For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific situation.
[0040] In a first aspect, this application provides a liquid storage device.
[0041] Combined Figure 1 and Figure 2 As shown, the liquid storage device provided by this application includes a liquid storage cylinder body 1, a liquid storage straight pipe 2, and a plurality of partition plates 3.
[0042] An air inlet 11 is provided at the first end of the liquid storage cylinder body 1, and an avoidance port 12 is provided at the second end of the liquid storage cylinder body 1.
[0043] The liquid storage straight pipe 2 is fixedly arranged inside the liquid storage cylinder body 1 along the axial direction of the liquid storage cylinder body 1. The inlet end 21 of the liquid storage straight pipe 2 is close to the air inlet 11, and the outlet end 22 of the liquid storage straight pipe 2 extends to the avoidance port 12.
[0044] The refrigerant mixture enters the inside of the liquid storage cylinder body 1 through the air inlet 11. Among them, the gaseous refrigerant enters the liquid storage straight pipe 2 through the inlet end 21 and flows out of the liquid storage straight pipe 2 through the outlet end 22, and then enters the air inlet of the compressor. The liquid refrigerant is stored inside the liquid storage cylinder body 1.
[0045] The partition plate 3 is sleeved on the liquid storage straight pipe 2. A through hole 31 is provided at the center of each partition plate 3, and along the inlet end 21 to the outlet end 22, the inner diameter of the through hole 31 gradually increases or gradually decreases according to the power function law.
[0046] In the case of adopting the above technical solution, the interior of the liquid accumulator provided by the present application is provided with a plurality of partitions 3 with through holes, and along the axial direction of the liquid accumulator cylinder 1, the inner diameter of the through holes 31 gradually increases or decreases according to the power function law. The plurality of through holes 31 changing according to the power function law can construct an acoustic black hole inside the liquid accumulator cylinder 1. When noise propagates along the acoustic black hole, the speed gradually slows down, the energy is effectively dissipated, and finally the noise is significantly attenuated or even completely eliminated. By setting an acoustic black hole inside the liquid accumulator cylinder 1 in this solution, the noise reduction performance of the liquid accumulator can be improved without changing the appearance of the compressor. It has a good noise reduction effect on liquid accumulators with or without coupled resonance problems, and has a wide adaptation range.
[0047] In some embodiments, as shown in Figure 3 , L = a * t, where L is the distance between two adjacent partitions 3, a is a constant and the value range of a is 5 to 10, and t is the thickness of the partition 3. For example, a is 5, 6, 7, 8, 9 or 10.
[0048] In this way, the distance between two adjacent partitions 3 can be controlled within a reasonable range, ensuring the noise reduction effect of the acoustic black hole composed of a plurality of partitions 3. At the same time, the weight of the liquid accumulator can also be controlled within a suitable range, avoiding the influence of the too large weight of the liquid accumulator on the resonance frequency of the liquid accumulator. If the distance between two adjacent partitions 3 is too large, it is difficult to achieve the expected noise reduction effect. If the distance between two adjacent partitions 3 is too small, the partitions 3 are too dense, resulting in a relatively large weight of the liquid accumulator, affecting the resonance frequency of the liquid accumulator.
[0049] In some embodiments, as shown in Figure 2 and Figure 3 , the distance L1 between the partition 3 closest to the suction port 11 and the suction port 11 is greater than the distance L2 between the inlet end 21 and the suction port 11. That is, L1 > L2. In this way, it is possible to prevent the liquid refrigerant from entering the straight pipe 2 of the liquid accumulator, causing liquid slugging in the compressor.
[0050] In some embodiments, as shown in Figure 2 and Figure 3 , r min 2 ≥0.5 * d 2 , where r min is the minimum radius of the through hole 31, and d is the diameter of the straight pipe 2 of the liquid accumulator.
[0051] By setting in this way, the gap between the partition 3 and the straight pipe 2 of the liquid accumulator can be kept within a reasonable range, and further the flow resistance of the liquid refrigerant can be kept within a reasonable range, ensuring the smooth downward flow of the liquid refrigerant along the gap.
[0052] In some embodiments, as shown in Figure 3 , rmax ≤b*R, where r max is the maximum radius of the through hole 31, b is a constant and the value range of b is 0.23 to 0.26, and R is the inner diameter of the liquid storage cylinder body 1. For example, b is 0.23, 0.24, 0.25 or 0.26, etc. With such a setting, the convenience of manufacturing and assembling the partition 3 can be ensured.
