Benefits of technology

[0005]The foregoing needs are met, to a great extent, by the present invention, wherein in one aspect an apparatus is provided that in some embodiments include a cooling system. An inner tank holds a working fluid and a gap is created between the inner tank and an outer tank. A baffle is disposed within the gap to damp the noise and any vibration caused by the introduction of a cooling fluid into the gap. The cooling fluid will cool the working fluid in the inner tank and the heat dissipated by the baffle, and the outer shell.

Problems solved by technology

However, conventional cooling systems are not performing as required and the pumps are running too hot.

Embodiment Construction

[0014]The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. An embodiment in accordance with the invention provides a pump, such as an air / hydraulic pump that includes a cooling system that cools a working fluid such as hydraulic fluids used in the pump and reduces noise during the cooling system's operation.

[0015]The working fluid can be any fluid including, for example, hydraulic fluids, oils, lubricants, water, phosphate ester, water-based ethylene glycol compounds, and silicone fluids. Three most common types of hydraulic liquids are petroleum-based, synthetic fire-resistant, and water-based fire-resistant. The working fluid can be synthetic, naturally occurring or a combination thereof. As noted, any working fluid can be used with the invention and hydraulic fluid is just one exemplary fluid that can be used with invention. The cooling system combines a noise and vibration abatement system whi...

Abstract

A cooling system and method are provided to cool a working fluid in an inner tank. The cooling system includes an outer tank and a gap formed between the inner tank and outer tank. The cooling system further includes a baffle disposed in the gap to damp a flow of a cooling liquid that is introduced into the gap. The baffle is designed to decrease the noise and turbulence that can occur with the introduction of the cooling liquid into the gap.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a reservoir cooler. More particularly, the present invention relates to an integrated air / oil reservoir cooler and noise reduction system.BACKGROUND OF THE INVENTION[0002]Air / hydraulic pumps are used when air is the preferred power source or where electricity is not readily available. Further, these pumps are ideally used in petrochemical and mine applications and flammable and explosive environments. The pumps that are high performance provide consistently high hydraulic flow and pressure for faster tool operation.[0003]During use, the hydraulic fluid in the reservoir can heat up and must be cooled down in order for the pump to effectively operate. However, conventional cooling systems are not performing as required and the pumps are running too hot. Further, the motor of the pumps often include muffler systems to reduce noise that often ice up during operation due to freezing caused by moisture in the ambient a...
