Beschreibung
Zusammenfassung:	The invention relates to the technical field of fin type heat exchangers, in particular to a combined pipe type staggered fin type heat exchanger which comprises a heat exchange pipe set, a fin set and a frame, the fin set is connected to the outer side of the heat exchange pipe set, the frame is connected to the outer side of the fin set, and the heat exchange pipe set is composed of a front heat exchange pipe column and a rear heat exchange pipe column which are arranged in parallel front and back. The front heat exchange tube row comprises a plurality of oval heat exchange tubes, and the rear heat exchange tube row comprises a plurality of kidney-hole-shaped heat exchange tubes. The oval heat exchange tubes and the kidney-hole-shaped heat exchange tubes are arranged in a staggered mode, and the long axis direction of the oval heat exchange tubes and the length direction of the kidney-hole-shaped heat exchange tubes are the same as the inlet and outlet direction of air. The longitudinal sections of the oval
