In recent years, projectors have been widely used in offices, entertainment venues, homes and schools. In order to better optimize the user experience, projector products are constantly evolving. However, while improving functions, it is necessary to effectively remove heat and maintain a stable temperature. , to ensure work efficiency.
According to the imaging principle of the projector, when the projector projects the input signal, it needs extremely high brightness. In order to ensure such a high brightness output, the projector must be realized by using a high-power light source. After a long period of work, a high amount of heat must be generated inside the machine. In addition to the heat generated by the projector’s light source, the projector’s power supply also generates a lot of heat when it is working. The heat generated by the projector bulb, imaging system, power supply, etc. is concentrated in the small space inside the machine. The high temperature generated by it not only affects the normal use of the projector, but also greatly shortens the service life of the internal components.
The heat dissipation structure of the projector includes a heat pipe, a plurality of fins arranged on the heat pipe, and a fan arranged on one side of the plurality of fins. One end of the heat-conducting pipe is fixedly connected to the light source side of the main body of the projector, and the other end is arranged away from the main body of the projector. A plurality of fins are fixedly arranged at one end of the heat-conducting pipe that is far away from the main body of the projector. The fan is electrically connected to the main body of the projector for the purpose of Drive air flow to reduce the temperature of the fins. The heat generated by the main body of the projector can be transmitted to the fins through the heat conduction pipe, and then the temperature of the fins can be lowered by driving the air flow through the fan. In this way, the heat dissipation of the projector is accelerated, and at the same time, the occurrence of the problem that high-temperature air stays near the main body of the projector and affects the normal operation of the projector is avoided.
If the projector is used in areas with high temperature all the year round, the fan alone is not enough to dissipate heat. Therefore, many companies have modified the fans installed inside the projector, including heat dissipation methods, heat dissipation materials, etc., to fundamentally solve the problem that the projector cannot be continuously work problem.
The thermal conductive silicone gasket is soft, thermally conductive and insulating, especially its compressibility is good, and the thickness can be adapted to the spatial range of different smart projectors, and the controllability is good.
The thermally conductive silicone sheet is well filled between the fins of the projector’s heat-conducting tube and the cooling fan to achieve a seamless connection between the heat source and the cooling fan, reducing the thermal resistance of the contact surface between the heating element inside the projector and the cooling fan, perfectly and effectively The heat is transferred out, keeping the projector at a stable temperature and ensuring its working efficiency.
