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. Applicable Range
Suitable for various processes such as cooling, condensation, heating, evaporation, and waste heat recovery.
III. Categories
Tubular cooler
Tubular coolerComposed of the outer shell and the internal cooler body. Due to varying structural designs, it is divided into pipe thread and flange connections externally; into horizontal and vertical installations; into floating disc and floating head types; into helical and finned tube structures for the cooler tubes; and into various structures 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 header on the cylinder, sequentially flows through each bend passage, and twists to the header outlet. The cooler medium utilizes a two-pass flow, where the medium enters half of the cooler tubes via the inlet and then flows into the other half through the return water cover, to another side water separator, and finally into the 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-type cooler
Plate heat exchangers are a new type of heat exchange equipment featuring high thermal efficiency, compact structure, small land area, and easy installation. They can be conveniently combined into any flow pattern to meet different process requirements. As a result, they are widely used in various industrial sectors including oil and gas, petrochemicals, metallurgy, machinery, light industry, food, electricity, coating, heating, and in recent years, 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 Water(Working Fluid) does not come into direct contact; they transfer heat from the circulating cooling water to the refrigerant water through heat exchange plates. At this point, the circulating cooling water with higher temperature becomes a low-temperature fluid as its temperature drops. When both fluids on either side of the heat exchange plate are at a constant temperature for heat transfer,
3. Air-cooled cooler
Air-cooled oil cooler (shortened to air cooler) is a type of cooler that uses air as its cooling source.Aluminum alloy plateWingShell-and-tube heat exchanger featuring oil and air channels with heat exchange fins, offering a larger heat exchange surface area per volume ratio and high thermal efficiency, conducting heat exchange via air. Compared to water-cooled radiators, it is not only easier to install and maintain but also prevents oil-water mixture caused by burst copper pipes, thereby avoiding severe damage to the system. Furthermore, for equipment that needs to be moved to different work locations (such as construction machinery), it eliminates the need to consider water supply, as there is no need to dismantle and reconstruct the water circulation system, making it an increasingly popular eco-friendly product.
Four: Installation Method
Cooler installation methods are categorized as:Vertical Oil CoolerAndHorizontal Cool Oil UnitVertical coolers feature a small required installation area and easy installation. Horizontal cool oilers have lower pressure drop and strong resistance to water impact. Therefore, choosing the correct 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 may be put into use, and ensure the front tank is fully filled with water.
(2) Check if all drain and vent valves are operational and easy to use, as well as the positions of the switches. Verify that the pressure gauge and thermometer are fully installed.
(3) Inspect the base and supports for stability, and ensure that all bolts are fully tightened and secured.
(4) In use, first introduce cold flow, followed by hot flow.
(5) When using cold or hot mediums, first ensure the auxiliary line is clear, then gradually open the outlet valve, check for any issues, and then open the inlet valve slowly to prevent overpressure. Monitor the equipment's changes during the startup process. After the cooler is operational, leakage may occur as temperature and pressure change, so timely inspection is required.
