[0001] This application relates to the field of refrigeration technology, and in particular to an evaporative refrigeration device and an ice-making apparatus. Background Technology

[0002] Ice makers, as devices that quickly produce ice, can be used in industrial settings as well as in homes, small shops, offices, and other places to bring convenience to users. An ice maker typically includes an evaporator, a condenser, and a compressor. The refrigerant circulates between the compressor, condenser, and evaporator to produce ice. The evaporator is often connected to a capillary tube through a connection hole to lower the temperature of the refrigerant. During the evaporative refrigeration process, the evaporator is prone to freezing or frosting, resulting in poor ice-making effect and low ice-making efficiency. Utility Model Content

[0003] In view of this, embodiments of this application provide an evaporative refrigeration device and an ice-making apparatus to solve the above-mentioned technical problems.

[0004] In a first aspect, embodiments of this application provide an evaporative refrigeration device applied to an ice-making apparatus equipped with a compressor and a condenser. The evaporative refrigeration device includes an evaporator tube, a connector, a first pipe, and a second pipe. The evaporator tube has an inlet port, and the connector is connected to the inlet port. The connector has a first channel and a second channel spaced apart from each other. One end of the first channel is connected to the inlet port, and the other end is connected to the outside. One end of the second channel is connected to the inlet port, and the other end is connected to the outside. The first pipe passes through the first channel, with one end connected to the evaporator tube via the inlet port, and the other end connected to the condenser for transmitting refrigerant. The second pipe passes through the second channel, with one end connected to the evaporator tube via the inlet port, and the other end connected to the compressor for transmitting heat.

[0005] In some embodiments, the first channel extends in a straight line, and the first conduit is a capillary.

[0006] In some embodiments, the inner diameter of the first channel is smaller than the inner diameter of the second channel, the outer peripheral wall of the first pipe is in contact with the inner peripheral wall of the first channel, and the inner diameter of the first pipe is smaller than the inner diameter of the second pipe.

[0007] In some implementations, the first channel and the second channel are parallel.

[0008] In some embodiments, the connector includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence. The second connecting segment is connected between the first connecting segment and the third connecting segment. The first connecting segment is plugged into the refrigerant input terminal. A first channel passes through the third connecting segment, and a first pipe passes through the first connecting segment, the second connecting segment, and the third connecting segment in sequence. A second channel passes through the third connecting segment, and a second pipe is inserted into the third connecting segment.

[0009] In some embodiments, the size of the second connecting segment connected to one end of the first connecting segment is smaller than the size of the second connecting segment connected to one end of the third connecting segment.

[0010] In some embodiments, the first pipe protrudes from the end of the first connecting section away from the third connecting section and is inserted into the evaporator tube.

[0011] In some embodiments, the evaporative refrigeration device further includes a control valve, which is installed on the second pipe and is used to control the input amount of the heat medium.

[0012] Secondly, embodiments of this application provide an ice-making device, which includes an evaporative refrigeration device, a compressor, and a condenser as described in any embodiment.

[0013] In some embodiments, the ice-making device further includes an ice-making chamber, with an evaporation tube at least partially surrounding the outer periphery of the ice-making chamber.

[0014] Compared to existing technologies, this application provides an evaporative refrigeration device, which includes an evaporator, a connector, a first pipe, and a second pipe. Both the first and second pipes are connected to the evaporator via the connector. The first pipe carries refrigerant to ensure the evaporator's cooling function, while the second pipe carries heat to the evaporator to prevent overcooling and subsequent icing or frost formation. Specifically, the heat carries a large amount of heat energy, which, through heat conduction, raises the temperature of the evaporator, preventing water vapor in the air from condensing into ice or frost on its surface, thus ensuring the evaporator's cooling efficiency and effect. Furthermore, the connector, as a connecting component, integrates the first pipe, the second pipe, and the evaporator within a single connector by providing spaced-apart first and second channels. This not only reduces external connecting components and effectively lowers piping complexity but also improves the overall compactness and reliability of the device. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 This application provides an evaporative refrigeration device 100, which includes an evaporator tube 10, a connector 20, a first pipe 30, and a second pipe 40. The evaporative refrigeration device 100 is applied to an ice-making device 200 to cool the ice-making device 200, thereby maintaining the ice-making device 200 in a low-temperature environment. Specifically, liquid refrigerant evaporates and transforms into gaseous refrigerant in the evaporative refrigeration device 100. This phase change process absorbs a large amount of heat, causing the temperature of the ice-making device 200 to drop rapidly.

