Description

Technical Field

[0001] This invention relates to the technical field of electromagnetic shielding windows, and more particularly to a metal mesh sandwich electromagnetic shielding window with full-band shielding effectiveness. Background Technology

[0002] Electromagnetic shielding windows, with multi-layered ultra-fine photolithographic metal mesh as the core shielding layer, combined with multi-layered composite conductive edge sealing and conductive sealed window frames, can cover the entire band of radio frequency, microwave, and low-frequency magnetic fields to achieve high attenuation shielding. Relying on the good conductor of the metal mesh to reflect and block high-frequency electromagnetic waves, they are mainly installed in the command cabin and radar control room of ships to reject external radar and electromagnetic pulse interference, ensure the stable operation of navigation equipment, and lock the internal communication radio frequency signals, taking into account the needs of marine light transmission observation and electromagnetic protection in all scenarios.

[0003] However, in existing technologies, the marine environment of ships experiences large temperature differences between day and night. The alternating effects of low-temperature sea areas, tropical sun exposure, and continuous radar heat radiation cause an uneven temperature field in the glass. The expansion and contraction of different areas of the metal mesh are not synchronized, leading to interlayer tension and compression, creating continuous alternating shear stress, i.e., thermal stress. Simultaneously, the metal mesh only contacts the heat exchange medium at its edges, with heat conduction lagging in the center. This asynchronous thermal deformation further amplifies interlayer stress. Under long-term cyclical action, the adhesive layer gradually separates from the bonding interface between the glass and the metal mesh. Furthermore, moisture seeping in due to seal failure weakens the PVB bonding strength, accelerating the delamination process. After delamination, air bubbles and cavitation form inside the interlayer. Light refracts and scatters through these bubbles, blurring the field of vision and exacerbating the diffraction patterns of the mesh. This makes target identification difficult during surface observation, seriously affecting navigational safety. The electromagnetic shielding performance deteriorates, and delamination causes the metal mesh to be partially suspended and warped, resulting in broken mesh wires and interrupted conductive paths. The metal mesh on the glass side separates from the conductive sealing strip along with the delamination, forming continuous electromagnetic leakage gaps. This makes it easy for radio frequency signals inside the cabin to leak out. Furthermore, the durability of the shielding window structure decreases rapidly. Delamination gaps easily trap salt spray and water vapor, and the metal mesh wires oxidize and turn black quickly upon contact with chloride ions. The conductivity resistance continues to increase, and the shielding effectiveness continues to decline. Repeated tearing by thermal stress will expand the delamination area. Under extreme conditions, the glass may crack locally, losing its explosion-proof and impact-resistant capabilities. There is a risk of glass breakage from wave impacts. The air gap formed by delamination has extremely poor thermal conductivity, making it even more difficult for heat to be conducted from the edges to the center of the glass. The temperature difference between the panels further increases, and the thermal stress continues to intensify, accelerating the overall failure of the shielding window and affecting stable operation. Summary of the Invention

[0004] The purpose of this invention is to provide a metal mesh sandwich electromagnetic shielding window with full-band shielding effectiveness, solving the problem of weakened shielding due to delamination caused by temperature differences.

[0005] The technical solution of the present invention is as follows: a metal mesh sandwich electromagnetic shielding window with full-band shielding effectiveness, comprising a window frame body, a shielding cover rotatably connected to the window frame body, a frame fixedly connected inside the window frame body, two protective glasses provided and snapped into the frame, a mesh wire snapped between the two protective glasses, a circulator and a copper frame provided inside the window frame body, two copper strips provided and fixedly connected to the copper frame, and two diverters provided and fixedly connected inside the window frame body. The two copper strips are symmetrically arranged about the central axis of the window frame body, and the two diverters are respectively located above and below the window frame body. The copper frame divides the interior of the window frame body into an inner flow channel and an outer flow channel, and the diverters are used to switch the flow path of the inner flow channel and the outer flow channel.

