| 摘要 |
The invention relates to a solar thermal collector for heating a fluid to be heated (600), comprising:—a thermally insulating body (1);—a light transparent barrier (2);—a heat accumulator (3) comprising a thermal accumulating material (30), and—a heat exchanger (5) designed for transmit thermal energy from the thermal accumulating material to the fluid to be heated (600), wherein heat exchanger (5) is formed by a pileup of die-forged metal sheets and wherein the thermal accumulating material consists of a phase transfer material comprising a salt solutions based hydrogel and gelling agents. |
