Tube Module of Radiator Core

Abstract

A radiator core includes a head tube and a tube module mounted on the head tube. The head tube is provided with multiple tube slots having multiple first sides and multiple second sides. The tube module includes multiple first tubes and multiple second tubes mounted in the tube slots. Each of the first tubes is provided with a first connecting portion having an increased thickness and resting on one of the first sides of the tube slots. Each of the second tubes is provided with a second connecting portion having an increased thickness and resting on one of the second sides of the tube slots.

1 . A radiator core comprising:
 an elongate hollow, generally cylinder; and   a tube module mounted on the elongate hollow, generally cylinder;   wherein:   the elongate hollow, generally cylinder is provided with a plurality of tube slots;   the tube slots of the head tube include a plurality of first sides and a plurality of second sides;   the tube module includes a plurality of first tubes and a plurality of second tubes;   the first tubes and the second tubes of the tube module are mounted in the tube slots;   each of the first tubes is a hollow tube formed integrally by bending a first sheet plate;   each of the first tubes has a first side provided with a first connecting portion and a second side provided with a first rim;   the first sheet plate has a stepped C-shaped arcuate first end and a C-shaped arcuate second end abutting the stepped C-shaped arcuate first end;   the stepped C-shaped arcuate first end and the C-shaped arcuate second end of the first sheet plate construct the first connecting portion of each of the first tubes;   the first connecting portion of each of the first tubes rests on one of the first sides of the tube slots;   each of the second tubes is a hollow tube formed integrally by bending a second sheet plate;   each of the second tubes has a first side provided with a second connecting portion and a second side provided with a second rim;   the second sheet plate has a stepped C-shaped arcuate first end and a C-shaped arcuate second end abutting the stepped C-shaped arcuate first end;   the stepped C-shaped arcuate first end and the C-shaped arcuate second end of the second sheet plate construct the second connecting portion of each of the second tubes;   the second connecting portion of each of the second tubes rests on one of the second sides of the tube slots; and   the second connecting portion of each of the second tubes is distant from the first connecting portion of each of the first tubes.   
     
     
         2 . The radiator core as claimed in  claim 1 , wherein the first tubes are arranged side by side on the first sides of the tube slots and form a first row, and the second tubes are arranged side by side on the second sides of the tube slots and form a second row. 
     
     
         3 . The radiator core as claimed in  claim 2 , wherein multiple rows of tubes are arranged side by side between the first row and the second row. 
     
     
         4 . (canceled) 
     
     
         5 . The radiator core as claimed in  claim 1 , wherein the first connecting portion of each of the first tubes forms a first reinforcement with two-layer wall thickness, and the second connecting portion of each of the second tubes forms a second reinforcement with two-layer wall thickness. 
     
     
         6 . The radiator core as claimed in  claim 1 , wherein the C-shaped arcuate second end of the first sheet plate is located outside of the stepped C-shaped arcuate first end. 
     
     
         7 . The radiator core as claimed in  claim 1 , wherein the C-shaped arcuate second end of the second sheet plate is located outside of the stepped C-shaped arcuate first end.
