Detailed Implementation

[0032] The embodiments of this utility model 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 utility model, and should not be construed as limiting this utility model.

[0033] The following is for reference. Figures 1-7 Description of the current collector 100 according to an embodiment of the present utility model.

[0034] Reference Figures 1-4According to an embodiment of the present invention, the heat exchanger's flow collector 100 includes a flow collector plate 10, which includes a first substrate 11 and a second substrate 12. The second substrate 12 is connected to one side of the first substrate 11 in the thickness direction. A first flow channel 111 and a second flow channel 112 are defined between the second substrate 12 and the first substrate 11. One of the first flow channel 111 and the second flow channel 112 is an input flow channel and the other is an output flow channel.

[0035] In other words, the current collector 10 includes a first substrate 11 and a second substrate 12 arranged in its thickness direction. The first substrate 11 and the second substrate 12 are stacked together and connected, and can jointly define the first flow channel 111 and the second flow channel 112.

[0036] When the heat exchanger 200 is used in an air conditioning system, the first flow channel 111 and the second flow channel 112 can be used to flow refrigerant. If the first flow channel 111 is the input flow channel, the second flow channel 112 is the output flow channel. The refrigerant can enter different parts of the heat exchanger 200 (e.g., different heat exchange tubes 211) from the first flow channel 111. After heat exchange in the heat exchanger 200, the refrigerant flows to the second flow channel 112 and then flows to the next component of the air conditioning system through the second flow channel 112.

[0037] If the second flow channel 112 is the input flow channel, then the first flow channel 111 is the output flow channel. The refrigerant can enter different parts of the heat exchanger 200 from the second flow channel 112. After heat exchange in the heat exchanger 200, the refrigerant flows to the first flow channel 111 and then flows to the next component of the air conditioning system through the first flow channel 111.

[0038] According to the embodiment of the present invention, the heat exchanger manifold 100, compared with the related technology that uses separate inlet and outlet pipes, defines the separated first flow channel 111 and second flow channel 112 by the first substrate 11 and the second substrate 12 of the manifold 10. This can integrate the inlet and outlet flow channels of the refrigerant into one, which can simplify the installation steps, improve production efficiency and reduce production costs. On the other hand, it can achieve a compact structure and save installation space.

[0039] Reference Figure 2 and Figure 3 In some embodiments, the first substrate 11 and the second substrate 12 are formed separately and then welded together. For example, the first substrate 11 and the second substrate 12 can be formed by stamping two separate sheets.

[0040] In the above technical solution, by molding the first substrate 11 and the second substrate 12 separately, the molding difficulty of each substrate can be reduced, thereby improving the production efficiency of the current collector 10. If the structures of the first substrate 11 and the second substrate are roughly the same, the cost of molds and tooling can also be reduced, thereby reducing the production cost. On the other hand, it is easy to ensure the manufacturing precision of each substrate, thereby improving the quality of the current collector 10.

[0041] Of course, the first substrate 11 and the second substrate 12 can also be connected by adhesive bonding, snap-fitting, or fasteners.

[0042] In some embodiments, the first substrate 11 and the second substrate 12 may be made of metal materials, such as steel, and an anti-corrosion layer may be provided on the surface of the first substrate 11 and the second substrate 12 to prevent corrosion.

[0043] Reference Figure 3 In some embodiments, the first substrate 11 and the second substrate 12 are recessed in a direction away from each other, so that a first groove 101 and a second groove 102 are formed on the side of the first substrate 11 and the second substrate 12 facing each other, and a first protrusion 103 corresponding to the first groove 101 and a second protrusion 104 corresponding to the second groove 102 are formed on the side of the first substrate 11 and the second substrate 12 facing away from each other. The two first grooves 101 surround to form a first flow channel 111, and the two second grooves 102 surround to form a second flow channel 112.

[0044] Specifically, a portion of the first substrate 11 is recessed in a direction away from the second substrate 12 to form a first groove 101 and a second groove 102 spaced apart on the side of the first substrate 11 facing the second substrate 12, and a first protrusion 103 and a second protrusion 104 spaced apart on the side of the first substrate 11 facing away from the second substrate 12.

