Claim 3:
4. The new heat dissipation structure for sealed optical machines of claim 1, wherein the second heat dissipation fan (11) is arranged horizontally to the internal radiator (16) and is located on the upper part of the reflector (2); the airflow blown by the second heat dissipation fan (11) in the sealed space is guided by the housing and then flows through the liquid crystal screen (5) with a higher temperature; after taking away the heat from the liquid crystal screen, the airflow will exchange heat with the internal radiator (16) to cool down, and then flow back to the second heat dissipation fan (11) after passing through the reflector (2), so as to form a closed “O”-shaped heat dissipation air path.
