The present invention relates to a heat exchanger, and has a heat transfer fin formed with a tube joint to surround the outer surface of the tube to reduce the weight and to a heat exchanger that can increase the production efficiency by simplifying the manufacturing process.

In recent years, interest in environmental protection and energy saving has been increasing worldwide in the automobile industry. As a result, not only research for improvement of environment and fuel efficiency but also development of vehicle suitable for light weight, miniaturization, high function and various driving environment And research and development are continuously carried out to increase the efficiency.

Generally, a heat exchanger is part of an air conditioner and is a device that absorbs one heat between two environments with a temperature difference and emits heat to the other. More specifically, the heat exchanger is a heating device for heating the air introduced by the air blowing device by heat exchange with an internal heat exchange medium, thereby absorbing heat from the outside and discharging warmed air into the room. When the air is cooled by heat exchange so that the cooled air is discharged to the room, it functions as a cooling device.

However, as shown in FIG. 1, the conventional heat exchanger is composed of a tube, a fin, a first header, a second header, a first tank, and a second tank, and thus requires a joining operation to join the tube and the header and the header and the tank. In addition, since the additional work is required to compensate for the shortcomings of the joining operation, the time required for manufacturing the heat exchanger is increased and the production cost is increased.

In addition, since the heat exchanger made of aluminum has a large weight, it lowers the overall energy efficiency.
