熱容積式換熱器是一種新型高效換熱設備，熱水機組哪家好它集波紋管換熱器和容積式換熱器的有限于一體，采用薄壁不銹鋼波紋管作為換熱元件。由于波紋管獨特的波形，實現了管內外充分湍流，打破了邊界層，降低了管壁熱阻，提高了管內的給熱系數。波紋管即熱容積式換熱器在溫差應力的作用下，波紋在軸向存在伸縮變形，使管壁不宜結垢，即使結垢，也會由于管子的伸縮而脫落。因此，該系列容積式換熱器具有如下特點：1、換熱效率高。2、防垢、除垢能力強。3、儲水量大，出水溫度恒定。4、出水能力是其他容積式換熱器的3-5倍。5、體積小，占地面積小，可節省占地面積30%-80%。波紋管即熱容積式換麗水熱水機組哪家好熱(re)器(qi)分(fen)為立(li)式與(yu)臥(wo)式兩種系列，按(an)照熱(re)源介質分(fen)為汽水型(xing)與(yu)水水型(xing)。
