Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dual-purpose electric appliance box, and relates to a dual-purpose electric equipment box that can be used to prevent termites, provide cooling, and protect the cargo.

In general, there is an Isobo box that stores air pumps, electronics, and other equipment under the floor of the East Railway East Railroad (If-1).

The structure of Kenmai's 1-kirei-ki-tei is shown in Figures 1 to 4. As shown in the figure, this type of equipment box 1 has hanging points 2 at the upper four corners.
This means that there will be 4 dimensions of V under the floor of the body. In addition, this sword box 1 is divided into four blocks 44 (4A to 4 DJ) by a partition wall 3 in the (c) capital.

Each block 44 is equipped with an electric detector 5 (58~5Dl), and block @4 has a cover 6 (6A~5Dl).
6 D) v(opening/closing aJηhi and 1./-h
Ru.

By the way, Shinki Ame IP-! Each piece of equipment is equipped with a heat-reducing size, a vent at an acceptable temperature, and vents above and below the block room as necessary. In the illustrated example, block chamber 4
Upper ventilation lower bear A, 7BIJ on the upper and lower surfaces of A and 4B? and a lower air vent 8 (8A, 8BJ).Therefore, in these block chambers 4A, 4B, outside air enters from the lower air vent 8 and is discharged from the upper ventilation lower, thereby preventing the internal equipment 5A, 8BJ. , 5B are cooled.

On the other hand, block chambers 4C and 4D are not provided with ventilation holes.
In this case, the internal devices 5C and 5D are cooled by convection of indoor air. In this case, devices 5C, 5D
The air that has taken heat from the indoor top and covers 60, 6
Heat transfer 4 is performed to D, and heat is radiated through n and others.

However, in the conventional vehicle electrical equipment box 1, the ventilation lower 8. Cooling effect inside block chambers 4A and 4B! /i
Although it is a pain, since the structure is such that outside air is taken in from under the floor of the heavy vehicle, there is a lot of fine powder and dust from the brake shoes, fibrous TL, etc., and dirt is likely to occur, resulting in an unfavorable state in terms of heat dissipation. For this reason, these dirty parts had to be removed through regular cleaning work, which caused maintenance work problems.
In this case, the internal equipment 5C and 5D are
Equipment 5C does not cause problems with contamination or insulation deterioration.

The 5D's drawback is that its cooling effect is poor. In particular, when devices 5C and 5D are placed adjacent to each other as shown in the figure, I@
If the partition wall 3 that partitions the rooms is not effective as a heat dissipation surface and the desired temperature shielding of the block room 4 at -y is high, heat will be transmitted to the other block room 4, adversely affecting the electrical equipment 5 housed therein.
・There is a problem called boding. Arrow 9v'i in Figure 4
The figure shows that the air temperature in the block 44D is high and heat is transmitted to the block chamber 4C via the partition wall 3.

The purpose of the invention is to provide a complete electrical equipment box for a vehicle that can increase the cooling effect of electrical equipment by achieving thermal insulation between the divided block chambers and in view of the above-mentioned problems of the conventional Io]. In order to achieve the above object, the present invention is to provide a heavy-duty electric cellar having a block chamber divided into six oval parts and a block chamber for accommodating equipment, and at least one of the block chambers being sealed. The chamber is divided into two east-facing electrical boxes, and an outside air circulation section is formed along the partition wall between the sealed block chamber and the adjacent block chamber.Such a structure. According to
Blocks can be prevented from being affected by heat, and ventilation (
This increases the heat dissipation area of each block chamber, thereby increasing the cooling effect of the stored equipment.

Hereinafter, an example of the uninvented dual-purpose electric box will be explained in detail with reference to the drawings. Incidentally, the same configurations as those of the conventional example are given the same numbers, and the description thereof will be omitted.

A first embodiment of the present invention is shown in FIGS. 5 to 8.

As shown in these figures, the equipment box according to this example is installed. 'i, block room 4C, which is considered to be a sealed room.

