Abstract

(57) [Summary] [Purpose] The objective is to improve the heat dissipation of the oil pan by a simple modification of the oil pan body structure. [Structure] Inside the oil pan main body 1, two ventilation pipes 2 having both ends open at both end walls of the oil pan main body 1 corresponding to the vehicle front-rear direction are provided so as to extend parallel to each other and parallel to the bottom surface of the oil pan main body 1. As a result, the heat dissipation area itself of the oil pan main body 1 can be increased, and the wind passing through the ventilation pipe 2 cools the oil pan main body 1 not only from the outside but also from the inside, so that the lubricating oil in the inside can be efficiently used. It is cooled and the rise in oil temperature can be effectively suppressed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an oil pan for an internal combustion engine for a vehicle, and more particularly to a technique for improving heat dissipation of the oil pan.

[0002]

[Prior art]

 In recent years, as the output of internal combustion engines for vehicles has increased, the temperature of the lubricating oil in the engine has tended to rise, and various lubricating oil cooling measures have been adopted. For example, conventionally, as a cooling device for lubricating oil, there is an oil cooler. As a measure for improving the heat dissipation of lubricating oil, there is an oil pan body made of aluminum that is used to improve the heat dissipation from the oil pan. A vehicle compartment is provided to make effective use of the van body's space.

As an oil pan technology, there is one disclosed in Japanese Utility Model Laid-Open No. 64-46454.

[0004]

[Problems to be solved by the device]

 By the way, even if the conventional oil cooler is used, if the performance of the oil cooler is improved, there is a problem that the cost is increased. Further, when the aluminum oil pan body is applied, the manufacturing cost is higher than that of the press-molded product.

In view of the conventional situation as described above, the present invention aims to improve the heat dissipation of the oil pan by simply improving the structure of the oil pan body.

[0006]

[Means for Solving the Problems]

 For this reason, in the present invention, ventilation pipes having both ends open are provided inside the oil pan body on both end walls of the oil pan body corresponding to the vehicle longitudinal direction.

[0007]

[Action]

 In this configuration, by providing the ventilation pipe in the oil pan body, the heat radiation area of the oil pan body can be increased, and the lubricating oil can be efficiently cooled by the air passing through the ventilation pipe to increase the temperature of the lubricating oil. It can be effectively suppressed, and it is also cost effective.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, inside the oil pan body 1, two ventilation pipes 2 having both ends open to both end walls of the oil pan body 1 corresponding to the vehicle front-rear direction extend parallel to each other and parallel to the bottom surface of the oil pan body 1. Is provided.

Both ends of the ventilation pipe 2 are fixed by welding to mounting holes 3 respectively formed in both end walls of the oil pan body 1. In such a configuration, the wind or the running wind by the cooling fan that hits the front surface of the oil pan body 1 flows backward along the outer wall of the oil pan body 1, and the oil pan body 1 is cooled from the outside. By providing the ventilation pipe 2 extending along the direction, the wind or the traveling wind by the cooling fan flows in the ventilation pipe 2, and the oil pan body 1 is also cooled from the inside.

By providing the ventilation pipe 2 in the oil pan main body 1 in this way, the heat dissipation area itself of the oil pan main body 1 can be increased, and the wind passing through the ventilation pipe 2 allows the oil pan main body 1 to move to the outside. The internal lubricating oil is cooled efficiently not only from the internal side but also from the internal side, and the oil temperature rise can be effectively suppressed. As a result, it is possible to suppress an increase in the temperature of the lubricating oil, to improve the performance of the engine, to prevent the deterioration of the lubricating oil, and to improve the life of the lubricating oil.

Further, since the ventilation pipe 2 is simply provided in the oil pan body 1, it is cost effective. Although two ventilation pipes 2 are provided in the above-described embodiment, a plurality of ventilation pipes 2 may be provided, such as 3, 4, ... As described above, the present invention has been described with reference to the specific embodiments. However, the present invention is not limited to this, and a person skilled in the art can register the utility model attached to the present invention. It should be noted that various changes and modifications can be made without departing from the scope of the claims.

[Effect of device]

 As described above, according to the oil pan of the internal combustion engine for a vehicle of the present invention, the ventilation pipes having both ends opened are provided inside the oil pan body at both end walls corresponding to the vehicle front-rear direction. The heat dissipation area of the oil pan body can be increased, and the lubricating oil can be efficiently cooled by the air passing through the ventilation pipe, which effectively suppresses the temperature rise of the lubricating oil, which is also advantageous in terms of cost. This is a great practical effect with the advantage.
