Title:
SOLAR HEAT COLLECTOR
Document Type and Number:
Japanese Patent JP3273361
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To greatly decrease heat loss from the back surface of the heat absorbing plate of a solar heat collector in order to obtain a flat plate type solar heat collector capable of being used as a heat source of 100°C or higher without converging solar light by a lens or the like.
SOLUTION: The inner part of a flat plate type solar heat collector has high vacuum of 0.1 Pa or lower. Then, at least one partition plates formed with a plate material, which is formed with a glass, plastic or metallic plate material on which a reflecting surface is made of metal material of a good electrical conductor with a vacuum deposition, a plating or a sputtering method, are provided therein between a heat absorbing plate and the bottom surface of a casing opposed thereto. Thus, wasteful heat loss escaping toward the casing due to the conduction and radiation of heat from the heat absorbing plate is extremely reduced.