[0026] Please see Figures 1 to 3 The evaporative refrigeration device 100 provided in this application can be applied to an ice-making device 200. The ice-making device 200 may include a housing 201, which forms the external structure of the ice-making device 200 and is used to install components. The components may include the aforementioned evaporative refrigeration device 100. The housing 201 also serves to support the ice-making device 200 in its place of use, such as on the ground, a table, or other support platform. The components may also include a compressor 202, a condenser 203, and piping. The piping is used to transport refrigerant. The compressor 202 and the condenser 203 are connected by piping. The condenser 203 is connected to the evaporator pipe 10 via a first pipe 30. The evaporator pipe 10 is connected to the compressor 202 via piping to form a refrigerant circulation.

[0027] Specifically, the low-temperature, low-pressure gaseous refrigerant is pressurized in the compressor 202 to form a high-temperature, high-pressure gaseous refrigerant. This pressurized gaseous refrigerant then enters the condenser 203 through the piping, where it exchanges heat with air or condensate, condensing to form a high-pressure liquid refrigerant. When the high-pressure liquid refrigerant enters the evaporator 10 through the first pipe 30, the pressure drops sharply due to the sudden decrease in the cross-sectional area of ​​the first pipe 30 relative to the condenser 203, causing some of the refrigerant to vaporize instantly, forming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant evaporates and absorbs heat in the evaporator 10, forming a low-temperature, low-pressure gaseous refrigerant, which then flows back to the compressor 202 through the piping, completing one refrigerant cycle.

[0028] In this embodiment, the compressor 202 is also connected to the evaporator tube 10 via the second pipe 40, so that the hot gas generated by the compressor 202 during the pressurization process can enter the evaporator tube 10 through the second pipe 40, which can prevent the evaporator tube 10 from overfreezing and improve the cooling effect and cooling reliability of the ice-making equipment 200. In addition, by using the heat generated by the compressor 202 during the pressurization process to heat the evaporator tube 10, no additional heating device is required, which can save energy and reduce operating costs.

[0029] This embodiment does not limit the specific form of the ice-making device 200. For example, the ice-making device 200 can be a refrigerator, air conditioner, ice maker, ice extruder, etc. For ease of explanation, in this embodiment, the ice-making device 200 can be an ice extruder. Specifically, the ice-making device 200 may include a pushing assembly 210, which has an ice-making chamber 2101 for containing liquid water. The evaporative cooling device 100 is connected to the outer periphery of the pushing assembly 210 to exchange heat with the liquid water in the ice-making chamber 2101. Specifically, in this embodiment, the evaporator tube 10 at least partially surrounds the outer periphery of the ice-making chamber 2101 to increase the contact area, so that the refrigerant in the evaporator tube 10 can more fully absorb the heat from the liquid water in the ice-making chamber 2101, thereby accelerating the cooling process and improving ice-making efficiency.

[0030] The pushing component 210 is also provided with multiple ice outlet holes 2102, which are respectively connected to the ice-making chamber 2101. The ice-making chamber 2101 is connected to the outside through the multiple ice outlet holes 2102. The pushing component 210 may also include a pushing member 2103, which is movably disposed in the ice-making chamber 2101. When the ice-making device 200 is in operation, liquid water gradually condenses to form crushed ice or an ice-water mixture. The pushing member 2103 is used to push the crushed ice in the ice-making chamber 2101 and push the crushed ice toward the multiple ice outlet holes 2102, which can prevent the crushed ice from adhering to the inner wall of the ice-making chamber 2101. Meanwhile, the pusher 2103 can also squeeze the ice to move the ice out of the ice-making chamber 2101 through multiple ice outlet holes 2102. During this process, the ice is squeezed by the pusher 2103 and gradually compacted by mutual compression with the hole walls of the ice outlet holes 2102. The ice gradually solidifies, so that the ice that has been squeezed and moved out of the ice-making chamber 2101 forms ice blocks.

