PURPOSE: To make it possible to distribute refrigerant at an equal flow rate and enhance a flow-divided state even when a flow divider is installed on a slant by providing a cone-shaped flow dividing body in the flow divider which connects the flow passage of a heat exchanger having a plurality of refrigerant flow passages.

CONSTITUTION: In a flow divider 1 which is used for an air conditioner or the like and designed to divide the flow of refrigerant in a two phase (vapor and liquid) state to be introduced into a heat exchanger, a cone-shaped flow dividing body 2 is provided movably in the flow divider 1. A flow-in pipe 3 is mounted to one end of the flow divider 1 whereas two flow-out pipes 4 are mounted to the other end. When the flow divider 1 is installed on a slant, a liquid-phase portion of the refrigerant which has flowed in the flow divider 1, is apt to flow to the D side of the flow-out pipes 4 so that the flow rate of refrigerant on the D side may be inclined to increase. In this case, the cone-shaped flow dividing body 2 is housed therein while the inlet of the flow-out pipe 4 on the D side is reduced in size. This construction makes it possible to inhibit the refrigerant from flowing in the flow-out pipe on the D side and provide a satisfactory flow divided state, allowing the refrigerant to flow in the pipe on the C side.
