難である。[0002] In a space such as an orbit, when air bubbles are mixed into water circulating in an experimental device, the operation of a pump or the like is disturbed, and the experimental device may be stopped. The reason is that air trapped in the upper part of the circulatory system on the ground becomes bubbles in a zero gravity state, moves inside the device by the flow of fluid, and due to wettability and surface tension, bubbles are combined, This is because the fan, the filter, and the like cannot be separated, thereby inhibiting circulation. Further, it is difficult to remove air bubbles in the apparatus because they cannot be visually checked.

ことは困難であった。However, a device in which a perforated plate is arranged in a flow path is used by being incorporated in a device, and requires a driving device. Also, if the mass of air becomes thicker in the perforated plate, the flow of liquid may be hindered, and it has been difficult to maintain the bubble removing function in space for a long period of time.

This apparatus is installed at a water inlet / outlet of the experimental apparatus 1. A water pack 2 and an inlet connector 3 are connected to one of the cooling water interface ports of the experimental apparatus 1, and an outlet connector 5 with a syringe 4 is connected to the opposite port. The water injected from the water pack 2 enters through the inlet connector 3 and is pushed out from the outlet connector 5. The extruded water passes through the mesh filter 6, and the bubbles 7 that have come together are captured by the mesh filter 6. Air bubbles captured 7
Is removed into the syringe 4 by the needle 8 of the syringe 4. The water from which bubbles have been removed returns to the experimental apparatus 1 through the valve 9 for preventing backflow. The tube 10 and the T-tube 11 are made of a transparent material. The needle 8 of the syringe 4 sucks the air bubbles 7 of the mesh filter 6 through the seal valve 12. Stop 13
Is used to maintain the state of water.

This will be described in detail with reference to the drawings. First, water is poured into the syringe 4. Next, the syringe 4 and the needle 8 are connected. Syringe 4
The tube 10 is filled with the water therein, and when the water overflows from the outlet connector 5, the outlet connector 5 is connected to the cooling system interface port of the experimental apparatus 1. When the water in the syringe 4 has been discharged, the water pack 2 is pressurized and the air in the tube 10 is extruded. When there is no air in the tube 10 and water comes out from the inlet connector 3 , it is connected to the other cooling system interface port. In this state, the water pack 2 is further pressurized to send water into the experimental apparatus 1. The water that has come out under the supplied pressure flows through the mesh filter 6. Air bubbles are captured by the mesh filter 6. When the air bubbles accumulate to some extent, the pressurization of the water pack 2 is stopped and the stopper 13 is stopped. The needle 8 is brought close to the air bubbles captured by the mesh filter 6, the syringe 4 is pulled, and the air bubbles 7 are sucked. After the removal of air bubbles, the stopper 13 is removed and the water pack 2 is pressurized again. Repeat this operation. Before the syringe 4 is full, water is sucked and the needle 8 is filled with water. The syringe 4 and the needle 8 are disassembled to empty the syringe 4. It is connected to the needle 8 again and the operation is continued.
