Heat exchanger

The utility model discloses a heat exchanger belongs to the heat exchanger field. It includes that a plurality of heat transfer units, entry pressure manifold and export pressure manifold constitute.The heat transfer unit be in the same place with a plurality of discontinuous fin connected by the pipeline. Discontinuous fin shape be the L type, and independent mutually between each discontinuousfin. Increased with the heat transfer area of air, has improved the heat transfer effect, and has not had the sealed cavity structure, can prevent piling up of dust in the use. 本实用新型公开了种热交换器，属于热交换器领域。它包括复数个换热单元、入口集流管和出口集流管构成。所述的换热单元由管道和复数个不连续翅片连接在起。所述的不连续翅片形状为L型，且各不连续翅片之间互相独立。增加了与空气的换热面积，提高了换热效果，且没有封闭腔体结构，使用过程中能防止灰尘的堆积。
