Definitions
- the present invention relates to an exhaust system for electrical equipment enclosures and, more particularly, to a top cover for electronic equipment enclosures which provide better thermal insulation and noise abatement as well as other benefits.
- Some types of electronic or related equipment are typically located out of doors. Examples are telecommunications equipment and cable television or data equipment. Often this class of equipment is referred to as “outside plant equipment” and/or “remote terminals.” Also, it is well know that this equipment generates excessive heat and undesirable gas. Further, this outside plant equipment may be located just about any place on the planet, in very warm, cold, wet, dry, and high wind climates and at high and low altitudes.
- an equipment enclosure comprising front, rear and side portions and an interior chamber, a heat exchanger mounted within the interior chamber, a centrifugal fan mounted to the heat exchanger for drawing ambient air, the fan being separated from the interior chamber, a top cover forming a fan casing for the centrifugal fan mounted to the front and rear portions, the top cover including oppositely disposed passageways extending from the fan casing to a periphery of the top cover, and an air chamber in the top cover.
- An object of the present invention is to provide a cover for electronic equipment enclosures which has good thermal insulation qualities, good acoustical suppression qualities and sufficient strength for effective use.
- Another aim of the present invention is to provide a cover for electronic equipment enclosures which is relatively easy and inexpensive to manufacture and which is easy to assemble with the remainder of an enclosure.
- Still another advantage of the present invention is to provide a cover for electronic equipment enclosures which is relatively light in weight.
- Further aspects of the present invention are to provide a cover which controls rain water runoff and which handles high wind conditions through the use of a dual exit for heat exchanger exhaust.
- Yet still other objects of the present invention are to provide a more powerful heat exchanger and an exhaust system that prevents blockage of the exhaust air from the heat exchanger.

- An electronic equipment enclosure or cabinet typically is a free standing box-like structure located out-of-doors where it is bolted to a concrete slab and where it is exposed to the sun, rain, wind and other environmental and climatic elements.
- These enclosures or cabinets are designed to house a variety of electronic equipment, for example, digital loop carriers, fiber optic transport systems, radio equipment for wireless applications, and remote power systems as well as telephone equipment. Because the enclosure is situated out-of-doors, there is a need to be concerned about such matters as high temperatures and direct exposure to the sun on the one hand and hurricane weather on the other as well as impacts from such items as bullets and pellets.
- an enclosure 10 having a front wall 12 with two access doors 14 and 16 , a pair of sidewalls, such as the wall 18 , and a rear wall 20 also having two access doors (not shown).
- the enclosure includes a top cover 22 .
- the enclosure includes a sealed upper chamber 24 for the electronic equipment and a back-up battery lower chamber 26 which is open to ambient air.
- the back-up battery 28 is useful should there be an electrical outage.
- the electronic equipment, fiber optics, radio equipment or the like 30 , 31 is located in the sealed upper chamber 24 attached to racks that also provide a frame for the enclosure.
- the enclosure is also provided with a heat exchanger 32 because the electronic equipment generates heat. Heat build up may also be caused by solar impingement. As shown in FIG.
- the heat exchanger draws in outside air represented by the arrows 34 through louvers 35 into the bottom chamber 26 and into the heat exchanger 32 .
- This intake of outside air is accomplished by a powerful centrifugal fan 36 at the top of the heat exchanger.
- the air is then passed through an exhaust duct 38 and exhausted to the ambient air through a screen 40 as depicted by the arrow 42 .
- This movement of air in addition to supplying cool air to the heat exchanger, also ventilates the lower chamber 26 to prevent any undesirable gas or heat build-up from the batteries 28 .
- the heat exchanger 32 is known as a dual air, vertical flow device. Heated air from the sealed upper chamber 24 represented by the phantom curves 44 , 45 travels in a circular pattern where it is cooled in the heat exchanger. This heated air from the equipment in the sealed upper chamber is sucked through openings 46 , 48 in the upper portion of the heat exchanger and then is drawn downwardly by fans 50 , 51 at the bottom of the heat exchanger. In the process, heat is transferred from the hot, downwardly moving equipment air to the cool upwardly moving ambient air. The cooled equipment air is exhausted through vents 52 , 54 near the bottom of the heat exchanger 32 . As can be appreciated, the equipment air from the sealed chamber 24 never mixes with the cooling ambient air.