[0006] Furthermore, the copper frame includes two vertical sides and a horizontal side, the vertical sides are fixedly connected to the horizontal side, and multiple first copper plates and second copper plates are equidistantly arranged on one side of the vertical side located in the inner flow channel.

[0007] Furthermore, the first copper plate and the second copper plate are staggered, the height of the first copper plate is greater than the height of the second copper plate, and the bottom edge of the second copper plate coincides with the center line of the vertical edge.

[0008] Furthermore, both the first copper plate and the second copper plate are provided with round holes, and one end of the vertical side extends into a side plate, which separates the interior of the outer flow channel. Flow holes are provided on the side plate and the vertical side.

[0009] Furthermore, the outer side of the mesh is provided with heat-conducting ribs, the inner side of the heat-conducting ribs is inserted between the two protective glass plates, the first copper plate and the second copper plate are both in contact with the outer wall of the heat-conducting ribs, and the outer edge thickness of the protective glass is less than the center thickness of the protective glass.

[0010] Furthermore, the diverter includes a heat-conducting pipe fixedly connected inside the window frame body, a sleeve slidably connected outside the heat-conducting pipe, a connecting disc fixedly connected to the sleeve, a bar fixedly connected to the connecting disc, a temperature-controlled spring connected between the heat-conducting pipe and the sleeve, and a protective sleeve sleeved outside the temperature-controlled spring. The protective sleeve is fixedly connected to the heat-conducting pipe, and the temperature-controlled spring does not contact the protective sleeve.

[0011] Furthermore, the heat pipe is located inside the inner flow channel, the sleeve and the bar shaft are respectively located inside the corresponding flow holes, and multiple copper discs are equidistantly connected between the heat pipe and the heat-conducting rib.

[0012] Furthermore, the copper strip is fixedly connected between the first copper plate and the second copper plate, the copper strip passes through a circular hole, and the interior of the copper strip is hollow.

[0013] Furthermore, the diameter of the sleeve is equal to the diameter of the flow hole, a plug ring is provided at the end of the strip shaft away from the connecting disc, the diameter of the plug ring is equal to the diameter of the flow hole, the diameter of the strip shaft is smaller than the diameter of the flow hole, and the connecting disc does not contact the copper frame.

[0014] Furthermore, a cover plate is snapped onto one side of the window frame body, the cover plate sealing one side of the window frame body, and an interface is provided on the outer side of the window frame body, the interface being located at the position of the snap-on circulator.

[0015] The beneficial effects of this invention are: 1. By using ultra-fine photolithographic metal mesh as a shielding component, combined with copper frames and copper strips to form a closed-loop continuous conductive network, full-band electromagnetic shielding protection can be achieved, adapting to complex electromagnetic operation scenarios on ships. At the same time, the overall conductive path of the equipment is complete and uninterrupted, without local conductive interruptions or electromagnetic leakage gaps, and can maintain stable full-band shielding performance for a long time, meeting the needs of long-term, high-intensity, and highly confidential maritime operations on ships. Furthermore, the symmetrically arranged shunts rely on temperature-controlled springs to achieve passive adaptive adjustment, without the need for external control components. They can dynamically switch the dual-channel medium flow path, quickly conduct heat dissipation under high-temperature conditions, and limit current and keep the temperature under low-temperature conditions. This ensures that the temperature deformation rhythm of the glass and metal mesh is completely synchronized, completely avoiding the generation of interlayer alternating stress, eliminating problems such as structural cracking, misalignment, and deformation, and improving the structural durability of the equipment during long-term operation.

[0016] 2. By using alternating high and low copper plates and heat-conducting ribs distributed throughout the entire area, a three-dimensional heat-conducting structure is constructed to achieve uniform temperature distribution throughout the mesh and protective glass. The mesh, relying on its excellent electrical and magnetic conductivity, can achieve a high attenuation shielding effect against radio frequency, microwave, and low-frequency magnetic fields. On the one hand, it can effectively block external radar detection and electromagnetic pulse interference, and protect the stable operation of precision electronic equipment inside the cabin in all aspects, avoiding equipment failure and data deviation caused by electromagnetic interference. On the other hand, it can completely lock the leakage of communication radio frequency signals inside the cabin, eliminating the safety hazards caused by ship signal leakage.

