Heat sink
A charger for an electrical device (e.g., a site light) includes a housing defining an interior cavity, and one or more openings formed in the housing. A heat sink is disposed in the interior cavity of the housing and is operable to dissipate heat produced in the housing. The heat sink is positioned in a facing relationship with the one or more openings such that the heat sink is at least partially exposed to the exterior. The heat sink is in heat transfer relationship with component of charger electronics of the charger.
1. A charger for an electrical device, the charger comprising:
a housing defining an interior cavity;
one or more openings formed in the housing; and
a heat sink disposed in the interior cavity of the housing and operable to dissipate heat produced in the housing, the heat sink positioned in a facing relationship with the one or more openings such that the heat sink is at least partially exposed to an exterior, the heat sink in heat transfer relationship with components of charger electronics of the charger, the heat sink including a fin portion having one or more fins extending to the one or more openings, at least one fin including a flange extending therefrom, the flange engaging the housing at an interface.
2. The charger of claim 1 , wherein the housing includes a longitudinal axis extending therethrough, and wherein the one or more openings extends along parallel with or perpendicular to the longitudinal axis.
3. The charger of claim 2 , wherein each of the one or more openings has a width relative to the longitudinal axis, and wherein each width is different.
4. The charger of claim 1 , wherein the heat sink defines a heat sink interior cavity in fluid communication with the exterior of the housing, and a seal is disposed at the interface between the flange and the housing separating the heat sink interior cavity and the interior cavity of the housing.
5. The charger of claim 1 , further comprising a printed circuit board having the charger electronics and positioned within the interior cavity, the heat sink coupled to the printed circuit board.
6. The charger of claim 1 , wherein the housing includes a plurality of walls forming the interior cavity, wherein the plurality of walls defines a plurality of sides and an end connecting the plurality of sides of the housing, and wherein the one or more openings is positioned on one of one of the plurality of sides and the end of the housing.
7. A site light comprising:
a main housing having a plurality of inner surfaces defining a first cavity;
a charger supported in the main housing and positioned within the first cavity, the charger including
a charger housing defining a charger interior cavity;
one or more openings formed in the charger housing; and
a heat sink disposed in the interior cavity of the charger housing and operable to dissipate heat produced in the charger housing, the heat sink positioned in a facing relationship with the one or more openings such that the heat sink is at least partially exposed to an exterior, the heat sink in heat transfer relationship with components of charger electronics of the charger, the heat sink including a fin portion having one or more fins that extend to the one or more openings, wherein at least one fin includes a flange extending from the fin, the flange engaging the charger housing at an interface; and
a fan supported by the charger housing, wherein the fan is positioned exterior to the charger housing, and wherein the fan is operable to pass air over the one or more openings.
8. The site light of claim 7 , wherein the charger housing includes a longitudinal axis extending therethrough, and wherein the one or more openings extends along parallel with or perpendicular to the longitudinal axis.
9. The site light of claim 8 , wherein each of the one or more openings has a width relative to the longitudinal axis, and wherein each width is different.
10. The site light of claim 7 , wherein a seal is disposed at the interface between the flange and the charger housing separating the first cavity of the main housing and the charger interior cavity.
11. The site light of claim 7 , further comprising a printed circuit board having the charger electronics and positioned within the charger housing, the heat sink coupled to the printed circuit board.
12. The site light of claim 7 , wherein the fan has a rotational axis that extends parallel with a longitudinal axis of the one or more openings.
13. A site light comprising:
a main housing having a plurality of inner surfaces defining a first cavity; and
a charger supported in the main housing and positioned within the first cavity, the charger including
a charger housing defining a charger interior cavity;
one or more openings formed in the charger housing; and
a heat sink disposed in the charger interior cavity of the charger housing and operable to dissipate heat produced in the charger housing, the heat sink positioned in a facing relationship with the one or more openings such that the heat sink is at least partially exposed to an exterior, the heat sink in heat transfer relationship with components of charger electronics of the charger, the heat sink having one or fins and at least one fin includes a flange extending from the fin, the flange engaging the charger housing at an interface, and a seal is disposed between the flange and the charger housing.