- the present invention involves an improved top cover 22 that provides for a more effective and efficient cabinet.
- the cover 22 has an upper panel 58 , FIG. 3 of synthetic resin material with a length represented by the line 60 , a width represented by the line 62 , an edge portion 64 and a periphery 66 .
- the top cover also includes a lower panel 70 , FIG. 4, made of a similar synthetic resin material and having generally the same or very similar length 72 , width 74 , edge portion 76 , FIG. 6, and periphery 78 as the upper panel 58 .
- the upper panel includes an additional layer or “cap stock” to provide UV protection. Typically, the bottom panel does not need such a layer.
- the upper panel and the lower panel are sealed together by ultrasonic welding at their edge portions 64 , 76 , FIG. 6. By doing this, an air chamber 79 is formed which helps the top cover to act as a thermal insulator to solar impingement.
- Two access ports 80 , 82 are provided in the top cover (FIGS. 3 and 4) to allow access to the heat exchanger fans, such as the fan 36 , FIG. 2. These access ports are covered with lids, such as a lid 84 , FIG. 3. If there is a need to service or replace the heat exchanger fans, this can be easily accomplished by removing the lids to expose the fans.
- a rim 85 around the access port 82 is shown in more detail.
- the rim includes a groove 86 located just outwardly of the port.
- the groove is present to seat an O-ring seal for weatherproofing the port.
- a fastener sleeve 88 for receiving a fastener, such as a screw (not shown), that goes through a fastener opening 90 , FIG. 3 of the lid 84 .
- the weather sealing of the port becomes effective when the lid 84 is tightened downwardly by fasteners on the seal located in the groove 86 .
- seals may be ethylene propylene diene methylene or “EPDM” and is well known by those skilled in the sealing art.
- EPDM ethylene propylene diene methylene
- the material of the upper and lower panels may be of a PVC blend sold under the Royalite R 87/59 brand by Spartech of South Bend, Ind.
- the upper panel 58 has an upper surface 92 which has a slightly bowed shape across its width.
- the upper panel may also have a slightly bowed shape across its length.
- the bowed shape ensures that rainwater will run off the cover toward the periphery 66 .
- length-wise extending berms 100 , 102 , FIGS. 3, 5 and 6 are provided at the periphery which extend almost the entire length of the cover as shown in FIG. 3.
- the berms provide a barrier to the flow of rainwater.
- Another pair of parallel berms 104 , 106 extend along most of the width of the cover. This arrangement leaves four corner portions 110 , 112 , 114 and 116 without a berm or barrier to the flow of rainwater. Thus, a technician working with the electronics equipment in the upper chamber 24 through an open set of doors will not be exposed to runoff rainwater during a rain storm. Instead, the water will be directed to one or more of the four comer portions before dropping to the ground.
- the lower panel 70 is shown to have a very uneven surface so that in numerous sectional views, the lower panel has a corrugated profile.
- portions of the lower panel have low horizontal surfaces such as the surface 120 and high horizontal surfaces such as the surface 122 .
- the lower panel also has generally vertically disposed surfaces such as the surface 124 .
- Two lateral passageways or ducts 150 , 152 , FIG. 4, are formed in the lower panel in the immediate vicinity of the two access ports 80 , 82 .
- Two scroll fan casings 147 , 149 are also formed in the lowe panel around the two access ports. Beneath the access ports are centrifugal fans, such as the fan 36 . These fans are more powerful than those previously used and thus, provide more effective heat exchange. The fans are positioned so as to rotate about a vertical axis and exhaust air in a horizontal direction. When the cover is attached to the rest of the cabinet, the centrifugal fans push the exhaust air from the heat exchanger to the right when viewed in FIG.
- the heat exchanger fans are capable of operating even under severe weather conditions. Also, if the high winds are accompanied by heavy rain, water may be driven through the screens 154 , 156 and into the passageways 150 , 152 . Providing the oppositely directed passageways 151 , 153 allows the water to be driven through the cover instead of being forced into the cabinet through the fan. This flow by-pass arrangement means there will be no water build up or leakage.
- a suitable centrifugal fan may be acquired from EBM/Papst of Farmington, Conn.
- the fan diameter is about 225 mm (or just under 9 inches) with a capacity of about 300 cfm at a pressure of one inch of water.
