Technical field
What the present invention relates to is a kind of device of heat enginnering technical field, specifically is a kind of micro-channel flat plate heat pipe of metal wire structure.
Background technology
Flat-plate heat pipe is a kind of device that utilizes Working fluid phase changing to transmit heat, it has the changeability of higher thermal conductivity, heat flow density, invertibity, thermal diode and the thermal switch performance of direction of heat flow, good isothermal, is the ideal device of space station, modern communication satellite, spaceship and electronic equipment cooling.Flat-plate heat pipe is to rely on working medium to absorb heat and carburation by evaporation in heat pipe evaporator section, the steam that produces enters condensation segment through steam channel, steam is emitted heat and is condensed into liquid in condensation segment, condensation water is finished systemic circulation under the effect of the capillary suction force that the inside heat pipe capillary structure produces and get back to evaporator section.The structure of the flat-plate heat pipe of prior art all is conduit type or liquid sucting core structure, and so-called liquid sucting core structure generally is to be processed by sintering metal, and wire netting and fibre web are also arranged; Traditional conduit type structure then is to be rectangle or trapezoidal structure by the cross section that machining forms.
Through the literature search of prior art is found, 1. Chinese patent application number: 01131198.3, name is called: flat type loop type heat pipe; 2. Chinese patent application number: 01131199.1, name is called: flat type loop type heat pipe, the equal more complicated of the processing of above-mentioned two kinds of structures, evaporator section conduit bottom equivalent capillary radius is bigger, and the exchange capability of heat of heat pipe is restricted, and processing cost is than higher.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of micro-channel flat plate heat pipe of metal wire structure is provided.Compare with the heat pipe of tradition processing micro-channel structure, capillary conduit equivalent radius is littler, and capillary force is bigger, therefore can reduce the entire thermal resistance of whole hot-pipe system, improves the heat transfer efficiency of system.
The present invention is achieved by the following technical solutions, the present invention includes: base plate, loam cake, sealing forms a hollow housing between base plate and the loam cake, to establish the diameter that is parallel to each other be the wire of 1-3mm to folder in housing, the curved surface triangle slit that forms between wire and base plate, the loam cake is the liquid film district, and the curved surface quadrilateral-shaped apertures between adjacent wire and base plate, the loam cake is a steam channel.
Whole flat-plate heat pipe is divided into successively: evaporator section, adiabatic section and condensation segment, evaporator section length are 30-50mm, and adiabatic section length is 100-150mm, and condensation segment length is 30-60mm, and the outside, adiabatic section is provided with heat-insulating material.
The adjustable range of described spacing wiry is zero to a wire diameter, and wire quantity is smaller or equal to 40.
Described base plate adopts bolt to be connected with loam cake, adopts rubber weather strip sealing or welded seal.
Described material wiry is copper or stainless steel etc.
The core of this heat pipe is exactly that the tiling of inner employing parallel wire forms, replace traditional conduit type structure (cross section that forms by machining is rectangle or trapezoidal structure), wire and form curved surface triangle slit (liquid film district) up and down between the two boards, it is generally acknowledged that in this case the corner cut that forms between wire and base plate, the loam cake equals zero, be that capillary conduit equivalent radius equals zero, this geometry has maximum capillary force, therefore can reduce the entire thermal resistance of whole hot-pipe system, improve the heat transfer efficiency of system.
Curved surface quadrilateral-shaped apertures between adjacent wire and base plate, the loam cake is a steam channel.Regulate the gap between the wire, to change the size of steam channel.Quantity wiry is many, and then micro-channel quantity is many, helps increasing capillary force, reduces thermal resistance, but along with the steam channel sectional area reduces, has reduced maximum heat exchange power again.Therefore, exist a best metal silk spacing, make heat pipe have best heat transfer characteristic.The adjustable range of spacing can be from zero to a wire diameter.General desirable distance continuously and spacing equal two kinds of size design of wire diameter.Change wire diameter and also can regulate the heat pipe heat exchanging characteristic, diameter helps improving the peak power of system when big.Diameter hour helps reducing thermal resistance.
The present invention has following beneficial effect: adopt metal wire structure to replace traditional conduit type structure, heat pipe capillary power is improved, and reduces the entire thermal resistance of whole hot-pipe system, improves the heat transfer efficiency of system; Processing is simple, need not special equipment, has reduced cost of manufacture.
