Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-Figure 3 , a heat exchanger core assembly shown in the figure includes a heat exchanger core, the heat exchanger core is composed of a plurality of tube bundles 102 arranged between two tube sheets 101, each tube bundle 102 is arranged on the side wall between the two tube sheets 101 with a plurality of baffles 103 arranged alternately, and also includes a connection mechanism arranged on one of the two tube sheets 101 for connecting the partition plate;

[0023] It should be noted here that: through the setting of the connecting mechanism, utilizing the connecting function of the connecting groove 202 and the limiting function of the limiting assembly, one end of the partition plate is connected and limited, thereby ensuring the convenience of installation of the partition plate while improving the strength of the installation connection of the partition plate, avoiding large vibrations and uneven force caused by the impact of the fluid, thereby reducing the fatigue and wear of the partition plate during use, and ensuring the normal service life of the partition plate.

[0024] It is worth noting that the specific structure and working principle of the heat exchanger and its core assembly have been mastered by those skilled in the art and will not be elaborated here.

[0025] See also Figure 2 The extrusion assembly shown in the figure includes an extrusion tube 301 fixedly connected to the bottom wall of the connection groove 202, an extrusion rod 302 is slidably connected to the extrusion tube 301, one end of the extrusion rod 302 is connected to the sealing plate 203, one end of the extrusion rod 302 located inside the extrusion tube 301 is fixedly connected to the extrusion plate 303, the other side of the extrusion plate 303 is fixedly connected to the extrusion spring 304, and the other end of the extrusion spring 304 is connected to the bottom wall of the extrusion tube 301;

[0026] It should be noted here that: by setting the extrusion assembly, the sealing plate 203 is pushed against the end surface of the step partition, thereby ensuring the sealing of the step partition during the connection and limiting process.

[0027] See also Figure 2 , there are multiple extrusion assemblies in the figure, and each extrusion assembly is arranged at an equal distance;

[0028] It should be noted here that: by setting up multiple extrusion components, a better balanced extrusion force is provided for the partition plate.

[0029] Working principle: When the tube box is connected to the shell, the partition plate will be driven to move close to the tube plate 101 synchronously. When one end of the partition plate is inserted into the connection groove 202 on the connection plate 201, the connection function of the connection groove 202 and the limiting function of the limiting assembly will limit the connection of one end of the partition plate, thereby ensuring the convenience of installation of the partition plate and improving the strength of the installation connection of the partition plate, avoiding large vibration and uneven force caused by the impact of the fluid, thereby reducing the fatigue and wear of the partition plate during use and ensuring the normal service life of the partition plate;

[0030] When the partition plate is inserted into the connection groove 202, the sealing plate 203 will be pushed, so that under the elastic action of the extrusion component, the sealing plate 203 will be pushed against the end face of the partition plate, thereby ensuring the sealing of the partition plate during the connection limiting process.

[0033] It should be noted here that: through the setting of the limit assembly, when one end of the partition plate is inserted into the connecting groove 202, when the end face of the partition plate abuts against the side wall of the limit rod 403, under the interaction force of the fillet 404 and the guiding action of the limit hole 401, the limit rod 403 is pushed to shrink into the limit hole 401, and as the partition plate continues to move into the connecting groove 202, when the partition plate moves into place, under the elastic action of the telescopic assembly, the limit rod 403 is pushed against the side wall of the partition plate, thereby realizing the installation limit of the partition plate through the tightening action of the limit rod 403.
