And a plurality of inertial separation filter mounting holes 50c. The inertial separation filter 9 is a filter through the

packings

19a and 19b in a state where the cooling air blower 9a and the exhaust air blower 9b respectively face the cooling air blower 50a and the exhaust air blower 50b of the filter mounting plate 50. It is mounted on the mounting plate 50. As a result, the cooling air vent 9a of the inertial separation filter 9 is airtightly connected to the cooling air vent 50a of the filter mounting plate 50 via the packing 19a, and the discharge air vent 50b of the filter mounting plate 50 is The exhaust air blowing port 9b of the inertial separation filter 9 is airtightly connected via the packing 19b. The inertial separation filter 9 and the filter mounting plate 50 can be fixed by bolts or the like passing through the fixing hole 9 c of the inertial separation filter and the mounting hole 50 c of the mounting plate 50.

As shown in FIG. 1, the cooling air blowing port 50 a of the filter mounting plate 50 is in communication with the air passage area 5 b on the downstream side of the removal air passage 5, and further, the cooling air passage 7 at the downstream end of the removal air passage 5. One end of is connected. The cooling air passage 7 penetrates the floor plate 48 and extends in the vertical direction, and the other end is connected to the main motor 23 as a device to be cooled. As a result, the cooling air passage 7 guides the cooling air from which dust has been removed by the inertial separation filter 9 to the main motor 23.

One end of the discharge air passage 8 is connected to the discharge air blowing port 50 b of the filter mounting plate 50. The exhaust air passage 8 penetrates the removal air passage 5 and the floor plate 48 and extends to the outside of the vehicle body 1. Then, the exhaust air passage 8 discharges the outside air including the dust removed by the inertial separation filter 9 to the outside of the vehicle body 1.

As shown in FIG. 1, an inspection port 10 is formed in the removal air passage 5, and the inspection port 10 is opened in the vehicle main body 46, that is, opened in the passage 15 side.

By opening the door 13, maintenance work such as replacement, repair, and cleaning of the inertial separation filter 9 can be performed from the inside of the vehicle body 46 through the inspection opening 10.

Further, a pressure outlet 14 is formed in the removal air passage 5 and is opened in the vehicle main body 46, and is in communication with the air passage region 5b on the downstream side of the removal air passage.

According to the cooling device 20 configured as described above, when the blower 6 is driven, outside air is taken in from the intake port 11 and flows into the blower 6 through the intake air passage 4. The outside air flowing into the blower 6 is sent into the removal air passage 5 by the blowing action of the blower 6.

Outside air flowing into the removal air passage 5 flows from the intake port of the inertial separation filter 9 into the inertial separation filter, enters a tube connected to the intake port, and rotates in a spiral in the tube. The inertial separation filter 9 removes dust contained in the outside air by centrifugal force generated during rotation, and collects it outside the inertial separation filter 9. Outside air containing a large amount of collected dust is discharged to the outside of the vehicle body 1 through the discharge air passage 8. On the other hand, the cooling air separated from dust in the inertial separation filter 9 and containing almost no dust passes through the cooling air passage 7 and is blown to the main motor 23 that needs to be cooled to cool it.

When the cooling air passage 7 receives air pressure from the blower 6, it separates from dust in the inertial separation filter 9, and a part of the cooling air containing almost no dust is discharged from the pressurized air outlet 14 into the vehicle body 1. As a result, pressure is applied to the inside of the vehicle body 1 to prevent the inflow of dust from the outside of the vehicle, and ventilation for discharging the heat generated from the main conversion device 16 installed in the vehicle main body 46 and other electric devices to the outside of the vehicle. Can play the role of

In the present embodiment, the removal air passage 5 can be completely independent of the side wall 47 forming the side surface of the vehicle, and when assembling the vehicle body 1 into a can, the outer plate is made of steel beforehand by welding or the like. It is only necessary to stand the panel of the side wall 47 attached to the body on the upper part of the chassis frame 3. That is, there is no need to weld the vehicle body outer plate and the removal air passage 5, and individual can-making can be performed. Although there is a method using a sealing agent instead of welding, a working space necessary for the sealing operation must be secured around the removal air passage 5. In the cooling device 20 according to the present embodiment, no alignment work or sealing work is required.

In the cooling device 20, by separating the connection positions of the intake port 11, the intake air duct 4 and the blower 6 as much as possible in the vehicle main body 36, it is possible to avoid a right-angled structure that makes assembly difficult. The cooling device 20 is assembled on the side of the vehicle opposite to the side of the vehicle where the intake port 11 is provided, so that the connection of the intake air passage 4, the blower 6 and the removal air passage 5 is a vertical structure along the vertical direction. It can be assembled as a body. Therefore, even if there is an error or eccentricity in verticality or flatness, the elastic good packing 17 provided between the upper part of the fan 6 and the intake air passage 4 on the roof side and the

flanges

4a, 26a absorb the error. Airtightness and watertightness can be ensured. The blower 6 is attached in advance to the upper part of the removal air passage 5, and the ceiling wall 30 incorporating the intake air passage 4 integrally is covered with the ceiling wall 30 to complete the assembling work of the vehicle body 1.

Since the intake port 11 is provided in the ceiling wall 30 and the exhaust air passage 8 is not provided in the side surface of the vehicle body 1, there is no need to process the opening in the outer plate of the vehicle body 1. Since the vehicle body 1 does not have the opening, manufacture of the vehicle body 1 is facilitated, and corrosion of the inside of the vehicle body due to dust and the like from the outside can be prevented.

Further, the inspection port 10 provided on the passage 15 side of the space in the vehicle main body 46, that is, the machine room for setting the electric device, is made sufficiently larger than the inertial separation filter 9 so that the passage 15 side. It is possible to easily incorporate the inertial separation filter 9 from the above. Remove the inertia separation filter 9 from the inspection port 10 into the air passage 5, insert the tip into the positioning bracket, and use a bolt etc. in the fixing hole 9c provided around the inertia separation filter 9 Tighten to 50. By providing the

packings

19a and 19b around the cooling air vents 50a and the exhaust air vents 50b of the filter mounting plate 50, air tightness and water tightness can be secured by simply tightening the filter fixing screws. As shown in FIGS. 2A and 2B, the cooling air vent 9a of the inertial separation filter 9 is connected to the cooling air vent 50a of the filter mounting plate 50 via the packing 19a, and the exhaust air vent 50b of the mounting plate 50. The discharge air blowing port 9b of the inertial separation filter 9 is connected via the packing 19b. Therefore, a very high sealing property is realized at the connection portion of the inertial separation filter 9, and further, outside air not blown to the cooling air passage 7 and the exhaust air passage 8 from the inertial separation filter 9 is re-removed in the elimination air passage 5. It circulates and re-enters the inertial separation filter 9. Therefore, the outside air does not leak out of the removal air passage 5 or the vehicle body 1, and the inside of the vehicle body 1 can be prevented from being soiled by dust.

At the time of inspection and cleaning, the inertial separation filter 9 fixed in the removal air passage 5 can be easily cleaned from the inspection port 10 provided on the passage 15 side, and the maintainability is also improved. Since the inspection port 10 is not connected to the outside of the vehicle body 1, dust in the outside air does not enter the gap between the cooling device 20 and the vehicle body 46 and cause corrosion or the like.
According to at least one embodiment described above, since the inspection port is provided inside the vehicle body and the cooling device is formed in a vertical structure, the maintenance work and the assembly are easy without the inside of the vehicle body being contaminated by the external dust. A vehicle cooling device can be realized.
