Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchange tube bundle for an anti-clogging tower top air cooler. Background Technology

[0002] Tower-top air coolers are commonly used cooling equipment in the petrochemical industry. Using air as the cooling medium, they are installed at the top of towers to cool oil, gas, or steam. Their core component, the heat exchange tube bundle, is covered with fins. Forced ventilation by a fan achieves heat exchange between the high-temperature medium inside the tubes and the air outside. Compared to water-cooled equipment, it saves water and energy, is easier to maintain, and has a compact structure and flexible installation. However, its cooling effect is easily affected by ambient temperature, and the fan generates noise during operation. The heat exchange tube bundle, the core component of the tower-top air cooler, is made of tubing covered with fins to increase the heat exchange area. Cooling is achieved through heat exchange between the medium inside and outside the tubes, ensuring the efficient operation of the air cooler.

[0003] Announcement No. CN220437200U discloses an anti-clogging tubular heat exchanger, including a tube body with a first flange installed on the outside of the tube body. A fixing bolt passes through one side of the first flange, and a front end cover is movably connected to one end of the fixing bolt. This anti-clogging tubular heat exchanger, through the arrangement of the front end cover, cold source outlet, heat source inlet, movable bolt, pre-filter, front baffle plate, and filter screen cover, allows for preliminary filtration of impurities in the fluid after the fluid enters through the pre-filter, reducing the impurity content and lowering the probability of clogging. Before the heat source enters the heat exchange tube through the front baffle plate after passing through the front end cover, the filter screen cover of the front baffle plate can also perform secondary filtration of impurities in the fluid, further reducing the impurities and keeping the heat source entering the heat exchange tube pure.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when filtering heat sources through a filter screen, long-term use causes impurities in the heat source to clog the filter screen, affecting the heat source's transmission efficiency.
