Abstract
A cooling circuit including a combustion engine, a coolant cooler, a first thermostat, a first pump, a condenser, a second thermostat and a second pump, wherein a cooling agent can flow through the cooling circuit, wherein the combustion engine, first pump, coolant cooler and first thermostat are arranged in a first circuit, and the condenser, second thermostat and second pump are arranged in a second circuit, and wherein the first circuit and second circuit are in fluid communication with one another at at least one point.
Claims11
A cooling circuit comprising:
- a combustion engine;
- a coolant cooler;
- a first thermostat;
- a first pump;
- a condenser;
- a second thermostat;
- and
- a second pump,
- wherein a coolant is adapted to flow through the cooling circuit,
- wherein the combustion engine, the first pump, the coolant cooler and the first thermostat are arranged in a first circuit,
- wherein the condenser, the second thermostat and the second pump are arranged in a second circuit,
- wherein the first circuit and the second circuit are in fluid communication with one another at at least one point,
- wherein a coolant inlet and a coolant outlet are in fluid communication with the first circuit,
- wherein the coolant outlet is in fluid communication with a first bypass provided in the first circuit,
- wherein the second circuit is provided with a second bypass,
- wherein the first circuit includes a first section and a second section and the second circuit includes a third section and a fourth section,
- wherein the second thermostat has a first coolant outlet that directly opens into the second bypass and a second coolant outlet that directly opens into the fourth section, and
- wherein coolant flowing through the second bypass enters back into either the first circuit or the second circuit at a point that is downstream of the coolant cooler and coolant flowing through the fourth section enters back into the first circuit at a point that is downstream of the coolant cooler.
