In one embodiment, as shown in Fig. 1 and Figure 10, described heat-conducting mechanism 400 comprises fin 410, described fin 410 is connected with described thermal insulation board 200, such as, described fin 410 is semiconductor heat-dissipating sheet 410, when described semiconductor heat-dissipating sheet 410 is energized, the heat of described fin 410 transfers to hot junction by cold junction, such as, described semiconductor heat-dissipating sheet 410 comprises first end and the second end, described first end is connected with described thermal insulation board 200, described second end is connected with described first end, when described semiconductor heat-dissipating sheet 410 is energized, described first end is by the heat absorption of thermal insulation board 200, and be transferred to described second end, the temperature of described thermal insulation board 200 can be reduced rapidly, it is worth mentioning that, carrying out heat radiation by described semiconductor heat-dissipating sheet 410 to described thermal insulation board 200 is active heat removal, when thermal insulation board 200 temperature is not high, also the heat of first end can be forced to be passed to the second end by energising, make the temperature of thermal insulation board 200 lower, and without the need to just dispelling the heat when thermal insulation board 200 temperature is higher, radiating efficiency can be substantially increased like this.
In order to improve radiating efficiency further, such as, as shown in Figure 10, four described semiconductor heat-dissipating sheets 410 are set, thus improve the radiating efficiency of heat-conducting mechanism 400, such as, described thermal insulation board 200 is square, four described semiconductor heat-dissipating sheets 410 are arranged at four angles of square thermal insulation board 200, or four described semiconductor heat-dissipating sheets 410 are arranged at four limits of square thermal insulation board 200, like this, four described semiconductor heat-dissipating sheets 410 can absorb the heat of thermal insulation board 200 equably, the heat of thermal insulation board 200 is distributed more even, thus make multiple described laser module 100 to obtain effective temperature-reducing, increase the service life.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
