Abstract
The utility model provides a radiation mechanism of a projector. The radiation mechanism of the projector comprises a projector body, a projection lens, an optical machine, a DMD, a DMD radiation fin, an optical switching mirror, a first radiation fin, a second radiation fin and a fan module, wherein the projection lens, the optical machine, the DMD, the DMD radiation fin, the optical switching mirror, the first radiation fin, the second radiation fin and the fan module are arranged on a bottom plate of the projector body. The projection lens is arranged at the front end of the optical machine. The DMD is arranged between the optical machine and the DMD radiation fin. The optical switching mirror is arranged on one side of the optical machine. The front end of the optical switching mirror is provided with an LED red light. The rear end is provided with an LED blue light. The side which is away from the optical machine is provided with an LED green light. The first radiation fin is arranged to be adjacent to the LED blue light. The second radiation fin is arranged on one side of the fan module. The LED red light and the LED green light are connected with the second radiation fin respectively through a heat conduction pipe. According to the utility model, the radiation efficiency of a projector optical source module such as the optical switching mirror and the like is improved.
Description
[technical field]
The utility model relates to a kind of cooling mechanism of projector.
[background technology]
At present, along with function and the complicacy of electronic product improves day by day, power consumption constantly increases, and the loss of power is converted to certain heat usually.The miniaturization of electronic product requires to make again the heat flow density of product sharply increase, and causes the temperature of electronic product to improve rapidly, affects reliability and the serviceable life of electronic product.In projector, it is particularly outstanding that the problem that heat flow density sharply rises shows.According to the image-forming principle of projector, after the three primary colours light that is sent by the light source module, then light is emitted to according to the requirement of signal by DMD digital micro-mirror sheet devices and form image on screen.In order to obtain the brightness output of high lumen, must realize by powerful light source module, particularly with the projector of LED as the light source module, be therefore the key content of projector's design to the heat dissipation design of light source of projector module.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of cooling mechanism of projector, can improve the radiating efficiency that the light source of projector module namely closes light microscopic etc.
The utility model is achieved in that
a kind of cooling mechanism of projector, comprise a projector body, and be arranged on a projection lens on the base plate of projector body, one ray machine, one DMD, one DMD radiating fin, one closes light microscopic, one first radiating fin, one second radiating fin, one fan module, described projection lens is arranged on the ray machine front end, DMD is arranged between described ray machine and DMD radiating fin, describedly close the side that light microscopic is arranged on ray machine, the described front end that closes light microscopic is provided with a LED red light, the rear end is provided with the blue lamp of a LED, a side away from ray machine is provided with a LED green light, the adjacent setting of the blue lamp of described the first radiating fin and LED, described the second radiating fin is arranged on a side of fan module, described LED red light and LED green light are connected to the second radiating fin by a heat pipe respectively.
The utility model has the advantage of:
Be provided with the adjacent setting of the blue lamp of a DMD heating radiator, described the first radiating fin and LED after DMD, the heat of DMD and the blue lamp generation of LED effectively can be dispelled the heat; In addition, described LED red light and LED green light are connected to the second radiating fin by a heat pipe respectively, therefore the heat of LED red light and the generation of LED green light can be sent to and the fan module, dispel the heat by the fan module; In a word, radiating efficiency of the present utility model is high, and is effective.
[description of drawings]
