Heat exchanger

Abstract

A heat exchanger including a tube unit in which a plurality of tubes ( 2 ) which are disposed in a stacked state, a one side header tank part ( 4 ) which is provided at one end side of the tube unit and in which a returning tank chamber ( 12 ) is formed, an other side header tank part ( 5 ) which is provided at other end side of the tube unit and in which an inlet tank chamber ( 14 ) and an outlet tank chamber ( 15 ) are formed, an inlet pipe connecting part ( 18 ) and an outlet pipe connecting part ( 19 ) which are provided on the other side header tank part ( 5 ), inclined sections ( 16 ) and ( 17 ) configured to incline to a longitudinal direction of the tubes ( 2 ) being provided at two locations on the other side header tank part ( 5 ), the inlet pipe connecting part ( 18 ) and the outlet pipe connecting part ( 19 ) being provided on the inclined sections ( 16 ) and ( 17 ), respectively.

1 . A heat exchanger, comprising: 
 a tube unit in which a plurality of tubes are disposed in a stacked state;    a one side header tank part which is provided at one end side of the tube unit and in which a returning tank chamber is formed;    an other side header tank part which is provided at other end side of the tube unit and in which an inlet tank chamber and an outlet tank chamber are disposed adjacently in a stacked direction of the tubes;    an inlet pipe connecting part provided on the other side header tank part and configured to guide fluid from an outside into the inlet tank chamber; and    an outlet pipe connecting part provided on the other side header tank part and configured to discharge the fluid to an outside of the outlet tank chamber,    wherein inclined sections configured to incline to a longitudinal direction of the tubes are provided at two locations on the other side header tank part,    wherein the inlet pipe connecting part and the outlet pipe connecting part are provided on the inclined sections, respectively.    
     
     
         2 . The heat exchanger according to  claim 1 , 
 wherein the inclined sections are inclined in a similar direction to each other.    
     
     
         3 . The heat exchanger according to  claim 1 , 
 wherein the inclined sections are inclined at a substantially similar angle to each other.    
     
     
         4 . The heat exchanger according to  claim 1 , 
 wherein if the number of the tubes which communicate with the inlet tank chamber and are outward flow paths is B 1  and the number of the tubes which communicate with the outlet tank chamber and are homeward flow paths is B 2 , a relation between By and B 2  is set to be B 1 >B 2 .
