AI Technical Summary
Technical Problem
Existing light source devices and projectors lack effective cooling mechanisms for both the phosphor wheel and the motor, leading to inefficiencies in heat management and potential size constraints.
Method used
A light source device with a heat transfer member made of metal, connected to the housing, that dissipates heat from both the phosphor wheel and the motor through a bearing portion and side wall, utilizing a heat dissipation member with higher thermal conductivity than air to facilitate efficient heat transfer.
Benefits of technology
The solution effectively cools both the phosphor wheel and the motor, allowing for a smaller device size and improved brightness and lifespan of the projector, while enhancing heat dissipation.

Abstract
The present invention provides a light source device and a projector capable of improving heat dissipation. [Solution] The wavelength conversion device comprises a light source, a rotating plate 502 that acts on the light emitted from the light source and a motor 505 that rotates the rotating plate 502, a housing housing that houses the light source and the wavelength conversion device, and a heat transfer member 65 fixed to the housing housing and having a metal side wall portion 65a. The motor 505 has a rotor portion 801 connected to the rotating plate 502 and rotating the rotating plate 502, a stator portion 802 fixed to the heat transfer member 65 and rotating the rotor portion 801, and a bearing portion 820 that rotatably supports the rotating shaft portion of the rotor portion 801. The bearing portion 820 and the inner surface of the side wall portion 65a are connected in a way that allows heat transfer.
