In that case, a radiator is installed at the # end of the vehicle body facing forward, and the engine cooling water is circulated and cooled by the radiator. The radiator is mainly cooled by wind from driving, and a cooling fan may or may not be provided. The radiator is
Thin fins are provided all over the surface, allowing heat to be exchanged by allowing air to pass between them. Although the fins are thin so that there is less resistance to the air passing through, there is still some resistance. There are things where the wind escapes to the side. For this reason, some radiators have left and right sides bent forward to form upper and lower cylindrical parts to reduce the amount of air escaping to the left and right sides. For example, see Japanese Utility Model Application Publication No. 59-182629. However, even with this method, the radiator is installed along the down dup at the front end of the vehicle, resulting in an inclined installation with the bottom side of the radiator located at the rear, and the wind escaping mainly to the bottom side reduces cooling efficiency. ing.

る。This invention provides a motorcycle radiator that can reduce the amount of wind escaping to the bottom even if the radiator is mounted on the vehicle body at an angle, allowing maximum wind from driving to pass through the radiator, increasing cooling efficiency, and making it a small radiator. The purpose is to obtain.
以下、本発明を図面に示す実施例によって説明する。 Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings.

。The radiator 1 is made vertically and is fastened to the front side of the down tube 3 of the vehicle body 2 toward the front. Therefore, the radiator 1 is installed with a slight inclination so that the lower side is located at the rear side. It is then connected to the engine's cooling water jacket with a hose to circulate the engine's cooling water. Thus, the radiator 1 is provided with a number of thin pipes 4 for passing cooling water in the lateral direction, and fins 5 are provided between them.

に当るようにしである。The radiator 1 is horizontally curved 6 as a whole from the top to the bottom so that the center portion is located on the rear side in the left and right lateral directions. Further, in the vertical direction, the upper and central portions are flat surfaces, and the lower portion is vertically curved 7 so that the lower end is located on the front side. At the front of the vehicle body 2, there is a streamlined cowling 8.
is attached, and the radiator 1 is narrowed by 11 on the lower side so that it can be attached inside the cowling 8. A window hole 9 is provided in the cowling 8 on the front side of the radiator 1, and wind from driving passes through the window hole 9, and the radiator 1
This is so that it corresponds to

。When the motorcycle is run, wind from the run enters a window hole 9 provided in the front of the cowling 8 and hits the radiator 1. Radiator 1 is curved horizontally so that the center is concave toward the rear 6
Since the fins are vertical, there is some resistance to the wind passing between the fins 5, but the wind pressure at the center increases and the wind can be prevented from escaping to the left and right outside. In addition, the radiator 1 is installed with the lower side tilted toward the rear, and the wind that receives resistance tries to escape downward. Because there is a vertically curved part,
It acts as a dam and prevents wind from escaping to the bottom. In this way, almost all of the air that hits the radiator 1 can pass through the fins 5 and can be used for cooling, improving cooling efficiency and making the radiator 1 smaller. Further, by curving 6 the radiator 1 laterally, the exhaust air passing through the fins 5 is scattered in the left and right direction, thereby reducing the pressure. In addition, by similarly arranging the radiator 1 vertically, the wind can be dispersed to the lower side, and the wind that has passed through the radiator 1 can be
It can flow rearward along the inside of the cowling 8.

、軽量で製造コストも安（できる。(Effects of the Invention) As explained above, the present invention provides an engine cooling water radiator that is installed facing forward at the front end of a vehicle body, and is curved horizontally as a whole so that the center portion is located on the rear side in the left-right direction. In the vertical direction, the upper and center parts are flat, and the lower part is vertically curved so that the lower end is located on the front side. This prevents the wind from escaping to the image side and lower side of the radiator, and prevents the fins from escaping. Even if wind pressure increases due to resistance, more air can pass between the radiator fins and be used effectively for cooling, improving cooling efficiency. As a result, the radiator can be made smaller, lighter, and cheaper to manufacture.
