[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as upper, lower, left, right, front, rear, inner, and outer that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0024] The refrigeration system provided by the present utility model can make the layout of the refrigeration system more compact, avoid the problem of messy pipelines in the refrigeration system, and effectively improve the space utilization rate of the refrigeration pipeline 5.

[0025] In a specific embodiment of the present utility model, as Figure 1 shown, the refrigeration system includes a compressor 4, a condensing assembly 3, a throttling member 6, an evaporator 7, and a refrigeration pipeline 5. The refrigeration pipeline 5 includes a first connecting pipe 51, a second connecting pipe 52, and a third connecting pipe 53. The outlet of the compressor 4 is connected to the inlet of the condensing pipe 332 of the condensing assembly 3 through the first connecting pipe 51. The outlet of the condensing pipe 332 of the condensing assembly 3 is connected to the inlet of the throttling member 6. The outlet of the throttling member 6 is connected to the inlet of the evaporator 7 through the second connecting pipe 52. The outlet of the evaporator 7 is connected to the inlet of the compressor 4 through the third connecting pipe 53. Among them, the second connecting pipe 52 is wound around the surface of the third connecting pipe 53.

[0026] The refrigeration system provided in this embodiment connects the compressor 4, the condensing assembly 3, the throttling member 6, and the evaporator 7 in sequence through the refrigeration pipeline 5 to form a refrigeration cycle for the refrigeration system. When arranging the refrigeration pipeline 5, with the length of the second connecting pipe 52 fixed, by winding the second connecting pipe 52 around the surface of the third connecting pipe 53 and integrating the second connecting pipe 52 and the third connecting pipe into one space, the overall volume occupied by the refrigeration pipeline 5 in the space can be effectively reduced, so that the layout of the refrigeration system can be more compact, avoiding the problem of messy pipelines in the refrigeration system, and effectively improving the space utilization rate of the refrigeration pipeline 5.

[0027] In addition, when the refrigeration system is working, vibration noise may be generated in the refrigeration pipeline 5 due to fluid flow or other vibration reasons. By winding the second connecting pipe 52 around the third connecting pipe 53, the overall vibration resistance of the second connecting pipe 52 and the third connecting pipe 53 can also be enhanced, thereby reducing the noise generated by the vibration of the refrigeration pipeline 5 during operation.

[0028] In this embodiment, as Figure 1As shown, the second connecting pipe 52 is spirally wound around the third connecting pipe 53. The winding radius of the second connecting pipe 52 is greater than the diameter of the third connecting pipe 53, and the winding pitch of the second connecting pipe 52 is greater than the diameter of the second connecting pipe 52. Further, when the second connecting pipe 52 is wound around the third connecting pipe 53, the second connecting pipe 52 can maintain a certain radius of curvature at the bending position, ensuring a smooth transition at the bending position, thereby reducing the turbulence of the refrigerant fluid at the bending position of the second connecting pipe 52, improving the stability of the fluid flow in the second connecting pipe 52, and ensuring that the fluid is not blocked by the bending position.

[0029] It should be noted here that the winding pitch and winding radius of the second connecting pipe 52 can be assisted by fluid dynamics software or other simulation tools for analysis to predict the fluid flow and pressure distribution in the pipeline and ensure the stability of the fluid flow.

[0030] Furthermore, since the low-temperature and low-pressure refrigerant liquid flows in the second connecting pipe 52 and the low-temperature and low-pressure refrigerant gas flows in the third connecting pipe 53, there may be a certain temperature difference between the two refrigerant media. To prevent the refrigerant liquid at the second connecting pipe 52 from exchanging heat with the refrigerant gas in the third connecting pipe 53 and reducing the cooling capacity of the refrigerant liquid for the evaporator 7, a heat insulation member is provided on the surface of the third connecting pipe 53, and the second connecting pipe 52 is wound around the heat insulation member to use the heat insulation member to prevent the second connecting pipe 52 from contacting the third connecting pipe 53, so that the refrigerant liquid in the second connecting pipe 52 does not exchange heat with the refrigerant gas in the third connecting pipe 53, thereby ensuring that the cooling capacity of the refrigerant liquid for the evaporator 7 is not affected by the temperature of the refrigerant gas in the third connecting pipe 53 and ensuring the refrigeration efficiency of the refrigerant for the evaporator 7.

[0031] Preferably, the heat insulation member is made of rubber heat insulation material to insulate heat while buffering the second connecting pipe 52 and preventing deformation of the second connecting pipe 52 or the third connecting pipe 53 after winding.

[0032] Among them, such as Figure 1 and Figure 3As shown, the second connecting pipe 52 is a capillary tube. The capillary tube and the throttling member 6 together play a role in throttling and pressure reduction in the refrigeration system to ensure that the refrigerant enters the evaporator 7 in a low-temperature and low-pressure state. The throttling member 6 is preferably an expansion valve. The cross-sectional area of the inner wall surface at the outlet section of the throttling member 6 gradually decreases along the flow direction of the fluid, so as to facilitate the connection between the capillary tube and the outlet section of the throttling member 6. Moreover, since the cross-sectional area of the inner wall surface of the outlet section of the throttling member 6 gradually decreases, when the refrigerant liquid flows through the outlet section of the throttling member 6, the flow rate of the refrigerant liquid gradually increases along the flow direction of the fluid, and a negative pressure is formed at the capillary tube inlet, so as to further increase the flow rate of the refrigerant liquid in the capillary tube, thereby reducing the residence time of the refrigerant liquid in the capillary tube, further avoiding heat exchange between the refrigerant liquid and other media, and further ensuring the refrigeration efficiency of the evaporator 7.

