Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a high-temperature heat-insulating fire door. Background Technology

[0002] During a fire, fire doors are crucial facilities for preventing the spread of fire and smoke, and their heat insulation and high-temperature resistance are of paramount importance.

[0003] However, traditional fire doors often fail to effectively block heat transfer when facing high-temperature fire scenes, causing the door temperature to rise rapidly. This not only affects the structural stability of the fire door but may also pose safety hazards such as burns to rescuers and escapees.

[0004] Traditional fire doors lack effective proactive cooling measures, making it difficult to quickly reduce the door's temperature in the early stages of a fire, thus limiting further improvements in their fire resistance. Therefore, developing a high-temperature insulated fire door that can effectively solve these problems is of significant practical importance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a high-temperature heat-insulating fire door, which solves the problem that traditional fire doors lack effective active measures for cooling and are difficult to quickly reduce the door temperature in the early stage of a fire, thus limiting the further improvement of their fire resistance performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature insulated fire door includes a fire door unit, wherein a cooling unit is provided within the fire door unit, and the fire door unit includes:

[0007] Door body;

[0008] A heat insulation layer is embedded in the door body;

[0009] The cooling unit includes:

[0010] The first serpentine tube is disposed inside the door body;

[0011] The second serpentine tube is disposed on one side of the first serpentine tube and is connected to the first serpentine tube.

[0012] A water inlet pipe, wherein the water inlet pipe is installed at one end of the first serpentine pipe;

[0013] The water outlet pipe is installed at one end of the second serpentine pipe, and the water outlet pipe has multiple water outlet holes at equal intervals.

[0014] Preferably, the fire door unit further includes:

[0015] The protective block is fixedly connected to the back of the door.

[0021] Preferably, the inlet of the water pipe is located on the front of the door.

[0022] This utility model discloses a high-temperature insulated fire door, which has the following beneficial effects:

[0023] This high-temperature insulated fire door is equipped with a cooling unit. Cooling water is injected into the first serpentine pipe through the inlet pipe. The cooling water circulates within the first and second serpentine pipes, absorbing the heat transferred from the door body. This circulation actively reduces the temperature of the fire door, further enhancing its fire resistance. When the cooling water flows to the outlet pipe, it is sprayed out through multiple equally spaced outlet holes, directly cooling the surface of the fire door. The sprayed water also forms a water film, further isolating heat transfer and improving the fire door's fire resistance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model discloses a high-temperature heat-insulating fire door.

[0032] Example 1: According to the appendix Figure 1-4 As shown, it includes a fire door unit 1, and a cooling unit 2 is installed inside the fire door unit 1. The fire door unit 1 includes:

[0033] Door 11;

[0034] Insulation panel 12 is embedded in door body 11;

[0035] Cooling unit 2 includes:

[0036] The first serpentine tube 21 is installed inside the door body 11;

[0037] The second serpentine tube 22 is disposed on one side of the first serpentine tube 21 and is connected to the first serpentine tube 21.

[0038] Water inlet pipe 23 is installed at one end of the first serpentine pipe 21;

[0039] The water outlet pipe 24 is installed at one end of the second serpentine pipe 22, and has multiple water outlet holes 241 evenly spaced apart. When cooling water flows to the water outlet pipe 24, it is sprayed out through the multiple water outlet holes 241, directly cooling the surface of the fire door. The sprayed water can also form a water film, further isolating heat transfer and improving the fire resistance of the fire door. In addition, the through hole 131 on the protective block 13 is connected to the water outlet holes 241, ensuring the uniformity and effectiveness of the spraying effect.

[0040] Furthermore, fire door unit 1 also includes:

[0041] Protective block 13 is fixedly connected to the back of door 11;

[0042] Door handle 14 is located on the front of door body 11 and is used to open and close the fire door.

[0043] Example 2: According to the appendix Figure 1-4 As shown, it includes a fire door unit 1, and a cooling unit 2 is installed inside the fire door unit 1. The fire door unit 1 includes:

[0044] Door 11;

[0045] Insulation panel 12 is embedded in door body 11;

[0046] Cooling unit 2 includes:

[0047] The first serpentine tube 21 is installed inside the door body 11;

[0048] The second serpentine tube 22 is disposed on one side of the first serpentine tube 21 and is connected to the first serpentine tube 21.

[0049] Water inlet pipe 23 is installed at one end of the first serpentine pipe 21;

[0050] The water outlet pipe 24 is installed at one end of the second serpentine pipe 22, and has multiple water outlet holes 241 equidistantly spaced. Cooling water is injected into the first serpentine pipe 21 through the water inlet pipe 23. The cooling water circulates within the first serpentine pipe 21 and the second serpentine pipe 22, absorbing the heat transferred from the door body 11, thus actively reducing the temperature of the fire door and further enhancing its fire resistance. When the cooling water flows to the water outlet pipe 24, it is sprayed out through the multiple water outlet holes 241 equidistantly spaced, directly cooling the surface of the fire door. The sprayed water can also form a water film, further isolating heat transfer and improving the fire resistance of the fire door.

[0051] Furthermore, the water outlet pipe 24 is embedded in the protective block 13. The setting of the protective block 13 not only enhances the structural stability of the door body 11, but also provides protection for the water outlet pipe 24. At the same time, the connection between the through hole 131 and the water outlet hole 241 ensures the spraying effect.

[0052] Furthermore, the protective block 13 has multiple through holes 131 at equal intervals, and the through holes 131 are connected to the water outlet 241.

[0053] Furthermore, the internal structure of the heat insulation panel 12 is a vacuum honeycomb structure. By embedding the heat insulation panel 12 with a vacuum honeycomb structure inside the door body 11, heat transfer is effectively isolated, the temperature of the door body 11 is reduced, and the heat insulation performance of the fire door is improved.

[0054] Furthermore, the first serpentine tube 21 and the second serpentine tube 22 are connected to form a double cooling layer.

[0055] Furthermore, the interface of the water inlet pipe 23 is located on the front of the door 11, which facilitates rapid connection to the water source in the event of a fire, enabling rapid cooling.

[0056] Working Principle: When a fire occurs, the high temperature environment puts immense heat transfer pressure on the fire door. At this time, the heat insulation layer 12 inside the fire door begins to function; its vacuum honeycomb structure effectively isolates heat transfer, reducing the temperature of the door body 11. Simultaneously, to further reduce the temperature of the door body 11, cooling water is injected into the first serpentine pipe 21 through the inlet pipe 23. The cooling water circulates within the first serpentine pipe 21 and the second serpentine pipe 22, absorbing the heat transferred from the door body 11. When the cooling water flows to the outlet pipe 24, it is sprayed out through multiple evenly spaced outlet holes 241, directly cooling the surface of the fire door. The sprayed water also forms a water film, further isolating heat transfer and improving the fire door's fire resistance. Furthermore, the through holes 131 on the protective block 13 are connected to the outlet holes 241, ensuring the uniformity and effectiveness of the spraying effect.
