Description

[Detailed Description of the Invention] Is the present invention an inverter installed in a vehicle? [This invention relates to a vehicle control device such as a dJm splitter chopper control device, and particularly relates to a vehicle control device in which the arrangement of control device parts is rearranged.

Generally, a vehicle control device includes a cooling device for cooling electrical components such as semiconductor elements, etc., in a frame 1 installed under the floor of a vehicle body (not shown), as shown in FIGS. 1 and 2. We are waiting for the other electrical parts to be assembled. The cooling device is composed of a refrigerant evaporator 2 that heats and evaporates liquid refrigerant using the heat of the semiconductor element, a condenser 3 that liquefies the evaporated refrigerant, and a conduit 4 that retards both. ,
On the other hand, other electrical parts include a mud remover reactor, a current balancer, a commutation reactor, etc., a glue handle 6, electronic parts 5A,
This constitutes the 5B equal system @ device.

Both of these parts are attached to the inside of the frame 1, but some of these parts do not like dust, so a partition plate 7 is provided inside the frame 1 to distinguish them. There is.

On the side where the reactor 6 is disposed, ventilation windows 8A to 8D are provided to allow outside air 9 to pass therethrough for cooling.

Although it is possible to obtain a satisfactory control device with the above configuration, it has been found that there are the following problems. That is,
This is a problem caused by the magnetic flux of the reactor 6. Control of the above configurationllll! If there are no other electrical equipment or wiring placed near the underfloor of the car body where the I device is installed, there will be no problem, but in addition to the control device with the above configuration, there are many other types of control devices under the single floor. Since the control device, the signal line, and the signal line are arranged and wired incorrectly, these guys are the reactor 6.
If it is placed within the range of the magnetic flux 10 emitted from the magnetic flux 10, it will cause an inductive disturbance due to the magnetic visiting effect.

In order to prevent the influence of the magnetic flux of the accelerator 6, the surroundings of the reactor 6 are covered with temporary shields 11A and 11B.
It is possible to prevent the magnetic flux 10 from leaking to the outside of the control device by covering it with shield plates 11A and 11B, but this can be prevented by shielding it with shield plates 11A and 11B. Since the ventilation windows 8A and 8B are blocked, the reactor 6, electronic components sB, and WM unit 3 cannot be cooled sufficiently, so the size of the tank must be increased.
vi, there is often a problem where it disappears.

The present invention has been developed in view of the above points, and its primary objective is to provide a vehicle control system that can reduce induction disturbances without impairing the cooling effect.

In order to achieve the above object, the invention incorporates a reactor and a plurality of control device parts within the frame. In the I11 control device, of the frame body and the control device parts, those provided with magnetic mulch material are rearranged around the reactor.

Is this just a joke about the invention? 1J is dedicated for Figure 3 and Figure 4. Since the same reference numerals as in FIGS. 1 and 2 indicate the same parts, a detailed explanation will be omitted again. The size of the frame 10 installed under the floor of the vehicle body is exactly the same as the conventional frame.

However, the vertical partition plate 7 was provided inside, and the ventilation window 8
The positions of A to 8C are slightly different. That is, by providing the vertical partition plate 7 on the frame lFF3, the control i! I space A on the left and right for device parts.

Ventilation windows 8A to 8Ci are provided at the top and bottom and sides of the frame 1, which forms the space B in which the outside air is cooled and parts are rearranged, and the outside air 9 is directed downward.・It is made to pass upward from the side blade or upward from the side blade.

On the other hand, among the parts arranged inside the frame 1, cooling.

The structure of the device is much larger and of better quality than before.

This cooling system is composed of the refrigerant evaporator 2, the refrigerant evaporator 3, and the pipe line 4, as described above, but the pipe line 4 is extended almost horizontally from the refrigerant evaporator 2. However, the point of connecting the chapter lower part of the tsumugi 3 to the end of the extension makes it very interesting for the cooling 9 & placement of the rice. By forming the components of the cooling device into a three-way device in this manner, the components of the control device according to the present invention can be arranged in the same space as in the conventional case.

Next, the arrangement of each control device component within the frame 1 will be specifically explained. First, the basis for component placement is the cooling system. A refrigerant evaporator 2 of a cooling device is placed in the lower part of a space A partitioned by a partition plate 7. A conduit 4 for guiding the steam in the evaporator 2 is passed through the partition plate 7 so as to have a slightly upward slope, and is exposed to the adjacent space B. On the other hand, the condenser 3 of the cooling device is supported in the space B such that its lower part is connected to the end of the front conduit 4.

