Cooling system of projector bulb and projecting device by adopting same

Abstract

The invention relates to a cooling system of a projector bulb, which is characterized by comprising a thermotube conduction unit with a groove and a bulb unit, wherein the bulb unit is fixed in the groove of the thermotube conduction unit. The cooling system of the projector bulb transmits a part of heat produced by the bulb unit to other parts which have low temperature relative to the bulb unitthrough the thermotube unit; then the cooling system exhausts the heat through a radiator fan of the part or forced convection or radiation; therefore, the heat produced by the bulb is not intensively exhausted through a bulb fan cooling system, the aims of better dispersing heat and dispersing exhaust are achieved, the projector bulb has good radiation effect, the temperature of the whole projector is reduced, the material temperature in the projector is ensured to be in a stipulated range and the service life of the projector is prolonged; the temperature of a shell near the projector bulb is reduced so as not to scald hands; the temperature of the exhausted gas is reduced so as not to produce peculiar smell; and users can have good impression on the projector in use..

Description

【Technical field】 [0001] The invention relates to an image device, in particular to a projector bulb heat dissipation system and a projection device using the system. 【Background technique】 [0002] At present, with the increasing function and complexity of electronic products, the power consumption continues to increase, and the power loss is usually converted into a certain amount of heat energy. The miniaturization of electronic products requires a sharp increase in the heat flux density of the product (the amount of heat transferred through a unit heat transfer area per unit time), resulting in a rapid increase in the temperature of electronic products. Failure to dissipate heat effectively will seriously affect the reliability and use of the product life. As an electronic product, projectors currently use high-power bulbs to achieve high illuminance and generate a lot of heat, and the power consumption of bulbs accounts for a large proportion of the entire power consum...

Problems solved by technology

The miniaturization of electronic products requires a sharp increase in the heat flux density of the product (the amount of heat transferred through a unit heat transfer area per unit time), resulting in a rapid increase in the temperature of electronic products. Failure to dissipate heat effectively will seriously affect the reliability and use of the product life

As an electronic product, projectors currently use high-power bulbs to achieve high illuminance and generate a lot of heat, and the power consumption of bulbs accounts for a large proportion of the entire power consumption of the projector. The temperature of the casing is very high, it is easy to burn hands, the exhaust temperature of the bulb is too high, and the temperature of the materials in the machine is not within the specified range, which affects the life of the projector.
