indicates the combined state of both. Female coupler 21. Both of the male couplers 23 are connected to the case 21-1, 23-1 and the valve body 21.
A force is applied to -2.23-2 and the valve body 21-2.23-2 in the direction of closing the liquid flow path. Spring 21-3.23-
3, and a hose 22 is connected to one end. Furthermore, an O-ring 21-4 is provided on the inner surface of the male coupler introducing portion 21-5 of the female coupler 21. Although not shown, the hoses 22 (in charge of the intra-device hoses 3 and 5 and the inter-device hoses 7, 8, etc. shown in FIG. 1) are assembled using commonly used caulking or the like to prevent leakage. To connect both couplers, connect the male coupler 23 to the male coupler introduction part 21-5 of the female coupler 21.
This is done by inserting the valve body 21-2.23-
2 move when pressed against each other, opening a flow path and allowing liquid to flow. In other words, the configuration is such that the coupler can be freely attached and detached for maintenance and repair of the device.

Note that a non-conductive liquid such as distilled water or oil is often used as the refrigerant.
上述した従来の電子装置の冷却機構では保守や修理時に
カプラを抜去した場合に作業者がカプラの結合を忘れて
電子装置を運転する場合がある。In the conventional electronic device cooling mechanism described above, when a coupler is removed during maintenance or repair, an operator may forget to connect the coupler and operate the electronic device.

する必要があった。If a non-coupled portion exists, the valve body of the coupler will be in a closed state, and the coupler will operate without any liquid flowing, leading to overheating of the heating element and having an adverse effect on the electronic device. Although a simple diagram is shown in Figure 4 for the purpose of explanation, in complex equipment, the piping system becomes complicated, and it may be impossible to require the operator to eliminate errors. It was necessary to add protection functions such as detecting the joint and preventing the device from being powered on.

It becomes possible to detect the presence or absence of a non-bonded part. In other words, even if an operator removes the coupler during adjustment or repair and forgets to insert it, it is effective in preventing the equipment from overheating by issuing a warning and preventing the power from being turned on to the equipment. Even in equipment with complicated piping, this type of operator error can be eliminated.
