Universal heat exchanger

Abstract

A heat exchanger (100) having a plurality of plates (101) manufactured preferably but not limiting to the stamping process, the plates has been configured to accommodate the internal fins (106). The plates (101) also define plurality of the passages (102) for flowing at least two fluids. A plurality of conduits (103) fluidly coupled to a first end and second of the end of the plates (101) which allows the flow of the fluids. At least one inlet (104) coupled to a first end, and at least one outlet (105) coupled to the second end of the plurality of plates (101) configured to allow the flow of the fluids wherein each fluid flow in a different direction from the other, a plurality of inner fins (106) disposed on a surface of each of the plurality of plates (101) for increasing the surface to volume ratio of the first and second fluid to achieve pre-defined thermal performance.

We claim: 
     
         1 ) A heat exchanger ( 100 ) comprising:
 a plurality of plates ( 101 ) configured to define a plurality of flow passages for flowing at least two fluids;   a plurality of conduits fluidly coupled to a first end and a second end of the plates to allow the flow of the fluids;   at least one inlet coupled to the first end, and at least one outlet coupled to the second end of the plurality of plates configured to allow the flow of the fluids wherein each fluid flow in a different direction from the other;   a plurality of inner fins disposed on a surface of each of the plurality of plates for increasing the surface to volume ratio of the first and second fluid to achieve pre-defined thermal performance.   
     
     
         2 ) The heat exchanger as claimed in  claim 1 , wherein the fluids flow in the opposite direction from the other. 
     
     
         3 ) The heat exchanger as claimed in  claim 1 , wherein the fluids are either a refrigerant or a coolant. 
     
     
         4 ) The heat exchanger as claimed in  claim 1 , wherein the plurality of the inner fins are non-louvered straight wavy fins configured to produce laminar flow. 
     
     
         5 ) The heat exchanger as claimed in  claim 1 , wherein the inner fins are disposed on the plain plate area. 
     
     
         6 ) The heat exchanger as claimed in  claim 1 , wherein the plurality of plates are dumbbell-shaped stamped plates capable to interlock while stacking on each other. 
     
     
         7 ) The heat exchanger as claimed in  claim 1 , wherein the plurality of plates are having a pre-defined specific thickness. 
     
     
         8 ) The heat exchanger as claimed in  claim 1 , wherein a stiffener is placed in one of the plates of the heat exchanger for high-pressure application. 
     
     
         9 ) The heat exchanger as claimed in  claim 1 , wherein the plate has a plurality of embossing and a plurality of fin stoppers. 
     
     
         10 ) The heat exchanger as claimed in  claim 1 , wherein the heat exchanger work as three different heat exchangers such as Chiller or W-Condenser or Plate IHX as per the requirement by changing the inlet/outlet connections with a common core.
