<p>The invention relates to a heat exchanger (10) comprising hoses (11) to be positioned vertically. The hoses (11) are mounted to a transverse perforated upper mounting plate (21) at their upper ends and the hoses are mounted to a transverse perforated lower mounting plate (31) at their lower ends. The hoses are made of thin flexible material like plastic sheet. The upper mounting plate (21) forms a cover of the feed tank (20) of the liquid to be evaporated. The bottom (22) of the feed tank is provided with lead-through holes (24) for the hoses, and the diameter of the lead-through holes (24) is larger than the outer diameter of the hoses (11) so as to allow liquid to flow down through the gap (25) formed between the outer surface of the hose and the plate. According to the invention, one or more redistributing tanks (50) provided with a perforated bottom plate (51) are fitted between the feed tank (20) of the liquid to be evaporated and the condensate receiver (30).</p> |
