Heat exchanger core with expanded metal spacer component

Abstract

A plate-type heat exchanger element for a plate-type air to air heat exchanger. The heat exchanger element comprises a heat exchange partition sheet and a spacer member comprising a corrugated mesh of expanded sheet metal. The corrugated mesh has an upstream side edge and a downstream side edge. The upstream side edge and the downstream side edge are folded over edges.

1 . A plate-type air to air heat exchanger, comprising 
 a plurality of stacked heat exchange partition sheets, each partition sheet being spaced apart from an adjacent partition sheet by respective spacing apart means so as to thereby form a plurality of first and second passageways for a first air stream and a second air stream to pass there through, respectively;    means for sealing two opposing sides of said first passageways thereby allowing the first air stream to pass there through in a first direction;    means for sealing two opposing sides of said second passageways thereby allowing the second air stream to pass there through in a second direction    and    wherein said spacing apart means for each of said first and second passageways comprises a corrugated mesh of expanded sheet metal having an upstream side edge and a downstream side edge    characterized in that said upstream side edge and said downstream side edge are folded over edges.    
   
   
       2 . A plate-type heat exchanger as defined in  claim 1  wherein said partition sheets are of material having heat conductivity and moisture permeability.  
   
   
       3 . A plate-type heat exchanger as defined in  claim 1  wherein said corrugated mesh is of aluminum.  
   
   
       4 . A plate-type heat exchanger as defined in  claim 2  wherein said partition sheets are of paper and said corrugated mesh is of aluminum.  
   
   
       5 . A plate-type heat exchanger element for a plate-type air to air heat exchanger, said heat exchanger element comprising a heat exchange partition sheet and a spacer member, said spacer member comprising a corrugated mesh of expanded sheet metal, said corrugated mesh having an upstream side edge and a downstream side edge characterized in that said upstream side edge and said downstream side edge are folded over edges.  
   
   
       6 . A plate-type heat exchanger element as defined in  claim 5  wherein said partition sheet is of material having heat conductivity and moisture permeability.  
   
   
       7 . A plate-type heat exchanger element as defined in  claim 5  wherein said corrugated mesh of aluminum.  
   
   
       8 . A plate-type heat exchanger element as defined in  claim 5  wherein said partition sheet is of paper and said corrugated mesh is of aluminum.  
   
   
       9 . A plate-type heat exchanger element for a plate-type air to air heat exchanger, said heat exchanger element comprising a heat exchange partition sheet and a spacer member, said spacer member comprising a corrugated mesh of expanded sheet metal, said corrugated mesh having an upstream side edge, a downstream side edge and a pair of opposed wall side edges connecting said upstream side edge to said downstream side edge,  
     characterized in that said upstream side edge and said downstream side edge are folded over edges  
     and  
     said heat exchange partition sheet is attached to said corrugated mesh at each of said wall side edges so as to define an exchanger air flow barrier element.  
   
   
       10 . A plate-type heat exchanger element as defined in  claim 9  wherein said partition sheet is of material having heat conductivity and moisture permeability.  
   
   
       11 . A plate-type heat exchanger element as defined in  claim 9  wherein said corrugated mesh is of aluminum.  
   
   
       12 . A plate-type heat exchanger element as defined in  claim 9  wherein said partition sheet is of paper and said corrugated mesh is of aluminum.  
   
   
       13 . A spacer member for a plate-type air to air heat exchanger, said spacer member comprising a corrugated mesh of expanded sheet metal having an upstream side edge and a downstream side edge  
     characterized in that said upstream side edge and said downstream side edge are folded over edges.  
   
   
       14 . A spacer member as defined in  claim 13  wherein said corrugated mesh is of aluminum.
