The device is convenient to produce, simple in technology, low in cost, strong in practicability and good in working performance. Compared with the traditional heat pipe, the heat pipe of the type has smaller capillary equivalent radius and greater capillary force. Therefore, the heat pipe with spunlaced non-woven fabric and wire mesh capillary tissue structure can reduce the entire thermal resistance of the whole heat tube system, improve the heat transfer efficiency of the system, and is novel and high-efficiency.
Description
Technical field
The utility model relates to a kind of device of technical field of heat exchange, specifically is a kind of heat pipe with spunlace non-woven cloth and silk screen capillary structure structure.
Background technology
Along with the function of power electronic equipment is more and more perfect, its volume is also more and more littler, at the inner high heat flux that produces of power electronic equipment the reliability of installing is caused very big threat.Statistics to the power electronic equipment failure cause shows. and since the inefficacy that causes of high temperature in all electronic equipments lost efficacy shared ratio greater than 50%.Heat transfer problem even become the bottleneck of power electronic equipment to miniaturization development.Heat pipe then is an emerging technology that grows up along with the development of microelectric technique.Along with the increase of electronic component integration density, its dissipation that produces heat becomes difficult.Electronic component is except having the requirement maximum temperature, and the uniformity of temperature has also been proposed requirement.As a very promising technology, heat pipe is applied in the electronic component just, with the derivation rate of raising heat and the homogenising of temperature.Because its size is little, can reduce the dead volume in the running system, cut down the consumption of energy and reagent dosage, and response is fast, therefore wide application prospect is arranged.Therefore heat pipe has also become best radiator structure to select, because inside heat pipe is provided with capillary structure and the working fluid that is used for conducting heat, by causing working fluid to convert gas phase state to after the heat exchange action, after conducting to heat on the radiator fast, with the exchange heat that absorbed to the radiator that is connected, change back liquid phase state again, be back to the original place by the capillary structure effect more at last, to carry out circulating heat conduction.
Find that through literature search present employed capillary structure can be divided into plough groove type, woven wire formula or metal sintering powder type to prior art.China Patent No.: ZL200720003522.2, patent name is the heat pipe pipe shaft structure with plough groove type capillary structure, adopt within it be formed with on the wall a plurality of along the axially extended groove of body, and auxiliary transmission body, auxiliary transmission body has plate and a plurality of steam channels that are located on this plate, and this plate cooperates the inwall of this tube body of heat pipe and attaches mutually, to reach the effect of the capillary force that increases the channel form capillary structure.Though, the capillary structure of plough groove type can be back to evaporator section by condensation segment fast by liquid, but the capillary structure capillary attraction of plough groove type is poor, the region area of evaporator section heating working medium is less, and the capillary structure that forms with groove destroys the capillary force of its groove easily in the molding process of the bend pipe of heat pipe or flattening.
Further retrieval is found, China Patent No.: ZL200820126677.X, and patent name is: sintered heat pipe comprises the metal body and is arranged at the metal powder sintered layer of inboard wall of tube body that two sections metal powder sintered layers are by the sintering zone is not spaced apart.Can reduce the surface area that heat pipe liquid contacts with steam, reduce the working media flow resistance.Though the formed capillary structure of woven wire formula or metal dust has good capillary attraction on heating end, the region area of bigger evaporator section heating working medium is arranged, allow evaporator section can absorb more heat energy.But the netted hole size decreases of silk screen has certain limit, and the capillary force that is produced still can't reach best heat-conducting effect.Therefore, how improving the defective of aforementioned structure heat pipe simultaneously, propose a kind of easy new heat pipe structure with low cost of making, is an effective way that solves existing heat dissipation problem.
The utility model content
The utility model provides a kind of heat pipe with spunlace non-woven cloth and silk screen capillary structure structure at the prior art above shortcomings, and is easily manufactured, technology is simple, with low cost, applicability is strong, and service behaviour is good, and such heat pipe is compared with conventional heat pipe, the capillary equivalent radius is littler, and capillary force is bigger, therefore can reduce the entire thermal resistance of whole hot-pipe system, the heat transfer efficiency of raising system is a kind of novel high-efficiency heat pipe.
The utility model is achieved through the following technical solutions, the utility model comprises: spunlace non-woven cloth, woven wire, heat pipe and working medium, wherein: spunlace non-woven cloth is fixedly set in the inwall of thermotube wall, and woven wire is arranged at the inboard of spunlace non-woven cloth, and working medium filling is in heat pipe.
Described working medium is the low boiling liquid refrigerant.
Compared with prior art, the present invention has following beneficial effect:
1, used the good spunlace non-woven cloth of capillary force to make the imbibition core, heat pipe capillary power has improved an order of magnitude, and heat exchange property strengthens, and has improved the heat conduction speed and the usefulness of heat pipe, and its maximum service rating is increased.
2, the silk screen heat pipe can only horizontal level or heating surface effective in following time.And this heat pipe does not have the strict directionality requirement of bringing-up section when using, and is applicable to any occasion.

Fig. 1 is the utility model longitudinal section.
Fig. 2 is the utility model sectional elevation.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises: spunlace non-woven cloth 1, woven wire 2, heat pipe 3 and working medium 4, wherein: spunlace non-woven cloth 1 is fixedly set in the inwall of thermotube wall 3, and woven wire 2 is arranged at the inboard of spunlace non-woven cloth 1, and working medium 4 is filled in the heat pipe 3.
Described spunlace non-woven cloth 1 is for containing the hydroscopicity nonwoven fabric of hydrophily viscose composition, and the model that adopts in the present embodiment is 3070 types (30% terylene, 70 viscoses), the water imbibition extra-heavy.
Described silk screen 2 is a stainless steel cloth.
Described heat pipe is shaped as cylindrical cross-section, supports spunlace non-woven cloth by woven wire it is close to the heat pipe wall, can carry out bending according to the difference of applying working condition, and the outer wall of evaporator section and condensation segment can come augmentation of heat transfer by brazing fin.
The liquid working substance that present embodiment has by setting in the heat pipe of spunlace non-woven cloth and silk screen capillary structure structure undergoes phase transition, and adds that the capillary suction force that spunlace non-woven cloth produces makes whole flat-plate heat pipe be able to circular flow.