[0017] 3. By employing a high-strength rigid sandwich structure for the main window frame, it effectively resists external loads such as the impact of ocean waves and high-frequency vibrations of the ship's hull. This ensures the overall shape of the equipment remains regular from a fundamental perspective, eliminating structural problems such as deformation and misalignment. Simultaneously, the double-layered symmetrical protective glass utilizes a differentiated structure with thinner edges and a thicker center. This thickened central area ensures overall impact and explosion-proof performance, resisting damage from complex external forces at sea, while the thin edges reduce thermal resistance, optimizing the overall temperature field in conjunction with the heat exchange structure. Furthermore, the equipment adopts a modular snap-fit ​​assembly structure with uniform interlayer spacing and excellent sealing performance. This maintains a dry and sealed environment inside the sandwich layer for extended periods, stabilizing the adhesive layer performance and making it resistant to sea salt spray and water vapor corrosion, suitable for all-weather, all-scenario operations on ships.

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-9This invention provides a metal mesh sandwich electromagnetic shielding window with full-band shielding effectiveness, comprising a window frame body 1, a shielding cover 2 rotatably connected to the window frame body 1, a frame 3 fixedly connected inside the window frame body 1, two protective glasses 4 snapped into the frame 3, a mesh wire 5 snapped between the two protective glasses 4, a circulator 6 and a copper frame 7 disposed inside the window frame body 1, two copper strips 8 fixedly connected to the copper frame 7, and two diverters 9 fixedly connected inside the window frame body 1. The two copper strips 8 are symmetrically arranged about the central axis of the window frame body 1, and the two diverters 9 are located above and below the window frame body 1, respectively. The copper frame 7 divides the interior of the window frame body 1 into an inner flow channel 10 and an outer flow channel 11, and the diverters 9 are used to switch the flow paths of the inner flow channel 10 and the outer flow channel 11.

[0022] A temperature sensor is connected between the window frame body 1 and the cover 2.

[0023] Specifically, the main body of the window frame 1 possesses high-strength structural rigidity, effectively resisting external loads such as the impact of sea waves and ship vibrations, preventing deformation and misalignment of the equipment. Simultaneously, the internal structure of the main body of the window frame 1 is a sandwich structure, providing a solid foundation for equipment installation. A rotatable shielding cover 2 is mounted on the outer side of the main body of the window frame 1, which can be flexibly opened and closed according to the actual working environment, effectively blocking strong external light. This, combined with the internal temperature control structure, maintains a balanced window temperature. An internal fixed frame 3 securely holds two sets of protective glass 4 and the mesh 5 laid in between, effectively ensuring uniform spacing between the double-glazed glass and the metal mesh interlayer, and consistent assembly alignment. The design ensures uniform stress distribution and a regular shape within the overall sandwich structure, maintaining a sealed and dry internal environment, stabilizing the adhesive layer's bonding performance, and guaranteeing the long-term integrity of the sandwich structure. The double-layered, symmetrically arranged protective glass 4 forms the main light-transmitting and protective element, stably holding and wrapping the central mesh 5, preserving high-definition light transmission. It possesses excellent explosion-proof, impact-resistant, and structural protection performance, effectively resisting complex external impacts at sea, enhancing the overall structural strength of the window, and eliminating the risk of glass breakage. The internal mesh 5 is the core functional component for electromagnetic shielding of the equipment. Utilizing the excellent conductivity and magnetic permeability of the ultra-fine photolithographic metal mesh, it can comprehensively cover radio frequency, microwave, and low-frequency magnetic fields, achieving a full-band high-attenuation screen. The shielding system not only blocks external radar and electromagnetic pulses from interfering with the precision equipment inside the cabin, but also prevents leakage of communication radio frequency signals, achieving two-way electromagnetic protection. The copper frame 7 can be directly installed around the mesh 5, quickly absorbing the heat accumulated during the mesh's operation, addressing the shortcomings of heat accumulation in the center and delayed heat exchange at the edges of the metal mesh. Simultaneously, the copper frame 7 divides the window frame into an inner flow channel 10 and an outer flow channel 11. Combined with symmetrically arranged copper strips 8, this enhances the overall heat conduction coverage and uniformity, enabling synchronous heat exchange between the window edges and center, ensuring the mesh 5 and glass deformation rhythm remain synchronized. The circulator 6 provides continuous power for the circulation of the flow medium, ensuring... The heat exchange system operates stably, while the symmetrically arranged splitter 9 can dynamically switch the dual-channel flow path according to the working conditions, adapting to different operating environments such as high temperature exposure, low temperature sea area, and equipment heat radiation, dynamically balancing the overall temperature of the window, ensuring the synchronous thermal deformation of each component from the structural operation level, and completely avoiding the generation of interlayer alternating stress. At the same time, the copper frame 7 and copper strip 8 form a continuous closed-loop conductive network, which is closely attached to the mesh wire 5 for conduction, maintaining a complete and uninterrupted conductive shielding path throughout the process, effectively avoiding local conductive interruption and electromagnetic leakage gaps, continuously stabilizing the shielding performance of the equipment across the entire frequency band, and meeting the safety operation requirements of ships in all scenarios and for long periods.

