Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a front body structure of an automobile related to cooling a radiator.

(Prior art) Conventionally, Japanese Patent Application Laid-Open No. 126621 (1982) has been used as a front body structure of an automobile related to cooling an engine radiator.
The one disclosed in the publication No. 1 is known. The device disclosed in Japanese Patent Application Laid-open No. 51-126621 has a wind guide plate installed in the air introduction passage communicating with the air intake provided at the lower front of the vehicle body to minimize turbulence. The air flowing into the air intake is rectified by the baffle plate and guided to the radiator, increasing the cooling efficiency of the radiator. By the way, recently, air-cooled intercoolers,
As water-cooled intercoolers and the like are being installed in vehicles, there is a growing demand for a dedicated sub-radiator to be installed in air-cooled intercoolers and the like, separate from the engine radiator. However, in this conventional structure, when a sub-radiator is installed in the air introduction passageway of the radiator for the engine in parallel with the radiator for the engine, the presence of the radiator on the upstream side causes The wind blows against the radiator installed downstream, and
There is a problem in that the cooling efficiency of the radiator provided on the downstream side is affected.

By the way, from the viewpoint of increasing cooling efficiency, it is desirable to apply air to each radiator separately, but it is desirable to install a sub-radiator in the air introduction passage of the engine radiator in parallel with the engine radiator, and For example, as a structure that minimizes the loss of cooling efficiency of the radiator installed on the downstream side,
Publication No. 53618 states that among radiators installed one after the other in the longitudinal direction of the vehicle body in the air introduction passage of an engine radiator, the radiator installed on the downstream side is set higher than the radiator installed on the upstream side. A vehicle has been disclosed in which a part of the vehicle body is protruded in the width direction, and the wind is directed directly to the protruding part of a radiator installed downstream of the radiator.
-The device disclosed in Publication No. 53618 has a configuration in which the radiator installed on the downstream side extends long in the width direction of the vehicle body, ensuring a large installation space for the radiator in the width direction of the vehicle body. In automobiles, it is difficult to effectively secure installation space for successive radiators due to constraints on the installation space of radiators, and in areas where successive radiators overlap in the width direction of the car body, it is difficult to effectively secure installation space for successive radiators. The problem is that it is difficult to increase the cooling efficiency of the radiator on the downstream side.

(Purpose of the invention) The present invention was made in view of the problems of the above-mentioned prior art, and its purpose is to be able to install radiators one after the other without impairing the cooling efficiency as much as possible. Another object of the present invention is to provide a front body structure for an automobile, which can effectively secure a space for installing a radiator even in a small automobile, and improves the cooling efficiency of both radiators.

A baffle plate is provided which distributes and guides the air flowing in from the air intake port to the two chambers, and the baffle plate becomes convex downward as it goes from the front to the rear. The lower rear chamber is provided with a main radiator, the upper front chamber is provided with a sub-radiator smaller than the main radiator, and each of these radiators has a shape that curves upward. It is configured such that it is tilted forward so as to be substantially orthogonal to the flow direction of the air guided by the wind plate.
