Description

Body water cooling system

The present invention relates to a technique for water cooling a vehicle body of a vehicle.

When the vehicle is parked for a long time under the summer sun, the body that has continued to receive sunlight gets hot. As a result, the passenger compartment becomes hot and feels uncomfortable when the occupant enters the passenger compartment. In order to avoid such a situation, various techniques for cooling the vehicle body have been proposed.

For example, Patent Document 1 describes a vehicle body heat prevention cooler composed of a tank installed on the roof of the vehicle body. This tank has a small hole formed on its lower surface, and when water is stored in the tank, the water in the tank flows out of the hole and the vehicle body is water-cooled.

Japanese Utility Model Application Publication No. 63-30246

In order to sufficiently cool the entire vehicle body evenly, it is necessary to make the water uniformly contact the entire surface of the roof of the vehicle body. For that purpose, for example, a tank having the same shape and size as the roof of the vehicle body may be prepared, and a plurality of holes may be formed on the lower surface of the tank so as to be evenly distributed, and water may flow out from each hole. However, the shape and size of the roof of a vehicle body are various, and when it is going to manufacture the tank of the shape and size which fitted the roof of each vehicle body, it becomes difficult to hold down manufacturing cost, since it becomes a multi-product small amount production.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle body water cooling device capable of sufficiently cooling a vehicle body of various shapes and sizes while suppressing the manufacturing cost.

The present invention made to solve the above problems is

Equipped with

In the above configuration, the “unit shape” is a constant shape and size defined independently of the shape and size of the roof of the vehicle body. A plurality of types of shapes or a plurality of types of sizes may be defined as the “unit shape”. The plurality of unit tanks provided in the vehicle body water cooling device may all have the same unit shape, or a plurality of unit shapes may be mixed.

When the vehicle body water cooling device is installed on the roof of the vehicle body, the water filled in each unit tank leaks to the roof of the vehicle body through the tank through holes provided on the bottom plate, thereby cooling the vehicle body Be done. Here, since a plurality of unit tanks are integrally supported by the support member, vehicle bodies of various shapes and sizes can be obtained simply by changing the arrangement mode (number and arrangement of unit tanks). The roof can be cooled almost evenly. The unit tank can be mass-produced because it is a predetermined unit shape defined regardless of the shape and size of the roof of the vehicle body, and the manufacturing cost can be effectively suppressed.

Here, after the communication port of the partition plate is closed, water continues to leak from the tank through hole until the water stored in the space below the partition plate is exhausted. When the partition plate is provided close to the bottom plate, the leakage of water from the tank through hole is stopped substantially at the same time as closing the communication port. On the other hand, when the partition plate is provided apart from the bottom plate, leakage of water from the tank through hole continues for a while after closing the communication port, and the leakage stops after a predetermined time has elapsed. That is, depending on the height at which the partition plate is disposed in the unit tank, it is possible to appropriately define the response time until the leakage of water from the unit tank is actually stopped after the communication port is closed.

Preferably, in the vehicle water cooling system,

In this configuration, when the operating member is disposed at a position where the supporting through hole formed in the operating member overlaps the communication port formed in the partition plate, the plug member enters the communication port In other words, the communication port is closed by the plug member. From this state, when the user grasps one end of the operation member projecting to the outside of the unit tank and pulls out (or inserts) it, the support through hole and the plug member supported thereon are connected from the communication port It becomes the position which deviated. That is, the plug member is in a state of being withdrawn from the communication port (that is, in a state in which the communication port is open). According to this configuration, the on-off valve device can be simplified.

In addition, when the container is configured to have heat resistance, the temperature of the water stored in the unit tank is prevented from rising, so that the cooling effect of the vehicle body is improved. And even if it is the structure accommodated in a storage container, since the inlet of a unit tank is located in the lower part of the opening of a storage container, water can be easily inject | poured into a unit tank from an inlet through an opening.

In the above configuration, preferably, the apparatus further comprises a guide member for guiding the water injected into the opening of the container to the inlet of the unit tank housed in the container.
In this configuration, the water injected into the opening can reliably flow into the unit tank.

