Abstract: Disclosed is a four-way valve including a housing having a refrigerant filling chamber formed therein, a high pressure pipe hole formed on a bottom surface of the housing and coupled to a high pressure pipe through which refrigerant discharged from the compressor flows, a first pipe hole formed on an upper surface of the housing and coupled to a first pipe extending to a first heat exchanger, a second pipe hole formed on the upper surface of the housing and coupled to a second pipe extending to a second heat exchanger, a low pressure pipe hole formed on the upper surface of the housing and configured to allow the refrigerant to be collected to the compressor, and a switching guide configured to rotate to allow the low pressure pipe hole to selectively communicate with the first pipe hole or the second pipe hole.

Abstract: A motor includes: a motor housing; a shaft disposed inside the motor housing and extending along a rotation axis; a rotor having magnetism, and coupled to an outer circumferential surface of the shaft; a stator accommodated in the motor housing, disposed to be spaced apart from an outside of the rotor in a radial direction of the shaft, and wound around with a coil; a nozzle for charging a cooling fluid by applying a voltage, and spraying the cooling fluid to at least one of the rotor and the stator; and a charging plate disposed to be spaced apart from a spray hole of the nozzle, and changes a spray form of the cooling fluid by applying a voltage.

Abstract: The present disclosure relates to a heat pump device for an electric vehicle, and more particularly, to a heat pump device that constitute three types of independent refrigerant cycle in which three different types of refrigerant flow respectively, and disposes a first heat exchange unit and a second heat exchange unit in which the refrigerants exchange heat with each other, in the refrigerant cycle, thereby performing an integrated heat management of an indoor space, a battery, and a driving module.

Abstract: Disclosed is a heat pump system for an electric vehicle including an outdoor fan configured to blow air to an outdoor heat exchanger, a coolant temperature sensor installed at a coolant line and configured to detect a temperature of a coolant circulating in a power train module or a battery, an outdoor heat exchange sensor installed on one side of the outdoor heat exchanger and configured to detect an outdoor heat exchanger outlet pressure defined as a pressure of a refrigerant passing through the outdoor heat exchanger, and a compressor inlet sensor installed on an intake side of a compressor and configured to detect a compressor inlet temperature defined as a temperature of the refrigerant flowing into the compressor. Whether frost sticking occurs may be determined based on information detected by the coolant temperature sensor, the outdoor heat exchange sensor, and the compressor inlet sensor.

Abstract: Disclosed is a heat pump system including a compressor configured to compress a refrigerant, a four-way valve configured to switch a flow direction of the refrigerant discharged from the compressor, an outdoor heat exchanger and an indoor heat exchanger each having one side connected to the four-way valve, an auxiliary heat exchanger connected to the four-way valve by an accumulation pipe and having an internal space filled with a refrigerant from the accumulation pipe, an outdoor pipe extending from the other side of the outdoor heat exchanger, an indoor pipe extending from the other side of the indoor heat exchanger, and a flow pipe branched from an outdoor branch point of the outdoor pipe and extending to an indoor branch point of the indoor pipe.
