TH431A - Continuous curved surface gas compressor jacket to suppress noise. - Google Patents

Abstract

Air-tight gas compressor jacket It has a shape formed by forming of sheet metal, which is two machine covers, when they are joined together, it has an oval inner surface with a maximum radius of curvature than the lowest radius of curvature. Deviated from an elliptical shape, it is also necessary to mount the gas compressor support and the built-in motor, and possibly the case where the hood is assembled. The stamina is consistent and will degrade. Sound that can be radiated And in any shape, size, any size of the casing, it has an audible natural resonance frequency greater than 3500 Hz.

1. To place a leak-proof gas compressor for use in refrigeration systems. Motorized And gas compressor They are assembled and flexible packed and secured within a gas compressor hood, a type that forms two hoods and two them together. And the gas compressor jacket is fixed in the refrigeration unit.The improved gas compressor jacket is made of sheet metal to give the inner surface an elliptical shape. And diverted from that shape where it is needed to support the internal gas compressor and to seal the engine hood together. When applied together, it forms an elliptical inner surface with different curves in each intersecting plane, and has a specified minimum distance between the inner surface of the machine jacket. And a motor-compressor unit Contained gas With a predetermined minimum clearance between the outside of the casing and the parts of the cooling unit that are nearby and within the predetermined distance range. Consecutive bends with the greatest radius of curvature The smallest laba differs in about 1 rank of size. This will make the machine jacket uniform stiffness and reduce the noise level emitted. The inner surface of the casing is symmetrical around three axes. Which are perpendicular to each other U, V and W and where the inner surface of the machine jacket may be described in general equation: 528S to the power of 6 U to the power of 2 + 19.6S to the power of 4 U to the power of 4 + 0.558U raised. Power 8 + 1322S raised to 6 V power 2 + 709S raised to 6 W power 2 + 0.990S raised to 2 W power 6 + 0.463W raised to 8 when S is a size factor. 2. Improvement according to claim 1, where the machine jacket has All audible natural resonance frequencies above 350hz. 3. Improvement according to claim 1 where the maximum distance in the U and W directions is approximately 7.62 cm, while the maximum distance in the direction v is approximately 6.99 cm. 4. Improvement according to claim 1, where the radius equivalent value The curvature of the axes that intersect the inner surface of the casing is approximately 14.99, 19.81 and 20.57 cm, respectively. 5. Improvement according to claim 1 where the radius of curvature of The inner surface is generally no more than about 33 cm. 6. Improvement according to claim 1, where the radius of curvature of The inner surface is generally more than about 2.54 cm. 7.How to reduce the noise level emitted by the compression jacket The air-tightening gas consists of the following steps: determining the required minimum clearance between the inside of the jacket. Cover the machine and the gas compressor set inside. Finding the required minimum distance between the outside of the jacket. Cover the machine and the environment near the gas compressor and shape the engine hood according to the above requirements. To achieve maximum curvature And to prevent the curvature Discrete The machine jacket is shaped to have a collar. Battle Which when used together to pack the machine Pressed gauze will have an oval inner surface. Which is explained by the car coordinates Thesian follows 528X2 + 19.6X4 + 0.558X8 + 1322Y2 + 0.990Z6 + 0.463Z8 = 10,000 8. Method according to Claim 7, where the body shape procedure Acted under the requirement that the proportion between the maximum value of the radius Curvature to the minimum value of the radius of curvature of the inner surface of A machine jacket worth about 10 9. Method for Claim 7, which includes additional steps in Limiting the value of the radius of curvature of the inner bins of the cloak The machine is less than about 33 cm 1 0. Method for Claim 7, which includes additional steps in Limiting the value of the radius of curvature of the inner surface of the jacket The machine is higher than approximately 2.54 cm (10 claims, 2 pages, 7 pictures)
