Description

Technical Field

[0001] The invention relates to the technical field of evaporator noise reduction, and in particular to a capillary expansion silent evaporation device. Background Art

[0002] The existing silent evaporation device adopts advanced refrigeration technology and realizes the transformation of refrigerant from liquid to gas through the coordinated work of core components such as evaporator, compressor, condenser and expansion valve (capillary tube). During the refrigerant evaporation refrigeration process, the device effectively reduces the abnormal noise generated by the flow of refrigerant through specific structure and design, providing a quiet use environment.

[0003] However, the prior art still has the following defects when used specifically: 1. In the existing refrigeration process, the compressor compresses and liquefies the intermediate substance (generally Freon) to release heat, and then evaporates and absorbs heat through the evaporation end, eventually forming a circulation system. However, the conversion of the refrigerant between liquid and gas involves a large amount of latent heat, that is, the heat absorbed or released during the phase change process, and the absorption and release of latent heat takes time, which will cause the refrigerant's form conversion speed to be slow. In addition, during the refrigerant compression and liquefaction and evaporation heat absorption process, when heat is exchanged between the refrigerant and the external environment, the heat transfer speed is slow and the heat exchange efficiency is low, which leads to low form conversion efficiency. Especially in the evaporation heat absorption process, a large amount of heat needs to be absorbed to evaporate the refrigerant.

[0004] 2. When a high-pressure liquid medium enters a low-pressure area, the pressure in the liquid suddenly drops, causing the liquid to evaporate rapidly and form a large number of bubbles. As the bubbles expand, they eventually reach a critical point and burst. When the bubbles burst, there will be an instantaneous release of energy. This energy release will propagate in the form of sound waves to form noise. When the liquid is suddenly depressurized, the flow state will change from laminar flow to turbulent flow. Turbulence will produce additional energy loss, which will also manifest itself in the form of noise, thereby having a negative impact on the surrounding environment, especially in the room or workplace where the equipment is located. Noise can affect the health and work comfort of the staff.

[0005] In view of this, the present invention proposes a capillary expansion silent evaporation device to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a capillary expansion silent evaporation device to solve the technical problems raised in the above background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the present invention is: a capillary expansion silent evaporation device, comprising a shell, a compressor is installed inside the shell, a condenser is connected to the outside of the compressor, the condenser is connected to the expansion valve through a capillary tube, an evaporator is connected above the expansion valve, the evaporator is connected to the compressor, a circulation diversion mechanism is arranged on the side of the compressor away from the inner wall of the shell, and a layer-by-layer noise reduction mechanism is arranged on the outside of the expansion valve; the circulation diversion mechanism is used to accelerate the heat alternation inside the shell and accelerate the refrigeration efficiency; the layer-by-layer noise reduction mechanism is used to release the operating pressure of the expansion valve in a step-by-step manner to achieve noise reduction.

[0008] Furthermore, the circulation diversion mechanism is installed on the supply and delivery pipe inside the shell, and the end of the supply and delivery pipe away from the shell is connected to a separation bin, the inner wall of the separation bin is fixedly connected with a circular column, the upper surface of the circular column is fixedly connected with a swirl plate, the upper surface of the swirl plate is connected with an upper branch pipe, the lower surface of the separation bin is connected with a lower branch pipe, and the lower end of the lower branch pipe is connected with an arc shell.

[0009] Furthermore, the circular column is composed of a combination of a disc and a cylinder, the size of the disc in the circular column is equal to the inner wall size of the separation bin, a spacing layer is formed between the cylinder in the circular column and the separation bin, and the inner layer of the supply delivery pipe and the separation bin are filled with sound insulation cotton.

[0010] Furthermore, arc grooves are evenly formed on the surface of the swirl plate, and the radius of the swirl plate is equal to the radius of the cylinder in the annular column.

[0011] Furthermore, the arc surface shell is in an incomplete arc shape as a whole, the arc surface shell corresponds to the shell side wall which shrinks inwards, and a three-hole conveying row is installed at the center position of the arc surface shell.

[0012] Furthermore, the layer-by-layer noise reduction mechanism includes a buffer bin connected to the bottom of the expansion valve, the inner side wall of the buffer bin is evenly and symmetrically fixedly connected with a rectangular long plate, a buckle group is installed below the rectangular long plate, and a pressure relief cylinder is connected above the expansion valve, and a drainage group is evenly installed on the inner wall of the pressure relief cylinder.

