Definitions

  • This invention relates to heat exchangers and more particularly to a heat exchanger hermetically sealing and enclosing equipment to be cooled.
  • the device is particularly adapted for cooling electronic equipment which must operate in rarefied atmospheres. It is, therefore, desirable and often necessary that the pressure of air in the equipment space be maintained at a higher level than that of the ambient air.
  • It is another object of the invention to provide means for cooling a sealed first container comprising an outer casing which houses, but is spaced from the first container to provide pasasgeways therebetween, heat transfer elements in the passageways and openings in the second container for the movement of cooling fluid into and out of the passageways.
  • an inner tapered container In is another object of the invention to provide an inner tapered container, an intermediate tapered container housing the inner container, an outer tapered container housing the intermediate container, heat transfer fins between the containers whereby the inner casing may be forced into the intermediate container and the intermediate container may be forced into the outer container to force the heat transfer fins into contact with the containers.
  • FIG. 1 is a side elevational view of the changer
  • FIG. 2 is a top view of the heat exchanger
  • FIG. 3 is a perspective view in cross-section on line 3-3 of FIG. 1 with some parts in exploded position to more clearly show the interior construction
  • FIG. 4 is a perspective view on an enlarged scale showheat exing the fin and the upper portion of the outer casing.
  • the heat exchanger has an inner container 10, an intermediate container 12, and an outer container 14.
  • Mounting posts 16 extend through and are brazed to the bottom ends of containers 10, 12, and 14.
  • Equipment to be cooled which is in the inner container is supported on the inner ends of posts 16.
  • the outer ends of the posts 16 are adapted to be secured to a support (not shown).
  • the outer container 14 has a hole 18 adapted to be connected to the suction of a fan (not shown). Air or other cooling fluid is drawn in through holes 20 in the outer container 14 and flows in the passageways between the sides of containers 12 and 14.
  • Corrugated heat transfer fin material 22 extends between and is brazed to the sides of the containers 12 and 14.
  • corrugated distributor heat transfer fins 24 and 26 are corrugated distributor heat transfer fins 24 and 26. These fins provide substantially uniform flow of fluid in the passageways between the containers 12 and 14 in addition to transferring heat from the end wall of container 12 to the fluid flowing in the passageways.
  • the end wall of the container 10 has a hole 28 which is adapted to be connected to the discharge of a fan which is part of the equipment (not shown) mounted in the container 10.
  • Corrugated distributor heat transfer fins 30 are mounted in the space between the end wall of container 1t) and the end wall of container 12. Pins 30 are arranged in the same manner as fins 24 and 26.
  • Heat transfer fins 32 are mounted in the spaces between the side walls of the containers 10 and 12. Holes 34 in the inner container 10 provide for the flow of air into the container 10 from the passageways between the containers 10 and 12. v
  • the distributor heat transfer fins 30 distribute the air or gas flowing from the hole 28 substantially uniformly to the space between the four side walls of the containers 10 and 12.
  • the distributor fins 24 and 26 provide flow conditions by which .uniform flow is obtained in the space between the four side walls of the con.-
  • the container 12 has an outwardly extending flange 36 which is brazed or welded to a clamping ring 38.
  • the top edge of the container 10 is brazed or welded to the clamping ring 38, and the top edge of the container 14 is brazed or welded to the lower surface of the flange 36.
  • O-ring sealing member 40 of resilient material such as neoprene is mounted in a groove in the top of the clamping ring 38 and provides a seal between the clamping ring 38 and the cover 42.
  • Bolts 44 extend through the cover 42 into threaded engagement with the clamping ring 38 to hold the cover 42 against the clamping ring 38 with the O-ring 40 in compressed condition to effect a seal.
  • the parts may be assembled by first placing the container 14 and the posts 16 in the fixture. Rings of brazing material (not shown) are placed over the posts 16 so that the rings rest upon the inside surface of the bottom of container 14. Distributor heat transfer fins 24 and 26 are now placed on the bottom of the outer container 14.
  • the intermediate container 12 with the fins 22 wrapped around its sides is now inserted in the outer container 14.
  • the distributor heat transfer fins 30 are then placed on the bottom of the intermediate container 12.
  • Rings of brazing material (not shown) are placed on the posts 16 so that the rings rest upon the inside surface of the bottom of container 12.
  • the inner container 10 with the heat transfer fins 32 wrapped around its sides is now inserted in the intermediate container 12. Rings of brazing material (not shown) are placed on the posts 16 so that the rings rest upon the inside surface of the bottom of container 10.
  • the tapered containers 1t 12, and 14 and the heat transfer fins 22 and 32 are sized so that pressure contact between these parts is established before the parts are in 10, 12, and 14 are tapered as indicated by numeral 46 in FIG. 1. Therefore, as the containers are forced into their final relative positions, the heat transfer fins 22 and Patented June 2., 1964 32 are compressed to insure that good brazing contact is obtained. It-should also be understoodthat container 12 is forced into container 14 until fins 24 and 26 are compressed for contact with the bottoms of containers 12 and 14, and in like manner container 10 is forced into container 12 until fins 30 are compressed for contact with the bottoms of containers l and 12.
  • the fixture holds the containers 1t 12, and 14 in such positions that the upper edge of container 19 is in line with the upper surface of flange 36 of container 12 and the upper edge of container'14 is in contact with the lower surface of flange 36.
  • the fins 22, 24, 26, 30, and 32 have on each face a thin layer of metal which has a lower melting tempera ture than that of the base metal of the fins.
  • the brazing rings also have a lower melting temperature than the other parts.
  • the assembly may be brazed in any suitable manner.
  • the assembly may be brazed by immersing in a salt bath to raise the temperature to the point at which the brazing rings and the brazing alloy on the surfaces of the fins melts and integrally joins the parts.
  • the clamping ring 38 may then be hand brazed or welded to the containers 10, 12, and 14.
  • the heat exchanger has been shown as substantially rectangular in cross-section, because this shape permits stacking several heat exchangers in a minimum space, the heat exchanger can be circular or substantially circular in cross section, if desired. 7
