Abstract

Heat exchanger matrices of the folded strip type are set in an elongated V onfiguration inside a tubular casing. They are held in position by braces between opposite cover plates and between other cover plates and the casing, which braces also operate as partition walls for separating inlet and outlet channels of one of the media. The cooler of the media has inlet ducts downwards on the edges of the space inside the V and an outlet duct for upward flow at the center of the space inside the V. The other medium, which is hotter, but under less pressure, has inlet ducts with upward flow at the center of the spaces outside the V and outlet ducts with downward flow at the edges of the spaces outside the V. The hotter parts of the heat exchanger are in the middle of the structure. Bellows-type thermal expansion compensators seal the edges of the V against the casing.
