Surface cooler is the heat exchanger of fan coil, its performance determines the capacity of fan coil to deliver cold (heat) and the impact on air volume. It's usually found in air conditioners.
The aluminum fins of the air cooler in the air conditioner adopt the shape of a double-edged louver to ensure the disturbance of air heat exchange and make it in a turbulent state, thus greatly improving the heat exchange efficiency. The aluminum fins of the surface cooler go through strict three-way cleaning procedures in the factory, metal cleaning agent, customized surface cooler according to the drawings, ultrasonic cleaning, water rinsing, to ensure that there is no residue on the fins, so that the air flows more smoothly, fundamentally ensuring the reliability of heat exchange.
The role of surface cooler:                                         
The refrigerant absorbs heat in the surface cooler, so that the temperature of the cooled space is gradually reduced.
Fan coil surface cooler of air treatment unit, cooling air flowing through external heat exchange fins through air conditioning chilled water (refrigerant water) flowing inside, hydrophilic aluminum foil fin copper tube surface cooler surface air cooler antifreeze surface cooler satisfactory payment fan sends cooled cold air to the place of use for cooling, refrigerant water from the return pipe of the surface cooler will absorb heat back to the refrigeration unit, release heat, cool down and then be sent back to the surface cooler to absorb heat, cool the air flowing through, It's a loop.
 Generally, finned air heat exchangers with chilled water as the medium are called surface coolers, and Φ 16 copper pipes (hole pitch 38 column pitch 33) are used. In recent years Φ 12.7 copper tube (hole pitch 31.75, row pitch 27.5) surface cooler has also been widely used.
The surface cooler is manufactured by mechanical expansion technology, which ensures the heat exchange performance.
   The material of the surface cooler header pipe can be galvanized pipe, copper pipe or stainless steel pipe; the surface cooler fin can be ordinary aluminum foil or hydrophilic aluminum foil; and the surface cooler end guard plate can be galvanized plate or stainless steel plate.
According to the parameters provided by customers, such as air volume, inlet air condition, shape size, chilled water inlet temperature, cooling capacity (or outlet air condition requirements), etc., the surface cooler can be calculated and designed, and the responsibility for thermal performance indicators of the surface cooler can be assumed.
