Vehicle battery charger having cooling blower providing improved cooling efficiency
First Claim
1. A charger for a vehicle, comprising a power source unit and a feeding coupler connected to said power source unit via a cable and adapted to be coupled to a receiver of a vehicle, said power source unit comprising:
- an outer casing having a top, a bottom with an intake hole and an exhaust hole;
a duct having a vertically extending passage disposed in said outer casing, said passage having an upper opening and a lower opening, said duct enclosed by said outer casing; and
a cooling blower disposed in said outer casing above said duct so that said blower causes a flow of air in which air is taken into said casing from said intake hole, enters said passage of said duct via said upper opening, flows down in said passage, and flows out of said outer casing via said lower opening and said exhaust hole.

Abstract
An electromagnetic induction non-contact charger includes a stand and a power source device arranged on the stand. A feeding coupler is coupled to a cable extending from the power source device. The power source device includes an outer casing and a vertical duct arranged in the outer casing. An intake hole and an exhaust hole are provided at the bottom of the outer housing, and a blower is arranged in the outer casing above the duct, so that air is taken in from the intake hole, flows up in the outer casing and outside the duct, enters the duct via blower at the top of the duct, flows down in the duct, and is discharged from the exhaust hole. The duct is constructed using a cooling fin plate, and a circuit board is directly attached to the duct. The stand is tubular, and the exhaust hole is in communication with interior space of the stand. The stand has outlet holes and louvers which are attached to the stand.

9. A charger for a vehicle, comprising a power source unit, a feeding coupler connected to said power source unit via a cable and adapted to be coupled to a receiver of a vehicle, and a stand supporting the power source unit;
-
said power source unit comprising;
an outer casing having a top, a bottom with an intake hole and an exhaust hole;
a duct having a vertically extending passage disposed in said outer casing, said passage having an upper opening and a lower opening, said duct enclosed by said outer casing;
a cooling blower disposed in said outer casing above said duct so that said blower causes a flow of air in which air is taken into said casing from said intake hole, enters said passage of said duct via said upper opening, flows down in said passage, and flows out of said outer casing via said lower opening and said exhaust hole;
said stand comprising a tubular body having an internal space and outlet holes formed through said tubular body, said power source unit being fixed to said stand with said exhaust hole in communication with said internal space; and
louvers formed separately from and attached to said tubular body so that said louvers substantially cover said outlet holes, as viewed in a direction perpendicular to an outer surface of said tubular body, and an extending length of said louver measured from said tubular body in said direction is longer than that of a louver which is formed by a drawing process. - View Dependent Claims (10)

11. A charger for a vehicle, comprising a power source unit and a feeding coupler connected to said power source unit via a cable and adapted to be coupled to a receiver of a vehicle, said power source unit being of a wall mounted type and comprising:
-
an outer casing having a top, a bottom with an intake hole and an exhaust hole;
a duct having a vertically extending passage disposed in said outer casing, said passage having an upper opening and a lower opening, said duct enclosed by said outer casing;
a cooling blower disposed in said outer casing above said duct so that said blower causes a flow of air in which air is taken into said casing from said intake hole, enters said passage of said duct via said upper opening, flows down in said passage, and flows out of said outer casing via said lower opening and said exhaust hole; and
a partition member disposed below said outer casing for separating a region including said exhaust hole from a region including said intake hole.