[0045] A portion of the second substrate 12 is recessed in a direction away from the first substrate 11 to form a first groove 101 and a second groove 102 spaced apart on the side of the second substrate 12 facing the first substrate 11, and a first protrusion 103 and a second protrusion 104 spaced apart on the side of the first substrate 11 facing away from the second substrate 12.

[0046] After the first substrate 11 and the second substrate 12 are connected, the first groove 101 of the first substrate 11 and the first groove 101 of the second substrate 12 surround each other to form a first flow channel 111, and the second groove 102 of the first substrate 11 and the second groove 102 of the second substrate 12 surround each other to form a second flow channel 112.

[0047] In the above technical solution, by forming a first groove 101 and a second groove 102 on both the first substrate 11 and the second substrate 12, on the one hand, the two first grooves 101 can be used to form a first flow channel 111 and the two second grooves 102 can be used to form a second flow channel 112, thereby increasing the volume of the first flow channel 111 and the second flow channel 112, thereby increasing the heat transfer capacity and efficiency of the current collector 10. On the other hand, the structural strength of the first substrate 11 and the second substrate 12 can be increased, thereby improving the reliability of the current collector 10.

[0048] Reference Figure 4 and Figure 5 In some embodiments, at least a portion of the first flow channel 111 and at least a portion of the second flow channel 112 are arranged at intervals in a first direction, and at least a portion of the first flow channel 111 and at least a portion of the second flow channel 112 extend along a second direction, with the first direction, the second direction and the thickness direction being perpendicular to each other.

[0049] in, Figure 4 In this context, F1 is the first direction and F2 is the second direction. Here, the first direction can refer to the width direction of the manifold 10, and the second direction can refer to the length direction of the manifold 10. The first flow channel 111 and the second flow channel 112 can be spaced apart in the width direction of the manifold 10, and at least a portion of the first flow channel 111 and at least a portion of the second flow channel 112 extend in the length direction of the manifold 10.

[0050] This configuration can lengthen the first flow channel 111 and the second flow channel 112, allowing the refrigerant to flow longer within the first flow channel 111 or the second flow channel 112. On the one hand, this makes the refrigerant flow within the first flow channel 111 or the second flow channel 112 more stable, ensuring the stable operation of the heat exchanger 200. On the other hand, it allows the first flow channel 111 or the second flow channel 112 to be connected to multiple heat exchange tubes 211 of the heat exchanger 200, thereby diverting the refrigerant to multiple heat exchange tubes 211 or merging the refrigerant from multiple heat exchange tubes 211 together.

[0051] Reference Figure 6 In some specific embodiments, the first flow channel 111 is an input flow channel, the second flow channel 112 is an output flow channel, and the maximum flow area of ​​the first flow channel 111 is greater than the maximum flow area of ​​the second flow channel 112.

[0052] Therefore, by setting the maximum flow area of ​​the first flow channel 111 to be greater than the maximum flow area of ​​the second flow channel 112, the flow velocity of the refrigerant in the first flow channel 111 is reduced. When the refrigerant enters the heat exchanger 200 for heat exchange, the flow time of the refrigerant in the heat exchanger 200 can be extended, which helps to improve the heat exchange efficiency of the heat exchanger 200.

[0053] In addition, this design can also accommodate the volume change of the refrigerant during the heat exchange process. For example, when the refrigerant condenses or cools in the heat exchanger 200, it changes from a gaseous state to a liquid state, and its volume is greatly reduced. The first flow channel 111, which has a larger flow area, allows the larger volume of gaseous refrigerant to flow, while the second flow channel 112, which has a smaller flow area, allows the smaller volume of liquid refrigerant to flow.