[0031] The ice-making device 200 may also include an extruder 2104, which is connected to the pusher assembly 210. Part of the structure of the extruder 2104 is spaced apart from a plurality of ice outlet holes 2102 to define an ice-making space 2105, which is the space between the extruder 2104 and the pusher assembly 210. The extruder 2104 is used to contact the ice block that is removed from the ice-making chamber 2101. In actual application scenarios, crushed ice is extruded by the pusher 2103 and removed from the ice-making chamber 2101 to form an ice block. As the pusher 2103 continues to extrude ice, more crushed ice is removed from the ice-making chamber 2101 through the ice outlet hole 2102. The size of the ice block corresponding to the ice outlet hole 2102 (the size of the ice block in the axial direction of its corresponding ice outlet hole 2102) gradually increases. The end of the ice block away from the ice outlet hole 2102 can move to contact the extruder 2104, and then continue to be extruded by the extruder 2104 until the ice block breaks.

[0032] In this embodiment, the ice-making device 200 further includes a toggle member 2106, which is movably connected to the pushing assembly 210. A portion of the toggle member 2106 is located on one side of the extruder 2104, outside the ice-making space 2105, to prevent the toggle member 2106 from affecting the extrusion of ice blocks by the extruder 2104. In practical applications, the toggle member 2106 can move broken ice blocks near multiple ice outlet holes 2102, causing them to leave the pushing assembly 210, preventing ice blocks from accumulating on the pushing assembly 210 and avoiding adhesion between ice blocks.

[0033] Please see Figure 1 and Figure 4 In one embodiment provided in this application, the evaporative refrigeration device 100 includes an evaporator 10, a connector 20, a first pipe 30, and a second pipe 40. The evaporator 10 has an inlet port 11, and the connector 20 is connected to the inlet port 11. The connector 20 has a first channel 21 and a second channel 22 spaced apart from each other. One end of the first channel 21 communicates with the inlet port 11, and the other end is used to communicate with the outside. One end of the second channel 22 communicates with the inlet port 11, and the other end is used to communicate with the outside. The first pipe 30 passes through the first channel 21, with one end connected to the evaporator 10 via the inlet port 11, and the other end connected to the condenser 203 for transmitting refrigerant. The second pipe 40 passes through the second channel 22, with one end connected to the evaporator 10 via the inlet port 11, and the other end connected to the compressor 202 for transmitting heat.

[0034] By setting up the first pipe 30, the second pipe 40, and the connector 20, it is ensured that the refrigerant can smoothly enter the evaporator tube 10 for cooling, while the heat medium can be transferred to the evaporator tube 10 through the second pipe 40 to prevent the evaporator tube 10 from overcooling and causing icing or frosting. Specifically, the heat medium carries a large amount of heat energy, which can raise the temperature of the evaporator tube 10 through heat conduction, thereby ensuring the cooling efficiency and cooling effect of the evaporator tube 10. In addition, the connector 20, as a connecting component, integrates the first pipe 30, the second pipe 40, and the evaporator tube 10 into a single connector by setting the first channel 21 and the second channel 22 spaced apart from each other. This not only reduces external connecting components and effectively reduces the complexity of the piping, but also improves the compactness and reliability of the overall device.

[0035] The following sections will introduce each component of the evaporative cooling device 100 and the specific structure of each component.

[0036] Please see Figure 1 and Figure 4 The evaporator tube 10 is the main structure of the evaporative refrigeration device 100, and it is used to contain the refrigerant. The refrigerant evaporates inside the evaporator tube 10, absorbing heat from the surrounding environment, thereby achieving a cooling or ice-making effect. The refrigerant can be water, Freon, propane, etc., and this embodiment does not limit this. In this embodiment, the material of the evaporator tube 10 can be a metal with a high thermal conductivity, such as stainless steel or copper alloy, which can accelerate heat transfer and improve cooling efficiency. The evaporator tube 10 may include a tube coil 12, which is wound around the outer periphery of the ice-making device 200 to increase the contact area with the ice-making device 200, thereby improving the cooling effect and cooling efficiency. The tube coil 12 can be an independent tube body wound around the outer periphery of the ice-making device 200, or the tube coil 12 can be directly welded to the outer periphery of the ice-making device 200, and this embodiment does not specifically limit this. In some embodiments, the surface of the evaporator tube 10 may be provided with a heat dissipation structure (not shown in the figure), such as fins, which can increase the heat exchange area, improve heat exchange efficiency, and thus enhance the cooling effect.

