[0015] (1) This utility model has made improvements to the existing technology. In actual use, the modular tube bundle assembly solves the problem that there are significant defects in the traditional design. The welding or expansion of the tube bundle and the tube sheet is a rigid connection, which means that when a single heat exchange tube is damaged, the whole machine needs to be shut down and disassembled, resulting in a long maintenance cycle and high cost.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] According to an embodiment of the present invention, a modular connection device for a high-efficiency heat transfer tube bundle is provided, including a heat exchange mounting shell 1, a modular tube bundle assembly 2 inside the heat exchange mounting shell 1, a shell-side inlet / outlet assembly 3 on the periphery of the heat exchange mounting shell 1, and an automatic pressure relief assembly 4 on one side of the heat exchange mounting shell 1.
[0026] like Figure 1-4 As shown, according to an embodiment of the present invention, a modular connection device for a high-efficiency heat transfer tube bundle includes a tube-side inlet / outlet pipe 201. The tube-side inlet / outlet pipe 201 is symmetrically and sealed inside the heat exchange mounting housing 1. One end of the tube-side inlet / outlet pipe 201 is connected to a first connecting plate 202. A second connecting plate 203 is provided on one side of the first connecting plate 202. Bolt grooves 204 are provided around the inside of the first connecting plate 202 and the second connecting plate 203. Fixing bolts 205 are installed inside the bolt grooves 204. The second connecting plate 203 is connected to a tube bundle distribution pipe 206. A heat exchange tube bundle 207 is connected to one side of the tube bundle distribution pipe 206. A reinforcing plate 5 is connected to the periphery of the heat exchange tube bundle 207.
[0027] Through the above technical solution, the core of the modular connection device for high-efficiency heat transfer tube bundles is the modular tube bundle assembly 2. This assembly is sealed and penetrates the heat exchange mounting shell 1 through symmetrically arranged tube-side inlet and outlet pipes 201. Tube-side fluid, such as high-temperature process media, is input through the tube-side inlet and outlet pipes 201 and then diverted and guided by the docking of the first connecting plate 202 and the second connecting plate 203. The two connecting plates are fastened together by bolt grooves 204 and internal fixing bolts 205 to ensure sealing. The second connecting plate 203 is further connected to the tube bundle distribution pipe 206, which evenly distributes the fluid to multiple parallel heat exchange tube bundles 207. A reinforcing plate 5 is provided around the heat exchange tube bundles 207 to prevent tube bundle vibration and deformation, and to improve structural stability.
[0028] like Figure 1-4 As shown, according to the modular connection device of the high-efficiency heat transfer tube bundle according to the embodiment of the present utility model, the shell-side inlet and outlet assembly 3 includes a first drain pipe 301 and a second drain pipe 302. The first drain pipe 301 and the second drain pipe 302 are respectively installed on the periphery of the heat exchange mounting shell 1. Flow adjustment valves 303 are respectively installed inside the first drain pipe 301 and the second drain pipe 302. A support frame 6 is installed at the bottom of the heat exchange mounting shell 1. A controller 7 is installed on one side of the support frame 6. The flow adjustment valve 303 is electrically connected to the controller 7.
[0029] The above technical solution includes a shell-side inlet / outlet assembly 3 around the heat exchanger housing 1, used to control the circulation of shell-side fluid, such as cooling medium. This assembly comprises a first drain pipe 301 and a second drain pipe 302, located on opposite sides of the housing, enabling directional inflow and outflow of the shell-side fluid. Flow regulating valves 303 are installed inside both pipes, allowing precise control of the shell-side flow rate and velocity by adjusting the valve opening. The bottom of the device is fixed to the ground by a support frame 6, with a controller 7 installed on one side, electrically connected to the flow regulating valves 303 for remote flow control. This design ensures efficient flushing of the shell-side fluid against the outer wall of the heat exchanger tube bundle 207, maximizing heat exchange efficiency.
[0030] like Figure 1-4 As shown, according to the modular connection device of the high-efficiency heat transfer tube bundle according to the embodiment of the present utility model, the automatic pressure relief component 4 includes a pressure relief pipe 401, which is installed on the periphery of the heat exchange mounting shell 1. A pressure relief valve 402 is installed inside the pressure relief pipe 401. A temperature sensor 403 is installed inside the heat exchange mounting shell 1. A pressure sensor 404 is installed on one side of the temperature sensor 403. The pressure relief valve 402, the temperature sensor 403 and the pressure sensor 404 are electrically connected to the controller 7.
[0031] Through the above technical solution, the automatic pressure relief component 4 is integrated into the periphery of the heat exchange mounting housing 1, and consists of a pressure relief pipe 401 and a built-in pressure relief valve 402. A temperature sensor 403 and a pressure sensor 404 are installed inside the housing to monitor the shell-side operating conditions in real time. When the temperature sensor 403 detects overheating or the pressure sensor 404 detects overpressure, a signal is transmitted to the controller 7, triggering the automatic opening of the pressure relief valve 402, allowing the overpressured fluid to be safely discharged through the pressure relief pipe 401. The pressure relief valve 402, temperature sensor 403, and pressure sensor 404 are all electrically linked to the controller 7, forming a closed-loop safety protection system.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