- the upper and lower panels are made from the PVC blend mentioned above and are thermoformed. Molded stiffening members may be included during the forming operation to strengthen the cover. Wall thickness after forming is about 0.100 inches whereas the thickness of the panels before forming are about 0.125 inches.
- the length and width of the cover may vary depending upon the size of the cabinet; currently, the length may vary between 42 and 90 inches, and the width may be about 46.5 inches.
- the height of the cover (without lids) may be about 2.6 inches.
- the diameter of the access ports is about 14 inches.
- the exhaust air/water ducts may be about 5.5 inches wide.
- the inventive top cover provides efficient and effective thermal insulation as well as noise suppression. This is because of such features as the air space between the upper and lower panels and the use of synthetic resin which is inherently more dense than metal so as to resonate at a much higher frequency than metal.
- the inventive top cover has an air/water exhaust and a flow by-pass duct system that allows the heat exchanger fans to operate even under severe high pressure and wet circumstances.
- the top cover has good strength characteristics and once capital expenditures are made, is easy to fabricate and handle because of the relatively low weight. With regard to manufacturing and assembly, a major advantage is that there will be no need to go through a complicated welding, machining and painting operation. Furthermore, since the panels are molded, it is easy to include the rain barrier berms for directing the rain out of the way of the access doors in the front and rear walls.
Abstract
Description
- This is a divisional patent application of copending patent application Ser. No. 09/548,043, filed Apr. 12, 2000.
- 1. Field of the Invention
- The present invention relates to an exhaust system for electrical equipment enclosures and, more particularly, to a top cover for electronic equipment enclosures which provide better thermal insulation and noise abatement as well as other benefits.
- 2. Description of the Related Art
- Some types of electronic or related equipment are typically located out of doors. Examples are telecommunications equipment and cable television or data equipment. Often this class of equipment is referred to as “outside plant equipment” and/or “remote terminals.” Also, it is well know that this equipment generates excessive heat and undesirable gas. Further, this outside plant equipment may be located just about any place on the planet, in very warm, cold, wet, dry, and high wind climates and at high and low altitudes.
- Over the last several years specialized enclosures or cabinets have been engineered to form a protective environment for the outside plant equipment. Presently, such electronic equipment enclosures or cabinets are constructed with all metal outer panels, a weather sealed chamber for some of the equipment and non-sealed chambers for other portions of the equipment. The metal panels, however, have relatively poor thermal insulation qualities and noise abatement characteristics. When steps are taken to alleviate these problems, costs of manufacture and assembly increase prohibitively. Even without these steps, steel or aluminum panels are expensive and unnecessarily heavy.
- The general design of the metal cabinets, and especially heat exchange units located within the cabinets for cooling the heat generated by the equipment, may be appreciated by reference to U.S. Pat. Nos. 5,832,988 and 5,570,740. The climatic and human problems faced by the industry and vendor requirements generated to protect this outside plant equipment are explained in those patents. Important steps have been take to alleviate some problems but problems remain nevertheless.
- The present invention improves upon the metal covers now being used for equipment cabinets and a number of advantages are achieved by the improvement. What is described here is an equipment enclosure comprising front, rear and side portions and an interior chamber, a heat exchanger mounted within the interior chamber, a centrifugal fan mounted to the heat exchanger for drawing ambient air, the fan being separated from the interior chamber, a top cover forming a fan casing for the centrifugal fan mounted to the front and rear portions, the top cover including oppositely disposed passageways extending from the fan casing to a periphery of the top cover, and an air chamber in the top cover.
- An object of the present invention is to provide a cover for electronic equipment enclosures which has good thermal insulation qualities, good acoustical suppression qualities and sufficient strength for effective use. Another aim of the present invention is to provide a cover for electronic equipment enclosures which is relatively easy and inexpensive to manufacture and which is easy to assemble with the remainder of an enclosure. Still another advantage of the present invention is to provide a cover for electronic equipment enclosures which is relatively light in weight. Further aspects of the present invention are to provide a cover which controls rain water runoff and which handles high wind conditions through the use of a dual exit for heat exchanger exhaust. Yet still other objects of the present invention are to provide a more powerful heat exchanger and an exhaust system that prevents blockage of the exhaust air from the heat exchanger.
