Description

Technical Field

[0001] This invention relates to the field of automotive glass technology, and in particular to a water-cooled glass assembly and system. Background Technology

[0002] Currently, heat dissipation on the inner surface of automotive glass mainly relies on air conditioning. However, air conditioning is not only inefficient but also energy-intensive. Meanwhile, existing heat insulation methods primarily include: 1. Heat absorption: increasing heat absorption by darkening the glass color, utilizing glass's high heat absorption and poor conductor of heat. 2. Heat reflection: primarily utilizing the high reflectivity of metallic silver for infrared radiation from the sun to reduce heat entering the vehicle. 3. Low radiation: mainly relying on a special metal oxide layer to reduce the emissivity of the glass-air interface, thereby reducing heat transfer into the vehicle. However, since glass is a poor conductor of heat, neither heat absorption nor heat reflection methods can achieve rapid cooling. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a water-cooled glass assembly and system to improve the heat dissipation performance of the glass.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A water-cooled glass assembly includes an encapsulation glass and a water-cooling film disposed within the encapsulation glass; the water-cooling film is provided with microchannels, and the microchannels are arranged parallel to the surface of the encapsulation glass.

[0006] In an optional embodiment, a coolant conduit is further provided inside the encapsulation glass; the coolant conduit is arranged around the water-cooled film and communicates with the microchannel.

[0007] In an alternative embodiment, the microchannel includes a first subchannel and a second subchannel; viewed from the thickness direction of the water-cooled film, the first subchannel and the second subchannel interweave.

[0008] In an alternative embodiment, the first sub-channel and the second sub-channel are disposed on different layers of the water-cooled film.

[0009] In an optional embodiment, the first sub-channel and the second sub-channel are disposed on the same layer of the water-cooling film.

[0010] In an optional embodiment, the microchannel includes a groove formed on the surface of the water-cooling film, and / or a channel disposed within the water-cooling film.

[0011] In an optional embodiment, the encapsulation glass includes an outer glass layer and a sealing glass layer; the water-cooling film is disposed between the outer glass layer and the sealing glass layer; the thickness of the outer glass layer is greater than the thickness of the sealing glass layer.

[0012] In an optional embodiment, an adhesive protective layer is provided between the water-cooling film and the outer glass, and between the water-cooling film and the sealing glass.

[0013] In an optional embodiment, the outer glass comprises an outer glass sheet and an inner glass sheet stacked sequentially.

[0014] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0015] A water-cooled glass system includes a cooling mechanism and the aforementioned water-cooled glass assembly; the cooling mechanism is connected to a water-cooling film within the water-cooled glass assembly to form a water-cooling circulation path.

[0016] In an optional embodiment, the cooling mechanism includes a water-cooled pump and an air-cooled device; the water-cooled pump and the air-cooled device are sequentially connected to the water-cooled film to form a water-cooled circulation path.

[0017] In an optional embodiment, a vacuum generator is also included; the vacuum generator is connected to the outlet of the water-cooled membrane to provide negative pressure to the outlet of the water-cooled membrane.

[0018] The beneficial effects of this invention are as follows: by setting a water-cooling film inside the encapsulation glass, i.e., attaching the water-cooling film to the encapsulation glass; and by setting microchannels on the water-cooling film, the heat accumulated on the inner surface of the glass can be carried away by circulating coolant in the microchannels; since the specific heat capacity of the coolant is greater than that of air, compared with the heat dissipation methods in the prior art, the method of setting microchannels can achieve efficient heat dissipation and improve the heat dissipation performance of the glass.

[0028] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Current technologies, whether using methods like heat absorption, heat reflection, or low radiation, are inefficient at dissipating heat from glass. Especially in summer, in extreme cases, the inner surface temperature of car windows can reach as high as 90°C. Meanwhile, the number of vehicles designed without sunshades is increasing. Due to the lack of sunshades and the limited interior space, occupants have significantly more contact with the glass, potentially leading to accidental burns in certain situations.

[0030] Therefore, based on the aforementioned technical problems, this application provides a water-cooled glass assembly and system, which forms a water-cooled glass assembly by setting a water-cooling film with microchannels inside the encapsulated glass, and then connecting the water-cooled glass assembly with a cooling mechanism to form a water-cooling circulation path, thereby achieving efficient heat dissipation of the glass.