[0024] Reference Figures 1-8 The copper frame 7 includes two vertical sides 07 and a horizontal side 17. The vertical sides 07 and the horizontal side 17 are fixedly connected. On one side of the vertical side 07 located in the inner flow channel 10, multiple first copper plates 71 and second copper plates 72 are equidistantly arranged.

[0025] The first copper plate 71 and the second copper plate 72 are staggered. The height of the first copper plate 71 is greater than the height of the second copper plate 72. The bottom edge of the second copper plate 72 coincides with the center line of the vertical edge 07.

[0026] Both the first copper plate 71 and the second copper plate 72 have round holes 701. One end of the vertical side 07 extends into a side plate 711, which separates the interior of the outer flow channel 11. Flow holes 702 are provided on the side plate 711 and the vertical side 07.

[0027] Specifically, the copper frame 7 is formed by two symmetrically arranged vertical sides 07 and upper and lower horizontal sides 17. On the inner wall of the inner flow channel 10, the vertical sides 07 of the copper frame 7 are equidistantly arranged with primary copper plates 71 and secondary copper plates 72. Through the primary copper plates 71 and secondary copper plates 72, the copper frame 7 can completely conform to the outer contour of the mesh 5. Through this staggered structure, a comprehensive layered heat exchange enhancement effect is achieved. The primary copper plate 71 has a greater vertical height than the secondary copper plate 72, and the bottom edge of the secondary copper plate 72 is strictly aligned with the center line of the vertical side 07. This overcomes the limitation of the traditional single flat plate heat exchange structure with its limited coverage area, utilizing the staggered copper plates... The layout can correspond to different areas vertically above and below the mesh 5, achieving layered bonding and zoned heat exchange. The high-profile primary copper plate 71 covers the main heat-accumulating area at the top of the mesh 5, quickly dissipating concentrated heat. Simultaneously, the secondary copper plate 72, positioned in the middle, fills the heat exchange blind spot in the middle, solving the problems of heat accumulation and asynchronous hot and cold deformation in the middle, ensuring a highly uniform temperature distribution across the mesh 5 and suppressing the generation of thermal shear stress at its source. Furthermore, both the primary copper plate 71 and the secondary copper plate 72 have through-holes 701, constituting an active heat exchange enhancement structure. This is understandable, as traditional solid heat-conducting plates rely solely on surface contact for heat exchange. The single-sided flow of the medium is obstructed, limiting heat exchange efficiency. The circular hole 701 allows the circulating heat exchange medium inside the inner flow channel 10 to directly penetrate the copper plate body, enabling an immersive three-dimensional heat exchange between the medium, copper plate, and mesh 5. This is no longer limited to single-sided contact heat conduction, increasing the heat exchange rate and quickly removing the accumulated heat absorbed by the copper frame 7 from the surface of the mesh 5. This prevents heat from remaining trapped inside the interlayer for extended periods, maintaining the window's temperature balance and ensuring synchronized deformation of the glass and metal mesh. Furthermore, the integrated side plate 711 at the end of the vertical edge 07 can separate the internal space of the outer flow channel 11, achieving zoned flow guidance and avoiding the limitations of a single-sided flow channel. In cases of turbulent flow without partitioning of the flow channel, the side plate 711 acts as a divider, regulating the flow trajectory of the medium and allowing the circulating medium to flow smoothly along a preset path, thus improving the stability of the medium circulation. At the same time, the flow holes 702 on the vertical side 07 and the side plate 711 enable the medium to communicate, guide, and balance the pressure between the inner flow channel 10 and the outer flow channel 11, forming a closed-loop circulation system between the two channels. This allows the copper frame 7 to participate in heat exchange both vertically and horizontally, maximizing the utilization of the overall thermal conductivity of the copper frame 7, continuously and efficiently dissipating the heat accumulated in the mesh wire 5, and improving the structural durability and shielding reliability of the shielded window under complex alternating conditions at sea.

