COLOR WHEEL MODULE

WIPO Patent Application WO/2019/075993

A1

A color wheel module (100) comprises a housing (1), a separator (2) and a color wheel (3). The housing (1) is provided with an accommodation space (10), and the accommodation space (10) is divided into a color wheel mounting space (101), a connection space (102) and a cooling space (103). The separator (2) is provided in the connection space (102), and the connection space (102) is divided into a first airflow channel (4) and a second airflow channel (5). The first airflow channel (4) is in communication with the color wheel mounting space (101) and the cooling space (103) respectively, the second airflow channel (5) is in communication with the color wheel mounting space (101) and the cooling space (103), and the color wheel mounting space (101), the first airflow channel (4), the cooling space (103) and the second air flow channel (5) are connected in a closed manner to form an airflow circuit. The color wheel (3) is mounted in the color wheel mounting space (101). The color wheel module (100) achieves, in a state where the housing (1) is completely closed, heat exchange between the color wheel (3) and the outside air, and effectively improves the heat dissipation effect of the color wheel (3).
