Condenser for use in a car cooling system

A condenser adapted for use in the car cooling system, the condenser comprising:

• a pair of headers provided in parallel with each other;
• a plurality of tubular elements whose opposite ends are connected to the headers;
• fins provided in air paths present between one tube and the next;
• wherein each header is made of an aluminum pipe having a circular cross-section;
• wherein each of the tubular elements is made of a flat hollow aluminum tube made by extrusion;
• and
• wherein the opposite ends of the tubular elements are inserted in slits produced in the headers, and liquid-tightly soldered therein;
• wherein the soldering substance is previously coated in the headers or the tubular elements or both;
• wherein at least one of the headers is internally divided by a partition into at least two groups of coolant passageways, wherein one group is located toward the inlet whereas the other is located toward the outlet, thereby enabling the flow of coolant to make at least one U-turn in the header;
• wherein the opposite ends of the partition are inserted in a semi-circular slit produced in the header and soldered therein;
• and
• wherein the partition is disc-shaped, having a larger circular portion and a smaller circular portion, the partition is inserted in the header through the slit with the larger circular portion being secured in the slit and with the smaller circular portion being kept in contact with the inside wall surface of the header.
