With reference to figure 3, the pumping muffler that is used for compressor comprises a following chamber 110, and this time chamber has an inlet 111 that is connected to the inner space of compressor room's (not shown), is used to suck refrigerant; Go up chamber 120 for one, cover down the top of chamber 110, and have an outlet 121 that is connected to the suction side that is formed at the cylinder block (not shown) in the compressor bank; And be attached to down chamber 110 or go up the tube passage 130 of chamber 120, be used for directly will descending the inlet 111 of chamber 110 to be connected to the outlet 121 of chamber 120.
The inlet duct 112 that links to each other with the inner space of compressor room is connected to down the inlet 111 of chamber 110, and outer pipe 122 stretches out from the outlet 121 of last chamber 120, and this outer pipe 122 holds the suction valve of compressor bank and is connected to the suction side of cylinder block.
Divider 140 is installed in down the top of chamber 110, is used for chamber 110 and last chamber 120 are separated into resonant cavity S down.
As shown in Figure 4, divider 140 is placed on the first step part 113 on the upper inside wall that is formed at down chamber 110, and the second step part 123 that this divider is formed on the opening side of chamber 120 is pushed down securely.
Tube passage 130 is to make separately, and is linked to down on the chamber 110.To this still with reference to figure 4, a plurality of fixed projections 131 are side-prominent from the excircle two of the outlet side of tube passage 130, the fixed projection 131 of tube passage 130 slidably is inserted into fixed groove 114 along the vertical direction, fixed groove 114 be formed at down the inwall of chamber 110 and contact with this time chamber 110 and overlapped divider 140 on, perhaps be formed at down on any one in chamber 110 and the divider 140.
As shown in Figure 5, divider 140 can be formed on down on the vertical direction of chamber 110 and last chamber 120, and combines with each chamber body 110 and 120.At this, the divider of the divider of following chamber side and last chamber side must be in contact with one another, so that the inner space of chamber body is separated.
Tube passage 130 can merge with divider 140, and divider 140 can be linked on the body of chamber.That is to say that as shown in Figure 6, the enough wide divider 140 of chamber 110 and last chamber 120 combines with the excircle in the outside of tube passage 130 under separating.Divider 140 is placed on down the first step part 113 of chamber 110, and is pushed down regularly by the second step part 123 of last chamber 120.Do not need described fixing outstanding and fixed groove at this, this has simplified processing and assembling.
Preferably, as shown in Figure 7, the excircle of tube passage 130 separates with the internal surface of predetermined interval with following chamber 110 and last chamber 120, to form air layer.Air layer is used to prevent that the interior heat of compressor room is transmitted to refrigerant.
At least one micro through hole 132 is formed on the tube passage 130 along the longitudinal direction, is used to cut down backflow noise or pressure pulsation.Preferably, the diameter of micro through hole 132 is far smaller than the internal diameter of tube passage 130.
Preferably, as shown in Figure 8, tube passage 130 forms with the shape of straight line, and guiding gutter 133 is formed on the inner circumference of tube passage 130 with spiral or straight line shape, so that suck refrigerant apace.
On the other hand, though do not illustrate, tube passage 130 and divider 140 can merge with following chamber 110.Yet if the angular positioning of entrance and exit to be scheduled to, tube passage 130 must make manufacture process complicate with this angle tilt so so.Therefore, it is favourable making and assemble these parts separately.
The pumping muffler that is used for compressor according to the present invention has following operational effect.
When the compressor bank (not shown) in being installed in compressor room is driven, the refrigerant that is inhaled into the compressor room inner space is inhaled in the tube passage 130 by inlet duct 112, directly supply with by tube passage 130 and to give outer pipe 122, the unlatching of the suction valve (not shown) by compressor is inhaled into the compression volume of cylinder then.
Because tube passage 130 forms with the shape of straight line, the refrigerant of compressor room can be drawn in the compressor bank fast.When sucking refrigerant, produce various noises and vibration, for example, by opening and shut the valve noise that the suction valve produces, the hydrodynamic noise that produces by the suction of refrigerant, and the pressure pulsation that is produced by the periodic repeat aspiration operation of compressor refluxes along the tube passage 130 of pumping muffler.Yet valve noise and pressure pulsation are cancelled by tube passage 130, and additionally the micro through hole 132 at the middle part by being formed on tube passage 130 is fed into resonant cavity S in the inner space that is formed at down chamber 110 and last chamber, and are cancelled there.
Below should operation with more detailed description.Traditional pumping muffler has complicated suction channel.When refrigerant spread in the whole resonant cavity S of following chamber 11 and last chamber 12, the flow resistance of refrigerant increased, thereby has produced suction loss.Yet according to the present invention, when the refrigerant of the compressor room linear tube passage 130 by pumping muffler directly was drawn in the cylinder block, most of refrigerant was collected into outlet 121 and is shifted fast.Therefore, the intake of refrigerant increases significantly.Following form shows conventional art with of the present invention different.
Conventional art The present invention
Mass flow rate [Grams Per Second] 3.234 4.588
Ratio [%] 100 131
That is to say that the pumping muffler that utilizes tube passage to simplify suction channel of the present invention has increased by about 31% mass flow rate than having the logical road tradition pumping muffler of complicated suction more.Especially, as shown in Figure 8, when the refrigerant guiding gutter with the spiral-shaped inner circumference that is formed at tube passage on the time, refrigerant can move faster.The result is the intake that has increased refrigerant.
Because the refrigerant of compressor room flows through the tube passage in the pumping muffler, therefore between the body of the chamber of tube passage and pumping muffler, formed air layer, stoped interior passage of heat thus from compressor room.The rising of the inlet temperature by preventing refrigerant, the suction loss of refrigerant can more reduce.
