Description
Technical field
The present invention relates to LED field of light fittings, a kind of top omnidirectional particularly, realizes the LED light fixture based on antigravity heat radiation of high-performance heat radiation under the cooling condition in bottom.
Background technology
Phase-change heat transfer is while utilizing the form of working medium to change, to carry out a kind of heat transfer type of heat absorption and release.Such as liquid refrigerant absorbs heat when vaporizing, when cooling, emit heat.Phase-change heat transfer is as a kind of latent heat exchange process, and not only heat-transfer intensity is large, and heat transfer efficiency is also very high, quantitatively can be than the large several orders of magnitude of general solid material heat conduction.In actual applications, be subject to the restriction of structure usually to occur bringing-up section in the above, cooling section situation below, at this moment, general liquid-sucking core adopting heat pipes for heat transfer efficiency will reduce greatly, heat transfer efficiency even reduces more than 80%, so the capillary force of liquid-sucking core and structure become the key that improves antigravity adopting heat pipes for heat transfer efficiency.
From existing achievement in research, LED radiator is made with aluminium or other solid materials, and its radiating efficiency is difficult to meet the demand that great power LED upwards irradiates.
Summary of the invention
