Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a flow path module and an air conditioner. Background Technology

[0002] In related technologies, the flow path module adopts a structure of a cover plate and a body, wherein the body is integrally formed and the flow channels on the body are structurally connected. Because the flow channels on the body are structurally connected, but different flow channels are located at different positions in the overall flow path during operation, and the refrigerant is in different states, the temperature between the flow channels is different, resulting in a temperature difference. Because metal has good thermal conductivity, this leads to more heat conduction, causing energy loss and adversely affecting energy efficiency. Therefore, how to reduce the heat transfer impact of the flow path module has become the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, one objective of this application is to propose a flow path module that can reduce the impact of heat transfer in the flow path module.

[0004] This application also proposes an air conditioner having the above-mentioned flow path module.

[0005] According to an embodiment of this application, a flow path module includes: a base and flow channel portions, wherein at least two flow channel portions are configured and connected to the base, and a refrigerant flow channel is formed within each flow channel portion, and at least two flow channel portions are spaced apart on the base.

[0006] According to the flow path module of the present application embodiment, by setting the flow channel sections apart to eliminate direct contact between the flow channels, the space between the flow channel sections forms a physical gap. The thermal conductivity of the air in this gap is much lower than that of metal, which reduces the heat conduction area between adjacent flow channel sections, reduces the amount of heat exchange between flow channels at different temperatures, and reduces the adverse effects of heat transfer on the overall flow path energy efficiency.

[0007] According to some embodiments of the present application, the base is provided with a first refrigerant port, the flow channel is provided on the base and the refrigerant flow channel is connected to the first refrigerant port; and / or, the flow channel is provided with a second refrigerant port and the second refrigerant port is connected to the refrigerant flow channel.

[0008] According to some embodiments of the present application, each of the flow channels is constructed as a block and any two flow channels are spaced apart from each other to form a gap for airflow channels.

[0009] According to some embodiments of the present application, the base is plate-shaped with a first surface and a second surface on both sides in the thickness direction; wherein a plurality of flow channels are respectively disposed on the first surface, and the second surface is provided with the first refrigerant port.

[0010] According to some embodiments of the present application, in the flow path module, the second refrigerant port provided on the flow channel is open away from the first surface and / or open parallel to the first surface.

[0011] According to some embodiments of the present application, the flow path module has a protruding annular interface on the second surface, the annular interface being arranged around the first refrigerant port.

[0012] According to some embodiments of the present application, the flow path module has a first positioning part on the base and a second positioning part on the flow channel part. The first positioning part and the second positioning part abut against each other to restrict the movement of the flow channel part relative to the base.

[0013] According to some embodiments of the flow path module of this application, the first positioning part is configured as a positioning protrusion protruding from the base surface, and the second positioning part is configured as a positioning surface on the surface of the flow channel part, the positioning surface abutting against the positioning protrusion.

[0014] According to some embodiments of the flow path module of this application, the positioning protrusion is constructed in an arc shape, and the positioning surface of the flow channel is constructed as an arc-shaped wall adapted to the positioning protrusion.

[0015] According to some embodiments of the present application, the base has a first groove recessed toward the side opposite to the flow channel portion, and at least one flow channel portion has a second groove recessed toward the inside of the flow channel portion. The internal spaces of the first groove and the second groove together define a first refrigerant flow channel.

[0016] According to some embodiments of the present application, at least one of the flow path modules has a second refrigerant flow path independently formed within it.

[0017] The flow path module according to some embodiments of this application further includes: a valve core component, which is movably disposed in the first refrigerant flow channel to selectively open or close the first refrigerant channel.

[0018] According to some embodiments of the present application, the base of the flow path module is further provided with a through heat dissipation hole, which avoids the flow channel portion.

[0019] The flow path module according to some embodiments of this application further includes: a filter element disposed in one of the flow channels, the filter element being adapted to filter refrigerant flowing through the refrigerant flow channel.

[0020] The air conditioner according to an embodiment of this application is briefly described below.

