Heat generator

摘要

A heat generator includes a heat generating member and a temperature compensating member made from different material. The heat generating member includes a heat flow output face for outputing heat flow and five heat flow insulation faces. The temperature compensating member encloses and contacts the heat generating member except the heat flow output face. A heat flow compensating circuit is electrically connected between the temperature compensating member and the heat generating member for maintaining a state of no heat flow flowing between the heat generating member and the temperature compensating member, whereby the heat energy of the heat flow outputing from the heat flow output face is equal to the heat energy of heat generated by the heat generating member.