[0013] Furthermore, one end of the buffer bin away from the expansion valve is connected to the capillary tube, and one end of the pressure release cylinder away from the expansion valve is connected to the evaporator.

[0014] Furthermore, the rectangular long plate is installed in an inclined manner as a whole, the buckle group is composed of a combination of a circular ring and a rectangular short plate as a whole, the rectangular short plate in the buckle group is installed in an inclined manner, and the rectangular long plate is parallel to the rectangular short plate in the buckle group.

[0015] Furthermore, the pressure relief cylinder is funnel-shaped as a whole, one end of the pressure relief cylinder close to the expansion valve is expanded, and the inner diameter of the end of the pressure relief cylinder close to the expansion valve is equal to the inner diameter of the buffer bin.

[0016] Furthermore, the drainage group is composed of a combination of six flexible gaskets, each of which is rotatably connected to the inner wall of the pressure release tube, and the ends of the flexible gaskets that are close to each other are located in the same vertical plane.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to improve the problem of refrigerant cycle efficiency in the prior art, the present device divides compressed air into high-temperature and low-temperature parts through a swirl plate structure, ensuring that the low-temperature gas acts on the inside of the equipment through the lower branch pipe, thereby providing a low-temperature environment for it. First, the low-temperature condensation environment helps to maintain the stability and efficiency of the refrigerant in the liquid state, thereby extending the life of the refrigerant cycle. Secondly, it can ensure that the refrigerant can quickly release heat during the condensation process, thereby accelerating the transformation of the gaseous state to the liquid state, thereby satisfying that the equipment can achieve the desired refrigeration effect in a shorter time, thereby saving energy and time.

[0018] Compared with the existing technology, this device significantly improves the thermal efficiency of the device and reduces energy loss by optimizing the heat transfer path and enhancing heat exchange. The separation and bidirectional utilization of high-temperature gas and low-temperature gas enable the device to more effectively utilize the energy of compressed air, thereby improving the efficiency of the overall system.

[0019] The design of the arc groove on the surface of the swirl plate allows the gas molecules to produce energy separation during the flow process, and flow in a spiral along the inner wall of the upper branch pipe. This flow mode optimizes the heat transfer path, making the heat transfer more uniform and efficient.

[0020] (2) The device adopts the design of the arc surface shell so that the high-temperature gas can effectively flow to both sides along its inner arc surface when passing through the three-hole conveying row. This gas flow from the inside to the outside not only achieves efficient alternating heat dissipation inside and outside the equipment and optimizes the energy consumption performance of the equipment, but also avoids the backflow of external air into the interior of the equipment, thereby reducing the possibility of impurities in the external air entering the interior of the equipment, reducing the interference of air flow on the temperature distribution inside the equipment, and thus improving the operating stability of the equipment.

[0021] (3) In order to improve the noise problem in the prior art, the present device achieves optimized control of fluid dynamics by adding a buffer tank structure, effectively slowing down the flow of liquid entering the expansion valve. Relying on the cooperation of the liquid impact in the buffer tank and the capillary deceleration mechanism, the laminar state of the liquid can be transitioned more smoothly, thereby reducing the additional energy loss and accompanying noise caused by liquid turbulence. The slowed liquid flow enables the expansion valve to handle the fluid more efficiently, reducing the energy loss caused by the sharp drop in the boiling point of the refrigerant due to the rapid decompression, thereby better controlling the liquid-to-gas process of the refrigerant and significantly reducing the bubble burst noise caused by the sudden decompression of the high-pressure liquid inside the device.

[0022] (4) In conjunction with the design of the above-mentioned buffer tank, a pressure relief cylinder is installed at the output end of the expansion valve. The end of the pressure relief cylinder close to the expansion valve is in an expanded form, which prevents the discharged medium from contacting the inner wall of the pressure relief cylinder in the first time, so that it diffuses itself first. In this way, the collision between the gas and liquid phases is effectively reduced, and a smoother expansion and diffusion process is achieved, thereby greatly reducing the noise generated by rapid decompression.

[0023] (5) The drainage group is composed of six flexible gaskets, and their ends that are close to each other are all located in the same vertical plane. This design allows the flexible gaskets in the drainage group to effectively guide the flow path of the medium when it flows inside the decompression tube, reducing the flow resistance. In addition, the flow rate of the medium is significantly accelerated in conjunction with the gradually contracting shape of the decompression tube. By reducing the flow resistance and accelerating the flow rate, the design of the drainage group effectively improves the drainage effect, allowing the medium to be drained and processed more effectively, thereby improving the stability and reliability of the device design.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that the above-mentioned compressor 11, condenser 12, expansion valve 13, evaporator 14, capillary tube 15 and other devices can adopt commercially available related products. The structure and working principle of these products belong to the existing technology and will not be repeated here.

