Claims15
A thermal management system for a vehicle as a cooling system for cooling electronic components necessary for autonomous travelling of the vehicle, the thermal management system comprising:
- a first compressor for inhaling and compressing refrigerant and discharging out the compressed refrigerant in a gaseous state of high temperature and high pressure, a condenser for condensing the refrigerant, a first expansion valve for expanding the refrigerant, and a chiller for absorbing heat by exchanging heat between the refrigerant and coolant, which are disposed in a first refrigerant line in order,
- wherein the condenser is a water cooled condenser for radiating heat by exchanging heat between the refrigerant and the coolant,
- further comprising:
- a first coolant line passing through the chiller while exchanging heat with the electronic components;
- and a second coolant line, to which a low-temperature radiator for exchanging heat between the coolant and air is connected, and which passes through the water cooled condenser,
- wherein the coolant exchanges heat with the chiller of the first refrigerant line or exchanges heat with the air using the low-temperature radiator by being connected with the second coolant line,
- wherein the first coolant line and the second coolant line are selectively communicated with each other,
- wherein a third coolant line branches off from the first coolant line at the upstream side of the chiller and is connected to the second coolant line at the upstream side of the low-temperature radiator,
- wherein a fourth coolant line branches off from the second coolant line at the downstream side of the low-temperature radiator and is connected to the first coolant line at the downstream side of the chiller.
