Heat exchanger

Abstract

A heat exchanger comprises: a long and slender entrance side tank connected to one end side in the longitudinal direction of a plurality of laminated tubes; and an entrance pipe protruded from a wall face laid in the longitudinal direction of the entrance side tank, communicated with the inside of the entrance side tank, the heat exchanger further comprising: a division plate shifted from a center of a projected region which is formed when an inner diameter portion of the entrance pipe is projected into the entrance side tank, the division plate being formed into a plate-shape, the division plate being arranged so that the inside of the entrance side tank can be divided into two portions in the longitudinal direction and the plate face of the division plate can be laid in the axial direction of the entrance pipe, wherein the division plate divides a flow of fluid flowing into the entrance pipe by a plate-shaped end portion so that a flow of fluid flowing onto one side in the longitudinal direction of the entrance side tank and a flow of fluid flowing onto the other side in the longitudinal direction of the entrance side tank can be set at a predetermined ratio.

1 . A heat exchanger comprising: 
 a long and slender entrance side tank ( 120 ) connected to one end side in the longitudinal direction of a plurality of laminated tubes ( 111 ); and    an entrance pipe ( 121   a ) protruded from a wall face ( 121   d ) laid in the longitudinal direction of the entrance side tank ( 120 ), communicated with the inside of the entrance side tank ( 120 ),    the heat exchanger further comprising:    a division plate ( 123 ) shifted from a center of a projected region which is formed when an inner diameter portion of the entrance pipe ( 121   a ) is projected into the entrance side tank ( 120 ), the division plate ( 123 ) being formed into a plate-shape, the division plate ( 123 ) being arranged so that the inside of the entrance side tank ( 120 ) can be divided into two portions in the longitudinal direction and the plate face ( 123   a ) of the division plate ( 123 ) can be laid in the axial direction of the entrance pipe ( 121   a ), wherein    the division plate ( 123 ) divides a flow of fluid flowing into the entrance pipe ( 121   a ) by a plate-shaped end portion ( 123   b ) so that the flow rate of fluid flowing onto one side in the longitudinal direction of the entrance side tank ( 120 ) and the flow rate of fluid flowing onto the other side in the longitudinal direction of the entrance side tank ( 120 ) can be set at a predetermined ratio.    
   
   
       2 . A heat exchanger according to  claim 1 , wherein the entrance pipe ( 121   a ) is located on one side in the longitudinal direction of the entrance side tank ( 120 ), and 
 the division plate ( 123 ) is arranged at a position shifted by a predetermined distance to one side in the longitudinal direction of the entrance side tank ( 120 ).    
   
   
       3 . A heat exchanger according to  claim 1 , wherein the division plate ( 123 ) is extended into the entrance pipe ( 121   a ).
