【発明が解決しようとする課題】しかし、エンジン収納
部にあるエンジンは、冷却ファンにより冷却されるが、
隣接するタンク収納部は、エンジンの排熱とそれ自体高
温になる作動油タンクとにより熱がこもるため、作動油
及び燃料の温度が高くなることに起因する機能低下をま
ねきやすい。また、高温化による不具合を防止するため
にタンク収納部に冷却ファンを取り付ける冷却手段も考
えられるが、コンパクトに配置してあるので特別に冷却
ファンを設けるスペースを確保することが困難であり、
かつ、コストも高くなる。However, although the engine in the engine housing is cooled by the cooling fan,
Adjacent tank housings retain heat due to the exhaust heat of the engine and the hydraulic oil tank which itself becomes high in temperature, so that it is easy to cause functional deterioration due to the temperature of hydraulic oil and fuel increasing. In addition, a cooling means for attaching a cooling fan to the tank storage part in order to prevent problems due to high temperature can be considered, but it is difficult to secure a space for installing a cooling fan because it is arranged compactly.
At the same time, the cost is high.
【0004】本発明の目的は、簡単な構造で合理的にエ
ンジンの冷却排風を利用し、安価に、かつ、大型化をま
ねくことなく作動油タンク及び燃料タンクを冷却する点
にある。An object of the present invention is to cool the hydraulic oil tank and the fuel tank at a low cost and without increasing the size of the engine, by utilizing the cooling exhaust air of the engine reasonably with a simple structure.
【0005】[0005]
【課題を解決するための手段】前記エンジン収納部にエ
ンジンの冷却排風の一部をタンク収納部に導く制風板を

冷却排風に対して上手側となるように配置したことにあ
る。A wind control plate for guiding a part of engine cooling exhaust air to a tank housing portion is provided in the engine housing portion, and a hydraulic oil tank of the tank housing portion serves as engine cooling exhaust air. On the other hand, it is arranged so that it is on the better side.

ク収納部に導かれた一部の冷却排風により、前記冷却排
風よりも高温である作動油タンクが冷却されるので作動
油タンクの放熱による下手側にある燃料タンクの温度上
昇も抑制される。In other words, a wind control plate is provided in the engine storage portion, and a part of the cooling exhaust air guided to the tank storage portion cools the hydraulic oil tank having a temperature higher than that of the cooling exhaust air. Also, the temperature rise of the fuel tank on the lower side due to the heat radiation is suppressed.

できるに到った。As a result, the cooling exhaust air of the engine can be effectively utilized with a simple structure in which only the wind control plate is attached to the engine storage portion, so that it is not necessary to provide a cooling fan in the tank storage portion, and the cost is low. The present invention has made it possible to provide a hydraulic oil tank and a fuel tank that can be cooled without increasing the size of the hydraulic oil and can prevent functional deterioration due to high temperatures of the hydraulic oil and the fuel.

を抑制することができる。As shown in FIG. 3, the cooling fan 10 provided in the engine housing 12 takes in the outside air for cooling the engine 11 from the outside air intake 9a of the bonnet 9 and cools the engine 11. Then, the cooling exhaust air of the engine 11 after cooling the engine 11 flows out from the lower part of the swivel base 3 to the outside, and a part thereof is guided to the tank storage portion 15 by the wind control plate 16 provided in the engine storage portion 12. Then, it is used as a cooling wind for the hydraulic oil 13 and the fuel tank 14, and flows out from the lower part of the swivel base 3. At this time, the operating oil tank 13 in operation is at a higher temperature than the cooling exhaust air of the engine 11, so the cooling exhaust air guided to the tank housing portion 15 is used as cooling air for cooling the operating oil tank 13. ,
It is possible to cool the hydraulic oil tank 13 and suppress a temperature rise due to heat radiation of the hydraulic oil tank 13 of the fuel tank 14 on the lower side.
