Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an axle control device (41) mounted under the floor of a vehicle body such as a railway car, and is a self-cooling wheel control device that releases heat from an internal heating element through natural cooling air. Regarding equipment.

In general, vehicle control devices use heating elements such as semiconductor elements, and cooling them is an important issue in terms of device performance and reliability. Examples are shown in Figure 1 (a), <Sakaki and Figure 2 (a)
) e (b) From K, Figure 1 (a),
(b) is a device housing mounted under the floor of the vehicle body 1! A blower 3 is provided at the end in the longitudinal direction, and by the operation of this blower S, outside air is forcibly drawn from the filter 4 into the device casing 2 and is blown to the semiconductor element 5, which is a heating element, for cooling. It is a cold method.

On the other hand, recently there has been a demand for a self-cooling system that does not use a vacuum cleaner or S- because of problems such as maintenance of the Proa 3, reliability in noisy environments, and equipment pollution. This is the 2nd WJ(a),
As shown in (k), there is an air passage 6 that vertically penetrates inside the device casing 2.
A cooling fin 5 for the semiconductor element 5 is provided in the air passage 6.
3 is an enlarged cross-section of the self-cooling type control device described above. The upper end of the equipment casing 2 is suspended under the floor of the vehicle body 1. The equipment casing 2 is fixed to the frame 1 with bolts and nuts 8. Compared to the above-mentioned cooling method, the cooling efficiency of the car control device using the air cooling method with open upper and lower ends, which is arranged with the fins protruding, is lower than that of the above-mentioned cooling method. Because of the circulation jlK, it is constrained from below to above. Therefore, in order to increase the cooling efficiency, it is necessary to give special consideration to the structure of the cooling section, the configuration of the equipment I, the flow of cooling air, etc. is also greatly affected. In other words, with this type of self-cooling type vehicle control device, there is no problem if the heat radiation is small and the vehicle generates heat only while the vehicle is running, but if the vehicle generates a large amount of heat and generates heat even when the vehicle is stopped, the vehicle body There was a problem in that the area under the floor of No. 1 was heated, which adversely affected the underfloor piping and the wiring @XS. In addition, the cooling effect cannot be obtained sufficiently due to the poor air exhaust efficiency from the upper exhaust outlet 6a of the wind duct 6 to the vehicle body l side [7 m outward], Due to consideration such as widely distributing power to the heating elements such as the semiconductor elements 5 in the device housing 1,
There was a problem that the entire device became a large lid and was heavy.

Therefore, as shown in FIG. 4, by attaching the device housing 2 at a large distance from under the floor of the vehicle body 10, it is possible to increase the efficiency of exhausting the air from the upper exhaust port 6a of the air passage 6 to the outside of the vehicle body side surface 1a. However, due to the 140-space restriction of this pigeon coop vehicle, the vertical height of the device housing 2 had to be reduced and made flat, and the width or length had to be increased accordingly. In addition, due to restrictions on the internal electrical components 10, etc., the vertical height dimensions cannot be made very small, and it is therefore very difficult to construct the device as shown in FIG. 4.

Exhaust air (hot air) coming out of trench 9 and upper exhaust outlet 6 &
0 There is a possibility that the air will stay in a place where it cannot be dispersed by the traveling wind, such as the central part under the floor, and there are problems such as not improving the ventilation efficiency and increasing the temperature of the underfloor cable and the underfloor.

This invention has been made in view of the above circumstances, and its purpose is to greatly increase the efficiency of exhausting air outward from the vehicle body side from the upper exhaust outlet of the air passage of the device casing. To provide a self-cooling type vehicle control device which can solve thermal problems under the floor of a vehicle body, reduce cooling efficiency, and reduce the weight of the lid as a whole.

tb.This invention is constructed by lowering the upper surface of the vehicle body part above the airway of the storage case, so that the exhaust air from the air outlet at the upper part of the windway can be efficiently discharged to the outside of the vehicle body side. It is characterized by nine vehicle control devices.

The first embodiment of this invention will be described below with reference to FIGS. 5(a) and (b).
and Fig. 6). In the drawings, parts having the same configuration as those shown in FIGS. 1 to 4 above are denoted by the same reference numerals to simplify the explanation.

Here, 2mm in the figure is the equipment housing, which has a configuration comprising 9mm of the front room for housing the semiconductor device 5, 6mm for the air passage passing through the top and bottom, and 12mm for storing the electrical components 10 and 9 equipment. be.