- A more complete understanding of the present invention and other objects, aspects, aims and advantages thereof will be gained from a consideration of the following description of the preferred embodiment read in conjunction with the accompanying drawings provided herein.
- FIG. 1 is a front perspective view of an electronic equipment enclosure.
- FIG. 2 is a diagrammatic side elevational view of the enclosure of FIG. 1.
- FIG. 3 is a top isometric view of an enclosure cover.
- FIG. 4 is a bottom isometric view of the cover shown in FIG. 3.
- FIG. 5 is a sectional, side elevational view of the cover taken along line5-5 of FIG. 3.

- While the present invention is open to various modifications and alternative constructions, the preferred embodiment shown in the drawings will be described herein in detail. It is understood, however, that there is no intention to limit the invention to the particular form disclosed. On the contrary, the intention is to cover all modifications, equivalent structures and methods, and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.
- An electronic equipment enclosure or cabinet typically is a free standing box-like structure located out-of-doors where it is bolted to a concrete slab and where it is exposed to the sun, rain, wind and other environmental and climatic elements. These enclosures or cabinets are designed to house a variety of electronic equipment, for example, digital loop carriers, fiber optic transport systems, radio equipment for wireless applications, and remote power systems as well as telephone equipment. Because the enclosure is situated out-of-doors, there is a need to be concerned about such matters as high temperatures and direct exposure to the sun on the one hand and hurricane weather on the other as well as impacts from such items as bullets and pellets. Referring now to FIGS. 1 and 2, there is illustrated such an
enclosure 10 having afront wall 12 with twoaccess doors wall 18, and arear wall 20 also having two access doors (not shown). In addition, the enclosure includes atop cover 22. The enclosure includes a sealedupper chamber 24 for the electronic equipment and a back-up batterylower chamber 26 which is open to ambient air. The back-upbattery 28 is useful should there be an electrical outage. The electronic equipment, fiber optics, radio equipment or the like 30, 31 is located in the sealedupper chamber 24 attached to racks that also provide a frame for the enclosure. The enclosure is also provided with aheat exchanger 32 because the electronic equipment generates heat. Heat build up may also be caused by solar impingement. As shown in FIG. 2, the heat exchanger draws in outside air represented by thearrows 34 throughlouvers 35 into thebottom chamber 26 and into theheat exchanger 32. This intake of outside air is accomplished by a powerfulcentrifugal fan 36 at the top of the heat exchanger. The air is then passed through anexhaust duct 38 and exhausted to the ambient air through ascreen 40 as depicted by thearrow 42. This movement of air, in addition to supplying cool air to the heat exchanger, also ventilates thelower chamber 26 to prevent any undesirable gas or heat build-up from thebatteries 28. - The
heat exchanger 32 is known as a dual air, vertical flow device. Heated air from the sealedupper chamber 24 represented by thephantom curves openings fans vents heat exchanger 32. As can be appreciated, the equipment air from the sealedchamber 24 never mixes with the cooling ambient air. - Each part of the
enclosure 10 should be specifically designed to create an efficient and effective cabinet structure. The present invention involves an improvedtop cover 22 that provides for a more effective and efficient cabinet. Thecover 22 has anupper panel 58, FIG. 3 of synthetic resin material with a length represented by theline 60, a width represented by theline 62, anedge portion 64 and aperiphery 66. The top cover also includes alower panel 70, FIG. 4, made of a similar synthetic resin material and having generally the same or verysimilar length 72,width 74,edge portion 76, FIG. 6, andperiphery 78 as theupper panel 58. The upper panel includes an additional layer or “cap stock” to provide UV protection. Typically, the bottom panel does not need such a layer. - The upper panel and the lower panel are sealed together by ultrasonic welding at their
edge portions air chamber 79 is formed which helps the top cover to act as a thermal insulator to solar impingement. Twoaccess ports fan 36, FIG. 2. These access ports are covered with lids, such as alid 84, FIG. 3. If there is a need to service or replace the heat exchanger fans, this can be easily accomplished by removing the lids to expose the fans. - Referring to FIG. 8, a
rim 85 around theaccess port 82 is shown in more detail. The rim includes agroove 86 located just outwardly of the port. The groove is present to seat an O-ring seal for weatherproofing the port. Beyond thegroove 86 in a radial direction is afastener sleeve 88 for receiving a fastener, such as a screw (not shown), that goes through afastener opening 90, FIG. 3 of thelid 84. The weather sealing of the port becomes effective when thelid 84 is tightened downwardly by fasteners on the seal located in thegroove 86. - To maintain weather tightness of the sealed
