Claims11
A braze furnace cooling system for brazing heat exchangers, the heat exchangers having a plurality of fins and a plurality of return bends, the system comprising:
- a brazing heat source;
- a conveyor configured to move heat exchangers in a direction of travel such that the return bends are proximate to the brazing heat source for a period of time;
- one or more fluid nozzles configured to direct a sheet of pressurized fluid along the plurality of fins.
A method of cooling a heat changer, comprising:
- moving an unbrazed heat exchanger through a brazing furnace;
- brazing a joint of the heat exchanger in the brazing furnace;
- moving the brazed heat exchanger past one or more fluid nozzles;
- and
- directing a sheet of pressurized fluid along the plurality of fins using the one or more fluid nozzles.
