Description

Technical Field

[0001] This utility model relates to the field of BFU type and cooler technology, and more specifically, to a sealing device for a BFU type cooler. Background Technology

[0002] In many industrial production processes such as chemical, power, and metallurgy, coolers are key equipment for achieving heat exchange and maintaining stable system temperature. Their performance directly affects production efficiency and product quality. The existing BFU type cooler structure is cylindrical, with a vertical or horizontal baffle inside the cylinder. The cylinder is divided into two chambers by the baffle. Each chamber has baffles that allow the oil to flow in a serpentine pattern. Multiple circulating cooling pipes are arranged along the axial direction inside the cylinder, and the circulating cooling pipes pass through the baffles.

[0003] In existing BFU-type coolers, the baffle and the inner wall of the cylinder are often connected by a slot, which results in a gap between the baffle and the slot. This causes the liquid entering the top of the baffle to flow directly into the bottom of the baffle through the gap between the second slot of the baffle. As a result, the cooling medium fails to make sufficient contact with the circulating cooling pipe, leading to a significant decrease in cooling efficiency, or even failure to achieve the expected cooling effect. Therefore, a sealing device for BFU-type coolers is proposed. Utility Model Content
