Description

The thermal-arrest heat pipe

The utility model relates to a kind of thermal-arrest heat pipe, refers in particular to a kind of by heat collector that collecting end of heat, hot span line and outer link constituted.

Conventional contact area for increase heat pipe and thermal source, focus on heat pipe is embedded in the collector metal pipe (sink), utilize collector metal device (sink) that the heat of thermal source is reached on the heat pipe, reach on other radiators to reach heat-conducting effect by the heat of heat pipe again thermal source.Because of collector metal device itself and the non-same material of heat pipe, make the conduction of heat can't be quick, and the thermograde of collector metal device itself be bigger, promptly the temperature difference in the cold junction of collector metal device and hot junction is bigger, and heat-conducting effect is relatively poor naturally.

The purpose of this utility model is to propose a kind of by collecting end of heat, the thermal-arrest heat pipe that hot span line and outer link are formed, its thermal-arrest and heat-conducting effect improve greatly, and heat-collecting capacity and heat conduction amount can be in parallel side by side with several thermal-arrest heat pipes because of its demand, connect or overlapping use, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is: it utilizes its high efficiency thermal-arrest of heat pipe and heat conduction function and is applied to the including on the high thermal source product of demand heat radiation, its composition includes three parts, one is collecting end of heat, two is hot span line, three is outer link, this three part is formed by heat pipe (or claiming Super-conductive conduit) machine-shaping, collecting end of heat connects thermal source, heat is reached span line through collecting end of heat to be connected with other radiator links by outer link again, wherein that collecting end of heat machine-shaping embayment is back-shaped, or spiral shape, or helical spring shape, with the contact area of increase with thermal source, to reach the high efficiency thermal-arrest, thermal source heat energy is transferred to other radiators and energy is efficient.

So-called herein heat pipe (heat pipe) is meant copper, aluminium or other metal tube, but its pipe includes the liquid or the pure water of high rate heat transport, or contain particulate metal composition (as metals such as yttrium, barium), or other hot superconduction materials, the high speed concussion and the friction that produce when utilizing its molecule to be heated, and make thermal source with fluctuation mode flash heat transfer, so heat pipe is more a lot of soon than the heat conduction speed of general fin, so be called Super-conductive conduit again.Because of heat pipe that heat is very short by the transmission time that its hot junction reaches its cold junction, so the temperature difference of hot junction and cold junction is also little.Equally, the temperature difference everywhere of thermal-arrest heat pipe of the present utility model is also little, and the molding heat conduction pipe of the collecting end of heat of thermal-arrest heat pipe of the present utility model is replication shape, spiral shape, helical spring shape, can increase with heat source-contacting surface long-pending, because increase with heat source-contacting surface is long-pending, thermal source heat energy can be directly conducted to heat pipe without other media, to reach best thermal-arrest and thermal conduction effect.Replication shape can be combined side by side for single serpentine or a plurality of " U ", serpentine and " U " combined side by side, a plurality of wriggle combined side by side; Spiral shape can be rectangle spiral shape, polygon spiral shape, circular spiral shape, oval spiral shape, meander shape spiral shape, cone rectangle spiral shape, conical spiral shape, also can be according to the suitable crooked or distortion of processing of the long-pending demand of collecting end of heat and heat source-contacting surface, or according to heat-collecting capacity and heat conduction amount demand with a plurality of thermal-arrest heat pipe parallel side by side, connection or overlapping application.

Advantage of the present utility model is: be all identical material because heat pipe is directly connected with other radiator links by outer link through hot span line from the collecting end of heat that connects thermal source again, so its collecting end of heat has a narrow range of temperature with outer link, and collecting end of heat and heat source-contacting surface are long-pending to be increased, so thermal-arrest and heat-conducting effect improve greatly.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.

As shown in Figure 2, the thermal-arrest heat pipe forms 3, it uses undressed heat pipe 1, as shown in Figure 1, with heat pipe machine-shaping is serpentine thermal-arrest heat pipe 31, then can increase contact area with thermal source 2, whole thermal-arrest heat pipe is divided into three parts, be collecting end of heat 311, hot span line 312, outer link 313, thermal source heat energy directly is connected with the outer link 511 of the radiator of other radiators 5 via outer link 313, and reach thermal-arrest, heat conduction and radiating effect, the collecting end of heat 311 of this thermal-arrest heat pipe 3 is single serpentine 31, its collecting end of heat 311 can be done various variation because of the demand of collector area and be shaped to replication shape, spiral shape, helical spring shape, as the single serpentine 31 of Fig. 3 A, Fig. 3 B serpentine 31 forms 4 with the combined side by side thermal-arrest heat pipe that is combined into of " U " 32, Fig. 3 C serpentine 33 is combined side by side with " U " 32, many serpentine of Fig. 3 D 33 are combined side by side, many " U " 32 of Fig. 3 E to Fig. 3 G are combined side by side, Fig. 4 A rectangle spiral shape 34, the circular spiral shape 35 of Fig. 4 B, Fig. 5 helical spring shape 36 can increase several times to tens times collector area.

The design of the utility model thermal-arrest heat pipe, because directly being connected with other radiator links by outer link through hot span line from the collecting end of heat that connects thermal source again, heat pipe is all identical material, so its collecting end of heat has a narrow range of temperature with outer link, and collecting end of heat and heat source-contacting surface are long-pending to be increased, so thermal-arrest and heat-conducting effect improve greatly.Another characteristics of the present utility model, can be because of the demand of heat-collecting capacity and heat conduction amount is in parallel side by side with a plurality of thermal-arrest heat pipes, connection or overlapping application, shown in Fig. 6 A, Fig. 6 B, Fig. 6 C and Fig. 6 D to increase the contact area with thermal source, maybe can be according to the increase in demand heat pipe quantity of thermal source heat-collecting capacity and heat conduction amount.Also the heat pipe of collecting end of heat can be shaped to spiral shape 34, serpentine 31 or other shapes (as Fig. 7 A, Fig. 7 B) earlier, again according to collecting end of heat and the suitable crooked or distortion of processing of the long-pending demand of heat source-contacting surface.

More than be detailed description of the present utility model, use the utility model to remove processing simply, cost is cheap, it is also easy to install, and thermal-arrest and heat-conducting effect are very good, fully meet industrial economic benefit, and help the thermal-arrest of demand thermal source heat radiation product and the solution of heat conduction problem.The utlity model has the value that creativity, practicality and industry are utilized.
