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.

[0030] Example 1;

[0031] Please see Figures 1-3 This utility model discloses a duplex plate heat exchanger that can improve heat exchange efficiency, comprising a fixed base 1, a heat exchanger body 5 fixedly installed on the top of the fixed base 1, a shell 7 fixedly connected to both sides of the heat exchanger body 5, an adjusting shell 8 fixedly connected to the top of the shell 7, a motor 16 fixedly installed on the right side of the inner cavity of the adjusting shell 8, a positive and negative threaded rod 14 fixedly connected to the left side of the motor 16, threaded sleeves 17 threadedly connected to both ends of the center of the surface of the positive and negative threaded rod 14, a connecting rod 13 fixedly connected to the bottom of the threaded sleeve 17, a baffle 11 fixedly connected to the bottom of the connecting rod 13 through the inner cavity of the shell 7, water pipes 12 fixedly connected to both ends of both sides of the heat exchanger body 5, the inner surface of the baffle 11 adhering to the outer surface of the water pipe 12, and an opening 6 on the surface of the shell 7.

[0032] Through the above technical solution, the motor 16 facilitates the rotation of the positive and negative threaded rod 14. Since the threads at both ends of the positive and negative threaded rod 14 are in opposite directions, and the threads on the surface of the positive and negative threaded rod 14 are threadedly connected to the threads in the inner cavity of the threaded sleeve 17, when the positive and negative threaded rod 14 rotates, it drives the two threaded sleeves 17 on the surface to move outward relative to each other. Through the threaded sleeves 17, it drives the connecting rod 13, and through the connecting rod 13, it drives the baffle 11 to move. This can effectively control the water flow rate of the water pipe 12, greatly improve the heat exchange efficiency of the heat exchanger body 5, and solve the problem of inconvenience for the staff.

[0033] Example 2;

[0034] like Figure 1 and Figure 4 As shown, electric push rods 19 are fixedly connected to both sides of the top of the fixed base 1. Push plate 18 is fixedly connected to the bottom of the electric push rod 19. Limiting rods 2 are fixedly connected to both sides of the top of the push plate 18. The top of the limiting rod 2 extends through to the outside of the fixed base 1 and is fixedly connected to a limiting plate 3. A mounting block 4 is inserted into the bottom of the limiting plate 3. One side of the mounting block 4 is fixedly connected to the side of the heat exchanger body 5.

[0035] Through the above technical solution, the electric push rod 19 facilitates the retraction and movement of the push plate 18, which in turn causes the push plate 18 to retract and move the limit rod 2. The limit rod 2 then pushes the limit plate 3 to move. As the limit plate 3 moves, it disengages from the groove on the surface of the mounting block 4, making it easier to release the limit on the heat exchanger body 5. This facilitates disassembly, maintenance, and cleaning, greatly improving the utilization efficiency of the heat exchanger body 5 and indirectly improving its heat exchange efficiency.

[0036] Example 3;

[0037] like Figures 1-4 As shown, the surface of the mounting block 4 has a groove, the bottom of the limiting plate 3 is inserted into the inner cavity of the groove, the bottom of the fixing seat 1 is fixedly connected to the four sides of the bottom, and the bottom of the fixing column is fixedly connected to the anti-slip pad, the bottom of the inner cavity of the housing 7 has a limiting groove 10 on both sides, the bottom of the baffle 11 is fixedly connected to the slide rod 9, and the bottom of the slide rod 9 is slidably connected to the inner cavity of the limiting groove 10, the top of the inner cavity of the adjusting shell 8 has a sliding groove on both sides, the top of the threaded sleeve 17 is fixedly connected to the slider 15, and the top of the slider 15 is slidably connected to the inner cavity of the sliding groove, the left side of the inner cavity of the adjusting shell 8 is fixedly connected to the bearing, and the left side of the positive and negative threaded rod 14 is rotatably connected to the inner cavity of the bearing.

[0038] Through the above technical solution, the sliding rod 9 can slide in its inner cavity through the limiting groove 10, which improves the sliding stability of the baffle 11. The sliding groove allows the slider 15 to slide in its inner cavity, which improves the sliding stability of the threaded sleeve 17.

[0039] The working principle of this utility model is as follows: First, when the pressure drop of the heat exchanger body 5 is permissible, the user starts the motor 16 to rotate forward via an external controller. The motor 16 has forward and reverse rotation functions. The forward rotation of the motor 16 facilitates the rotation of the positive and negative threaded rods 14. Since the threads at both ends of the positive and negative threaded rods 14 are in opposite directions, and the threads on the surface of the positive and negative threaded rods 14 are threadedly connected to the threads in the inner cavity of the threaded sleeves 17, when the positive and negative threaded rods 14 rotate, they drive the two threaded sleeves 17 on the surface to move outward relative to each other. Through the threaded sleeves 17, the connecting rod 13 is driven, and through the connecting rod 13, the baffle 11 is driven to move, which can effectively control the water pipe 1. The increased inlet and outlet water flow rates significantly improve the heat exchange efficiency of the heat exchanger body 5. When the heat exchanger body 5 requires maintenance after prolonged use, the user can activate the electric push rod 19 via an external controller. The electric push rod 19 facilitates the retraction and movement of the push plate 18, which in turn causes the push plate 18 to retract and move the limit rod 2. The limit rod 2 then pushes the limit plate 3 to move, disengaging it from the groove on the surface of the mounting block 4. This allows the heat exchanger body 5 to be released from its limit position, facilitating disassembly, maintenance, and cleaning. This greatly improves the utilization efficiency of the heat exchanger body 5 and indirectly enhances its heat exchange efficiency.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
