HEAT EXCHANGER FOR COOKING APPARATUS

摘要

A heat exchanger (10) for use in cooking applications, comprising a housing (12), a cooking medium chamber (14) in the housing (12) for passage of cooking medium through the housing (12) during the heat exchange process; and a heat exchange element (16). The heat exchange element (16) is formed to define a generally spiral path for cooking medium to pass through the cooking medium chamber (14) during the heat exchange process. Cooking apparatus (100), and methods of operation of cooking apparatus (100) including such heat exchangers (10; 22) are described.
