The utility model relates to the heat exchange technical field, promotes a connecting structure comprising fins and heat pipe between the fins of the heat exchanger and heat pipe, the fins are equipped with holes, which make the heat pipe connect with fins, The utility model is characterized in that a weldable riveting ring is located tightly and suitably in the holes, the internal diameter of the riveting ring can cross the heat pipe, the riveting ring is connected with the heat pipe through the welding materials. The riveting ring in the utility model is riveted with fins through the interference, and the material quality of the riveting ring can accord or resemble with the material quality of fins, can not loose because of the thermal expansion and cold-reducing, and the connecting mode between riveting ring and the weldment is the welding, which reserves the advantages of conventional weld, simultaneously avoids the cost increase of plating fins, achieves a goal of the effective connection of the heat pipe and fins and reducing the cost.