[0021] The air conditioner according to the embodiments of this application includes the flow path module of any of the above embodiments. Since the air conditioner according to this embodiment is equipped with the flow path module of any of the above embodiments, the air conditioner according to this application, with at least two flow channel sections spaced apart on the base, and no direct metal connection structure between the flow channel sections, but only indirect connection through the base, allows the refrigerant in the high-temperature side flow channel to maintain a high subcooling degree, reducing vaporization before entering the throttling element and improving throttling efficiency; the refrigerant in the low-temperature side flow channel can maintain a lower temperature, avoiding premature heat absorption before entering the evaporator, ensuring the heat exchange of the evaporator. Under this combined effect, the air conditioner's refrigerant circulation system can complete heat exchange more efficiently, and the compressor does not need to consume excessive energy to compensate for heat loss, thereby reducing the air conditioner's operating power consumption and improving the overall energy efficiency level. Furthermore, the reduction in heat transfer between flow channels can also reduce mutual interference between the refrigerant states in different flow channels, making the refrigerant circulation more stable, reducing frequent compressor start-stop due to state fluctuations, and further extending the operating life of the air conditioner.

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] The following is for reference. Figures 1-8 Describes a flow path module 100 according to an embodiment of this application.

[0027] According to an embodiment of this application, the flow path module 100 includes: a base 1 and a flow channel 2. The flow channel 2 is configured to be at least two and connected to the base 1. A refrigerant flow channel 21 is formed in the flow channel 2. The at least two flow channel 2 are spaced apart on the base 1.

[0028] In related technologies, the main body of the flow path module is integrally formed, and the flow channels are directly connected by a metal structure to form a continuous heat conduction path. When the refrigerant in different flow channels is in different states, the temperature difference between the flow channels will be quickly conducted through the connecting structure of the metal body. The heat of the high-temperature flow channel is directly transferred to the low-temperature flow channel through the connecting structure. Because the metal has a high thermal conductivity, a lot of heat is transferred per unit time, which causes the high-temperature flow channel to consume additional energy to maintain the temperature, while the low-temperature flow channel reduces its efficiency due to heat absorption, resulting in significant energy loss.

[0029] It is understood that in the flow path module 100 of this application embodiment, at least two flow channel sections 2 are connected to the base 1 and are spaced apart on the base 1, so that there is no direct metal connection structure between the flow channel sections 2. The space between the flow channel sections 2 forms a physical gap. The thermal conductivity of the air in this gap is much lower than that of the metal. When there is a temperature difference in the refrigerant in the refrigerant flow channel 21 in different flow channel sections 2, the heat transfer path changes. The heat of the high-temperature side flow channel section 2 needs to be transferred to the base 1 first, and then transferred from the base 1 to the low-temperature side flow channel section 2, or through the gap between the flow channel sections 2 for heat radiation and air convection. Since the connection between the base 1 and the flow channel section 2 is only a local contact, the heat conduction area is greatly reduced compared to the large-area connection of the integral molded body. At the same time, the gap formed by the interval of the flow channel sections 2 blocks the main heat conduction path of direct metal connection, and the heat transfer rate through the air is much lower than that of direct metal conduction. In addition, each flow channel 2 independently carries the refrigerant flow channel 21, and there is no continuous metal structure between the flow channels. This avoids the efficient heat conduction channels formed by the body connection structure between the flow channels in related technologies, thereby reducing the amount of heat exchange between flow channels at different temperatures and reducing the adverse effects of heat transfer on the overall flow path energy efficiency.

[0030] It should be noted that the refrigerant flow channel 21 formed inside the flow channel section 2 can be that the flow channel section 2 is already a complete independent unit with its own internal pipe structure during manufacturing, and the refrigerant flow channel 21 can be formed independently inside the flow channel section 2; or the refrigerant flow channel 21 can be formed by assembling the flow channel section 2 and the base 1, and the cavity formed between the flow channel section 2 and the base 1 serves as the refrigerant flow channel 21.

