Abstract

The present invention provides for a low cost, light weight, high strength earthquake certified power and equipment enclosure module which provides for an effective housing of DC batteries allowing for simultaneous dual voltage functionality with intelligent evacuation of thermal and toxic residuals. Stacking and interlocking the modules provides an environment for housing diverse electrical components making the invention enclosure invulnerable to obsolescence. Intuitive disassembly and reassembly allows the cabinet modules to be moved easily too hard-to-reach locations eliminating the need for costly cranes, lifts or excessive man-power. The design delivers the smallest footprint with the highest power density, embedded alarming and thermal management ensures safety in operation.

Claims

1. A modular enclosure for housing electronic devices and power banks at a telecommunications site, said enclosure comprising a plurality of cabinet modules (000) characterized in having integrated means for allowing:

stacking to provide increasingly large storage capacity within a diminutive footprint;

provision of user-selectable backup power output among +24V and/or −

48V in single voltage, simultaneous dual voltage and single voltage per shelf configurations;

ambient air-assisted integrated active management of the thermal profile of said modular enclosure;

ambient air-assisted passive management of the emission profile of said modular enclosure; and

detection and generation of alarm upon fault in the electrical I/O, the means for thermal and emissions management and in event of intrusion into any module (000) comprising said enclosure for housing electronic devices and power banks at a telecommunications site.

2. The modular enclosure of claim 1, wherein the stackable cabinet modules (000) each further comprise at least one top panel (010), a bottom panel (011), an outward opening front hatch (001) and three peripheral wall panels which together enclose a hollow external shell (009) within which a high-strength steel chassis (004) may be received for:

defining compartments sized according to the electronic devices and power banks to be housed; and

enclosing running void spaces adjoining inner walls of the external shell for ambient air-assisted thermal management of the modular enclosure (000)

3. The modular enclosure of claim 2, wherein the top panel (010) of each stackable cabinet (000) has outward surface artifacts mated for docking with bottom panel (011) of overhead cabinet module to assume a vertically stacked configuration.

4. The modular enclosure of claim 2, wherein the coupling between mated top (010) and bottom (011) panels of stacked cabinet modules is secured by means chosen among nut-bolts, threaded rivets, riv-nuts, their equivalents and their combinations.

5. The modular enclosure of claim 2, wherein the peripheral wall panels and hatch (001) have perforations for ventilation leading from the running void spaces between inner walls of the external shell (009) and chassis (004) to allow dissipation of internal heat buildup to the surroundings.

6. The enclosure according to claim 1, wherein the integrated means for managing thermal profile of said modular enclosure comprise interdependent operation of:

an exhaust fan affixed operatively to the hatch (001) of each stackable cabinet module which, when operated upon buildup of heat beyond a predefined limit, causes a draft of cool air to flow within the running void spaces between inner walls of the external shell (009) and chassis (004) of the cabinet module (000) thereby acting as a heat sink for dissipation of the excess heat within said modular enclosure;

a custom-fitted heating pad juxtaposed within the lumen of module (000) which, when operated upon lowering of temperature beyond a predefined limit, causes buildup of heat to acceptable levels in the cabinet module (000)

Wherein the limits of temperature for actuating the fan and/or the heating pad are user-selectable and triggered in response to logging of temperature data by thermal sensors communicatively dispersed among each cabinet module (000).

7. The enclosure according to claim 6, wherein heating and cooling functions are complementary due to the airflow being utilized reversibly as a heat and/or cold sink and further establish synergy in management of emissions by maintaining a positive pressure in the cabinet module (000).

8. The enclosure according to claim 1, wherein provision of user-selectable backup power output is enabled by implementing:

among+24V and/or −

48V in single voltage, simultaneous dual voltage and single voltage per shelf configurations is enabled by connections;

in case of same+24V OR −

48V (same voltage) for both shelves of a single cabinet module 000 wherein the routing and return of DC power cable and configuration of bus bar connections are implemented as illustrated in FIGS. 11(a to c);

in case of +24V for one shelf AND −

48V for the other shelve of a single cabinet module 000 as required by the user, wherein the routing and return of DC power cable and configuration of bus bar connections are implemented as illustrated in FIGS. 12(a to c);

+24V or −

48V on either shelf of cabinet module 000, and another or more cabinet modules, that mirror the first module and when stacked, add up to the power requirements of the user in a step-wise manner, wherein the routing and return of DC power cable and configuration of bus bar connections are implemented as illustrated in FIG. 13(a) for double stack and 14 (a and b) for triple stack columns; and

+24V on both shelves of a single cabinet module 000 and −

48V for both shelves of another cabinet module stacked above, or visa-versa, and another module above that mirrors either of the cabinets below to support the power requirement for the user, wherein the routing and return of DC power cable and configuration of bus bar connections are implemented as illustrated in FIGS. 13(b) and 14(c and d)

9. The enclosure according to claim 1, wherein each of the components comprising the cabinet module (000) are formed independently and assembled before installation on site.

10. The enclosure according to claim 1, wherein:

the means for detection and generation of alarm upon fault in electrical I/O is an electrical fuse;

the means for thermal and emissions management and event of intrusion are an electrical fuse, thermal sensor and electrical circuit

11. The enclosure according to claim 6, wherein the flow-through ventilation panels are left in place to prevent the air from passing between cabinet enclosures thereby isolating the thermal dynamics of each cabinet to itself thus resulting in an isolative cabinet-specific method of thermal and/or emissions management.

12. The enclosure according to claim 6, wherein the flow-through ventilation panels are removed to allow air to pass freely between the stacked cabinets thereby ventilating the adjacent cabinet stack and resulting in an integrative method of thermal and/or emissions management.
