Methods and apparatus for heating or cooling heat exchanger manifolds and side bars during transient operation to control structural deformation and resultant stresses. Special internal passages are provided in the manifolds and side bars of a plate-and-fin heat exchanger through which heated air is diverted during operation of the heat exchanger, thus serving to stabilize the temperature of selected portions of the heat exchanger in line with operating temperatures of related heat exchanger elements. This serves to minimize thermal gradients and resultant thermal stresses in the overall heat exchanger structure.
