Description

Technical Field

[0001] This invention relates to the field of heat exchange structure technology, and in particular to a shape-controlled heat exchange component. Background Technology

[0002] In related technologies, heat exchange structures often employ fixed geometric configurations, such as spiral tubes. Once manufactured, the internal flow channel shape and heat exchange area of ​​such structures are fixed and cannot be adjusted according to changes in operating conditions.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] The following is based on Figures 1 to 4 This invention introduces a shape-controlled heat exchange component according to an embodiment of the present invention.

[0022] like Figure 1 As shown, the shape-controlled heat exchange component of this embodiment includes a main heat exchange structure 1, a main deformation structure 2, two pressure plates 3, and a drive system.

[0023] The main heat exchange structure 1 has a main heat exchange channel inside, which includes multiple three-period minimal curved surface lattice frameworks.

[0024] The interior of the main deformation structure 2 has auxiliary heat transfer channels, including multiple chiral cell frameworks capable of elastic deformation.

[0025] The main heat exchange structure 1 and the main deformation structure 2 are located between the two pressure plates 3.

[0026] The drive system is electrically connected to the pressure plate 3 to drive the two pressure plates 3 to move closer or further apart, thereby adjusting the size of the auxiliary heat exchange channel and thus adjusting the heat exchange efficiency of the heat exchange component.

[0027] The main heat exchange structure 1 contains main heat exchange channels and comprises multiple periodic three-period minimal surface cell frameworks. These three-period minimal surfaces (such as Gyroid, Diamond, Primitive, or IWP structures) have a highly interconnected three-dimensional porous morphology, providing a large specific surface area within a limited space, which is beneficial for sufficient heat exchange between the fluid and the solid framework. The main heat exchange structure 1 maintains its essentially unchanged geometry during operation and primarily undertakes the main heat exchange tasks.

[0028] The main deformation structure 2 contains auxiliary heat transfer channels and comprises multiple chiral unit cell frameworks. These chiral unit cells possess helical or torsional geometry, enabling recoverable elastic deformation under external force. When the main deformation structure 2 is compressed or released, the relative positions and angles of its unit cell frameworks change, altering the cross-sectional dimensions and tortuosity of the auxiliary heat transfer channels, thereby affecting fluid flow resistance and local heat transfer intensity. The primary function of the main deformation structure 2 is to regulate heat transfer performance through deformation without compromising its overall integrity.

[0029] During operation, the fluid passes through the main heat exchange channel and the auxiliary heat exchange channel to complete heat exchange. When the operating conditions change and the heat exchange efficiency needs to be adjusted, the drive system starts, causing the two pressure plates 3 to move: if the two pressure plates 3 move closer to each other, they apply compression to the main deformation structure 2, causing elastic deformation of its chiral structure cell skeleton. The geometry of the auxiliary heat exchange channel changes accordingly, the flow channel cross-section decreases, the flow resistance increases, the fluid disturbance intensifies, and the heat exchange efficiency decreases. If the two pressure plates 3 move further apart, the main deformation structure 2 rebounds under the action of elastic restoring force, the auxiliary heat exchange channel returns to its original state or expands, the flow resistance decreases, and the heat exchange efficiency increases. By controlling the relative displacement of the pressure plates 3, the shape of the auxiliary heat exchange channel can be adjusted, thereby adjusting the overall heat exchange efficiency.

[0030] In related technologies, heat exchange structures often employ fixed geometric configurations, such as spiral tubes. Once manufactured, the internal flow channel shape and heat exchange area of ​​such structures are fixed and cannot be adjusted according to changes in operating conditions. When heat load, fluid temperature, or flow rate changes, the heat exchange efficiency cannot adapt accordingly, leading to over- or under-heat exchange capacity under certain operating conditions. Therefore, existing heat exchange structures lack the ability to dynamically adjust heat exchange efficiency.

[0031] The shape-controlled heat exchange component of this invention integrates a main heat exchange structure 1 with an elastically deformable main deformation structure 2. A drive system adjusts the distance between two pressure plates 3, subjecting the main deformation structure 2 to a controllable mechanical load. When the drive system moves the pressure plates 3, the main deformation structure 2 undergoes elastic deformation, thereby changing the shape and size of the auxiliary heat exchange channel. This change allows for adjustment of the fluid flow state within the channel according to actual operating conditions, thus regulating the overall heat exchange efficiency. Compared to existing structures with fixed heat exchange efficiency, the shape-controlled heat exchange component of this invention possesses dynamic adjustment capabilities, providing heat exchange performance adapted to different operating conditions, enhancing the applicability and flexibility of the heat exchange structure.

[0032] In addition, the main heat exchange structure 1 adopts a three-period minimal curved surface frame with high specific surface area, and its structure remains stable during operation, ensuring the continuous effectiveness of the basic heat exchange capacity.

[0033] In some embodiments, the three-period minimal surface unit cell framework includes any one of the following: Gyroid structure, IWP structure, Primitive structure, or Diamond structure.

[0034] In this embodiment, the three-period minimal curved surface lattice framework used in the main heat exchange structure 1 is selected from Gyroid, IWP, Primitive, or Diamond structures. These structures are all three-dimensional periodic continuous curved surfaces, forming a highly interconnected and non-enclosed cavity flow channel network in space, which is beneficial for fluid flow and enhances the solid-liquid contact area. Different types of curved surfaces have different effects on flow resistance and heat transfer performance, and the selection can be made according to specific heat transfer requirements.

