Abstract: An apparatus includes a heat exchange member at least partially defining a passageway, and structure defining a first plurality of holes and a second plurality of holes. The first and second pluralities of holes provide fluid communication from the passageway to the exterior of the apparatus, i.e., to the atmosphere. A blower is operatively connected to the heat exchange member and configured to blow air into the passageway. The apparatus is configured such that, when the heat exchange member is sufficiently positioned with respect to a campfire, air exiting the first plurality of holes is directed downward and away from the campfire and air exiting the second plurality of holes has an upward velocity component.
