Title:
HEAT DISSIPATION APPARATUS FOR COLOR WHEEL, LIGHT SOURCE MODULE, AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/107970
Kind Code:
A1
Abstract:
Disclosed are a heat dissipation apparatus for a color wheel, a light source module, and a projection system. The heat dissipation apparatus for a color wheel comprises a housing (2) having a circulation air passage therein, and an air exhaust apparatus (3), a color wheel cavity (4), and an air-liquid heat exchanger (5) that are disposed in the circulation air passage. The air exhaust apparatus (3) comprises an air inlet (30) and an air outlet (31). The air exhaust apparatus (3) sucks in air by means of the air inlet (30) and blows out the air by means of the air outlet (31). The color wheel cavity (4) is used to receive a color wheel, so that the air blown out by the air exhaust apparatus (3) cools down the color wheel. The air-liquid heat exchanger (5) performs a heat exchange between a liquid circulating therein and air in the circulation air passage. The invention can solve a problem of a low excitation efficiency of a wavelength conversion material resulting from a temperature rise of a color wheel and attachment of dust to the color wheel.
