Abstract
The utility model discloses a heat pipe for heat transfer. The heat pipe comprises a heat pipe evaporation segment, wherein a cylindrical vapor heat dissipation segment formed by a sintering filter element with multilayer metal meshes is further arranged in the middle of the heat pipe evaporation segment; and the external diameter of the vapor heat dissipation segment is in close fit with the interior of the heat pipe. By adopting the above scheme, when the heat pipe is in operation, heat on the inner wall of the heat pipe is quickly transferred to all parts of the sintering filter element, and as liquid is infiltrated in the whole porous sintering filter element, evaporation can be performed in an area dozens of times larger than the original area, the evaporation heat resistance of the evaporation segment is greatly reduced, and the integral efficiency of the heat pipe is improved.
Description
Technical field
The present invention relates to heat pipe, especially use the heat pipe of sintered filter core as evaporator section.
Background technology
Heat pipe is the fabulous parts of a kind of heat transfer property; The principle that relies on its phase transition of vacuum to conduct heat; Have that thermal resistance is low, the characteristics of reliable operation, be called as " superconductor " of heat transfer, thereby be widely used in fields such as power electronics, coal, oil, track traffic, metallurgy.
Heat pipe is in work, and heat passes to evaporator section by the outside, and then passes to medium; Make medium be heated and flash to gas, be diffused into whole heat pipe inner chamber, meet condensation when gas at condensation segment and form liquid by liquid; Rely on gravity to flow back to evaporator section, discharge heat simultaneously.Therefore, in order to improve the Heat Transfer of Heat Pipe on Heat Pipe performance, reduce and transmit thermal resistance, the most directly way increases the surface area of evaporator section and condensation segment.
For present heat pipe, increasing the main means of evaporator section surface area has copper powder sintering, use fluted tube, built-in copper mesh etc.For the heat pipe of diameter less than 10 millimeters, owing to mainly partly adopt press-fit approach with the heat absorption heat release, thereby generally adopt the way of copper powder sintering; Diameter is greater than 10 millimeters heat pipe, because partly adopt the technology of nest plate with heat release, if sintering can cause copper pipe annealing, and undercapacity, therefore general fluted tube and the built-in copper mesh way of adopting.But fluted tube is owing to the relation of wall thickness, and conduit can not be too dark, so the area increase is limited, generally in 15%.The way of built-in copper mesh, because copper mesh is inner at copper pipe, the applying between it is mutual is not sure of, so its performance still remains to be investigated.
The utility model content
The object of the invention be exactly to present diameter at the heat pipe more than 10 millimeters, through using a kind of movable sintered filter core, be fixed on the evaporator section of heat pipe with the mode of assembling, in order to increase the contact area of evaporator section and medium.
It is following that the utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of heat pipe of the usefulness of conducting heat; Comprise heat pipe evaporator section; Wherein, the centre of said heat pipe evaporator section also is provided with the steam radiating segment that is formed by the sintered filter core that the multiple layer metal net is arranged; Said steam radiating segment is processed cylindric, and its external diameter and inside heat pipe closely cooperate.
Further preferred construction is, said steam radiating segment is provided with a plurality of in order to the hole as steam passages, and these holes are made up of the mesh that sintered filter core itself has.
Further preferred construction is that the diameter of said heat pipe evaporator section is more than 10 millimeters.
The utility model has been taked after the such scheme; In work, the heat transferred sintered filter core of heat pipe inwall makes heat be delivered to each position of sintered filter core very soon; And liquid has all been soaked in cavernous sintered filter core inside; Therefore can evaporate on tens times the area obtaining than increasing in the past, therefore greatly reduced the evaporation thermal resistance of evaporator section, improved the overall efficiency of heat pipe.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the sketch map of the heat pipe of the utility model heat transfer usefulness.
The specific embodiment
Come the utility model is described below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the sketch map of the heat pipe of the utility model heat transfer usefulness.Wherein, as shown in the figure, shown in the heat pipe of heat transfer usefulness, comprise heat pipe evaporator section 1, wherein, the centre of said heat pipe evaporator section 1 also is provided with the steam radiating segment 2 that is formed by sintered filter core, said steam radiating segment is processed cylindric, its external diameter and inside heat pipe closely cooperate.
And said steam radiating segment is provided with a plurality of in order to the hole 3 as steam passages.
Wherein, Sintered filter core is a kind of by the multiple layer metal sintering net, adopts the multilayer stainless (steel) wire through special lamination compacting, a kind of novel filter material with higher-strength and whole rigidity that forms through vacuum-sintering; The mesh of its each layer silk screen is interlaced; Form a kind of homogeneous and desirable structure, wherein, these mesh are used to form described hole 3.
And, shown in sintered filter core have good hear resistance: can be durable in from the continuous filtration of 650 degree at the most of-200 degree.
Wherein, the utility model has been taked after the such scheme, in work; The heat transferred sintered filter core of heat pipe inwall; Therefore make heat be delivered to each position of sintered filter core very soon, and liquid has all been soaked in cavernous sintered filter core inside, can evaporate on tens times the area obtaining than increasing in the past; Therefore greatly reduce the evaporation thermal resistance of evaporator section, improved the overall efficiency of heat pipe.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
