Abstract

In accordance with presently disclosed embodiments, an uninterruptable power supply (UPS) is provided. The UPS utilizes two chambers, one which is pneumatically sealed to house control electronics, and one that is not sealed that houses transformers. The pneumatically sealed compartment is cooled through a heat exchanger or air conditioner as well as through a heat sink. The chamber which houses the transformers is cooled by a fan which circulates air from outside the chamber through the chamber and out vents in a wall of the chamber. The UPS may utilizes a series of ducts to direct air flow into the chamber housing the transformers in such a way that the air enters the bottom of the chamber past the control electronics and through vents near the front of the chamber. The UPS may utilize a series of ducts to direct air flow past the heat sink attached to the pneumatically sealed chamber.

Claims

1. An uninterruptable power supply (UPS) comprising:

a heat exchange compartment comprising a heat exchanger;

a first chamber that is pneumatically isolated from an environment outside of the UPS, wherein the first chamber houses control electronics and a first portion of a heat sink, wherein the first chamber is in fluid communication with the heat exchange compartment via a first wall of the first chamber so as to cool the first chamber, and wherein the heat sink is coupled to the control electronics and a second wall of the first chamber so as to cool the control electronics; and

a second chamber housing one or more transformers, said second chamber is in fluid communication with a first fan via a first wall of the second chamber, wherein one or more other walls of the second chamber comprise vents to facilitate circulation of a first flow of air blown by the first fan through the second chamber.

2. The UPS of claim 1 wherein the UPS comprises a housing and wherein the housing comprises stainless or painted steel and wherein the housing is waterproof.

3. The UPS of claim 1 wherein the heat exchange compartment further comprises a heater.

4. The UPS of claim 1 wherein the UPS further comprises a duct coupled with a second portion of the heat sink, and a second fan in fluid communication with the duct, such that the second fan circulates a second flow of the air through the duct and removes heat from the second portion of the heat sink.

5. The UPS of claim 1 wherein the UPS further comprises a touch screen or an HMI Screen located on an exterior surface of the UPS, wherein the touch screen or the HMI Screen allows an operator to control multiple UPS'"'"'s in a facility, the UPS being one of the multiple UPS'"'"'s.

6. The UPS of claim 1 wherein the UPS further comprises a set of lights on an exterior of the UPS that indicate a status and an operation of the UPS.

7. The UPS of claim 1 wherein the UPS comprises double inputs for utility lines.

8. The UPS of claim 1 wherein the UPS comprises an Input/Output box on an exterior surface, the Input/Output box comprises inputs for utilities.

9. A method of cooling an uninterruptable power supply (UPS) comprising:

housing a heat exchanger or an air conditioner in a heat exchange compartment;

housing control electronics and a first portion of a heat sink in a first chamber wherein the first chamber is pneumatically isolated from an environment outside of the UPS;

placing the first chamber in fluid communication with the heat exchanger or the air conditioner;

housing one or more transformers in a second chamber;

placing the second chamber adjacent to the first chamber;

circulating a first flow of outside air though the second chamber using a first fan, and a vent located on a wall of the second chamber;

cooling the first chamber via the heat sink; and

cooling the first chamber via the heat exchanger or the air conditioner.

10. The method of claim 9 further comprising placing the UPS in a housing comprised of stainless or painted steel wherein the housing is waterproof.

11. The method of claim 9 further comprising:

attaching a first duct to a second portion of the heat sink wherein the duct has an intake and an exhaust;

attaching the first duct to the first chamber;

placing a second fan in fluid communication with the first duct; and

circulating a second flow of the outside air through the duct so as to remove heat from the heat sink.

12. The method of claim 9 further comprising housing a heater in the heat exchanger compartment.

13. The method of claim 9 further comprising placing a touch screen or an HMI Screen located on an exterior surface of the UPS, wherein the touch screen or the HMI Screen allows an operator to control multiple UPS'"'"'s in a facility, the UPS being one of the multiple UPS'"'"'s.

14. The method of claim 9 further comprising placing a set of lights on an exterior of the UPS that indicate a status and an operation of the UPS.

15. An uninterruptable power supply (UPS) comprising:

a heat exchange compartment comprising a heat exchanger;

a first chamber that is pneumatically isolated from an environment outside of the UPS, wherein the first chamber houses control electronics and a first portion of a heat sink, wherein the first chamber is in fluid communication with the heat exchange compartment via a first wall of the first chamber so as to cool the first chamber, and wherein the heat sink is configured to cool the control electronics; and

a second chamber housing one or more transformers wherein said second chamber is in fluid communication with a first fan via a first wall of the second chamber, wherein one or more other walls of the second chamber comprise vents to facilitate circulation of a first flow of outside air;

a second fan within the second chamber wherein the second fan circulates the first flow of the air through the second chamber past the transformers so as to cool the transformers and out the vents in the one or more other walls of the second chamber;

a first duct comprising a first air intake and a first exhaust wherein the first duct is attached to a top and a back of the first chamber and wherein the duct is coupled to a second portion of the heat sink;

a third fan in fluid communication with the first duct so as to cool the heat sink by circulating a second flow of the outside air through the duct wherein the second flow of the air travels through the first intake, over the second portion of the heat sink, and through the first exhaust; and

a second duct comprising a second air intake wherein the second duct is attached to the second chamber wherein the second duct is attached to a top and a back of the second chamber and wherein the second duct is in fluid communication with the second chamber;

wherein the first fan and the second fan are in fluid communication with the second duct so as to cool the second chamber by circulating the first flow of the outside air through the second air intake into the second duct, and into the second chamber.

16. The UPS of claim 15 wherein the UPS comprises a housing wherein the housing comprises stainless or painted steel and is waterproof.

17. The UPS of claim 15 wherein the UPS further comprises a touch screen or an HMI Screen located on an exterior surface of the UPS, wherein the touch screen or the HMI Screen allows an operator to control multiple UPS'"'"'s in a facility, the UPS being one of the multiple UPS'"'"'s.

18. The UPS of claim 15 wherein the heat exchange compartment further comprises a heater.

19. The UPS of claim 15 wherein the UPS further comprises a set of lights on an exterior of the UPS that indicate a status and an operation of the UPS.

20. The UPS of claim 15 wherein the UPS comprises an Input/Output box on an exterior surface, the Input/Output box comprises inputs for utilities.
