DELLOK YONGHUI Air Cooler Tube Bundle
An air cooler heat exchanger consists of the following components:
· One or more bundles of heat transfer surface
· An air-moving device, such as a fan, blower, or stack.
· Unless it is nature draft, a driver and power transmission to mechanically rotate the fan or blower.
· A plenum between the bundle or bundles and the air-moving device.
· A support structure high enough to allow air to enter beneath at a reasonable rate.
· Optional header and fan maintenance walkways with ladders to grade.
· Optional lovers for process outlet temperature control.
· Optional recirculation ducts and chambers for protection against freezing or solidification of high pour point fluids in cold weather.
· Optional variable pitch fan hub for temperature control and power savings.
A tube bundle is an assembly of tubes, headers, side frames and tube supports. Usually the tube surface exposed to the passage of air has extended surface in the form of fins to compensate for the low heat transfer rate of air at atmospheric pressure and at a low enough velocity for reasonable fan pow consumption.
