Surface cooler

1: Full name surface cooler. The principle is to let the heat medium or refrigerant or refrigerant flow through the inner cavity of the metal pipe, and the air to be treated flows through the outer wall of the metal pipe for heat exchange to achieve the purpose of heating or cooling the air.

1:The classification of surface coolers can be divided into two categories in general

1: Snake coil type: including fan coil special type, air conditioning unit with flat type, flowing medium can be

For chilled water, hot water, industrial chilled brine, etc.

2: Fan coil type surface cooler: combined air conditioning unit, ceiling air conditioning unit, fresh air unit.

3: all kinds of oil-water cooling type surface cooler, air-cooled surface cooler, fan type surface cooler.

4: Surface cooler header material can be galvanized steel pipe, copper pipe or stainless steel pipe, surface cooler fin canbe ordinary aluminum foil or hydrophilic aluminum foil or stainless steel fin; surface cooler end plate can be galvanizedplate or stainless steel plate.

5:Φ12 andΦ 16 copper tube surface cooler fins have sine wave and arc wave plate shape two kinds. Φ9.52 Tube surface cooler sheet shape

There are two types of double sedan windows.

6: Surface cooler has 2 rows, 4 rows, 6 rows, 8 rows, 10 rows (riser).

7: The surface cooler has left and right types.

II: Installation and use of surface coolers:

1. The surface cooler shall be provided with special support, and it is not allowed to support the surface cooler with connecting pipes.

2. The water supply and return pipes of the surface cooler should have good thermal insulation measures to reduce heat loss or avoid frosting of the pipes.

3. Cold and hot water pipes * high point should be set exhaust point,* low point should be set drain pipe. When the surface cooler is not used in winter, the remaining water should be drained to avoid freezing and cracking copper pipes.
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, water-cooled dry coil copper pipe dry coil serpentine surface cooler air cooler cooling water copper aluminum radiator to customize high-quality air conditioning condenser, evaporator, surface cooler fin heat exchanger ultrasonic cleaning, water rinse, 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 cools air flowing through heat exchange fins outside the tube through air conditioning chilled water (refrigerant water) flowing inside, fan sends cooled cold air to use place for cooling, refrigerant water brings absorbed heat back to refrigeration unit from return pipe of surface cooler, water-cooled dry coil copper pipe dry coil serpentine surface cooler cooling water copper aluminum radiator radiates heat and is sent back to surface cooler to absorb heat and cool 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.