[0053] In some embodiments, when the inner diameter of the through hole 31 gradually increases according to the power function law along the inlet end 21 to the outlet end 22, the change of the radius of the through hole 31 satisfies the following relational expression:
[0054] Z n =-L1-K*(x n +r min ) m (1)
[0055] Z n =-L1-(n - 1)*L(2)
[0056] x n =-r n (3)
[0057] where n is the serial number of the partition 3 along the inlet end 21 to the outlet end 22, n = 2, 3, 4, 5...; Z n is the distance from the center of the nth partition 3 to the center of the air inlet 11; x n is the distance from the edge of the through hole 31 of the nth partition 3 to its center; that is, as shown in Figure 3 , the coordinate origin of the coordinate system referred to by this relational expression is the center of the air inlet 11, the Z axis passes through the coordinate origin and extends along the axial direction of the liquid storage cylinder body 1, and the x axis and the y axis respectively pass through the coordinate origin and extend along the radial direction of the liquid storage cylinder body 1. r n is the radius of the through hole 31 of the nth partition 3; L1 is the distance between the partition 3 closest to the air inlet 11 and the air inlet 11; r min is the minimum radius of the through hole 31; L is the distance between two adjacent partitions 3; k is a constant and 0.9 ≤ k ≤ 1.1; m is the power exponent, 2 ≤ m ≤ 4. For example, k is 0.9, 0.95, 1.0, 1.06 or 1.1, etc. M is 2, 2.5, 3 or 4, etc.
[0058] By making the change of the through hole 31 satisfy the above relationship, along the inlet end 21 to the outlet end 22, the inner diameter of the through hole 31 gradually increases according to the power function law, and an acoustic black hole can be constructed inside the liquid storage cylinder body 1, which has a good noise reduction effect on the liquid storage device.
[0059] In some embodiments, when the inner diameter of the through hole 31 gradually decreases according to a power function from the inlet end 21 to the outlet end 22, the change in the radius of the through hole 31 satisfies the following relationship:
[0060] Z n =-L1+K*(x n +r min ) m (4)
[0061] Z n =-L1+(n-1)*L(5)
[0062] x n =-r n (6)
[0063] Wherein, n is the serial number of the partition plate 3 along the inlet end 21 to the outlet end 22, n=2, 3, 4, 5, ...; Z n x is the distance between the nth partition 3 and the center of the air inlet 11; n is the distance from the edge of the through hole 31 of the nth partition 3 to its center; that is, combined Figure 3 As shown, the coordinate origin of the coordinate system referred to by the relational expression is the center of the air inlet 11, the Z axis passes through the coordinate origin and extends along the axial direction of the liquid reservoir cylinder 1, and the x axis and the y axis pass through the coordinate origin and extend along the radial direction of the liquid reservoir cylinder 1. n is the radius of the through hole 31 of the nth partition 3; L1 is the distance between the partition 3 closest to the air inlet 11 and the air inlet 11; r min is the minimum radius of the through hole 31; L is the distance between two adjacent partitions 3; k is a constant and 0.9≤k≤1.1; m is a power exponent, 2≤m≤4.
[0064] By making the change of the through hole 31 satisfy the above relationship, the inner diameter of the through hole 31 gradually decreases according to the power function law from the inlet end 21 to the outlet end 22, so that an acoustic black hole can be constructed inside the liquid reservoir cylinder 1, which has a good noise reduction effect on the liquid reservoir.
[0065] Wherein, the above formula (4) is the Z of the through hole 31 n The radius of the through hole 31 can be solved by combining the above formulas (4), (5) and (6). The specific solution process is as follows:
[0066] Substituting formula (2) and formula (3) into formula (1), we can obtain:
[0067] -L1+(n - 1)L=-L1+K*(-r n +r min ) m (7)
[0068] Simplifying the above formula (7) gives:
[0069] (n - 1)L = K*(-r n +r min ) m
[0070] Further simplifying and transforming gives:
[0071]
[0072] According to this formula, determine the values of K, L, m, and r min and other parameters, determine the serial number n of the partition, and then substitute each parameter into this formula to solve for r n .
[0073] In some embodiments, as shown in Figure 4 , a plurality of micro - through - holes are provided on the partition 3. By providing the micro - through - holes, the function of frequency shift can be achieved, adjusting the effective noise - elimination frequency band, thereby improving the noise - elimination effect.
[0074] In some embodiments, as shown in Figure 2 , the liquid reservoir further includes an intake pipe 4 and a liquid - reservoir elbow 5. The intake pipe 4 is arranged outside the liquid - reservoir cylinder body 1 and is communicated with the intake port 11 of the liquid - reservoir cylinder body 1. The liquid - reservoir elbow 5 is arranged outside the liquid - reservoir cylinder body 1 and is communicated with the outlet end 22 of the liquid - reservoir straight pipe 2.