[0031] In short, by spacing the flow channel sections 2 to eliminate direct contact between flow channels, the space between the flow channel sections 2 forms a physical gap. The thermal conductivity of the air in this gap is much lower than that of metal, which reduces the heat conduction area between adjacent flow channel sections 2, reduces the amount of heat exchange between flow channels at different temperatures, and reduces the adverse effects of heat transfer on the overall flow path energy efficiency.

[0032] According to some embodiments of the present application, the flow path module 100 has a first refrigerant port 11 on the base 1, a flow channel 2 on the base 1 and a refrigerant flow channel 21 communicating with the first refrigerant port 11; and / or, a second refrigerant port 22 is provided on the flow channel 2 and the second refrigerant port 22 is communicating with the refrigerant flow channel 21.

[0033] Understandably, the integration of the first refrigerant port 11 with the base 1 allows the external pipe 6 to directly connect with the base 1, avoiding the need for the external pipe 6, which is connected to the refrigerant flow path, to detour to connect with the flow channel section 2 or the base 1. This also avoids the external pipe 6 occupying extra space due to detours. The second refrigerant port 22 on the flow channel section 2 can be connected to adjacent components or extended through the external pipe 6. When the flow channel section 2 connects the first refrigerant port 11 on the base 1 and the flow channel section 2 is provided with the second refrigerant port 22, a refrigerant flow channel 21 connecting the second refrigerant port 22 and the first refrigerant port 11 can be formed. The refrigerant flow channel 21 runs through the base 1, which can reduce the probability of pipe cross-interference and avoid the interface congestion problem caused by the dense flow channels in the overall molding structure. This reduces the redundant space reserved to avoid interference and reduces the space occupied by the flow path module 100.

[0034] It should be noted that the first refrigerant port 11 is suitable for connection with a plate heat exchanger, and the other refrigerant ports on the flow channel section 2 are configured as second refrigerant ports 22. According to some embodiments of the present application, each flow channel 2 of the flow path module 100 is constructed as a block and any two flow channel sections 2 are spaced apart from each other to form a gap for airflow channels.

[0035] First, since there is no direct metal connection between the block-shaped flow channels 2, the original continuous solid heat conduction path is blocked. Therefore, heat transfer between the flow channels 2 must be achieved through the air in the gaps. The thermal conductivity of air is much lower than that of metal materials, which significantly reduces the rate of heat conduction through the gaps.

[0036] Simultaneously, airflow can flow within the gaps, carrying away some of the heat from the surface of the flow channel 2, forming convective heat transfer. Unlike the static heat conduction of metal connection structures in related technologies, convective heat transfer does not directly transfer heat to another flow channel 2, but rather dissipates the heat into the environment, reducing the net heat exchange between the flow channel 2. The spacing of the block-shaped flow channel 2 reduces the relative surface area of ​​the two flow channel 2. Compared to the large area of ​​metal contact between the flow channels in the integral molding structure, the heat exchange area is significantly reduced. According to Fourier's law, the amount of heat transfer is positively correlated with the heat exchange area. Therefore, the reduction in the heat exchange area further reduces the total amount of heat transfer between the flow channel 2, reducing the impact of heat transfer on the flow path module 100.

[0037] According to some embodiments of the present application, the flow path module 100 has a base 1 constructed as a plate with a first surface 12 and a second surface 13 on both sides in the thickness direction; wherein a plurality of flow channels 2 are respectively disposed on the first surface 12, and a first refrigerant port 11 is disposed on the second surface 13.

[0038] In the prior art, the flow path module is an integrally molded structure, with the flow channel and refrigerant interface both integrated on the flow path module 100. The position of the interface and flow channel is limited by the integral molding process, and they are usually distributed on the same side or adjacent side of the body. This results in a large space needing to be reserved around the flow path module to avoid interference when connecting external pipelines. Furthermore, when there are many flow channels, the dense distribution of interfaces can easily cause pipelines to cross and entangle, further increasing the installation space requirements.

