Types of air-cooled heat exchangers The primary distinction in classifying this type of equipment is based on whether the fan is upstream from the finned-tube bundle (forced draft) or downstream (induced draft)
Air-cooled heat exchangers represent a growing segment of equipment being applied in the heat transfer field. It is quite common, these days, for air-cooled heat exchangers to handle more than half the heat dissipation load in a refinery or petrdeg Chemical plant. This rapid growth has deg Ccurred because of certain advantages inherent in...
Direct Heat Exchanger is a thermal device where heat is exchanged through physical contact between two fluids—without any separating wall, tube, or plate. Unlike conventional heat exchangers, this system allows intimate mixing or direct exposure of fluids, enabling instantaneous and highly efficient thermal energy transfer. This approach is...
1.High heat transfer performance with lower back pressure. Condensation occurs inside the tube, while evaporation occurs outside.Heat transfer performance depends on the wet bulb temperature, which is generally 8-14℃ lower than the dry bulb temperature.Single-stage heat exchange. 2. Water conservation. The circulation water is only 1/5 of the...
19 Main components 1. Coil: The coil is the main heat exchange surface of the evaporative condenser. It consists of a series of horizontal tubes with fins that increase the surface area exposed to the air and enhance heat transfer. 2. Fan system: The fan system creates a draft that drives air through […]
