Heat exchanger

Abstract

A heat exchanger is disclosed. The heat exchanger of the present disclosure includes a first heat exchanger into or from which a first fluid flows or is discharged, and a second heat exchanger into or from which a second fluid flows or is discharged, the second heat exchanger being adjacent to the first heat exchanger, and the first heat exchanger and the second heat exchanger are rolled together in a roll shape, are alternately disposed in a radial direction, and are in contact with each other.

What is claimed is: 
     
         1 . A heat exchanger comprising:
 a first heat exchanger into or from which a first fluid flows or is discharged; and   a second heat exchanger into or from which a second fluid flows or is discharged, the second heat exchanger being adjacent to the first heat exchanger,   wherein the first heat exchanger and the second heat exchanger are rolled together in a roll shape, are alternately disposed in a radial direction, and are in contact with each other.   
     
     
         2 . The heat exchanger of  claim 1 , wherein the first heat exchanger further comprises:
 a first inner header having a first inlet into which the first fluid flows;   a first outer header having a first outlet from which the first fluid is discharged and being spaced apart from the first inner header; and   a first heat exchange pipe configured to provide a flow path for the first fluid between the first inner header and the first outer header, the flow path connecting the first inner header and the first outer header.   
     
     
         3 . The heat exchanger of  claim 2 , wherein the second heat exchanger further comprises:
 a second outer header having a second inlet into which the second fluid flows;   a second inner header having a second outlet from which the second fluid is discharged and being spaced apart from the second outer header; and   a second heat exchange pipe configured to provide a flow path for the second fluid between the second outer header and the second inner header, the flow path connecting the second outer header and the second inner header.   
     
     
         4 . The heat exchanger of  claim 3 , wherein a flow path for the first fluid is formed in an internal space of the first inner header,
 the flow path of the first fluid is formed in an inner space of the first outer header,   a flow path for the first heat exchange pipe includes one end communicating with the inner space of the first inner header, and the other end communicating with the inner space of the first outer header,   a flow path for the second fluid is formed in the inner space of the second inner header,   the flow path of the second fluid is formed in the inner space of the second outer header, and   a flow path for the second heat exchange pipe includes one end communicating with the inner space of the second inner header, and the other end communicating with the inner space of the second outer header.   
     
     
         5 . The heat exchanger of  claim 3 , wherein the first fluid moves while drawing a spiral trajectory along the flow path for the first heat exchange pipe, and
 the second fluid moves while drawing a spiral trajectory parallel to the movement trajectory of the first fluid along the flow path for the second heat exchange pipe.   
     
     
         6 . The heat exchanger of  claim 3 , wherein the first inner header and the first outer header elongate in the same direction,
 the first heat exchange pipe comprises a plurality of first heat exchange pipes, each of the first heat exchange pipes including a first internal space forming the flow path for the first fluid and the first heat exchange pipes being sequentially arranged in a longitudinal direction of the first inner header,   the second inner header and the second outer header elongate in the longitudinal direction of the first inner header, and   the second heat exchange pipe comprises a plurality of second heat exchange pipes, each of the second heat exchange pipes including a second internal space forming the flow path for the second fluid and the second heat exchange pipes being sequentially arranged in a longitudinal direction of the second inner header.   
     
     
         7 . The heat exchanger of  claim 6 , wherein each of the plurality of second heat exchange pipes further comprises at least one partition plate configured to partition the second inner space into at least two spaces. 
     
     
         8 . The heat exchanger of  claim 3 , wherein the first heat exchange pipe comes in surface contact with the second heat exchange pipe. 
     
     
         9 . The heat exchanger of  claim 8 , wherein the first heat exchange pipe and the second heat exchange pipe comprise a metallic material having elasticity. 
     
     
         10 . The heat exchanger of  claim 8 , further comprising a thermal grease positioned between the first heat exchange pipe and the second heat exchange pipe.