[0028] Reference Figures 1-8 The mesh 5 is equipped with heat-conducting ribs 51 on its outside. The inner side of the heat-conducting ribs 51 is inserted between the two protective glass panes 4. The first copper plate 71 and the second copper plate 72 are both attached to the outer wall of the heat-conducting ribs 51. The outer edge thickness of the protective glass 4 is less than the center thickness of the protective glass 4. This is to accommodate the installation of the heat-conducting ribs 51, enabling the window edge to exchange heat quickly and the center to maintain a uniform temperature. The thin edge structure has lower thermal resistance and can work with the copper frame 7 and the heat-conducting ribs 51 to quickly complete the edge heat exchange, further reducing the temperature difference between the center and the edge of the glass. The thickened central area can ensure the overall structural strength of the protective glass 4 and further optimize the uniformity of the overall temperature field of the window, making it suitable for the complex working conditions of alternating hot and cold at sea.

[0029] Specifically, heat-conducting ribs 51 are integrally set on the outside of the wire mesh 5. The inner side of the heat-conducting ribs 51 is stably inserted into the gap between the two layers of protective glass 4, forming an integral heat-conducting structure with the wire mesh 5. This allows the heat accumulated by the wire mesh 5 to be directly and quickly conducted to the outer heat-conducting ribs 51, actively extending the heat-conducting and heat-exchange boundary of the wire mesh 5 and constructing a three-dimensional heat-conducting path that diffuses from the center of the wire mesh 5 to the surrounding heat-conducting ribs 51. At the same time, the outer wall surface of the heat-conducting ribs 51 is completely and tightly attached to the first copper plate 71 and the second copper plate 72 of the copper frame 7. Through the heat-conducting ribs 51, large-area heat conduction is achieved, allowing the heat of the entire area of ​​the wire mesh 5 to be quickly and evenly transferred to the heat exchange structure of the copper frame 7 and carried away by the circulating medium. This completely eliminates the phenomenon of heat accumulation in the middle of the wire mesh 5 and lag in heat exchange at the edges, ensuring a high degree of uniformity in the overall hot and cold deformation of the wire mesh 5.

[0030] Reference Figures 1-9 The diverter 9 includes a heat-conducting pipe 91 fixedly connected inside the window frame body 1, a sleeve 92 slidably connected outside the heat-conducting pipe 91, a connecting disc 93 fixedly connected to the sleeve 92, a bar shaft 94 fixedly connected to the connecting disc 93, a temperature control spring 95 connected between the heat-conducting pipe 91 and the sleeve 92, and a protective sleeve 96 sleeved outside the temperature control spring 95. The protective sleeve 96 is fixedly connected to the heat-conducting pipe 91, and the temperature control spring 95 does not contact the protective sleeve 96.

