Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat exchangers, and particularly relates to a self-adaptive heat exchanger based on non-uniform heat exchange plates. BACKGROUND

[0002] As a kind of efficient and compact heat exchange equipment, plate heat exchangers have been widely used in many industrial fields such as chemical industry, power, metallurgy, food processing and heating, ventilation and air conditioning, etc. due to their reasonable structure, high heat transfer efficiency, convenient installation and maintenance, etc. The equipment is usually assembled by a series of metal plates with specific corrugated structure, and a plurality of thin flow channels are formed by sealing adjacent plates with gaskets. When the cold and hot fluids flow in the adjacent channels respectively, the heat is transferred efficiently between the two fluids by the good heat conduction performance of the plates, so as to realize the rapid exchange of energy.

[0003] Although the plate heat exchanger shows excellent performance in practical application, there are still some problems to be solved. Among them, in the prior art, the corrugated structure parameters of the heat exchange plate are usually uniformly distributed in a fixed form. In actual industrial production, the plate heat exchanger often needs to operate under different working conditions, such as the flow, temperature and pressure of the fluid may change with the requirements of the production process. When the working condition changes, this corrugated structure is not capable of coping with complex or changing working conditions, which is specifically reflected in the following two aspects: 1. Difficult to adapt to dynamic temperature difference distribution working condition: in the actual heat exchange process, the temperature difference between the hot fluid and the cold fluid decreases along the flow direction, and the fixed corrugated parameters fail to realize the reasonable matching of thermal resistance and heat transfer driving force, which easily causes local heat conduction efficiency of the heat exchange region to be insufficient, and the overall heat exchange performance to be reduced; 2. Poor applicability to high viscosity medium: although the dense corrugated region helps to enhance fluid disturbance and improve heat exchange intensity, when processing high viscosity fluid, it will significantly increase flow resistance and pressure drop, increase energy consumption, and even cause channel blockage, serious fouling and other operation risks, affecting system stability and energy efficiency level.

[0004] Therefore, we propose a self-adaptive heat exchanger based on non-uniform heat exchange plates to solve the above technical problems. SUMMARY

The heat exchange assembly of the present application is composed of a plurality of heat exchange hinges and is arranged from dense to sparse along the flow direction, forming a non-uniform heat exchange structure, which optimizes the flow characteristics of the fluid. In the front section of heat exchange, there is a large temperature difference between the cold and hot fluids, the heat exchange driving force is strong, the heat exchange hinges are densely arranged, and a strong disturbance effect can be formed to enhance the boundary layer destruction and fluid mixing, thereby improving the local heat exchange intensity.

The present application realizes the self-adaptive adjustment and dynamic reset ability of the structure through the synergistic action of the heat exchange hinge and the return spring, and can stably operate under variable working conditions, especially suitable for processing complex industrial fluid scenes with frequent changes in flow, temperature difference, viscosity and other parameters.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figures 1-4 This invention provides an adaptive heat exchanger based on a non-uniform heat exchange plate, including a front clamping plate 1 and a rear clamping plate 2 fastened to the rear side of the front clamping plate 1 by a clamping assembly. Each of the four corners of the front clamping plate 1 has a channel opening 3 for connecting to a pipe. A plurality of heat exchange plates 4 are arranged in a staggered manner between the front clamping plate 1 and the rear clamping plate 2. Each heat exchange plate 4 includes a first heat exchange surface and a second heat exchange surface arranged opposite each other. A fluid channel is formed between any two adjacent heat exchange plates 4, and a sealing assembly for sealing the fluid channel is provided. The sealing assembly includes an outer sealing ring 5 and an inner sealing strip 6. The outer sealing ring 5 is located at the edge of the first heat exchange surface, which includes a flow heat exchange zone 7. The system includes two corner hole isolation zones 8 and two corner hole flow zones 9. Each corner hole in the corner hole isolation zone 8 and the corner hole flow zone 9 corresponds to the position of the four corner openings 3. The internal sealing strip 6 is only provided in the two corner hole isolation zones 8, isolating the two corner hole isolation zones 8 from the flow heat exchange zone 7. The two corner hole flow zones 9 are connected to the flow heat exchange zone 7. The internal sealing strips 6 of the front heat exchange plate 4 and the rear heat exchange plate 4 of the two adjacent heat exchange plates 4 are arranged in an alternating pattern. The flow heat exchange zone 7 is provided with a heat exchange assembly. The heat exchange assembly includes multiple heat exchange hinges 10 arranged from dense to sparse along the flow direction. The heat exchange hinge 10 is provided with a reset component, which can deflect along the flow direction when under pressure and reset after the pressure is released.

