Disclosed are a method and a device for effectively restraining the generation of thermal stress when effecting slow cooling at the time of starting, etc. of a heat exchanger for heating a low temperature liquid. In a method for effecting slow cooling in a heat exchanger equipped with an inlet chamber into which a low temperature liquid is introduced, the low temperature liquid is sprinkled in the inlet chamber at a lower flow rate during slow cooling than during normal operation. A slow cooling device is equipped with a slow cooling LNG supplying means having a sprinkling means for sprinkling the low temperature liquid.

Vaporizer for a low temperature liquid

An intermediate fluid type vaporizer has an intermediate fluid evaporator for containing an intermediate fluid. The intermediate fluid evaporator includes heat source tubes for evaporating the intermediate fluid, and a low-temperature liquid evaporating section for evaporating a low-temperature liquid by exchanging heat between the low-temperature liquid and the evaporated intermediate fluid. In the intermediate fluid evaporator, members for dividing the intermediate fluid, and cover plates for covering both ends of the intermediate fluid level from above are provided to prevent the intermediate fluid level from changing due to the shaking of the intermediate fluid evaporator itself. This vaporizer and an LNG tank are mounted on a ship so as to vaporize LNG in the ship and to supply the LNG to an onshore consumer.
