Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and more specifically, to a heat exchanger and energy storage system. Background Technology

[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters of the process to meet the requirements of the process conditions. It is also one of the main devices for improving energy utilization efficiency.

[0003] Currently, energy storage systems typically include plate heat exchangers and microchannel heat exchangers.

The microchannel heat exchanger carries refrigerant, enabling heat exchange between the refrigerant and the indoor air to lower the indoor air temperature and thus achieve dehumidification. However, these two heat exchanges require two separate heat exchangers, resulting in low integration. Summary of the Invention

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0050] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0051] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] Please refer to Figures 1 to 3 as well as Figure 12 and Figure 13This embodiment provides a heat exchanger, which includes two manifolds 10 and a connecting pipe 20; both ends of the connecting pipe 20 are connected to the two manifolds 10 respectively; each manifold 10 has a first compartment 1111 and a second compartment 1112 that are isolated from each other; the connecting pipe 20 has a first heat exchange channel 21 and a second heat exchange channel 22, and the connecting pipe 20 also has a first heat exchange section 25, the two ends of the first heat exchange channel 21 are respectively connected to the first compartment 1111 of the two manifolds 10, and the two ends of the second heat exchange channel 22 are respectively connected to the first compartment 1111 of the two manifolds 10. The two-part chamber 1112 is connected; the first heat exchange section 25 is located between the first heat exchange channel 21 and the second heat exchange channel 22, and is connected to the walls of the first heat exchange channel 21 and the second heat exchange channel 22 respectively. The corresponding wall of the second heat exchange channel is connected to the outer wall 26 of the connecting pipe. The outer wall 26 of the connecting pipe can directly contact the ambient air, thereby realizing heat exchange between the fluid in the second heat exchange channel and the ambient air. The outer wall 26 of the connecting pipe can also indirectly contact the air, such as when it is connected to the heat exchange fins 30, and then contacts the ambient air through the heat exchange fins 30. This heat exchanger and energy storage system can improve the integration of the heat exchanger and reduce the space occupation.

[0053] It should be noted that, please refer to Figure 2 and Figure 12 The heat exchanger provided in this application includes two manifolds 10 and a connecting pipe 20, wherein the two manifolds 10 are located at opposite ends of the connecting pipe 20, and the two manifolds 10 are respectively connected to opposite ends of the connecting pipe 20.

[0054] Each current collector assembly 10 has a first sub-cavity 1111 and a second sub-cavity 1112, wherein the first sub-cavity 1111 and the second sub-cavity 1112 are isolated from each other, that is, the first sub-cavity 1111 and the second sub-cavity 1112 are not interconnected. It should be noted that this application does not limit the isolation method of the first sub-cavity 1111 and the second sub-cavity 1112. Those skilled in the art can determine it themselves. For example, a separate component can be provided in the current collector assembly 10 to divide the inner cavity of the current collector assembly 10 into two chambers, which serve as the first sub-cavity 1111 and the second sub-cavity 1112, respectively; or an internal rib integrally formed therewith can be provided in the current collector assembly 10, thereby dividing the inner cavity of the current collector assembly 10 into two chambers, which serve as the first sub-cavity 1111 and the second sub-cavity 1112, respectively.

[0055] The connecting pipe 20 has a first heat exchange channel 21 and a second heat exchange channel 22. In this embodiment, the first heat exchange channel 21 and the second heat exchange channel 22 are not interconnected. The first heat exchange channel 21 connects the first sub-cavities 1111 of the two manifolds 10, and the second heat exchange channel 22 connects the second sub-cavities 1112 of the two manifolds 10. That is, one end of the first heat exchange channel 21 is connected to the first sub-cavity 1111 of one manifold 10, and the other end is connected to the first sub-cavity 1111 of the other manifold 10. One end of the second heat exchange channel 22 is connected to the second sub-cavity 1112 of one manifold 10, and the other end is connected to the second sub-cavity 1112 of the other manifold 10.

[0056] Furthermore, the first heat exchange channel 21 and the second heat exchange channel 22 are arranged adjacent to each other. The first heat exchange channel 21 may be located outside the connecting pipe 20, or the second heat exchange channel 22 may be located outside the connecting pipe 20. This application does not limit this and can determine it according to actual needs. For ease of understanding and explanation, the following description and the accompanying drawings will use the example of the second heat exchange channel 22 being located outside the connecting pipe 20 and the first heat exchange channel 21 being located inside the connecting pipe 20.

[0057] A first fluid flows through the first chamber 1111 of the two manifolds 10, and a second fluid flows through the second chamber 1112 of the two manifolds 10. The connecting pipe 20 is provided with a first heat exchange channel 21 and a second heat exchange channel 22, so that the heat exchange channel located on the outside can exchange heat with the heat exchange channel located on the inside, and can also exchange heat with the air.

[0058] The second heat exchange channel 22 is disposed on the outer periphery of the first heat exchange channel 21. The first heat exchange section 25 is located between the first heat exchange channel 21 and the second heat exchange channel 22, and is connected to the walls of the first heat exchange channel 21 and the second heat exchange channel 22, respectively. The corresponding wall of the second heat exchange channel 22 is connected to the outer wall 26 of the connecting pipe. In this way, heat exchange between the first heat exchange channel 21 and the second heat exchange channel 22 can be achieved through the first heat exchange section 25, and heat exchange with air can be achieved through the second heat exchange channel 22.

