More Information
Summary:The invention relates to a heat exchanger. The heat exchanger comprises one or more heat exchanging parts which form an annular structure. Each heat exchanging part comprises a coil and a fin, wherein the fin is installed on the coil in a sleeving mode; the coil comprises at least two U-shaped pipes which are connected in series, the adjacent U-shaped pipes are connected through elbows, and the two ends, not connected with the elbows, of the U-shaped pipes serve as an inlet and an outlet of the heat exchanging part respectively. The heat exchanger is divided into multiple parts according to the structure of a draught fan, so that each air outlet of the draught fan corresponds to the corresponding heat exchanging part and the optimal heat exchanging effect is realized.
