The specific embodiment
The utility model " Z " type heat pipe heat radiation LED illuminating lamp is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, Fig. 2, " Z " type heat pipe heat radiation LED illuminating lamp, be to constitute by: sunshading board 1, drive end bearing bracket 2, rear end cap 3, lamp body 4, " Z " type heat pipe I 5, fin 6, " Z " type heat pipe II 7, be respectively equipped with drive end bearing bracket 2 and rear end cap 3 at the two ends of lamp body 4,12 natural heat dissipation sheets are set on the drive end bearing bracket 2,12 natural heat dissipation sheets and lamp stand link slot are set on the rear end cap 3, and drive end bearing bracket 2 and rear end cap 3 adopt the aluminium punching press to make.On lamp body 4, be provided with " Z " type heat pipe I 5 and " Z " type heat pipe II 7, on " Z " type heat pipe I 5 and " Z " type heat pipe II 7, fin 6 be set, be provided with sunshading board 1 on the top of lamp body 4.
See Fig. 3, Fig. 4, " Z " type heat pipe I 5 and " Z " type heat pipe II 7 are made up of two kinds of forms, and a kind of is the diameter difference of double hose " Z " type heat pipe I 5, and another kind is that the diameter of double hose " Z " type heat pipe II 7 is identical.Different structures causes different effects and heat dispersion.
The utility model has made full use of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, is delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, and its capacity of heat transmission is hundreds of times of any known metal capacity of heat transmission.Make people change the heat dissipation design thinking of traditional LED light fixture, adopt our " Z " type hot pipe technique to make the LED light fixture under the situation of low wind speed, no air quantity, can obtain promising result equally, make that the problem that does not rely on traditional heat-dissipating is well solved.Its lamp body appearance, installation direction, anglec of rotation limitation is very little.Broken away from tradition " I type straight tube ", " ring-like pipe " heat pipes such as " U type pipes " relies on gradient merely, and vertical ventilation obtains the unicity of better radiating effect.
Why can heat pipe have so good capacity of heat transmission from thermodynamic (al) angle? the heat absorption of object, heat release are relative, and be every when having temperature difference to exist, and heat just must occur from the phenomenon of high temperature to the transmission of low temperature place.Three kinds of modes from the heat transmission: radiation, convection current, conduction, wherein the heat conduction is the fastest.Heat pipe utilizes sweat cooling exactly, makes that heat pipe two ends temperature difference is very big, and heat is conducted fast.General heat pipe is made up of shell, imbibition core and end cap.Inside heat pipe is to be pumped into negative pressure state, charges into suitable liquid, and this boiling point of liquid is low, easily volatilization.Tube wall has the imbibition core, and it is made of the capillary porous material.Heat pipe is an evaporation ends for one section, other one section is condensation end, when one section of heat pipe is heated, liquid in the capillary evaporates rapidly, and steam flows to an other end under small pressure differential, and discharges heat, regelation becomes liquid, liquid flows back to evaporator section along porous material by the effect of capillary force again, and so circulation is more than, and heat reaches an other end by heat pipe one end.This circulation is carried out fast, and heat can be come by conduction continuously.
The utility model " Z " type heat pipe heat radiation LED illuminating lamp, lamp body 4 have adopted 360 ° of constructed of aluminiums and " Z " type heat pipe I 5 and " Z " type heat pipe II 7 to combine closely, and lamp body basket dress heat pipe excircle dimension can be slightly smaller than the shell structure of heat pipe excircle dimension.Can adopt different materials, as copper, aluminium, carbon steel, stainless steel, steel alloy etc. according to different needs for " Z " type heat pipe and fin.Tube head employing direct spinning on spinning machine forms, and it is aesthetic in appearance, and intensity is good, the material saving and labour saving, is a kind of good tube head form.
