2. Description of the Related Art In order to operate a semiconductor device, a machine tool device or the like at a desired temperature, it is necessary to remove heat generated by loss inside the device. A cooling liquid supply device using water with high water content as a cooling liquid is widely used. FIG. 6 is a cooling liquid circuit configuration diagram including a cooling liquid flow circuit of peripheral devices of the cooling liquid flow circuit of the cooling liquid supply device of such a general example.

In FIG. 6, reference numeral 9 denotes a tank 41 for temporarily storing the cooling liquid 6 which has been heated to a high temperature by cooling a cooled device 61 such as a semiconductor device, and the temperature of the cooling liquid 6 up to a desired temperature. The cooling liquid supply device includes a heat exchange device 42 that radiates heat and a total of two pumps 43 for applying a pressure for circulation to the cooling liquid 6. The cooled device 61 is composed of three divided blocks 611 in which the flow paths of the cooling liquid 6 are independent of each other. For each of the cooled blocks 611, the cooling liquid 6 having a low temperature in the cooling liquid supply device 9 is
It is supplied by the supply pipe 91 laid for each. The cooling liquid 6 that has become high temperature by removing heat from the cooled blocks 611 returns to the cooling liquid supply device 9 through the return pipes 92 laid for each of the cooled blocks 611.

The pump 43 provides the cooling liquid 6 with a pressure necessary for causing the cooling liquid 6 of a required flow rate to flow through the block 611 to be cooled. Two pumps 43 are provided in total in order to provide redundancy in order to enhance the operational reliability of the cooling liquid supply device 9. The heat exchange device 42 is provided in three sets corresponding to the supply pipes 91 laid for each of the cooled blocks 611. With the above-described devices, a supply system for each cooled block 611, which is provided with a path of the heat exchange device 42 → supply pipe 91 → cooled block 611 → return pipe 92, is independently configured. The cooling liquid 6 is branched into these supply systems to be cooled in each of the cooled blocks 611.
Will be supplied to. Each heat exchange device 42
Two unit heat exchangers 421 are provided, and these unit heat exchangers 421 are heated to a high temperature by cooling air supplied from fans 422, which are two blowers installed for each heat exchange device 42. The heat is removed from the cooling liquid 6.

The cooling liquid supply device 9 serves as pipes, such as a pipe connector 81 for connecting each supply pipe 91, a pipe connector 82 for connecting each return pipe 92, a pipe connector 82 and a tank 41. A pipe line 51 connecting between
A pipe line 52 for collecting the cooling liquid 6 from the tank 41 and branching it to two pumps 43 to allow the cooling liquid 6 to flow therethrough, and a pump 4
3 for connecting the header 3 to the header 44, and the header 4
4 and the inlet 54 of the cooling liquid 6 of each unit heat exchanger 421, and the outlet of the cooling liquid 6 of each unit heat exchanger 421 and the header 45. The outlet side pipe 55 and the supply pipe 56 for connecting the header 45 and the respective pipe connection tools 81 are provided. Here, of the outlet side pipes 55, the one connected to the outlet of the cooling liquid 6 of the unit heat exchanger 421 is the pipe 55a, and the outlet of the cooling liquid 6 of the other unit heat exchanger 421. A pipe 55b is connected to.

The header 45 is an elongated circular pipe whose both ends are watertightly closed, and the pipes 56 are attached to the side wall of the circular pipe at intervals, and belong to a certain supply system. Pipelines 55a and 55b belonging to the same supply system are mounted adjacent to each other on the side wall facing the pipeway 56. As a result, the cooling liquid 6 is supplied to the device to be cooled 61 such that the independent supply systems have the same head of water, so that the respective blocks to be cooled 611 can be operated under the same cooling conditions. It will be possible.

In the cooling liquid supply device 9 having the above-described structure, the cooling liquid 6 pressurized by the pump 43 is passed in parallel to the respective supply systems after the header 44, and the flow rate thereof is the heat exchange device 42. , The supply pipe 91, the block 611 to be cooled, the return pipe 92 or the header 45, and is mainly determined by the inverse ratio of the sum of the fluid resistances between the pipe 55a, the pipe 55b and the pipe 56, If necessary, a flow rate adjusting valve (not shown) is provided so that the flow rate of each supply system is the same, so that a desired flow rate is set. Therefore, in the header 45, the flow rate of the cooling liquid 6 flowing from the pipeline 55a belonging to a certain supply system or the pipeline 55b to the pipeline 56 belonging to another supply system is such that the inside of the header 45 has an elongated circle shape. It is composed of a pipe, and its fluid resistance value per unit length is large, so that it is extremely small.

