<P>PROBLEM TO BE SOLVED: To provide a moving vessel capable of striking a balance between the improvement of a transportation capacity of a low-temperature liquefied gas and the improvement of the unloading workability of the low-temperature liquefied gas resulting from the improvement of a pressure evaporator. <P>SOLUTION: In the moving vessel 1 having a tank 10 for storing the low-temperature liquefied gas and the pressure evaporator 40 having a heat transfer tube 41 into which the low-temperature liquefied gas stored in the tank 10 is introduced, the pressure evaporator 40 is forcibly fed with gas around the heat transfer tube 41. As a result, a wind speed around the heat transfer tube 41 can be accelerated, and heat transfer between the heat transfer tube 41 and air is progressed, thus reducing thermal resistance. Accordingly, a heat transfer coefficient of the pressure evaporator 40 can be increased. By this, a capacity of the pressure evaporator 40 can be improved without enlarging the pressure evaporator 40. As a result, the improvement of the transportation capacity of the low-temperature liquefied gas and the improvement of the unloading workability of the low-temperature liquefied gas resulting from the improvement of the capacity of the pressure evaporator 40 can be made compatible. <P>COPYRIGHT: (C)2013,JPO&INPIT |