[0031] The heat pipe 91 is located inside the inner flow channel 10, the sleeve 92 and the bar 94 are located inside the corresponding flow holes 702 respectively, and multiple copper disks 911 are equidistantly connected between the heat pipe 91 and the heat-conducting rib 51, so that the entire distributor 9 can extract temperature through the copper disks 911.

[0032] When the temperature control spring 95 is not deformed, the sleeve 92 will close the corresponding flow hole 702.

[0033] Specifically, the heat pipe 91 serves as the base support structure, and is integrally arranged inside the inner flow channel 10, allowing direct contact with the circulating heat exchange medium within the inner flow channel 10. Simultaneously, multiple sets of copper disks 911 are equidistantly fixedly connected between the heat pipe 91 and the heat-conducting ribs 51 on the outer side of the mesh 5. The copper disks 911 function as temperature transfer devices, capable of real-time acquisition of temperature changes between the mesh 5 and the heat-conducting ribs 51, allowing the heat pipe 91 to simultaneously sense the overall temperature status of the window interlayer. A sliding sleeve is mounted externally on the heat pipe 91. 92. The sleeve 92 can slide smoothly along the axial direction of the heat pipe 91 to realize the opening, closing and switching control of the flow cross section and flow path of the flow channel. The tail of the sleeve 92 is fixedly connected to the connecting plate 93, and the outer side of the connecting plate 93 is fixedly provided with a strip shaft 94. The sleeve 92 and the strip shaft 94 are respectively inserted into the flow holes 702 of the copper frame 7 and the side plate 711. This makes the sliding stroke of the sleeve 92 and the strip shaft 94 completely correspond to the opening and closing area of ​​the flow hole 702, which can control the mutual flow rate and flow state of the dual-channel medium. The system enables adaptive switching between rapid heat dissipation under high-temperature conditions and current-limiting insulation under low-temperature conditions. A temperature-controlled spring 95 is installed between the heat pipe 91 and the sleeve 92. As the core component of the adaptive power system, it automatically expands and retracts based on temperature deformation stress, eliminating the need for an external power source and control components. This results in a simple structure with strong anti-interference capabilities. To further enhance the operational stability of the temperature-controlled spring 95, a protective sleeve 96 is specially designed. The protective sleeve 96 is fixedly fitted to the outside of the heat pipe 91 and wraps around the temperature-controlled spring 95, providing physical isolation and protection. This effectively blocks the erosion and jamming effects of impurities, salt spray crystals, and water vapor accumulation in the flow channel on the spring structure, extending the spring's service life. At the same time, a gap-type layout is strictly adopted, ensuring that the temperature-controlled spring 95 does not contact the protective sleeve 96, completely avoiding problems such as frictional resistance, scratch wear, and temperature conduction interference. This ensures that the temperature-controlled spring 95 can freely expand and contract with temperature changes, guaranteeing temperature sensing sensitivity and adjustment accuracy.

[0034] Reference Figures 1-9 The copper strip 8 is fixedly connected between the first copper plate 71 and the second copper plate 72. The copper strip 8 passes through the round hole 701. The interior of the copper strip 8 is hollow to facilitate the flow of coolant.

[0035] The diameter of the sleeve 92 is equal to the diameter of the flow hole 702. A plug ring 941 is provided at the end of the bar shaft 94 away from the connecting plate 93. The diameter of the plug ring 941 is equal to the diameter of the flow hole 702. The diameter of the bar shaft 94 is smaller than the diameter of the flow hole 702. The connecting plate 93 does not contact the copper frame 7.

[0036] Specifically, the equal-diameter sleeve 92 can completely fit the inner wall of the flow hole 702 to achieve full-section sealing when sliding and sealing under low-temperature conditions. This completely isolates the medium flow between the inner flow channel 10 and the outer flow channel 11, reduces heat loss from the window, avoids interlayer stress caused by uneven deformation at low temperatures, and prevents medium leakage and salt spray impurities from entering the interlayer, causing corrosion and aging. Furthermore, the plug ring 941 at one end of the bar shaft 94 can be inserted into the corresponding flow hole 702 during the reciprocating sliding process, serving as an axial guide and barrier to form a joint and close the local channel. At this time, the other flow hole 702 opens to divert and accelerate the flow of coolant, achieving stable and balanced flow.

