Abstract

The utility model relates to a having middle heat transfer medium's indirect heating equipment in the closed conduct, specifically being an ultra -thin flat plate heat pipe, this ultra -thin flat plate heat pipe includes that flat -plate -shaped tube of a both ends confined and the cross section of laminating on its one side inner wall are wedge -form imbibition core, a serial communication port, the imbibition core be two to on the inner wall of reverse laminating both sides about flat -plate -shaped tube, form the steam flow path that a cross section is parallelogram between two imbibition cores, the densely covered slot that has the cross section to be the rectangle on the inner wall of the upper and lower both sides of flat -plate -shaped tube, this slot are the supplementary return flow line of condensate, and its direction is unanimous with steam flow path. It is more smooth and easy that ultra -thin flat plate heat pipe has the condensate backward flow, more safe and reliable's advantage.

Description

A kind of ultra-thin panel heat pipe
Technical field
The utility model relates to a kind of heat-exchange apparatus having intermediate heat medium in closed conduct.
Background technology
Heat pipe is a kind of novel heat transfer element invented by George Ge Luofo (GeorgeGrover) of U.S. Los Alamos (LosAlamos) National Laboratory in 1963, it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and phase change medium, be delivered to rapidly outside thermal source by the heat of thermal objects through heat pipe, its capacity of heat transmission exceedes the capacity of heat transmission of any known metal.Since appearance, heat pipe is with its high pyroconductivity, and excellent average temperature performance, the feature such as opposite sex making can be widely used in the fields such as Aero-Space, oil, food, chemical industry, air conditioner refrigerating.
Along with the kind of the development heat pipe of science and technology is more and more abundanter.At present, distinguish by version general heat pipe, separate heat pipe, hair can be divided into thread pump loop heat pipe, micro heat pipe, flat-plate heat pipe, radial heat pipe etc.; Wherein, flat-plate heat pipe is widely used because it has larger thermal diffusion area.The application for a patent for invention being CN104567497A as application publication number discloses a kind of heat pipe with ultrathin capillary structure, this heat pipe is made up of the liquid-sucking core be attached on a plane tube wall in a tabular shell and shell, and the cross section of described liquid-sucking core is the wedge shape from tabular shell one side to another side convergent.This structural design can make liquid-sucking core obtain larger capillary surface sum fluid transport sectional area.But the liquid-sucking core that only a plane tube wall has been sticked in this application middle plateform shape shell, another plane tube wall does not then have.When steam condensation on another plane tube wall described can be adsorbed thereon after forming fine drop, the heat absorption position of heat pipe cannot be back in time, be unfavorable for the circulation of heat transfer medium.In addition, another described plane tube wall is not sticked liquid-sucking core, and its part near thermal source, owing to can not get the cooling of liquid heat transfer medium, is easy to Yin Wendu too high and burn.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of ultra-thin panel heat pipe, and this ultra-thin panel heat pipe has the more smooth and easy and more safe and reliable advantage of condensate liquid backflow.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of ultra-thin panel heat pipe, the tabular shell that this ultra-thin panel heat pipe comprises a closed at both ends is the liquid-sucking core of wedge shape with the cross section be fitted on its side inwall; It is characterized in that,
Described liquid-sucking core is two panels, and is oppositely fitted on the inwall of the upper and lower both sides of tabular shell, forms the steam channel that a cross section is parallelogram between two liquid-sucking cores; The inwall of the both sides up and down of described tabular shell is densely covered with the groove that cross section is rectangle, and this groove is the auxiliary reflux passage of condensate liquid, and its direction is consistent with steam channel.
The utility model has following beneficial effect compared to prior art:
Because the inwall up and down of tabular shell directly contacts with two liquid-sucking cores respectively, and on the upper and lower inwall of tabular shell, offer the auxiliary reflux passage of groove as condensate liquid of rectangle, therefore there will not be tube wall to can not get cooling and the situation of burning.
Accompanying drawing explanation
Fig. 1 ~ 3 are the structural representation of the utility model specific embodiment; Wherein, Fig. 1 is front view, and Fig. 2 is the A-A sectional view in Fig. 1, and Fig. 3 is the enlarged drawing of local I in Fig. 2.
Fig. 4 is the perspective view of Fig. 1 ~ 3 illustrated embodiment.
Detailed description of the invention
See Fig. 1 ~ 4, the ultra-thin panel heat pipe in this example comprises the tabular shell 1 of closed at both ends and the two panels liquid-sucking core 2 of Qi Nei.
See Fig. 2 and 3, the cross section of described two panels liquid-sucking core 2 is wedge shape, and is oppositely fitted on the inwall of tabular shell about 1 both sides.Space between described two liquid-sucking cores 2 forms the steam channel 3 that a cross section is parallelogram.The inwall of the both sides up and down of described tabular shell 1 is densely covered with the groove 1-1 that cross section is rectangle, this groove 1-1 is the auxiliary reflux passage of condensate liquid, and its direction is consistent with steam channel 3.
See the liquid-sucking core 2 described in Fig. 2 and Fig. 3, there is capillary structure, and formed by metal powder sintered.
See Fig. 1, be vacuum state in described ultra-thin panel heat pipe, and be marked with the conventional heat transfer medium of heat pipe, it all can be used as evaporator section and absorbs heat to being attached on thermal source in any one end up and down, and the corresponding other end is then as condensation segment release heat.
