System and method for cooling of an aftertreatment module

Abstract

A cooling system for an aftertreatment module located within an enclosure is provided. The cooling system includes an exhaust outlet line and a venturi arrangement provided in cooperation with the exhaust outlet line. The venturi arrangement is spaced from a downstream portion of the exhaust outlet line. Moreover, the venturi arrangement relative to the downstream portion of the exhaust outline line is configured to expel heated air from the enclosure.

We claim: 
     
         1 . A cooling system for an aftertreatment module located within an enclosure, the cooling system comprising:
 an exhaust outlet line; and   a venturi arrangement provided in cooperation with the exhaust outlet line, the venturi arrangement being spaced from a downstream portion of the exhaust outlet line, wherein the venturi arrangement relative to the downstream portion of the exhaust outline line is configured to expel heated air from the enclosure.   
     
     
         2 . The cooling system of  claim 1 , wherein the exhaust outlet line further comprises a first section and a second section, the second section provided downstream of the first section, wherein the first section and the second section are in fluid communication via the venturi arrangement. 
     
     
         3 . The cooling system of  claim 2 , wherein the first section is connected to an outlet port of the aftertreatment module. 
     
     
         4 . The cooling system of  claim 2 , wherein the venturi arrangement is coupled to the first section using a mechanical fastener. 
     
     
         5 . The cooling system of  claim 2 , wherein the first section and the second section are made of metal. 
     
     
         6 . The cooling system of  claim 1  further comprising a plurality of support structures provided in association with the venturi arrangement, the plurality of support structures configured to maintain a concentric alignment of the venturi arrangement with respect to the downstream portion of the exhaust outlet line. 
     
     
         7 . The cooling system of  claim 1  further comprising a hooded structure which at least partially defines the enclosure and having at least one opening disposed therein, whereby air is circulated through the enclosure through the at least one opening in response to the heated air being drawn into the space between the venturi arrangement and the downstream portion of the exhaust outlet line. 
     
     
         8 . The cooling system of  claim 1  further comprising a vent provided on the enclosure and in cooperation with the downstream portion of the exhaust outlet line, the vent being configured to release the heated air from the enclosure. 
     
     
         9 . The cooling system of  claim 1 , wherein the venturi arrangement is made of metal. 
     
     
         10 . A method for cooling an aftertreatment module located within an enclosure, the method comprising:
 providing a venturi arrangement in cooperation with an exhaust outlet line of the aftertreatment module, the venturi arrangement being spaced from a downstream portion of the exhaust outlet line;   drawing in heated air within the enclosure into the space between the venturi arrangement and the downstream portion of the exhaust outlet line; and   expelling the heated air from the enclosure.   
     
     
         11 . A machine comprising:
 a power source;   a frame;   an aftertreatment module mounted within an enclosure located on the frame; and
 a cooling system for the aftertreatment module, the cooling system comprising:
 an exhaust outlet line; and 
 a venturi arrangement provided in cooperation with the exhaust outlet line, the venturi arrangement being spaced from a downstream portion of the exhaust outlet line, wherein the venturi arrangement relative to the downstream portion of the exhaust outline line is configured to expel heated air from the enclosure. 
 
   
     
     
         12 . The machine of  claim 11 , wherein the exhaust outlet line further comprises a first section and a second section, the second section provided downstream of the first section, wherein the first section and the second section are in fluid communication via the venturi arrangement. 
     
     
         13 . The machine of  claim 12 , wherein the first section is connected to an outlet port of the aftertreatment module. 
     
     
         14 . The machine of  claim 12 , wherein the venturi arrangement is coupled to the first section using a mechanical fastener. 
     
     
         15 . The machine of  claim 12 , wherein the first section and the second section are made of metal. 
     
     
         16 . The machine of  claim 11  further comprising a plurality of support structures provided in association with the venturi arrangement, the plurality of support structures configured to maintain a concentric alignment of the venturi arrangement with respect to the downstream portion of the exhaust outlet line. 
     
     
         17 . The machine of  claim 11  further comprising a hooded structure which at least partially defines the enclosure and having at least one opening disposed therein, whereby air is circulated through the enclosure through the at least one opening in response to the heated air being drawn into the space between the venturi arrangement and the downstream portion of the exhaust outlet line. 
     
     
         18 . The machine of  claim 11  further comprising a vent provided on the enclosure and in cooperation with the downstream portion of the exhaust outlet line, the vent being configured to release the heated air from the enclosure. 
     
     
         19 . The machine of  claim 11 , wherein the venturi arrangement is made of metal.
