ーブル・システムを提供することにある。As a large-capacity power transmission system, an evaporative cooling cable system using a refrigerant such as liquefied gas R-i24 is currently being developed. A typical example of the present evaporative cooling cable system will be explained using FIG. That is, the conventional evaporative cooling cable system shown in FIG. 1 is comprised of a cooling facility 1 that houses a refrigerant, and a transmission line 2 to which the refrigerant is supplied from the cooling facility 1. This power transmission path 2 includes a power transmission cable 2-1 cooled with a refrigerant, and this cable 2-1
A cable storage pipe 2- that stores the cables and communicates with the cooling equipment 1.
2. It is comprised of a refrigerant pipe 2-3 that is housed within the cable storage fifi 2-2 and communicates with the cooling equipment 1, and a partition wall 2-4 that partitions the cable storage pipe 2-2. The refrigerant is sent in liquid form from the cooling equipment 1 to the refrigerant pipe 2-3 as shown by the arrow 3-1, and after passing through the entire refrigerant pipe 2-3, it is pumped from the far end as shown by the arrow 3-2. It is released into the space inside the cable storage pipe 2-2, vaporizes while cooling the cable 2-1,
In the gas-liquid mixed state, it returns to the cooling equipment 1 as shown by arrow 3-3. In this evaporative cooling cable system, cable 2-
Since the amount of vaporization of the refrigerant changes according to the amount of heat generated by the refrigerant 1, the gas-liquid ratio inside the power transmission line 2, specifically the cable storage pipe 2-2, changes with the load (not shown). In addition, a reservoir tank (not shown) is provided in the cooling equipment 1 to compensate for the amount of change in the liquid in the cable storage pipe 2-2, but since the amount of change is large, the reservoir tank and therefore the cooling equipment 1 must be made larger. It is therefore an object of the present invention to provide a new gas-liquid separation type evaporative cooling cable system that overcomes the drawbacks of the prior art described above and allows the overall cooling equipment to be downsized.

とができる。In the gas-liquid separation type evaporative cooling cable system of the present invention,
No matter how the calorific value of the cable 2-1 changes, all vaporized gas passes through the gas-liquid separation pipe 2-5 and is transferred to the cable storage pipe 2.
-2, the inside of the gas-liquid separation tube 2-5 is always filled with liquid-phase components of the refrigerant, and the inside of the cable storage tube 2-2 is filled with abundant gas-phase components. The gas-liquid ratio of the acid line 2 as a whole is always constant, and there is no need to compensate the refrigerant supply amount according to the load. Therefore, the cooling equipment 1 only needs to liquefy the gas phase component of the refrigerant returning from the cable storage pipe 2-2 and send only the α phase component to the air separation chamber 2-5, and the reservoir tank is effectively It is unnecessary, and therefore the building in which the cooling installation is installed can be made smaller as a whole.
本発明の気液分離型蒸発冷却ケーブル・システムは以下
の顕著な効果を奏する。The gas-liquid separation type evaporative cooling cable system of the present invention has the following remarkable effects.
（１）冷却設備は、その内部に冷媒用リザーバタンクを
設ける必要はないので、建屋を小型化できる。(1) Since there is no need to provide a refrigerant reservoir tank inside the cooling equipment, the building can be made smaller.
（２ン 冷媒の気液混合状態が無いので、循環差圧を
小さくでき、ひいては送１ｌｊｌ路も小型化できる。(2) Since there is no gas-liquid mixing state of the refrigerant, the circulation differential pressure can be reduced, and the feeding path can also be made smaller.
（３）気液分離管内は液相状態にあるためＫ、循環量が
多くても圧力損が少なく、十分に小型化できるので、送
直線路内の液量を少なくできる。(3) Since the inside of the gas-liquid separation tube is in a liquid phase state, there is little pressure loss even if the amount of circulation is large, and the size can be sufficiently reduced, so the amount of liquid in the feeding line can be reduced.
（４）送電線路内にたとえ高低差があっても、冷媒の循
環設計が容易になる。(4) Even if there are height differences within the power transmission line, the refrigerant circulation design becomes easy.
（５ン ケーブル表面が常に核沸騰状態の液に覆われ
ているために、冷媒流量が零のときでも、ケーブルと冷
媒間の温度差は実質的に無視できる。(5) Because the surface of the cable is always covered with liquid in a nucleate boiling state, the temperature difference between the cable and the refrigerant can be virtually ignored even when the refrigerant flow rate is zero.
