A self-powered fan for circulating air for use in cooperation with a heat source, such as a wood stove, and having a first heat transfer member thermally and physically connected with the heat source. The fan blades operably create a first or warm air flow and a second or cooler air flow. The fan has a second heat transfer member with a thermocouple module structure located between the two heat transfer members. The first heat transfer member is of suitable material, size, mass and shape as to provide a suitable temperature gradient between the thermocouple structure and the heat source to operably allow of such sufficient heat transfer from the first heat transfer member to the thermocouple to generate sufficient power to effect rotation of the blades, but not to cause thermal damage to the thermocouple structure. The fan blades are constructed and arranged to cause a portion of the second air flow to be drawn past the first heat transfer member to effect a cooling heat transfer effect upon the first heat transfer member. The improvement is wherein the motor located on the first transfer member adjacent a side of the thermocouple structure remote from the second transfer member does not hinder the second air flow, and is suitably located as to not be operably thermally damaged by the first heat transfer member or the heat source. |
