ーヘッドを冷却するようにしである。冷却が十分行われ
るには、大型の冷却ファンで、多量の送風をする必要が
あるが、冷却ファンを大型にすると、駆動力も大きくな
シ、エンジンの出力損失が増す。従って、成るべく小さ

ンを冷却する必要がある。Forced air-cooled engines have a large number of cooling fins on the engine's cylinder and cylinder head, cover the cylinder and cylinder head with a cooling cowl, and force air generated by a cooling fan connected or linked to the crankshaft into the cooling cowl. Air is blown to cool the cylinder and cylinder head. In order to achieve sufficient cooling, it is necessary to use a large cooling fan to blow a large amount of air, but the larger the cooling fan, the greater the driving force, which increases engine output loss. Therefore, it is necessary to use a cooling fan as small as possible to reduce output loss and efficiently cool the engine.

の冷却装置を得ることを目的とする。In view of this, an object of the present invention is to provide an engine cooling device that uses a heat sink and a heat pipe and can be efficiently cooled with a small cooling fan.
以下、本発明を図面に示す実施例について説明する。 Embodiments of the present invention shown in the drawings will be described below.

。A large number of cooling fins 3 are erected on the cylinder 1 and the cylinder head 2 in accordance with the air blowing direction. Cylinder 1. The cylinder head 2 is covered with a cooling cowl 4, cooling air is forcedly blown from one side of the cooling cowl 4 by a cooling fan, and the air after cooling is exhausted from an air exhaust port 5. The cooling cowl 4 has one side cut out to form a window hole 8,
A heat dissipation plate 6 made of a light alloy or the like with good thermal conductivity and having a large number of cooling fins 7 on its inner and outer surfaces is attached so as to close this window hole 8. Then, the other end of the heat pipe IO connected to the vicinity of the exhaust hole 9 where the temperature of the cylinder 1 becomes high is connected to the heat sink plate 6.
しかして、シリンダー１及びシリンダーヘッド２は、通
常の強制空冷エンジンのように、冷却カウル４内に強制
送風される冷却風が冷却フィン３に当って冷却される。Thus, the cylinder 1 and the cylinder head 2 are cooled by the cooling air forced into the cooling cowl 4 hitting the cooling fins 3, like in a normal forced air-cooled engine.

る。In addition, the temperature of the high temperature part of the cylinder 1 is transferred to the heat sink 6 through the heat pipe 0,
The inner side is cooled by the forced cooling air in the cooling cowl 4, and the outer side is cooled by the atmosphere. In this way, extra cooling can be achieved by the amount of cooling provided by the heat sink 6, and a small cooling fan with low output loss can be used.

、冷却風は少量でよく、冷却ファンの小型化ができ、出
力損失も少くできて、効果的に冷却ができる。As explained above, the present invention provides a cylinder and a cylinder head with a large number of cooling fins, and covers the cylinder with a cooling cowl to forcefully blow cooling air into the cooling cowl. The window hole is covered with a heat sink with cooling fins on the inner and outer surfaces, and the heat sink and cylinder are connected with a heat pipe, so the inner surface of the heat sink is cooled by forced cooling air and the outer surface is cooled by the atmosphere. , the cylinder can be cooled extra by the amount that can be cooled by the heat sink. Therefore, only a small amount of cooling air is required, the cooling fan can be made smaller, output loss can be reduced, and cooling can be performed effectively.
