Abstract:
1. A condenser for a vehicle which is used in an air conditioner including an expansion valve, an evaporator, and a compressor, wherein the condenser is provided between the compressor and the expansion valve, and circulates coolant supplied from a radiator to condense refrigerant supplied from the compressor through heat-exchange with the coolant and the refrigerant, the condenser comprising: a first heat-radiating portion formed with a stacked plurality of plates, connected to the radiator to circulate the coolant, and adapted to circulate the refrigerant supplied from the compressor to condense the refrigerant through heat-exchange with the coolant and the refrigerant; a second heat-radiating portion integrally formed at a lower portion of the first heat-radiating portion and fluid-connecting the radiator and the first heat radiating portion to circulate the coolant; a receiver-drier portion formed with a stacked plurality of plates, disposed apart from and in parallel with the first and second heat-radiating portions, and connected respectively to the first and second heat-radiating portions to perform gas-liquid separation and moisture removal of the condensed refrigerant supplied from the first heat-radiating portion and to supply the refrigerant to the second heat-radiating portion; a lower cover simultaneously covering a lower portion of the second heat-radiating portion and a lower portion of the receiver-drier portion and having a connecting passage formed therein, the connecting passage being adapted to flow the refrigerant from the receiver-drier portion into the second heat-radiating portion, wherein the receiver-drier portion is provided with a space formed therein and a desiccant is inserted in the space, and wherein the connecting passage is formed in the lower cover between the second heat-radiating portion and the receiver-drier portion, an end of the connecting passage is connected to a first connecting hole formed at a lower portion of an end portion of the second heat-radiating portion, and another end of the connecting passage is connected to the receiver-drier portion, and a fixing plate mounted at the lower cover, wherein the connecting passage is formed between the fixing plate and the lower cover to fluid-communicate the space with the first connecting hole and wherein the fixing plate prevents leakage of the refrigerant to an exterior of the receiver-drier portion and prevents the desiccant inserted in the space from escaping.