Further, the cooling liquid supply device 9 is provided with the two pumps 43, so that even if one of the pumps 43 becomes inoperable, the cooling block 611 provided in the device to be cooled 61 is stably provided. In addition to supplying the cooling liquid 6 under the temperature condition required by, even when one of the two fans 422 provided with the two becomes inoperable,
Since the remaining one fan 422 removes heat from the cooling liquid 6, it has a function of continuously supplying the cooling liquid 6 although the temperature rises a little, and the device to be cooled 61 is cooled with high reliability. The liquid 6 can be supplied.

By the way, since the cooling liquid supply device has the above-mentioned circuit structure of the cooling liquid, a large amount of heat is generated as in the case where the object to which the cooling liquid 6 is to be supplied is a large general-purpose computer. If it is a generating device, the entire cooling liquid supply device becomes quite large. It is possible to carry out such a large-scale cooling liquid supply device transportation work to its installation location by using equipment such as an elevator already installed in the building in which the cooling liquid supply device is installed. For this reason, or in order to facilitate installation work, etc., the cooling liquid supply device is generally divided into a plurality of constituent units. As a method of dividing into a plurality of parts, taking the cooling liquid supply device 9 as an example, the tank 41 and the heat exchange device 4 are used.
2, coolant pump 43, header 44, header 4
5 and the pipelines including the pipelines 51, 52, 53, 54, 55, 56, etc., which make up the cooling liquid supply device 9 are divided into appropriate device groups, or each of them is substantially divided. It is often divided into unit cooling liquid supply devices having the same function.

FIG. 7 is a side sectional view showing a main part of a conventional cooling liquid supply apparatus divided into a plurality of constituent units described above, and FIG. 8 is a sectional view of the connecting pipe shown in FIG. It is a partially broken side view. In addition, in FIG. 7, about the code | symbol attached | subjected in FIG. 8, only the typical code | symbol was described. In FIG. 7, reference numerals 9A and 9B denote cooling liquid supply devices that are structural units installed adjacent to each other. It is assumed that the cooling liquid supply devices 9A and 9B constitute a part or all of the cooling liquid supply device 9 described above by integrating the cooling liquid supply devices 9A and 9B. Therefore, the cooling liquid supply devices 9A and 9B have the above-described configuration contents of the cooling liquid supply device 9. Reference numerals 5A and 5B are pipelines, which are pipelines 51 to 56, respectively. 98A, 9
8B is a tank 41, a heat exchange device 42, a coolant pump 4
3, various devices such as the header 44 and the header 45, and the conduit 5
A body frame for storing and mounting A, 5B, etc.

Reference numerals 99A and 99B are holding frames for holding the conduits 5A and 5B, respectively. The respective holding frames 99A and 99B are main body frames 98.
It is attached to A and 98B. The pipelines 5A and 5B are equipped with flanges 59 that are liquid-tightly attached to the ends thereof, respectively, and the center lines of the conduits 5A and 99B are concentric with each other, and the flanges 59 of the respective conduits are provided. The surfaces are held so that the distance between the surfaces is such that the connecting pipe 7 can be inserted. The flange 59 of the conduit 5A and the flange 59 of the conduit 5B are connected by the connection pipe 7.

Next, the pressure resistance that the connecting pipe 7 should have will be described for the cooling liquid supply device 9 as an example.
In the cooling liquid supply device 9 according to an example, the gauge pressure of the cooling liquid 6 on the so-called discharge side near the pipe connector 81 is assumed to be a device of approximately 100 [kPa]. The connecting pipe 7 used at this gauge pressure is required to withstand 500 [kPa], which is five times the discharge side pressure, according to regulations. On the other hand, the design safety factor is set to 2, and the connecting pipe 7 is designed to withstand 1000 [kPa].

