A protrusion is integrally formed on one surface of the heat exchanging part and protrudes toward a corner of the heat exchanging part at a position corresponding to the first inflow port. A cover plate forming;
A connecting hole formed on the protruding portion on the opposite side of the first inflow port to allow the refrigerant to flow into the refrigerant moving path; and
Partition walls that are formed to protrude toward one surface of the heat exchange part on both sides of the inner side surface of the refrigerant moving path, and form separate spaces on both sides inside the refrigerant moving path;
The partition is formed with a reduction hole that interconnects the refrigerant movement path and the space so that the refrigerant flowing into the space generates a frequency opposite to that of the refrigerant moving along the refrigerant movement path. characterized in that that a heat exchanger for a vehicle. The cover plate is
Corresponding to the first inlet and the second inlet, holes interconnected to the first inlet and the second inlet are respectively formed and stacked on one surface of the heat exchange unit. The vehicle heat exchanger according to claim 4 . In the air conditioner system in which the refrigerant circulates, it is provided between the compressor and the expansion valve,
A heat exchange section in which a first flow path and a second flow path are formed, and the refrigerant is condensed by mutual heat exchange between the refrigerant passing through the first flow path and the working fluid passing through the second flow path;
A first inlet and a second inlet formed on one surface of the heat exchange unit, allowing the refrigerant and the working fluid to flow into the interior and respectively connected to the first and second flow paths;
First and second outlets that are respectively formed on the other surfaces of the heat exchange unit and are interconnected with the first and second flow paths to discharge the refrigerant and the working fluid that have passed through the heat exchange unit. And a noise reduction unit that is provided on one surface of the heat exchange unit corresponding to the first inlet into which the refrigerant flows, and reduces noise and vibration generated when the refrigerant supplied from the compressor moves;
Only including,
