Embodiment Construction

[0028] In the figures, the same or similar elements are indicated by the same reference numerals. The drawings are merely schematic representations, not intended to portray specific parameters of the invention. Additionally, the drawings are intended to depict only typical embodiments of this invention and therefore should not be considered as limiting the scope of the invention.

[0029] Figure 1aA first perspective view of an embodiment of a cooling circuit 90 comprising the internal combustion engine 10 , the EGR cooler 40 and the retarder cooler 30 is shown. Exhaust gas from the internal combustion engine 10 may be routed to an exhaust gas recirculation system (EGR system), where an EGR cooler 40 cools exhaust gas discharged from the internal combustion engine 10 . The internal combustion engine 10 is coupled to a retarder 32 for braking the vehicle, wherein the retarder is cooled by a retarder cooler 30 .

Abstract

The invention relates to a cooling circuit (90) for a vehicle (100), particularly a commercial vehicle, wherein the cooling circuit (90) comprises a combustion engine (10), a retarder cooler (30) for cooling a retarder (32), an EGR cooler (40) for cooling an exhaust gas of the combustion engine (10), and a coolant cooler (20) which is coupled to the combustion engine (10) for cooling the combustion engine (10) by means of a coolant. The retarder cooler (30) is arranged permanently in series with the EGR cooler (40) in a fluid path (60) of the coolant forming a return line for the coolant from the combustion engine (10) to the coolant cooler (20).

Description

technical field [0001] The invention relates to a cooling circuit for a vehicle, in particular a commercial vehicle, wherein the cooling circuit comprises an internal combustion engine, a retarder cooler for cooling the retarder, an EGR cooler for cooling the exhaust gas of the internal combustion engine and a cooling circuit coupled to the internal combustion engine To cool the coolant cooler of the internal combustion engine with the coolant. The invention further relates to a vehicle, such as a truck, comprising a cooling circuit. Background technique [0002] The limited space available within the internal combustion engine compartment of a vehicle is well known in the art. Especially for commercial vehicles, such as light, medium or heavy vehicles, space is limited due to space constraints in the vehicle cabin, where the internal combustion engine is crowded between the cooler housing and the front axle. Due to the enhanced discharge strategy, larger coolers are requi...
