Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present utility model provides a technical solution:
A high-power LED irradiation head heat dissipation air duct structure comprises an irradiation head main body 1;
The irradiation head main body 1 includes: a heat sink 10, an air deflector 20, a fan 30, an LED chip 40, and a housing 50;
The radiator 10, the air deflector 20, the fan 30 and the LED chip 40 are detachably arranged in the shell 50; the air deflector 20 is inserted into the guide groove 12 of the fin 11 of the radiator 10, and the fan 30 is fixed on the air deflector 20; the LED chip 40 is mounted on the base 13 of the heat sink 10.
Specifically, the heat sink 10 is mounted on the front plate 51, the rear plate 52, the left plate 53, and the right plate 54 of the housing 50, then the LED chip 40 is mounted on the base 13 of the heat sink 10, then the fan 30 is fixed on the air guide plate 20, and inserted into the guide groove 12 of the heat sink 10 together, and finally the upper plate 55 and the lower plate 56 are fixed.
The upper plate 55 is provided with an air inlet, and the front plate 51 and the rear plate 52 are respectively provided with an air inlet 57 and an air outlet 58, thereby forming a special air duct.
Furthermore, the fan 30 provided in the present embodiment is a ball fan, which has a more compact structural design and a smaller volume, and can be better installed inside the irradiation head main body 1;
Specifically, the high-power LED irradiation head heat dissipation air duct structure can be used together with LED chip heat dissipation, and LED chip heat dissipation is mainly related to a substrate and a circuit selection process, and heat generated by an LED chip can be finally dispersed into air through a lamp shell because any LED can be used for manufacturing a lamp. The heat capacity of the LED chip is small if it does not dissipate heat well, so that if some heat is accumulated, the connection temperature of the chip is rapidly increased, and if it is operated at high temperature for a long time, the lifetime is rapidly shortened. But this heat must travel several ways to direct the air that the chip actually reaches the outside. In particular, the LED chip may generate heat from the metal heat block, generating heat from the solder to the PCB on the aluminum substrate, through the thermally conductive adhesive to the aluminum heat sink. Thus, LED lighting includes both heat spreading and heat spreading. The cooling mode of the LED housing depends on the size and the use position of the power supply.
The high-power LED irradiation head heat dissipation air duct structure provided by the embodiment can be widely applied to the field of LED irradiation, such as an LED irradiation lamp for printing and curing, medical sterilization, illumination and bonding of LED lamp use places.
In view of the above, the present utility model has the above-mentioned excellent characteristics, so that it can be used to improve the performance and practicality of the prior art, and is a product with great practical value.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
