It is an object of the present invention to prevent damage to the root of the outermost tube due to an external force or a thermal shock force and to provide a radiator having a durable core. [Structure] In a radiator having a core in which a tube is provided between seat plates of upper and lower tanks and fins are arranged between the adjacent tubes and between an outermost tube and a lane force, a reinforcing plate is fixed to a core side of the seat plate. Then, the end of the lane force was caulked and fixed by the end of the reinforcing plate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a radiator having a cooling core for cooling a heat engine engine such as an internal combustion engine mounted on an automobile.

[0002]

[Prior Art]

 As shown in FIG. 2, a conventional radiator having a core of this type has a large number of tubes in the upper and lower tanks 1 into which the cooling water of the engine is introduced, and in the seat plate 2 on the tube 3 side forming the same. 3 are caulked so as to communicate with each other in parallel and in the tank 1.

Fins 4 for increasing the cooling efficiency of the tubes 3 are provided on the outer surface of the tubes 3 so as to connect the tubes 3, and the outermost tubes 3 of the tubes 3 provided in parallel are provided. A lane force 5 is attached to the fins 4, and the lane force 5 is not connected to the seat plate 2 forming the tank 1 and thus is not fixed forcibly (for example, the actual opening). 62-175218).

Outside the lane force 5, supports 6 attached to the upper and lower surfaces of the upper and lower tanks 1 are attached, and the supports 6 are attached to a radiator attachment portion of the vehicle. is there.

[0005]

[Problems to be solved by the device]

 In the conventional radiator having this core, since the support 6 and the seat plate 2 forming the lower side of the tank 1 are integrated, when an external force or a thermal impact force is applied to this radiator, In particular, a large force is applied to the root of the outermost tube 3, and this portion is easily damaged, and there is a risk of lacking in durability.

The present invention solves the above-mentioned problems in the conventional radiator having such a core, and an external force or a thermal shock force is applied to the lane force so that the lane force is displaced and a force is applied to the root of the outermost tube. In this case, the applied force is reduced to prevent the tube root from being damaged, and the radiator has a durable core.

[0007]

[Means for Solving the Problems]

 The present invention is a radiator having a core provided with a tube between the seat plates of the upper and lower tanks and having fins arranged between the adjacent tubes and between the outermost tube and the lane force. It is characterized in that the plate is fixed and the end of the lane force is fixed by crimping at the end of the reinforcing plate.

[0008]

[Action]

 The radiator with the core of the present invention has the end of the reinforcement plate fixed to the seat plate, and the end of the lane force is caulked and fixed, so that the external force due to vibration and the thermal shock force are received by the lane force and the outermost part is used. It reduces these forces on the root of the tube.

[0009]

【Example】

 Next, an example of implementation of the present invention will be described below with reference to FIG. A seat plate 2 is provided below the upper tank 1 into which engine cooling water is introduced. The seat plate 2 is reinforced by fixing the reinforcing plate 7 to the lower side of the seat plate 2 by a method such as soldering after spot welding. The tube 3 through which the cooling water passes penetrates the reinforcing plate 7 and is caulked to the seat plate 2.

Further, although not shown, a reinforcing plate is similarly fixed to the upper seat plate forming the lower tank, and the tube 3 penetrating this is caulked to the seat plate. The fins 4 are provided on the outside of the tubes 3 so as to connect the tubes 2 to each other, as in the conventional case, but on the outside of the fins 4 provided on the outside of the outermost tube 3. The upper and lower ends of the attached lane force 5 are crimped to the reinforcing plate 7 so that the ends of the reinforcing plate 7 fixed to the seat plates 2 of the upper and lower tanks 1 are folded back. This crimped part is fixed by a method such as soldering.

As described above, since the reinforcement plate 7 for reinforcing the seat plate 2 forming the tank 1 and the lane force 5 are fixed, when the external force or the thermal shock force is applied, the lane force 5 and the tank 1 are also fixed. With this, it is possible to reduce the force applied to the base of the outermost tube 3 to the seat plate 2, which is a caulking portion.

In particular, when hot water on the engine side is introduced into the radiator, the lane force 5 also bears the force of pulling the tube 3 by thermal expansion, reducing the force applied to the base of the tube 3. To be done.

Therefore, by reducing these forces, the durability of the root of the outermost tube 3 which is most easily damaged is increased, water leakage from this portion can be eliminated, and the durability of the radiator can be improved. It will be improved.

[0014]

[Effect of the device]

 As described above, according to the present invention, the end of the lane force is fixed by crimping at the end of the reinforcing plate fixed to the seat plate, so the external force due to vibration and the thermal shock force are received by the lane force, and the outermost part is received. These forces at the base of the tube can be reduced.

Therefore, it is possible to prevent breakage of the root of the tube, which is the most easily broken part of the radiator, particularly the part where the outermost tube is attached to the seat plate, and water leakage does not occur at this part. It is possible to improve the reliability of the and improve its durability.
