[0025] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1As shown, one aspect of this disclosure provides a heat exchange plate 100, including a heat exchange plate body 110, the heat exchange plate body 110 being provided with a plurality of flow channels 120 along a first direction. The flow channels 120 are used to circulate cold fluid or hot fluid.

[0027] The channel wall 121 of the flow channel 120 includes multiple bending units 130 connected end to end.

[0028] The bending unit 130 is formed at least partially by deformable material so that the flow channel 120 can automatically adjust the bending angle of the flow channel 120 according to the temperature of the fluid.

[0029] Specifically, the deformable material automatically adjusts the bending angle of the flow channel 120 through phase change or shape memory effect when the temperature changes. When the fluid temperature is low, the deformable material contracts, the bending angle of the flow channel 120 decreases, and the fluid flows more smoothly, thereby reducing pressure drop. When the fluid temperature is high, the deformable material expands, the bending angle of the flow channel 120 increases, the fluid flow path becomes more complex, and the contact area with the channel wall 121 increases, thereby improving heat exchange efficiency.

[0030] The heat exchange plate of this embodiment can automatically adjust the flow channel bending angle according to the fluid temperature without affecting the structural strength of the heat exchange plate. The heat exchange plate can maintain high heat exchange performance under different temperature and flow rate conditions, while reducing the pressure drop of the system and adapting to changing operating conditions. The heat exchange plate has a compact structure, is easy to maintain, and is suitable for a variety of industrial application scenarios.

[0031] For example, such as Figure 2 As shown, the bending unit 130 includes a fixing part 131 and a first bending part 132 and a second bending part 133 respectively connected to both ends of the fixing part 131.

[0032] The fixing part 131 is made of a non-deformable material and does not deform when the fluid temperature changes.

[0033] Both the first bending portion 132 and the second bending portion 133 are made of deformable material. When the fluid temperature changes, the first bending portion 132 and the second bending portion 133 can change their angle according to the change in fluid temperature.

[0034] like Figure 2 As shown, in this embodiment, the bending unit 130 is S-shaped, and the channel wall 121 of the flow channel 120 is composed of multiple S-shaped bending units 130 connected end to end.

[0035] Preferably, in this embodiment, the first bending portion 132 and the second bending portion 133 can be formed using a shape memory alloy material.

[0036] Specifically, when the fluid temperature is low, the shape memory alloy material shrinks, and the bending angle of the first bending portion 132 and the second bending portion 133 decreases; when the fluid temperature is high, the shape memory alloy material expands, and the bending angle of the first bending portion 132 and the second bending portion 133 increases, so as to reduce pressure drop and improve heat exchange efficiency.

[0037] It should be noted that in this embodiment, the deformable material is not limited to shape memory alloys; other deformable materials can also be used, as long as the selected material can deform according to temperature. The material can be selected according to actual needs.

[0038] For example, the fixing part 131 is fixedly connected to the heat exchange plate body 110, and the first bending part 132 and the second bending part 133 are in contact with the heat exchange plate body 110. In this way, when the fluid temperature changes, the fixing part 131 remains fixed, while the first bending part 132 and the second bending part 133 undergo corresponding angle changes while in contact with the heat exchange plate body 110.

[0039] In this embodiment, by setting the connection relationship between the fixed part, the first bending part, and the second bending part and the heat exchange plate body, the normal flow of fluid in the guide channel can be ensured, and the bending angle of the guide channel can be automatically adjusted according to the temperature of the fluid.

[0040] For example, such as Figure 2 and Figure 3 As shown, in this embodiment, the two ends of the fixing part 131 are detachably connected to the first bending part 132 and the second bending part 133, respectively. Specifically, the two ends of the fixing part 131 can be detachably connected to the first bending part 132 and the second bending part 133 through fasteners with self-locking function, buckles, or other connection methods.

[0041] In this embodiment, the two ends of the fixing part are detachably connected to the first bending part and the second bending part, respectively. This enables the system to maintain stability and sealing under high pressure fluid or temperature change conditions, resist stress caused by fluid pressure or temperature changes, simplify the assembly and maintenance process, and improve the system's flexibility, allowing the heat exchange plates to be configured and adjusted according to actual needs.

