Integrated Air/Oil Reservoir Cooler and Noise Reduction System

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...

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.

[0006]In accordance with one embodiment of the present invention, a cooling system for a pump is provided, which can include an inner tank that holds a hydraulic fluid that is used by the pump, an outer tank that surrounds the inner tank, a gap formed between an outer surface of the inner tank and an inner surface of the outer tank, and a baffle disposed in the gap, wherein the baffle redirects a flow of a cooling fluid which results in reduced flow that is introduced into the gap and can maintain an integrated relationship with the cooling capability.

[0007]In accordance with another embodiment of the present invention, a cooling system for a pump is provided, which can include a first means for containing that holds an operating fluid that is used by the pump, a second means for containing that surrounds the first means for containing, a gap formed between an outer surface of the first means for containing and an inner surface of the second means for containing, and a means for damping disposed in the gap, wherein the means for damping reduces a flow of a cooling fluid that is introduced into the gap.

[0008]In accordance with yet another embodiment of the present invention, a method of cooling a liquid in an inner tank is provided, which can include containing working fluid in the inner tank, introducing a cooling fluid into a gap created by the inner tank and an outer tank, cooling the working fluid in the inner tank with the cooling fluid by flowing the cooling fluid past the inner tank and a baffle coupled to the inner tank, and damps a noise with the baffle.

Problems solved by technology
