  • the present invention relates generally to a heat exchanger and more particularly a multi-fluid heat exchanger, employing an improved baffle.
  • baffles Due to relatively recent advancements in the field, including, in particular, the development of combination heat exchanger assemblies or 'combo coolers', there is also a need to develop systems of more than one baffle to insure that multiple fluids be maintained basically separated from one another. As stated above, particularly where a multi-fluid heat exchanger is to be employed, it is attractive to be able to maintain each of the different fluids of the exchanger separated from each other.
  • baffles is one possible approach.
  • baffle designs have often resulted in space problems, and the like, contributing to the loss of function or efficiency of one or more of the heat exchanger tubes.
  • certain heat exchanger assemblies may have space requirements that extend to at least one core tube end in the tank.
  • baffle perimeter walls or "flanges” that increase bonding against the tank perimeter and take up additional space that eventually restricts performance due to the fact that tube center to center spaces can not be optimized.
  • the solution has often been to insert, during assembly, at least two separate pieces, each providing a baffle, to form a so called double baffle. Often a first and a second baffle are assembled back to back.
  • a double baffle is in actuality, therefore, two baffles, as the two separate baffles have a space between the pieces to ensure that one fluid in the separate fluid systems remains separated from the other.

  • a baffle or, in particular, a double (or multiple) baffle system, can be used that provides the separation of fluids necessary for adequate functioning of heat exchange for each fluid.
  • a one-piece double baffle may be used to ensure that the separate fluids of the multi-fluid systems remain essentially separated from one another.
