PURPOSE:To make temperature difference between a heat-receiving zone and a condensing zone increase, improving the efficiency of evaporation, by making a circulation path for vapor by means of setting a insulator board in the middle of the unit opposite to a light-transmitting plane. The unit has the heat-receiving zone on the insulator board and the condensing zone at the bottom of the unit. Water vapor evaporated at the heat-receiving zone is forced to circulate by use of a fan. |
