  • Heat exchanging device with heat exchanging plates
    Patent number: 4549603
    Abstract: A convection flow heat exchanger comprises peripherally flanged upper and lower manifolds 14, 15 connected between a transformer housing 2 and an array of parallel heat exchanging plates 12 having internal fluid passages.
