Product Details
I. Definition
Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as coolants to dissipate heat.
Section II: Applicability Scope
Suitable for various conditions such as coolers, condensation, heating, evaporation, and waste heat recovery.
Section 3: Categories
Tube-type cooler
Tubular coolerComposed of the outer shell and the internal cooler body. Due to different structural designs, it is divided into threaded pipe connection and flanged connection externally; into horizontal and vertical installations; into floating disk and floating head designs; into coiled tube and finned tube structures for the cooler tubes; and into various structural forms such as bow-shaped baffle plates, rectangular baffle plates, double weir baffle plates, and circular baffle plates, all selected based on specific conditions.
② Principle
The heat medium of the tube bundle cooler enters through the inlet header on the cylinder and sequentially flows through each baffle channel, winding its way to the outlet header. The cooling medium, however, utilizes a double-pipe flow, where the cooling medium enters half of the cooler tubes through the inlet water cover and then flows into the other half through the return water cover, into the other side water cover and outlet pipe. During the double-pipe flow process, the cold medium absorbs the excess heat released by the heat medium and is discharged 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 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, and are thus 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 widely adopted in China as well.
Due to the refrigerant fluid (cryogenic water) andRecirculating Cooling Water(Working fluid) does not come into direct contact; instead, heat from the circulating cooling water is transferred to the chilled water through heat exchange plates. At this point, the circulating cooling water with a higher temperature is cooled down to become low-temperature fluid. When the heat transfer between the fluids on both sides of the heat exchange plates is isothermal,
3. Air-cooled cooler
Air-cooled oil cooler (abbreviated as air cooler) is a type of cooler that uses air as the cooling source.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 with high heat transfer efficiency, and heat exchange is conducted through air. Compared to water-cooled radiators, it not only has simple installation and maintenance but also avoids the mixing of oil and water due to copper pipe bursts, which can cause severe damage to the system. Furthermore, for equipment that needs to change work locations (such as construction machinery), it does not require water supply considerations, and there is no need to disassemble and rebuild a water circulation system, making it an increasingly popular environmentally friendly product.
IV. Installation Method
Cooler installation methods include:Vertical Cold Oil CoolerAndHorizontal Oil CoolerVertical coolers feature a small required installation area and ease of 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 generators and other equipment.
CoolerPressure TestUpon qualification, the equipment may be put into use, and before operation, ensure all internal water is drained.
(2) Check the operation and flexibility of all drain and vent valves, as well as the positioning of the switches. Ensure that the pressure gauge and thermometer are fully installed.
(3) Inspect the foundation and supports for stability, and ensure all bolts are fully engaged and tightened.
(4) In use, first introduce cold flow, then hot flow.
(5) When using cold or hot media, ensure the auxiliary line is clear first, then slowly open the outlet valve. After confirming no issues, open the inlet valve slowly to prevent pressure buildup. Monitor equipment changes during the startup process. After the cooler is in use, leakage may occur due to changes in temperature and pressure, so timely inspections should be conducted.