[0039] The thickness direction of the plate-shaped base 1 forms two independent functional surfaces. The first surface 12 is used to support the flow channel section 2, and the second surface 13 is used to set the first refrigerant port 11. The layered layout separates the installation area of ​​the flow channel section 2 from the connection area of ​​the refrigerant interface in space, avoiding the space occupancy of the flow channel and interface on the same plane in related technologies. For example, when the flow channel section 2 occupies a large area on the first surface 12 due to its large number, the first refrigerant port 11 on the second surface 13 can be independently planned without being restricted by the distribution of the flow channel section 2. At the same time, the first refrigerant port 11 is set on the second surface 13 of the base 1 and can be directly connected to the piping system on the other side of the equipment, reducing the detour length of the pipeline around the first surface 12 where the flow channel section 2 is located. The flow channel section 2 is set at intervals on the first surface 12, and its own second refrigerant port 22 can face other directions of the equipment to realize multi-directional pipeline connection, avoiding pipeline congestion caused by all interfaces being concentrated in a single direction, and reducing the radial dimension requirements of the installation space. Moreover, the plate-shaped base 1 has a smaller thickness dimension. Compared with the integrally formed flow path module 100, the plate-shaped flow path module 100 occupies less vertical space in the equipment. The connection between the flow channel section 2 and the base 1 does not require an additional support structure. The integrated design of the first refrigerant port 11 and the base 1 eliminates the transition connector between the interface and the body, making the overall volume of the flow path module 100 more compact, thus adapting to the installation requirements of the narrow space in the equipment.

[0040] According to some embodiments of the present application, in the flow path module 100, the second refrigerant port 22 provided on the flow channel 2 is open away from the first surface 12 and / or open parallel to the first surface 12.

[0041] Understandably, when the second refrigerant port 22 is open away from the first face 12 (i.e., facing a direction perpendicular to the first face 12), it can directly connect to the component located on the opposite side of the first face 12 in the flow path module 100, without the need for the pipeline to detour in the horizontal direction, thus reducing the number of bends and the horizontal projected area of ​​the pipeline. When the second refrigerant port 22 is open parallel to the first face 12 (i.e., facing a direction parallel to the first face 12), it can be adapted to the lateral interface located in the same horizontal plane of the flow path module 100 in the equipment, realizing a direct horizontal connection of the pipeline. The combination of the two opening directions allows the second refrigerant port 22 to flexibly match the interface position of different components in the equipment, avoiding the problem of forced pipeline turning caused by the single interface direction in related technologies, and reducing the spatial restrictions on pipeline connection. Furthermore, since the second refrigerant inlet 22 can be opened either away from or parallel to the first surface 12, when the flow channels 2 are densely distributed on the first surface 12 of the base 1, the second refrigerant inlet 22 open parallel to the first surface 12 can extend horizontally to the side of the flow channel 2, avoiding collision with the second refrigerant inlet 22 of adjacent flow channel 2 in the vertical direction; while the second refrigerant inlet 22 open away from the first surface 12 extends outward into the space of the base 1, away from the cluster of flow channel 2 on the first surface 12, reducing the spatial overlap between flow channel 2 and between flow channel 2 and pipeline. This multi-directional open design allows the connecting pipelines of each second refrigerant inlet 22 to be arranged in an orderly manner within the limited installation space, without the need to reserve excessive redundant space to avoid interfaces, thus improving the utilization rate of the internal space of the equipment.

[0042] According to some embodiments of the present application, the flow path module 100 has a protruding annular interface 131 on its second surface 13, and the annular interface 131 is arranged around the first refrigerant port 11.

[0043] The annular interface 131 protrudes along the second surface 13 to form a solid structure. The inner wall of the annular interface 131 can form a mating gap with the end of the external pipe 6. When the external pipe 6 is connected to the first refrigerant port 11, the inner wall of the annular interface 131 can provide radial guidance for the insertion direction of the pipe, limiting the horizontal offset of the pipe and enabling the central axis of the pipe to be quickly aligned with the central axis of the first refrigerant port 11. This avoids repeated adjustments due to inaccurate positioning in related technologies and shortens the connection time. At the same time, the protruding structure of the annular interface 131 can provide a clear reference for gripping or applying force. When manually connecting the pipe, the connection position can be perceived by touching the annular interface 131 without continuous visual confirmation. When using tools to tighten, the outer wall of the annular interface 131 can serve as a fulcrum for tools such as wrenches, limiting the rotation of the pipe during the tightening process and preventing the interface from twisting due to the synchronous rotation of the pipe with the fastener, thus reducing the difficulty of the connection operation.