[0021] In the heat exchanger, the front and rear pressing plates 1 and 2 are the basic frames, a plurality of heat exchange plates 4 are arranged in parallel and stacked between the front and rear pressing plates 1 and 2, and are tightly fixed and installed through the clamping assembly to form a stable overall structure. Four channel openings 3 on the surface of the front pressing plate 1 are respectively connected with external pipelines to realize the inlet and outlet of fluid. In the parallel and stacked heat exchange plates 4, the inner sealing strips 6 of the front heat exchange plate 4 and the rear heat exchange plate 4 in the adjacent two heat exchange plates 4 are arranged in an interlaced and spaced manner, that is, in the front heat exchange plate 4, the corner holes at the two corner hole isolation zones 8 are isolated from the flow and heat exchange zone 7, and the corner holes at the two corner hole flow-through zones 9 are communicated with the flow and heat exchange zone 7, thereby forming a fluid channel of the first fluid. Conversely, the rear heat exchange plate 4 forms a fluid channel of the second fluid according to the same principle. In actual use, the four channel openings 3 are respectively used as the low-temperature fluid inlet, the low-temperature fluid outlet, the high-temperature fluid outlet and the high-temperature fluid inlet according to the positions of the upper left, the lower left, the upper right and the lower right. Specifically, the corner holes at the two corner hole flow-through zones 9 are respectively located at the upper left and the lower left, and are respectively communicated with the low-temperature fluid inlet and the low-temperature fluid outlet, and the corner holes at the two corner hole isolation zones 8 are respectively located at the upper right and the lower right, and are respectively communicated with the high-temperature fluid outlet and the high-temperature fluid inlet. After the low-temperature fluid and the high-temperature fluid enter the inside of the heat exchanger, in the front heat exchange plate 4, the corner holes at the upper left and the lower left are enclosed in the inner sealing strip 6, and the low-temperature fluid cannot flow into the flow and heat exchange zone 7 due to isolation, and the corner holes at the upper right and the lower right are communicated with the flow and heat exchange zone 7, so that the high-temperature fluid can flow through the flow and heat exchange zone 7 from the corner hole at the lower right, exchange heat with the heat exchange hinge 10 in the flow and heat exchange zone 7, and finally flow into the corner hole at the upper right. Conversely, in the rear heat exchange plate 4, due to the position of the inner sealing strip 6, the corner holes at the upper right and the lower right are enclosed in the inner sealing strip 6, and the high-temperature fluid cannot flow into the flow and heat exchange zone 7 due to isolation, and the corner holes at the upper left and the lower left are communicated with the flow and heat exchange zone 7, so that the low-temperature fluid can flow through the flow and heat exchange zone 7 from the corner hole at the upper left, exchange heat with the heat exchange hinge 10 in the flow and heat exchange zone 7, and finally flow into the corner hole at the lower left. In this process, by forming the spaced high-temperature fluid channel and the low-temperature fluid channel, the high-temperature fluid and the low-temperature fluid are not mixed, the heat exchange plate 4 is contacted with the high-temperature fluid and the low-temperature fluid on both sides, the high-temperature fluid releases heat and cools down, and the low-temperature fluid absorbs heat and heats up, so that heat transfer is realized, the heat exchange process is completed, and the heat exchange structure is non-uniformly distributed. Compared with the traditional heat exchanger, the heat exchange assembly of the heat exchanger is composed of a plurality of heat exchange hinges 10, and is arranged from dense to sparse along the flow direction, thereby realizing the optimization of the fluid flow characteristics.Specifically, in the front section of heat exchange, due to the large temperature difference between the cold and hot fluids, the heat exchange driving force is strong, the heat exchange hinges 10 are arranged densely, a strong disturbance effect can be formed, the boundary layer destruction and fluid mixing are enhanced, and the local heat exchange intensity is improved; as the fluid gradually flows in the flow and heat exchange area 7, the temperature difference decreases, the heat exchange driving force gradually weakens, and at this time, the heat exchange hinges 10 are sparsely arranged, effectively reducing the flow resistance, controlling the energy consumption, avoiding the pressure drop rising caused by excessive flow disturbance, and realizing the reasonable matching between heat transfer and resistance. When processing high-viscosity medium, the heat exchanger also shows good adaptability. The high-viscosity medium is concentrated in the densely arranged area of the heat exchange hinges 10, and the fluid pressure is raised. When the high-viscosity fluid impacts the hinge structure, the heat exchange hinge 10 deflects under the action of the fluid in the form of "letting flow", effectively reducing the flow resistance and pressure drop, improving the flow efficiency, thereby reducing the risk of channel blockage, scaling aggravation and other operation risks, reducing energy consumption, and ensuring the stability and reliability of the system operation, and improving the comprehensive performance of the heat exchanger in the multi-working condition environment. In addition, the reset component arranged inside the heat exchange hinge 10 can restore the heat exchange hinge 10 to the original position after the fluid pressure decreases, i.e. the pressure is released, thereby realizing the self-adaptive adjustment and dynamic reset capability of the structure, and stably operating in the variable working condition, and being particularly suitable for processing complex industrial fluid scenes with frequent changes of flow, temperature difference, viscosity and other parameters.

