Benefits of technology

【0012】 (1)に記載の作業機用のラジエータによれば、このラジエータが大きく傾斜した場合に、冷却液の液面が一方の注水管の途中まで到達することがあっても、アッパータンクの上方に配置された冷却液供給部の設置部に到達することがなく、冷却液供給部に接続されたオーバーフローホース等を介してラジエータリザーブタンク内に冷却液が流出することが防止される。したがって、作業機用のラジエータ内に収容された冷却液の水量が不足した状態となることに起因したエンジンのオーバーヒートを効果的に防止できるという利点がある。

Abstract

To provide a radiator for a work machine whereby: even when a work machine is operated on steep slopes, it is possible to effectively prevent the radiator mounted on the work machine from overheating, and also provide a work machine for slopes.SOLUTION: A radiator for a work machine includes: a radiator body 3 having an upper tank 2 at its top; a pair of water injection pipes 5, 5 that extend upwards from both left and right ends of the upper tank 2; a confluence part 6 where the pair of water injection pipes 5, 5 meet; a coolant supplier 7 at the top of the confluence part 6; a radiator cap 8 that closes the top opening of the coolant supplier 7 in an openable manner; and a radiator subtank 11 that is connected to the coolant supplier 7 through an overflow hose 9.SELECTED DRAWING: Figure 1

Claims

1. The radiator body has an upper tank located at the top, A pair of water inlet pipes extending upward from both the left and right ends of the upper tank, The junction where the pair of water inlet pipes meet, A coolant supply unit is provided at the upper part of the aforementioned confluence section, A radiator cap that can open and close the upper end opening of the coolant supply section, The coolant supply section is connected to a radiator sub-tank via an overflow hose, The pair of water inlet pipes and the junction are formed by bending a single pipe member, creating a radiator for a work machine.

2. The water supply pipe has a lower portion that extends upward from the upper surface of the upper tank, A radiator for a work machine according to claim 1, having an inclined portion extending from the upper end of the lower portion toward the confluence portion.

3. The radiator for a work machine according to claim 2, wherein the merging portion is arranged on a center line passing through the center of the widthwise portion of the radiator body.

4. A radiator for a work machine, as described in any one of Claims 1 to 3, which is mounted on a work machine used on a slope.

5. A work machine for slopes equipped with a radiator having a radiator body with an upper tank located at the top, A pair of water inlet pipes extending upward from both the left and right ends of the upper tank, The junction where the pair of water inlet pipes meet, A coolant supply unit is provided at the upper part of the aforementioned confluence section, A cap that can open and close the upper end opening of the coolant supply section, The coolant supply section is connected to a radiator sub-tank via an overflow hose, A work machine for slopes, wherein the pair of water inlet pipes and the junction are formed by bending a single pipe member.
