The utility model provides a suction muffler.
In an embodiment of the present invention, as shown in fig. 1 and 2, the suction muffler 10 includes a housing 200 and a partition assembly 300.
The housing 200 has a sound-deadening chamber 202 and an air inlet 204 and an air outlet 206 communicating with the sound-deadening chamber 202.
The partition member 300 is provided in the sound-deadening chamber 202, and partitions the sound-deadening chamber 202 into a first chamber 202a communicating with the air inlet 204 and a second chamber 202b communicating with the air outlet 206. The partition member 300 has a first flow passage 302 and a second flow passage 304 located outside the first flow passage 302, and the first flow passage 302 and the second flow passage 304 communicate with the first cavity 202a and the second cavity 202 b.
When the suction muffler 10 is used, the refrigerant enters the first cavity 202a through the inlet 204, then enters the second cavity 202b through the partition member 300, and finally exits through the outlet 206. Since the air inlet 204, the first cavity 202a, the partition member 300, and the second cavity 202b are engaged with the air outlet 206, the suction noise of the compressor is reduced. Moreover, compared with a flow passage only comprising the first flow passage 302, the composite flow passage simultaneously comprising the first flow passage 302 and the auxiliary second flow passage 304 has smaller fluid flow resistance, higher cold energy and lower inlet force, thereby improving the energy efficiency ratio of the compressor, and compared with a flow passage only comprising a large inner diameter (the flow area of which is approximately the same as the sum of the flow area of the first flow passage 302 and the flow area of the second flow passage 304), the composite flow passage simultaneously comprising the first flow passage 302 and the second flow passage 304 has higher acoustic impedance and better silencing effect. Therefore, the suction muffler 10 can achieve both noise and power consumption, and can reduce noise and achieve a high energy efficiency ratio.
In this embodiment, the second flow channel 304 is multiple, and the multiple second flow channels 304 are arranged at intervals and surround the first flow channel 302. Compared with the mode that only one second flow channel 304 is arranged on the outer side of the first flow channel 302, the mode that the plurality of second flow channels 304 are arranged at intervals and surround the first flow channel 302 can better take noise and energy consumption into consideration.
In this embodiment, the second flow channels 304 are arranged at intervals and surround the first flow channels 302 for a circle. Specifically, in the present embodiment, the plurality of second flow channels 304 are arranged at equal intervals. Thus, the refrigerant can flow more uniformly around the outer circumference of the first flow channel 302. It is understood that in other embodiments, the plurality of second flow channels 304 may surround the first flow channel 302 for a plurality of times, and is not limited to the plurality of second flow channels 304 surrounding the first flow channel 302 for one time.
In the present embodiment, the partition assembly 300 includes a communication pipe 310. The first flow passage 302 and the second flow passage 304 are both located on the communicating pipe 310. That is, in the present embodiment, the first flow channel 302 and the second flow channel 304 are integrated on the same communication pipe 310. For setting up two communicating pipes, a communicating pipe has first runner 302, another communicating pipe has the mode of second runner 304, first runner 302 and the mode that second runner 304 are integrated on same communicating pipe 310, can simplify the structure of separating subassembly 300, and more do benefit to and design first runner 302 as the mainstream way, and design second runner 304 as the secondary flow way, through the big runner area of mainstream way and the little and many little runner area synergy of secondary flow way, thereby can be better compromise noise and energy consumption.
In the present embodiment, the partition assembly 300 further includes a partition plate 320. The partition plate 320 is disposed in the sound-deadening chamber 202 and divides the sound-deadening chamber 202 into the first chamber 202a and the second chamber 202b, that is, the partition plate 320 is disposed at a boundary between the first chamber 202a and the second chamber 202 b. The communication pipe 310 is inserted through the partition plate 320. The provision of the partition plate 320 greatly facilitates the partition assembly 300 to partition the sound-deadening chamber 202 into the first chamber 202a and the second chamber 202 b. It is understood that, in other embodiments, when the area of the cross section of the communication pipe 310 is large enough to satisfy the requirement that the communication pipe 310 divides the sound-deadening chamber 202 into the first chamber 202a and the second chamber 202b, that is, when the communication pipe 310 integrates two functions of conducting and dividing the first chamber 202a and the second chamber 202b, the separation plate 320 may be omitted, and the effect of simplifying the structure of the partition assembly 300 is achieved.
In this embodiment, partition 320 has mounting hole 322 formed therein, and communication pipe 310 is inserted into mounting hole 322. The outer wall of the communication pipe 310 may or may not be hermetically connected to the inner wall of the mounting hole 322.

The communication pipe 310 is inserted through the partition plate 320. The first flow path 302 is located on the connection pipe 310, and the second flow path 304 is located on the separation plate 320. The difficulty of forming the second flow channel 304 on the partition plate 320 is low, and the second flow channel 304 is disposed on the partition plate 320, and the existing pipeline can be used as the communicating pipe 310, so that the communicating pipe 310 does not need to be additionally designed and/or manufactured, the difficulty of designing and/or manufacturing the partition assembly 300 can be reduced, and the effect of reducing the cost of the partition assembly 300 can be achieved.
In some embodiments, as shown in fig. 5, the partition plate 320 is formed with a plurality of second flow passages 304, and the plurality of second flow passages 304 are arranged at intervals and surround the communication pipe 310. The partition plate 320 is formed with a mounting hole 322. The mounting holes 322 are located in an area defined by the plurality of second channels 304. The connection pipe 310 having the first flow path 302 is inserted into the mounting hole 322. At this time, the outer wall of communication pipe 310 may be in sealed connection with the inner wall of mounting hole 322, or may not be in sealed connection with the inner wall of mounting hole 322, and when the outer wall of communication pipe 310 is not in sealed connection with the inner wall of mounting hole 322, gap flow channel 306 shown in fig. 3 or 4 is formed between the outer wall of communication pipe 310 and the inner wall of mounting hole 322, and gap flow channel 306 is located between first flow channel 302 and second flow channel 304.
