Abstract
A forced convection heat exchanger for warming articles such as baby bottles is provided comprising a container having walls extending upwardly from a bottom end to define an open top end. A platform to receive and support the article to be warmed is mounted within the container spaced apart from the container bottom end. A plurality of spacers extend inwardly from the walls and upwardly from the platform. First drain openings are provided extending through the platform and second drain openings are provided within the walls below the platform adjacent the bottom end. The area of the platform relative to the total cross-sectional area of the first drain openings is dimensioned so as to provide a standing head of water under turbulent flow conditions within the container substantially up to the container open top end when the container receives an average flow of water from a tap.
