A countercurrent heat exchanger that compensates automatically for maldistribution of flow in parallel channels
Abstract
A technique is proposed for an effective reduction of the effect of manufacturing tolerances, manifolding effect, and other factors on flow imbalance. Basically, the design approach creates a negative feedback system in a countercurrent heat exchanger that reduces the effect of the unbalancing factors by a decade or more. The technique is shown to be applicable to any form of countercurrent heat exchanger and can be utilized with little or no added complexity of design. Test result point to an improved performance with the same basic design of countercurrent heat exchanger.