[0033] In this embodiment, as Figure 1 and Figure 2 shown, the evaporator 7 is provided with an evaporation pipeline 71. The inlet of the evaporation pipeline 71 is connected to the outlet of the second connecting pipe 52, and the outlet of the evaporation pipeline 71 is connected to the third connecting pipe 53. The diameter of the evaporation pipeline 71 is smaller than that of the second connecting pipe 52, and the cross-sectional area of the inlet section of the evaporation pipeline 71 gradually increases along the flow direction of the fluid. Then, when the refrigerant liquid flows through the inlet section of the evaporation pipeline 71, the flow rate of the refrigerant liquid gradually decreases along the flow direction of the fluid, so as to lengthen the residence time of the refrigerant liquid in the evaporation pipeline 71, ensuring that the refrigerant liquid can fully absorb heat and vaporize in the evaporation pipeline 71, and forming a low-temperature and low-pressure refrigerant gas, thereby ensuring the refrigeration effect of the evaporator 7 on the heat exchange medium.

[0034] Exemplarily, the evaporator 7 is arranged in the ice-making cavity of the ice-cold drink machine. The evaporation pipeline 71 is wound around the inner wall surface of the evaporator 7. After the refrigerant liquid in the evaporation pipeline 71 conducts heat through the wall surface of the evaporator 7, it exchanges heat with liquid heat exchange media such as water in the refrigeration cavity. The low-temperature and low-pressure refrigerant liquid vaporizes after fully absorbing heat, forming a low-temperature and low-pressure refrigerant gas, and is output from the third connecting pipe 53 at the outlet of the evaporation pipeline 71, and converts liquid heat exchange media such as water into solid media to realize the ice-making function of the ice-cold drink machine.

[0035] In this embodiment, after the low-temperature and low-pressure refrigerant gas is input into the compressor 4 from the evaporator 7, it is transformed into a high-temperature and high-pressure refrigerant gas under the action of the compressor 4. Subsequently, the refrigerant gas is output from the compressor 4 through the first connecting pipe 51. To shorten the transmission time of the refrigerant gas between the compressor 4 and the condensing assembly 3, the cross-sectional area of the outlet section of the first connecting pipe 51 gradually decreases along the flow direction of the fluid, so as to form a negative pressure area at the outlet section of the first connecting pipe 51, thereby increasing the flow rate of the refrigerant gas input into the condensing assembly 3 and realizing shortening the transmission time of the refrigerant gas in the first connecting pipe 51.

[0036] In this embodiment, the high-temperature and high-pressure refrigerant gas is condensed by the condensing assembly 3 to form a liquid refrigerant, and then the liquid refrigerant is input into the throttling member 6 for throttling and pressure reduction. To prevent impurities in the refrigerant liquid from damaging the throttling member 6, a filter is provided between the inlet of the throttling member 6 and the outlet of the condensing pipe 332 of the condensing assembly 3 to intercept and remove the impurities in the refrigerant liquid by means of the filter, ensuring that the refrigerant liquid can be in a relatively clean state before flowing into the throttling member 6, thereby protecting the throttling member 6 from damage by impurities.

[0037] In this embodiment, as Figure 1 , Figures 4 to 6 shown, the refrigeration system further includes a base 1, the base 1 is provided with a mounting bracket 2, the condensing assembly 3 is mounted on the mounting bracket 2, and the mounting bracket 2 is used to suspend the condensing assembly 3 on the base 1 to increase the contact area between the overall condenser and the flowing air, improve the heat exchange efficiency between the condenser and the air, and thus improve the condensing effect of the condenser.

[0038] Specifically, as Figure 4 and Figure 6 shown, at least one set of first connection groups are formed on the mounting bracket 2, the first connection group includes a clamping groove 211 and two threaded holes 212, and the two threaded holes 212 are respectively distributed on both sides of the clamping groove 211; at the same time, at least one set of second connection groups are formed on the condensing assembly 3, the second connection group includes a buckle 311 and two connection holes 312, and the two connection holes 312 are respectively distributed on both sides of the clamping groove 211, the buckle 311 is correspondingly clamped with the clamping groove 211, and each connection hole 312 is threadedly connected to the corresponding threaded hole 212 through a connection bolt.

[0039] Furthermore, when installing the condensing assembly 3 on the mounting bracket 2, the positioning effect of the buckle 311 and the clamping groove 211 can be used to determine the installation position of the condensing assembly 3 on the mounting bracket 2, and then the condensing assembly 3 is locked and fixed on the mounting bracket 2 through the connection bolt, so as to improve the installation convenience of the condensing assembly 3 on the mounting bracket 2 while ensuring the connection stability between the condensing assembly 3 and the mounting bracket 2.

