Fig. 2 to Fig. 7 is a specific embodiment of the utility model embodiment coolant distribution device, the refrigerant in the present embodiment
Current divider, including body 1, example, body 1 can use brass material to make, and refrigerant flow channel 2, refrigerant are provided with body 1
Flow channel 2 is included respectively positioned at first opening 21 at itself both ends and the second opening 22, and the first opening 21 is used for and expansion valve
(not shown) connects, and the second opening 22 is multiple, is used to be connected with evaporator (not shown), from the first opening 21
Flow into the refrigerant of refrigerant flow channel 2 uniformly can be additionally provided with sound insulation groove 3, sound insulation out of the outflow of the multiple second opening 22, body 1
Groove 3 does not connect with the refrigerant flow channel 2 positioned at its opposite sides and the outer surface of body 1.
The coolant distribution device that the utility model embodiment provides, due to being additionally provided with sound insulation groove 3, sound insulation groove 3 and position in body 1
Do not connected with the outer surface of body 1 in the refrigerant flow channel 2 of its opposite sides, i.e. the setting of sound insulation groove 3 does not interfere with cold
The original shunting effect of matchmaker's current divider, therefore when the inner surface of the refrigerant impact refrigerant flow channel 2 of gas-liquid mixed produces very
During strong liquid stream noise, sound insulation groove 3 can separate the path that liquid stream noise is outwards propagated, so that the liquid stream that can be blazed abroad
Noise is reduced, that is, reduces noise, and then improve Consumer's Experience.
Preferably, sound insulation groove 3 is annular, and around around refrigerant flow channel 2, so that sound insulation groove 3 can
The path that cut-off liquid stream noise is outwards propagated from different directions, so as to which the liquid stream noise for further allowing to blaze abroad is reduced,
And then further improve Consumer's Experience.
For reference picture 2 to Fig. 7, body 1 includes interflow part 11 and position of splitter 12, and position of splitter 12 is set close to one end of interflow part 11
There is mounting groove A, interflow part 11 is installed in mounting groove A close to the one end fits of position of splitter 12, and the second of refrigerant flow channel 2 opens
Mouth 22 is in position of splitter 12, and on the part 11 of interflow, the side wall that interflow part 11 is located in mounting groove A is provided with remainder
Depressed part B, depressed part B and mounting groove A inner surface surround sound insulation groove 3 jointly；It is straight compared on interflow part 11 or position of splitter 12
Connect and process sound insulation groove 3, the present embodiment first interflow part 11 on processes the less depressed part B of difficulty, then make depressed part B with
Position of splitter 12 surrounds sound insulation groove 3 jointly, can so reduce difficulty of processing, so as to facilitate processing.
In order to further lift Consumer's Experience, reference picture 3 and Fig. 4, refrigerant flow channel 2 also includes being located in the present embodiment
First opening 21 and the second jet orifice 23 and distribution cavity 24 for being open between 22 and interconnecting, jet orifice 23 and first are open
21 connections, distribution cavity 24 are all connected with the multiple second openings 22, and thus, the refrigerant flowed into from the first opening 21, which can pass sequentially through, to be penetrated
Discharge orifice 23 and distribution cavity 24 reach multiple second openings 22, then from the outflow of the multiple second opening 22；Jet orifice 23 is used for gas
A small amount of liquid is transformed into gas in the refrigerant of liquid mixing, so as to reduce the amount of liquid, and then subtracts caused liquid stream noise
It is small, also just further improve Consumer's Experience.The diameter of jet orifice 23 is preferably 4mm~4.5mm.
Reference picture 4, the one end of jet orifice 23 away from the first opening 21 is located in distribution cavity 24, so that distribution cavity 24
Region F around jet orifice 23 can separate the path that liquid stream noise is outwards propagated in jet orifice 23, so that can propagate out
The liquid stream noise gone is further reduced, that is, reduce further noise.
Distribution cavity 24 is preferably cylindrical, and compared to tubaeform shown in Fig. 3, the present embodiment increases the sky of distribution cavity 24
Between, so that liquid stream noise is not easily accessible to the cavity wall of distribution cavity 24, also just it is easily detected by cavity wall and spreads out of, equally reduce
Noise.
Dashpot C is provided with the first 21 relative positions of opening on mounting groove A bottom wall, thus can be C pairs by dashpot
Refrigerant enters row buffering, avoids refrigerant from being directly impinging physically, so that caused liquid stream noise reduces.
Reference picture 5 and Fig. 6, be provided with first step D positioned at the position of notch in mounting groove A side wall, collaborate on part 11 and
Position corresponding to first step D is provided with second step E, second step E and first step D mating connection, so that interflow part
11 is more firm with the connection of position of splitter 12, so that the structure of coolant distribution device is more firm.
For second step E and first step D preferably by Welding, brazing deformation is small, can make the size of coolant distribution device
It is more accurate.
The size of sound insulation groove 3 is bigger, corresponding better to the cut-off effect in liquid stream noise transmission path, therefore the present embodiment
In, along the radial direction of refrigerant flow channel 2, the size of sound insulation groove 3 is more than or equal to 1.5mm, thus can be lifted to liquid stream noise
The cut-off effect of propagation path.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
