Hole abuts together, and the linear expansion coefficient of the radiator is less than the linear expansion coefficient of the heat conducting sleeve.When light is observed not
It is dazzling, diode illumination, power saving.
But the requirement of green laser diode pair environment temperature is especially high, when environment temperature be less than 25 DEG C when its brightness drop
It is low, during higher than 30 DEG C brightness equally reduce, therefore when green laser diode uses should consider heat dissipation consider again plus
Heat especially uses in winter, and environment temperature is than nearly -25 DEG C of temperature that is relatively low, having some national, to using the laser two of green
The product of pole pipe does not work at all, if it is that can not work to laser diode heating product not design heating structure on product
, at present to there are two types of the mode of heatings of laser diode, one kind is heating tape to be wound on laser diode and then by laser
The mode that diode is installed on radiator is heated, which can lead to laser diode when being radiated
It radiates bad, so the serious heating for being unsuitable for laser diode.Another kind is that a power resistor is placed on two pole of laser
Radiator is heated in the spreader surface of pipe, laser diode is then transferred heat to by radiator, due to dissipating
Its heat of the heat dissipation on hot device surface passes to very very long during the starting of laser tube green laser diode, rising in low temperature environment
Dynamic duration（Laser diode is heated to the duration of 25 DEG C or more progress normal luminous）Want at least 30 minutes or more namely

It is separated.Heat during heating can be flowed to largely at where laser tube, play the role of improving heating effect, and to heat dissipation
When obstruction lack.
Preferably, the Chip-R is arranged on side of the heat-conducting substrate far from the laser tube.It can be both
Ensure the heat transfer of Chip-R to heat-conducting plate but enable to Chip-R presence do not interfere heat-conducting plate and laser tube it
Between heat transfer effect.It needs to heat laser tube when temperature is less than 25 DEG C, laser tube is pacified under shrinkage effect at this time
Hole is filled with clearance fit is formed between laser tube, the heat that can be effectively prevented laser tube is further lost in and plays raising
The effect of the efficiency of heating surface.
Preferably, one end of the heat conducting sleeve and one end of radiator are all sealed against on sealing plate, the heat conduction
The other end of set and the other end of radiator are sealed connected together by annular reservoir, the heat conducting sleeve, sealing plate, heat dissipation
Form annular seal space between device and annular reservoir, the annular seal space is with annular reservoir connection and in gravity or annular reservoir
Insulation liquid in the lower annular reservoir of elastic shrinkage effect can be flowed in annular seal space.Since shrinkage is acted on when less than 25 DEG C
It can cause to generate gap between heat conducting sleeve and laser tube mounting hole and reduce the heat-conducting effect between heat conducting sleeve and radiator and rise
To the effect for improving heating effect, insulation liquid, which is filled into the gap to play, at this time further improves insulation effect so that heating
Effect is more preferable.When temperature needs heat dissipation higher than 25 DEG C or 30 DEG C, under heat expansion effect heat conducting sleeve and laser tube mounting hole it
Between push against together, push against during the adiabatic liquid between heat conducting sleeve and laser tube mounting hole squeezed out and be stored in annular storage
In liquid capsule.Heating effect during heating can be further improved.
