Embodiment Construction

[0021] According to the invention, the cooling device comprises a low temperature circuit for cooling the charge air of an internal combustion engine, in particular a turbocharger of a diesel engine, and an engine cooling circuit for cooling the internal combustion engine, wherein the charge air cooling is arranged in the low temperature circuit The device can be fluidly connected to the low-temperature circuit or the engine cooling circuit on the coolant inlet side via the first valve arrangement and on the coolant outlet side via the second valve arrangement in a fluidic heat transfer manner.

[0022] Thus, the charge air cooler can pass through the The first and second valve means are directly integrated in the engine cooling circuit. Thus, on the one hand, the energy present in the engine cooling circuit can be used in an energy-efficient manner to heat the charge air. On the other hand, the engine cooling circuit in which the charge air cooler is integrated is only loade...

Abstract

Embodiments for a cooling arrangement are provided. In one example, a cooling arrangement comprises a low-temperature circuit for charge-air cooling of a turbocharger of an internal combustion engine, an engine cooling circuit for cooling the internal combustion engine, and a charge-air cooler arranged in the low-temperature circuit and connected in a fluid-conducting manner on a coolant inlet side, via a first valve device, to the low-temperature circuit and to the engine cooling circuit, and on a coolant outlet side, via a second valve device, to the low-temperature circuit and to the engine cooling circuit. In this way, coolant from the engine may heat the charge-air cooler under certain conditions.

Description

[0001] related application [0002] This application claims priority from German Patent Application No. 102011076457.7 filed May 25, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a cooling device for a superchargeable internal combustion engine. Background technique [0004] The cooling device is used, for example, in an internal combustion engine with a turbocharger, in particular a motor vehicle engine, in order to cool the internal combustion engine by means of an engine cooling circuit and to feed the supercharging to the internal combustion engine by means of a low-temperature cooling circuit via the turbocharger Air. [0005] Modern superchargeable internal combustion engines, in particular superchargeable diesel engines, usually have a charge air cooling system by means of which the air required for supercharging the internal combustion engine is cooled. In this case, a charge air cooling s...
