Heat exchanger

Abstract

There is provided a heat exchanger comprising: a housing comprising: an inlet at a proximal end for receiving a first fluid; and an outlet, downstream of the inlet at the distal end of the housing, through which the fluid is configured to exit the housing; and a plurality of heat exchanger cores within the housing, wherein the plurality of heat exchanger cores meet at a junction and diverge from each other towards one of the inlet or the outlet of the housing; wherein the plurality of heat exchanger cores comprises a plate fin arrangement; and, wherein the plurality of heat exchanger cores comprise one or more first flow paths through which the first fluid can pass through the heat exchanger cores, in use.

What is claimed is: 
     
         1 . A heat exchanger comprising:
 a housing comprising:   an inlet at a proximal end for receiving a first fluid; and   an outlet, downstream of the inlet at the distal end of the housing, through which the fluid is configured to exit the housing; and   a plurality of heat exchanger cores within the housing, wherein the plurality of heat exchanger cores meet at a junction and diverge from each other towards one of the inlet or the outlet of the housing;   wherein the plurality of heat exchanger cores comprises a plate fin arrangement; and   wherein the plurality of heat exchanger cores comprise one or more first flow paths through which the first fluid can pass through the heat exchanger cores, in use.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the housing comprises a substantially square-shaped cross section. 
     
     
         3 . The heat exchanger according to  claim 1 , wherein a length of the heat exchanger is approximately four times the length of a width of the heat exchanger. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein each of the plurality of heat exchanger cores comprises a core inlet for receiving a second fluid and a core outlet through which the second flow is configured to exit the heat exchanger core. 
     
     
         5 . The heat exchanger according to  claim 4 , wherein core inlet of the heat exchanger core is arranged towards the distal end of the housing. 
     
     
         6 . The heat exchanger according to  claim 4 , wherein the outlet of the heat exchanger core is arranged at the junction of the heat exchanger cores. 
     
     
         7 . The heat exchanger according to  claim 4 , wherein the heat exchanger core is arranged in a counterflow arrangement with respect to the first fluid. 
     
     
         8 . The heat exchanger according to  claim 1 , wherein the heat exchanger cores diverge from each other at an angle of between 60 to 160 degrees. 
     
     
         9 . The heat exchanger according to  claim 1 , wherein the heat exchanger core comprises a plurality of layers. 
     
     
         10 . The heat exchanger according to  claim 1 , comprising one or more aerofoils configured to guide the flow of the first fluid. 
     
     
         11 . The heat exchanger according to  claim 1 , wherein the heat exchanger cores diverge from each other towards the inlet of the housing. 
     
     
         12 . The heat exchanger according to  claim 1 , wherein the heat exchanger cores diverge from each other towards the outlet of the housing. 
     
     
         13 . The heat exchanger according to  claim 1 , wherein the weight of the heat exchanger is between 9 kg and 12 kg. 
     
     
         14 . An aircraft comprising the heat exchanger according to  claim 1 .
