Aluminum plate-fin heat exchanger
1 Scope
This standard specifies the requirements of design, manufacture, inspection
acceptance, installations, application and maintenance of Aluminum plate-fin heat
exchanger (hereinafter referred to as heat exchange).
1.1 This standard is applicable to the heat exchanger with design pressure no greater
than 8.0MPa. For the heat exchanger with design pressure greater than 8.0MPa, it
may be designed and manufactured with reference to this standard when the buyer is
agreed upon.
1.2 The design temperature range suitable to this standard is -269°C~200°C.
1.3 This standard is applicable to the heat exchangers applied in the situation of air
separation and liquification equipment (ASU), natural gas processing (NGP) and
liquification (LNG), petrochemical engineering and mechanical power devices.
1.4 The pressure parts of heat exchanger which couldn't be determined by this
standard, through the assessment and ratification of the National Technical
Committee on Boilers and Pressure Vessels of Standardization Administration of
China, may be designed by adopting the following methods:
a) The stress analysis (except the unit qualified for analysis design) including finite
element method;
b) Replication experimental analysis (such as experimental stress analysis and
replication hydraulic test);
c) The comparable structure which has been put into service shall be adopted to
carry out the comparison empirical design.

3.3.3 Heat transfer fin
It is the primary part of heat exchanger and the heat transfer process is mainly
finished through the heat conduction of heat transfer fin as well as the convection heat
transfer between the heat transfer fin and fluid.
3.3.4 Distributor fin
It shoulders mail the steering function for the fluid inlet and outlet, and it is generally
multi-orifice heat transfer fin.
3.3.5 Side bar
It is the primary part of heat exchanger, which are dispersed over the margins of heat
exchanger and acts to seal and support each layer of passage.
3.3.6 Parting sheet
It is the metal sheet between two layers of heat transfer fins, also called composite
sheet; it covers a layer of brazing alloy on the surface of parent metal and when it is
brazed, the alloy is melted and the heat transfer fin, side bar and sheet are welded
together.
3.3.7 Cap sheet
It is the parting sheet located at the outermost side of the heat exchanger block (core),
also called cover plate.
3.3.8 Dummy layer
It is the layer which is set on the top and bottom of the block (core) to connect with the
ambient atmosphere for heat exchange resistance according to the requirements of
strength, heat isolation and manufacture process. (And it is called the process layer).
3.3.9 Dead area
It refers to the area where the heat transfer fin or dis...