[0037] Reference Figures 1-9 A cover plate 101 is snapped onto one side of the window frame body 1, and the cover plate 101 closes one side of the window frame body 1. An interface 102 is provided on the outside of the window frame body 1, and the interface 102 is located at the position of the snap-on circulator 6.

[0038] Specifically, a cover plate 101 is snapped onto one side of the window frame body 1, which enables quick assembly and disassembly through snap-fit. The cover plate 101 can completely seal the opening on the side of the window frame body 1, effectively protecting the precision heat exchange and control components inside the window frame, such as the circulator 6, the diverter 9, and the copper frame 7, ensuring the long-term integrity and stability of the shielded window interlayer structure.

[0039] An interface 102 is provided on the outer side of the window frame body 1 at the assembly position corresponding to the circulator 6. The interface 102 is aligned and matched with the circulator 6. The use of the dedicated alignment interface 102 can improve the assembly accuracy of the circulator 6 and the convenience of disassembly and maintenance, avoid problems such as pipe misalignment, medium leakage, and insufficient circulation power, effectively ensure the continuous and efficient operation of the entire adaptive temperature control heat exchange system, and further improve the temperature balance capability and structural durability of the shielded window under complex alternating marine conditions.

[0040] The working principle of this invention is as follows: The mesh wire 5 generates heat, which is first conducted to the integrally formed heat-conducting ribs 51 on the outside. The outer wall of the heat-conducting ribs 51 is tightly attached to the first copper plate 71 and the second copper plate 72 of the copper frame 7, which are arranged in an alternating manner, to complete the rapid heat transfer. The hollow copper strip 8 passes through the round hole 701 of the copper plate and connects the copper plates on both sides, widening the heat conduction coverage. The copper plates of different heights are layered and attached to the heat-conducting ribs 51 to guide the heat accumulation in the middle and upper parts of the mesh wire 5 in different areas. The medium passes through the round hole 701 and forms a three-dimensional heat exchange with the hollow copper strip 8, improving the heat exchange efficiency. The vertical side 07 of the copper frame 7 extends to the side plate 711 to separate the outer flow channel 11. The flow holes 702 on the vertical side 07 and the side plate 711 realize the mutual communication of the dual flow channels. The heat-conducting pipe 91 collects the real-time temperature of the heat-conducting ribs 51 through the copper plate 911. Under normal temperature conditions, the temperature control spring 95 does not deform. The cap 92 blocks the flow hole 702, separating the inner flow channel 10 and the outer flow channel 11. The circulator 6 drives the process. The heat exchange medium circulates only in the inner flow channel 10. The copper plate slowly and evenly distributes the residual heat to maintain the temperature balance of the interlayer. Under high-temperature conditions, the heat pipe 91 heats up, causing the temperature control spring 95 to extend due to heat. This pushes the connecting plate 93 to drive the sleeve 92 and the bar shaft 94 to slide synchronously. The corresponding flow hole 702 opens, and the plug ring 941 at one end of the bar shaft 94 enters the corresponding flow hole 702 to seal it. The dual flow channels in the vertical side 07 area and the horizontal side 17 area are connected through the flow hole 702. The circulating medium flows through the two flow channels at the same time. The side plate 711 regulates the flow direction of the medium. The window edge and the center dissipate heat synchronously, eliminating local high temperature and lowering the overall temperature. The temperature control spring 95 shrinks and resets, pulling the sleeve 92 back to seal the flow hole 702. The dual flow channels are isolated again. Different media circulate at low speed in the corresponding flow channels to reduce heat loss to the outside. Combined with the copper heat-conducting component, the heat dissipation is balanced, reducing the temperature difference between the center and edge of the glass and avoiding interlayer stress caused by inconsistent thermal deformation.
