あつた。 As shown in FIG. 1, the cooling water circuit of a diesel locomotive is comprised of two systems, the engine 6 having a main circuit a that cools around the cylinders of the engine and a subcircuit b that cools the engine oil. For this reason, the radiators 1 and 2 are disposed in the longitudinal direction of the vehicle body for use in the main circuit and for the sub-circuit, so that the radiators become longer in the longitudinal direction of the vehicle body, resulting in an increase in the length of the vehicle body.

接続されている（第２図）。 An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. A double-arranged main circuit radiator group 1 and sub-circuit radiator group 2 are installed in openings provided on both sides of the car body 4 of the diesel locomotive, and are connected by a radiator fan 5 provided at the top of the car body 4. Cooling air is sucked in from the sides of the vehicle, passed through both radiator groups, and exhausted from the top.
The main circuit radiator group 1 and the sub circuit radiator group 2 are a plurality of radiator units each having upper and lower water tanks 1a and 2a, respectively.
a are arranged linearly adjacent to each other in plan view and supported by a common frame 3. For this reason,
The main circuit radiator group 1 and the sub circuit radiator group 2 are arranged one on the other. and,
The frame body 3 is configured to surround each radiator group, and two frame bodies 3 are attached to the side surface of the vehicle body 4. When this frame body 3 is attached, it is attached so that the main circuit radiator group 1 is on the leeward side. On the other hand, the upper and lower water tanks 1a of each radiator unit of the main circuit radiator group 1 on the leeward side are cut out at the corners to provide a relief part C, and each radiator unit of the sub circuit radiator group arranged on the back side The pipes 2b connected to the upper and lower water tanks 2a are pulled out. Naturally, pipes 1b are also drawn out from each water tank 1a on the main circuit radiator group 1 side. The pipes 1b and 2b are connected to a main circuit a for cooling the cylinders of the engine 6, and to a subcircuit b for cooling engine oil (FIG. 2).
冷却風は矢印で示すように、ラジエータフアン
５の吸入風で、副回路ラジエータ２を冷却しさら
に主回路ラジエータ１を通つてラジエータフアン
５で外部に吐出される。 As shown by the arrow, the cooling air is sucked into the radiator fan 5 and cools the auxiliary circuit radiator 2, and then passes through the main circuit radiator 1 and is discharged to the outside by the radiator fan 5.
副回路ｂの冷却水の温度はオイル等を冷却する
ものであるから68℃と低く、主回路ａの冷却水温
度はエンジンｂを冷却するため85℃高温である。 The temperature of the cooling water in the subcircuit b is low at 68°C because it cools oil and the like, and the temperature of the cooling water in the main circuit a is high at 85°C because it cools the engine b.
従つて副回路を通過後の空気温の上昇は約10℃
しか上らないため、高温である主回路ａの冷却に
も十分利用できる。 Therefore, the increase in air temperature after passing through the subcircuit is approximately 10℃.
Since only a small amount of heat rises, it can be sufficiently utilized for cooling the main circuit a, which is at a high temperature.

面に合せて設置でき、この点においてもラジエー
タ設置面積を減らすことになる。 As described above, each radiator group 1, 2 is arranged front and back by the frame 3, and the pipe 2b from the water tank 2a of the radiator group on the back side when viewed from the vehicle body is connected to the water tank 1a of the front side radiator group. Since it is constructed so that it can be pulled out to the inside of the vehicle body from the provided relief part C, the radiator installation area can be approximately halved compared to the conventional case where each radiator group was attached to the side of the vehicle body. Since all the radiator groups 1 and 2 are supported by the frame 3, there is an advantage that it can be easily attached to the side of the vehicle body. Furthermore, since the pipe 2b from the water tank of the sub-circuit radiator group 2 is drawn out to the inside of the vehicle, there is no need for piping space between the sub-circuit radiator 2 and the side of the vehicle, and the radiator can be installed along the side of the vehicle. This also reduces the installation area of the radiator.

通風路形状が狭くなり、ラジエータ冷却効率を低
下させることになる。尚、内側に引出されたパイ
プ１ｂ，２ｂは通風路を狭くするほど多く配管さ
れるものではないので冷却効率の低下はない。 It is also possible to draw out the pipes 1b and 2b from the water tank in a direction along the longitudinal direction of the vehicle body.
The presence of adjacent radiator units and frames in that direction may make pulling out the drawer cumbersome or impossible. Also, if the water tank pipe on the back side is pulled out from the back side, the space for the drawer must be secured, so the entire radiator will be located inside the side of the car body by the amount of the drawer space, which is the opposite. Since the facing distance from the radiator placed on the side of the car body becomes narrower,
The shape of the ventilation passage becomes narrow, reducing the radiator cooling efficiency. Note that the number of pipes 1b and 2b drawn inward is not so large as to narrow the ventilation passage, so there is no reduction in cooling efficiency.
そのためラジエータの設置面積を縮少する（逆

ラジエータ群を表裏一体に重ねて設けるだけでな

イプ引出しを車体内側へ引出するようにしなけれ
ば効果がない。 Therefore, in order to reduce the installation area of the radiators (or conversely, to make the shape of the ventilation passage more spacious without increasing the size of the car body), each radiator group should be integrated into the front and back sides using a common frame. In addition to overlapping the pipes, the pipes from the water tanks of the radiator group on the back side must also be drawn out to the inside of the vehicle to be effective.
上記構成を適用したことにより、従来の冷却装
置より長さを約30％つめることができ車体長さが

で冷却できた。 By applying the above configuration, the length of the cooling system can be reduced by approximately 30% compared to the conventional cooling system, making it possible to shorten the vehicle body length.Also, because the length of the cooling system is shortened, even a 200 horsepower class engine can only use one radiator fan. I was able to cool it down.
