Abstract: As an ejector of the present disclosure and a cooling apparatus having the same include a suction guide unit at least partially having a curved surface so that the ejector guides a flow of a refrigerant, a structure is improved and thus a flow loss can be reduced. Also, through the improved structure, a mixture rate between a refrigerant passing through a nozzle unit and a refrigerant passing through a suction unit is improved, so that pressure rising efficiency can be increased to reduce a compressor load, and thus energy efficiency can be increased due to an increase in efficiency of the ejector.

Abstract: Disclosed herein is a refrigeration cycle includes a first refrigerant circuit configured to cause a refrigerant ejected from a compressor to flow through a condenser, an ejector, a first evaporator, and a second evaporator and flow back to the compressor; a second refrigerant circuit configured to cause the refrigerant to bypass the first evaporator in the first refrigerant circuit; and a third refrigerant circuit branching at a junction provided at a downstream end of the condenser from at least one of the first refrigerant circuit and the second refrigerant circuit, and configured to cause the refrigerant to flow through an expansion device and a third evaporator and flow to the ejector. By such configuration, a coefficient of performance (COP) of a refrigeration cycle may be improved and an ejector may be used to improve energy efficiency.
