Abstract
A cooling apparatus cools a battery and a DC/DC converter. In a duct, a battery cooling fan having a great rated capacity is installed. The duct branches into a battery-side intake duct and a DC/DC converter-side intake duct on the downstream side of the battery cooling fan. In the battery-side intake duct, the battery is installed to received cooling air. In the DC/DC converter side intake duct, the DC/DC converter is installed to receive cooling air. A DC/DC converter cooling fan having a small rated capacity is installed directly upstream of the DC/DC converter. An ECU controls the two cooling fans based on the temperature of the battery and the DC/DC converter.
Claims15
An in-vehicle device cooling apparatus cooling a power storage mechanism and an electric device that are incorporated in a vehicle, comprising:
- a first supply passage supplying a medium that cools said power storage mechanism to said power storage mechanism;
- and
- a second supply passage supplying a medium that cools said electric device to said electric device, wherein
- one of said first and second supply passages branches from the other at a branching portion on upstream side of said power storage mechanism and said electric device, said cooling apparatus further comprising
- an adjustment mechanism adjusting a flow rate of the medium supplied to said first supply passage and a flow rate of the medium supplied to said second supply passage, in accordance with a cooling request of said power storage mechanism and a cooling request of said electric device, wherein
- said adjustment mechanism includes
- a medium supply mechanism that is installed upstream from said branching portion and that supplies the medium, and
- a medium adjustment mechanism that is installed in said second supply passage downstream from said branching portion and that adjusts the flow rate of the medium supplied to said second supply passage.
An in-vehicle device cooling apparatus cooling a power storage mechanism and an electric device that are incorporated in a vehicle, comprising:
- a first supply passage supplying a medium that cools said power storage mechanism to said power storage mechanism;
- and
- a second supply passage supplying a medium that cools said electric device to said electric device, wherein
- one of said first and second supply passages merges into the other at a merging portion on downstream side of said power storage mechanism and said electric device, said cooling apparatus further comprising
- an adjustment mechanism adjusting a flow rate of the medium supplied to said first supply passage and a flow rate of the medium supplied to said second supply passage, in accordance with a cooling request of said power storage mechanism and a cooling request of said electric device, wherein
- said adjustment mechanism includes
- a medium supply mechanism that is installed downstream from said merging portion and that supplies the medium, and
- a medium adjustment mechanism that is installed in said second supply passage upstream from said merging portion and that adjusts the flow rate of the medium supplied to said second supply passage.
