A heat exchange structure includes: two flow channels stacked in a stacking direction (Y direction) and thermally coupled to each other; and a fin structure detachably installed in at least one flow channel of the two flow channels. The fin structure includes fins arranged in a longitudinal direction (Z direction) of the at least one flow channel in which the fin structure is installed, the fins configured to form openings alternately arranged along the at least one flow channel on one side and the other side of the at least one flow channel in a width direction (X direction).

Heat exchange structure

A jig for inserting a packing into a flow passage of a reactor extending in one direction or for removing the packing from the flow passage, includes: a pair of strip portions extending in parallel with each other, having a length longer than the flow passage; and link portions arranged in an extending direction of the pair of strip portions, linking the pair of strip portions and having lengths with which the pair of strip portions sandwich the packing therebetween.

Jig for inserting filling member into reactor

A reactor includes: a heat exchange section including: a first flow channel configured to flow a reaction fluid and a second flow channel configured to flow a heat medium; an introduction path for a temperature sensor, extending from an insertion opening provided on a side surface of the heat exchange section to the first flow channel or the second flow channel; a pipe for a temperature sensor, connected to a side surface of the heat exchange section and communicating with the introduction path through the insertion opening; and a jig provided in the pipe. The jig is provided with a guide hole extending from the base end toward the tip end and opened toward the insertion opening of the introduction path. The guide hole is provided with a tapered hole directed from the base end toward the tip end.
