Description

Hot wing
Technical field
The utility model relates to a kind of phase-change heat transfer device, particularly a kind of hot wing (heat-wing).
Background technology
The phase-change heat transfer device is compared the solid metallic of high thermal conductivity coefficient; Have higher equivalent thermal conductivity factor and the heat dispersion of Geng Jia; It relies on self inner liquid-working-medium phase transformation realization heat conduction, has advantages such as high-termal conductivity, good isothermal, is applied in the industry widely.At present, heat pipe and soaking plate are heat abstractors comparatively commonly used in the phase-change heat transfer device.
Referring to Fig. 1, typical heat pipe is made up of shell 11, capillary structure 12 and the phase transformation working media 13 that is sealed in the pipe.Fill with suitable phase transformation working media 13 after being evacuated in the making of heat pipe will be managed earlier usually, make to seal after being full of phase change medium 13 in the capillary structure 12 of being close to shell 11 inwalls.One end of heat pipe is an evaporating area 14, and the other end is a condensing zone 15.When heat pipe evaporating area 14 is heated; Liquid-working-medium 13 boil-off gas change into gaseous working medium 16 in the capillary structure 12; Gas passing hole channel 17 under differential pressure action flows to condensing zone 15; Condense into liquid working media 13 and emit heat, liquid working media 13 leans on capillarity to flow back to evaporating area 14 along capillary structure.So circulation, heat 18 constantly reaches condensing zone 15 from evaporating area 14, realizes radiating effect.But heat pipe is because its diameter is less relatively, and its vapor transmission is linear transfer mode, approximate one dimension, and the transmission duct of steam is less, liquid working media backflow width is shorter, make heat pipe too early reach heat transport limitation.
As the improvement of heat pipe, soaking plate comprises base plate, loam cake, capillary structure and working media, and the base plate zone line part of soaking plate is as evaporating area, and upper cover part is as condensing zone, and it is identical with the principle of heat pipe, and just the transfer mode of heat is different.At inside heat pipe, vapor transmission is the plane transfer mode, and approximate two dimension is compared with heat pipe, and the vapor transmission passage of soaking plate is bigger, liquid working media backflow wider width, so the isothermal performance of soaking plate is better than heat pipe.But,, cause the evaporating area center of soaking plate to make that the heat transport limitation value of soaking plate is lower than evaporate to dryness morning because soaking plate evaporating area center is longer to the distance at evaporating area edge.
Therefore, need the New-type phase change heat transfer unit (HTU) that a kind of vapor transmission passage of research and development is big, working media backflow width is wide, the isothermal performance is good, heat transport limitation is higher.
The utility model content
Short, the higher phase-change heat transfer device of heat transport limitation of distance that the purpose of the utility model is to provide that a kind of vapor transmission passage is big, working media backflow wider width, evaporating area central area arrive the evaporating area edge.
For realizing above-mentioned purpose, the utility model provides a kind of hot wing, comprising:
Two side panels and the frame that is connected side panel are to constitute the lamellar housing of a hollow;
The capillary structure layer of being close to inner walls; With
Be sealed in the phase transformation working media in the housing;
Wherein, the part at the edge of said side panel or the part of frame are as evaporating area, and said side panel or housing remainder are as condensing zone.
In another preference, the material of said housing is copper, aluminium, stainless steel metal or alloy or other highly heat-conductive materials.
In another preference; Said capillary structure layer can be powder sintered, silk screen, groove, fiber; Can apply or growing nano carbon wall, CNT, nano carbon microsphere, or coating, other nanoscales of growing, micron order organic or inorganic thin layers of molecules, or the mixing of aforementioned structure and material; Can single or multiple lift compound, and other can produce capillary structure.
In another preference, said phase transformation working media can comprise the mixture of water or other liquid, low-melting-point metal, nano carbon microsphere, other nano particles and aforementioned substances, or other produce the material of gas-liquid phase transition in the serviceability temperature scope.
In another preference, said two parallel to each other or almost parallels of side panel.
In another preference, said side panel can be rectangle or other arbitrary shapes.
In another preference, said hot wing greater than its upper width, also can be less than or equal to its upper width near the cross-sectional width of evaporating area.
In another preference, the inner appropriate vacuum degree of making of hot wing according to the mechanical strength of housing and the positive and negative pressure of required opposing, can be provided with between said two side panels and support or syndeton.
In another preference, the shape of said support or syndeton can be point-like, wire or sheet.
In another preference, said hot wing also can be provided with fin.
In another preference, on said hot wing and/or fin, can apply the black body radiation material.
In another preference, said hot wing also can be provided with the pipe that vacuumizes with topping up.
In another preference, said hot wing array is arranged on the thermal source.
Compared with prior art, the beneficial effect of the utility model is: the hot wing of the utility model is the lamellar hollow housing of a sealing, and the length and width of this hot wing is much larger than its thickness, so the vapor transmission passage of hot wing is bigger, can have good isothermal performance.The spacing of two side panels is minimum; The part at the edge that lamellar housing relative area is very little or the part of frame are as evaporating area; Contact with the thermal source surface,, avoided the evaporating area central area phenomenon of evaporate to dryness early so the evaporating area center is extremely short to the distance at evaporating area edge.Two side panels that the housing area is bigger so the area of condensing zone is very big, help dispersing and condensation of heat as condensing zone, and the backflow wider width of working media has strengthened the flow of liquid working media.This hot wing has improved heat transport limitation significantly, so that can obtain higher heat flow density.
