| 摘要 |
A solar furnace heating system is disclosed which is characterized by the provision of novel rotary vane-type heat collector elements arranged in a heat collecting chamber beneath the generally vertical transparent wall of a housing. The fluid to be heated is conveyed across the heat collecting chamber in heat-transfer relationship with the rotary heat collector elements, and then to a heat storage chamber contained in the bottom portion of the housing. After the temperature of the fluid in the heat storage chamber reaches a given value, heated fluid from the heat storage chamber may be conveyed, upon demand, to the enclosure to be heated. In one embodiment, the heat collector elements are mounted for free rotation in the housing by the fluid that is conveyed through the heat collecting chamber. In a second embodiment, means are provided for rotatably driving the heat collector elements in synchronism.
