Abstract
Each heat-exchange bank consists of at least two groups of flat, adjacent compartments provided for the circulation of a second fluid and separated by spaces for the circulation of a first fluid. Each compartment has lateral extensions placed in identical and opposite manner in two adjacent groups. The extensions are connected respectively in each group to a common admission manifold and to a common discharge manifold for the second fluid.
Claims9
A plate-type heat exchanger comprising a plurality of exchange banks each formed by a number of closed flat compartments having parallel walls and separated by spaces forming passages for the circulation of a first fluid, each compartment being employed for the circulation of a second fluid and provided with lateral extensions along two opposite sides of said compartment, wherein each heat-exchange bank is formed by at least two adjacent groups of compartments and each group comprises a plurality of adjacent compartments, the lateral extensions of the compartments being placed in identical manner in each group and in opposite manner in two adjacent groups, said lateral extensions being connected respectively in each group to a common admission manifold and to a common discharge manifold for the second fluid and wherein the compartments in each group are identical and arranged in opposite orientation from one group to the next with a symmetry with respect to an axial mid-plane at right angles to the plane of the compartments.
