Cooling structure and cooling control system
A cooling structure for an electronic control unit which is mounted in a vehicle, includes: a duct having a flow channel on which the electronic control unit is disposed; and a blower configured to take air in the inside of the vehicle and to emit the air to the flow channel of the duct, wherein the duct is configured to: cool the electronic control unit with the air emitted from the blower; and discharge air which has been used to cool the electronic control unit to the outside of the vehicle.
1. A cooling structure for at least two electronic control units mounted in a vehicle, comprising:
a duct including a flow channel on which the at least two electronic control units are disposed; and
a blower configured to take air in the inside of the vehicle and to emit the air to the flow channel of the duct,
wherein the duct is configured to:
cool the at least two electronic control units with the air emitted from the blower; and
discharge air which has been used to cool the at least two electronic control units to the outside of the vehicle,
wherein the at least two electronic control units are arranged from upstream to downstream on the flow channel of the duct in increasing order of a heat-resistant temperature,
wherein the duct includes a first opening and a second opening, the first opening being sealed with a surface of a first housing of a first electronic control unit including a first heat sink, the second opening being sealed with a surface of a second housing of a second electronic control unit including a second heat sink, and the first opening being arranged downstream on the flow channel of the duct from the second opening
wherein the at least two electronic control units include the first electronic control unit and the second electronic control unit, and
wherein the first electronic control unit has a higher heat-resistant temperature than the second electronic control unit.
2. The cooling structure according to claim 1 , wherein the duct branches into a first exhaust channel connected the outside of the vehicle and a second exhaust channel connected in the inside of the vehicle.
3. The cooling structure according to claim 1 , wherein the first electronic control and the second electronic control unit are spaced apart from each other.
4. The cooling structure according to claim 1 , further comprising:
an air conditioner connected to the flow channel in parallel with the blower, the blower blowing the air from inside the vehicle into a first intake channel of the flow channel, and the air conditioner blowing cooled air into a second intake channel of the flow channel.
