Heat exchanger and heat pump cycle

摘要

The heat exchanger includes conduit systems for coolant and cooled fluid, thermally coupled for heat transfer. It has several sections (17) hydraulically coupled to each other in parallel and/or series. In every section, at least one fluid channel is formed by metal sheet (9) of U-, V- or W-shaped cross section, closed at the ends by another metal sheet (12). The coolant runs in a conduit (15) parallel to the longitudinal axis of the fluid channel.