[0054] Reference Figures 4-5 , Figure 7 In some specific embodiments, the first flow channel 111 has a first total inlet / outlet 111a and a plurality of first heat exchange inlets / outlets 111b. The first total inlet / outlet 111a and the plurality of first heat exchange inlets / outlets 111b are all connected to the first flow channel 111. The plurality of first heat exchange inlets / outlets 111b are arranged at intervals in the extension direction of the first flow channel 111. The first heat exchange inlets / outlets 111b are used to communicate with the heat exchange flow channel 210 of the heat exchanger 200. The second flow channel 112 has a plurality of second heat exchange inlets / outlets 112a. The plurality of second heat exchange inlets / outlets 112a are all connected to the second flow channel 112 and are arranged at intervals in the extension direction of the second flow channel 112. The second heat exchange inlets / outlets 112a are used to communicate with the heat exchange flow channel 210 of the heat exchanger 200.

[0055] In other words, the first total inlet / outlet 111a can function as both the first total inlet and the first total outlet; the first heat exchange inlet / outlet 111b can function as both the first heat exchange inlet and the first heat exchange outlet; and the multiple second heat exchange inlets / outlets 112a can function as both the second heat exchange inlets and the second heat exchange outlets. When the first total inlet / outlet 111a functions as the first total inlet, the first heat exchange inlet / outlet 111b can be used as the first heat exchange outlet; when the first total inlet / outlet 111a functions as the first total outlet, the first heat exchange inlet / outlet 111b can be used as the first heat exchange inlet.

[0056] In the above technical solution, by arranging multiple first heat exchange inlets and outlets 111b in the extension direction of the first flow channel 111, when the first heat exchange inlets and outlets 111b are used as first heat exchange outlets, more refrigerant in the first flow channel 111 can be diverted through the multiple first heat exchange inlets and outlets 111b, thereby entering different parts of the heat exchanger 200, increasing the contact area between the heat exchanger 200 and the refrigerant, which is beneficial to improving the heat exchange efficiency of the heat exchanger 200; when the first heat exchange inlets and outlets 111b are used as first heat exchange inlets, the refrigerant in the first flow channel 111 can be converged.

[0057] By arranging multiple second heat exchange inlets and outlets 112a in the extension direction of the second flow channel 112, when the second heat exchange inlets and outlets 112a are used as second heat exchange inlets, the refrigerant after heat exchange in the heat exchanger 200 can flow out of the heat exchanger 200 from the multiple second heat exchange inlets and outlets 112a, and flow to the next component of the air conditioning system after converging, which is beneficial to improving the heat exchange efficiency of the heat exchanger 200; when the second heat exchange inlets and outlets 112a are used as second heat exchange outlets, the refrigerant in the heat exchanger 200 can be diverted.

[0058] For example, when the second heat exchange inlet / outlet 112a is used as the second heat exchange inlet, when there is a large amount of refrigerant after heat exchange in the heat exchanger 200, the refrigerant after heat exchange can flow evenly from multiple second heat exchange inlets / outlets 112a to the second flow channel 112, so that each second heat exchange inlet / outlet 112a bears a relatively stable flow rate, ensuring that the refrigerant can flow relatively smoothly after flowing into the second flow channel 112 from multiple second heat exchange inlets / outlets 112a.

[0059] Reference Figure 4 and Figure 5 In some examples, multiple first heat exchange inlets and outlets 111b and multiple second heat exchange inlets and outlets 112a are located on the same side of the thickness direction of the manifold 10, wherein the extension direction of the first heat exchange inlets and outlets 111b is consistent with the extension direction of the second heat exchange inlets and outlets 112a, and the extension direction of the first heat exchange inlets and outlets 111b and the extension direction of the first total inlet and outlet 111a are set at an angle.

[0060] In the above technical solution, by setting multiple first heat exchange inlets and outlets 111b and multiple second heat exchange inlets and outlets 112a on the same side of the thickness direction of the manifold 10, the layout of the manifold 100 can be simplified and space can be saved, so that the manifold 100 only needs to be connected to the heat exchanger 200 from one side. On the other hand, the assembly and disassembly operations only need to be carried out on one side, which greatly improves the assembly and disassembly efficiency.

[0061] By setting the extension directions of the first heat exchange inlet / outlet 111b and the second heat exchange inlet / outlet 112a to be consistent, the flow distance of the refrigerant entering the heat exchanger 200 from the input channel and the refrigerant flowing out of the heat exchanger 200 are similar. This ensures that the flow velocities of the refrigerant flowing into and out of the heat exchanger 200 are similar, thus avoiding the impact on the heat exchange efficiency of the heat exchanger 200 due to a large difference in the amount of refrigerant flowing into and out of the heat exchanger 200.

