  • Publication number: 20150053385
    Abstract: The heat exchanger flow balancing system serves to substantially equalize fluid flow through essentially identical diameter heat exchanger tubes in a heat exchanger having a single inlet plenum, a single outlet plenum, and a series of equal diameter heat exchanger tubes extending therebetween. In one embodiment, a series of different diameter orifices are provided at the inlet end of each of the tubes, with those tubes farther from the single larger diameter inlet pipe to the plenum generally having smaller orifices. In another embodiment, each of the tubes is provided with a conical nozzle at its inlet end, with those tubes farther from the single inlet pipe to the plenum generally having smaller diameter nozzles. The effect is to substantially equalize fluid flow through all of the heat exchanger tubes, thus increasing the efficiency of the heat exchanger.
