Foreign trade export-type surface air cooler radiator hot water heater copper tube cooling fin water coil aluminum foil

Product Name:Surface cooler

Details:

The fins of the cooler are double-folded louvers, which ensure the interference of air heat exchange and make it in a flowing state, greatly improving the cooling and heating efficiency. There are three strict cleaning procedures at the factory for the aluminum fins of the surfacer. Metal cleaning agent, ultrasonic cleaning agent, clean with water, ensure that there is no residue on the fins, so that the air flow is more smooth, fundamentally ensure the reliability of heat transfer.

The surface cooler radiates heat to the refrigerant and outdoors. The compressor compresses and discharges the gas inside the body into a low temperature and high pressure liquid. Refrigerant is used to absorb heat in the surface cooler, and the temperature of the cooling space is gradually reduced by aluminum foil. The surface cooler cools the air outside the fins by the flow of internal refrigerant water, and then transports it to the place of use. The unit surface cooler refrigerant water absorbs heat and brings it back to the main engine, releases cooling water and heat, and then flows into the surface cooler to absorb heat for cooling. Air, continuous circulation.

The difference between evaporator and surface cooler

The media entering the surface cooler are usually hot water and cold water or brine.

The medium entering the evaporator is refrigerant refrigerant such as R22, 410, 407.
 

When it comes to heat exchange equipment, what do you think of? Most people think of industrial radiators, finned radiators, etc. The full name of surface cooler is surface cooler, which is also heated and cooled by heat exchange. So, the same is the effect of heat exchange, what is the difference between the two? Let's go and have a look together.

Difference between surface cooler and finned radiator: surface cooler is the flow of chilled water in the coil, and heat exchange is realized when the air passes through it. The finned radiator is a direct contact between frozen water and air in the form of fine hole spray, which plays a role in cooling and humidifying.

 1, fin radiator is mainly composed of three rows of parallel spiral fin bundle flowing between the air flow direction. The processing technology of SRZ fin tube bundle is mechanical winding method of winding 0.5*10mm reverse steel strip on 18mm seamless steel tube. Foreign trade export type surface cooler radiator hot water heater with copper pipe cooling fins water coil aluminum foil Then, you can also use hot dip galvanizing, stainless steel pipes and stainless steel belts to make all stainless steel heat dissipation. SRL radiator is a finned radiator, which is made of steel pipe and aluminum strip. Its heat dissipation area per unit length is larger than SRZ radiator.

Due to the mechanical winding of the fin heat exchanger, the contact surface between the radiating fin and the radiating tube is large and close, the heat transfer performance is good, the ventilation resistance is small, the steam or hot water flows through the steel pipe, and the heat passes through the steel pipe. The upper fins pass through the fins to the air to heat and cool it.

2, for an air conditioning box, the surface cooler is the cold coil, the main role is cooling and dehumidification. Generally divided into two rows of tubes, four rows of tubes and six rows of tubes, the air passes through the surface of the surface cooler coil, and heat exchange occurs with the surface of the low temperature surface cooler to reduce the temperature. In this process, the moisture content in the air is getting larger and larger. After reaching the dew point temperature, the partial pressure of water vapor in the air exceeds the saturation partial pressure, and dew condensation will occur on the surface of the coil, thus achieving the dehumidification effect of the surface cooler.

The principle of both is the same, the structure is basically similar, but the fin type has many fins. The fin type is mainly to add a lot of fins for increasing the heat dissipation area on the tubes of the surface cooler. The heat transfer effect is of course much higher than that of a pure surface cooler.

The above is the difference between the surface cooler and the fin radiator. When you distinguish, you can refer to the above content. If you need fin radiator, or interested in it, welcome to call our hotline for consultation, we will provide you with excellent performance equipment, will meet your needs.

1. Is the copper fin layer of the surface cooler the same as that of the traditional surface cooler?

Copper and aluminum surface cooler, its purchase considerations are detailed product parameters, current prices and quotations, origin, quality, after-sales service and manufacturers. Aluminum surface coolers and traditional surface coolers, the two considerations are the same, there is no difference.

2. Comparison of copper aluminum surface cooler and fin surface cooler

Copper aluminum surface cooler is a kind of surface cooler. It's the flow of frozen water in the coil. When the air passes through, heat exchange can be realized, and the ice radiator directly contacts the air through the fine hole injection, playing the role of cooling and humidifying. There are different things that they cannot compare.

3. How to get heat sink in copper aluminum cooler?

Fins from fins on copper and aluminum fin surfaces are produced by special pressing and stamping devices. Specifically, fins are stamped into a desired size and shape of material, and then the fins are pierced and embroidered to provide a copper aluminum surface cooler.

4. Is the surface cleaner in the air conditioner a copper aluminum surface cooler?

The surface cooler used for air conditioning is usually made of aluminum fins, so it is not a cooler on a copper aluminum surface. The heat transfer efficiency of the surface cooler is improved.
