| 摘要 |
The invention relates to a heat exchanger, especially to a solar energy collector having, on the one hand, means for collecting and absorbing solar radiation and, on the other hand, a circulating fluid to be heated or preheated passing through a duct of thermoconducting material arranged in the shape of a serpentine coil. This heat exchanger is characterised in that it comprises, for the circulation of the fluid to be heated or preheated, a tube made of a thermoconducting elastomer material 2 composed of rectilinear portions 3, 4, 5, 6 pushed into segments of thermoconducting rigid metal profiled parts 10, 11, 12, 13 securely fixed to the solar radiation collecting and absorbing means, and of visible elbowed portions 7, 8, 9 emerging on either side of the ends 14, 15, 16, 17, 18, 19 of the segments of rigid metal profiled parts 10, 11, 12, 13. The invention relates to solar collectors, radiators, preheaters, coolers, condensers, evaporators and the like. <IMAGE>