[0062] Furthermore, by setting the extension direction of the first heat exchange inlet / outlet 111b at an angle to the extension direction of the first total inlet / outlet 111a, pipelines can be installed from different directions, allowing the pipelines to effectively avoid surrounding components and preventing increased installation difficulty due to pipeline concentration.

[0063] Reference Figure 5 In some specific examples, the extension direction of the first heat exchange inlet / outlet 111b and the extension direction of the second heat exchange inlet / outlet 112a both extend along the thickness direction of the manifold 10. The first substrate 11 and the second substrate 12 enclose the first total inlet / outlet 111a, and the extension direction of the first total inlet / outlet 111a is perpendicular to the thickness direction of the manifold 10.

[0064] In the above technical solution, the first total inlet and outlet 111a is formed by the first substrate 11 and the second substrate 12. On the one hand, it can reduce the drilling operation and reduce the processing difficulty, and also avoid deformation of the first substrate 11 or the second substrate 12 due to drilling. On the other hand, the extension direction of the first total inlet and outlet 111a can be perpendicular to the thickness direction of the manifold 10. This allows the liquid inlet pipe and the liquid storage pipe to be installed from different directions, so that the pipeline can effectively avoid the surrounding components and avoid the increased installation difficulty due to the concentration of pipelines.

[0065] Reference Figure 4 and Figure 6 In some embodiments, the first flow channel 111 includes a first extension cavity 111c and a first flow passage cavity 111d, and a plurality of first extension cavities 111c and a plurality of first flow passage cavities 111d are arranged alternately and connected.

[0066] Among them, the positions of multiple first heat exchange inlets and outlets 111b correspond one-to-one with and are connected to multiple first flow chambers 111d, and the flow area of ​​the first flow channel 111 at the first flow chamber 111d is greater than the flow area at the first extension chamber 111c.

[0067] Specifically, when the refrigerant in the first flow channel 111 flows through the first flow cavity 111d, some of the refrigerant can flow out of the first flow channel 111 from the first heat exchange inlet / outlet 111b corresponding to the position of the first flow cavity 111d, and some of the refrigerant can flow toward the first extension cavity 111c adjacent to the first flow cavity 111d.

[0068] Since the flow area of ​​the first flow channel 111 at the first flow cavity 111d is greater than the flow area at the first extension cavity 111c, when the refrigerant flows through the first flow cavity 111d, the refrigerant can flow at a relatively gentle speed, which is conducive to the refrigerant passing through the first heat exchange inlet and outlet 111b stably, and greatly avoids the refrigerant causing strong impact on the first heat exchange inlet and outlet 111b, which is beneficial to improving the service life of the manifold 100.

[0069] Reference Figure 6 In some specific embodiments, the cavity wall surface of the first extension cavity 111c is a first cylindrical surface 111c1, and the cavity wall surface of the first flow cavity 111d is a first spherical surface 111d1. The radius of curvature of the first spherical surface 111d1 is greater than the radius of curvature of the first cylindrical surface 111c1 adjacent to it.

[0070] When the refrigerant flows through the first extension cavity 111c, the first cylindrical surface 111c1 can guide the refrigerant, allowing it to flow smoothly along the axial direction of the first cylindrical surface 111c1 to the first flow cavity 111d. When the refrigerant flows through the first flow cavity 111d, since the radius of curvature of the first spherical surface 111d1 is greater than the radius of curvature of the adjacent first cylindrical surface 111c1, the flow velocity of the refrigerant will slow down here, which is beneficial to the flow of the refrigerant.

[0071] In the above technical solution, by setting the cavity wall surface of the first extension cavity 111c as a first cylindrical surface 111c1 and the cavity wall surface of the first flow cavity 111d as a first spherical surface 111d1, on the one hand, the refrigerant can be subjected to uniform force at all points on the cavity wall of the first extension cavity 111c and the cavity wall of the first flow cavity 111d, thereby improving the structural reliability of the cavity walls of the first extension cavity 111c and the first flow cavity 111d. On the other hand, the flow resistance of the refrigerant can be reduced, and energy loss can be avoided.

