Technical Field

[0001] The utility model belongs to the technical field of heat energy recovery, in particular to an embedded heat energy recovery device. Background Art

[0002] The shell and tube heat exchanger provides a heat exchanger that can effectively realize heat exchange between gases and has the ability to compensate for temperature differences. It can prevent damage to the shell and the heat exchange tubes due to excessive temperature difference stress.