Moreover, if the cooling device can be rearranged, the remaining components can be rearranged more easily. In other words, it is only necessary to use a cooling device to cover the occupied heat and the remaining space as appropriate, and place electronic components in space A that are in contact with the outside air or do not need to be cooled.
8, and in space B there is a reactor 6 and an electronic component 5H.
'jz will be reassigned. The height of the reactor must be 6 and the height above the QJ recorder 3 must be dimensioned.

Since the front reactor 6 is located above the condenser 3, the magnetic flux 10 generated by the reactor 6 passes as a part of the magnetic path of the Nth condenser 3, so the magnetic flux 10 passes through the frame 1. There is almost no leakage from the outside of the reactor 69 (').There is nothing on the top of the reactor 69 and the ventilation window 8C is open, so the magnetic flux 10 from above the reactor leaks. Just by installing a mounting seat for attaching the frame 1ffi under the floor of the upper chest of drawers, there is no need for any other equipment to be placed, so there is no need for a special magnetic shield.

On the other hand, if the reactor 6' is placed on the F side of the condenser 3, there will be nothing to prevent leakage of magnetic flux, as in the conventional case, and the arrangement will not be appropriate.

1. Place the rear turret 6 above the condenser 3 and approach the partition plate 7.

The ventilation window 8BZ) on the side and the whole frame 1 are exposed to the medium heat (Fig. 4). With this arrangement, leakage of the magnetic flux 10 to the outside through the ventilation window 8Bllll is reduced 9, and even if other electrical equipment or wiring is found nearby, there will be no influence due to electromagnetic induction.

The outside air 9 enters the lower ventilation window 8A70 and exits through the upper ventilation window 8C, resulting in a flow from bottom to top. There's no harm in it.

By the way, in the Nt embodiment, a reactor 6 and an electronic component 5B are arranged adjacent to each other above the vertical motion device 3. However, if the electronic component 5B is made of a type that is easy to cause induction disturbances, the above arrangement becomes a problem. If this arrangement is made, the condenser 3 will cut off the magnetic field, thereby avoiding induction disturbances.

On the other hand, since the parts in the darkness B are mostly cooled by the outside air 9 flowing over the lower part, it is also possible to eliminate the ventilation window 8Bτ of the glls. If this is done, even if the cutting reactor 6 is placed at the position of the electronic component 5B, there will be no leakage of the heat exchanger 10 to the outside.

As described above, in the above embodiment, the reactor 6 is placed above the magnetic flux 3, and the vertical mfir 3 is effectively used as a part of the magnetic path, thereby preventing the magnetic flux 10 from leaking to the outside. This is how it was done. However, in this case, the PfrJ-written condenser 3 must be made of a specially-crafted material, but the penile spring 3 can be made of a magnetically conductive material such as aluminum, stainless steel, or copper. do not have. In JIiJ, where the inscription coagulator 3 is made of a non-magnetic conductive material, since it is used as an ayu, the magnetic flux 10i that is about to leak to the outside is not likely to disappear.

Furthermore, although the explanation in i'1 assumes that the three cooling benefits of the cooling system structure will be actively utilized in three ways, for example, the arrangement shown in Figures 5 and 6 may also be used. It can have some effect. In this case, it is necessary that the electronic component 5B be covered with a case made of a non-magnetic conductive material such as aluminum.

That is, although the arrangement of the partition plate 7 that partitions the inside of the frame 1 is concave as in the conventional case, it is different from the conventional side ventilation window (Fig. 2, 8B)' (
The reactor 6 is placed close to the upper ventilation window 8C9IJ, and the electronic component 5B is placed on the lower ventilation window 8A side instead.

By configuring the notation in this way, the reactor 6 is covered by the front plate IA of the frame 1 and the condenser 3 on the front and back, and the left center is covered by the side plates IB and IC on the left and right 5, respectively, and the reactor 6 is covered with the Since the electronic component 5B covered with a non-magnetic conductive material case is located in , although the leakage peak flux lO that leaks upward from the frame 1 is recognized, the magnetic flux 10 that leaks from the sides and below can be almost suppressed. However, it is possible to couple the original purpose. By adopting this structure, the arrangement of the components of the cooling system can be arranged and the left and right equipment can be fully utilized in the same vertical arrangement as before, so the 11 parts of the conventional control@I equipment can be utilized. There are 10 things.

As explained above, in a control device that has a reactor built into a frame body that is inventively attached to the vehicle body, control device parts equipped with magnetic scattering materials are arranged around the accelerator. , the magnetic flux of the front axle can be prevented from leaking from the external frame of the control frame by blocking it with the magnetic scattering material of the control iron of Ml-, and therefore the magnetic flux of the front axle can be suppressed from leaking into the vicinity of the control device. Even if different electrical machine numbers and wiring are allocated, the influence of the electrical equipment and wiring will be reduced.

Moreover, since there are no particularly large changes to the cooling air passages that separate the direct parts of each control TC, the cooling effect does not get used to.
