The present invention relates to an air foil journal bearing comprising a bump foil and a top foil, wherein one end and the other end of the top foil in the circumferential direction are arranged with a step difference from each other in the radial direction, and assuming that the direction in which the top foil extends from one end to the other end and the direction of rotation of a rotor disposed inside the top foil and rotated are the same, the one end of the top foil is disposed more inward than the other end of the top foil in the radial direction, so that additional fluid dynamic pressure is generated inside the bearing to suppress asynchronous vibration components which affect noise during high-speed driving, thereby improving driving stability.
An embodiment provides a vehicle heat management device comprising: a compressor that compresses and circulates a refrigerant; a first heat exchanger into which the compressed refrigerant flows and exchanges heat with another heat exchange medium; a second heat exchanger that exchanges heat with air outside a vehicle interior; a third heat exchanger that is installed in an air conditioner and exchanges heat with air discharged into the vehicle interior; and a vapor injection module that can make a gaseous refrigerant flow into the compressor. The vapor injection module includes a plurality of expansion means and a gas-liquid separator. In a cooling mode, refrigerant that has passed through the second heat exchanger flows into the vapor injection module. In a heating mode, refrigerant that has passed through the first heat exchanger flows into the vapor injection module. Accordingly, the vehicle heat management device can be compact while having improved cooling and heating performance.
