Condenser and radiator of air conditioning refrigeration system

Abstract

The present invention provides a radiator or condenser used in an air conditioning system. The radiator comprises at least one radiator unit, wherein the radiator unit includes at least two lobes, two of the at least two lobes facing to and hermetically attaching to each other, and at least one through hole disposed in the middle part of the two lobes along the height thereof. The present invention also provides a radiator unit or condenser unit used to form the radiator or condenser.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority benefit of China application No. 200610122167.0 filed on Sep. 15, 2006, the contents of which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a condenser and a radiator used in an air conditioning refrigeration system, and more particularly, to a condenser unit and a radiator unit used to form the condenser and the radiator.BACKGROUND OF THE INVENTION[0003]It is known that the refrigeration principle of a vehicle is the same as that of a home air conditioner, which makes use of instant rapid volume expansion of refrigerating medium, such as R12 or R134a in the manner of compression releasing, to absorb a large mount of heat from ambience. Besides a compression pump, a condenser shown in FIG. 1A and a radiator shown in FIG. 1B are both important parts of an air-conditioning system. Although they are differently named, their structures are simil...

AI Technical Summary

Benefits of technology

[0015]Since the radiator unit or condenser unit used to for the radiator or condenser of air conditioning system could be formed integrally, no soldering process or bending process is needed. Furthermore, since the through holes in the radiator unit or condenser unit could be formed integrally, the thermal impedance will be very low, and well heat transferring will be achieved. In addition, since the through holes have corrugated walls, the area of heat exchanging is greatly increased, then the efficiency of heat exchanging and radiating will be highly improved. Therefore, the radiator or condenser of the p

Problems solved by technology

In such kinds of heat exchange devices, there are following shortages.

In addition, each welded contact point is subject to breakage due to the long period of heat/cold temperature exchanging, so that it is prone to forming gap between the copper tubes or aluminum ribbon-shaped strips and the aluminum sheet assembly.

As the walls are thin, it could not bear high pressure.

Therefore, the curve tubes are subject to perforation or breakage after high pressure refrigerating medi
