Description

Technical Field

[0001] This invention relates to telecommunications equipment, and more particularly to telecommunications cabinets with improved hydrogen emissions. Background Technology

[0002] The purpose and construction of equipment enclosures for housing electronic and telecommunications equipment are well known. For example, as shown in Figures 1A-1B, an enclosure (or telecommunications cabinet) 10 is typically a rectangular box with side walls 13, a rear wall 14, a bottom plate 11, and a top plate 12. These telecommunications cabinets 10 are typically constructed with at least one sealed, weatherproof compartment in which equipment is housed within an internal cavity 15 of the cabinet 10. The cabinet 10 will have openings for access to one or more of its equipment compartments, and doors 20 for opening and closing over the openings. Telecommunications cabinets 10 are typically designed to prevent the ingress of dust, dirt, and water; however, overheating is one of the single greatest threats to the electronic equipment housed within the cabinet 10. Overheating of this electronic equipment can lead to potential malfunctions, failures, and unplanned, costly downtime. As is known to those skilled in the art, the performance of the equipment and the systems to which it is part will degrade as the equipment temperature increases. Consequently, manufacturers of these equipment enclosures, as well as telecommunications system manufacturers and suppliers, have been seeking methods to cool the equipment housed within these cabinets 10.

[0003] Because electronic cabinets house equipment that generates heat during operation, they typically include a thermal management or cooling system 50 (e.g., a heat exchanger) to prevent overheating. A common solution is to construct a cooling system 50 on the door 20 of the cabinet 10, the purpose of which is to draw ambient air from outside the cabinet 10 and circulate the air through the cabinet 10 for the purpose of cooling the equipment housed therein.

[0004] As described above, cabinet 10 houses electronic devices and telecommunications equipment and their components, including one or more batteries. During battery charging (e.g., lead-acid batteries), the electrolysis of water (H2O) in the electrolyte solution (e.g., sulfuric acid) can result in the generation of hydrogen gas (H2), which may be potentially explosive. Currently, some customers require cabinet 10 to have the ability to passively remove hydrogen from cabinet 10 (i.e., without using fans or similar devices). As shown in Figure 1A, to prevent hydrogen from accumulating within the internal cavity 15, cabinet 10 is provided with vents 60 in one or more sidewalls of sidewall 13.

[0005] As shown in Figure 1B, the vent 60 is positioned above the opening 13a in the side wall 13 of the cabinet 10 and secured to the side wall 13 via a fastening mechanism 67. In some cases, each vent 60 includes an inner plate 66 with a groove 66a corresponding to the opening 13a in the side wall 13 of the enclosure 10. The inner plate 66 may be positioned between two sealing members 64a, 64b. Each vent 60 also includes an outer cover plate 62 with louvers 63. The louvers 63 align with the groove 66 in the inner plate 66 (and the opening 13a in the side wall 13 of the cabinet 10). The vent 60 is designed to allow hydrogen to escape from the internal cavity 15 of the cabinet 10 while preventing dust, dirt, and water from entering. A more efficient method may be required to remove hydrogen from a telecommunications cabinet (or similar enclosure). Summary of the Invention

[0027] Embodiments of the present invention relate to a telecommunications cabinet with improved hydrogen venting. According to an embodiment of the invention, the telecommunications cabinet includes a channel integrated into a heat exchanger within the cabinet door. In some embodiments, a chimney effect facilitates the automatic venting of hydrogen from the internal cavity of the cabinet through the channel integrated into the heat exchanger and out of the cabinet. Reference will now be made to this further. Figures 2A to 4C Embodiments of the present invention will be described in more detail below.

[0028] refer to Figure 2A-2C The image shows a housing or communication cabinet 100 according to an embodiment of the present invention. Figure 2A The telecommunications cabinet 100 shown has a three-compartment configuration; however, embodiments of the invention may include a telecommunications cabinet with a single compartment (similar to the enclosure or telecommunications cabinet 10 described above and shown in Figures 1A-1B). Figure 2A and Figure 2C As shown, the telecommunications cabinet 100 is typically a rectangular box with side walls 113, a rear wall 114, a bottom plate 111, and a top plate 112. The telecommunications cabinet 100 also includes one or more doors 1201, 1202, 1203 (depending on the number of compartments), with one door 1201, 1202, 1203 corresponding to each compartment. Figure 2C As shown, these components together define an internal cavity 115 in which electronic devices and their components (e.g., battery 180) can be installed.