And this equipment housing 2m is the wind path 4m) Side 1 of the car body 1 @
The upper surface 15 of the side part, that is, the upper surface 15 of the book-closing chamber tom is on the opposite side (
It is formed one step lower than the upper surface 16 of the equipment storage chamber 12 of the vehicle body 1 (center side under the floor).

The distance between the upper surface 15 and the underfloor of the vehicle body 1 is set to be twice as large as the distance between the upper surface 16 and the floor. In addition,
The height of the device housing 25 as a whole when installed under the floor of the vehicle body 10 is the same as that of the conventional 4 shown in FIG. It becomes.

Further, the upper air outlet dAa of the air passage 6m is opened at an angle from the higher end of the upper surface 16 to the lower end of the upper surface 15 Kl. That is, the exhaust port 16km is configured to be inclined downward toward the side surface la of the vehicle body 1.

Therefore, in the vehicle control device having the above-mentioned configuration, the device housing 2
Since the upper surface 15 of the sealed chamber 9A located on the side of the vehicle body is lower than the air passage 6A of the vehicle body, there is a large gap between the air outlet 6A and the underfloor from the side surface 1a of the vehicle body. The exhaust air (hot air) coming out from the upper exhaust outlet dAa from the inside passes through a large gap between the underfloor and the top surface I5, and then reaches the vehicle body! It becomes easier for air to escape outward from the side surface 1a, greatly increasing cooling efficiency, and conversely, the upper surface 16 on the center side of the vehicle body becomes higher than the air passage 6A of the device housing 2A, making it difficult to connect with the underfloor. Because the gap is narrow, the exhaust air (hot air) coming out of the exhaust port 1Aa will flow toward the center under the floor of the vehicle body 10*aii<, and will be smoothly discharged to the outside of the vehicle body side where the gap is wide. Therefore, the inconvenience of hot air staying at the center side under the floor of the vehicle body 10 and overheating the underfloor is also eliminated. In addition, when running, the running wind passes through between the top surface 15 of the device housing 2A and the underfloor, and this causes the air to flow through the exhaust port 6A.
The exhaust air (hot air) that comes out of the field is definitely blown away and escapes to the outside of the car body. As described above, since the air exhaust efficiency is improved and the cooling efficiency is increased, the element cooling fins jm protruding into the air passage 6 of the device housing 2 can be made smaller, and the semiconductor elements 5 in the sealed chamber 9A can be arranged densely. It is now possible to
This makes it possible to reduce the weight of the device casing.

In addition, the 12-m equipment storage room on the central side under the floor of the multi-vehicle body for the 6-person air passage in the 2-m equipment cabinet can be kept at the same height as the conventional one.
It is possible to use the same electrical component 10 as in the past, and there is no problem of increasing costs.

Furthermore, in the first embodiment, the upper exhaust port 6m of the wind passage 6A is opened outwardly from the vehicle body side so as to be inclined downward, and the exhaust air ( Hot air flows outward toward the vehicle body, making it easier to escape and improving cooling efficiency.

The 7th WA shows the second embodiment of this invention.

In ζζ, the upper ventilation opening 6b of the air passage 6A of this bale storage case 2m is inclined as shown in FIG. has a plurality of air conditioning guide plates 6b'... each curved and arranged in parallel. ) will be reliably directed outward toward the vehicle body and flow out efficiently.

FIG. 8 shows a third dormitory embodiment of this invention.

In this case, open the upper ventilation outlet 6m of the air passage 6A in the equipment case 1m,
It extends over the lowered upper surface 15 and extends outward toward the vehicle body in a long duct shape. t9凰道6A
The air exhaust port 11 is formed by connecting nine ducts 6A bent outward toward the vehicle body at the upper end of the duct 6A.
K so that the exhaust air (hot air) is guided out to the outside of the vehicle body through the inside of g'. Note that four air conditioning guide plates 6Ae' may be provided within this duct 6Ae'.

FIG. 9 shows a fourth embodiment of the present invention, in which side wall portions 6A d' of a duct 6' forming an air outlet 614 similar to the third embodiment shown in FIG. It has a good mesh structure, which makes it easier to diffuse the exhaust air as the wind enters the vehicle.

FIG. 10 shows a fifth embodiment of the present invention, in which the upper end exhaust port 6A of the air passage 6A of the device casing 2m is lowered one step and is opened horizontally at the same height as the upper surface 15. It's soke.

FIGS. 11 and 12 show a sixth embodiment of the present invention, in which the exhaust port IAf of the air passage dm of the device casing 2A is connected to the top surface 15 of the airtight 119 of the device casing 2A, and furthermore, The structure consists of nine top plates 11 installed on the upper side, and a scissor exhaust port 6A.
