 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger tube assembly,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger assembling apparatus, and more particularly, to a heat exchanger tube assembling apparatus and a heat exchanger fin assembling apparatus for assembling a tube constituting a heat exchanger and a radiating fin provided between the tube and the radiating fin.

Generally, the heat exchanger is provided with a passage portion through which the heat exchange medium can flow, and is designed to perform heat exchange with the outside air while the heat exchange medium flows through the passage portion. The type of the heat exchange medium and the heat exchange medium A variety of methods have been developed depending on internal pressures such as a fin tube type, a serpentine type, a drawn cup type, and a parallel flow type. have

In such a heat exchanger, a heat exchanger core (generally called a Heater Core Builder, an Evap Core, a Radiator Core, or an Inter Cooler Core) in which heat exchange is mainly performed is composed of a header and a radiating fin and a tube which are stacked and fixed between the header.

The tube and the fin constituting the core of the heat exchanger are alternately stacked and assembled by the heat exchanger automatic assembling apparatus. In a conventional automatic heat exchanger automatic assembling apparatus, a tube distributed one by one by a tube dispenser is moved by a conveying chain and falls down to the bottom, and the fin material is milled by a fin mill between the dropped tube and the tube, The radiating fins are supplied to the space between the tube and the tube by the radiating fin supplying part, thereby compressing the heat exchanger core in which the tube and the radiating fin are stacked.
