Heat exchanger core, and method of assembling the heat exchanger core

Abstract

Reinforcement holes and tube holes are formed so as to be of the same size, and the interval between the reinforcement hole and the tube hole adjacent to the reinforcement hole is made equal to the interval between the adjacent tube holes.

1 . A method of assembling a heat exchanger core comprising steps of: 
 guiding fins along a horizontal guide surface formed in a base member;    guiding both ends of tubes and insertion sections of reinforcement member into tube guides which are provided on opposite sides of the base member while arranging alternately the fins and the tubes;    placing the reinforcement members at either end in the direction of arrangement of the fins and the tubes to thereby constitute a core section; and    attaching header members to opposite sides of the core section.    
   
   
       2 . A method of assembling a heat exchanger core according to  claim 1 , wherein a width of said reinforcement members is less than a width of said fins.  
   
   
       3 . A method of assembling a heat exchanger core according to  claim 1 , wherein a width of said insertion of said reinforcement member is substantially equal to a width of said tubes.  
   
   
       4 . A method of assembling a heat exchanger core comprising steps of: 
 guiding fins along a horizontal guide surface formed in a base member;    guiding both ends of tubes and insertion sections of reinforcement members into tube guides which are provided on opposite sides of the base member while arranging alternately the fins and the tubes;    placing the reinforcement members at either end in the direction of arrangement of the fins and the tubes to thereby constitute a core section; and    attaching header members to opposite sides of the core section,    wherein each of the reinforcement members is produced by procedures comprising: 
 forming a plurarlity of notches at regular intervals on a coil material formed from an aluminum clad by press working;  
 forming a joint section in each of the notches to be divided into a pair of the insertion sections;  
 forming a main body section on each side of the joint section to be formed into a reinforcing section;  
 forming a plurality of notches on opposite sides of a base end of the joint section;  
 forming a pair of notch grooves in each of opposite sides of a center portion of the joint section to be divided into a pair of chamfered sections;  
 cutting the coil material along a centerline running through the notch grooves; and  
 bending a longitudinal side edge of the main body section along the notches, to thereby form the reinforcing section.
