PURPOSE: An apparatus for distributing amount of flow is to control flow of fluid according to heat flux which enters an optical part in an LCD(liquid crystal display) projector. CONSTITUTION: The apparatus comprises a flow distributor(18) and a cross flow fan(20). The flow distributor has an interception wall(18a) to divide a vent(24a,24b,24c). The interception wall is rounded with a predetermined curvature to provide the flow to a mixed stock. The interception wall is rounded to the same direction. The vents are formed by the interception wall. The cross flow fan provides the flow to a suction port(26a,26b,26c) of the flow distributor. The cross flow fan comprises a rounding fan and a sidewall. By the sidewall, an axial leakage in the flow is prevented. The rounding fan is supported by the sidewall. The rounding fan is rounded from its center to periphery with the predetermined curvature.