[0072] Reference Figures 4-6 In some embodiments, the flow area of ​​the plurality of first extension cavities 111c remains constant and / or gradually decreases along the extension direction of the first flow channel 111.

[0073] For example, along the extension direction of the first flow channel 111, the flow area of ​​the multiple first extension cavities 111c remains unchanged, which allows the refrigerant in the first extension cavity 111c to flow at a relatively constant speed, ensuring that the heat exchanger 200 can operate normally.

[0074] For example, along the extension direction of the first flow channel 111, the flow area of ​​the plurality of first extension cavities 111c gradually decreases, which can accelerate the flow rate of the refrigerant in the first extension cavity 111c, thereby accelerating the flow rate of the refrigerant into the heat exchanger 200 and improving the heat exchange rate of the heat exchanger 200.

[0075] Of course, it is also possible that along the extension direction of the first flow channel 111, the partial flow area of ​​the multiple first extension cavities 111c remains unchanged, while the partial flow area of ​​the multiple first extension cavities 111c gradually decreases.

[0076] In other embodiments, the flow area of ​​the plurality of first extension cavities 111c remains constant and / or gradually increases along the extension direction of the first flow channel 111.

[0077] For example, along the extension direction of the first flow channel 111, the flow area of ​​the multiple first extension cavities 111c gradually increases, which can slow down the flow rate of the refrigerant in the first extension cavity 111c, so that the refrigerant flowing into the heat exchanger 200 can exchange heat with the heat exchanger 200 for a longer time, thereby improving the heat exchange effect of the heat exchanger.

[0078] Of course, it is also possible that along the extension direction of the first flow channel 111, the partial flow area of ​​the multiple first extension cavities 111c remains unchanged, while the partial flow area of ​​the multiple first extension cavities 111c gradually increases.

[0079] Reference Figures 4-6 In some examples, the second flow channel 112 includes a second extension cavity 112b and a second flow cavity 112c, with multiple second extension cavities 112b and multiple second flow cavities 112c arranged alternately and connected.

[0080] Among them, the positions of multiple second heat exchange inlets and outlets 112a correspond one-to-one with and are connected to multiple second flow chambers 112c, and the flow area of ​​the second flow channel 112 at the second flow chamber 112c is greater than the flow area at the second extension chamber 112b.

[0081] Specifically, the refrigerant that has completed heat exchange in the heat exchanger 200 can flow out of the heat exchanger 200 from multiple second heat exchange inlets and outlets 112a and converge into the second flow channel 112. When the refrigerant flowing out of the heat exchanger 200 has an excessive flow velocity, the second flow cavity 112c with a larger flow area can buffer the high-speed refrigerant, which can reduce its flow velocity to a certain extent, allowing it to flow more smoothly in the second flow cavity 112c. This avoids the high-speed refrigerant from causing a large impact on the second flow channel 112, which could lead to damage to the second flow channel 112 and improve the service life of the manifold 100.

[0082] Reference Figure 6 In some specific examples, the cavity wall surface of the second extension cavity 112b is a second cylindrical surface 112b1, and the cavity wall surface of the second flow cavity 112c is a second spherical surface 112c1. The radius of curvature of the second spherical surface 112c1 is greater than the radius of curvature of the adjacent second cylindrical surface 112b1.

[0083] When the refrigerant flows into the second flow channel 112 from the second heat exchange inlet / outlet 112a, it is dispersed and flows under the guidance of the second spherical surface 112c1, so that it can flow to the second extension cavity 112b adjacent to the second flow cavity 112c. When the refrigerant flows to the second extension cavity 112b, the second cylindrical surface 112b1 can guide the refrigerant, so that the refrigerant can flow smoothly along the axial direction of the second cylindrical surface 112b1.