[0029] According to embodiments of the invention, each door 120 (which may be individually referred to herein as door 1201, 1202, 1203) may include an integrated cooling system 150 (which may be individually referred to herein as cooling system 1501, 1502, 1503). In some embodiments, each cooling system 1501, 1502, 1503 includes a heat exchanger. As described above, the cooling system 150 (i.e., the heat exchanger) is designed to control the climate of the telecommunications cabinet 100 (i.e., each compartment of the cabinet) by drawing ambient air from outside the cabinet 100 and circulating the air through the internal cavity 115 of the cabinet 100 for the purpose of cooling the equipment housed therein. The use of heat exchangers for cooling the electronic devices housed in the telecommunications cabinet is generally known to those skilled in the art and therefore will not be discussed further herein. See, for example, U.S. Patent No. 10,830,541 granted to Hendrix et al. and Chinese Invention Application No. 202411290706.6 (Outdoor Wireless Networks LLC).

[0030] As discussed above, since the telecommunications cabinet 100 houses equipment that generates heat during operation, a cooling system 150 (e.g., a heat exchanger) is used to help prevent the equipment from overheating. In some embodiments, the cooling system 150 (and the corresponding door 120) may include one or more sets of openings 152, 154 configured and positioned to allow heated air (i.e., air within the internal cavity 115 of the cabinet 100, heated by the operation of the electronics housed therein) to vent from the internal cavity 115 of the telecommunications cabinet 100 and exit the cabinet 100. For example, as Figure 2B As shown, in some embodiments, a first plurality of openings 152 are provided in at least one sidewall of the cooling system (heat exchanger) 150, and a second plurality of openings 154 are provided in the inner surface of the corresponding door 120, the inner surface providing a flow path into the outer loop of the cooling system 150.

[0031] According to some embodiments of the invention, the hydrogen venting system 160 may be included in the cooling system 150 and / or door 120 of the telecommunications cabinet 100. In some embodiments, the hydrogen venting system 160 is configured to automatically vent hydrogen (H2) (e.g., hydrogen generated by the battery 180 housed therein) from the internal cavity 115 of the cabinet 100 (see, for example, Figures 3A-3F and Figures 4A-4C In other words, in some embodiments, the hydrogen evacuation system 160 is configured to passively remove hydrogen from the internal cavity 115 of the cabinet 100 when the fan (or other similar device) of the cooling system 150 is not in operation. According to an embodiment of the invention, the hydrogen evacuation system 160 includes one or more channels 156 connecting a second plurality of openings 154 to a first plurality of openings 152. The one or more channels 156 are integrated into the cooling system 150 and / or the door 120 to create a flow path F for the hydrogen (H2) to be removed from the telecommunications cabinet 100. H (See example) Figures 3A-3F and Figures 4A-4C In some embodiments, one or more channels 156 may be included in an open space present within the door 120. For example, in some embodiments, the channel 156 may be located near the sidewall of the cooling system 150 and / or the door 120. As described in further detail below, in some embodiments, the flow path F formed by one or more channels 156 H Configured to utilize ambient (external) airflow F drawn into the cooling system 150 of the telecommunications cabinet 100 A And the "chimney effect" provided by the operation of the cooling system.

[0032] refer to Figures 3A-3F An exemplary flow path F of hydrogen gas leaving telecommunications cabinet 100 according to an embodiment of the present invention is shown. H As discussed above, according to embodiments of the invention, a hydrogen exhaust system 160 including one or more channels 165 may include one or more of the cooling system (i.e., heat exchanger) 150 and / or doors 120 of the telecommunications cabinet 100 to facilitate the propulsion of hydrogen F H (For example, hydrogen gas generated by charging the battery 180 housed therein) flows from the internal cavity 115 and out of the telecommunications cabinet 100. Figure 3C As shown, in some embodiments, the hydrogen venting system 160 may further include a third plurality of openings 156 disposed in the bottom end 161 of the cooling system 150 (or door 120). According to embodiments of the invention, one or more channels 165 of the hydrogen venting system 160 are arranged in fluid communication with at least one of the first plurality of openings 152, the second plurality of openings 154 and / or the third plurality of openings 156 in the corresponding cooling system 150 and door 120 of the cabinet 100.

[0033] According to an embodiment of the invention, a third plurality of openings 156 located at the bottom end of the cooling system 150 or door 120 are configured to allow ambient air F A It flows into one or more corresponding channels 165 connected to it. For example... Figure 3B and Figure 3D-3E As shown, in some embodiments, ambient air F A The hydrogen F flows upward through one or more channels 156, which intersect and / or connect with one or more additional channels 156. H After entering through the second plurality of openings 154, hydrogen flows from the internal cavity 115 of the cabinet 100 through the one or more additional channels. In some embodiments, one or more fans (not shown) of the cooling system 150 may help to draw (or suck) hydrogen F from the internal cavity 115. H The flow passes through the second plurality of openings 154 and enters one or more channels 156 of the hydrogen discharge system 160.

