Abstract
Methods for manufacturing brazed aluminum heat exchangers involved in boiling and condensing, including a high performance nucleate boiling surface bonded with the walls of fin-less boiling passages. One method includes providing a first heat exchanger core subassembly including a first joinable end, at least one cooling and one boiling passage, and a first partial finless passage arranged at the joinable end. A second heat exchanger core subassembly is provided similar to the first including a second joinable end. The first and second heat exchanger core subassemblies are brazed. The first joinable end is affixed, preferably by welding, to the second joinable end and the first partial finless passage is affixed to a second partial finless passage to form a coupled finless passage, and thereby a heat exchanger core.
