Abstract: A reinforcing connecting assembly is applied for a plurality of water pipes each of which includes a mouth portion defining an opening. The mouth portion includes a first curved portion. The reinforcing connecting assembly comprises a plurality of linking pieces and a connecting plate. Each of the linking pieces includes a connecting wall and two opposite side walls connected with the connecting wall. The connecting wall has a first surface abutting the first curved portion and a second surface opposite to the first surface. Each of the side walls includes a reinforcing portion. The reinforcing portions of the side walls are distant from each other and extend from two sides of the connecting wall toward a direction opposite to the first surface. The connecting plate connects the connecting wall of each of the linking pieces.

Abstract: A tube of a radiator includes a tube body, and a reinforcement strip. The tube body has a first curved face and a second curved face. The tube body is formed by a sheet plate which has two opposite ends connected to form a connecting portion which is located at the first curved face of the tube body. The reinforcement strip is mounted in the sheet plate and is located at the second curved face of the tube body. Thus, the first curved face of the tube body is formed with the connecting portion, and the second curved face of the tube body is combined with the reinforcement strip so that both of the first curved face and the second curved face of the tube body have a larger thickness to enhance the stiffness and strength of the tube body.
