Product Details
I. Definition
Coolers are a type of heat exchange equipment used to cool fluids. They typically use water or air as the cooling agent to dissipate heat.
II. Applicability Scope
Suited for various conditions including coolers, condensation, heating, evaporation, waste heat recovery, etc.
Section 3: Categories
Tube-type cooler
Tubular coolerComposed of the external shell and the internal cooler body. Due to different structural arrangements, it is categorized into pipe thread and flange connections for external connections; horizontal and vertical installations; floating disk and floating head for floating forms; helical and finned tube structures for cooler tube configurations; and various structures such as arch baffles, rectangular baffles, double-ridge baffles, and circular baffles for baffle designs, 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 twists to the header outlet. The cooling medium, however, employs a two-pass flow, where the cooling medium enters half of the cooler tubes via the inlet, then flows back through the return cover into the other half of the cooler tubes, reaching the other side of the water distributor and the outlet pipe. During the two-pass flow of the cold medium, it 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 petrochemical, chemical, metallurgy, machinery, light industry, food, power, coating, and heating. In recent years, they have been used 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 (cryogenic water) 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, which is at a higher temperature, is cooled down to become a 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 (shortened to air cooler) is a cooling unit that uses air as the cooling medium.Aluminum alloy plateWingShell-and-tube heat exchangers featuring oil and air channels with heat exchange fins, offering a larger heat exchange surface area per volume ratio and high heat transfer efficiency, utilizing air as the medium for heat exchange. Compared to water-cooled radiators, they are not only easy to install and maintain but also prevent oil-water mixture caused by burst copper pipes, thereby avoiding severe damage to the system. Additionally, for equipment that needs to be moved frequently (such as construction machinery), they do not require water supply considerations and eliminate the need for disassembly and reconstruction of water circulation systems, making them increasingly popular eco-friendly products.
Section 4: Installation Method
Cooling units come in various installation methods.Vertical Cold Oil CoolerAndHorizontal Oil CoolerThe vertical cooler features a small required installation area and easy installation. The horizontal cooler has characteristics such as lower pressure drop and strong resistance to water impact. Therefore, selecting the appropriate vertical or horizontal cooler based on different site conditions, space heights, and performance requirements can better meet the needs of generators and other equipment.
CoolerPressure TestUpon qualification, the equipment can be put into use, and the front row should be fully drained of internal water.
(2) Check if all drain cocks and vent valves are functioning smoothly and the switch positions are correct, and ensure that the pressure gauge and thermometer are all properly installed.
(3) Inspect the foundation and support for stability, and ensure all bolts are fully engaged and securely tightened.
(4) During operation, first introduce cold flow, then hot flow.
(5) When using chilled or hot media, first ensure the auxiliary line is clear, then slowly open the outlet valve. After checking for any issues, open the inlet valve, but do so slowly to prevent overpressure. Pay attention to observing changes in the equipment during the startup process. After the cooler is put into use, leaks may occur due to changes in temperature and pressure, so it is important to check them promptly.
