Technical Field
The utility model belongs to the technical field of display device and specifically relates to laser display device.
Background
Present laser display equipment, the power of light source accounts for the overwhelming majority of complete machine power, the heat that the light source during operation produced is very high, in time dispel the heat, the life-span of the good or bad influence light source of radiating effect, therefore laser display equipment's heat abstractor is extremely important, current heat abstractor is mostly cooling fan, blow to the light source with the fan and cool off, owing to compromise the noise problem, the fan speed is limited, thereby make the amount of wind that the fan produced limited, moreover the heat transfer area of light source itself is little, and then make this kind of cooling method radiating effect not good, make the temperature of light source too high, often take place troubles such as shut down.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a laser light source radiator that the radiating effect is better is provided.
The utility model provides a technical scheme that its technical problem adopted is: the laser light source radiator comprises a light source heat exchanger and a fan heat exchanger, wherein the light source heat exchanger is communicated with the fan heat exchanger through an L-shaped heat pipe, a fin of the light source heat exchanger is perpendicular to a fin of the fan heat exchanger, and a recess communicated with the front end face of the light source heat exchanger is formed in the light source heat exchanger.
Further, the top of the light source heat exchanger is stepped.
Furthermore, the L-shaped heat pipe penetrates through the fan heat exchanger, and the right end face of the L-shaped heat pipe exceeds the right side face of the fan heat exchanger.
Further, the LED lamp also comprises an ear plate which is fixed on the top of the recess of the light source heat exchanger.
Furthermore, a positioning hole is arranged on the fan heat exchanger.
Furthermore, threaded holes which are uniformly distributed are formed in the fan heat exchanger.
The utility model has the advantages that: compared with the prior method of radiating the laser light source only by adopting the fan, the utility model comprises a light source heat exchanger and a fan heat exchanger, the light source heat exchanger is communicated with the fan heat exchanger through an L-shaped heat pipe, the light source heat exchanger is directly contacted with the light source through radiating silicone grease, the heat exchange area of the light source is increased, the light source heat exchanger can directly exchange heat with air, heat can be transferred to the fan heat exchanger through the heat pipe, forced convection is blown to the fan heat exchanger by the fan, the heat transferred to the fan heat exchanger can be rapidly taken away, the temperature difference between the fan heat exchanger and the light source heat exchanger is kept stable, the heat flow transferred from the light source heat exchanger to the fan heat exchanger through the heat pipe is stable, the air quantity required by the fan heat exchanger for radiating is stable, the power of the fan is stable, the speed of the fan does not need to, and the noise of the whole machine is smaller.