[0040] Further, as Figure 6 shown, a support plate 22 is formed on the side wall of the mounting bracket 2, the support plate 22 is located below the first connection group, the condensing assembly 3 is provided with an outer extension plate 32, the outer extension plate 32 faces the mounting bracket 2, the second connection group is formed on the outer extension plate 32, and the support plate 22 abuts against the lower part of the outer extension plate 32.

[0041] It can be understood that the condensation assembly 3 is connected to the mounting bracket 2 through the outer extension plate 32. The outer extension plate 32 is supported by the support plate 22. In addition to acting on the mounting bracket 2 through the connection structure, the gravity of the condensation assembly 3 can also act on the mounting bracket 2 through the support plate 22, thus preventing the gravity of the condensation assembly 3 from concentrating on the connection structure and causing deformation or damage to the connection structure, thereby improving the support and load-bearing capacity of the mounting bracket 2 for the condensation assembly and effectively ensuring the stability and reliability of the connection between the condensation assembly 3 and the mounting bracket 2.

[0042] Wherein, when the condensation assembly 3 and the mounting bracket 2 are connected through the buckle 311 and the clamping groove 211, a first spacing distance is formed between the clamping groove 211 and the base 1, and a second spacing distance is formed between the clamping groove 211 and the bottom of the condensation assembly 3, and the first spacing distance is greater than the second spacing distance, so as to ensure that a gap can be formed between the bottom of the condensation assembly 3 and the base 1 after the condensation assembly 3 is installed on the mounting bracket 2, ensuring that the condensation assembly 3 is suspended and installed between the base 1 and the mounting bracket 2.

[0043] Wherein, as Figure 4 and Figure 5 shown, the condensation assembly 3 includes a condenser body 33 and an air-cooling part 34. The second connecting piece is arranged on the condenser body 33 to connect the condenser body 33 to the mounting bracket 2. The air-cooling part 34 is installed on one side of the condenser body 33 facing the mounting bracket 2. The air-cooling part 34 forms an air outlet area, and the condenser body 33 is located in the air outlet area. Furthermore, the air-cooling part 34 can be operated to provide a flowing cooling air flow for the condenser body 33, and the cooling air flow is used to exchange heat with the refrigerant gas in the condenser body 33, increasing the heat exchange efficiency between the cooling air flow and the refrigerant gas in the condenser body 33 and improving the condensation efficiency of the condenser body 33. The air-cooling part 34 is preferably a cooling fan.

[0044] The condenser body 33 includes a mounting plate 331, a condensation pipe 332 and a plurality of heat dissipation fins 333. The mounting plate 331 is detachably connected to the mounting bracket 2. The plurality of heat dissipation fins 333 are arranged at intervals on the side of the mounting plate 331 facing away from the mounting bracket 2 in a direction parallel to the base 1. The condensation pipe 332 is inserted into the plurality of heat dissipation fins 333 in a serpentine shape. When the flowing air flows through the condenser body 33, due to the obstruction of the heat dissipation fins 333, more turbulent flows and eddy currents are formed in the flowing air, thereby increasing the contact area between the condensation pipe 332 and the flowing air while enhancing the convective heat transfer between the air and the condenser, enabling the flowing air to exchange heat with the condensation pipe 332 more fully and further improving the condensation efficiency of the condenser body 33.

[0045] And for the convenience of the installation between the air-cooling part 34 and the condenser body 33, as Figure 4 and Figure 5As shown in the figure, on the side of the mounting plate 331 facing the air-cooling component 34, there are positioning posts 334 and at least one mounting hole 335. On the side of the air-cooling component 34 facing the mounting plate 331, there are a plurality of positioning holes 341. Among them, the positioning posts 334 are adapted to be inserted into a part of the positioning holes 341, and the mounting holes 335 and another part of the positioning holes 341 are detachably connected by fasteners. Preferably, the fasteners are studs or bolts. Through the cooperation between the positioning holes 341 and the positioning posts 334, the accurate positioning of the air-cooling component 34 on the mounting plate 331 can be ensured, effectively reducing the human error during the installation process, thereby improving the installation quality between the air-cooling component 34 and the mounting plate 331.

[0046] Furthermore, as Figure 1 shown, the base 1 is further provided with a support base 41. A gap is formed between the support base 41 and the base 1, and the compressor 4 is installed on the support base 41. Furthermore, the vibration generated when the compressor 4 works can also be buffered by the support base 41, which can avoid the resonance among the condensing component 3, the compressor 4 and the base 1 when the refrigeration system works, and thus reduce the noise generated by the vibration when the refrigeration system works.

[0047] Correspondingly, the present utility model further provides an ice cream machine, which includes a refrigeration cavity, a control system and the refrigeration system described in any one of the above embodiments. The evaporator 7 is arranged in the refrigeration cavity, and the compressor 4, the condensing component 3 and the evaporator 7 are all connected to the control system. Since the ice cream machine includes the above refrigeration system, the ice cream machine also has all the beneficial effects of the above refrigeration system, which will not be elaborated here.

[0048] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
