Abstract

(57) [Abstract] [Purpose] The objective is to achieve weight reduction and vibration durability, reduce manufacturing costs, improve cooling performance, and make it suitable for large trucks. [Structure] In a vehicle radiator in which a tube is provided between tanks and a radiation fin is provided on the outer circumference of the tube, the tube and the radiation fin are integrally formed of an aluminum material.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle radiator.

[0002]

[Prior Art]

 Generally, in a vehicle radiator, a tube is provided between upper and lower tanks and a heat radiation fin is provided on the outer circumference of the tube (for example, Japanese Utility Model Laid-Open No. 62-175218).

In the truck radiator, the tube and the radiation fin are made of brass, and the brass radiation fin is brazed to the brass tube.

[0004]

[Problems to be solved by the device]

 However, the radiator using the brass tube and the brass radiating fin has a problem that it is very heavy.

Therefore, in passenger cars, there is a radiator in which the tubes and the radiation fins are made of aluminum. However, although aluminum radiators can be made lighter in weight, they have lower strength than brass radiators, so they are inferior in vibration durability and have a short service life, making them unsuitable for large truck radiators.

The present invention has been made in order to solve the above drawbacks, and provides a vehicle radiator suitable for a heavy-duty truck, which is lighter in weight, more durable against vibrations, lower in manufacturing cost, and improved in cooling effect. With the goal.

[0007]

Means for Solving the Problems The present invention relates to a vehicle radiator in which a tube is provided between tanks and a radiation fin is provided on the outer circumference of the tube, and the tube and the radiation fin are integrally formed of an aluminum material. It is characterized by

[0008]

[Action]

 If the tube and radiating fins are made of an integrally molded aluminum material, the weight will be lighter, brazing will not be required, and the two will be joined securely and the vibration durability will be improved.

Further, by integrally molding, the manufacturing cost is reduced, the heat dissipation is improved, and the cooling performance is improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a radiator for a vehicle according to the present invention, in which 1 is an upper tank of a radiator and 2 is a lower tank. Reference numeral 3 denotes a tube provided between the upper tank 1 and the lower tank 2, and 4 denotes a heat radiation fin provided on the outer circumference of the tube 3 along the tube axial direction.

The tube 3 and the radiating fin 4 are made of an aluminum material, and are integrally formed as shown in FIG. The tube 3 and the radiation fin 4 are integrally molded by, for example, an extrusion molding method. In addition, 5 is a reinforcement provided on the left and right of the radiator for reinforcement.

According to such a vehicle radiator, since the tube 3 and the radiation fin 4 are made of an integrally molded aluminum material, the weight can be reduced. Further, since the tube 3 and the radiation fin 4 are securely joined together, the vibration durability is improved and the heat dissipation is improved, and the cooling performance is improved.

Further, since the tube 3 and the radiation fin 4 are integrally molded, they are manufactured at the same time and the manufacturing cost is reduced. The vehicle radiator of the present invention is suitable for a large truck radiator, but is also suitable for a passenger vehicle radiator and other vehicle radiators.

[0014]

[Effect of the device]

 As described above, according to the present invention, it is possible to reduce the weight, improve the vibration durability and the cooling performance, and reduce the manufacturing cost.
