PURPOSE:To improve condensing and heat collection effect with simple structure by arranging plane reflex mirrors or concave reflex mirrors of small curvature at four sides of a rectangular heat collecting plate and by further installing triangular planes or concave reflex mirrors at four corners. CONSTITUTION:At four sides of rectangular or square heat collecting plate 1, four rectangular plane or concave reflex mirrors 2 are arranged and at four corners, plane or concave reflex mirrors 3 are installed. Consequently, more than the three- fold magnification of condensation and the nearly five-fold amount of heat collection is realized; the structure is simple and durable and assembling and movement are facilitated. |
