Background technology
For solving various electric equipment element over-temperature problems, generally all on heater element, install heat abstractor additional, the high temperature that makes electronic component produce is led heat energy by heat abstractor to shed.And known heat abstractor system by wind flat and fin formed, the high temperature that is produced when electronic component is operated is gone out thermal conductance by fin by fan.Though this kind heat abstractor can provide the function of heat radiation, so form hot blast and come loopback to blow and reduce whole efficiency, and fan produces the noise puzzlement in the running and can't solve in electronic equipment internal.Therefore new improvement proposes a kind of heat pipe heat radiation structure, promptly installs heat pipe for thermal conductivity to outside heat sink on heater element.
Heat pipe is a kind of high efficiency hot conduction technique, and this technology is succeeded in developing in 1963 by the G.M.Grover of the U.S..Belong to a kind of heat transfer element, common heat pipe all is made up of shell, imbibition core and end cap, and preparation method is that inside heat pipe is pumped into negative pressure state, charges into suitable liquid then, and tube wall has the imbibition core, is made of the capillary porous material.Heat pipe one end is an evaporation ends, and an other end is a condensation end.When one section of heat pipe was heated, the liquid in the capillary evaporated rapidly, and steam flows to an other end under small pressure differential, and discharge heat, regelation becomes liquid, and liquid flows back to evaporator section along porous material by the effect of capillary force again, and so circulation is transmitted heat energy rapidly incessantly.
The heat pipe of use at present is all based on copper pipe, an ancient piece of jade, round, flat and with a hole in its centre is provided with sintered porous material or wire netting in this pipe, has with the existing problem that often takes place of using: capillary material comes off, the crooked postcapillary material deformation of heat pipe blocks, the body surface is on-insulated easily makes short circuit, heating own and needs shortcomings such as particular curve equipment could be shaped.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible insulate heat tubular construction, the heat pipe that promptly integrated composite bed body is made.
The purpose of this utility model is achieved through the following technical solutions.
The heat pipe that integrally formed composite bed body is made, be the hollow stratiform body that polymer composite is made, this composite bed body is followed successively by by the outside layer structure of hollow space: tubular fiber establishment net, coextrusion molten adhere layer, plastics or composite skin.
Two ends at this heat pipe suitable length can be connected the high heat transfer metal consent, form a kind of thermal insulation, electric insulation and can be to the heat transfer heat pipe of any direction bending.
The composite bed body that this co-extrusion modling is made can be made the structure of pipe shape, square tube type, flat tubulose etc. by different die orifice designs.
Described tubular fiber establishment net can adopt the braid of mineral wool, wire, macromolecular fibre or organic and inorganic composite fiber etc.
Described plastics or composite skin are made up of one or more layers high molecule plastic or composite, and this constituent is a material high temperature resistant, anti-aging and hot, electric insulation.
The high heat transfer metal consent that composite bed body two ends are connected, this metal consent is made up of the metal ridge of entity, porous or fin type structure in the direction of composite bed body, and the endothecium structure of the ridge of this metal consent and composite bed body is combined closely.The heat absorbing end of composite bed body or radiating end direction, the metal consent ridge can be made up of many fold sheet, tabular or column structure.
The heat pipe that the integrated composite bed body of the utility model is made can reach that capillary material does not come off, not block after the heat pipe bending, has reduced the risk of short circuit.Simultaneously, heat pipe can be arbitrarily crooked, with the design of close fit device interior, makes it the heat sinking function that reaches best.