[0022] In a specific embodiment, referring to Figure 2 and Figure 3 , the heat exchange hinge 10 comprises a first hinge seat 101, a second hinge seat 102 and a connecting shaft 103, the first hinge seat 101 is installed in the flow and heat exchange area 7, the first hinge seat 101 and the second hinge seat 102 are rotatably connected, the connecting shaft 103 penetrates the first hinge seat 101 and the second hinge seat 102, the reset component is a reset spring 11, the reset spring 11 is sleeved on the connecting shaft 103, and the included angle of the two ends of the reset spring 11 is 90 degrees and is connected with the first hinge seat 101 and the second hinge seat 102 respectively.

[0023] The heat exchange hinge 10 is composed of the first hinge seat 101, the second hinge seat 102 and the connecting shaft 103. When impacted by the fluid, the second hinge seat 102 deflects in the form of "letting flow", effectively reducing the flow resistance and pressure drop, and improving the flow efficiency. The reset component adopts the reset spring 11 sleeved on the connecting shaft 103, the included angle of the two ends thereof is 90 degrees, and the two ends are connected to the first hinge seat 101 and the second hinge seat 102 respectively, i.e. the included angle of the first hinge seat 101 and the second hinge seat 102 is 90 degrees in the initial state. When the fluid pressure is released, the reset spring 11 automatically releases the potential energy, restores the deflected second hinge seat 102 to the initial position, realizes the automatic recovery of the heat exchange hinge 10, and ensures the long-term stable operation of the structure.

[0024] In a specific embodiment, referring to Figure 3 , the first and second hinge seats 101 and 102 are respectively provided with a first sleeve 12 and a second sleeve 13, and the two ends of the reset spring 11 are respectively installed in the first sleeve 12 and the second sleeve.

[0025] Through the first sleeve 12 and the second sleeve 13, the reset spring 11 is stably connected with the first and second hinge seats 101 and 102, so that the reset spring 11 can maintain good guidance and constraint during operation, thereby ensuring that it can accurately return to the initial position after the heat exchange hinge 10 is deflected.