[0037] Example 1: Please refer to Figure 1 to Figure 2 As shown, a capillary expansion silent evaporation device comprises a shell 1, a compressor 11 is installed inside the shell 1, a condenser 12 is connected to the outside of the compressor 11, the condenser 12 is connected to the expansion valve 13 through a capillary tube 15, an evaporator 14 is connected above the expansion valve 13, the evaporator 14 is connected to the compressor 11, a circulation diversion mechanism 2 is arranged on the side of the compressor 11 away from the inner wall of the shell 1, and a layer-by-layer noise reduction mechanism 3 is arranged outside the expansion valve 13; the shell 1 can be designed accordingly according to the situation in which the device is used in an ice maker or a refrigerator.

[0038] Please refer to Figures 2 to 6As shown, the circulation diversion mechanism 2 includes a supply and delivery pipe 21 installed inside the shell 1, and the end of the supply and delivery pipe 21 away from the shell 1 is connected to the separation bin 22, the inner wall of the separation bin 22 is fixedly connected with a circular column 23, the upper surface of the circular column 23 is fixedly connected with a swirl plate 24, the upper surface of the swirl plate 24 is connected with an upper branch pipe 25, the lower surface of the separation bin 22 is connected with a lower branch pipe 26, and the lower end of the lower branch pipe 26 is connected with an arc shell 27.

[0039] It should be noted that the annular column 23 is composed of a combination of a disc and a cylinder. The size of the disc in the annular column 23 is equal to the inner wall size of the separation bin 22. A spacing layer is formed between the cylinder in the annular column 23 and the separation bin 22. The inner interlayer of the supply and delivery pipe 21 and the separation bin 22 are filled with sound insulation cotton. The surface of the swirl plate 24 is evenly provided with arc grooves, and the radius size of the swirl plate 24 is equal to the radius size of the cylinder in the annular column 23.

[0040] Specifically, Figure 3 and Figure 4 As shown, when the whole equipment starts to run, the compressor at the end of the supply delivery pipe 21 will continuously input compressed air into the separation chamber 22. Since the annular column 23 is composed of a combination of a disc and a cylinder, and the size of the disc in the annular column 23 is equal to the inner wall size of the separation chamber 22, and a spacing layer is formed between the cylinder in the annular column 23 and the separation chamber 22, the flowing compressed air can only flow along the arc groove opened on the surface of the swirl plate 24. At this time, the gas will produce a certain rotational motion in the arc groove under the position restriction of the swirl plate 24 and the action of gas inertia. This rotational motion will cause the gas to flow in a spiral shape, and then the gas will form a high-speed rotating vortex inside the upper branch pipe 25. In this process, due to the action of centrifugal force, the gas will be divided into two parts. The heavier gas molecules are pushed to the outside of the vortex, while the lighter gas molecules gather toward the center, and the air molecules Due to the energy separation caused by friction and collision, the temperature of the air flow in the center drops sharply. At this time, the low-temperature gas in the center will move in the opposite direction along the inner wall of the upper branch pipe 25, enter the lower branch pipe 26 through the inside of the circular column 23, and then flow out from the curved shell 27 at the lower end of the lower branch pipe 26. The temperature of the outer air flow increases and the speed decreases, and it is pushed to the outer wall and flows out from the curved shell 27 above the upper branch pipe 25. Through this two-way diversion method, the low-temperature gas is ensured to act on the inside of the equipment through the lower branch pipe 26, thereby providing it with a low-temperature environment. First, the low-temperature condensation environment helps to maintain the stability and efficiency of the refrigerant in the liquid state, thereby extending the life of the refrigerant cycle. Secondly, it can ensure that the refrigerant can quickly release heat during the condensation process, thereby accelerating the transformation from gas to liquid, thereby satisfying that the equipment can achieve the required refrigeration effect in a shorter time, thereby saving energy and time.

[0041] It should be noted that the arc surface shell 27 is in an incomplete arc shape as a whole, the arc surface shell 27 is contracted inwardly corresponding to the side wall of the shell 1, and a three-hole conveying row is installed at the center position of the arc surface shell 27.