Further, the cooling liquid supply devices 9A and 9A are attached to the flanges 59 which the ends of the pipe lines 5A and 5B respectively have.
It is necessary to allow the center positions of the two to be slightly deviated from each other or the flange surfaces to be slightly non-parallel due to dimensional errors when the B is installed on the floor. Furthermore, the fluctuation of the ambient temperature after the installation of the cooling liquid supply devices 9A and 9B, and the cooling liquid 6 due to the operation of the cooling liquid supply devices 9A and 9B.
The mutual spacing between the flange surfaces of the flange 59 increases or decreases due to the thermal expansion and thermal contraction of the pipelines 5A and 5B due to the temperature rise and so on. Therefore, the connecting pipe 7 can absorb the dimensional error and the dimensional variation of the flange 59 as described above, together with the flexibility required for facilitating the connection work, and further, the desired pressure resistance. In addition, the liquid contact portion that constitutes the connection pipe 7 must be made of a material that does not damage the cooling liquid 6. This is particularly important when the object to which the cooling liquid 6 is supplied is a device that requires water having a large specific resistance value for the cooling liquid 6.

The connecting pipe 7 has a structure in consideration of these things, and as shown in FIG. 8, it has a bellows shape in which flange-shaped portions 71a and 71b are integrally formed at both ends. Pipes 71, a plurality of reinforcing metal rings 72 fitted outside the recesses of the pipes 71, and the pipes 5
Flange 7 to be fastened with flange 59 of A and 5B
3 and 73. Each flange 73
Is provided with a plurality of screw holes 73a having the same outer diameter as the flange 59 and having a size corresponding to the through hole of the flange 59 at the same pitch diameter as the flange 59. The pipe 71 uses ethylene tetrafluoride, which is a material that does not stain the cooling liquid 6 even if the cooling liquid 6 is water or the like. The connecting pipe 7 is made of soft ethylene tetrafluoride used for the pipe 71, and also has the bellows-like shape of the pipe 71, so that it flexes very flexibly and also expands and contracts in its length direction. It is possible. Also, the metal ring 72
Holds the outer surface of the pipe 71 as a broom and connects the connecting pipe 7
In addition to giving a desired pressure resistance value, the flexibility and stretchability of the pipe line 71 are not impaired due to the configuration of being separated from each other.

Now, returning to FIG. 7, the description will be continued. Reference numeral 78 denotes the flange 73 and the flange 5 of the conduit 5A.
9 and a packing inserted between the flange 73 and the flange 59 of the conduit 5B.
Reference numeral 79 is a fastening bolt used by penetrating the through hole provided in the flange 59 and the screw hole 73a provided in the flange 73.

In order to allow the cooling liquid supply devices 9A and 9B to operate as the cooling liquid supply device 9, the cooling liquid supply devices 9A and 9B respectively have an end portion of the pipe 5A and a pipe 5B. It is necessary to allow the cooling liquid 6 to communicate with the ends of the cooling liquid 6. Therefore, when the cooling liquid supply devices 9A and 9B are installed, the end portions of the pipeline 5A and the end portions of the pipeline 5B are connected to each other using the connecting pipe 7 as described above. However, at this time, by adopting the connecting pipe 7 having flexibility as described above, even if the center positions of the ends of the conduit 5A and the conduit 5B are slightly deviated, the conduit is not hindered. It is possible to connect 5A and the conduit 5B. Further, the cooling liquid supply devices 9A and 9B
After the installation work is completed, the pipelines 5A, 5B may be changed by changing the ambient temperature or operating the cooling liquid supply devices 9A, 9B.
Even if the connecting pipe 7 expands or contracts, the flexibility / stretchability of the connecting pipe 7 absorbs it, and even if the connecting pipes 5A and 5B expand or contract, no large stress is generated.
This makes it possible to stably maintain the communication state between A and the conduit 5B.

[0017]

In the cooling liquid supply device divided into a plurality of constituent units according to the above-mentioned prior art, the installation work can be facilitated and the conduits 5A and 5B can be expanded and contracted. Even if it does, it is possible to maintain the communication state stably, but the following problems still remain. That is, the connecting pipe 7 is extremely expensive because the structure for providing the connecting pipe 7 with pressure resistance as well as flexibility and stretchability is complicated.

When the connecting pipe 7 is attached to the pipes 5A and 5B, it is necessary to attach it to the two flanges 59 provided on the pipes 5A and 5B, respectively. The working time is long. The present invention has been made in view of the above-mentioned problems of the conventional technology, and an object thereof is to use a cheap connecting pipe and to reduce a fastening work time thereof. To provide.

