Abstract
The invention relates to a heat pipe cooling system for a liquid crystal on silicon ( LCOS) projector. The system comprises an optical main body and a sealing member, wherein the sealing member is used for sealing the optical main body and conducting and dissipating the heat generated by the optical main body; the sealing member comprises a shell and a heat dissipating device; the heat dissipating device and the optical main body are tightly jointed; and the heat dissipating device comprises a heat absorber, a heat dissipating cushion and a heat pipe connected with the heat absorber and the heat dissipating cushion. The heat pipe cooling system for the LCOS projector conducts the heat through the heat pipe, thereby ensuring the normal operation of the LCOS projector and effectively improving the stability of the LCOS projector. In addition, the optical main body is accommodated and completely sealed by the sealing member 200 so that external dust or dirt can not enter the inside of the sealed LCOS projector, thereby achieving good dust-proof effect and ensuring the imaging quality of the optical main body.
