Description
[technical field]
The utility model is about a kind of integrated heat pipe radiator structure, relates to the heat pipe principle of hot conduction, condensation, heat radiation, is a kind of heat pipe radiator structure of high-power thermal source heat radiation.
[technical background]
Along with the lifting of electronic installation internal electrical components arithmetic speed and the increase of consumed power, the heat of corresponding generation also increases severely thereupon, for electronic building brick can be operated under normal working temperature, usually need set up a radiator on the electronic building brick surface, in time discharge the heat that electronic building brick produces, sharp increase along with caloric value, common air-cooled radiator can not be finished temperature requirements, the heat pipe radiator is widely adopted, and heat pipe is located on some radiating fins, in the hope of fully distributing the heat that electronic building brick produces fast.The combination of this kind heat pipe radiator is the end of heat pipe only with the contact-making surface of electronic building brick, and the area that is used to conduct heat is less, thereby radiating effect is unsatisfactory.
The drive principle of general heat pipe is: saturated hydraulic fluid in capillary is heated by external heat source in the evaporation part, because the pressure reduction that steam produces, steam is moved to the condensation part direction, carry out heat delivery, cool off again in the condensation part condensing, heat release, this moment, condensing driving hydraulic fluid was absorbed in the condensation part, reflux to the evaporation part again, the moving and reflux course circulation running of above-mentioned driving hydraulic fluid, thereby by the evaporation part constantly to the mobile heat of condensation part continuation.
The principal element that general driving hydraulic fluid moves is: amount of thermal conduction, pipe capillaceous are pressed, capillary is interior for driving the resistance transmitance that hydraulic fluid flows to, because viscosity restriction, capillary pressure restriction, conduction or overflow restriction and boiling limit, its performance also is restricted in addition.
The inner capillary structure that quickens the working media backflow of heat pipe is generally mesh at present, filler particles, sintered powder, groove or fiber hair fine texture, yet, all there are shortcomings such as the not enough or flow impedance of capillary tension is excessive in these known capillary structures, thereby cause the radiating effect of heat pipe bad, sintered powder capillary pressure capillaceous is big, therefore for the working fluid conveying capacity brilliance that is subjected to the gravitation drag effects, because the inconsistency of its pore direction, transmitance reduces, the pressure loss was big when the driving hydraulic fluid moved, particularly bigbore heat pipe, in order to improve conductivity, it is thick that sinter layer often reaches 1-2mm, though help the backflow of hydraulic fluid, but also produce very big thermal resistance, and it is bigger to make difficulty of processing.
Because vapor stream is reverse with the backflow of hydraulic fluid in the heat pipe, it is also bigger to produce mobile resistance, causes must producing mutual interference mutually between vapor stream and hydraulic fluid and the circulation that influences working media.
Therefore, how to provide a kind of radiating effect the good heat pipe construction of improving above-mentioned shortcoming, be problem to be solved in the utility model.
[summary of the invention]
The utility model proposes for the problem miniature and the heavy caliber heat pipe construction that solves single in the past capillary structure, multiple capillary pipe structure, its characteristics are: be provided with copper powder sintering structure, surface by the surface, evaporation part with groove structure and have concave-convex and soak into condensation part, the multilayer copper wire of structure and weave with one heart that column imbibition core, hydraulic fluid and radiating fin that twist forms form, inside is the high-effect integrated heat pipe principle radiator structure of vacuum state.
The evaporation part of the integrated heat pipe radiator structure of the utility model is provided with several protruding columns, its surface has copper powder sintering capillary structure, the crowning of evaporation part and multilayer copper wire be concentric to weave the column imbibition core that twist forms and fully contacts, the middle multiple tracks water conservancy diversion vapour groove that forms, vapor stream directly moves to the condensation part rapidly by water conservancy diversion vapour groove, the hydraulic fluid that the core of imbibition simultaneously refluxes directly transmits to the evaporation part rapidly by the top of evaporation part projection, effectively reduced thermal resistance, the vapour lock of evaporation part, be more conducive to hydraulic fluid and evaporate backflow rapidly.The multilayer copper wire weaves the column imbibition core that twist forms with one heart, and its space has the orthodromic, and transmitance is big, and the pressure loss was little when the driving hydraulic fluid moved, and was more conducive to hydraulic fluid and transmitted rapidly.The surface, condensation part has the structure that concave-convex can be soaked into hydraulic fluid, effectively reduces thermal resistance, the vapour lock of condensation part, is more conducive to rapid condensation.
Owing to adopted technique scheme, the integrated heat pipe radiator structure of the utility model has higher usefulness, is suitable for high-power thermal source heat radiation.
