Patent ID: 8434324

Claim:
An evaporator unit comprising: an ejector configured to suck refrigerant through a refrigerant suction port by a high-speed refrigerant flow jetted from a nozzle portion, to mix the refrigerant jetted from the nozzle portion and the refrigerant sucked through the refrigerant suction port, and to discharge the refrigerant; a first evaporator connected to the outlet side of the ejector and evaporating the refrigerant discharged from the ejector; a second evaporator connected to the refrigerant suction port and evaporating the refrigerant to be drawn into the ejector; a refrigerant dividing portion connected to the inlet side of the nozzle portion and the inlet side of the second evaporator and adjusting the flow amount of refrigerant flowing in and divided to the nozzle portion and the second evaporator; and a joint in which a refrigerant inlet and a refrigerant outlet are formed and which causes the refrigerant flowing in through the refrigerant inlet to flow out to the refrigerant dividing portion and causes the refrigerant flowing out of the first evaporator to flow out to the refrigerant outlet, wherein the ejector, the first evaporator, the second evaporator, the refrigerant dividing portion, and the joint are integrally assembled to configure an integrated unit, the joint is provided with a gas-liquid separation portion that causes the refrigerant flowing therein to swirl and to separate the refrigerant into gas and liquid, and the ejector, the refrigerant dividing portion and the joint are arranged in a longitudinal direction of the ejector.
