts the outside of aluminium to be coated with the copper layer is made, and both can guarantee that heat pipe has lighter quality, practices thrift cost, can make it have the heat conductivility that is close to fully the heat pipe of being made by copper material again.Simultaneously, again can so that with other workpiece, like the welding of radiating fin group, copper coin etc., avoid the relatively poor problem of contact angle, density property of the working medias such as water in aluminium and the heat pipe, and then guarantee that heat pipe has high heat-conducting property.

The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
Fig. 1 is the stereogram of an embodiment of heat pipe of the present invention, is example with straight type tubular heat tube in the present embodiment.Please consult Fig. 2 simultaneously, this heat pipe 100 comprises that the housing 10 of a tubulose, the working media 20 and that is filled in the housing 10 are covered in the capillary structure 30 on housing 10 inwalls.
The cross section of this housing 10 is circular, and the copper-plated material of its outer surface by aluminium is processed.This housing 10 comprises the aluminium 11 of a tubulose and is located at the inner surface of this aluminium 11 and the copper layer 12 of outer surface.These housing 10 its interior seal chambers 15 that form, sealing cavity 15 generally is pumped into vacuum or near vacuum, is beneficial to the thermal evaporation that receives of working media 20.Simultaneously, sealing cavity 15 also is the steam channel that becomes steam after being heated as hydraulic fluid.Working media 20 is generally the higher liquid of latent heat such as water, alcohol, ammoniacal liquor and composition thereof.This capillary structure 30 can be capillary structures such as silk screen, groove, carbon nano pipe array.
Because the mode that the housing 10 of this heat pipe 100 adopts the outside of aluminium 11 to be coated with copper layer 12 is made; Compared to existing complete heat pipe by flexible; Both can guarantee that heat pipe 100 had lighter quality; Practice thrift cost, can make it have the heat conductivility that is close to fully the heat pipe of making by copper material again.Simultaneously, again can so that with other workpiece, like the welding of radiating fin group, copper coin etc.Avoid the relatively poor problem of contact angle, density property of the working medias such as water in aluminium and the heat pipe, guarantee that heat pipe has high heat-conducting property.
It is understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
