Can-type heat exchanger

Abstract

A can-type heat exchanger may include a housing of which one surface is opened and another surface is closed and having a space therein, and a first inlet and a first outlet, which communicate with the space, are provided in a lateral side thereof; a heat radiating unit inserted into the space, provided with connecting lines alternately formed by stacking a plurality of plates, one of the connecting lines communicating with the space, and where the operating fluids are heat-exchanged with each other while passing through the respective connecting lines; and a cover cap mounted at one opened surface of the housing so that the heat radiating unit is integrally mounted on one surface thereof to the space, and a second inlet and a second outlet for communicating with a second connecting line of the connecting lines, are formed at the one surface.

         3 . The can-type heat exchanger of  claim 2 , wherein
 the coupling portion is clinching-coupled to the housing on a state that an interior circumference thereof is surrounded by an exterior circumference of the housing.   
     
     
         4 . The can-type heat exchanger of  claim 1 , wherein
 a seal ring is disposed between the housing and the cover cap.   
     
     
         5 . The can-type heat exchanger of  claim 1 , wherein
 the first inlet and the first outlet are formed at separate locations at a lateral side of the housing.   
     
     
         6 . The can-type heat exchanger of  claim 1 , wherein
 the second inlet and the second outlet are formed at one surface of the cover cap to be spaced apart.   
     
     
         7 . The can-type heat exchanger of  claim 1 , wherein
 the first inlet and the first outlet are respectively formed at a position intersecting the second inlet and the second outlet.   
     
     
         8 . The can-type heat exchanger of  claim 1 , wherein
 the housing is formed with a cylinder shape through injection molding.   
     
     
         9 . The can-type heat exchanger of  claim 1 , wherein
 the housing is made of a plastic material.   
     
     
         10 . The can-type heat exchanger of  claim 1 , wherein
 the plate is formed with a disk shape, and first and second connecting holes are formed to the plate corresponding to the second inlet and the second outlet.   
     
     
         11 . The can-type heat exchanger of  claim 10 , wherein the heat radiating unit further comprises:
 a first fixing plate being mounted to a first surface of the heat radiating unit which is fixed to the cover cap and forming first and second penetration holes to correspond with the first and second connecting holes; and   a second fixing plate being mounted with a second surface of the heat radiating unit which is inserted into the space.   
     
     
         12 . The can-type heat exchanger of  claim 1 , wherein the plate comprises:
 a plurality of protrusions protruded from the plate to be disposed apart to each other by a set interval; and   a distributing protrusion formed from the center of the plate to an exterior circumference of the plate to be disposed between the first inlet and the first outlet.   
     
     
         13 . The can-type heat exchanger of  claim 12 , wherein
 the protrusions are formed with a hemisphere shape, and protrude from the plate in a same direction as the distributing protrusion.   
     
     
         14 . The can-type heat exchanger of  claim 1 , wherein
 one of operating fluids is a coolant flowing from a radiator, and another one of operating fluids is transmission oil flowing from an automatic transmission.   
     
     
         15 . The can-type heat exchanger of  claim 14 , wherein
 the coolant flows to the heat radiating unit through the first inlet and the first outlet, the transmission oil flows to the heat radiating unit through the second inlet and the second outlet, and   the connecting line comprises a first connecting line in which the coolant flows and a second connecting line in which the transmission oil flows.   
     
     
         16 . The can-type heat exchanger of  claim 1 , wherein
 at least one mounting portion is integrally formed with a second surface circumference of the housing.   
     
     
         17 . The can-type heat exchanger of  claim 1 , wherein
 the cover cap is made of a metal material, and the heat radiating unit is integrally mounted to the cover cap by brazing.