According to the present invention, since the plurality of unit tanks are integrally supported by the support member, it is possible to cope with vehicle bodies of various shapes and sizes only by changing the arrangement of the unit tanks. , The roof can be cooled almost evenly. In addition, since the unit tank is a predetermined unit shape which is defined irrespective of the shape and size of the roof of the vehicle body, it can be mass-produced, and the manufacturing cost can be effectively suppressed.

<1. Overall configuration>
FIG. 2A and FIG. 2B show the overall configuration of a vehicle water cooling system according to the first embodiment. Here, a vehicle water cooling apparatus 100a mounted on a vehicle body 9a (see FIG. 1A) of a sedan type passenger car and a vehicle water cooling apparatus 100b mounted on a vehicle body 9b (see FIG. 1B) of a truck will be described as an example. Although both body water-cooling devices are different in shape and size, the basic configuration is common, so they will be described together. In the following description, the sides corresponding to the front, rear, left, and right of the vehicle body are defined as the front, rear, left, and right of the vehicle body water cooling devices 100a and 100b.

As shown in FIGS. 1A and 1B, the vehicle body water cooling devices 100a and 100b are placed and fixed on the roofs 91a and 91b of the vehicle bodies 9a and 9b. This fixing may be performed in any manner, and for example, an adhesive such as a suction cup or a seal, fixing by a magnet, screwing, or the like can be used.

The vehicle body water cooling device 100a, 100b includes a plurality of unit tanks 1 and storage containers 2a, 2b for storing them inside. The unit tank 1 has a fixed shape and size (unit shape) set based on the size and shape of a general vehicle body such as a passenger car or a truck, and the specific size and shape of the vehicle body 9a, 9b It is defined irrelevantly. That is, the unit tank 1 is a general-purpose component shared between the vehicle water cooling devices 100a and 100b corresponding to the vehicle bodies 9a and 9b of various vehicle bodies having different sizes and shapes. On the other hand, the storage containers 2a and 2b have a shape and size defined in accordance with the size and shape of the vehicle bodies 9a and 9b, and are formed for each of the vehicle water cooling devices 100a and 100b corresponding to the vehicle bodies 9a and 9b. It is a dedicated part.

<1-1. Unit tank>
The configuration of the unit tank 1 will be described with reference to FIG. FIG. 3 is a cross-sectional view of the unit tank 1 cut along a vertical plane.

The unit tank 1 is provided on the lower surface side of the unit tank 1, a case 10, switching means 20 for switching leakage / non-leakage of fluid (herein, “water”, hereinafter referred to as water) from the case 10. And a water holding member 30.

<1-1-1. Case>
The housing 10 is a rectangular parallelepiped container for storing water inside, and is configured by liquid-tightly joining a rectangular top plate 11, a peripheral wall 12 and a rectangular bottom plate 13. However, the housing 10 may be one in which the respective portions 11, 12, 13 are integrally formed. As a forming material of the housing 10, a synthetic resin or the like is preferable.

The top plate 11 and the peripheral wall 12 are provided with an inflow port 111 and four inflow ports 121 for allowing water to flow into the housing 10, respectively. The inlet 111 is provided substantially at the center of the top 11. The inlets 121 are provided substantially at the centers of the four surfaces of the peripheral wall 12. Further, a slit 122 which is long in the width direction of the peripheral wall 12 is formed in a lower part of the predetermined one surface of the peripheral wall 12 than the inflow port 121. An operation member 222 described later is inserted into the slit 122.

The bottom plate 13 is formed with a through hole (tank through hole) 131 for leaking water from the inside of the housing 10. The tank through-hole 131 has an inverted truncated cone shape whose diameter decreases as it goes downward. Preferably, a plurality of the tank through holes 131 are formed as illustrated. The plurality of tank through holes 131 are preferably formed (for example, arranged in a matrix) so as to be uniformly distributed in the plane of the bottom plate 13.

<1-1-2. Switching means>
The switching means 20 is an element that switches between a state in which water leaks from the tank through hole 131 and a state in which water does not leak from the tank through hole 131, and includes a partition plate 21 and an on-off valve device 22.

