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.
Claims17
An apparatus comprising:
- a heat exchange member at least partially defining a passageway;
- structure defining a first plurality of holes and a second plurality of holes providing fluid communication from the passageway to the exterior of the apparatus;
- a blower operatively connected to the heat exchange member and configured to blow air into the passageway;
- wherein 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.
A method comprising:
- providing an apparatus having heat exchange member defining a passageway, structure defining a first plurality of holes and a second plurality of holes that provide fluid communication from the passageway to the exterior of the apparatus, and a fan operatively connected to the heat exchange member and configured to blow air into the passageway;
- placing the apparatus relative to a fire such that the heat exchange member is in heat transfer relationship with the fire;
- causing air to flow through the passageway and out the first plurality of holes and the second plurality of holes;
- wherein air exiting the first plurality of holes moves away from the fire and air exiting the second plurality of holes has an upward velocity component.
An apparatus comprising:
- a heat exchange member at least partially defining a passageway;
- structure defining a first plurality of holes and a second plurality of holes providing fluid communication from the passageway to the exterior of the apparatus;
- a blower operatively connected to the heat exchange member and configured to blow air into the passageway;
- wherein the apparatus is configured such that air exiting the first plurality of holes includes a respective first velocity component that is away from a point;
- and
- wherein the apparatus is configured such that air exiting the second plurality of holes includes a second velocity component that is perpendicular to each of the respective first velocity components.