[0044] According to some embodiments of the present application, the flow path module 100 has a first positioning part on the base 1 and a second positioning part on the flow channel 2. The first positioning part and the second positioning part abut against each other to restrict the flow channel 2 from moving relative to the base 1.

[0045] The contact structure between the first and second positioning parts provides a rigid constraint for the installation of the flow channel 2 on the base 1. This contact constraint ensures that the flow channel 2 can be accurately installed in the preset position, guaranteeing that the spacing between each flow channel 2 and the relative position of the flow channel 2 to the edge of the base 1 meet design requirements. This avoids the problem of flow channel 2 offset due to inaccurate positioning and provides a structural foundation for subsequent refrigerant interface connection and airflow clearance maintenance. Simultaneously, the contact between the first and second positioning parts can share the external forces on the flow channel 2 within the flow path module 100. During operation, the refrigerant flowing in the channel generates pulsating pressure. This pressure is transmitted through the channel section 2 to the connection point with the base 1. Since the first positioning section and the second positioning section abut against each other, the pulsating pressure can be transmitted to the base 1 through the abutting surface, reducing the stress load on the connection point and preventing the connection point from loosening due to long-term stress. When the flow path module 100 is subjected to external vibration, the abutting structure can limit the shaking of the channel section 2 relative to the base 1, preventing the connection point from being damaged due to repeated friction or impact, thus improving the overall structural reliability of the flow path module 100.

[0046] According to some embodiments of the present application, the flow path module 100 has a first positioning part configured as a positioning protrusion 14 protruding from the surface of the base 1, and a second positioning part configured as a positioning surface 23 on the surface of the flow channel part 2, wherein the positioning surface 23 abuts against the positioning protrusion 14.

[0047] The positioning protrusion 14 protrudes from the surface of the base 1, forming a clear rigid positioning reference. When the positioning surface 23 of the flow channel 2 abuts against the side of the positioning protrusion 14, the direct contact between the surfaces restricts the translational freedom of the flow channel 2 on the surface of the base 1, avoiding the problem of positioning failure caused by the gap between the positioning surface 23 and the positioning protrusion 14. This allows the installation position deviation of the flow channel 2 to be controlled within the fit tolerance range of the positioning protrusion 14 and the positioning surface 23. The abutment between the positioning protrusion 14 and the positioning surface 23 provides a fulcrum for distributing the force on the flow channel 2. When the flow channel 2 is subjected to the lateral force generated by the flow of refrigerant, the force can be transmitted to the positioning protrusion 14 through the positioning surface 23, and then dispersed to the entire base 1 by the positioning protrusion 14. This avoids the force being concentrated at the connection between the flow channel 2 and the base 1, reduces the stress load at the connection, reduces the risk of damage to the connection due to excessive force, and improves the structural stability of the flow path module 100.

[0048] According to some embodiments of the present application, the flow path module 100 has an arc-shaped positioning protrusion 14 and an arc-shaped wall adapted to the positioning protrusion 14.

[0049] The arc-shaped positioning protrusion 14 and the arc-shaped wall positioning surface 23 form a curved contact. The contact area is a continuous arc surface. Compared with the surface contact of a planar contact, the arc surface has a larger contact area and a more uniform stress distribution for the same projected area. When the flow channel 2 is subjected to a torque about an axis perpendicular to the surface of the base 1, the arc wall may have a slight relative sliding tendency along the arc surface of the positioning protrusion 14. However, due to the radial constraint of the arc surface, the torque will be converted into a component force along the tangential direction of the arc. This component force can be transmitted to the positioning protrusion 14 through the entire contact arc surface, avoiding stress concentration at a certain point or line, reducing the risk of damage to the positioning structure due to excessive force, and ensuring the stability of the positioning function during long-term use.