[0035] The shape-controlled heat exchange component of this invention, by limiting the main heat exchange structure 1 to adopt one of the three-period minimal curved surfaces of the above-mentioned specific type, can provide a stable high specific surface area heat exchange foundation while maintaining a compact structure, which facilitates the achievement of consistent forming quality and thermal performance in the additive manufacturing process.

[0036] In some embodiments, the chiral structure cell framework is a first-order, second-order, or third-order chiral structure cell framework.

[0037] In this embodiment, the chiral structure cell framework in the main deformation structure 2 adopts a first-order, second-order, or third-order form. First-order chiral structures are typically single-layer helical units, while second- and third-order structures form more complex deformation mechanisms through nesting or hierarchical combinations, with their elastic deformation capacity varying with increasing order. Selecting different orders allows for adjustment of the structure's stiffness and deformation response characteristics.

[0038] The shape-controlled heat exchange component of this invention limits the chiral structure to any one of the first to third order, so that the main deformation structure 2 has predictable elastic deformation behavior when under pressure. This satisfies the geometric adjustment requirements of the auxiliary heat exchange channel and avoids local stress concentration or rebound failure due to excessive structural complexity, thereby improving the reliability of deformation control.

[0039] In some embodiments, the unit cell size of the main heat exchange structure 1 is larger than the unit cell size of the main deformation structure 2.

[0040] In this embodiment, the unit cell size of the three-period minimal curved surface unit cells in the main heat exchange structure 1 is generally larger than the unit cell size of the chiral unit cells in the main deformation structure 2. The larger unit cell size gives the main heat exchange structure 1 higher structural stiffness and load-bearing capacity, while the smaller unit cell size makes the main deformation structure 2 more prone to elastic deformation.

[0041] The shape-controlled heat exchange component of this invention sets the unit cell size of the main heat exchange structure 1 to be larger than that of the main deformation structure 2, so that the two can form a division of labor during the pressure process: the main heat exchange structure 1 maintains shape stability to ensure heat exchange function, and the main deformation structure 2 deforms first to achieve channel adjustment, thereby avoiding irreversible damage to the main heat exchange structure 1 due to excessive force.

[0042] In some embodiments, the main heat exchange structure 1 and the main deformation structure 2 are formed using an additive manufacturing process.

[0043] In this embodiment, the main heat exchange structure 1 and the main deformation structure 2 are integrally formed using the same additive manufacturing process (such as selective laser melting), without the need for subsequent welding or mechanical connection. During the manufacturing process, the two structures are stacked layer by layer in the same building space to form a continuous and transitional whole.

[0044] The shape-controlled heat exchange component of this invention uses additive manufacturing process to integrate the main heat exchange structure 1 and the main deformation structure 2, eliminating interface defects or weak bonding areas that may occur in traditional splicing methods. It is less prone to delamination or cracking during repeated deformation, thus improving the integrity of the structure and its long-term operational stability.

[0045] In some embodiments, the drive system includes a hydraulic assembly, which includes two hydraulic cylinders connected to two pressure plates 3 in a one-to-one correspondence.

[0046] In this embodiment, the drive system uses a hydraulic assembly as the actuator, including two independent hydraulic cylinders, each connected to a pressure plate 3, capable of synchronously or independently controlling the displacement of the upper and lower pressure plates 3. The hydraulic cylinders push the pressure plates 3 along the movement via piston rods, thereby compressing or releasing the main deformation structure 2.

[0047] The shape-adjustable heat exchange component of this invention is configured with two hydraulic cylinders connected to two pressure plates 3 in a one-to-one correspondence, which facilitates the control of the two pressure plates 3 to move closer or further apart from each other.

[0048] In some embodiments, the shape-adjustable heat exchange component includes a control system 4, which is electrically connected to the hydraulic component. The control system 4 controls the operation of the hydraulic component based on operating condition data to adjust the displacement of the pressure plate 3.

[0049] In this embodiment, the control system 4 establishes an electrical connection with the hydraulic components, and is able to receive external input or internally collected working condition data, and generate control signals accordingly to adjust the output pressure or stroke of the hydraulic components, thereby precisely controlling the relative position of the pressure plate 3.

[0050] The shape-controlled heat exchange component of this invention adjusts the displacement of the pressure plate 3 by introducing a control system 4, so that the deformation state of the auxiliary heat exchange channel can be dynamically adjusted according to the actual operating conditions, no longer relying on manual intervention or fixed settings, thus enhancing the adaptability of the heat exchange structure to changing operating conditions.

[0051] In some embodiments, the control system 4 includes a sensor module for acquiring operating condition data, which includes fluid temperature or flow rate signals.

[0052] In this embodiment, the sensor module is arranged at the fluid inlet, outlet, or key flow channel to acquire the fluid temperature or flow rate signal in real time and transmit these signals to the control unit as the basis for adjustment.

[0053] The shape-controlled heat exchange component of this invention collects parameters that directly reflect the heat load state, such as fluid temperature or flow rate, through a sensor module, enabling the control system 4 to respond based on real operating information.

[0054] In some embodiments, the control system 4 includes an execution control module, which controls the operation of hydraulic components based on operating condition data.

[0055] In this embodiment, the control module receives operating condition data from the sensor module or other data sources, and after logical judgment or algorithm processing, outputs command signals to the hydraulic components to drive them to adjust the position of the pressure plate 3.

[0056] The shape-controlled heat exchange component of this invention converts operating condition data into specific hydraulic action commands through an execution control module, thus realizing a complete control link from sensing to execution.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
