Abstract
A battery cooling apparatus for positively cooling an in-vehicle battery is disclosed. Air that has passed through a cooler (5) is supplied to batteries (1), and only internal air, but not external air, passes through the cooler (5). In this way, the batteries (1) can be cooled without being greatly affected by the disturbances such as the heat of an exhaust pipe and sunlight. Thus, the batteries (1) can be sufficiently cooled without increasing the heat radiation area, i.e. the surface area of the batteries (1). Noise of cooling air flow can be reduced while at the same time suppressing increases in both size and production cost of the battery.
Claims4
A battery cooling apparatus for cooling at least a battery mounted on an automotive vehicle, comprising:
- blowing means having an internal air blowing mode for sucking air from an inside of a compartment of the vehicle and blowing the air to said at least a battery, and an external air blowing mode for sucking air from an outside of the compartment and blowing the air to said at least a battery;
- and
- a cooling means for cooling the air blown to said at least a battery only in said internal air blowing mode.
A battery cooling apparatus for cooling at least a battery mounted on an automotive vehicle, comprising:
- a blower for blowing air to said at least a battery;
- an internal/external air switching unit arranged on an inlet side of said blower for controlling flow rate of the air, from an inside of a compartment of the vehicle, supplied to the blower and flow rate of the air, from an outside of the compartment, supplied to the blower;
- and
- a cooling means arranged in an air path leading from an internal air inlet of said internal/external air switching unit to the inlet side of said blower for cooling the air.
