Product Details
I. Definition
Coolers are a type of heat exchange equipment used to cool fluids. They typically use water or air as a coolant to dissipate heat.
Section II: Application Scope
Suitable for various processes including cooler, condensation, heating, evaporation, and waste heat recovery.
III. Categories
Tubular cooler
Tube-in-tube coolerComposed of the outer shell and the internal cooler body. Due to variations in specific structural designs, they are categorized into threaded pipe and flanged connections; horizontal and vertical installations; floating disc and floating head designs; helical tube and finned tube configurations for the cooler tubes; and various structures such as bow-shaped baffle plates, rectangular baffles, double weir baffles, and circular baffles, all selected based on specific conditions.
② Principle
The heat medium of the tube bundle cooler enters through the header on the cylinder, sequentially passing through each baffle channel, and曲折ly flows to the header outlet. The cooler medium, however, employs a two-pass flow, where the cooler medium enters through the inlet, flows into half of the cooler tubes via a water-distributing cover, and then returns to the other half of the cooler tubes through a return water cover, entering another water-distributing cover and the outlet pipe. During the two-pass flow of the cold medium, it absorbs the excess heat released by the heat medium and discharges it through the outlet, maintaining the working medium at the rated operating temperature.
2. Plate-style Cooler
Plate-type coolers are a new type of heat exchange equipment featuring high heat transfer efficiency, compact structure, small land occupation, and easy installation. They can be conveniently combined into any flow form according to different process requirements, hence widely used in various industrial fields such as petrochemical, chemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been applied in the cooling water and pure water systems of the microelectronics industry.Ultra-pure Water SystemIt is also widely adopted in China.
Due to the refrigerant fluid (cold medium) andRecirculating cooling water(Working fluid) is not in direct contact; instead, the heat from the circulating cooling water is transferred to the refrigerant water through heat exchange plates. At this point, the circulating cooling water, which is at a higher temperature, is cooled down to become a low-temperature fluid. When both fluids on either side of the heat exchange plates are at a constant temperature for heat transfer,
3. Air-cooled cooler
Air-cooled oil cooler (abbreviated as air cooler) is a type of cooler that uses air as its cooling source.Aluminum alloy plateWingShell and tube heat exchanger with oil and air channels featuring heat transfer fins, offering a larger heat exchange area per volume and high thermal efficiency, utilizing air as the medium for heat exchange. Compared to water-cooled radiators, it not only simplifies installation and maintenance but also prevents oil-water mixture due to burst copper pipes, thus avoiding severe damage to the system. Additionally, for equipment that needs to be moved to different work locations (such as construction machinery), it eliminates the need to consider water supply, and there's no need for disassembly and reconstruction of a water circulation system, making it an increasingly popular eco-friendly product.
IV. Installation Method
Cooling unit installation methods include:Vertical Cold Oil CoolerAndHorizontal Oil CoolerVertical coolers feature compact installation area and easy installation. Horizontal cool oilers have lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cool oiler based on different site conditions, space height, and performance requirements can better meet the needs of generators and other equipment.
CoolerPressure TestAfter qualification, the equipment can be put into use, and then fill the front with internal water.
(2) Check if all drain cocks and vent valves are functioning smoothly and if the switch positions are correct. Ensure that the pressure gauge and thermometer are fully installed.
(3) Inspect the base and support for stability, and ensure all bolts are fully and securely tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using chilled or heated mediums, ensure the auxiliary line is clear first, then slowly open the outlet valve. After checking for any issues, open the inlet valve, but do so slowly to prevent overpressure. Monitor the equipment's changes during the operation. After the cooler is put into use, leakage may occur with changes in temperature and pressure, so it should be checked promptly.
