A heat exchanger for use with high pressure gases is disclosed which has a generally cylindrical shell through which pressurized gas is passed. A plurality of stacked, high pressure, fluid-carrying serial coils are arranged in parallel serpentine paths within a frame member to form a structurally independent unit. The frame member is attached to an inner support member provided within the shell to position and align the frame member and coils. In operation, the coils are arranged primarily transverse to the flow of the gas, yet, because of the serpentine path, the flow of fluid through the coils is counter to or parallel with the flow of gas in the shell. The frame member supports the serpentine coils and contains any vibrations of the coils caused by the shell gases passing over the coils.