[0050] According to some embodiments of the present application, the flow path module 100 has a first groove 15 recessed on the base 1 toward the side opposite to the flow channel portion 2, and a second groove 24 recessed toward the inside of the flow channel portion 2 is formed in at least one flow channel portion 2. The internal spaces of the first groove 15 and the second groove 24 together define a first refrigerant flow channel 211.

[0051] Understandably, the first groove 15 is recessed towards the side opposite to the flow channel 2, that is, it extends into the internal space of the base 1, and the second groove 24 is recessed towards the inside of the flow channel 2, that is, it extends into the internal space of the flow channel 2. The recessed directions of the two are complementary, so that the space of the first refrigerant flow channel 211 is not provided by the single structure of the base 1 or the flow channel 2, but combines the internal spaces of the base 1 and the flow channel 2. In the thickness direction of the base 1, the first groove 15 can occupy a part of the thickness of the base 1, and in the thickness direction of the flow channel 2, the second groove 24 can occupy a part of the thickness of the flow channel 2. The height of the flow channel formed after the two are spliced ​​together is the sum of the depth of the first groove 15 and the depth of the second groove 24, which significantly increases the height dimension of the first refrigerant flow channel 211, which can increase the flow rate of the first refrigerant flow channel 211, and also provides operating space for setting other components in the first refrigerant flow channel 211.

[0052] According to some embodiments of the present application, in the flow path module 100, at least one of the flow channel portions 2 has a second refrigerant flow channel 212 independently formed therein.

[0053] It is understandable that the independently formed second refrigerant channel 212 is formed inside a single channel section 2. The second refrigerant channel 212 is independently formed within the channel section 2. The channel wall of the second refrigerant channel 212 only contacts the structure of the channel section 2 where it is located, and has no contact area with the outer wall of other channels. In this application, the outer walls of different channels are respectively wrapped by the structure of their respective channel sections 2. The heat exchange between channels needs to be carried out indirectly through the outer surface of the channel section 2. The area that actually participates in the heat exchange is only a local surface between the gaps of the channel section 2 and the channel section 2, which is much smaller than the common wall area of ​​the integrally formed channel. According to the basic principle of heat conduction, the amount of heat transfer is positively correlated with the heat exchange area. Therefore, the reduction of the heat exchange area directly reduces the total amount of heat transfer between channels.

[0054] The flow path module 100 according to some embodiments of this application further includes: a valve core component 4, which is movably disposed in the first refrigerant flow channel 211 to selectively open or close the first refrigerant channel.

[0055] The valve core component 4 is built into the first refrigerant flow channel 211, eliminating the need for pipes and interfaces connecting external valves. This allows the flow path module 100 to perform both flow path delivery and on / off control functions, reducing the number of components in the flow path system and lowering control deviations caused by assembly errors between components. The sealing surface of the valve core component 4 can directly mate with the inner wall of the first refrigerant flow channel 211, avoiding the impact of pressure drop from the external pipe 6 on the valve control accuracy. This ensures that the valve core component 4 can quickly respond to changes in the refrigerant state within the flow path when it operates. Located inside the first refrigerant flow channel 211, the valve core component 4 can change the on / off state of the flow path when it moves. When open, the refrigerant can pass through the flow cross-section formed by the valve core component 4; when closed, the valve core component 4 can block the refrigerant flow. The built-in valve core component 4 shortens the on / off control response time of the flow path and improves the dynamic adjustment accuracy of the flow path system.

[0056] According to some embodiments of the present application, the flow path module 100 is provided with a through heat dissipation hole 16 on the base 1, and the heat dissipation hole 16 avoids the flow channel portion 2.

