Technical Field

[0001] The utility model relates to the field of graphite heat exchangers, in particular to a composite graphite heat exchange device. Background Art

[0002] Graphite heat exchanger is a heat exchanger whose heat transfer components are made of graphite. The graphite used to make heat exchangers should be impermeable, and impregnated impermeable graphite and pressed impermeable graphite are commonly used. Graphite heat exchangers can be divided into three types according to their structure: block hole type, shell and tube type, and plate type.