The partition plate 21 is a member that divides the inside of the unit tank 1 into upper and lower parts. Specifically, the partition plate 21 is a plate-like member having substantially the same shape as the bottom plate 13 of the unit tank 1 and disposed in the unit tank 1 in a posture parallel to the bottom plate 13. In the whole, it is liquid-tightly fixed with respect to the inner surface of the surrounding wall 12. The height at which the partition plate 21 is disposed in the unit tank 1 can be arbitrarily determined, but here, the height is assumed to be disposed close to the bottom plate 13 in a non-contact manner. As a forming material of the partition plate 21, a synthetic resin etc. are preferable. The partition plate 21 is formed with an opening (communication port 211) for communicating the upper space (hereinafter simply referred to as "upper space") with the space therebelow (hereinafter simply referred to as "lower space").

The on-off valve device 22 is provided at the communication port 211 formed in the partition plate 21 and switches the communication port 211 between the open state and the closed state, and includes the plug member 221 and the operation member 222.

The plug member 221 is a member that enters the communication port 211 and closes it. Here, the communication port 211 is circular, and the plug member 221 is a ball-like member having a diameter larger than the inner diameter of the communication port 211. The plug member 221 is formed of, for example, stainless steel or the like.

The operation member 222 is a member that switches between a state in which the plug member 221 has entered the communication port 211 and a state in which the plug member 221 has exited from the communication port 211. Specifically, the operation member 222 is a plate-like member formed of stainless steel or the like, and a circular support through hole 2221 for supporting the plug member 221 is formed in the surface thereof. The inner diameter of the support through hole 2221 is smaller than the outer diameter of the plug member 221 and larger than the inner diameter of the communication port 211.

The operation member 222 is inserted into the slit 122 formed in the peripheral wall 12 of the unit tank 1, one end side thereof is disposed outside the unit tank 1, and the other end side above the partition plate 21 in the unit tank 1 It is disposed close to each other in a noncontact manner. The user holds the one end of the operation member 222 from the outside of the unit tank 1 and inserts and removes the end from the unit tank 1 to switch the communication port 211 between the open state and the closed state. That is, when the operation member 222 is inserted into the unit tank 1 by a predetermined length and disposed at a position where the support through hole 2221 and the communication port 211 overlap, the support member 222 is supported on the support through hole 2221 The plug member 221 is in a state of entering the communication port 211, and the communication port 211 is closed (FIG. 5A). From this state, when the operation member 222 is pulled out, the support through hole 2221 and the plug member 221 supported thereon are at positions away from the communication port 211. That is, the plug member 221 is in a state of being withdrawn from the communication port 211, and the communication port 211 is opened (FIG. 5B).

When the communication port 211 provided in the partition plate 21 is opened, water flows from the upper space into the lower space, and the water leaks from the tank through hole 131 formed in the bottom plate 13. On the other hand, when the communication port 211 provided in the partition plate 21 is closed, the inflow of water from the upper space to the lower space is stopped. In this embodiment, the partition plate 21 is provided close to the bottom plate 13, and the volume of the lower space is small. Therefore, the leakage of water from the tank through hole 131 is stopped substantially at the same time as the communication port 211 is closed.

Note that, as described above, the operation member 222 is disposed close to the partition plate 21 in a non-contact state, so that water is allowed to rapidly flow from the space above the unit tank 1 to the space below via the communication port 211. Preferably, as shown in FIG. 5B, the operating member 222 is pulled out from the upper side of the communication port 211 to a position where it is completely retracted.

<1-1-3. Water holding member>
The water holding member 30 is provided on the lower surface side of the bottom plate 13 so as to close the opening on the lower end side of the tank through hole 131. The water holding member 30 is formed of a material (specifically, for example, a woven fabric, a non-woven fabric, a sponge, etc.) capable of holding water, and absorbs water leaked from the tank through hole 131. The water retaining member 30 may entirely cover the lower surface side of the bottom plate 13 as illustrated, or may cover only the opening on the lower end side of each tank through hole 131 and the peripheral portion thereof. It may be.

<1-2. Containment container>
The configuration of the storage containers 2a and 2b will be described with reference to FIGS. 4A and 4B. FIGS. 4A and 4B are cross-sectional views of the storage containers 2a and 2b cut along a horizontal plane.