[0037] Please see Figures 4 to 6 In this embodiment, the evaporator tube 10 has an inlet port 11, which serves as the inlet for refrigerant to enter the evaporator tube 10. It is used to connect to the condenser 203 via a connector 20 and a first pipe 30 to ensure that the refrigerant can flow smoothly into the evaporator tube 10. Simultaneously, the inlet port 11 can also serve as the inlet for heat transfer medium to enter the evaporator tube 10. It is used to connect to the compressor 202 via a connector 20 and a second pipe 40 to ensure that the heat transfer medium can flow smoothly into the evaporator tube 10, thereby preventing over-freezing of the evaporator tube 10 and ensuring the cooling effect of the ice-making equipment 200.

[0038] Connector 20 is attached to the input port 11. As a T-connector, it can simultaneously connect the first pipe 30, the second pipe 40, and the evaporator 10, reducing the number of external connecting components, effectively lowering the piping complexity, and improving the overall compactness and reliability of the device. Specifically, connector 20 has a first channel 21 and a second channel 22 spaced apart from each other. One end of the first channel 21 is connected to the input port 11, and the other end is connected to the outside. One end of the second channel 22 is connected to the input port 11, and the other end is connected to the outside. When the evaporative refrigeration device 100 is working, the first pipe 30 is connected between the first channel 21 and the condenser 203 to supply refrigerant to the evaporator 10, and the second pipe 40 is connected between the second channel 22 and the compressor 202 to supply heat to the evaporator 10. That is, only one connector 20 is needed to supply refrigerant and heat to the evaporator 10, ensuring the refrigeration effect of the ice-making device 200 with a simpler piping connection.

[0039] In this embodiment, the first pipe 30 passes through the first channel 21 to transport refrigerant for cooling the evaporator tube 10. Specifically, one end of the first pipe 30 is connected to the evaporator tube 10 through the input port 11, and the other end is connected to the condenser 203. The material of the first pipe 30 can be a metal with a high thermal conductivity, such as stainless steel or copper alloy. This embodiment does not impose specific limitations on the diameter of the first pipe 30, which can be set according to actual usage requirements. It is understood that when the diameter of the first pipe 30 is small, the throttling and pressure reduction effect of the refrigerant in the first pipe 30 is better, providing low-temperature and low-pressure refrigerant for the evaporation of the evaporator tube 10, thereby improving the evaporation efficiency of the refrigerant in the evaporator tube 10. As a specific example, the first pipe 30 can be a capillary tube, where the refrigerant generates greater flow resistance when passing through its narrow channel, causing the pressure and temperature of the high-pressure liquid refrigerant to drop rapidly as it passes through, achieving the effect of throttling and expansion.

[0040] In some embodiments, the evaporative refrigeration device 100 may further include a solenoid valve (not shown in the figure), which is disposed on the first pipe 30. The solenoid valve is used to precisely regulate the flow of refrigerant entering the evaporator tube 10. Specifically, the ice-making device 200 also includes a controller (not shown in the figure) and a temperature sensor (not shown in the figure). The controller is electrically connected to the temperature sensor and the solenoid valve, respectively. The temperature sensor is disposed outside the ice-making chamber 2101 to obtain the temperature of the ice-making chamber 2101. When the temperature detected by the temperature sensor is outside the refrigeration temperature range, the controller controls the solenoid valve to adjust the opening and closing degree of the valve to regulate the amount of refrigerant entering the evaporator tube 10, so that the temperature inside the ice-making chamber 2101 is maintained within the refrigeration temperature range, thereby avoiding the evaporator tube 10 from becoming too cold or too hot, and thus ensuring the refrigeration effect of the evaporator tube 10. The "refrigeration temperature range" can be understood as the operating temperature range of the ice-making chamber 2101 when making ice. This embodiment does not impose a specific limitation on the refrigeration temperature range, which can be set according to actual usage requirements.