[0031] This application uses automotive sunroof glass as an example to introduce the structure and usage of a water-cooled glass assembly and system. The water-cooled glass assembly and system provided in this application are not only suitable for automotive glass, but also for other glass applications such as architectural glass. Specifically:

[0032] Please refer to Figure 1 A water-cooled glass system includes a cooling mechanism 2 and a water-cooled glass assembly 1. The cooling mechanism 2 is connected to a water-cooling film 12 within the water-cooled glass assembly 1 to form a water-cooling circulation path. By providing a water-cooling film 12 within the water-cooled glass assembly 1 and by providing microchannels 121 on the water-cooling film 12 that are connected to the cooling mechanism 2 to form a water-cooling circulation path, the heat accumulated on the inner surface of the glass can be carried away by the flow of coolant within the microchannels 121, thereby improving the heat dissipation performance of the glass.

[0033] In some examples, the cooling mechanism 2 includes a water-cooled pump 21 and an air-cooling device 22. The water-cooled pump 21 and the air-cooling device 22 are sequentially connected to the water-cooled film 12 to form a water-cooled circulation path. Specifically, the outlet of the water-cooled pump 21 is connected to the inlet of the microchannel 121 to provide high-pressure coolant to the microchannel 121. The inlet of the air-cooling device 22 is connected to the outlet of the microchannel 121, and the outlet of the air-cooling device 22 is connected to the inlet of the water-cooled pump 21. The air-cooling device 22 cools the incoming coolant, which carries heat, and then outputs it to the water-cooled pump 21 for further circulation and cooling. The high-pressure coolant provided by the water-cooled pump 21 creates a pressure difference between the inlet and outlet of the microchannel 121, making it easier for the coolant to flow. At the same time, by setting up the air-cooling device 22 to cool the coolant carrying heat, the coolant is recycled, providing continuous and effective heat dissipation for the glass.

[0034] In some examples, a vacuum generator 23 is also included; the vacuum generator 23 is connected to the outlet of the water-cooled film 12 to provide negative pressure to the outlet of the water-cooled film 12. That is, by providing negative pressure to the outlet of the water-cooled film 12 through the vacuum generator 23, a stable and effective pressure difference is formed between the inlet and outlet of the microchannel 121, ensuring the fluidity of the coolant in the microchannel 121, and further improving the heat dissipation effect of the cooling mechanism 2 on the glass.

[0035] Please refer to Figures 2-3 The aforementioned water-cooled glass assembly 1 includes an encapsulation glass 11 and a water-cooling film 12 disposed within the encapsulation glass 11. The water-cooling film 12 is provided with microchannels 121, and the microchannels 121 are arranged parallel to the surface of the encapsulation glass 11. Thus, the microchannels 121 distributed within the encapsulation glass 11 carry away heat from the inner surface of the encapsulation glass 11, reducing the temperature of the inner surface of the encapsulation glass 11, thereby reducing the risk of burns to personnel after contact with the glass.

[0036] In some instances, the microchannel 121 includes grooves formed on the surface of the water-cooling film 12 and / or channels disposed within the water-cooling film 12. That is, depending on the thickness of the water-cooling film 12 material and the manufacturing process, grooves or channels penetrating the water-cooling film 12 can be formed on or inside the water-cooling film 12 through processes such as etching or laser cutting, thereby forming the microchannel 121; at the same time, the number, shape, and size of the microchannels 121 can be designed according to actual conditions to meet the needs of different application scenarios.

[0037] In one optional embodiment, the microchannel 121 includes a first sub-channel 1211 and a second sub-channel 1212; viewed from the thickness direction of the water-cooling film 12, the first sub-channel 1211 and the second sub-channel 1212 interweave; and the first sub-channel 1211 and the second sub-channel 1212 are disposed on different layers of the water-cooling film 12; wherein, in one specific arrangement, the first sub-channel 1211 and the second sub-channel 1212 are respectively disposed on opposite sides of the surface of the water-cooling film 12, with multiple sets of longitudinal grooves forming the first sub-channel 1211 and multiple sets of transverse grooves forming the second sub-channel 1212. In another specific arrangement, the first sub-channel 1211 and the second sub-channel 1212 are both disposed on different layers within the water-cooling film 12, with multiple sets of penetrating longitudinal channels forming the first sub-channel 1211 and multiple sets of penetrating transverse channels forming the second sub-channel 1212. In another specific configuration, the first sub-channel 1211 is formed through a groove on the surface of the water-cooling film 12, and the second sub-channel 1212 is formed through a channel within the water-cooling film 12. By designing the microchannel 121 to include the first sub-channel 1211 and the second sub-channel 1212 disposed on different layers of the water-cooling film 12, i.e., the first sub-channel 1211 and the second sub-channel 1212 are not interconnected, allowing the coolant to flow separately within the first sub-channel 1211 and the second sub-channel 1212. This facilitates better control of the coolant flow direction, thereby improving the heat dissipation effect on the glass.

