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.

1 . A cooling system for a pump, comprising:
 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 that results in reduction of the flow of the cooling fluid that is introduced into the gap and can maintain an integrated relationship with a cooling capability.   
     
     
         2 . The cooling system of  claim 1 , wherein the baffle reduces noise and any turbulence created by the flow of the cooling fluid in the gap. 
     
     
         3 . The cooling system of  claim 1 , wherein the baffle includes a first component and a second component that are angled in relation to each other. 
     
     
         4 . The cooling system of  claim 1 , wherein the outer tank further comprises a fluid opening that is used to introduce the cooing fluid into the gap. 
     
     
         5 . The cooling system of  claim 1 , wherein the cooling fluid is compressed air. 
     
     
         6 . The cooling system of  claim 1 , wherein the baffle is located after an entry point into the gap for the cooling fluid. 
     
     
         7 . The cooling system of  claim 1 , wherein the outer tank further includes an upper surface that forms a seal with a portion of the inner tank. 
     
     
         8 . The cooling system of  claim 1 , wherein a maximum temperature drop in the cooling system occurs at the fluid opening designed to receive cooling fluid into the gap. 
     
     
         9 . A cooling system for a pump, comprising:
 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.   
     
     
         10 . The cooling system of  claim 9 , wherein the means for damping reduces noise and any turbulence created by the flow of the cooling fluid in the gap. 
     
     
         11 . The cooling system of  claim 9 , wherein the means for damping includes a first component and a second component that are angled in relation to each other. 
     
     
         12 . The cooling system of  claim 9 , wherein the second means for containing further comprises a fluid opening that is used to introduce the cooing fluid into the gap. 
     
     
         13 . The cooling system of  claim 9 , wherein the cooling fluid is compressed air. 
     
     
         14 . The cooling system of  claim 9 , wherein the means for damping is located after an entry point into the gap for the cooling fluid. 
     
     
         15 . The cooling system of  claim 9 , wherein the second means for containing further includes an upper surface that forms a seal with a portion of the first means for containing. 
     
     
         16 . The cooling system of  claim 9 , wherein a maximum temperature drop in the cooling system occurs at fluid opening designed to receive cooling fluid into the gap. 
     
     
         17 . A method of cooling a liquid in an inner tank, comprising the steps of:
 containing a 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 pass the inner tank and a baffle coupled to the inner tank; and   damping a noise with the baffle.   
     
     
         18 . The method of cooling of  claim 17  further comprising existing the cooling fluid from a side of the outer tank. 
     
     
         19 . The method of  claim 17 , wherein the cooling fluid is compressed air. 
     
     
         20 . The method of  claim 17 , further comprising damping a vibration with the baffle.