[0041] In this embodiment, to further prevent the evaporator tube 10 from becoming too cold or too hot and to ensure its cooling effect, the second pipe 40 is provided with a second channel 22 for transmitting heat medium to prevent the evaporator tube 10 from over-freezing or frosting. Specifically, the heat medium can be the hot gas generated by the compressor 202 during operation. Specifically, one end of the second pipe 40 is connected to the evaporator tube 10 via the input port 11, and the other end is connected to the compressor 202. By providing the second pipe 40, the heat generated during the compression process of the compressor 202 can be used to heat the evaporator tube 10 to prevent over-freezing or frosting, eliminating the need for an additional heat source and improving energy utilization. In some embodiments, the evaporative cooling device 100 may also include a control valve 50, which is disposed on the second pipe 40. The control valve 50 is electrically connected to the controller. When the temperature detected by the temperature sensor is outside the refrigeration temperature range, the controller can also control the control valve 50 to adjust the valve opening degree to control the flow of heat medium entering the evaporator tube 10, so that the temperature in the ice-making chamber 2101 is maintained within the refrigeration temperature range, thus ensuring the refrigeration effect of the evaporator tube 10.

[0042] To facilitate the connection between the first pipe 30 and the second pipe 40 and to minimize the size of the connector 20, in this embodiment, both the first channel 21 and the second channel 22 can extend in a straight line. The straight-lined first channel 21 and second channel 22 are easier to manufacture and readily aligned with the first pipe 30 and the second pipe 40, reducing installation errors and connection problems, thus improving installation efficiency and lowering installation costs. Furthermore, the straight-lined first channel 21 and second channel 22 reduce resistance to the flow of refrigerant and heat transfer fluids, minimizing energy loss and improving flow efficiency.

[0043] To further reduce the volume of the connector 20, in some embodiments, the first channel 21 and the second channel 22 can be arranged in parallel, so that the first pipe 30 and the second pipe 40 installed on the connector 20 are also arranged in parallel, which makes the layout of the connector 20 and the pipes more compact and improves the overall space utilization of the ice-making equipment 200. It should be noted that the parallel arrangement can mean that one of the first channel 21 and the second channel 22 is located above the other in the direction of gravity, or that the first channel 21 and the second channel 22 are arranged horizontally side by side.

[0044] It is understood that in some other embodiments, the first channel 21 and the second channel 22 may also be non-parallel. For example, the first channel 21 and the second channel 22 may be arranged approximately perpendicularly, or there may be an angle between the first channel 21 and the second channel 22, so that the first pipe 30 and the second pipe 40 can avoid obstacles and achieve reasonable space planning.

[0045] To improve the connection stability between the first pipe 30 and the first channel 21, and between the second pipe 40 and the second channel 22, in this embodiment, the first pipe 30 and the first channel 21 can be connected by a plug-in joint, and the second pipe 40 and the second channel 22 can also be connected by a plug-in joint. Specifically, the outer peripheral wall of the first pipe 30 can fit against the inner peripheral wall of the first channel 21, and the outer peripheral wall of the second pipe 40 can fit against the inner peripheral wall of the second channel 22. This can reduce pipe loosening and connection failure caused by vibration, and improve the connection stability and reliability between the joint 20 and the first pipe 30 and the second pipe 40. Furthermore, the tight fit between the first pipe 30 and the first channel 21, and between the second pipe 40 and the second channel 22, can reduce the risk of refrigerant and heat transfer fluid leakage, and improve the sealing performance of the joint 20 at the connection point. In some embodiments, a sealing element can also be provided between the first pipe 30 and the first channel 21, and between the second pipe 40 and the second channel 22. The sealing element is used to further enhance the sealing effect; the sealing element can be a sealing ring, a sealing gasket, or a sealant, and this embodiment does not impose specific limitations on this.

[0046] To ensure the stability and reliability of evaporator 10's cooling performance, in some embodiments, the inner diameter of the first channel 21 can be smaller than the inner diameter of the second channel 22, and the inner diameter of the first pipe 30 can be smaller than the inner diameter of the second pipe 40. The smaller inner diameter of the first pipe 30 allows for a more significant throttling and pressure reduction effect on the refrigerant within the first pipe 30, resulting in lower temperature and pressure of the refrigerant before it enters the evaporator 10 for evaporation. This reduces the energy consumption required for evaporation and improves cooling efficiency. Simultaneously, the larger inner diameter of the second pipe 40 facilitates the rapid entry of the heat transfer medium into the evaporator 10, reducing the occurrence of over-freezing or frosting on the evaporator 10.

