The invention discloses a heat radiating system of the whole machine of a laser projector. A first wind inlet and a second wind inlet are respectively arranged on both sides of an optical engine module of the heat radiating system; a heating module not provided with a heat radiating fan is arranged near the first wind inlet; a heating module provided with the heat radiating fan is arranged near the wind outlet of the whole machine; a laser light source module is provided with a priority heat radiating fan and a special wind outlet and is assisted with a necessary wind inductive structure so that a first part of wind flow which enters from the second wind inlet is discharged by the priority heat radiating fan from the special wind outlet; the rest part of wind flow which enters from the second wind inlet and the entire wind flow which enters from the first wind inlet are discharged by the heat radiating fan from the wind outlet of the whole machine, so as to prevent the laser light source module from being heat for the second time and ensure that the laser light source module works stably under lower working environment temperature; the heat radiation of the rest parts of the wholemachine can also meet requirements; energy is saved; and the heat radiating system is mainly applied to the laser projector.
Description
technical field [0001] The invention relates to a whole machine cooling system of a projector, in particular to a whole machine cooling system of a laser projector. Background technique [0002] Laser projectors use red, green and blue primary color lasers with high color saturation as the display light source. As a highly directional light source with a crystal / semiconductor structure, a laser light source is a solid-state light source and is very sensitive to temperature. Generally, the standard operating temperature of the laser light source module is required to be 25°C, and the operating temperature range is -10°C to 50°C. At present, when the output wavelength of the laser is stable, a thermoelectric cooler (TEC) is often used to control its temperature with high precision to ensure the normal and stable operation of the laser. [0003] At present, in order to meet the temperature control requirements of the laser generator for projector products that use laser light ...
