Abstract:
1. A heat exchanger comprising: a body including (i) a center portion defining a surface capable of thermal coupling to a heat conductor and formed of a first thermally conductive material; (ii) a surrounding portion thermally coupled to the center portion, the surrounding portion formed of a second thermally conductive material and defining therethrough a fluid passage through which a heat exchanging fluid may be circulated so that heat can be transferred between the heat exchanging fluid and the body, the fluid passage extending about the center portion; and (iii) heat exchange fins extending out into the fluid passage about which the heat exchanging fluid circulates when moving through the fluid passage, the heat exchange fins defining planar side surfaces over which the heat exchanging fluid passes; an inlet to the fluid passage and an outlet from the fluid passage.