[0034] like Figure 3B and Figure 3D-3E As shown, according to an embodiment of the invention, one or more channels 165 and openings 152, 154, 156 of the hydrogen venting system 160 integrated into the cooling system 150 and door 120 of the cabinet 100 are configured together to produce a “chimney effect”, which facilitates the automatic venting of hydrogen (H2) from the internal cavity 115 and out of the cabinet 100.

[0035] The "chimney effect" is a natural phenomenon in which air moves vertically through a structure due to a temperature difference, causing warm air to rise and cold air to sink. The chimney effect occurs when warm air, which is less dense than cold air, rises, creating a pressure difference that draws in cooler air from a lower level. In the hydrogen exhaust system 160 of this invention, the chimney effect is utilized by the external ambient air F... A Hydrogen gas flows upward from opening 156 into the cooling system 150 and is generated by heated air (i.e., heated by the operation of the electronic devices housed therein) within the internal cavity 115 of the cabinet 100. Since hydrogen (H2) is the lightest element, the hydrogen gas produced by the battery 180 will naturally rise within the internal cavity 115 of the cabinet 100. Hydrogen F HThe flow will also follow the upward flow of warm air within the internal cavity 115 (generated by the operation of other telecommunications equipment housed therein), thereby allowing hydrogen (H2) to be automatically discharged from the cabinet 100 through the opening 152 (i.e., without the need for a fan). In some embodiments, there are no additional openings (i.e., vents) above the second plurality of openings 154 within the internal cavity 115, and as a result, a chimney effect will create a pressure difference between the door 120 and the internal cavity 115 to draw hydrogen from the internal cavity 115 and into one or more channels 165, and discharge it from the cabinet 100.

[0036] In some embodiments, the hydrogen venting system 160 further includes a fourth plurality of openings 158 added to the cooling system 1501 and / or the door 1201. Figure 3E and Figure 3F As shown, in some embodiments, a fourth plurality of openings 158 may be provided in the upper section of the cooling system 150 or the door 120. In some embodiments, one or more channels 165 are further in fluid communication with the fourth plurality of openings 158, thereby providing for hydrogen F H An additional outlet exits from the telecommunications cabinet 100. In some embodiments, the hydrogen venting system 160 may also include one or more additional structures (e.g., baffles) and / or additional vents (i.e., openings) to facilitate the flow of hydrogen F H The fluid flows out of the internal cavity 115 and into one or more channels 165 to be removed from the cabinet 100.

[0037] refer to Figures 4A-4C The flow path F of hydrogen gas leaving the telecommunications cabinet 100 according to an embodiment of the present invention is further illustrated. H .like Figure 4B-4C As shown and as described above, the hydrogen (H2) generated by the battery 180 rises naturally within the internal cavity 115 of the cabinet 100. In some embodiments, when the door 120 of the cabinet 100 is closed, the internal cavity 115 has no openings or vents above the plane PP, causing the generated hydrogen (H2) to accumulate in the section of the internal cavity 115 that houses the battery 180. In some embodiments, external air F enters the cooling system 150 (i.e., through the third plurality of openings 156). A The chimney effect creates a pressure difference that helps to draw (pump) hydrogen (H2) (e.g., hydrogen (H2) that has risen above the plane PP) through opening 154 and out of the internal cavity 115 of cabinet 100. Figure 4B-4C As further shown in the figure, hydrogen F H Flow (with outside air F) A It continues through one or more channels 165 integrated into the cooling system 150 and / or door 120, and exits the cabinet 100 through openings 152 and / or openings 158.

[0038] As described herein, aspects of the present invention relate to a method for discharging hydrogen (H2) from a telecommunications cabinet 100, the method comprising the steps of: generating hydrogen (H2) from at least one battery 180 housed in an internal cavity 115 of the telecommunications cabinet 100; operating a cooling system 150 located within a door 120 of the telecommunications cabinet 100; and allowing the hydrogen (H2) generated by the at least one battery 180 to pass through the door 120 to remove hydrogen (H2) from the telecommunications cabinet 100.

[0039] The foregoing description is a description of the invention and should not be construed as limiting it. Although several exemplary embodiments of the invention have been described, those skilled in the art will readily understand that many modifications may be made to the exemplary embodiments without substantially departing from the novel teachings and advantages of the invention. Therefore, all such modifications are intended to be included within the scope of the invention as defined in the claims. The invention is defined by the appended claims, and equivalents of the claims are included therein.
