Claims

[Scope of Claim for Utility Model Registration] (1) A first heat transfer tube for introducing condensed water generated in an evaporator constituting an air conditioner, a first cooling jacket provided around the first heat transfer tube,
A gasoline inlet provided at one end of the first cooling jacket, a second heat exchanger tube whose one end is connected to the other end of the first cooling jacket, and a gasoline inlet provided around the second heat exchanger tube. a second cooling jacket provided therein and into which condensed water can be freely introduced from the downstream end of the first heat exchanger tube; and a second cooling jacket provided within the second cooling jacket so as to cover the second heat exchanger tube. A gasoline cooling device consisting of a water retaining material. (2) A claim in which an excess gasoline return pipe is connected to one end of the first cooling jacket to return surplus gasoline that is not taken into the engine to the gasoline tank, and the other end of the second heat transfer tube is communicated with the gasoline tank. 1. The gasoline cooling device according to 1. (3) tilting the second heat transfer tube in a direction that becomes lower as it goes toward the first cooling jacket;
One end of the first cooling jacket is connected to the end of a steam pipe that sends gasoline vapor generated in the gasoline tank to the canister, and the other end of the second heat transfer tube is connected to the canister. 2. The gasoline cooling device according to claim 1, wherein a trap provided at the bottom communicates with the gasoline tank.