[0047] Since connector 20 connects the first pipe 30, the second pipe 40, and the evaporator tube 10 simultaneously, to facilitate the connection of the first pipe 30, the second pipe 40, and the evaporator tube 10, connector 20 may include a first connecting segment 23, a second connecting segment 24, and a third connecting segment 25 connected in sequence. The second connecting segment 24 is connected between the first connecting segment 23 and the third connecting segment 25. The first connecting segment 23, the second connecting segment 24, and the third connecting segment 25 are all tubular. Specifically, the first connecting segment 23 is used to connect to the input port 11. The diameter of the first connecting segment 23 can match the diameter of the input port 11, so that the first connecting segment 23 can be inserted and mated with the input port 11. As an example, the outer peripheral wall of the first connecting section 23 and the inner peripheral wall of the input port 11 are fitted together, or the inner peripheral wall of the first connecting section 23 and the outer peripheral wall of the input port 11 are fitted together, which can improve the connection stability and sealing of the first connecting section 23 and the input port 11, thereby preventing refrigerant or heat medium leakage and ensuring the cooling effect of the ice-making equipment 200.

[0048] In this embodiment, both the first channel 21 and the second channel 22 penetrate the third connecting section 25, which is used to fix the first pipe 30 and the second pipe 40 within the connector 20. Specifically, the first channel 21 and the second channel 22 form a through-hole structure inside the third connecting section 25, allowing the first pipe 30 to be inserted into the first channel 21 and the second pipe 40 to be inserted into the second channel 22 for fixation within the third connecting section 25. This embodiment does not limit the length of the first pipe 30 within the first channel 21 or the length of the second pipe 40 within the second channel 22. As an example, the first pipe 30 penetrates the first channel 21, and the second pipe 40 penetrates the second channel 22; that is, at least a portion of the structure of the first pipe 30 and the second pipe 40 is disposed within the second connecting section 24 to improve the connection strength between the first pipe 30, the second pipe 40, and the connector 20.

[0049] As another example, the first pipe 30 can sequentially pass through the first connecting section 23, the second connecting section 24, and the third connecting section 25, which can increase the contact area between the first pipe 30 and the joint 20, reduce the shaking and displacement of the first pipe 30 during operation, and improve the stability of the connection. Furthermore, in some embodiments, the first pipe 30 can also protrude from the end of the first connecting section 23 away from the third connecting section 25 and be inserted into the evaporator tube 10. That is, the refrigerant directly contacts the evaporator tube 10 via the first pipe 30, which can reduce the risk of refrigerant backflow and ensure the cooling efficiency and cooling effect of the ice-making equipment 200. Similarly, in other embodiments, the second pipe 40 can also protrude from the end of the first connecting section 23 away from the third connecting section 25 and be inserted into the evaporator tube 10 so that the heat medium directly contacts the evaporator tube 10.

[0050] In this embodiment, the size of the first connecting section 23 can be smaller than the size of the third connecting section 25, thereby further reducing the risk of refrigerant and heat transfer medium flowing back from the inlet 11 to the third connecting section 25, so that as much refrigerant and heat transfer medium as possible enters the evaporator tube 10, ensuring the cooling effect of the evaporative cooling device 100. Since the sizes of the first connecting section 23 and the third connecting section 25 are different, the second connecting section 24 used to connect the first connecting section 23 and the third connecting section 25 can be set as a variable diameter section to match the sizes of the first connecting section 23 and the third connecting section 25, that is, the size of the end of the second connecting section 24 connected to the first connecting section 23 is smaller than the size of the end of the second connecting section 24 connected to the third connecting section 25.

[0051] In summary, this application provides an evaporative refrigeration device 100, which includes an evaporator 10, a connector 20, a first pipe 30, and a second pipe 40. By providing the first pipe 30, the second pipe 40, and the connector 20, it is ensured that the refrigerant can smoothly enter the evaporator 10 for cooling, while the heat medium can be transferred to the evaporator 10 through the second pipe 40 to prevent overcooling and icing or frosting, thereby ensuring the cooling efficiency and effect of the evaporator 10. Furthermore, the connector 20, as a connecting component, integrates the first pipe 30, the second pipe 40, and the evaporator 10 into a single connector by providing spaced-apart first channels 21 and second channels 22. This not only reduces external connecting components and effectively lowers piping complexity but also improves the overall compactness and reliability of the device.
