The supporting body is a flake, on which a plurality of perforating grooves are arranged, the perforating grooves serve as the steam passage. The supporting body sticks on the inner wall surface of the pipe body by head-tail connecting, and the fibrous bundles are fixed between the inner wall of the pipe body and the supporting body, the gap is arranged among the fibrous bundles and between the fibrous bundles and the pipe wall to form porous structure, so the porous capillary organization increases the capillary force to the working flow, and thus the heat transfer efficiency of the heat pipe is improved.
Description
Technical field
The utility model relates to a kind of radiator structure, particularly a kind of heat pipe structure with capillary structure.
Background technology
Because present being seen electronic product, under technology constantly promotes, and the exploitation of cooperation new material, pure growth has been arranged in the integration of function, simultaneously, the structure of electronic product and outward appearance also meet user's needs and convenience gradually, will more lead as main towards compact design.Yet, when the electronic product pursuit is lightening, because under the influence of function diversification, various assemblies also increase day by day, the caloric value that is produced also promotes day by day relatively, therefore in order to make the electronic product can be in normal operating temperature running, to avoid the temperature rise environment and reduce service life of electronic product, the heat radiation countermeasure of appropriateness becomes one of key point of development.
Therefore the radiator structure that has heat pipe has become best heat radiation to select, because inside heat pipe is provided with capillary structure and the working fluid that is used for conducting heat, by causing working fluid to convert gas phase state to after the heat exchange action, after conducting to heat on the radiator fast, with the exchange heat that absorbed to the radiator that is connected, change back liquid phase state again, be back to the original place by the capillary structure effect more at last, to carry out circulating heat conduction.Because the structure of heat pipe has the advantage of lightness, quite is suitable as the heat radiation countermeasure that turns to the electronic product of main shaft with frivolous.
Because the heat transfer efficiency of heat pipe is to be based upon cooperatively interacting of capillary structure and working fluid, particularly at capillary structure, provide working fluid to produce capillarity, so that working fluid at inside heat pipe after condensing into liquid state after the release heat, by capillarity circulation again again, so the concern heat transfer efficiency of this heat pipe of the power of capillarity.
And in the past prior art with metal powder sintered at the tube body of heat pipe inwall, to form porous capillary structure structure, though yet the capillary structure that utilizes metal dust to constitute can provide the preferable capillary force of working fluid to accelerate the backflow of working fluid, but, weakened the heat conduction efficiency of heat pipe relatively because of the formed capillary structure structure of its metal dust also produces bigger thermal resistance effect.
Therefore prior art adopts woven mesh structure to be used as the capillary structure of inside heat pipe afterwards, to improve the shortcoming of the high thermal resistance of aforementioned metal powder, but the netted hole of mesh grid is bigger, and the capillary force that is produced still can't reach best heat-conducting effect but not as the structure that metal dust produced.And another kind of the utilization at inside heat pipe forms the capillary force that capillary structure is strengthened heat pipe with groove, but the capillary structure that forms with groove destroys the capillary force of its groove easily in the molding process of the bend pipe of heat pipe or flattening, particularly more obvious on long heat pipe.Therefore, how to improve the defective of aforementioned two kinds of structures simultaneously, can take into account both advantages again, become technical staff's desire problem place to be solved of being familiar with this technology.
The utility model content
At above-mentioned defective, main purpose of the present utility model is to provide a kind of capillary structure of composite construction, by a plurality of fibre bundles being located on the inboard wall of tube body with a plurality of grooves, by having the gap between each fibre bundle and between fibre bundle and tube wall to form cellular structure, and be fixed on this body inside with supporter, except convenient the making, also can promote the capillary force of this capillary structure, promote the heat transfer efficiency of this heat pipe.
To achieve the above object, the utility model provides a kind of capillary structure structure of heat pipe, be located at the inboard wall of tube body face position of heat pipe, this structure comprises a plurality of fibre bundles and supporter, wherein this inboard wall of tube body has a plurality of axial microscler grooves, this fibre bundle is evenly distributed on the inner wall surface of this body and groove inside to provide the axial length of body apart from capillary force, on supporter, be provided with a plurality of grooves of wearing, subsides are against this tube body of heat pipe internal face, fibre bundle is fixed between this inboard wall of tube body face and supporter, and make between each fibre bundle and fibre bundle and tube wall and fit tightly the formation cellular structure, promote capillary force thus, to promote the heat transfer efficiency of this heat pipe to working fluid.