[0084] In the above technical solution, by making the cavity wall surface of the second extension cavity 112b a second cylindrical surface 112b1 and the cavity wall surface of the second flow cavity 112c a second spherical surface 112c1, on the one hand, the refrigerant can be subjected to uniform force at all points on the cavity wall of the second extension cavity 112b and the cavity wall of the second flow cavity 112c, thereby improving the structural reliability of the cavity walls of the second extension cavity 112b and the second flow cavity 112c. On the other hand, it can reduce the flow resistance of the refrigerant and avoid energy loss.

[0085] The radii of curvature of the first sphere 111d1 and the second sphere 112c1 can be changed according to performance requirements.

[0086] In some embodiments, along the extension direction of the second flow channel 112, the flow area of ​​the plurality of second extension cavities 112b remains constant and / or gradually decreases.

[0087] For example, along the extension direction of the second flow channel 112, the flow area of ​​the multiple second extension cavities 112b remains unchanged, which allows the refrigerant in the second extension cavity 112b to flow at a relatively constant speed, ensuring that the heat exchanger 200 can operate normally.

[0088] For example, along the extension direction of the second flow channel 112, the flow area of ​​the plurality of second extension cavities 112b gradually decreases, which can accelerate the flow rate of the refrigerant in the second extension cavity 112b, thereby increasing the heat exchange rate of the heat exchanger 200.

[0089] Alternatively, along the extension direction of the second flow channel 112, the partial flow area of ​​the multiple second extension cavities 112b remains unchanged, while the partial flow area of ​​the multiple second extension cavities 112b gradually decreases.

[0090] In other embodiments, the flow area of ​​the plurality of second extension cavities 112b remains constant and / or gradually increases along the extension direction of the second flow channel 112.

[0091] For example, along the extension direction of the second flow channel 112, the flow area of ​​the plurality of second extension cavities 112b gradually increases, which can slow down the flow rate of the refrigerant in the second extension cavity 112b, thereby allowing the refrigerant to exchange heat with the heat exchanger 200 for a longer time and improving the heat exchange effect of the heat exchanger 200.

[0092] Of course, it is also possible that along the extension direction of the second flow channel 112, the partial flow area of ​​the multiple second extension cavities 112b remains unchanged, while the partial flow area of ​​the multiple second extension cavities 112b gradually increases.

[0093] Reference Figure 2 and Figure 4In some embodiments, the second substrate 12 and the first substrate 11 further define a third flow channel 113, one end of the third flow channel 113 is connected to one end of the second flow channel 112 and the two are set at an angle, and the third flow channel 113 also has a second total inlet and outlet 113a, which is connected to the second flow channel 112.

[0094] In other words, the second total inlet / outlet 113a can function as both a total inlet and a total outlet. When the second total inlet / outlet 113a functions as a total inlet, refrigerant can flow from the second total inlet / outlet 113a into the third flow channel 113 and the second flow channel 112; when the second total inlet / outlet 113a functions as a total outlet, refrigerant in the second flow channel 112 can flow from the second total inlet / outlet 113a into the second flow channel 112.

[0095] In the above technical solution, by setting the third flow channel 113 at an angle to the second flow channel 112, on the one hand, the heat exchange tube 211 of the heat exchange body 21 can be matched so that it avoids the nearby heat exchange tube 211. On the other hand, based on the fixed length of the manifold 10, the space at one end of the second flow channel 112 can be effectively utilized, which is conducive to improving the space utilization rate of the manifold 10 and reducing the material cost of the manifold 10.

[0096] Reference Figure 2 and Figure 7 In some specific embodiments, the orientation of the second total inlet / outlet 113a is the same as that of the first total inlet / outlet 111a, and the orientation of the second total inlet / outlet 113a is the same as, opposite to, or at a first included angle to the orientation of the second heat exchange inlet / outlet 112a, wherein the first included angle is 60°-120°.

[0097] For example, the orientation of the second total inlet / outlet 113a is the same as that of the first total inlet / outlet 111a, and the orientation of the second total inlet / outlet 113a is the same as that of the second heat exchange inlet / outlet 112a, so that the manifold 100 only needs to be connected to the heat exchanger 200 from one side. On the one hand, it can save space, and on the other hand, it can facilitate installation and maintenance, and maintenance personnel only need to operate from one side.

