Abstract
Abstract A condenser (10) for use in a car cooling system, comprising a pair of parallel headers (13, 14), a plurality of tubular elements (11) whose opposite ends are connected to the headers (13, 14) and fins (12) provided in the air paths between adjacent tubular elements (11), each of the headers (13, 14) being made of a cylindrical pipe of aluminum and each of the tubular elements (11) being made of a flattened hollow tube of extruded aluminum, the opposite ends of the tubular elements (11) being inserted into slits (15) provided in the headers (13, 14) and soldered therein so as to be liquid-tight.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
A condensing apparatus 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; and wherein the opposite ends of the tubular elements are inserted in slits produced to the headers, and liquid-tightly secured therein; wherein at least one of the headers is internally divided by a partition into at least two groups of coolant passageways, thereby enabling the flow of coolant to make at least one U-turn in the header; and wherein the partition is inserted in the header through a slit produced in the header and secured therein.