[0042] For example, such as Figure 2 and Figure 3As shown, a dynamic sealing structure 140 is provided between the fixing part 131 and the first bending part 132 and the second bending part 133. The dynamic sealing structure 140 includes a flexible sealing material, such as fluororubber or silicone. The flexible sealing material fits tightly with a shape memory alloy or other deformable material. When the bending angle changes, the flexible sealing material can adapt to the deformation, thereby maintaining the seal and preventing fluid leakage caused by angle adjustment.

[0043] For example, the inner surface of the bending unit 130 is smoothly configured to guide the smooth flow of fluid, reduce turbulence and resistance, and further improve heat exchange efficiency and reduce energy consumption.

[0044] For example, in this embodiment, the heat exchange plate body 110 is made of a thermally conductive metal plate. The flow channels 120 can be used to circulate hot or cold fluids. In this embodiment, the hot and cold flow channels are spaced apart on the thermally conductive metal plate. The thermally conductive metal plate is made of a material with high thermal conductivity, such as copper or aluminum alloy. The heat exchange plate body 110 has a predetermined thickness, ensuring sufficient heat conduction capacity while maintaining structural stability under high temperature and high pressure conditions.

[0045] like Figure 5 As shown, under the same fluid flow conditions, pressure distribution experiments were conducted on two types of flow channels: the fixed flow channel in the prior art and the flow guide channel 120 of the heat exchange plate body 110 of this disclosure. The upper part is a schematic diagram of the pressure distribution using the fixed flow channel in the prior art; the lower part is a schematic diagram of the pressure distribution using the flow guide channel 120 of this disclosure embodiment.

[0046] Depend on Figure 5 As shown in the pressure distribution diagram, the flow channel 120 of this embodiment adopts an adjustable bending angle design, which aims to dynamically optimize the flow channel shape according to different temperatures, flow rates, or operating conditions, thereby maintaining efficient operation under various operating conditions. The pressure distribution comparison results show that, compared to a fixed traditional heat exchanger plate body, the improved heat exchanger plate body 110 significantly reduces local pressure drop, provides a more uniform pressure distribution, reduces energy loss of the fluid at bends, and improves flow efficiency.

[0047] In this embodiment, by utilizing the adaptive properties of deformable materials, the flow channel 120 automatically adjusts to a novel flow channel to reduce pressure drop under high temperature and high flow rate conditions, while reverting to a more compact traditional flow channel under low temperature or low flow rate conditions to enhance heat exchange efficiency. Thus, unlike the single performance of a fixed flow channel, the adjustable bending angle design of the flow channel 120 in this embodiment can achieve a balance between pressure drop and heat exchange efficiency under various operating conditions, significantly improving the system's adaptability and overall energy efficiency.

[0048] like Figure 4As shown, another aspect of this disclosure provides a heat exchange core 200, including a plurality of heat exchange plates 100 as described above, wherein the plurality of heat exchange plates 100 are stacked sequentially. The specific structure of the heat exchange plates 100 has been described in detail above and will not be repeated here.

[0049] It should be noted that this embodiment does not impose a specific limit on the number of heat exchange plates stacked in the heat exchange core, and can select them according to actual needs.

[0050] In the heat exchange chip of this embodiment, each flow channel can automatically adjust the bending angle of the flow channel according to the temperature of the fluid, ensuring that the high-temperature heat exchange medium and the low-temperature heat exchange medium can exchange heat to the maximum extent when flowing between adjacent plates, making full use of the heat transfer capacity between the plates, and achieving a high-efficiency and energy-saving heat exchange effect.

[0051] Another aspect of this disclosure provides a heat exchanger, including the heat exchange core described above and a shell covering the outside of the heat exchange core. The specific structure of the heat exchange core has been described in detail above and will not be repeated here.

[0052] It should be noted that the heat exchanger shell is made of corrosion-resistant materials, such as stainless steel, aluminum alloy, or composite materials with anti-corrosion coating. These materials have excellent corrosion resistance, high temperature resistance, and high pressure resistance, and can maintain structural integrity and performance stability under high temperature and high pressure conditions, ensuring the long service life and reliability of the heat exchanger.

[0053] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the embodiments of this disclosure, and the embodiments of this disclosure are not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of this disclosure, and these modifications and improvements are also considered to be within the protection scope of the embodiments of this disclosure.
