Problems solved by technology
However, the continued increase in the price of copper has led to the need for alternative, lower cost materials
[0004] Aluminum has replaced copper as the preferred material of construction in other heat exchangers, such as automotive and commercial radiators, but aluminum has not been successful in replacing copper in such heavy-duty heat exchangers
Aluminum has much lower strength than copper, leading to concerns about its durability
This is especially problematic in the art when individual tube assemblies need to be removed and inserted, as damage can occur during such manipulations
In addition, the joining of aluminum parts requires much higher temperatures than the soldering of copper, which leads to manufacturing difficulties

Abstract
A tube assembly for a heat exchanger by disposing a first corrugated fin structure between one wide flat side of the tube and a side plate, and disposing a second corrugated fin structure on the tube made between the other wide flat side of the and the other side panel. Pressure is applied to opposite sides of the side plates to bring the crests and troughs of the corrugated fin structures into contact with the side plates and the wide flat side plates, and the assembly is then brazed.
Description
technical field [0001] Generally, the present invention relates to tubes for heat exchangers, and fin and tube assemblies, and methods of making them. Background technique [0002] As is well known, large heat exchangers comprise separate, individually replaceable tube assemblies having tubes for conveying a first fluid and for transferring heat from a second fluid to said first fluid or using A secondary heat transfer surface area that transfers heat from the first fluid to the second fluid. For example, Murray in US Patent No. 3,391,732 and Neudeck in US Patent No. 4,236,577 have described this type of heat exchanger for transferring waste heat from engine coolant to the air as a heavy equipment radiator. The tube assemblies used in these heat exchangers have a central finned section for heat exchange and unfinned cylindrical end sections for insertion into sealing grommets. [0003] Heat exchanger tube assemblies of the type described above are usually constructed of co...