The storage containers 2a and 2b include a housing 40. The housing 40 is a rectangular parallelepiped container in which water is stored, and is configured by joining the top plate 41 (see FIG. 5A), the peripheral wall 42, and the bottom plate 43 in a liquid tight manner. As a forming material of the housing 40, a synthetic resin or the like is preferable.

The top plate 41 is provided with an inlet 411 for injecting water into the housing 40 (see FIG. 5A). The inlet 411 can be closed with a cap 412 or the like (see FIG. 5A).

At a predetermined position of the peripheral wall 42, a slit 421 for inserting the operation member 222 of the unit tank 1 is formed. Inside the slit 421, a seal member (for example, rubber packing) is provided to seal so that water does not leak from between the slit 421 and the slit 421 when the operation member 222 is inserted.

The bottom plate 43 is a flat plate member having substantially the same shape and the same size as the roofs 91a and 91b of the vehicle bodies 9a and 9b on which the vehicle body water cooling devices 100a and 100b are installed. For example, when the roofs 91a and 91b are provided with an antenna or the like, it is also preferable that the bottom plate 43 be provided with a recess or the like at a position corresponding to the antenna or the like.

The bottom plate 43 is provided with a plurality of regions (tank placement regions 432) in which the unit tank 1 is disposed, and each region 432 includes one or more (preferably, a plurality of) through holes (container through holes The outer through hole of the present invention) 431 is formed. The number and layout of the tank placement areas 432 provided on the bottom plate 43 can be arbitrarily defined. For example, as in a passenger car, in the case of a relatively large rectangular roof 91a, four tank arrangements are provided on the bottom plate 43 so that four rectangular unit tanks 1 are arranged in a matrix (FIG. 2A) Region 432 is formed. On the other hand, in the case of a relatively small rectangular roof 91b like a truck, two tanks are arranged on the bottom plate 43 so that two rectangular unit tanks 1 are arranged in a line (FIG. 2B). A placement area 432 is formed.

The plurality of unit tanks 1 are arranged in the tank arrangement area 432 of the bottom plate 43 and fixed using screws or the like. As a result, the plurality of unit tanks 1 are placed on the bottom plate 43 in an arrangement that occupies an area corresponding to the shape and size of the roofs 91a and 91b.

When the unit tank 1 is fixed to the tank arrangement area 432 of the bottom plate 43, the tank through hole 131 of the bottom plate 13 of the unit tank 1 and the container through hole 431 of the bottom plate 43 face each other. That is, the tank through holes 131 of the bottom plate 13 of the unit tank 1 and the container through holes 431 provided in the respective tank disposition areas 432 of the bottom plates 43 of the storage containers 2a and 2b are the same in number and arrangement. .

<2. Production mode>
A production mode of the vehicle body water cooling apparatus 100a, 100b will be described with reference to FIGS. 1A to 4B.

First, a plurality of unit tanks 1 are manufactured. The unit tank 1 can be mass-produced relatively inexpensively because it has a predetermined unit shape defined regardless of the shapes and sizes of the roofs 91a and 91b of the vehicle bodies 9a and 9b.

Next, the bottom plate 43 is prepared according to the shape and size of the roofs 91a and 91b of the vehicle bodies 9a and 9b on which the vehicle body water cooling devices 100a and 100b are installed. The bottom plate 43 has a tank arrangement area 432 corresponding to the shape, size, and arrangement of the unit tank 1 accommodated in the accommodation containers 2a and 2b, and a container through hole 431 is formed in each tank arrangement area 432. There is. Then, the unit tank 1 is disposed in each tank disposition area 432 of the bottom plate 43, and each unit tank 1 is fixed to the bottom plate 43.

Subsequently, the peripheral wall 42 is joined to the bottom plate 43. At this time, the operating member 222 protruding from each unit tank 1 is inserted into the slit 421 formed in the peripheral wall 42. Thereafter, the top plate 41 is joined to the peripheral wall 42. Thus, the storage containers 2a and 2b in which the plurality of unit tanks 1 are stored are formed. At this time, the plurality of unit tanks 1 in the storage containers 2a and 2b are supported by the storage containers 2a and 2b in an arrangement that occupies an area corresponding to the shape and size of the roof of the vehicle body.
Thus, the vehicle body water cooling devices 100a and 100b are completed.

