An embodiment heat pump system of a vehicle includes a valve controlling a flow of a coolant, a first line having ends connected to the valve, a radiator and an electrical component on the first line, a second line having ends connected to the valve, a battery module on the second line, a first connection line including a first end connected to the valve, a chiller on the first connection line, a second connection line including ends connected to the second and first connection lines, and a third connection line including a first end connected to a second end of the first connection line and a second end connected to the first line between the radiator and the electrical component, wherein the valve operates such that the first, second, or first connection line is connected to another line or to itself depending on the selected mode.

Heat pump system for vehicle

An embodiment heat pump system for a vehicle includes a first cooling apparatus that circulates a first coolant in a first coolant line to control a temperature of an electrical component, a second cooling apparatus that circulates a second coolant in a second coolant line to control a temperature of a battery module, a third cooling apparatus that circulates a third coolant in a third coolant line to control a temperature of an autonomous driving controller, and an air conditioning device that circulates a refrigerant along a first refrigerant line to control an indoor temperature of the vehicle, the air conditioning device including a compressor, a condenser, a first expansion valve, and an evaporator all connected through the first refrigerant line, and further including a first chiller, a second chiller, and a connection line.

Disclosed herein is a heat pump system for a vehicle having a battery module and an electric module. The heat pump system includes: a first cooling line connected to the battery module and having a coolant flowing therein; a chiller disposed on the first cooling line and connected to a refrigerant line of an air conditioning system through a connection line, and exchanging heat between a coolant selectively introduced therein and a refrigerant to control a temperature of the coolant; a cooling system including a radiator connected to a cooling line and a first pump circulating the coolant along the second cooling line so as to cool an electric module, and connected to the first cooling line through a first valve; and a bypass line selectively connecting the connection line and the refrigerant line to each other through a second valve provided on the refrigerant line.

A battery cooling system for a vehicle may include an air conditioning device including a compressor, a condenser, an evaporator, and a first expansion valve connected through a refrigerant line and circulating a refrigerant to cool the internal of the vehicle; a cooler including an electric device radiator and a first water pump connected with a cooling line and circulating coolant to cool a motor and an electric device; a battery module in which the coolant circulated therein through an operation of a second water pump provided on a battery cooling line, connected with the cooling line through the battery cooling line; and a chiller connected with the refrigerant line through a connection line, provided on the battery cooling line, and controlling a temperature of the coolant by heat-exchanging the coolant and the refrigerant selectively introduced thereinto.

Battery cooling system for vehicle

A heat pump system for a vehicle includes: a battery cooling line connected with a battery module, and water flowing through the battery cooling line; a chiller provided at the battery cooling line, connected with a coolant line of an air conditioner through a connection line, and configured to control the cooling water selectively introduced into the chiller by heat-exchanging the cooling water with coolant; a cooling part comprising a radiator and a first water pump connected with each other by a cooling line, configured to circulate the water through the cooling line to cool an electrical device, and connected with the battery cooling line through a first valve; and a bypass line configured to selectively connect the connection line with the coolant line through a second valve provided at the coolant line.
