Abstract

An equipment case is provided. The case comprises a sealed housing unit configured to receive an item of equipment. Cooling means, associated with the housing unit, are provided for maintaining an operational thermal environment within the equipment case.

1 . A field equipment case comprising:
 a sealed housing unit configured to receive an item of equipment; and   cooling system associated with the housing unit for maintaining an operational thermal environment within the equipment case.   
     
     
         2 . A case according to  claim 1 , wherein the cooling system is directly connected to the housing unit. 
     
     
         3 . A case according to  claim 1 , wherein the cooling system is spaced from the housing unit but in fluid communication therewith. 
     
     
         4 . A case according to  claim 1  or  claim 2 , wherein the cooling system comprises a first fan, mounted within the housing unit, and a second fan, mounted external to the housing unit. 
     
     
         5 . A case according to  claim 4 , wherein the first fan is an axial fan. 
     
     
         6 . A case according to  claim 4 , wherein the second fan is a centrifugal fan. 
     
     
         7 . A case according to  claim 1  or  claim 2 , wherein the cooling system comprises a forced flow heat exchanger. 
     
     
         8 . A case according to  claim 1  or  claim 2 , wherein the cooling system is configured to establish a counter current thermal exchange mechanism between a fluid internal to the housing unit and a fluid external to the housing unit.
