Patent JP-H03177761-A (JP)
Title: Heat exchanger
Inventor: ANDO TOMOAKI
IPC: F25B41/00
Filed: 1989-12-06
Abstract: PURPOSE:To supply a regrigerant in the form of a gas-liquid two-phase flow, which is stable and has a high ratio of a liquid refrigerant to a gas refrigerant, to each heat transfer tube by providing a means for generating a spinning stream of the gas-liquid two-phase flow having a high ratio of the liquid refrigerant in a flow diverter and arranging the inlet ends of a plurality of flow passages in the spinning stream. CONSTITUTION:A refrigerant 17 converted into a gas-liquid two-phase flow by pressure reduction flows from an inlet tube 10 into a flow diverter 11. In this case, a spinning stream is generated along a spiral groove 16 formed on the side wall surface of a chamber 12. Since the specific weight between a gas refrigerant and a liquid refrigerant is different as much as several tens to 100 times, the liquid refrigerant having the heavy specific weight flows in the vicinity of the wall surface due to centrifugal force, while the gas refrigerant flows through the center of a flow passage. Therefore, the gas refrigerant flows into outlet tubes 13 provided at the central part of the flow passage, while the liquid refrigerant flows into outlet tubes 14 provided at the peripheral part of the flow passage. Since the outlet tubes 13 are connected to the outlet tubes 14, the gas refrigerant and the liquid refrigerant are mixed with each other to flow into outlet tubes 15. As a result, a flow ratio of the gas and liquid refrigerant in each outlet tube 15 becomes relatively uniform; therefore, when it flows into a heat exchanger, a maximum heat exchanging ability that is always stabilized can be obtained without causing an effective heat transfer area to be reduced due to ununiformity of the refrigerant flow rate between heat transfer tubes.
