Description

Vane heat dissipating system

The utility model relates to the i.e. heat-pipe type radiator below 40 ℃ of a kind of normal temperature, especially uses heat pipe principle and forms vane heat dissipating system with imitation plant leaf blade morphosis.

At present, known heat pipe is a kind of heat transmitter, it utilizes working medium to absorb the rising heat transfer of latent heat phase transformation, has thermal conductivity than fast hundred times of solid good thermal conductors, it is long that self has a narrow range of temperature apart from conducting heat, utilize this principle, on heat pipe outer wall, form the radiating fin of many same good thermal conductor materials, attempt to discharge latent heat formation heat-pipe radiator by enlarging area of dissipation at normal temperatures, but enlarge area of dissipation in any case, the solid conduction heat discharges the speed of the speed of latent heat well below the transpiration conduction, the high rotating speed fan of civilian dress forced heat radiation, and noise is very big, restricted by this, heat-pipe radiator is easily influenced by ambient temperature, when environment temperature is high relatively, is just putting when being badly in need of heat radiation, its heat-sinking capability but sharply weakens, generally be limited in the environment below 30 ℃, cause on performance heat-pipe radiator superior unlike common solid heat loss through conduction device, tracing it to its cause is existing heat-pipe radiator and fails thoroughly to utilize high performance rising conduction principle.

The purpose of this utility model provides a kind of vane heat dissipating system, correct the structural form of existing heat-pipe radiator, make the speed of the rising conduction of working medium not be subjected to the slow-footed restriction of solid conductive heat, form the inner surface that direct transpiration is transmitted to radiator shutter, directly discharge latent heat to the external world, along with the formation that weakens condensation that working substance steam is pressed, bring up the structural system that helps the circulation of working medium evaporative condenser, realize high-performance conduction and distribute heat.

The purpose of this utility model is achieved in that the sandwich of utilizing the foliaceous sealing that the heat conduction light sheet material makes, its basic comprising is the sealed heat-dissipating layer, the condensation stratum reticulare, this three laminations of sealed heat-dissipating layer, Zhong Jian condensation stratum reticulare can be the multilayer of different meshes as required, all there is spatia in each layer, on the sealed heat-dissipating layer of each sheet blade, the vein of each the tool function that forms by halfpipe protuberance of distributing, form the admission arteries and veins in the vapour pressure eminence, along with steam drop forms the diffusion arteries and veins, assemble formation backflow arteries and veins with condensation, all there is a side opening at base portion or middle part at each sealing blade, and side opening continuous next blade, therefore some blades can be with parallel, radiation, overlapped way combines, constitute the public basic chamber of a totally-enclosed, base is being got in touch with condensation stratum reticulare in all blades in the chamber, it is the be heated circulation center of rising heat radiation condensing reflux of working medium, the base chamber, spatia, vein constitutes the structural system of working medium circulation, a large amount of blade outer surfaces is a radiating surface, constitute vane heat dissipating system thus, the position that receives heat in basic chamber is the sidewall that is heated, the wall inner face is the rising interface of working medium, the wall outside is the side that is heated, the high power device that can compoundly need refrigeration or heat radiation, utilize the aligned gaps between the blade to form the convection current air channel, need not fan just can dispel the heat effectively, also can install fan assistance heat radiation, reach the purpose of rising conduction of high-performance and direct distribute heat thus.

Owing to adopt such scheme, imitation plant leaf blade morphosis, realize that up hill and dale transpiration is conducted and large tracts of land is directly dispelled the heat, promptly bring up comprehensive working medium loop structure system, therefore had powerful biography, heat-sinking capability, can be below 40 ℃ in environment temperature, be applied in efficiently in the heat radiation of thermoelectric refrigeration of semiconductor and computer CPU or large power, electrically device, can really finish refrigeration and the heat radiation process of not having the machinery motion, also can install slow-speed of revolution fan, noiselessness or the ground work of low noise long-life.
