Abstract:
1. A heat exchanger comprising: a manifold for receiving a fluid to be cooled and for returning the fluid to be cooled to a system to be cooled; said manifold communicating with passages in a plurality of mini-channel tubes, and a manifold at an opposed end of said mini-channel tubes, such that fluid can enter said manifold through an inlet, pass axially through a first pass of said mini-channel tubes which is composed of two tubes in parallel per layer, reach said manifold, and be returned axially through a second pass of said mini-channel tubes to said manifold, and to communicate with an outlet; and said plurality of mini-channel tubes, including an axial length defined between said manifold and said manifold, and said mini-channel tubes, including a plurality of generally rectangular flow passages, said generally rectangular flow passages being aligned adjacent to each other to define a lateral dimension and a first lateral width of said generally rectangular passages being defined, with a ratio of said axial length to said first lateral width being between 201.3 and 215.3.