[0026] In a specific embodiment, referring to Figure 2 and Figure 4 , the flow-through heat exchange area 7 is provided with a positioning strip 14 on both sides, and the gap between the positioning strip 14 and the edge of the first heat exchange surface is matched with the size of the external sealing ring 5.

[0027] Through the gap between the positioning strip 14 and the edge of the first heat exchange surface, the external sealing ring 5 is clamped, preventing the external sealing ring 5 from shaking or shifting during heat exchange, effectively improving the sealing performance and reducing the risk of leakage.

[0028] In a specific embodiment, referring to Figure 2 and Figure 4 , the internal sealing strip 6 includes an angle hole sealing strip 601 and a partition sealing strip 602, the angle hole sealing strip 601 is located outside the angle hole of the angle hole isolation area 8, and the partition sealing strip 602 is arranged between the angle hole isolation area 8 and the flow-through heat exchange area 7.

[0029] The internal sealing strip 6 effectively reduces the risk of mixing of high-temperature fluid and low-temperature fluid through the double sealing of the angle hole sealing strip 601 and the partition sealing strip 602, ensures that the fluid flows along the designed path, and thus guarantees the overall heat exchange efficiency and the safety of system operation.

[0030] In a specific embodiment, referring to Figure 1 , the clamping assembly includes a plurality of threaded rods 15, the threaded rods 15 pass through the front and rear pressing plates 1 and 2, and the threaded nuts 16 are threadedly installed at both ends of the threaded rods 15.

[0031] The clamping assembly realizes the fastening connection of the front and rear pressing plates 1 and 2 through the cooperation of the threaded rods 15 and the threaded nuts 16, while ensuring that the heat exchange plates 4 can be in close contact, having good sealing performance. This installation method not only has high reliability, but also has simple structure and low maintenance cost, which is conducive to use.

[0032] In a specific embodiment, referring to Figure 1The upper and lower sides of the back of the front pressing plate 1 are respectively connected with an upper guide rod 17 and a lower guide rod 18 through screws, and the rear pressing plate 2 and the heat exchange plate 4 are both slidingly sleeved outside the upper and lower guide rods.

[0033] The upper and lower guide rods 17 and 18 can guide the installation of the heat exchange plate 4 and the rear pressing plate 2, ensure their accurate positions during the installation process, improve the parallelism and sealing of the heat exchange plate 4 stack, and ensure the stable operation of the heat exchanger under complex working conditions. In addition, the heat exchange plate 4 and the rear pressing plate 2 are slidingly sleeved outside the upper and lower guide rods, allowing the heat exchange plate 4 to be quickly disassembled and installed, thereby adjusting the capacity and heat exchange performance of the heat exchanger, and effectively improving the maintenance efficiency and system availability.

[0034] In a specific embodiment, referring to Figure 1 Further comprising a fixed column 19 and an elastic pressing part 20, the tail end of the upper guide rod 17 and the tail end of the lower guide rod 18 are connected with the upper and lower ends of the fixed column 19 through screws, and the two ends of the elastic pressing part 20 are connected with the fixed column 19 and the rear pressing plate 2 respectively and are in a compressed state.

[0035] The upper and lower ends of the fixed column 19 are connected with the tail end of the upper guide rod 17 and the tail end of the lower guide rod 18 respectively, and are connected with the rear pressing plate 2 through the elastic pressing part 20. The elastic pressing part 20 can be a spring, but is not limited thereto, and can provide a pressing force to the rear pressing plate 2, so that the front pressing plate 1 and the rear pressing plate 2 can effectively clamp the heat exchange plate 4 inside, further improving the sealing between the heat exchange plates 4, thereby reducing the risk of internal fluid leakage.

[0036] The above is only an embodiment of the present application, and does not limit the patent scope of the present application.
