Definitions

  • a further object of the invention is an extruded tube construction that may be manufactured simply and yet yield enhanced bonding performance over conventional extruded tube heat exchange systems.
  • the present invention is directed to a fin-tube block type heat exchanger in which extruded tubes are alternatingly arranged with corrugated fins, the fins being shorter in overall length than the tubes and having elongated bars at their ends serving as spacer bars between the tubes.
  • the spacer bars have opposed side walls that, adjacent their outer walls, abut the side walls of the tubes.
  • the side walls of the spacer bars are substantially parallel to each other and adjacent their inner walls abut the side walls of the tubes.
  • the core 12 includes a plurality of parallel tubes 16 defining a first set of parallel flow passages 18 extending between the tanks 14a and 14b, and corrugated fins 20 alternatingly arranged with the tubes 16 and defining a second set of parallel flow passages 22 oriented generally perpendicularly relative to the first set of flow passages.
  • Each tube 16 preferably is extruded, is made of aluminum, and includes opposed side walls 16a, opposed end walls 16b, and pillars 16c extending between the side walls 16a to define the first set of flow paths 18.
  • the side walls 40a are attached by a strip that covers the surface to be bonded, a taper at the bar-to-panel joint is not necessary.
  • the outwardly-facing side walls 40a can be attached to the facing surfaces of the side panels 42 by a filler wire.
  • the inner walls 40d taper from both the outwardly-facing side walls 40a and the inwardly-facing side walls 40b so as to form a peak 29 that contacts the facing ends of the fins 20.
  • Figure 9 shows a spacer bar 424 in which two recesses 426 are provided in each of the side walls 424a, and in which the side walls 424a are substantially parallel to each other so as to abut against the side walls of the tubes 16, except for that portion immediately adjacent the inner wall 424c, where a space 430 is maintained between the side walls 424a and the side walls of the tubes 16.
  • the filler 428 is in the form of a wire of circular cross-section, and the recesses 426 are substantially complementary in shape to the filler 428, so as to provide very small capillary regions 460 at the interfacial region of the recesses 426 with the side walls of the tubes 16.
  • Figure 10 shows a spacer bar 524 with an alternative contour of the side walls 524a adjacent.
