Abstract
A heat exchanger includes a shell to which a secondary heat medium is configured to be supplied and a plate fin coil body provided in the shell. The plate fin coil body includes a plurality of plate fins and a coil which passes through the plurality of plate fins and through which a primary heat medium is configured to flow.
Claims20
A heat exchanger comprising:
- a shell to which a secondary heat medium is configured to be supplied from an outside of the shell via a closed circulation loop and from which the secondary heat medium is configured to be discharged to the outside of the shell to the closed circulation loop, the shell is an airtight sealed shell with a capacity to function as a pressure vessel in conjunction with the closed circulation loop;
- and
- a plate fin coil body provided in the shell and comprising:
- a plurality of plate fins;
- and
- a coil which passes through the plurality of plate fins and through which a primary heat medium is configured to flow,
- wherein the secondary heat medium is configured to be compressed by a compressor along the closed circulation loop and configured to be supplied to the shell as a compressed heat medium.

A heat exchanger comprising:
- a shell to which a secondary heat medium is configured to be supplied from an outside of the shell via a closed circulation loop and from which the secondary heat medium is configured to be discharged to the outside of the shell to the closed circulation loop, the shell is an airtight sealed shell with a capacity to function as a pressure vessel in conjunction with the closed circulation loop;
- and
- a plate fin coil body provided in the shell and comprising:
- a plurality of plate fins;
- and
- a coil which passes through the plurality of plate fins and through which a primary heat medium is configured to flow,
- wherein the coil includes a plurality of heat medium passages each of which includes a passage inlet via which the primary heat medium flows into the plurality of heat medium passages and each of which includes a passage outlet via which the primary heat medium flows out from the plurality of heat medium passages, and
- wherein the plurality of heat medium passages are provided such that an inlet pipe through which the primary heat medium flows into the coil is branched to the plurality of heat medium passages and such that the plurality of heat medium passages merges into the outlet pipe through which the primary heat medium flows out from the coil.
