Heat dissipation system

Abstract

A system for removing heat from heat load equipment including a re-circulating air handling unit for establishing an air curtain that flows up from and around the heat load equipment and one or more roof-mounted heat stratification housings disposed over the heat load equipment for receiving heat from the equipment. The heat generated from the equipment travels upwardly inside of and propelled by the air curtain. The heat stratification housing includes a plurality of heat transfer plates that extend between interior and exterior areas thereof. Water nozzles direct a spray on the heat transfer plates.

       9 . The system of  claim 1  including a heat reclaim system within the heat stratification housing. 
   
   
       10 . The system of  claim 1  including a drain pan on the inside of the heat stratification housing under the heat transfer plates. 
   
   
       11 . A building system for containing and dissipating heat from heat load equipment, said building system comprising:
 a building structure having a floor and a roof;   at least one heat stratification housing mounted at the roof and including at least one side wall that partially forms an internal housing area;   a plurality of heat transfer plates that each extend across the side wall of the stratification housing between the internal housing area and outside of the stratification housing;   a re-circulating air handling unit for establishing an air curtain that flows up from and around the heat load equipment;   said re-circulating air handling unit arranged at the floor of the building structure;   the at least one heat stratification housing being disposed over the heat load equipment for receiving heat generated from the equipment;   and a cooling system including a fan adjacent the heat stratification housing for drawing heat from the heat transfer plates.   
   
   
       12 . The system of  claim 11  wherein the plurality of heat transfer plates are supported in a parallel array, each heat stratification housing comprises a tower having opposite walls that each support an array of heat transfer plates, and each plate extends between the interior area of the housing and outside of the housing. 
   
   
       13 . The system of  claim 11  including an array of liquid nozzles disposed outside of the heat stratification housing and directed at the heat transfer plates to provide evaporative cooling. 
   
   
       14 . The system of  claim 13  including an evaporative cooling water manifold and a pump for directing water to the manifold and from the manifold to the nozzles. 
   
   
       15 . The system of  claim 14  including an external housing for the nozzles, a sump drain from the external housing and slotted air openings in the external housing for evaporative cooling. 
   
   
       16 . The system of  claim 11  wherein the re-circulating air handling unit directs air to floor diffusers that are disposed about the heat load equipment for establishing respective air curtains about the heat load equipment.
