    • A flat plate solar collector comprising a planar glazing and a rear housing formed into a number of semi-circular cells to receive fin-tube absorbers with minimal direct contact, the glazing being a low iron glass with an anti-reflective exterior coating and a low emissivity interior coating, the glazing being directly supported by the rear housing cells, the interior wall of the rear housing and the lower side of the fin-tube absorber having low emissivity surfaces. At least one radiation shield member having low emissivity upper and lower surfaces is positioned between the fin-tube absorber and the rear housing. The collector is evacuated by atmosphere control means also capable of reintroducing atmosphere into the collector to control internal temperature.
    • 1.一种平板太阳能集热器(10),包括形成为多个半圆形单元(14)以接收具有最小直接接触的翅片管吸收器(21)的平面玻璃窗(12)和后壳体(13),所述玻璃窗 (12)是具有防反射外涂层(31)和低发射率内涂层(32)的低铁玻璃,所述窗玻璃(12)由所述后壳体单元(14)直接支撑,所述 后壳体(13)和翅片管吸收器(21)的下侧具有低辐射率表面。 在翅片管吸收器(21)和后壳体(13)之间设置至少一个具有低发射率上表面和下表面的辐射屏蔽部件(51)。 收集器(10)由气氛控制装置(99)抽空,该装置还能够将气氛重新引入收集器(10)以控制内部温度。
