Description

Technical Field

[0001] This utility model relates to the field of metal enclosure technology, specifically a metal enclosure with fireproof function. Background Technology

[0002] Metal cladding panels, widely used in building exterior walls and roofs, are favored for their excellent durability, superior fire resistance, and ease of installation. These panels are primarily made of metal materials such as steel and aluminum. To further enhance their fire resistance, a double-layer metal panel design is typically employed, with a fire-resistant and heat-insulating material sandwiched between the two layers. This structure significantly improves the overall performance of the metal cladding panels.

[0003] The patent with publication number CN212506852U discloses a stainless steel-faced aluminum silicate composite fireproof board for use in spliced ​​enclosure structures. It includes a high-temperature deformation-resistant metal surface layer and an inorganic fireproof core layer. The high-temperature deformation-resistant metal surface layer is fixed to the inorganic fireproof core layer with stainless steel short nails, constraining the deformation of the metal panel at high temperatures and improving fire resistance, smoke insulation, and heat insulation. The use of non-magnetic stainless steel as the surface material of the stainless steel-aluminum silicate composite board improves the durability of the composite fireproof board. Stainless steel is easily processed into a snap-fit ​​structure, allowing for repeated assembly and disassembly. The stainless steel-aluminum silicate composite board can meet the requirements for the width of valve hall openings by adjusting the length of the core and surface materials, achieving seamless vertical splicing and only single-phase splicing. A grid-like receiving groove is fixed to the fireproof panel with stainless steel short nails, meeting the strength requirements of the composite fireproof board under large spans. Aluminum silicate fiber replaces commonly used rock wool, meeting the temperature requirements for transformer fires and effectively providing thermal and fire insulation.

[0004] However, the metal cladding panels in the above technology still have the following problems: Although aluminum silicate fiber is used to replace traditional rock wool to achieve fireproofing and thermal insulation, in the event of a fire, high temperature can still be transmitted through the metal layer on one side of the fireproof panel to the metal layer on the other side, thereby weakening its long-term thermal insulation performance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a metal enclosure panel with fireproof function, which improves the continuous thermal insulation performance of the metal enclosure panel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof metal enclosure panel, comprising a fireproof core layer and two metal surface layers. Cooling plates are fixedly connected to both sides of the fireproof core layer. The two cooling plates are fixedly connected to the two metal surface layers on the side away from the fireproof core layer. Each cooling plate has a cavity inside. Each cooling plate has a liquid injection hole communicating with the cavity on the side away from the fireproof core layer. The liquid injection hole extends to the outside of the metal surface layer.

[0007] Furthermore, a pipe communicating with the cavity is fixedly connected to one side of the cooling plate, and a splicing interface matching the pipe is opened through the other side of the cooling plate.

[0008] Furthermore, an annular groove is provided inside the splicing interface, and a sealing ring is slidably connected inside the annular groove.

[0009] Furthermore, a pressure relief valve is connected to the outside of the injection port.

[0010] Furthermore, one end of the pressure relief valve is fixedly connected to and connected to an external threaded pipe, which is threadedly connected to the injection hole.

[0011] Furthermore, the injection hole is located at the top of one side of the cooling plate.

[0012] Furthermore, the splicing interface is located at the bottom of one side of the cooling plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of fire-resistant metal enclosure panel, by setting a cooling plate with a cavity on the inside of the metal layer, can quickly absorb the high temperature of the metal layer through the cooling water in the cavity, thereby ensuring that the temperature of the metal layer will not be too high for a certain period of time and improving the thermal insulation performance of the metal enclosure panel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 A fireproof metal enclosure panel includes a fireproof core layer 1 and two metal surface layers 2. Cooling plates 3 are fixedly connected to both sides of the fireproof core layer 1. The two cooling plates 3 are fixedly connected to the two metal surface layers 2 on the side away from the fireproof core layer 1. Each cooling plate 3 has a cavity 301. Each cooling plate 3 has an injection hole 302 communicating with the cavity 301 on the side away from the fireproof core layer 1. The injection hole 302 extends to the outside of the metal surface layer 2.

