Description

Technical Field

[0001] This utility model relates to the technical field of low-temperature air conditioning dehumidification equipment structure, and in particular to an inspection door. Background Technology

[0002] In the lithium battery industry, with the emergence of low-temperature regeneration, the front surface cooler is required to provide sufficiently low and dry air, thus the outlet air temperature of the front surface cooler has been gradually decreasing. However, during operation, it was found that when the outlet air temperature of the surface cooler section is ≤7℃, especially when the external ambient temperature is high, obvious condensation marks easily appear on the door frame and observation window of the dehumidifier. This is because the door frame of the maintenance door is segmented, and the segmented door frame has large joint gaps, which are prone to air leakage; moreover, the segmented door frame needs to be connected and assembled with screws, and screws have high thermal conductivity, which can easily cause cold bridges, thus causing condensation on the outside of the dehumidifier. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to improve the condensation on the outside of the inspection door.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an inspection door, including an integrated door frame, wherein the integrated door frame has an edge sleeved on the insulation board of the equipment body;

[0005] A door panel, which is mounted on an integrated door frame;

[0006] The sealing assembly includes a first sealing strip disposed between the insulation board of the equipment body and the edge banding, and a sealing element disposed between the integrated door frame and the door panel.

[0007] Furthermore, the sealing element includes a second sealing strip disposed on the integrated door frame, and a third sealing strip disposed on the door panel and pressed against the second sealing strip.

[0008] Furthermore, the integrated door frame has a first step, the door panel has a second step adapted to the first step, the second sealing strip is disposed on the first step, and the third sealing strip is disposed on the second step.

[0009] Furthermore, a first heat-insulating cavity is formed between the first step and the second step, and the volume of the first heat-insulating cavity is greater than the sum of the volumes of the second sealing strip and the third sealing strip.

[0010] Furthermore, the sealing element also includes a fourth sealing strip disposed on the integrated door frame, and a fifth sealing strip disposed on the door panel and pressed against the fourth sealing strip.

[0011] Furthermore, the integrated door frame has a third step, the door panel has a fourth step adapted to the third step, the fourth sealing strip is disposed on the third step, and the fifth sealing strip is disposed on the fourth step.

[0013] Furthermore, weather-resistant sealant is provided at the connection between the edging and the insulation board of the equipment body.

[0014] Furthermore, the door panel is provided with an observation window.

[0015] Furthermore, the observation window is a vacuum observation window.

[0016] The beneficial effects of this utility model are as follows: It replaces the segmented door frame with a one-piece door frame, thus avoiding the use of screws to assemble the door frame.

[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 5 As shown, this utility model discloses an inspection door, including an integrated door frame 1, a door panel 2, and a sealing assembly 3. The integrated door frame 1 has an edge band 11 fitted onto the equipment body insulation board 7; the door panel 2 is disposed on the integrated door frame 1; the sealing assembly 3 includes a first sealing strip 31 disposed between the equipment body insulation board 7 and the edge band 11, and a sealing element disposed between the integrated door frame 1 and the door panel 2.

[0029] Working principle: The integrated door frame 1 eliminates the need for assembling accessories such as the edging 11, avoiding gaps caused by assembly and preventing cold bridging caused by screws. Simultaneously, a first sealing strip 31 is added between the equipment body insulation board 7 and the edging 11 of the integrated door frame 1 to prevent air leakage between the edging 11 and the equipment body insulation board 7. A seal is also added between the integrated door frame 1 and the door panel 2 to prevent air leakage between them, thus effectively improving condensation on the exterior of the maintenance door.

[0030] It is worth noting that both the integrated door frame 1 and door panel 2 are made of low thermal conductivity materials to avoid cold bridging during maintenance. Specifically, the low thermal conductivity material is rubber-plastic foam.

[0031] Please refer to Figures 1 to 5 As shown, the sealing element further includes a second sealing strip 32 disposed on the integrated door frame 1, and a third sealing strip 33 disposed on the door panel 2 and pressed against the second sealing strip 32.

[0032] As can be seen from the above description, after the door panel 2 is closed, the mutual compression deformation of the second sealing strip 32 and the third sealing strip 33 can ensure the sealing between the integrated door frame 1 and the door panel 2.

