Embodiment Construction

[0023] figure 1 Shows the state of the art in this field, and shows a simple example of a vehicle-based cooling system 1 using common "passive" cooling, whereby the coolant, usually in the form of a water and glycol mixture, is for example passed through a mechanical The drive pump 3 pumps around in the substantially closed cooling circuit 2 . The coolant passes through one or more components 4-6 in the vehicle that require cooling. These components may be the vehicle's engine, engine control components, EGR cooler, intercooler, and the like. The coolant flows through the air-cooled low-temperature radiator 7 before being led back to the pump 3 . The cooling effect of the radiator 7 is particularly limited by the temperature of the ambient air and the airflow velocity passing through the radiator 7, and for example, when the vehicle travels in a high-temperature region, the cooling effect of the radiator 7 will be significantly reduced. This means that adequate cooling is n...

Abstract

The invention relates to a method for cooling of coolant in a vehicle comprising a refrigerant circuit (9) driven by a compressor (10), and with a condenser (11), an evaporator (12) and a radiator (7). The invention is achieved by connecting the liquid-cooled condenser (11) and liquid-cooled evaporator (12) of the refrigerant circuit to the vehicle's cooling circuit (2) upstream and / or downstream of the radiator (7), and by using the refrigerant circuit (9) to lower the coolant's temperature in the vehicle's cooling circuit (2) downstream of the radiator (7). The invention relates also to a system for cooling of coolant in a vehicle.

Description

technical field [0001] The present invention relates generally to cooling systems in vehicles and in particular to cooling systems comprising at least one compressor driven closed refrigerant circuit with a condenser and an evaporator. More particularly, the present invention relates to methods and systems for additional cooling of coolant in a vehicle cooling system so that components in the vehicle, typically cooled by air-cooled low-temperature radiators, may be cooled more efficiently. Background technique [0002] The development of vehicles is proceeding towards more and more advanced and complex systems for better functionality, higher efficiency, etc. This is not only applied to large, heavy and commercial vehicles, but can involve control components, intercoolers, EGR coolers, etc. Many of these components generate heat which must be cooled down in a suitable manner. [0003] These components are usually connected to a so-called passive cooling system in the vehic...