[0038] In another alternative embodiment, the microchannel 121 includes a first subchannel 1211 and a second subchannel 1212, which are disposed on the same layer of the water-cooling film 12. By designing the microchannel 121 to include the first subchannel 1211 and the second subchannel 1212 disposed on the same layer of the water-cooling film 12, i.e., the first subchannel 1211 and the second subchannel 1212 are interconnected, the microchannel 121 formed by the interconnection of the first subchannel 1211 and the second subchannel 1212 at the same layer can hold more coolant for the same thickness, thereby improving the heat dissipation effect on the glass by increasing the amount of coolant.

[0039] In the above-described embodiment of the water-cooled glass assembly 1, the number of sub-channels can be further increased depending on the thickness of the water-cooling film 12. That is, the microchannel 121 is formed by at least one sub-channel, which may include a first sub-channel 1211, a second sub-channel 1212, a third sub-channel, and so on. By increasing the number of sub-channels, the coverage area of ​​the microchannel 121 on the inner surface of the encapsulated glass 11 is increased, and the overall volume of the microchannel 121 is also increased, which can accommodate more coolant, thereby achieving a more effective heat dissipation effect.

[0040] In some examples, a coolant conduit 13 is also provided inside the encapsulation glass 11; the coolant conduit 13 surrounds the water-cooling film 12 and communicates with the microchannels 121. This allows the coolant to be delivered to different locations in the microchannels 121 after coolant is introduced through the inlet of the coolant conduit 13, filling the microchannels 121 with coolant; at the same time, the fact that the coolant conduit 13 surrounds the water-cooling film 12 improves the flowability of the coolant compared to simply placing the coolant conduit 13 at both ends of the water-cooling film 12, thereby achieving a more effective heat dissipation effect.

[0041] In some examples, the encapsulating glass 11 includes an outer glass layer 111 and a sealing glass 112; a water-cooling film 12 is disposed between the outer glass layer 111 and the sealing glass 112; the thickness of the outer glass layer 111 is greater than the thickness of the sealing glass 112. Because the external environment of the vehicle is relatively complex, making the thickness of the outer glass layer 111 greater than the thickness of the sealing glass 112 effectively protects and seals the water-cooling film 12.

[0042] In some examples, an adhesive protective layer 113 is provided between the water-cooling film 12 and the outer glass 111, and between the water-cooling film 12 and the sealing glass 112. That is, the water-cooling film 12 is bonded to the outer glass 111 and the sealing glass 112 at the places where they are attached, by means of the adhesive protective layer 113. Compared with directly attaching the water-cooling film 12 to the outer glass 111 and the sealing glass 112, the adhesive protective layer 113 further seals the water-cooling film 12, thereby improving the sealing performance of the microchannels 121 on the water-cooling film 12.

[0043] In some instances, the outer glass 111 comprises an outer glass pane 1111 and an inner glass pane 1112 stacked sequentially. By bonding the outer glass pane 1111 and the inner glass pane 1112 together to form the outer glass 111, the safety of the outer glass 111 is improved.

[0044] Example 1

[0045] Please refer to Figure 1 A water-cooled glass system includes a cooling mechanism 2 and a water-cooled glass assembly 1; the cooling mechanism 2 is connected to a water-cooling film 12 in the water-cooled glass assembly 1 and forms a water-cooling circulation path;

[0046] The cooling mechanism 2 includes a water-cooled pump 21, an air-cooling device 22, and a vacuum generator 23. The water-cooled pump 21, the water-cooled glass assembly 1, and the air-cooling device 22 are connected in sequence. Simultaneously, the vacuum generator 23 is connected to the outlet of the water-cooled film 12, providing negative pressure to the outlet of the water-cooled film 12. That is, pressure is applied through the inlet and outlet of the water-cooled film 12, causing the coolant to flow within the microchannel 121 under pressure. Specifically, the outlet of the water-cooled pump 21 is connected to the inlet of the microchannel 121. The outlet of the microchannel 121 is connected to the inlet of the air-cooling device 22, and the outlet of the air-cooling device 22 is connected to the inlet of the water-cooling pump 21. That is, the water-cooling pump 21 provides high-pressure coolant to the water-cooled glass assembly 1. When the coolant flows through the microchannel 121 on the water-cooling film 12 through the water-cooled glass assembly 1, it carries away the heat from the glass surface and flows into the air-cooling device 22. The air-cooling device 22 adopts an air-conditioning cooling system. The air conditioner cools the flowing coolant and then delivers it to the water-cooling pump 21 for recycling.