[0033] Please refer to Figures 3 to 5As shown, the integrated door frame 1 further includes a first step 12, the door panel 2 includes a second step 21 adapted to the first step 12, the second sealing strip 32 is disposed on the first step 12, and the third sealing strip 33 is disposed on the second step 21.

[0034] As can be seen from the above description, the first step 12 and the second step 21 are used to increase the airflow path, thereby improving the sealing between the integrated door frame 1 and the door panel 2.

[0035] Please refer to Figures 1 to 5 As shown, the sealing element further includes a fourth sealing strip 34 disposed on the integrated door frame 1, and a fifth sealing strip 35 disposed on the door panel 2 and pressed against the fourth sealing strip 34.

[0036] As can be seen from the above description, after the door panel 2 is closed, the mutual compression deformation of the fourth sealing strip 34 and the fifth sealing strip 35 can further enhance the sealing between the integrated door frame 1 and the door panel 2.

[0037] Please refer to Figures 3 to 5 As shown, the integrated door frame 1 further includes a third step 13, the door panel 2 includes a fourth step 22 adapted to the third step 13, the fourth sealing strip 34 is disposed on the third step 13, and the fifth sealing strip 35 is disposed on the fourth step 22.

[0038] As described above, the third step 13 and the fourth step 22 are used to further increase the airflow path, thereby improving the sealing between the integrated door frame 1 and the door panel 2.

[0039] In some implementations, please refer to Figure 3 As shown, the first step 12 and the second step 21 enclose a first heat-insulating cavity 4, the volume of which is greater than the sum of the volumes of the second sealing strip 32 and the third sealing strip 33. After the door panel 2 is closed, the air in the remaining space of the first heat-insulating cavity 4 forms a natural insulating barrier. Because the thermal conductivity of air at room temperature (20℃) is 0.0267w / mk, which is much lower than the thermal conductivity of rubber and plastic foam (0.038w / mk) and the thermal conductivity of the sealing rubber strip (0.035w / mk), the door panel 2 has better heat insulation performance.

[0040] In some implementations, please refer to Figure 4As shown, the third step 13 and the fourth step 22 enclose a second heat-insulating cavity 5, the volume of which is greater than the sum of the volumes of the fourth sealing strip 34 and the fifth sealing strip 35. After the door panel 2 is closed, the air in the remaining space of the second heat-insulating cavity 5 forms a natural insulating barrier. Because the thermal conductivity of air at room temperature (20℃) is 0.0267w / mk, which is much lower than the thermal conductivity of rubber and plastic foam (0.038w / mk) and the thermal conductivity of the sealing rubber strip (0.035w / mk), the door panel 2 has better heat insulation performance.

[0041] In some implementations, please refer to Figure 5 As shown, the first step 12 and the second step 21 enclose a first heat-insulating cavity 4, the volume of which is greater than the sum of the volumes of the second sealing strip 32 and the third sealing strip 33; the third step 13 and the fourth step 22 enclose a second heat-insulating cavity 5, the volume of which is greater than the sum of the volumes of the fourth sealing strip 34 and the fifth sealing strip 35. After the door panel 2 is closed, the air in the remaining space of the first heat-insulating cavity 4 and the air in the remaining space of the second heat-insulating cavity 5 will form a natural insulating zone. Because the thermal conductivity of air at room temperature (20℃) is 0.0267w / mk, which is much lower than the thermal conductivity of rubber and plastic foam material (0.038w / mk) and the thermal conductivity of sealing rubber strip (0.035w / mk), the door panel 2 has better heat insulation performance.

[0042] Please refer to Figures 3 to 5 As shown, further, weather-resistant sealant 6 is provided at the connection between the edging 11 and the insulation board 7 of the equipment body.

[0043] As can be seen from the above description, the weather-resistant sealant 6 is used to further improve the sealing performance at the connection between the edge banding 11 and the equipment body insulation board 7.

[0044] Please refer to Figure 1 As shown, the door panel 2 is further provided with an observation window 23.

[0045] As can be seen from the above description, the addition of observation window 23 helps to observe the internal condition of the equipment.

[0046] Furthermore, the observation window 23 is a vacuum observation window.

[0047] As can be seen from the above description, the core feature of the vacuum observation window is that a vacuum space is formed between the two pieces of glass, which effectively isolates heat and avoids condensation caused by air bridging inside the observation window 23.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
