Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as the cooling agent to dissipate heat.
Section II: Applicability Scope
Suitable for various processes such as cooling, condensation, heating, evaporation, and waste heat recovery.

Tubular cooler
Shell and Tube CoolerComposed of the external shell and the internal cooler body. Due to variations in specific structural designs, they are divided into pipe thread and flange connection types externally; into horizontal and vertical installation types; into floating disc and floating head floating types; into coiled tube and finned tube cooler tube structures; and into various structural forms such as arch baffles, 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 baffled channel, and曲折ly flowing to the header outlet. The cooler medium, however, utilizes a double-pass flow, where the cooler medium enters through the inlet and flows into half of the cooler tubes via a water distribution cover, then returns through the return water cover into the other half of the cooler tubes, entering the other side water distribution cover and outlet pipe. During the double-pass flow, the cold medium 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 Cooler
Plate-type coolers are a new type of heat exchange equipment with 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. Therefore, they are widely used in various industrial fields such as petrochemicals, metallurgy, machinery, light industry, food, electricity, coating, heating, and in recent years, cooling water and pure water in the microelectronics industry.Ultra-pure Water SystemAlso widely adopted in China.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling Water(Working fluid) does not come into direct contact; they transfer heat from the circulating cooling water to the chilled water through heat exchange plates. At this point, the circulating cooling water with higher temperature is cooled down to become low-temperature fluid. When the fluids on both sides of the heat exchange plates are at a constant temperature for heat transfer,
3. Air-cooled cooler
Air-cooled oil cooler (also known as an air cooler) is a cooling device that uses air as its cooling medium.Aluminum alloy plateWingShell-and-tube heat exchanger, featuring oil and air channels with heat exchange fins in the core body, offering a larger heat exchange area per volume and high heat transfer efficiency, utilizing air as the medium for heat exchange. Compared to water-cooled radiators, it not only simplifies installation and maintenance but also prevents the mixing of oil and water caused by bursting copper pipes, which can severely damage the system. Moreover, 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 the water circulation system, making it an increasingly popular environmentally friendly product.
IV. Installation Method
Cooler installation methods include:Vertical Cold Oil CoolerAndHorizontal Cold Oil CoolerThe vertical cooler features a small required installation area and ease of installation. The horizontal cooler has lower pressure drop and strong resistance to water impact. Therefore, selecting the vertical or horizontal cooler correctly based on different site requirements, space height, and performance needs can better meet the needs of power generation sets and other equipment.
CoolerPressure TestUpon qualification, the equipment may be put into use, and all internal water should be drained before operation.
(2) Check if all drain and vent valves are functioning smoothly and properly, and ensure the pressure gauge and thermometer are fully installed.
(3) Inspect the foundation and support for stability, and ensure all bolts are fully engaged and securely tightened.
(4) When in use, first introduce cold flow, followed by hot flow.
(5) When using cold or hot media, ensure the auxiliary line is clear first, then slowly open the outlet valve. After confirming there are no issues, open the inlet valve and do so gradually to prevent pressure buildup. Pay attention to observing any changes in the equipment during the operation. After the cooler is put into use, leakage may occur due to changes in temperature and pressure, so it should be checked promptly.