The equipment box 1O is attached to the partition wall 3 that partitions the partition wall 4D in the state 2, and outside air flow portions 11, 12, and 13 are formed to vertically penetrate along the partition wall 3&C. In other words, sealed block chambers 4C and 4D phases! Two plate materials 14 are used to divide the granite wall, and these plate materials 14 are used to seal the block chambers 4C and 4D, and to form an outside air passage portion 111 that penetrates vertically. Also, one sealed block chamber 4C is formed with a ventilation lower 8 and is adjacent to the rear block chamber 4B, but even if it faces the partition wall V which is the mutual dividing surface, it is still made of two plates 15? (/'1) While forming the wall surfaces of both block chambers 4B and 4C, an outside air ventilation section 12 is formed which is penetrated vertically. Since it is in contact with
6 forms the wall surfaces of both the block chambers 4A, 4D, and forms an outside air flow section 13 that passes through the block chambers 4A and 4D vertically.

In the equipment box 10 having this conventional configuration, in the block chambers 4A and 4B having the ventilation lowers 8, outside air is introduced from the lower ventilation ports 8A and 8B, and the internal equipment 5A
, 5B are exhausted from the upper ventilation lowers A and 7B. - as block chamber 4C, which has a sealed structure;
Since the 4DT has external flow sections 11 to 13 between the block chambers in contact with each other, thermal insulation between the block chambers is achieved.In other words, heat transfer from adjacent block chambers is prevented by external ventilation. It is blocked by the flow parts 11 to 13 i1i',
It is possible to avoid thermal effects on internal equipment. Also,
The plate materials 14 to 16 forming the outside air flow parts 11 to 13 are -
These plates 14 to 16 are in contact with the warm air inside the block chamber and the opposite side is in contact with the cold air outside the box.
Each block chamber 4C through.

It can dissipate 4D heat. As a result, the temperature inside the sealed block chambers 4C, 4D can be lowered compared to the conventional case, and the reliability of the internal devices 5C, 5D can be improved.

Also, using each interview 14-16, sealed block room 4C,
Since the wall surface of 4D is formed and its f closed shape is ensured, the cooling efficiency can be increased without outside air flowing into the sealed block chamber 40.4D and causing no contamination or insulation deterioration. I can do it. Furthermore, a block chamber 4A is provided with a ventilation lower 8.

4B as well, the presence of the outside air flow section 12.13 increases the cooling efficiency within the flock chambers 4A and 4B.

Furthermore, if the temperature in the sealed block chambers 4C, 4D is kept the same as in the conventional case, it becomes possible to downsize the block chambers 4C, 4D and increase the density of the equipment 5. In addition, in the conventional structure, the temperature of the block layer 4 increases, and ventilation lowers are installed above and below the block chamber.
Even in the case where 8 must be provided, the block chamber 4A can be improved by providing 40 outside air ventilation sections 11 to 13 in this embodiment.

4B can be cooled and sealed.

In the above embodiment, each block chamber 4 is completely divided (7
However, it goes without saying that the block chambers 4 are partially communicated with each other through electric wire penetration ports, piping ports, etc. Next, as shown in FIGS. 9 to 12, 2 shows a second embodiment of a vehicle electrical equipment box according to the present invention. In this additional example, in addition to the structure of the first embodiment, an outside air ventilation section 17 is also provided vertically penetrating the partition wall between the block chambers 4A and 4B. An outside air ventilation section 19t is also provided in the central partition along the arrow 18), and horizontal outside air ventilation sections are further provided along the front and rear partition walls. In other words, the entire blocks 4A to 411 are separated by outside air flow portions 11 to 13°17, 19, and 20.

According to such an embodiment, when the vehicle is running, the equipment box
'10, the running wind 21 also flows in from the outside air ventilation section 19 along the direction of travel, causing the other running wind 21Fi inside the outside air ventilation section to exhibit high cooling dynamic characteristics. That will happen. Therefore, as in this embodiment, the ventilation lower 8 can be omitted and the entire block chamber 4 can be completely sealed. As a result, it is possible to prevent contamination due to dust buildup in the block chamber 4, eliminate cleaning maintenance work, and prevent insulation deterioration.

As explained above, according to the present inventor, since the outside air flow section is formed along the partition wall between the block chamber holes q, the thermal form 4# of mutual darkness in each block chamber is completely prevented, and the cooling area is further reduced. By increasing the amount of air, the block chamber can be cooled, and the cooling effect of the entire equipment box can be improved.
