An apparatus and method of controlling heat of an engine compartment when stopped are provided. The apparatus and method of controlling heat of an engine compartment improve fuel efficiency by managing heat of the engine compartment when a vehicle is stopped after driving.

A device for sequentially switching at least one first and at least one second Venetian blind, the slats of which can each be synchronously rotationally moved by means of at least one coupling rod in order to open and close the blinds. The device includes an actuator for generating a rotational movement of the slats through 80° to 90°, a coupling for rotatably coupling the actuator to a slat of the first blind, a link rod which has a partially-circular link, and a transmission rod. The actuator has an eccentric pin parallel to its axis of rotation which engages in the partially-circular link of the link rod, and the linear movement of the link rod is transmitted to the coupling rod of the at least second blind.

The present disclosure relates to an active air flap apparatus for a vehicle coupled to an air inlet of a grill to cool the inside of an engine room when a vehicle travels, and the active air flap apparatus for a vehicle includes a frame coupled to a rear surface of the grill in which the air inlet is formed, a plurality of flap portions coupled to an inside of the frame to open or close the air inlet and arranged in a vertical direction of the frame, an actuator coupled to an outside of the frame to generate power, a gear unit operated by the power generated from the actuator, and a connection unit connecting the flap portions and the gear unit to each other to operate the flap portions according to the operation of the gear unit.

A method of cooling an aircraft power plant having a combustion engine is disclosed. The method comprises in a first operating mode, inducing a cooling air flow through a heat exchanger in an air conduit via a flow inducing device fluidly connected to the air conduit, the heat exchanger connected in heat exchange relationship with the power plant of the aircraft. The method comprises, in a second operating mode, bypassing the cooling air flow from the flow inducing device via a selectively closable air outlet of the air conduit downstream of the heat exchanger. A cooling system for an aircraft power plant is also disclosed.

A cooling system is provided to cool an engine of a vehicle, which includes a cooling water passage through which cooling water is supplied to a water jacket formed in the engine, and having an undercover cooling water passage provided in an undercover, a radiator provided in the cooling water passage and configured to cool the cooling water by exchanging heat with air flowing into an engine bay from a grille, a flow rate adjuster configured to adjust a cooling water flow rate supplied to the undercover cooling water passage, and a controller configured to acquire a temperature of the cooling water of the water jacket in the engine and, when the temperature is above a temperature threshold, control the flow rate adjuster to increase the flow rate of the cooling water supplied to the undercover cooling water passage compared to when the acquired temperature is below the temperature threshold.

A cooling system configured to cool an engine of a vehicle is provided, which includes a cooling water passage through which cooling water is supplied to a water jacket in the engine, and having an undercover cooling water passage provided in an undercover and where the cooling water is cooled by exchanging heat with air below the undercover, a radiator provided in the cooling water passage and configured to cool the cooling water by exchanging heat with air flowing into an engine bay from a grille, a flow rate adjuster, a grille shutter provided to the grille and configured to change an effective opening area of the grille, and a controller configured to determine abnormality of the grille shutter and control, when determined as abnormal, the flow rate adjuster to increase the flow rate of the cooling water supplied to the undercover cooling water passage.

The invention relates to a cooling module (22) for a motor vehicle (10) with an electric motor (12), comprising: —at least one heat exchanger (30.sub.1-30.sub.4); —at least one tangential-flow turbomachine (28) capable of creating an air flow that comes into contact with the plurality of heat exchangers (30.sub.1-30.sub.4); —a plurality of flaps (36P, 36A) movable between a first position, referred to as the position opening the cooling module (22), and a second position, referred to as the position closing the cooling module (22), said plurality of flaps (36P, 36A) occupying a portion of the cooling module not occupied by said at least one tangential-flow turbomachine (28).

In an engine compartment, a separation wall is provided between an intake pipe, which runs around to a rear side of the engine from a lateral side of the engine, and the engine. On an outer side of this separation wall, a travel wind guide having a vertical wall portion that opposes the separation wall with the intake pipe being therebetween is provided. The travel wind guide guides vehicle travel wind that is introduced into the engine compartment in a manner to cause the vehicle travel wind to flow along the intake pipe on the outer side of the separation wall.