chamber 24, another seal or gasket (not shown) is provided between the upper edges of the front and side walls and thelower panel 70. All doors also have peripheral seals. The material of the seals may be ethylene propylene diene methylene or “EPDM” and is well known by those skilled in the sealing art. The material of the upper and lower panels may be of a PVC blend sold under the Royalite R 87/59 brand by Spartech of South Bend, Ind. - Referring now to FIG. 5, the
upper panel 58 has anupper surface 92 which has a slightly bowed shape across its width. The upper panel may also have a slightly bowed shape across its length. The bowed shape ensures that rainwater will run off the cover toward theperiphery 66. To prevent rainwater from coming down in front of theaccess doors front wall 12 or the doors of therear wall 20, length-wise extendingberms parallel berms corner portions upper chamber 24 through an open set of doors will not be exposed to runoff rainwater during a rain storm. Instead, the water will be directed to one or more of the four comer portions before dropping to the ground. - Referring now to FIGS. 4, 5 and7, the
lower panel 70 is shown to have a very uneven surface so that in numerous sectional views, the lower panel has a corrugated profile. For example, portions of the lower panel have low horizontal surfaces such as thesurface 120 and high horizontal surfaces such as thesurface 122. In addition, the lower panel also has generally vertically disposed surfaces such as thesurface 124. By repeating this pattern of corrugation, the strength of the lower panel is greatly enhanced. At the same time, theair chamber 79 is still maintained for purposes of thermal insulation. - Six
fastener openings periphery 78 so when assembled, the top cover may be attached to the remainder of the enclosure from within the enclosure. Thus, there are no attachment openings or fasteners exposed to the weather or for tampering. - Four
additional fastener openings - Two lateral passageways or
ducts access ports scroll fan casings fan 36. These fans are more powerful than those previously used and thus, provide more effective heat exchange. The fans are positioned so as to rotate about a vertical axis and exhaust air in a horizontal direction. When the cover is attached to the rest of the cabinet, the centrifugal fans push the exhaust air from the heat exchanger to the right when viewed in FIG. 4, through thepassageways stainless steel screens ducts passageways stainless steel screens screens screens passageways passageways - A suitable centrifugal fan may be acquired from EBM/Papst of Farmington, Conn. The fan diameter is about 225 mm (or just under 9 inches) with a capacity of about 300 cfm at a pressure of one inch of water.
- The upper and lower panels are made from the PVC blend mentioned above and are thermoformed. Molded stiffening members may be included during the forming operation to strengthen the cover. Wall thickness after forming is about 0.100 inches whereas the thickness of the panels before forming are about 0.125 inches. The length and width of the cover may vary depending upon the size of the cabinet; currently, the length may vary between 42 and 90 inches, and the width may be about 46.5 inches. The height of the cover (without lids) may be about 2.6 inches. The diameter of the access ports is about 14 inches. The exhaust air/water ducts may be about 5.5 inches wide.
- It can now be readily appreciated that the inventive top cover provides efficient and effective thermal insulation as well as noise suppression. This is because of such features as the air space between the upper and lower panels and the use of synthetic resin which is inherently more dense than metal so as to resonate at a much higher frequency than metal. In addition, the inventive top cover has an air/water exhaust and a flow by-pass duct system that allows the heat exchanger fans to operate even under severe high pressure and wet circumstances. Further, the top cover has good strength characteristics and once capital expenditures are made, is easy to fabricate and handle because of the relatively low weight. With regard to manufacturing and assembly, a major advantage is that there will be no need to go through a complicated welding, machining and painting operation. Furthermore, since the panels are molded, it is easy to include the rain barrier berms for directing the rain out of the way of the access doors in the front and rear walls.
- The specification describes in detail an embodiment of the present invention. Other modifications and variations will, under the doctrine of equivalents, come within the scope of the appended claims. For example, different dimensions and geometries or different materials are considered equivalent structures. Still other alternatives will also be equivalent as will many new technologies. There is no desire or intention here to limit in any way the doctrine of equivalents.
