Abstract

A condenser apparatus includes a pair of headers provided in parallel with each other; a plurality of tubular elements whose opposite ends are connected to the headers; and fins provided in the air paths between one tube and the next. Each of the headers is made of a cylindrical pipe of aluminum. At least one of the headers is internally divided by a partition into at least two groups of coolant passageways, thus enabling the flow of coolant to make at least one U-turn in the header. The partition extends into the header through a slit in the header. Each of the tubular elements is made of a flat hollow tube of aluminum. The opposite ends of the tubular elements are inserted into slits produced in the headers so that they are liquid-tightly secured.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. 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 headers; and   wherein the partition is inserted in the header through a slit produced in the header and secured therein.Iadd., the portion of the partition disposed in the header being without any perforations.Iaddend..