[0098] For example, the orientation of the second total inlet / outlet 113a is the same as that of the first total inlet / outlet 111a, and the orientation of the second total inlet / outlet 113a is opposite to that of the second heat exchange inlet / outlet 112a. This allows the manifold 100 to be connected between different heat exchange sections of the heat exchanger 200, or between two heat exchangers 200, thereby adapting to different usage scenarios and improving space utilization.

[0099] For example, the orientation of the second total inlet / outlet 113a is the same as that of the first total inlet / outlet 111a, and the orientation of the second total inlet / outlet 113a forms a first angle with the orientation of the second heat exchange inlet / outlet 112a, which is 60°-120°. This allows the manifold 100 to be easily connected to different heat exchange sections of the heat exchanger 200 according to the structure of the heat exchanger 200, or to be easily connected to the two heat exchangers 200 according to their arrangement. This allows it to adapt to different usage scenarios and improve space utilization.

[0100] In other embodiments, the orientation of the second total inlet / outlet 113a is at a second angle to the orientation of the first total inlet / outlet 111a, the second angle being 60°-120°, and the orientation of the second total inlet / outlet 113a is the same as, opposite to, or at a first angle to the orientation of the second heat exchange inlet / outlet 112a, the first angle being 60°-120°.

[0101] For example, the orientation of the second total inlet / outlet 113a is at a second angle to the orientation of the first total inlet / outlet 111a, the second angle being 60°-120°, and the orientation of the second total inlet / outlet 113a is the same as the orientation of the second heat exchange inlet / outlet 112a.

[0102] For example, the orientation of the second total inlet / outlet 113a is at a second angle to the orientation of the first total inlet / outlet 111a, the second angle being 60°-120°, and the orientation of the second total inlet / outlet 113a is opposite to the orientation of the second heat exchange inlet / outlet 112a.

[0103] For example, the orientation of the second total inlet / outlet 113a forms a second angle with the orientation of the first total inlet / outlet 111a, the second angle being 60°-120°, and the orientation of the second total inlet / outlet 113a forms a first angle with the orientation of the second heat exchange inlet / outlet 112a, the first angle being 60°-120°.

[0104] This configuration allows the manifold 100 to be easily connected to different heat exchange sections of the heat exchanger 200, depending on the structure of the heat exchanger 200, or to be easily connected to the two heat exchangers 200 according to their arrangement. This adapts to different usage scenarios and improves space utilization.

[0105] Reference Figure 5 and Figure 7 In some embodiments, the manifold 100 further includes a plurality of first connecting pipes 13 and a plurality of second connecting pipes 14, wherein the plurality of first connecting pipes 13 are connected to a plurality of first heat exchange inlets and outlets 111b in a one-to-one correspondence, and the plurality of second connecting pipes 14 are connected to a plurality of second heat exchange inlets and outlets 112a in a one-to-one correspondence.

[0106] Specifically, if the first flow channel 111 is used as the input flow channel and the second flow channel 112 is used as the output flow channel, the refrigerant in the first flow channel 111 can flow out through multiple first heat exchange inlets and outlets 111b. The refrigerant flowing through the first heat exchange inlets and outlets 111b can flow into the heat exchanger 200 through the first connecting pipe 13. After heat exchange, the refrigerant can flow to the second heat exchange inlet and outlet 112a through the second connecting pipe 14, and then flow into the second flow channel 112 through the second heat exchange inlet and outlet 112a.

[0107] If the first flow channel 111 is used as an output flow channel and the second flow channel 112 is used as an input flow channel, the refrigerant in the second flow channel 112 can flow out through multiple second heat exchange inlets and outlets 112a. The refrigerant flowing through the second heat exchange inlets and outlets 112a can flow into the heat exchanger 200 through the second connecting pipe 14. After heat exchange, the refrigerant can flow to the first heat exchange inlet and outlet 111b through the first connecting pipe 13, and then flow into the first flow channel 111 through the first heat exchange inlet and outlet 111b.

[0108] Among them, a plurality of first connecting pipes 13 and a plurality of second connecting pipes 14 are connected to the same side of the thickness direction of the manifold 10, and all extend along the thickness direction of the manifold 10.