Here, since the plurality of unit tanks 1 are fixed to the bottom plate 43, the vehicle bodies 9a of various shapes and sizes can be obtained simply by changing the arrangement mode (the number and arrangement layout of the unit tanks 1). , 9b can be obtained. Further, since the unit tank 1 is a predetermined unit shape defined regardless of the shapes and sizes of the roofs 91a and 91b, it can be mass-produced relatively inexpensively, and the manufacturing cost can be effectively suppressed. it can.

<3. Usage pattern>
The usage aspect of the vehicle body water cooling device 100a, 100b will be described. Since the usage of the vehicle water cooling apparatus 100a and the usage of the vehicle water cooling apparatus 100b are the same, the usage of the vehicle water cooling apparatus 100a will be described here with reference to FIGS. 5A and 5B, and the usage of the vehicle water cooling apparatus 100b Description of is omitted.

When using the vehicle body water cooling device 100a, it is mounted on the roof 91a of the vehicle body 9a and fixed. At this time, the vehicle body water cooling device 100a is disposed such that the four operation members 222 projecting from the housing 40 of the storage container 2a are positioned on the front side or the rear side of the vehicle body 9a. In such an arrangement, the operation member 222 does not get in the way of the passenger of the vehicle. However, when the length of the operation member 222 projecting from the housing 40 of the storage container 2a is sufficiently short, the vehicle water cooling apparatus is disposed so that the operation member 222 is positioned on the left side or the right side of the vehicle body. You may

Then, in a state where the operation member 222 is inserted into the unit tank 1, water is injected from the injection port 411 provided in the housing 40 of the storage container 2 a. Then, the water injected into the case 40 flows into the insides of the cases 10 of the plurality of unit tanks 1 disposed therein via the inlets 111 and 121 (FIG. 5A). That is, here, when water is injected into the storage container 2a, the water is injected into the plurality of unit tanks 1 at a time, so that the water may be injected into each unit tank 1 only once.

Subsequently, when the user pulls out the operation member 222 inserted into the unit tank 1 by a predetermined length, the communication port 211 formed in the partition plate 21 is opened, and water leaks from the tank through hole 131 (FIG. 5B). The water leaking from the tank through hole 131 is temporarily held by the water holding member 30, and the excess water that can not be held here leaks from the container through hole 431 to the vehicle body 9a, whereby the vehicle body 9a is water cooled. Here, since the plurality of unit tanks 1 are disposed in the area corresponding to the shape and size of the roof 91a, the roof 91a can be cooled substantially equally. In addition, since the tank through hole 131 has an inverted truncated cone shape which decreases in diameter as it goes downward, the flow of water leaking from the tank through hole 131 can be made gentle, and the vehicle body 9a is gradually taken over time. Water can be supplied to Further, by providing the water retaining member 30, it is possible to supply water to the vehicle body 9a little by little over time.

In addition, when the user inserts the operation member 222 again into the unit tank 1 by a predetermined length, the communication port 211 formed in the partition plate 21 is closed, and water leakage from the tank through hole 131 is stopped ( Figure 5A). That is, the leakage of water to the vehicle body 9a stops.

In the present embodiment, since the switching means 20 is provided in each unit tank 1 of the vehicle water cooling apparatus 100a, the user independently separates leakage / non-leakage of water from each unit tank 1 provided in the vehicle water cooling apparatus 100a. Can be switched. For example, a mode of use in which water is leaked from only some unit tanks 1 to partially cool the vehicle body 9a can be used.

Second Embodiment
A vehicle coolant system according to a second embodiment of the present invention will be described with reference to FIGS. 6 to 8. Here, a water cooling system mounted on a vehicle body of a sedan type passenger car will be described as an example. Therefore, in FIG. 6 to FIG. 8, the same or corresponding components as or to those of the water cooling system 100a according to the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

The vehicle body water cooling device 500 includes four unit tanks 501 and a container 502 for accommodating them inside.

Unit tank 501 includes housing 510, switching means 20 for switching leakage / non-leakage of water from tank through hole 131 provided in bottom plate 13 of housing 510, and a water retaining member provided on the lower surface side of bottom plate 13. And 30.
