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 Scope
Suitable for various processes such as cooler, condensation, heating, evaporation, and waste heat recovery.
III. Categories
Tube-type cooler
Shell and Tube CoolerComposed of the external shell and the internal cooler body. Due to varying structural designs, it is categorized into pipe thread and flange connections externally; into horizontal and vertical installations; into floating disc and floating head designs; into coiled tube and finned tube structures; and into various configurations 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-type cooler enters through the inlet pipe on the cylinder, sequentially flows through each bend channel, and曲折ly reaches the outlet pipe. The cooling medium utilizes a two-pass flow, where the cooling medium enters half of the cooler tubes via the inlet cover, then flows back into the other half of the cooler tubes through the return cover and into the other side's water separator and outlet pipe. During the two-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-style Cooler
Plate heat exchangers are a new type of heat exchange equipment, featuring high heat transfer efficiency, compact structure, small footprint, and ease of installation. They can be conveniently assembled into any flow pattern to meet different process requirements, and are widely used in various industries such as petrochemical, metallurgy, machinery, light industry, food, electricity, coating, heating, and more. In recent years, they have been applied in the cooling water and pure water systems of the microelectronics industry.Ultra-pure Water SystemAlso widely adopted in China.
Due to the refrigerant fluid (cold medium) andRecirculating Cooling WaterThe working fluid does not come into direct contact; instead, the heat from the circulating cooling water is transferred to the chilled water through heat exchange plates. At this point, the circulating cooling water with higher temperature is cooled to become low-temperature fluid. When the heat transfer is isothermal on both sides of the heat exchange plates,
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 exchangers, featuring oil and air channels with heat exchange fins in the core body, offer a larger heat exchange area per volume, high heat transfer efficiency, and use air as the medium for heat exchange. Compared to water-cooled radiators, they are not only easier to install and maintain but also prevent the mixing of oil and water due to copper tube bursts, which can cause severe damage to the system. Moreover, for equipment that needs to be moved to different work locations (such as construction machinery), they do not require water supply considerations, and there is no need for disassembly and reconstruction of a water circulation system, making them increasingly popular eco-friendly products.
IV. Installation Method
Cooling unit installation methods include:Vertical Cool Oil CoolerAndHorizontal Oil CoolerVertical 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 the operation and flexibility of all drain and vent valves, as well as the switch positions. Ensure that all pressure gauges and thermometers are properly installed.
(3) Inspect the base and support for stability, and ensure that all bolts are properly and securely tightened.
(4) During operation, first introduce cold flow, then hot flow.
(5) When using cold or hot mediums, ensure the auxiliary line is clear first, then gradually open the outlet valve. After checking for any issues, open the inlet valve slowly to prevent pressure build-up. During the operation, monitor the equipment for any changes. After the cooler is in use, leaks may occur due to changes in temperature and pressure, so timely inspections are required.
