Abstract
A condenser for a vehicle includes an integrally formed receiver-drier and a plurality of stacked plates. The condenser may be used in an air conditioning having an expansion valve expanding liquid refrigerant, an evaporator evaporating the refrigerant expanded at the expansion valve through heat-exchange with air, and a compressor receiving from the evaporator and compressing gaseous refrigerant, may be provided between the compressor and the expansion valve, and may circulate coolant supplied from a radiator so as to condense the refrigerant supplied from the compressor through heat-exchange with the coolant and the refrigerant.
Claims9
A condenser for a vehicle which is used in an air conditioning system having an expansion valve expanding liquid refrigerant, an evaporator evaporating the liquid refrigerant expanded at the expansion valve through heat-exchange with air to change the liquid refrigerant into gaseous refrigerant, and a compressor receiving from the evaporator and compressing the gaseous refrigerant, wherein the condenser is provided between the compressor and the expansion valve, and wherein the condenser circulates coolant supplied from a radiator to condense the compressed refrigerant supplied from the compressor through heat-exchange with the coolant, the condenser comprising:
- a first heat-radiating portion formed by stacking a plurality of first plates, connected to the radiator to circulate the coolant, and circulating the refrigerant supplied from the compressor to condense the compressed refrigerant through heat-exchange with the coolant, wherein each of the first plates have an opening;
- a second heat-radiating portion integrally formed at a lower portion of the first heat-radiating portion formed by stacking a plurality of second plates, and circulating the gaseous refrigerant of low temperature/pressure supplied from the evaporator, wherein each of the second plates have an opening;
- and
- a receiver-drier portion, wherein the openings of the first and second plates are aligned to form a space containing the receiver-drier portion,
- wherein the receiver-drier portion receives the condensed refrigerant from the first heat-radiating portion, performing gas-liquid separation and moisture removal of the compressed refrigerant,
- wherein the receiver-drier portion sends the refrigerant in which the gas-liquid separation and the moisture removal is performed to the second heat-radiating portion, and
- wherein the second heat-radiating portion overcools the refrigerant passing through and supplied from the receiver-drier portion through heat exchange with the gaseous refrigerant of low temperature/pressure supplied from the evaporator.
