<p>PROBLEM TO BE SOLVED: To provide a tank lorry capable of improving compression performance of a compression vaporizer.SOLUTION: A fin pitch Lp on respective four straight pipes 32 forming a single meander pipe 30 is set as a following description. In detail, the fin pitch Lp=L1 on the first stage straight pipe 32 corresponding to the uppermost stream, the fin pitch Lp=L2 on the second stage straight pipe 32, the fin pitch Lp=L3 on the third stage straight pipe 32, and the fourth stage straight pipe 32 corresponding to the lowermost stream, satisfy following relationship: L4<L3<L2=L1. The configuration is for suppressing generation of frost on the meander pipe 30, and expanding a surface area of the meander pipe 30 as much as possible.</p> |