[0109] Therefore, by connecting multiple first connecting pipes 13 and multiple second connecting pipes 14 on the same side of the thickness direction of the manifold 10, the layout of the manifold 100 can be simplified and space can be saved, so that the manifold 100 only needs to be connected to the heat exchanger 200 from one side. On the other hand, the assembly and disassembly operations only need to be carried out on one side, which greatly improves the assembly and disassembly efficiency.

[0110] The following is for reference. Figures 8-10 A heat exchanger 200 according to an embodiment of the present utility model is described.

[0111] Reference Figures 8-10 The heat exchanger 200 according to an embodiment of the present utility model includes a heat exchange body 21 and a flow collector 100. The heat exchange body 21 has a plurality of heat exchange channels 210. The flow collector 100 is the flow collector 100 of the heat exchanger according to any of the above embodiments. The flow collector 100 is disposed at one end of the heat exchange body 21. The first flow channel 111 is connected to one end of the plurality of heat exchange channels 210, and the second flow channel 112 is connected to the other end of the plurality of heat exchange channels 210.

[0112] If the first flow channel 111 is used as the input flow channel and the second flow channel 112 is used as the output flow channel, when the heat exchanger 200 is running, the refrigerant in the first flow channel 111 can be diverted from multiple first heat exchange inlets and outlets 111b and enter multiple heat exchange channels 210 of the heat exchange body 21. After heat exchange in the heat exchange body 21, the refrigerant in the multiple heat exchange channels 210 converges into the second flow channel 112 through multiple second heat exchange inlets and outlets 112a, thereby completing the heat exchange.

[0113] If the first flow channel 111 is used as the output flow channel and the second flow channel 112 is used as the input flow channel, when the heat exchanger 200 is running, the refrigerant in the second flow channel 112 can be diverted from multiple second heat exchange inlets and outlets 112a and enter multiple heat exchange channels 210 of the heat exchange body 21. After heat exchange in the heat exchange body 21, the refrigerant in the multiple heat exchange channels 210 converges to the first flow channel 111 through multiple first heat exchange inlets and outlets 111b, thereby completing the heat exchange.

[0114] According to the embodiment of the present utility model, by setting the heat exchanger 200 to include the heat exchange body 21 and the flow collector 100 of the above embodiment, the number of parts of the heat exchanger 200 can be reduced, the structure of the heat exchanger 200 can be simplified, the structure can be made more compact, the assembly difficulty of the heat exchanger 200 can be reduced, the production efficiency can be improved, and the production cost can be reduced.

[0115] The following describes an air conditioning system according to an embodiment of the present invention.

[0116] The air conditioning system (not shown in the figure) according to an embodiment of the present invention includes a compressor (not shown in the figure), an evaporator (not shown in the figure), and a condenser (not shown in the figure). The compressor has an exhaust port and a return port. The evaporator is connected to the return port. The condenser is a heat exchanger 200 according to the above embodiment. The first flow channel 111 is connected to the exhaust port through the first total inlet and outlet 111a. The second flow channel 112 is connected to the evaporator through the second total inlet and outlet 113a and a throttling element (not shown in the figure).

[0117] When the air conditioning system is working, the compressor can compress the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant is distributed to different parts of the condenser through the first flow channel 111. The condenser can condense the high-temperature, high-pressure gaseous refrigerant into a high-pressure liquid refrigerant, which flows into the second flow channel 112. After being throttled and depressurized by the throttling device, it forms a low-pressure liquid refrigerant. The low-pressure liquid refrigerant enters the evaporator, where it can vaporize into a low-temperature, low-pressure gaseous refrigerant. The low-pressure gaseous refrigerant flows back to the compressor from the return port, and the cycle repeats.

[0118] According to the embodiment of the present utility model, by adopting the above-mentioned heat exchanger 200, the production difficulty of the air conditioning system can be reduced, the production efficiency can be improved, and the production cost can be reduced.

[0119] like Figure 10 As shown, in some embodiments, the air conditioning system also includes a four-way valve 300, and the first total inlet / outlet 111a and a pipe interface of the four-way valve 300 can be connected by a refrigerant pipe.
