Abstract

An apparatus and a method for providing adequate cooling inside control box of an electrical equipment. A method includes receiving air from one or more air ducts in a first section wherein the first section is coupled with the one or more air ducts. The method also includes providing the air to a first fan associated with the first section and transferring the air by the first fan to one or more second fans. The method further includes receiving air from the one or more air ducts associated with the first section to one or more vents in the second section and transferring the air from one or more vents to the one or more louvers and the first fan. Air transferred to the one or more louvers and the first fan is further transferred to the one or more second fans.

First claim

What is claimed is:

1. An outdoor unit comprising:
a first section and a second section;
the first section coupled with one or more air ducts to provide air to a first fan associated with the first section, wherein the first fan transfers the air to one or more second fans, the one or more air ducts, the first fan and the one or more second fans defining a first airflow path;
the second section comprising one or more vents and one or more louvers, the one or more vents configured to receive air from the one or more air ducts associated with the first section, wherein the air through the one or more vents is transferred to the one or more louvers and to the one or more second fans along a second airflow path, wherein the air through the one or more vents is transferred to the first fan and is further transferred to the one or more second fans along a third airflow path.

2. The outdoor unit of claim 1 , wherein the first section corresponds to a heat sink and the second section corresponds to electronic components of the outdoor unit.

3. The outdoor unit of claim 1 , wherein the first section and the second section are encapsulated inside a box of the outdoor unit.

4. The outdoor unit of claim 1 , wherein the one or more air ducts receive an ambient air from the environment.

5. The outdoor unit of claim 1 , wherein the one or more vents in the second section comprise four vents.

6. The outdoor unit of claim 1 , wherein the one or more louvers are present on two sides of the second section.

7. The outdoor unit of claim 1 , wherein the second section is covered by a cover plate.

8. The outdoor unit of claim 1 , wherein the one or more air ducts are present at the lower end of the outdoor unit.

9. The outdoor unit of claim 1 , wherein the one or more second fans are associated with a third section of the outdoor unit.

10. The outdoor unit of claim 9 , wherein the third section corresponds to an outdoor section for expelling out the air received from the first section and the second section.

11. The outdoor unit of claim 10 , wherein the expelling the air from the third section lowers temperature inside the first section and the second section of the outdoor unit.

12. A method comprising:
receiving air from one or more air ducts in a first section, the first section coupled with the one or more air ducts;
along a first airflow path, providing the air to a first fan associated with the first section and transferring the air by the first fan to one or more second fans;
receiving the air from the one or more air ducts associated with the first section to one or more vents in a second section;
along a second airflow path, providing the air through the one or more vents to the one or more louvers and then to the one or more second fans; and
along a third airflow path, providing air through the one or more vents to the first fan and then to the one or more second fans.

13. The method of claim 12 , wherein the air duct receives an ambient air from the environment.

14. The method of claim 12 , wherein the one or more vents in the second section comprise four vents.

15. The method of claim 12 , wherein the one or more louvers are present on two sides of the second section.

16. The method of claim 12 , wherein the first section corresponds to a heat sink and the second section corresponds to electronic components of an outdoor unit.

17. The method of claim 16 , wherein the one or more second fans are associated with a third section of the outdoor unit.

18. The method of claim 17 , wherein the third section corresponds to an outdoor section for expelling out the air received from the first section and the second section.

19. The method of claim 18 , wherein the expelling the air from the third section lowers temperature inside the first section and the second section of the outdoor unit.

20. The method of claim 19 , wherein the first section and the second section are encapsulated inside a box of the outdoor unit.