[0024] like Figures 1 to 6 As shown, the fire-resistant metal enclosure panel of this utility model is structurally similar to existing metal enclosure panels. The main improvement of this utility model lies in further enhancing the thermal insulation performance of the metal enclosure panel, such as... Figures 1 to 6 As shown, in the present invention, the fire-resistant metal enclosure panel is used such that cooling water is injected into the cavity 301 of the cooling plate 3 through the injection hole 302. When a fire occurs, the metal surface layer 2 on the side closer to the fire source will continuously heat up. This temperature is transferred inward and then absorbed by the cooling water in the cavity 301, thereby preventing the metal surface layer 2 from heating up rapidly and further improving the thermal insulation performance of the metal enclosure panel. Before the cooling water in the cavity 301 evaporates completely, it can basically ensure that the inner fireproof core layer 1 will not be affected by excessively high temperatures. The evaporated water vapor can be discharged from the cavity 301 through the injection hole 302. The metal surface layer 2 also has perforations at the injection hole 302 position for injecting water into the cavity 301. The cooling water injected into the cavity 301 can be drinking water, distilled water, etc.

[0025] like Figures 1 to 6 As shown, a pipe 4 communicating with a cavity 301 is fixedly connected to one side of the cooling plate 3, and a splicing interface 303 matching the pipe 4 is provided through the other side of the cooling plate 3. When multiple metal enclosure panels are spliced ​​together, the pipe 4 on the side of the cooling plate 3 can be inserted into the splicing interface 303 on the side of another cooling plate 3, thereby realizing the interconnection of the cavities 301 in the two spliced ​​cooling plates 3, so as to better utilize the coolant in the cavity 301 for heat insulation and cooling in case of fire. It should be noted that if the splicing interface 303 and the pipe 4 on one side of the cooling plate 3 are not connected to other objects, rubber plugs, wooden plugs, etc. can be used to seal the splicing interface 303 and the pipe 4 to prevent the cooling water in the cavity 301 from leaking out. In addition, the end of the pipe 4 can also be set into a conical shape to facilitate the insertion of the pipe 4 into the corresponding splicing interface 303 more smoothly.

[0026] like Figure 4 As shown, an annular groove 304 is provided inside the splicing interface 303, and a sealing ring 5 is slidably connected inside the annular groove 304. When the through pipe 4 is inserted into the corresponding splicing interface 303, the sealing ring 5 inside the splicing interface 303 is squeezed into the annular groove 304 by the outer wall of the through pipe 4. The sealing ring 5 can be used to improve the sealing effect between the through pipe 4 and the splicing interface 303, thereby preventing the coolant from leaking into the cavity 301.

[0027] like Figures 1 to 6 As shown, a pressure relief valve 6 is connected to the outside of the injection hole 302. Installing the pressure relief valve 6 on the outside of the injection hole 302 allows the pressure inside the cavity 301 to gradually increase as the coolant absorbs heat and generates steam. Excess steam can be discharged from the cavity 301 through the pressure relief valve 6, thus preventing the cooling plate 3 from bulging. Simultaneously, the pressure relief valve 6 can also reduce the leakage of cooling water from the injection hole 302 within the cavity 301.

[0028] like Figure 5 and Figure 6 As shown, one end of the pressure relief valve 6 is fixedly connected to and connected to an external threaded pipe 7, which is threadedly connected to the injection hole 302. The pressure relief valve 6 can be easily disassembled and installed at the injection hole 302 via the external threaded pipe 7, so that coolant can be injected into the cavity 301 through the injection hole 302 when needed.

[0029] like Figures 1 to 6 As shown, the injection hole 302 is located on the top of one side of the cooling plate 3. Positioning the injection hole 302 on the top side of the cooling plate 3 facilitates the injection of coolant.

[0030] like Figures 1 to 6 As shown, the splicing interface 303 is located at the bottom of one side of the cooling plate 3. By setting the splicing interface 303 on the bottom side of the cooling plate 3, it is possible for the cooling water in the cavities 301 of the multiple spliced ​​and connected cooling plates 3 to flow through each other after multiple metal enclosure plates are spliced ​​together, thereby improving the overall thermal insulation effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
