Runner is provided for medium is logical.
As preferably, the thickness of described interlayer lead-in is 3～4 millimeters.Shell side is made to leave certain circulation path, this scope
Interlamellar spacing can produce higher heat exchange efficiency, be also avoided that sticky filter medium clogging between heat-exchanging tube bundle, resistance drop is less.
The coiled heat exchanger being provided with interlamellar spacing of the present utility model, has the advantage that
(1) setting of interlamellar spacing, it is to avoid heat-exchanging tube bundle friction between layers when heat exchanger runs, effectively prevents from changing
The leakage that heat pipe bundle causes because of shake friction, extends the service life of heat exchanger.
(2) circumference anchor ear and interlayer take advantage of bar installation simply, stable connection, convenient disassembly.
(3) interlamellar spacing can be cooled to fluid medium provide runner, it is to avoid sticky filter medium clogging heat-exchanging tube bundle it
Between, resistance drop is less, while improving heat exchange efficiency, reduces the fault rate of equipment.
