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.
II. Applicability Range
Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.

Tubular cooler
Shell and Tube CoolerComposed of the outer shell and the inner cooler body. Depending on the specific structural method, it is divided into pipe threaded and flanged connections externally; into horizontal and vertical installations; into floating disc and floating head designs; into coiled tube and finned tube structures for the cooler tubes; and into various structures such as bow-shaped baffle plates, rectangular baffle plates, double-ridge baffle plates, and circular baffle plates, all selected based on specific conditions.
② Principle
The heat medium of the tube-type cooler enters through the inlet connection on the cylinder, sequentially flows through each曲折channel, and curves to the outlet connection. The cooling medium utilizes a two-pass flow system, where the cooling medium enters half of the cooler tubes through the inlet and then flows into the other half through the return water cover, into the other side of the water distribution 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 exhausts it through the outlet, maintaining the rated working temperature of the working medium.
2. Plate-type cooler
Plate heat exchangers are a new type of heat exchange equipment featuring high heat transfer efficiency, compact structure, small footprint, and easy installation. They can be conveniently combined into any flow pattern to meet different process requirements, thus being widely used in various industrial sectors such as petrochemicals, metallurgy, machinery, light industry, food, electricity, coating, and heating. In recent years, they have also 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 WaterThe 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 a higher temperature is cooled down to become a low-temperature fluid. When the fluids on both sides of the heat exchange plate are at a constant temperature for heat transfer,
3. Air-cooled cooler
Air-cooled oil cooler (also known as an air cooler) is a type of cooler that uses air as its cooling medium.Aluminum alloy plateWingShell-and-tube heat exchangers, featuring oil and air channels with heat transfer fins in the core, offer a larger heat exchange area per volume and high thermal efficiency, conducting heat exchange through air. Compared to water-cooled radiators, they are not only easy to install and maintain but also prevent oil-water mixing caused by bursting copper pipes, which can severely damage the system. Furthermore, for equipment that requires relocation (such as construction machinery), they eliminate the need for water supply and the disassembly and reconstruction of a water circulation system, making them increasingly popular eco-friendly products.
IV. Installation Method
Cooling system installation methods include:Vertical Cold Oil CoolerAndHorizontal Cool Oil ExchangerVertical coolers feature a small required installation area and easy installation. Horizontal cool oilers have characteristics such as 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 generator sets and other equipment.
CoolerPressure TestUpon qualification, the equipment can be put into use, and all internal water should be drained before operation.
(2) Check if all drain cocks and vent valves are operable and the switch positions are correct, as well as whether 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 mediums, ensure the auxiliary line is clear first, then gradually open the outlet valve. After confirming there are no issues, open the inlet valve slowly to prevent pressure build-up. Monitor the equipment for any changes during the startup process. After the cooler is in use, leaks may occur due to changes in temperature and pressure, so timely inspections should be conducted.
