PURPOSE: To enable a uniform divided flow of refrigerant to be attained by a method wherein a refrigerant flow divider is comprised of a cylindrical container composed of a pair of container segments, a flow-in pipe having a nozzle part formed at a flow-out part connected to an insertion hole for the flow-in pipe and a plurality of flow-out pipes inserted into the insertion holes for the flow-out pipes, connected while their insertion ends being contacted with a lower surface of the cylindrical container and having recesses at a central part of the cylindrical container at the insertion end.

CONSTITUTION: A cylindrical container 2 is formed such that a container 2a having flow-out pipe insertion holes 7 at its upper surface and a container 2b having a flow-in pipe insertion hole 6 are overlapped to each other and welded at 2c. A recess 9 is formed at a central part of the cylindrical container 2 at an end part of a flow-out pipe 14 to act as a refrigerant passage. In the refrigerant flow divider 1, a gas-liquid mixing of the refrigerant is promoted by a nozzle 8 of the flow-in pipe 3, resulting in that a separation of gas and liquid is restricted. In addition, the flow-out pipe 4 is inserted and connected until it strikes against a lower surface of the cylindrical container 2, thereby it is not necessary to adjust margin in insertion of the flow-out pie 4 and thus its connection can easily be carried out. With such an arrangement, a uniform divided flow can be attained and a dividing flow property can be stabilized.
