A heat exchanger includes a heat exchanger body having a plurality of layer portions each having a plurality of flow paths, and having a configuration in which adjacent layer portions are joined to each other, an inflow header being configured that a fluid is introduced into the inflow header to flow into the plurality of flow paths, an outflow header being configured that a fluid flowing through the plurality of flow paths merges, a cover portion covering all joint portions of the adjacent layer portions or all joint portions of components of layer portions, the joint portions exposed on an outer surface of the heat exchanger body at a portion other than a portion where the inflow header and the outflow header are disposed, and a lead-out portion connected to the cover portion and forming an internal flow path communicating with a space between the cover portion and the heat exchanger body. The lead-out portion is configured to emit a fluid to a predetermined region set in advance.

Heat exchanger

A plate fin heat exchanger of the present invention includes a heat exchange part including a heat exchange part main body including layers of plural flow passages, and heat transfer members each of which is disposed within each flow passage of the heat exchange part main body to transfer the heat of fluid flowing in each of the flow passages to each partition walls opposed across the flow passage; and sensing parts connected to both the outsides of the heat exchange part respectively. Each of the sensing parts includes plural sealed spaces, and a sensor wall disposed to separate the outermost sealed space from the sealed space on the inner side thereof. The plate fin heat exchanger further includes a detection means for detecting damage of the sensor wall of the sensing part. According to such a structure, external leak of the fluid performing the heat exchange can be prevented while suppressing deterioration of performance or increase in size or weight.

Plate fin heat exchanger

A pressure vessel, including: a body portion; and an inclined nozzle projecting from the body portion along an axis inclined relative to an inner surface of the body portion, wherein: a through hole of a circular section is formed through both the body portion and the inclined nozzle. At an intersecting portion between the inner surface of the body portion and a surface surrounding the through hole, there are formed round portions. The radius of each of the round portions at two positions in a major axis direction is smaller than the radius of each of round portions.

Pressure vessel

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.
