ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for assembling a heat exchanger, and more particularly, to an apparatus for assembling a drawn-cup type heat exchanger.
2. Description of the Related Art
FIG. 1
shows an example of a general drawn-cup type heat exchanger. As shown in the drawing, a drawn-cup type heat exchanger
10
includes tube assemblies
13
where a tank portion
11
is formed and a radiation path portion
12
through which heat exchange medium passes is formed, a fin
14
inserted between the tube assemblies
13
, an end plate
15
disposed at both side portions of the heat exchanger, a special tube assembly
16
having a baffle for changing flow of heat, and a manifold tube assembly
18
where a manifold is installed, which are stacked and braze-combined.
To assemble the drawn-cup type heat exchanger
10
having the above structure, the fin
14
is inserted between two sheets of molding plates completely molded to form a fin plate assembly. An end plate assembly formed by inserting the fin
14
between the plate-fin assembly, the end plate
15
and a molding plate, a special plate assembly formed by inserting the fin
14
between a plate in which the tank portion
11
at one side thereof is blocked for baffle, and a manifold plate assembly to which a manifold is coupled, are stacked and braze-combined.
However, in manufacturing the drawn-cup type heat exchanger, each part constituting the heat exchanger is separately manufactured and the assembly and stacking thereof is manually performed using predetermined tools. Thus, numerous work steps are required during the manufacture of the heat exchanger, and productivity thereof is lowered.
SUMMARY OF THE INVENTION
To solve the above problems, it is an objective of the present invention to provide an apparatus for assembling a heat exchanger which enables manufacture and assembly of parts forming a drawn-cup type heat exchanger in a continuous process so that productivity in manufacturing the heat exchanger can be improved and a rate of defective products can be drastically reduced.
Accordingly, to achieve the above objective, there is provided a heat exchanger assembling apparatus comprising a main conveyer for transferring a tray, at least one fin transfer conveyer and one molding plate transfer conveyer, installed at one side of the main conveyer to be parallel thereto and having a predetermined length, a plurality of fin plate assembling devices, installed between the fin transfer conveyer and the molding plate transfer conveyer in a lengthwise direction of the main conveyer, a fin molding device, connected to the fin transfer conveyer, for molding a fin, a plate molding device, installed at one side of the main conveyer, for manufacturing a plate and supplying the manufactured plate to the molding plate transfer conveyer, a fin molding plate supply device for supplying the fin molding plate assembly assembled by the fin plate assembling devices to the tray intermittently transferred by the main conveyer, an end plate assembly supply device, a special plate assembly supply device and a manifold plate assembly supply device, sequentially installed at an outlet portion of the main conveyer, for respectively supplying an end plate assembly, a special plate assembly and a manifold plate assembly to the tray, and a picking device, installed at an outlet portion of the main conveyer, for picking a heat exchanger assembly supported at the tray and loading the picked heat exchanger assembly in a cleaning tray.
In the present invention, the heat exchanger assembling apparatus further comprises a cleaning device for cleaning a heat exchanger assembly completely picked, an installation device for installing the completely cleaned heat exchanger assembly, and a heat exchanger loading and unloading device for loading and unloading the heat exchanger installed at the brazing jig in and from the brazing tray.
