A right plate is fixedly connected to the tank. Flow grooves are provided between the top of the left plate and the bottom of the right plate and the inner cavity of the tank. A hot outlet pipe is fixedly connected to the top of the tank away from the hot inlet pipe. A cold inlet pipe is fixedly connected to the side of the tank near the hot inlet pipe. A filter plate is slidably connected inside the top of the cold inlet pipe. The filter plate includes an outer sealing ring. Several supports are fixedly connected to the top of the sealing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention, by setting up heat exchange tubes and isolation components, allows the device to transport cold fluid through uniformly distributed heat exchange tubes, and then inject a larger quantity of hot fluid for heat exchange. The isolation components divide the inside of the tank into multiple spaces, slow down the flow rate of the hot fluid, and disrupt the flow direction of the hot fluid, so that it can fully contact the heat exchange tubes and transfer heat to the cold fluid, thereby improving the working efficiency of the device.
[0016] This utility model, by setting a sealing ring, a bracket, and a connecting ring, enables the device to ensure a seal between the filter plate and the cold inlet pipe through the sealing ring. Furthermore, the design of the bracket and mounting ring allows the filter plate to be fitted inside the cold inlet pipe, simplifying the filter plate replacement process, speeding up the replacement process, and improving the practicality of the device.

[0021] The present invention will be further described below with reference to the embodiments.
[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.
[0023] Please see Figures 1-3This utility model provides a horizontal tube-and-shell high-efficiency energy-saving heat exchanger, including a tank body 1. Both ends of the inner cavity of the tank body 1 are fixedly connected to partitions 2. A plurality of heat exchange tubes 3 are fixedly connected between the two partitions 2. A plurality of isolation components 4 are fixedly connected to the inner cavity of the tank body 1 located between the two partitions 2. A hot inflow pipe 5 is fixedly connected to one end of the top of the tank body 1. A cold inflow pipe 7 is fixedly connected to the side of the tank body 1 near the hot inflow pipe 5. A filter plate 8 is slidably connected inside the top of the cold inflow pipe 7. The filter plate 8 includes an outer sealing ring 9, and a plurality of [missing information - likely related to heat exchange tubes] are fixedly connected to the top of the sealing ring 9. The support 10 has its top end abutting against the top of the cold inlet pipe 7. Several supports 10 are fixedly connected to the same connecting ring 11 at one end outside the cold inlet pipe 7. The bottom of the tank 1 is fixedly connected to both sides of the bottom of the tank 1. An observation window is fixedly connected to one side of the tank 1. The bottom end of the tank 1 away from the cold inlet pipe 7 is fixedly connected to the cold outlet pipe 14. A valve is fixedly connected to the outside of the cold outlet pipe 14. Several fixing grooves with positions and shapes adapted to the supports 10 are opened at the top of the cold inlet pipe 7. The connecting ring 11 is fixedly connected to both sides of the connecting ring 11.
[0024] The filter plate 8 is slid into the cold inlet pipe 7 by the handle 12, so that the bracket 10 is locked into the fixing groove. The cold fluid is added to the cold inlet pipe 7, filtered by the filter plate 8, and then the cold fluid enters the tank 1.
[0025] The sealing ring 9 fits tightly between the inner cavities of the cold inlet pipe 7, ensuring a leak-free seal on the outside of the filter plate 8. The bracket 10 abuts against the top of the cold inlet pipe 7, providing stable support for the filter plate 8 and allowing it to be securely fitted inside the cold inlet pipe 7. Even under high pressure or high-speed fluid flow, the filter plate 8 remains stable and will not shake or fall off. The connecting ring 11 connects multiple brackets 10 together, forming an easy-to-grip and operate integrated structure, which greatly simplifies the steps of replacing the filter plate 8, significantly speeds up the replacement process, reduces downtime, and improves the utilization and practicality of the entire device.
[0026] Please see Figures 1-3 The isolation assembly 4 includes a left plate 401 fixedly connected to the inside of the tank 1. Several connecting blocks 402 are fixedly connected to the side of the left plate 401 away from the heat inflow pipe 5. The same right plate 403 is fixedly connected to the other side of the several connecting blocks 402. Flow grooves are left between the top of the left plate 401 and the bottom of the right plate 403 and the inner cavity of the tank 1. A heat outflow pipe 6 is fixedly connected to the top of the tank 1 away from the heat inflow pipe 5. The heat inflow pipe 5 and the heat outflow pipe 6 are both located between the two partitions 2 and on both sides of all the isolation assemblies 4. There are three isolation assemblies 4, which divide the space between the two partitions 2 into four equal spaces. A movable cavity is formed between the left plate 401 and the right plate 403. A fixing groove adapted to the heat exchange pipe 3 is opened on the inside of the isolation assembly 4.
[0027] Then it enters the annular heat exchange tubes 3 and flows to the other end. At the same time, the hot fluid is added into the tank 1 through the hot inlet pipe 5. The space between the two baffles 2 flows through the flow channel and moving cavity inside the isolation component 4. The cold fluid and the hot fluid exchange heat in the tank 1 through the heat exchange tubes 3. Then the heated cold fluid flows out of the heat exchanger through the cold outlet pipe 14, and the heated hot fluid flows out of the heat exchanger through the hot outlet pipe 6.
[0028] The heat exchange tubes 3 are evenly distributed inside the tank 1, acting as a bridge for heat transfer between the cold and hot fluids. The flow space and quantity of the hot fluid are greater than those of the cold fluid, which ensures that the hot fluid has sufficient heat supply to effectively heat the cold fluid. The isolation components 4 divide the interior of the tank 1 into multiple relatively independent but interconnected spaces. This design significantly slows down the flow rate of the hot fluid. When the hot fluid flows through these spaces divided by the isolation components 4, its flow direction is constantly disrupted, thereby increasing the contact area and contact time between the hot fluid and the heat exchange tubes 3, and thus transferring more heat to the cold fluid. This not only improves the working efficiency of the device, but also ensures the stability and reliability of the heat exchange process.
[0029] The working principle and usage process of this utility model are as follows: The filter plate 8 is slid into the cold inlet pipe 7 through the handle 12, so that the bracket 10 is locked into the fixing groove. The cold fluid is added to the cold inlet pipe 7 and filtered by the filter plate 8. Then the cold fluid enters the tank 1 and then enters the annular heat exchange tubes 3 and flows to the other end. At the same time, the hot fluid is added to the tank 1 through the hot inlet pipe 5. The space between the two partitions 2 flows through the flow groove and moving cavity inside the isolation component 4. The cold fluid and the hot fluid exchange heat in the tank 1 through the heat exchange tubes 3. Then the heated cold fluid flows out of the heat exchanger through the cold outlet pipe 14, and the heated hot fluid flows out of the heat exchanger through the hot outlet pipe 6.
