熱効果を高めるようにしていた。Conventionally, as shown in Fig. 3, this fuel tank 1 has been covered with a double-layered heat insulating layer 3 to block the heat from the outside air, since the temperature of the liquid hydrogen 2 stored therein is extremely low at -253°C. ing. Conventionally, the fuel extraction device for the fuel tank 1 has been designed to increase the insulation effect of the tank 1 and prevent evaporation of the liquid hydrogen 2.
A pump unit 4, which has a large surface area and can easily dissipate heat from outside air into the tank, is installed near the inner bottom of the tank 1 together with a filter 5, and a drive unit 6 for driving this pump unit 4 is installed at the top of the tank l. Drive unit 6
and the pump unit 4 are connected by a rod 7 having a small surface area. If the length of this rod 7 is shortened, the heat of the outside air is easily conducted to the pump unit 4. Therefore, in the conventional device, a bulging portion 1a is provided in a part of the tank 1, and the heat from the outside air is easily transferred to the pump unit 4 by the rod 7 and the pump unit 4. The length of the rod 7 is increased by penetrating the fuel pipe 8 that leads the liquid hydrogen 2 to the outside of the tank 1 into the bulging portion 1a, thereby increasing the heat insulation effect of the tank 1.
