Benefits of technology

This patent describes a vehicle condenser that reduces heat-related issues and improves cooling efficiency. It separates refrigerant into gas and liquid and condenses them using coolant, which is then overcooled using another refrigerant. This reduces the need for additional components, simplifies connections, and lowers weight and cost. The condenser also includes a heat-isolating portion that allows for easy installation of the nitrogen. Additionally, a fixing cap prevents escape of the desiccant and leakage of the refrigerant.

Problems solved by technology

Therefore, the air-cooled condenser may be hard to be installed in a small engine compartment.
Therefore, condensing efficiency may be deteriorated due to small sub-cool effect, and accordingly cooling efficiency may also be deteriorated.
Therefore, cost and weight may increase and connections between the receiver-drier and the condenser may be complex.

Abstract

A condenser for a vehicle is used in an air conditioning having an expansion valve, an evaporator, and a compressor, is provided between the compressor and the expansion valve, and circulates coolant supplied from a radiator so as to condense refrigerant supplied from the compressor through heat-exchange with the coolant and the refrigerant.The condenser may include a main heat-radiating portion connected to the radiator to circulate coolant, and adapted to circulate refrigerant from the compressor to condense the refrigerant through heat-exchange with the coolant, a receiver-drier portion integrally formed with the main heat-radiating portion to receive the condensed refrigerant perform gas-liquid separation and moisture removal of the refrigerant, and an overcooling heat-radiating portion circulating low temperature and low pressure gas refrigerant supplied from the evaporator, and overcooling the refrigerant supplied from the receiver-drier portion through heat-exchange with the low temperature and low pressure gas refrigerant.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority of Korean Patent Application Number 10-2011-0131299 filed Dec. 8, 2011, the entire contents of which application is incorporated herein for all purposes by this reference.BACKGROUND OF INVENTION[0002]1. Field of Invention[0003]The present invention relates to a condenser for a vehicle. More particularly, the present invention relates to a condenser for a vehicle that is stacked-plate type in which a receiver-drier is integrally formed and that is water-cooled type in which a refrigerant is condensed by using a coolant.[0004]2. Description of Related Art[0005]Generally, an air conditioning for a vehicle maintains suitable cabin temperature regardless of ambient temperature and realizes comfortable indoor environment.[0006]Such an air conditioning includes a compressor compressing a refrigerant, a condenser condensing and liquefying the refrigerant compressed by the compressor, an expansion valve quick...
