Abstract
A heat exchanger 11 for use as a cross flow radiator for an engine cooling system has a heat exchanger matrix 12, header tanks 13, 14 and a side plate 16 arranged at the upper of a pair of opposite side edges 16, 17 of the matrix 12. The matrix 12 has tubes 18 which extend between tanks 13, 14 and cooling fins 19. A restrictor plate 21 arranged on side plate 16 restricts air flow past fin 19A. Restrictor plate 21 may have cut out gaps or castellations 22. This reduces heat transfer through the fins above the uppermost tube 18A allowing for a more even temperature distribution, which reduces stress from thermal expansion.
