Abstract

An inverter is provided. In the inverter, an electronic device is disposed inside a first enclosure; a heat radiator and a cooling fan are disposed inside a second enclosure; a magnetic element is disposed outside the first enclosure and the second enclosure. In this way, the cooling effect on the electronic device inside the first enclosure and the heat radiator inside the second enclosure are increased as they may be less affected by the heat generated by the magnetic element. It is also beneficial to heat dissipation of the magnetic element. The cooling fan blows the heat radiator for heat dissipation; the magnetic element does not block the relatively cold air flowing through the heat radiator. Therefore, a less obstructed air duct is formed, and the dissipation effect is improved.

Claims

1. An inverter comprising:

an electronic device, a magnetic element, a heat radiator, a cooling fan, a first enclosure and a second enclosure connected with the first enclosure via a mounting plate, wherein

the mounting plate is located between the first enclosure and the second enclosure;

the electronic device is disposed inside the first enclosure;

the heat radiator and the cooling fan are disposed inside the second enclosure;

the magnetic element is disposed outside the first enclosure and the second enclosure;

the magnetic element is disposed on a top plate of the second enclosure;

the cooling fan is disposed on a side plate of the second enclosure inside the second enclosure, the side plate being perpendicular to gaps between fins of the heat radiator; and

the side plate is perpendicular the top plate.

2. The inverter according to claim 1, wherein the first enclosure and the second enclosure share one mounting plate, and are located on two parallel mounting surfaces of the mounting plate respectively.

3. The inverter according to claim 1, wherein the heat radiator is disposed on the mounting plate inside the second enclosure;

and the electronic device is disposed on the mounting plate inside the first enclosure.

4. The inverter according to claim 1, wherein one or more vents are disposed in another side plate of the second enclosure, the another side plate being perpendicular to the gaps between the fins of the heat radiator.

5. The inverter according to claim 4, wherein the number of the vents is more than one, and the vents are uniformly disposed at positions corresponding to the gaps between the fins of the heat radiator.

6. The inverter according to claim 1, wherein the number of the cooling fans is four.
