AI Technical Summary

Problems solved by technology

Oil bath technology has proven unreliable at lubricant film thicknesses less than approximately 0.0254 mm (0.001 in)
Additionally, these techniques inherently generate large amounts of waste and offer little to no control over the application process

Embodiment Construction

[0012] figure 1 is a schematic diagram of a system 10 for manufacturing heat exchangers from sheet metal stock, the system 10 including a die press 12 , an uncoiler 14 , a lubrication system 16 and a sheet metal stock 18 . exist figure 1 Among them, the die press 12 is configured to receive sheet metal stock 18 and form it into, for example, corrugated sheets 19 from which heat exchanger fins may be constructed. The uncoiler 14 is configured to supply sheet metal stock 18 to the die press 12 . In some embodiments, the uncoiler 14 is a passive device and the printer 12 is configured to pull the sheet metal stock 18 from the uncoiler 14 . The sheet metal raw material 18 may be, for example, a thin sheet of aluminum from which heat exchanger fins are generally constructed. Without proper lubrication during the stamping process, the sheet metal stock 18 may gall and crack as it is formed into the profile of the die in the die punch 12 . Embodiments of the invention thus includ...

Abstract

Embodiments according to this disclosure include methods and systems for lubricating sheet metal stock by wiping a controlled amount of lubricant onto the surfaces of the sheet metal with strips of material, such as felt, saturated with the lubricant. The lubrication methods and systems disclosed herein can also provide for control of the pressure at which the lubricant is delivered, the volume of lubricant delivered, and the frequency lubricant is delivered to the felt strips. The lubricant is delivered to the felt strips at a number of locations and the felt material is configured to naturally wick the lubricant from the injection sites to the spaces between injection sites to substantially saturate the entire strip.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from US Provisional Application Serial No. 61 / 105,285, filed October 14,2008. Background technique [0003] Air conditioners and heat pumps typically employ vapor-compression refrigerant systems to cool, or to cool and heat, the air supplied to a climate-controlled comfort zone, such as in a residence, office building, hospital, school, restaurant, or other institution. Conventionally, such vapor compression systems include a compressor, condenser, expansion device, and evaporator, interconnected by refrigerant lines in a closed refrigerant circuit and arranged according to the vapor compression cycle (i.e., heating or cooling) employed . Condensers and evaporators include heat exchangers that are typically used to add heat to or remove heat from the refrigerant flowing through the unit. [0004] Heat exchangers employed in condensers and evaporators typically include a number of coils ...