[0042] Specifically, the design of the arc shell 27 allows the high-temperature gas and the low-temperature gas to flow effectively to both sides along the inner arc surface when passing through the three-hole conveying row. This gas flow from the inside to the outside not only achieves efficient alternating heat dissipation of the heat inside and outside the equipment and optimizes the energy consumption performance of the equipment, but also avoids the backflow of external air into the interior of the shell 1, thereby reducing the possibility of impurities in the external air entering the interior of the shell 1, reducing the interference of air flow on the temperature distribution inside the equipment, and thus improving the operating stability of the equipment.

[0043] Example 2: Based on Example 1, please refer to Figures 7 to 10 As shown, the layer-by-layer noise reduction mechanism 3 includes a buffer bin 31 connected to the bottom of the expansion valve 13, the inner wall of the buffer bin 31 is evenly and symmetrically fixedly connected with a rectangular long plate 32, and a buckle group 33 is installed below the rectangular long plate 32. A pressure relief cylinder 34 is connected to the top of the expansion valve 13, and a drainage group 35 is evenly installed on the inner wall of the pressure relief cylinder 34.

[0044] It should be noted that the end of the buffer bin 31 away from the expansion valve 13 is connected to the capillary 15, the end of the pressure relief cylinder 34 away from the expansion valve 13 is connected to the evaporator 14, the rectangular long plate 32 is installed in an inclined manner as a whole, the buckle group 33 is composed of a combination of a circular ring and a rectangular short plate, the rectangular short plate in the buckle group 33 is installed in an inclined manner, and the rectangular long plate 32 and the rectangular short plate in the buckle group 33 are parallel.

[0045] Specifically, the high-temperature and high-pressure refrigerant gas releases heat in the condenser 12 and turns into a high-pressure liquid. Before the liquid enters the expansion valve 13, it will first enter the buffer bin 31. At this time, a part of the liquid flows straightly between the circular rings in the buckle group 33. Since the rectangular short plates and the rectangular long plates 32 in the buckle group 33 are distributed in a parallel and inclined form, the other part of the liquid will flow between the rectangular short plates and the rectangular long plates 32 along their inclined side walls in the form of curved corners. When the liquid flowing in a curved direction subsequently merges into the straight-flowing liquid, it will cause impact reflux on the straight-flowing liquid, thereby reducing the flow rate of the liquid. By relying on the cooperation of the liquid impact and deceleration mechanism in the buffer bin 31, the laminar state of the liquid can be transitioned more smoothly, thereby reducing the additional energy loss and accompanying noise caused by liquid turbulence, and the slowed liquid flow rate enables the expansion valve 13 to process the fluid more efficiently, thereby better controlling the liquid-to-gas process of the refrigerant, and significantly reducing the bubble burst noise caused by the sudden decompression of the high-pressure liquid inside the device.

[0046] It should be noted that the pressure relief cylinder 34 is funnel-shaped as a whole, and the end of the pressure relief cylinder 34 close to the expansion valve 13 is in an expanded form, and the inner diameter of the end of the pressure relief cylinder 34 close to the expansion valve 13 is equal to the inner diameter of the buffer chamber 31, and the drainage group 35 is composed of six flexible gaskets, and the flexible gaskets are rotatably connected to the inner wall of the pressure relief cylinder 34, and the ends of the flexible gaskets in the pressure relief cylinder 34 that are close to each other are all located in the same vertical plane.

[0047] Specifically, after the liquid is discharged from the expansion valve 13, it will become a gas-liquid mixed two-phase object, namely, the medium. Since the end of the pressure release cylinder 34 close to the expansion valve 13 is in an expanded form and the overall size is larger than the output end of the expansion valve 13, when the medium is discharged from the expansion valve 13, it cannot contact the inner wall of the pressure release cylinder 34 in the first time, so it diffuses itself first. In this way, the collision between the gas and liquid phases is effectively reduced, and a more gentle expansion and diffusion process is achieved, thereby greatly reducing the noise generated by the rapid decompression. In addition, since the pressure release cylinder 34 is rotatably connected with the flexible gasket, and the ends of the flexible gaskets close to each other are located in the same vertical plane, when the medium flows inside the pressure release cylinder 34, the flexible gasket in the drainage group 35 can effectively guide its flow path and reduce the flow resistance. In addition, the flow rate of the medium is significantly accelerated in conjunction with the gradually contracting shape of the pressure release cylinder 34. By reducing the flow resistance and accelerating the flow rate, the drainage effect is effectively improved by relying on the design of the drainage group 35, so that the medium can be more effectively drained and processed, thereby improving the stability and reliability of the device design.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
