<p>Provided is a cryogenic liquid vaporizer which allows an inter-vaporizing tube distribution pipe to become less likely to undergo bending deformation due to a difference in temperature of the inter-vaporizing tube distribution pipe in a longitudinal direction thereof. The vaporizer is characterized in that it comprises: a vaporizing tube panel (16) including a plurality of vaporizing tubes (21) and an inter-vaporizing tube distribution pipe (22) for distributing a cryogenic liquid to the respective vaporizing tubes (21), wherein the plurality of vaporizing tubes (21) are arranged on a vertical plane and side-by-side in a horizontal direction, and the inter-vaporizing tube distribution pipe (22) is disposed to extend in the horizontal direction and connected to respective lower ends of the vaporizing tubes (21); a liquid supply section (30) for supplying a heat-exchanging liquid from an upper end of the vaporizing tube panel (16) to allow the heat-exchanging liquid to flow down along the plurality of vaporizing tubes (21); and a heat-transfer suppressing section (23) for, with respect to a heat transfer rate from the heat-exchanging liquid to a first region (A1) of the inter-vaporizing tube distribution pipe (22) where the plurality of vaporizing tubes (21) are arranged, suppressing a heat transfer rate from the heat-exchanging liquid to an overall second region (A2) of the inter-vaporizing tube distribution pipe (22) located outside the first region (A1).</p> |
