Abstract
A vehicle thermal management system is disclosed comprising a first and a second coolant circuit each comprising a coolant pump. The first coolant circuit comprises a coolant duct configured to conduct coolant flow through a portion of the first coolant circuit, and an expansion tank connected to the coolant duct. The system further comprises a first connecting conduit connecting the second coolant circuit to the coolant duct, and valve controllable between a first state in which the valve hinders flow of fluid through the first connecting conduit, and a second state in which the valve allows flow of fluid through the first connecting conduit. The present disclosure further relates to a vehicle comprising a vehicle thermal management system.
Claims20
A vehicle thermal management system comprising:
- a first and a second coolant circuit each comprising a coolant pump,
- wherein the first coolant circuit comprises:
- a coolant duct configured to conduct coolant flow through a portion of the first coolant circuit;
- and
- an expansion tank connected to the coolant duct;
- a first connecting conduit connecting the second coolant circuit to the coolant duct of the first coolant circuit;
- and
- a valve controllable between a first state in which the valve hinders flow of fluid through the first connecting conduit, and a second state in which the valve allows flow of fluid through the first connecting conduit and through at least a portion of the coolant duct and thereafter to the expansion tank to deair the second coolant circuit via the expansion tank,
- wherein the first connecting conduit comprises a first end and a second end, wherein the second end is connected to the second coolant circuit via a connection arranged upstream of the coolant pump of the second coolant circuit relative to an intended flow direction through the second coolant circuit.
A vehicle comprising a vehicle thermal management system comprising:
- a first and a second coolant circuit each comprising a coolant pump,
- wherein the first coolant circuit comprises:
- a coolant duct configured to conduct coolant flow through a portion of the first coolant circuit;
- and
- an expansion tank connected to the coolant duct;
- a first connecting conduit connecting the second coolant circuit to the coolant duct of the first coolant circuit;
- and
- a valve controllable between a first state in which the valve hinders flow of fluid through the first connecting conduit, and a second state in which the valve allows flow of fluid through the first connecting conduit and through at least a portion of the coolant duct and thereafter to the expansion tank to deair the second coolant circuit via the expansion tank,
- wherein the first connecting conduit comprises a first end and a second end, wherein the second end is connected to the second coolant circuit via a connection arranged upstream of the coolant pump of the second coolant circuit relative to an intended flow direction through the second coolant circuit.
A vehicle thermal management system comprising:
- a first and a second coolant circuit each comprising a coolant pump, wherein the first coolant circuit comprises:
- a coolant duct configured to conduct coolant flow through a portion of the first coolant circuit;
- and an expansion tank connected to the coolant duct;
- a first connecting conduit connecting the second coolant circuit to the coolant duct of the first coolant circuit;
- a valve controllable between a first state in which the valve hinders flow of fluid through the first connecting conduit, and a second state in which the valve allows flow of fluid through the first connecting conduit and through at least a portion of the coolant duct and thereafter to the expansion tank to deair the second coolant circuit via the expansion tank;
- and
- a second connecting conduit fluidly connecting the second coolant circuit to the coolant duct, wherein the second connecting conduit is configured to supply coolant from the coolant duct to the second coolant circuit and the first connecting conduit is configured to return coolant from the second coolant circuit to the coolant duct when the valve is in the second state.
