The heat exchanger unit 110 having such a configuration may be in a plate form (or also referred to as a "plate heat exchanger") having a plurality of stacked plates 112 be formed.

Here, the working fluid may be a cooling water which has been cooled by a radiator in a vehicle cooling system.

In various embodiments, the first and second inlets are 118a and 118b on one side of the heat exchanger unit 110 so that the refrigerant and the working fluid flow into the inner portion, and each of them is with the first and second flow paths, respectively 114 and 116 connected.

In addition, the first and the second outlet 119a and 119b each on a different side of the heat exchanger unit 110 corresponding to the first and the second inlet 118a and 118b shaped and with the first and the second flow path 114 and 116 connected, so that the working fluid and the refrigerant, which is the heat exchanger unit 110 happen, can be led out.

Although in various embodiments, the heat exchanger unit 110 however, as will be described with two flow paths, two inlets and two outlets as an exemplary embodiment, it will be understood that other suitable configurations may be used.

In addition, although in various embodiments the working fluid has been described as a cooling water as an exemplary embodiment, it is to be understood that other suitable configurations may be used.

In addition, the noise reduction unit 120 on one side of the heat exchanger unit 110 corresponding to the first inlet 118a is provided, in which the refrigerant flows to reduce noise and vibration, which are generated when the refrigerant supplied from the compressor moves.

As in 1 and 3 shown is the noise reduction unit 120 configured to have: a cover unit 122 , a connection hole 123 , a partition 126 and a reduction hole 128 and each configuration for the components will be described in detail below.

Due to the noise and vibration generated when a fluid is moved along the travel path, the standing waves are introduced into a closed and sealed space connected by a small entrance or hole formed on the path of travel. At this time, the noise and the vibration of the inverse frequency of the standing wave are generated, and the noise of a specific frequency band (mainly high frequency range) is canceled by the inverse frequency.

That is, in various embodiments of the present invention, the noise reduction unit is 120 integral to the heat exchanger unit 110 configured so that the noise and vibration can be reduced when the refrigerant is moved.

Accordingly, the refrigerant used in the air conditioning system of the vehicle can condense by heat exchange with the working fluid, and the noise and the vibration generated when the refrigerant moves can be simultaneously reduced by the noise reduction unit 120 so as to enable the overall NVH performance of the vehicle to be improved.

In addition, since the noise and the vibration generated during the movement of the refrigerant, by means of the noise reduction unit 120 can be reduced, which integral in the heat exchanger 100 is configured without mounting a separate silencer, a space utilization can be improved by simplifying a layout in a narrow engine compartment.
