Bamsaur, Racine, Wis, asslgnor to General Motors Corporation, Detroit, Mich, a

4 Claims. (Cl. 257-139) v In the drawing Figures 1 and 2 are elevations showing optional forms of tube assemblies, some of the radiating fins being omitted for clarity, and Figure 3 is a detail perspective view of the interfitting heat exchange parts.
The condenser assembly consists essentially of a long continuous tube which for-compactness may be bent upon itself either back and forth as illustrated in Figure l or spirally as in Figure 2. In either case a corrugated separator is interposed between the recurring lengths of tubing. The tube comprises a pair of complementary narrow strips l.-l arranged face to face, each with a pair of fiat and relatively wide side wings 2-2 bonded tothe corresponding wings of its neighboring strip together with a relatively narrow rib or semi-circular embossment 3 running medially of the strip and throughout its entire length for cooperation withthe aligned rib in the mating strip to form the enclosed tube space. The separator or spacer strip 4 is' of zigzag formation with its apices bearing against adjacent wings and having a central depression or seating formation 5 to bridge or receive therein the tube embossment 3. The resulting nested relation interlocks the parts together against displacement -and insures their mutual reinforcement.
In manufacture a ribbon of selected width is passed through a roll die machine to form the spacer strip 4 and another ribbon is passed through a suitable'die to press the embossment 3 in the strip I. The formed strips are cut to desired length and twoofthe strips I are brought togetherface to face with the ribs 3 projecting. away from one another. They are then bent either to the zigzag or "spiral shapes of Figures 1 and 2, respectively, with, the separator 4 -inter-. posed in proper position. In the case of Figure 1 an additional supporting and spacing frame 6 may be placed over the top andbottom of the.
assembly. The whole assembly is then dipped in solder for the capillary flow of the hot metal between the contacting surfaces for joining and sealing the-parts. Pipe sections I inserted and sealedin the opposite ends of the condenser tube will serve to connect the assembly in the sys circuit.
The resulting assembly possesses inherent strength and good heat dissipation characteristics. It will be noted that a considerable amount of fin surface ispresent in relation to the size of the tube space and further that the side wings 2-2 constitute heat radiating fins integral with the tube and these-are augmented by the large radiating surface afforded by the corrugated spacer 4 whose fins extend transversely of the plane of the wings 2. The exchange of heat is between the'fluid flowing through the tube space and that flowing through the assembly or between the tubes and over the fin surface.
I claim:
-l. In a heat exchanger, a pair of complemen-.
tary strips having aligned and relatively narrow embossments affording tube space and relatively wide side wings joined togethed to seal the space and afford axially extending heat radiating fins integral with the tube, and auxiliary heat radiating fins extending transversely of the plane of the first mentioned fins and including a corrugated strip having its apices secured in thermal contact to the wings on both sides of the narrow embossment with seating formations in interlocking relation to an adjacent tube embossment.
2. In a heat exchanger, a tube comprising a pair of complementary sheet metal ribbons each having medially thereof a tube forming rib and apair of oppositely disposed axially extending heat radiating fins 'joined throughout their surface area to the corresponding fins of-its complementary ribbon, and a series of transversely I projecting supplementary heat radiating fins bonded to the first mentioned fins.
3. In a heat exchanger, a corrugated separator strip having tube seats in the crests thereof, and
a tube fitting said seats, and having apair of oppositely disposed-axially extending heat radiating fins. bonded to said'crests on both sides of the tube seats.
4. In a heat exchanger, a pair of tube spacer strips of corrugated formation having tube seats in the crests thereof, a tube between" said spacer strips comprising a pair of complementary ribbons having aligned tube forming ribs medially thereon fitted to said seats and. each ribbon having a pair of oppositely disposed axially extending heat radiating joined on the inner faces to the mating fins of the complementary ribbon and joined .in heat transfer abutment on their outer faces to the crests of'the adjacent spacer strip on both sides ofthe tube seats. 7
