摘要

Heat exchanger 10 has first and second heat exchange elements 11,12 each with respective inlet 14 and outlet 15. Thermoelectric units (typically Peltier elements) 17 are located side by side and clamped between elements 11,12. Flow passages in the elements 11,12 are formed by sheet metal inserts arranged in cavities in the elements (not shown).
