Abstract
The utility model relates to the technical field of an air conditioner and provides a refrigerant distributor. The refrigerant distributor comprises a distribution head and a distribution nozzle. The distribution head comprises a distribution head body and a channel. The distribution nozzle comprises a distribution nozzle body, a containing cavity and a plurality of distribution holes. The channel is communicated with the distribution holes. The channel comprises an upper channel body, a middle channel body and a lower channel body. Both the bore of the upper channel and the bore of the lower channel are larger than the bore of the middle channel. A guiding inclined plane is arranged at the position where the upper channel is connected with the middle channel, wherein the guiding inclined plane contracts downwards. A distribution boss with a round head is arranged inside the containing cavity and is located in the centre of the distribution holes. According to the air conditioner and the refrigerant distributor thereof, the flow speed of a flow body is linearly improved through the guiding inclined plane, pressure is decreased, the flow speed is further decreased and the pressure is increased when the flow body enters the lower channel due to the fact that the bore of the lower channel is large, and noise is reduced through the lower channel, the distribution boss with the round head can distribute the flow body well, and particularly due to the fact that the distribution boss with the round head is provided with an arc-shaped surface, distribution resistance is reduced when the flow body passes through, impact force is reduced, and therefore vibration and noise are effectively reduced at the same time.
Description
Technical field

Particularly, the junction of described lower flow channel and described middle runner is the concave shaped cambered surface.
Particularly, the junction of described lower flow channel and described middle runner is the inclined-plane.
Particularly, the bore of described middle runner is d, and 4mm≤d≤5mm.
The utility model also provides a kind of air-conditioner, and described air-conditioner comprises the coolant distributor with said structure.
In the utility model, be provided with guiding surface in the upper runner of coolant distributor and middle runner junction, like this, when fluid flow to middle runner by upper runner, flow velocity is linear to be improved, and pressure decreased enters after lower flow channel because the lower flow channel bore is large, further deceleration diffusion, fully mix under the pressure differential effect like this, and have bigbore lower flow channel and be equivalent to a muffler, design different sizes, can eliminate the different sound of different-waveband, thereby reach good sound-deadening and noise-reducing effect; And be located at the round end shape shunting boss at each tap hole center, the fluid of flowing through is played shunting action preferably, and particularly round end shape shunting boss has the surface of arcuation, and fluid is reduced through the time-division flow resistance, impulsive force diminishes, therefore also effectively reduce vibration and noise.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Embodiment one
With reference to Fig. 1, the structural representation of shunt head 200 in the first coolant distributor 100 that provides for the utility model.Shunt head 200 comprises shunt head body 210 and connects the runner 220 of shunt head body 210, runner 220 comprises upper runner 221, middle runner 222 and lower flow channel 223 from top to bottom, the bore of upper runner 221 is greater than the bore of middle runner 222, the bore of lower flow channel 223 is greater than the bore of middle runner 222, upper runner 221 has with middle runner 222 junctions the guiding surface 224 that is contraction-like downwards, and lower flow channel 223 is concave shaped cambered surface 225 with the junction of middle runner 222.In the present embodiment, the bore of middle runner 222 is d, and 4mm≤d≤5mm.
With reference to Fig. 2, Fig. 3, the structural representation of shunting nozzle 300 in the first coolant distributor 100 that provides for the utility model.In the present embodiment, shunting nozzle 300 comprises shunting nozzle body 310, is located at the accommodating cavity 320 on shunting nozzle body 310 and is located at accommodating cavity 320 bottoms and connect a plurality of tap holes 330 of shunting nozzle body 310.Be provided with a round end shape shunting boss 340 in accommodating cavity 320.In the present embodiment, tap hole 330 is four, and four tap holes 330 evenly distribute centered by round end shape shunting boss 340, and the angle between adjacent two tap holes 330 is 90 °.Certainly, tap hole 330 also can be set to other quantity, as long as it evenly distributes centered by round end shape shunting boss 340.