[0075] The intake pipe 4 is arranged outside the liquid - reservoir cylinder body 1 and is communicated with the intake port 11 of the liquid - reservoir cylinder body 1. The intake pipe 4 can be connected to other components to introduce the refrigerant into the liquid - reservoir cylinder body 1. The liquid - reservoir elbow 5 is arranged outside the liquid - reservoir cylinder body 1 and is communicated with the outlet end 22 of the liquid - reservoir straight pipe 2. The liquid - reservoir elbow 5 is also connected to the compressor main body. In this way, the gaseous refrigerant can be led out, and the gaseous refrigerant can enter the compressor.
[0076] Embodiment 1
[0077] As shown in Figure 5 , the liquid reservoir is provided with 18 partitions 3. The thickness t of the partition 3 is 0.8 mm, the distance L between two adjacent partitions 3 is 7.5*t. The partition 3 with the through - hole 31 having the minimum radius is close to the intake port 11 of the liquid - reservoir cylinder body 1. Along the inlet end 21 to the outlet end 22, the inner diameter of the through - hole 31 gradually increases according to the power - function law. r min 2 = 0.5*d 2 , rmax = 0.254 * b. There are two options for the partition: with through - holes and without through - holes.
[0078] The variation of the radius of the through - hole 31 satisfies the following power function;
[0079] z n = - L1 - (x n + r min ) 2
[0080] z n = - L1 - (n - 1) * L
[0081] x n = - r n , n = 1, 2, 3... 18
[0082] Combined with Figure 6 as shown, the simulation results of the noise reduction transmission loss of the liquid reservoir show that the noise reduction of the two liquid reservoirs with the acoustic black hole partition group is significantly improved in the frequency range of 1640 Hz - 2450 Hz. Compared with the liquid reservoir with only the acoustic black hole partition group, the liquid reservoir with the acoustic black hole partition group + micro - through - holes has a frequency shift at the frequency point corresponding to the peak value of the noise reduction in the frequency range of 1640 Hz - 2450 Hz, playing a frequency - shifting role. In this solution, an acoustic black hole is constructed inside the liquid reservoir cylinder. When the noise propagates along the acoustic black hole, the speed gradually slows down and the energy is effectively dissipated, which can improve the noise reduction performance of the liquid reservoir without changing the appearance of the compressor.
[0083] Example 2
[0084] Combined with Figure 7 as shown, the liquid reservoir is provided with 18 partitions 3. The thickness t of the partition 3 is 0.8 mm, the distance L between two adjacent partitions 3 is 7.5 * t. The partition 3 with the through - hole 31 having the minimum radius is close to the avoidance port 12 of the liquid reservoir cylinder 1. Along the inlet end 21 to the outlet end 22, the inner diameter of the through - hole 31 gradually decreases according to the power function law. r min 2 = 0.5 * d 2 , r max = 0.254 * b. There are two options for the partition: with through - holes and without through - holes
[0085] The variation of the radius of the through - hole 31 satisfies the following power function;
[0086] z n = - L1+(x n + r min ) 2
[0087] z n = - L1+(n - 1) * L
[0088] x n = -r n where n = 1, 2, 3... 18
[0089] Combined with Figure 8 As shown, the simulation results of the noise reduction transmission loss of the liquid reservoir show that the noise reduction of the two liquid reservoirs with the acoustic black hole partition group is significantly improved in the frequency range of 1640 Hz to 2450 Hz. Compared with the liquid reservoir with only the acoustic black hole partition group, the liquid reservoir with the acoustic black hole partition group + micro-through holes has a frequency shift at the frequency point corresponding to the peak value of the noise reduction in the frequency range of 1640 Hz to 2450 Hz, playing a frequency shift role. In this solution, an acoustic black hole is constructed inside the liquid reservoir cylinder, and when the noise propagates along the acoustic black hole, the speed gradually slows down and the energy is effectively dissipated, which can improve the noise reduction performance of the liquid reservoir without changing the appearance of the compressor.
[0090] In a second aspect, the present application provides a compressor.
[0091] Combined with Figure 1 As shown, the compressor provided by the present application includes the liquid reservoir of any of the above embodiments. The compressor further includes a compressor main body, and the suction port of the compressor main body is communicated with the liquid reservoir.
[0092] In the case of adopting the above technical solution, a plurality of partitions 3 with through holes are arranged inside the liquid reservoir of the compressor provided by the present application, and along the axial direction of the liquid reservoir cylinder 1, the inner diameter of the through holes 31 gradually increases or decreases according to the power function law. The plurality of through holes 31 changing according to the power function law can construct an acoustic black hole inside the liquid reservoir cylinder 1. When the noise propagates along the acoustic black hole, the speed gradually slows down, the energy is effectively dissipated, and finally the noise is significantly attenuated or even completely eliminated. By setting the acoustic black hole inside the liquid reservoir cylinder 1 in this solution, the noise reduction performance of the liquid reservoir can be improved without changing the appearance of the compressor, and it has a good noise reduction effect on the liquid reservoir with or without the coupling resonance problem, and has a wide application range.
