The welded plate heat exchanger is a heat
exchange device that is sealed by welding at a certain interval by a plurality
of corrugated heat transfer plates. When the plates are assembled, the two
groups are alternately arranged, and the plates are sealed by welding. The
inside of the plates is a herringbone corrugated plate, which enables the fluid
to form a turbulent flow at a low flow rate to enhance the heat transfer
effect. The two heat exchange media flow into the respective flow channels,
forming a countercurrent or cocurrent flow through each of the plates for heat
exchange.
Features: (1) small size, small footprint;
(2) high heat transfer efficiency;
(3) low metal consumption;
(4) The heat loss is small;
(5) withstand pressure and high
temperature;
(6) The heat transfer efficiency is
slightly worse than the detachable plate heat exchanger;
(6) Compared with the detachable plate heat
exchanger, it is not detachable, and the design area is in the early stage. If
the production capacity increases or the usage increases in the later stage, it
is impossible to add the area to the heat exchanger, and only the entire
equipment can be replaced.
