The utility model relates to a modularized
graphene bulk curing barn
air heater capable of enhancing heat exchange, and belongs to the technical field of bulk curing barn
air heating equipment. The device comprises an air inlet
pipe, an air inlet
pipe joint, a heat preservation shell, an air outlet
pipe joint, an air supply fan, an air outlet pipe, a heating section and a mixing space, a
graphene heating module of the heating section adopts a design that
graphene heating sheets and
metal corrugated plates are arranged in a crossed manner, and the heat exchange efficiency is improved by utilizing high
thermal conductivity of graphene and strengthening convective heat exchange of the
metal corrugated plates; the mixing space strengthens air disturbance through the turbulence effect, and the
heat transfer temperature difference between air and the graphene heating sheet and the
metal corrugated plate is increased; the heat preservation shell is made of a high-temperature-resistant material and internally provided with a heat preservation rock
wool layer, and heat loss is reduced; an access door with an observation window is arranged on the side face of the heat preservation shell, and replacement of the faulted graphene heating module is facilitated through a T-shaped clamping groove and a rapid
insertion and extraction interface. The device has the advantages of enhanced heat exchange, high efficiency,
energy conservation,
modular design, easiness in maintenance and the like.
