Novel heat exchanger structures

The utility model discloses a novel heat exchanger structures relates to heat exchanger technical field, including several heat exchange tube and the several piece that cracks, the several piece parallel arrangement that cracks, and the double -phase neighbour in the same vertical face to crack the piece interval the same, both sides are equipped with the tube seat that is used for placing the heat exchange tube respectively about the piece that cracks, the several heat exchange tube alternates in cracking the tube seat of piece, several heat exchange tube interconnect forms heat exchanger tube bundles, and the piece both sides tube seat that cracks corresponds and is equipped with tooth head I, tooth head II and tooth head III on the position respectively, tooth head I, tooth head are II the same with the width of tooth head III, and the difference in height is 0~5mm. The utility model discloses a change the heat transfer performance that the finned tube heat exchanger structure had promoted the heat exchang
