Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device for indoor equipment in a diesel vehicle.

Conventionally, indoor equipment in diesel vehicles has been cooled by introducing air through a cooling air filter installed on the side of the vehicle's hood and flowing it directly or indirectly around the indoor equipment that requires cooling. can be cooled. According to such a conventional method, there is an effect of lowering the temperature of the entire room, and therefore, it becomes possible to indirectly cool the indoor equipment based on the temperature difference between the indoor equipment.

However, with such conventional cooling methods, the cooling effect is insufficient for indoor equipment that has locally high temperature parts, such as the air discharge part of a brake air compressor, the intake and exhaust valves of a vacuum machine, and their surroundings. This is particularly inappropriate for use in high-temperature areas, and since the entire interior of the vehicle is under negative pressure, which is lower than atmospheric pressure, there is a possibility that dust may enter the air through gaps such as doors.

1 and 2 are explanatory diagrams showing a diesel vehicle in which the above-mentioned conventional cooling method is adopted.
An engine 3 and a main generator 4 are installed in the
Cooling air can be introduced by an air filter 5 and a main motor blower 6. Engine room 2
A blower 8 is installed in the cooling chamber 7 that follows.
In addition, in the equipment room 9 following the cooling room 7, a vacuum machine 10 is installed.
A brake air compressor 11 is installed, and cooling air is introduced by an air filter 12 and a blower 13.

The equipment that requires cooling in the equipment room 9 of such a diesel vehicle is the vacuum machine 10 and the air compressor 11, but these equipments are cooled through an air filter 12 provided on the side of the equipment room 9. , by the flow of air sucked in by the blower 13. Therefore, the suction port of the blower 13 and the air filter 1
If the arrangement relationship with 2 is not set appropriately, the vacuum machine 10 and air compressor 11 that require cooling
It becomes difficult to cool each high-temperature part. However, the setting position of the blower 13 is also related to the air passage embedded in the vehicle body frame, and in cases where it is virtually impossible to arrange the equipment so that the high-temperature parts of the equipment as described above can be appropriately cooled. There are many.
Furthermore, since the air filter 12 is attached to the door, there is a problem in that dust can enter through the gap between the air filter 12 and the door.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a method for cooling indoor equipment in a diesel vehicle, which is capable of effectively cooling vehicle equipment.

In the present invention, an engine room equipped with an engine, a main generator, an air filter, and a blower for the main motor is arranged adjacent to the driver's room, and a cooling room equipped with an air blower is arranged adjacent to the side opposite to the driver's room of the engine room. In a diesel vehicle having an equipment room equipped with a vacuum machine and a brake air compressor on the opposite side of the cooling room to the driver's cabin, a portion of the cooling air from the traction motor blower installed in the engine room. A duct is provided to lead the equipment to the equipment room, and the equipment room and the cooling room are connected to each other.
This cooling chamber is connected to the cooling chamber so that the air inside the equipment chamber can be sucked by a blower installed therein.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is an explanatory diagram showing an embodiment of the cooling method for indoor equipment in a diesel vehicle according to the present invention, and the same members as those in the conventional example are given the same reference numerals and the explanation will be omitted. . In this embodiment, an air filter 15 is installed in a filter chamber 14 that is provided independently between the driver's cab 1 and the engine compartment 2. This filter chamber 14 is connected to the suction port of the traction motor blower 6, and a duct 16 is provided at the discharge portion of the traction motor blower 6 to guide cooling air to all parts of the locomotive. A branch duct is connected to equipment that requires cooling, making it possible to blow cooling air directly to the high-temperature parts of the equipment that require cooling. Further, the partition wall 2 between the equipment room 9 and the adjacent cooling room 7 is provided with a through hole 18 of an appropriate size. In addition, in the figure, 17 indicates the main motor,
In addition, the partition wall between the cooling room 7 and the equipment room 9 is equipped with a blower 8.
It functions as a suction side duct.

According to the above embodiment, the high temperature parts of the equipment that require cooling are directly cooled by a portion of the cooling air from the main motor blower 6, and the entire equipment room 9 is cooled by the cooling air. It becomes possible to completely prevent dust from entering by applying pressure. Further, in order to make the flow of cooling air effective, a through hole 18 is provided in the suction side duct of the blower of the adjacent engine cooling device.
It is now possible to effectively regulate the flow of cooling air from the traction motor blower 6, and even when the discharge capacity of the traction motor blower 6 is insufficient, the engine cooling system blower can control the air flow in the equipment room. This makes it possible to promote cooling of equipment effectively.

As described above, according to the method for cooling indoor equipment in a diesel vehicle according to the present invention, a high cooling effect can be obtained.