[0047] Please refer to Figures 2 to 4 The water-cooled glass assembly 1 includes an encapsulation glass 11, a water-cooling film 12 disposed within the encapsulation glass 11, and a coolant conduit 13. The encapsulation glass 11 includes an outer glass layer 111 and a sealing glass 112. The water-cooling film 12 is disposed between the outer glass layer 111 and the sealing glass 112 and is sealed by a sealing layer 14. The thickness of the outer glass layer 111 is greater than the thickness of the sealing glass 112. The sealing layer 14 can be formed using materials such as polyurethane adhesive. The water-cooling film 12 is provided with microchannels 121, and the microchannels 121 are arranged parallel to the surface of the encapsulation glass 11. The coolant conduit 13 is arranged around the water-cooling film 12 and communicates with the microchannels 121. An adhesive protective layer 113 is provided between the water-cooling film 12 and the outer glass layer 111, and between the water-cooling film 12 and the sealing glass 112. The adhesive protective layer 113 is made of PET (Polyethylene PET). The outer glass 111 comprises an outer glass 1111 and an inner glass 1112, which are sequentially stacked through a PVB (polyvinyl butyral) layer. The thickness of the outer glass 1111 and the inner glass 1112 is 2.1 mm, the thickness of the PVB layer 1113 is 0.76 mm, and the thickness of the sealing glass 112 is 0.7 mm. The thicknesses of the outer glass 1111, the inner glass 1112, the sealing glass 112, and the PVB layer 1113 can all be adjusted according to actual needs.

[0048] The microchannel 121 includes a groove formed on the surface of the water-cooling film 12, and / or a channel disposed within the water-cooling film 12. For details, please refer to... Figure 3The microchannel 121 includes a first subchannel 1211 and a second subchannel 1212. The first subchannel 1211 is composed of multiple sets of longitudinal grooves, and the second subchannel 1212 is composed of multiple sets of transverse grooves. The first subchannel 1211 and the second subchannel 1212 are perpendicular to each other in the thickness direction of the water-cooling film 12. In this embodiment, the first subchannel 1211 and the second subchannel 1212 are disposed on different layers of the water-cooling film 12. That is, the first subchannel 1211 can be disposed on the surface of the water-cooling film 12 near the outer glass 111, and the second subchannel 1212 can be disposed on the surface of the water-cooling film 12 near the sealing glass 112. The first subchannel 1211 and the second subchannel 1212 are not connected. Under the combined effect of the pressure difference on the opposite side and the capillary effect formed by the microchannel 121, the coolant carries away the heat accumulated on the inner surface of the glass.

[0049] Please refer to Figure 4 The coolant flows in the first sub-channel 1211 and the second sub-channel 1212 respectively; the overall flow direction of the coolant is from the inlet to the outlet. Based on this flow direction, the coolant can flow freely between the multiple sets of first sub-channels 1211, or the coolant can flow in the direction of the pressure difference by setting a pressure difference at both ends of each first sub-channel 1211. Figure 4 The direction indicated by the middle arrow is schematic; the actual flow direction of the coolant can be controlled in the manner described above.

[0050] In another optional embodiment, the first sub-channel 1211 and the second sub-channel 1212 are disposed on the same level of the water-cooled film 12; that is, the first sub-channel 1211 and the second sub-channel 1212 are interconnected. Although this makes the flow direction of the coolant in the microchannel 121 more complicated, since the first sub-channel 1211 and the second sub-channel 1212 are disposed on the same level, the microchannel 121 formed by the interconnection of the first sub-channel 1211 and the second sub-channel 1212 of the same thickness can hold more coolant, thereby improving the heat dissipation effect on the glass by increasing the amount of coolant.

[0051] In summary, this invention provides a water-cooled glass assembly and system, including a cooling mechanism and a water-cooled glass assembly. The cooling mechanism is connected to a water-cooling film within the water-cooled glass assembly to form a water-cooling circulation path. The water-cooled glass assembly includes an encapsulating glass and a water-cooling film disposed within the encapsulating glass. The water-cooling film is provided with microchannels, and the microchannels are arranged parallel to the surface of the encapsulating glass. By providing a water-cooling film within the water-cooled glass assembly and by providing microchannels on the water-cooling film that are connected to the cooling mechanism to form a water-cooling circulation path, the heat accumulated on the inner surface of the glass can be carried away by the flow of coolant within the microchannels, thereby improving the heat dissipation performance of the glass.
