Document Type and Number:
Japanese Patent JP2005536706
Kind Code:
A
Abstract:
The present invention provides a fluid-to-fluid through-the-wall heat exchanger for condensation of a vapour in a primary fluid stream, characterised in that the flow path (5) of the primary fluid stream is defined by an inner cylinder (1), an outer cylinder (2) arranged concentrically to and surrounding the inner cylinder, and a helical space holder (3) arranged between the inner and the outer cylinder. This condenser is easily coated such that all wetted materials are corrosion resistant. Compared to other condensers with identical ratings, this heat exchanger shows a smaller flow resistance, resulting in a smaller power demand of the blower or pumps. It is therefore particularly suitable for fuel cell systems where the condensed water has to be recirculated in the system and where purity demands are high and parasitic blower power should be minimal. The manufacturing of such a double envelope cylindrical heat exchanger is particularly simple and cost effective.