[0019]

The above-mentioned objects of the present invention are as follows: 1) A device for supplying a cooling liquid, which circulates the cooling liquid to a heat exchange device for radiating the temperature of the cooling liquid to a desired temperature. A pump device for applying a pressure for use, and a connecting conduit for connecting between a heat exchange device, a pump device, etc., and the above-mentioned devices and conduits are divided into a plurality of structural units. In the cooling liquid supply device in which the end portions of the conduits of the respective constituent units such as the above are connected by a connecting pipe having flexibility, the connecting pipe has a pressure resistance corresponding to the discharge pressure of the pump device. It is a hose that is provided, and the ends of the conduits of the constituent units that are adjacent to each other are connected to the connecting pipe, and the center lines of the ends are arranged at a relational position where they intersect each other at an angle of more than 0 degrees and less than 180 degrees. And both pipes at this end The radius dimensions of the circles that are inscribed in the respective center lines of the passages are at least set to a dimension value that does not cause buckling of the connecting pipe, and 2) a device that supplies a cooling liquid. There is a heat exchange device that radiates the temperature of the cooling liquid to a desired temperature, a pump device that applies a circulating pressure to the cooling liquid, and a connection pipe that connects the heat exchange device and the pump device. A connecting pipe having the above-mentioned devices and pipelines divided into a plurality of constituent units, and having flexibility between the end portions of the pipelines respectively possessed by these constituent units adjacent to each other. In the cooling liquid supply device, the connecting pipe is a hose having a pressure resistance corresponding to the discharge pressure of the pump device, and the side connected to the connecting pipe of the pipe line of each adjacent constituent unit. End of the same direction Moreover, the center lines thereof are arranged in parallel with each other, and the distance between the center lines of the respective conduits is set to at least a dimension value that does not cause buckling of the connecting pipe. 3) In the means described in 1 or 2 above, the connecting pipe is connected to the end of the conduit of one constituent unit by a connecting means that is fixedly fastened, and the other constitution. This is achieved by a configuration in which the end portion of the conduit of the unit is connected to the end portion of the conduit by connecting means that can release the fastening.

[0020]

According to the present invention, in the cooling liquid supply device divided into a plurality of constituent units, (1) the connecting pipes are hoses having pressure resistance corresponding to the discharge pressure of the pump device and are adjacent to each other. The end on the side that is connected to the connection pipe of the pipeline that each structural unit has,
The centers of the circles are arranged in relational positions intersecting each other at an angle of more than 0 degree and less than 180 degrees, and the radius dimension of a circle inscribed at both ends of the respective center lines of both pipes is at least The dimensions are set so that the connecting pipes will not buckle, or they are arranged in the same direction and in such a relation that their center lines are parallel to each other, and the center lines of the respective pipe lines The interval dimension of is set at least to a dimension value that does not cause buckling of the connecting pipe, so that the pipe line of the cooling liquid supply device divided into a plurality of structural units has Even if the center line of the part is displaced or the end part expands or contracts due to temperature change, etc., the deformation given to the connecting pipe due to the above-mentioned arrangement provided at the end part of the conduit causes the connecting pipe to expand or contract. Then Ku, the deformation degree of bend of the connection pipe is changed.

By the way, when a hose is used as the connecting pipe, it should be noted that when the connecting pipe is repeatedly deformed in the direction of expanding and contracting the connecting pipe, the connecting pipe and a hose connecting tool such as a hose nipple. The connection between the and will gradually deteriorate and eventually cause liquid leakage at this location. If the connecting pipe is excessively deformed in the direction of compressing the length of the connecting pipe, the pipe wall of the connecting pipe will buckle, and the flow area of the connecting pipe will be greatly reduced at this buckling point. Therefore, it becomes impossible to maintain the specified flow rate of the cooling liquid. However, in the cooling liquid supply device according to the present invention, the deformation for expanding and contracting the connecting pipe does not occur due to the above-mentioned point. Moreover, since the connecting pipe can be bent with a bending radius that does not cause buckling, a hose is used for the connecting pipe that connects the cooling liquid supply device pipes that are divided into multiple constituent units. It becomes possible to do. Further, (2) the connecting pipe is connected to the end of the pipe line of one of the constituent units by a connecting means that is fixedly fastened, and the fastening is released from the end of the pipe line of the other structural unit. By being configured to be connected by a connecting means that is free,
When fastening the connecting pipe for forming the flow passage that connects the pipes with each other by the connecting pipe, the attachment work of the connecting pipe to the end of the pipe is connected by the connecting means that can release the fastening freely. It is possible to perform only the fastening work with the end of the pipeline of the other constituent unit.
