AI Technical Summary
Traditional shell-and-tube heat exchangers are prone to localized wear, increased vibration, and decreased heat exchange efficiency when subjected to fluid impact. They are also inconvenient to maintain and lack effective pre-buffering design, which affects equipment stability and lifespan.
The structure employs convex baffles, radial partitions, and fixing rings, combined with the two bends in the cold fluid inlet pipe and seamless steel pipe material, to achieve radial dispersion and uniform diffusion of the fluid, reduce impact intensity, and facilitate maintenance through a detachable design.
It effectively reduces local impact pressure, improves equipment operation stability and lifespan, facilitates maintenance, and enhances fluid distribution uniformity and heat exchange efficiency.

Abstract
Claims
1. A novel anti-impingement structure of a shell-and-tube heat exchanger, comprising a shell (1), characterized in that: The front end of the housing (1) is connected to a head (2) by flange bolts. The head (2) has an anti-impact component inside it by a threaded assembly. The anti-impact component includes a convex baffle (10) and a fixing ring (12). The convex baffle (10) has a forward-facing convex surface and multiple partitions (11) are fixedly connected to the convex surface. The partitions (11) are arranged from the center of the convex surface of the convex baffle (10) outwards. The outer front end of each partition (11) is fixedly connected to the inner wall of the fixing ring (12). Four connecting blocks (13) are fixedly connected to the circumferential surface of the fixing ring (12).
2. A novel anti-impingement structure for a shell-and-tube heat exchanger according to claim 1, characterized in that: The front end surface of the end cap (2) is provided with a cold fluid inlet pipe (4), and the cold fluid inlet pipe (4) has two bends.
3. A novel anti-impingement structure of a shell-and-tube heat exchanger according to claim 1, characterized in that: The rear end of the housing (1) is connected to a sealing tail (3) by flange bolts, and a cold fluid outlet pipe (5) is provided on the rear surface of the sealing tail (3).
4. A novel anti-impingement structure of a shell-and-tube heat exchanger according to claim 1, characterized in that: A hot fluid inlet pipe (6) is provided on the front side of the upper surface of the housing (1), and a hot fluid outlet pipe (7) is provided on the rear side of the upper surface of the housing (1).
5. A novel anti-impingement structure of a shell-and-tube heat exchanger according to claim 1, characterized in that: Two support frames (16) are symmetrically fixedly installed on the lower surface of the housing (1).
6. A novel anti-impingement structure of a shell-and-tube heat exchanger according to claim 1, characterized in that: The threaded assembly includes four threaded holes (9), which are evenly distributed on the circumferential surface of the end cap (2). Each of the four connecting blocks (13) has a threaded hole (14) on its surface close to the end cap (2). The threaded holes (9) and the threaded holes (14) correspond to each other and have the same diameter. The inner wall of the threaded hole (9) is threadedly connected to the threaded hole (14) of the connecting block (13) by a fixing bolt (8).
7. A novel anti-impingement structure of a shell-and-tube heat exchanger according to claim 1, characterized in that: The inner wall surface of the end cap (2) is uniformly fixed with four L-shaped fixing blocks (15), and the L-shaped fixing blocks (15) are respectively corresponding to the threaded hole (9) and are set on the front side of the threaded hole (9).
8. A novel anti-impact structure for a shell-and-tube heat exchanger according to claim 1, characterized in that: The convex baffle (10) has several through holes on its surface.
