Abstract: An apparatus and a method are provided for a modular intercooler block that may be fabricated by way of direct metal printing and assembled to form larger intercoolers. The modular intercooler block comprises cooling fins that are spaced between first and second core headers to allow passage of an airstream. Countersunk holes are arranged on the first and second core headers and configured to receive grommets when the first or second core header is fastened to another core header comprising similarly arranged countersunk holes. A core tube extends along an undulating path from each countersunk hole in the first core header, through the multiplicity of cooling fins, to a similar countersunk hole in the second core header. The core tubes may include thin copper walls and spiraled inner passages to enhance heat transfer to the airstream passing through the multiplicity of cooling fins.

Abstract: Heat exchangers and methods for assembling a heat exchanger are described, such as for example a round tube heat exchanger, which may be a fin and tube heat exchanger, and which may be used for example in a heating, ventilation, and air conditioning system (HVAC) system and/or unit thereof. The heat exchanger includes aluminum tubes mechanically rolled into an aluminum tube support and the tubes are fluidically sealed with the tube support. The aluminum tube support including the aluminum tubes rolled therein is assembled to a fluid manifold configured to allow fluid flow through the heat exchanger and into and/or out of the heat exchanger.

Abstract: A heat exchanger includes a plurality of plate-shaped fins disposed at intervals, and a plurality of heat transfer tubes disposed to be inserted into through holes of the fins in a direction perpendicular to the fins. In each of the fins, a starting hole is formed between adjacent through holes, and the starting hole serves as a start point of bending of the fins and has a vertex portion at a bending portion of each fin which is close to an edge thereof. In each of the fins, a cut is made to connect the other edge of the fin and a side of the starting hole which is located opposite to the vertex portion of the starting hole. The above each fin is bent at the vertex portion of the starting hole, by opening the cut from the starting hole.
