Function
The HX03E-22SH heat exchanger consists of two independent air recycles (internal recycle and
external recycle). The axial flow fans for the internal and external recycles support the air
convection, which implements the heat exchange through the heat exchanger between the two
recycles.
Working Principles
The HX03E-22SH heat exchanger is used to cool the sealed cabinet. The air inside the sealed
cabinet is cooled through the heat exchange with the air outside the cabinet. The axial flow fans
for the internal and external recycles support the air convection, which implements the heat
exchange through the heat exchanger between the two recycles.
Figure 10-16 illustrates the working principles of the HX03E-22SH heat exchanger.
