Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a cooling container that houses electrical equipment inside and is used to prevent internal heat generation of the electrical equipment.

(Prior art) For example, as shown in Fig. 4, when a single cooling container is configured by a container body 1 and a lid plate 2, each part is cooled by flowing cooling water inside the container. things are being done.

Conventionally, cooling water channels 3 and 4 are formed independently inside each of the container body 1 and the lid plate 2, and a supply port and a discharge port are provided at the ends of each channel. Supply and discharge pipes or hoses are connected to these.

However, according to such a configuration, the container body 1,
It is necessary to prepare a supply port, a discharge port, and supply and drainage pipes connected to these ports for each cover plate 2, which is complicated.

In order to solve this problem, the flow path 3 of the container body 1 and the flow path 4 of the lid plate 2 are communicated through a connection port, thereby reducing the number of supply ports and discharge ports. This method has been separately proposed by the present inventor.

According to such a configuration, the container body 1 and the lid plate 2
It is necessary to provide a connection port on each joint surface, and specifically, it is necessary to provide a connection port on the outer periphery flange that serves as each joint surface. On the other hand, it is desirable that the width of this flange is as narrow as possible.

Therefore, as a normal configuration, as shown in FIG. 3, the connection port 5 may be elongated, that is, rectangular. The figure shows the flange 6 of the container body 1.
Although this is shown, the same applies to the connection port of the lid plate 2. Reference numeral 7 indicates a screw hole for a bolt that fastens the container body 1 and the lid plate 2.

(The problem that the invention aims to solve) However, when using a connection port with this shape,
Not only is the processing troublesome, but the flange is divided into two in the width direction over the length of the connection port 5, which is inconvenient because the mechanical strength of the flange is reduced.

This idea prevents the mechanical strength of the flange from deteriorating even when the flange is provided with a connection port for the flow of a cooling medium such as cooling water between the container body and the lid plate. , and to facilitate the processing of the connection port.

(Means for Solving the Problems) This invention is constructed by joining a container body and a lid plate, and forms a flow path through which a cooling medium flows inside each of the container body and lid plate, and Each flange that forms the joint surface between the container body and the lid plate is provided with a connection port that communicates the channels inside the container body and the lid plate, and the cooling is circulated through the channel in one of the container body and the lid plate. In the cooling container in which the medium flows to the other side through the connection port, the connection port is formed by a hole having a circular cross section, and a plurality of the connection ports are arranged in parallel along the longitudinal direction of the flange. It is characterized by what it did.

(Function) Since the connection port is formed as a hole with a circular cross section,
Its processing is easy. Moreover, since the flange is not divided into two in the width direction between the adjacent connection ports arranged in parallel, the mechanical strength of the flange does not decrease.

(Example) An example of this invention will be described with reference to FIG.
Note that parts given the same reference numerals as in FIG. 3 indicate the same or corresponding parts. Container body 1 and lid plate 2
Flow paths 3 and 4 are respectively formed inside. The container body 1 and the lid plate 2 are joined together and tightened with bolts 8, and assembled as shown in the figure. This completes one cooling container.

When assembled as described above, the lid plate 2 is placed so as to face the connection port 5 provided in the flange 6 of the container body 1 so that the flow channels 3 and 4 communicate with each other on the joint surfaces. A connection port 10 is provided on the flange 9. These structures are not particularly different from the structure shown in FIG.

According to this idea, each connection port 5, 10 is formed by a hole having a circular cross section. As shown in FIG. 2, a plurality of flanges 6, 9 are formed along the longitudinal direction. 11 is an O-ring for keeping each joint surface airtight.

For example, a cooling medium such as cooling water that has circulated in the channel 3 of the container body 1 enters the connection port 10 of the cover plate 2 through the connection port 5 as shown by the arrow in FIG.
Subsequently, it circulates within the flow path 4 of the cover plate 2. As a result, the container body 1 and the lid plate 2 are cooled.

A cooling water supply port is provided in one of the channels 3 and 4,
In addition, a discharge port is provided on the other side. Then, connect supply and drainage hoses and pipes to the supply and discharge ports. This makes it possible to reduce the number of supply ports, drain ports, and hoses and pipes for supply and drainage.

On the other hand, the connection ports 5 are holes having a circular cross section, and are formed along the longitudinal direction of the flange, so that the flange 6 is not divided into two between the connection ports 5. Moreover, these points that are not divided into two parts are located at shorter intervals than in the case of FIG.

Therefore, the mechanical strength of the flange 6 does not decrease. The same thing can be said about the flange 9 of the cover plate 2.

Since the connection ports 5 and 10 have circular cross-sections, their machining is much easier than those having a rectangular shape as shown in FIG.

(Effects of the invention) As detailed above, according to this invention, in order to reduce the number of cooling medium supply ports, discharge ports, and pipes for supply and discharge, the flanges of the container body and lid plate are When providing the connection port, there is an effect that the mechanical strength of each flange is not impaired in any way.
