Abstract
The utility model relates to an assistant capillary structure for a heat pipe. An internal wall surface of a lengthwise pipe is provided with a groove, and the interior of the pipe is provided with the assistant capillary structure and is divided into a vaporization part, an insulation part and a condensation part, wherein the vaporization part and the insulation part on the internal wall surface of the pipe are provided with capillary structures which are provided with smaller effective capillary apertures compared with the condensation part; and the assistant capillary structure axially arranged inside the pipe is an open air flow passage formed by the vaporization part extending to the condensation part. With the application of the assistant capillary structure, the heat conducting efficiency in the pipe is strengthened so as to increase the heat transfer rate.
Description
Technical field
The utility model relates to a kind of heat pipe auxiliary capillary structure that heat conduction path is provided between the hydraulic fluid in effective thermal source to external world and the pipe that can be used as.
Background technology
The application that has heat pipe now mainly is to be to utilize the heat that absorbs the latent heat carburation by evaporation of heating electronic building brick generation at the inner working fluid of filling of body in its evaporation part, this heat also discharges heat in condensation part liquefaction condensation, condensed working fluid continues shuttling movement under the capillarity in body, distributes with the heat conduction that electronic building brick is produced.
For the capillary structure of avoiding body inside can not with the time make the condensation part working fluid be back to evaporation part circulation heat radiation, make heat pipe forfeiture heat transmission function, more serious meeting makes the assembly Yin Gaowen of heating and burns.
Summary of the invention
In view of this, be defective in the application that improves existing heat pipe, main purpose of the present utility model is, a kind of auxiliary capillary structure that axially is provided with in body is provided.
For achieving the above object, the technical solution adopted in the utility model is, a kind of auxiliary capillary structure that axially is provided with in body is provided, be provided with groove at a lengthwise inboard wall of tube body face, be provided with the auxiliary capillary structure in the body, the body inner area is divided into the evaporation part, insulation and condensation part, wherein, the evaporation part and the insulation of described inboard wall of tube body face are provided with capillary structure, the capillary structure of described evaporation part and insulation has littler capillary aperture than the condensation part, and the auxiliary capillary structure that axially is provided with in the body is to extend to the condensation part by the evaporation part to form an open gas flow passage.
The beneficial effects of the utility model are compared with the prior art, extend to the condensation part by the evaporation part and form an open gas flow passage, promote the capillary force of capillary structure, and effectively the working media in the body are effectively conducted, and promote radiating effect.

The specific embodiment
Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.
See also Fig. 1 to shown in Figure 3, the body 1 of heat pipe of the present utility model is made by copper material, body 1 inner area is divided into evaporation part A, insulation B and condensation part C, can be used as and conduct heat to body 1 inside, heat energy via materials such as water or other suitable fluid such as alcohol, methyl alcohol, acetone as working media, described working media is in evaporation part A heat absorption evaporation, and working media is delivered to that condensation part C is condensed into liquid and heat release reaches radiating effect.
Mainly be to be at a lengthwise body 1 internal face to be axially arranged with plural tiny groove 11, working media is flowed in body 1.The evaporation part A and the insulation B of described body 1 internal face are provided with capillary structure 2, and the set capillary structure 2 of evaporation part A and insulation B is formed by silk screen or copper powder institute sintering, and this capillary structure 2 partly has littler capillary aperture than condensation part 3.
Be positioned at the auxiliary capillary structure 3 that body 1 axially is provided with, it is to extend to condensation part C by evaporation part A through insulation B to form an open gas flow passage, described auxiliary capillary structure 3 is formed by the silk thread braiding, its silk thread material is a copper, auxiliary capillary structure 3 is a rectangle groove shape, it is to be combined in capillary structure 2 surfaces that the insulation B that described evaporation part A extends to condensation part C leading edge is provided with the set auxiliary capillary structure 3 in position, and other extends to the auxiliary capillary structure 3 of condensation part C and adopts the hanging shape setting.
See also Fig. 4 and shown in Figure 5 again, described body 1 after flatten being shaped has thermal conducting function equally, and the evaporation part A in the body 1 is provided with auxiliary capillary structure 3 between the C of condensation part, can promote the heat transfer property of body 1.
From the above and preferred embodiment shown in the drawings as can be known, being designed to of this case a kind ofly can promote heat conducting heat pipe auxiliary capillary structure, auxiliary capillary structure 3 by rectangular channel form is axially disposed within body inside, and it can promote the circulation and reinforcement radiating effect of working media.And true the research and development by this case utility model designer of the technological means of this case utilization and structure thereof forms, and this case utility model is really to meet the important document of novel patent, and the applicant files an application in accordance with the law.
More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
