FLOW DIVIDER, EXPANSION VALVE WITH THE FLOW DIVIDER, AND REFRIGERATION DEVICE WITH THE EXPANSION VALVE

摘要

A flow divider (7) comprises: a flow divider body section (70) having therein a flow divider chamber (70A) through which a refrigerant flows; a first piping-mounting hole (71a) provided to the flow divider body section (70); and a second piping-mounting hole (72c) to which flow-dividing pipes (CP3) are connected, the flow-dividing pipes (CP3) dividing the refrigerant which flows into the flow divider chamber (70A) through the first piping-mounting hole (71a) and causing the divided flows to flow out of the flow-dividing pipes. The flow divider chamber (70A) comprises: a swirl flow-forming chamber (70B) in which the refrigerant which flows therein from the first piping-mounting hole (71a) forms a swirl flow; a speed-increasing chamber (70C) for increasing the swirl speed of the refrigerant which flows out of the swirl flow-forming chamber (70B); and a spray chamber (70D) for converting to static pressure a portion of the dynamic pressure of the refrigerant which flows out of the speed-increasing chamber (70C). The spray chamber (70D) is connected to the second piping-mounting hole (72c).