[0057] The through-hole 16 provides an air convection channel for the base 1. When the flow path module 100 is working, the heat generated by the refrigerant flow in the flow channel 2 is transferred to the base 1, causing the base 1 temperature to rise. At this time, the air inside the through-hole 16 can exchange heat with the hole wall of the base 1. The heat from the hole wall is transferred to the air, causing the air temperature to rise and natural convection to occur due to the density difference. Hot air flows out from one end of the through-hole, and cold air flows in from the other end, forming a continuous airflow circulation, which accelerates the dissipation of heat from the base 1. At the same time, the through-hole increases the contact area between the base 1 and the external environment. The inner wall of the through-hole becomes an additional heat dissipation surface. Compared with the solid base 1, which only dissipates heat through its outer surface, the increased heat dissipation area improves the heat exchange efficiency. In addition, the through-hole 16 avoids the flow channel 2, ensuring that the connection between the flow channel 2 and the base 1 is not affected by the through-hole. Heat can be transferred to the solid part of the base 1 through the connection and then quickly dissipated through the through-hole, avoiding heat accumulation near the flow channel 2.

[0058] Furthermore, the through-hole 16 forms a hollow structure on the base 1, directly removing the base 1 material at the location of the through-hole. Since the heat dissipation through-hole 16 avoids the flow channel 2, that is, the through-hole is opened in the area of ​​the base 1 that is not connected to the flow channel 2, the material removal in the above-mentioned area will not affect the support strength of the base 1 for the flow section. The installation position of the flow channel 2 still retains sufficient solid structure of the base 1 to ensure connection rigidity, while the material removal in the through-hole area reduces the overall mass of the base 1. Under the premise of ensuring structural strength, the number and diameter of the heat dissipation through-hole 16 can be designed according to the weight reduction requirements. Lightweighting is achieved through local material removal, and the through-hole structure avoids redundant material accumulation, further optimizing the mass distribution of the base 1.

[0059] The flow path module 100 according to some embodiments of this application further includes a filter element 5, which is disposed in one of the flow channels 2 and is adapted to filter the refrigerant flowing through the refrigerant flow channel 21.

[0060] The filter element 5 is built into the flow channel section 2, eliminating the need for additional external piping 6 and installation space. This reduces the overall volume of the flow module 100 and avoids the need for external filters to be connected to piping via flanges and bolts. The built-in filter element 5 eliminates connecting parts, simplifying the overall structure of the flow system and reducing the risk of assembly errors caused by an increase in components. Furthermore, the integrated design of the filter element 5 and the flow channel section 2 reduces the number of parts in the flow module 100, which is beneficial for simplifying the production process and controlling costs. Furthermore, a filter element 5 is provided inside the flow channel section 2. The filter element 5 can concentrate impurities on one side of the filter element 5 to facilitate the centralized cleaning of impurities. For the refrigerant flow channel 21, the filter element 5 reduces the possibility of impurities entering the subsequent pipeline and protects other components in the flow channel system from wear or blockage.

[0061] The air conditioner according to an embodiment of this application is briefly described below.

[0062] The air conditioner according to the embodiments of this application includes the flow path module 100 of any of the above embodiments. Since the air conditioner according to this embodiment is provided with the flow path module 100 of any of the above embodiments, the air conditioner according to this application has at least two flow channel parts 2 spaced apart on the base 1. There is no direct metal connection structure between the flow channel parts 2, and they are only indirectly connected through the base 1. This allows the refrigerant in the high-temperature flow channel to maintain a high degree of subcooling, reducing the temperature drop before entering the throttling element and improving the throttling efficiency. The refrigerant in the low-temperature flow channel can maintain a lower temperature, avoiding premature heat absorption before entering the evaporator and ensuring the heat exchange of the evaporator. Under the combined effect, the refrigerant circulation system of the air conditioner can complete heat exchange more efficiently. The compressor does not need to consume too much extra energy to make up for heat loss, thereby reducing the operating power consumption of the air conditioner and improving the overall energy efficiency level. In addition, the reduction of heat transfer between flow channels can also reduce the mutual interference of refrigerant states in different flow channels, making the refrigerant circulation more stable, reducing the frequent start-stop of the compressor caused by state fluctuations, and further extending the service life of the air conditioner.
