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.

Description

technical field [0001] The present disclosure relates to an ejector and a cooling apparatus having the same, and more particularly, to an ejector having an improved structure to increase efficiency and a cooling apparatus having the same. Background technique [0002] Typically, a refrigeration unit consists of a compressor, a condenser, an evaporator, and an expansion device. The compressor compresses high-temperature and high-pressure refrigerant, and the condenser condenses the refrigerant discharged from the compressor and turns the refrigerant into liquid refrigerant. The expansion device reduces the temperature and pressure of the refrigerant discharged from the condenser to the state required by the evaporator through the throttling process. When the refrigerant evaporates by absorbing heat from the ambient air while passing through the evaporator, the refrigerant becomes a saturated air state at the outlet of the evaporator, and then when the refrigerant is reintrod...
