Product Details
Daqing surface cooler air cooler evaporator manufacturer
A surface cooler is a key equipment used for air cooling or dehumidification in HVAC systems, which achieves temperature regulation through heat exchange between refrigerant (such as chilled water or refrigerant) and air.
1. Basic structure and working principle
structural compositionComposed of metal tubes (copper/aluminum tubes) and fins (aluminum/copper sheets), forming a high thermal conductivity heat exchange surface.
working principleThe refrigerant flows inside the tube, and air passes between the fins, completing heat exchange through conduction and convection, reducing air temperature or condensing dehumidification.
2. Main types
Classified by refrigerant：
water-cooledUsing chilled water (7-12 ℃), commonly found in air conditioning systems.
Direct Expansion (DX)Charging refrigerant (such as R22/R410A), commonly used for small units.
Classified by Function：
dry coolingOnly cooling, no condensation water.
Wet coolingCombining cooling and dehumidification, a condensate tray is required.

3. Core Features
Efficient heat exchangeFin design (such as corrugated sheets and window blades) increases contact area and improves efficiency.
Low resistanceOptimize air flow channel design to reduce fan energy consumption.
corrosion-resistantOptional anti-corrosion coating (such as epoxy resin) or hydrophilic film treatment.
4. Typical application scenarios
commercial buildingFresh air units or air conditioning units in shopping malls and office buildings.
industrial sectorTemperature and humidity control in the clean room.
special environmentPrecision air conditioning for data centers and cold chain logistics cold storage.
5. Selection and maintenance points
Selection parametersCalculate the heat transfer (kW), air volume (m ³/h), and face velocity (usually 2-3m/s).
Maintenance requirementsRegularly clean the fins (to prevent dust accumulation) and check the smooth drainage of condensed water.