[0059] In summary, the heat exchanger provided in this application includes two manifolds 10 and a connecting pipe 20; both ends of the connecting pipe 20 are connected to the two manifolds 10 respectively; each manifold 10 has a first compartment 1111 and a second compartment 1112 that are isolated from each other; the connecting pipe 20 has a first heat exchange channel 21 and a second heat exchange channel 22, and the connecting pipe 20 also has a first heat exchange section 25, the two ends of the first heat exchange channel 21 are connected to the first compartment 1111 of the two manifolds 10 respectively, and the two ends of the second heat exchange channel 22 are connected to the second compartment 1112 of the two manifolds 10 respectively; the first heat exchange section 25 is located between the first heat exchange channel 21 and the second heat exchange channel 22, and is connected to the wall of the first heat exchange channel 21 and the wall of the second heat exchange channel 22 respectively, and the corresponding wall of the second heat exchange channel 22 is connected to the outer wall 26 of the connecting pipe. This application provides a first heat exchange channel 21 and a second heat exchange channel 22 on the connecting pipe 20, and a first heat exchange section 25 is provided between the first heat exchange channel 21 and the second heat exchange channel 22. In this way, the outer heat exchange channel can exchange heat with the inner heat exchange channel through the first heat exchange section 25, and can also exchange heat with air. Thus, compared to the existing microchannel heat exchangers where a single channel can only exchange heat with air, the design of this application is equivalent to inheriting the features of both microchannel heat exchangers and plate heat exchangers, improving system integration, simplifying assembly, and reducing space occupation.

[0060] To facilitate the formation of the first sub-cavity 1111 and the second sub-cavity 1112 within the current collector assembly 10, please refer to... Figure 2 and Figure 3 ,or Figure 12 and Figure 13 Optionally, the current collection assembly 10 includes a current collection pipe 11 having a receiving cavity 111 and a partition plate 12 disposed in the receiving cavity 111; the partition plate 12 is used to divide the receiving cavity 111 of the current collection pipe 11 into a first sub-cavity 1111 and a second sub-cavity 1112.

[0061] The aforementioned partition plate 12 can be integrally formed with the manifold 11, or they can be two separate components; this application does not impose any restrictions. When the partition plate 12 and the manifold 11 are two separate components, the opposite sides of the partition plate 12 along the third direction c can be welded to the inner wall of the manifold 11.

[0062] It should be noted that the aforementioned partition plate 12 divides the accommodating cavity 111 into a first sub-cavity 1111 and a second sub-cavity 1112. The volume of the first sub-cavity 1111 and the second sub-cavity 1112 is not limited in this application and can be set to be the same or different as needed.

[0063] Furthermore, the aforementioned partition plate 12 should not affect the connection between the first compartment 1111 and the first heat exchange channel 21, or between the second compartment 1112 and the second heat exchange channel 22. For example, clearance holes can be provided on the partition plate 12 accordingly.

[0064] Please refer to Figure 5 Optionally, the current collection assembly 10 also includes a cover 13 and a base 14; the cover 13 is located at one end of the current collection pipe 11, and the base 14 is located at the other end of the current collection pipe 11. The cover 13 and the base 14 are respectively provided with limiting grooves, and the opposite ends of the partition plate 12 are respectively inserted into the limiting groove 131 of the cover and the limiting groove 141 of the base.

[0065] In other words, the cover 13 and the base 14 are located on opposite sides of the partition plate 12, and the limiting groove 131 of the cover and the limiting groove 141 of the base can be inserted and engaged with the opposite sides of the partition plate 12, so that the cover 13 and the base 14 can limit the partition plate 12.

[0066] Additionally, it should be noted that, in order to shield and seal the first cavity 1111 and the second cavity 1112 to prevent foreign objects from entering, the cover 13 should cover the top of the first cavity 1111 and the second cavity 1112, and the base 14 should be located at the bottom of the first cavity 1111 and the second cavity 1112. The orthographic projections of the cover 13 and the base 14 along the first direction a should cover the first cavity 1111 and the second cavity 1112.

[0067] Of course, to facilitate liquid inflow, two through holes can be provided on the base 14, one of which is connected to the first compartment 1111 and the other is connected to the second compartment 1112. The two through holes on the base 14 of one flow collector assembly 10 serve as two liquid inlets, and the two through holes on the base 14 of the other flow collector assembly 10 serve as two liquid outlets.

[0068] Please refer to Figure 2 and Figure 12 Optionally, the arrangement direction of the two manifolds 11 is the same as the arrangement direction of the first sub-cavity 1111 and the second sub-cavity 1112. That is, the two manifolds 11 are arranged side by side and spaced apart along the second direction b, and the first sub-cavity 1111 and the second sub-cavity 1112 are arranged side by side along the second direction b. In this way, the liquid in the first heat exchange channel 21 and the liquid in the second heat exchange channel 22 can increase the contact area and improve the heat exchange efficiency during the heat exchange process.

[0069] Alternatively, please refer to Figure 1 , Figure 2 and Figure 12The connecting pipe 20 includes multiple pipes, which are arranged along a first direction a, perpendicular to the arrangement direction of the two current collectors 10. That is, the two current collectors 10 are arranged along a second direction b, and the multiple connecting pipes 20 are arranged along the first direction a.

[0070] The specific number of the aforementioned connecting pipes 20 is not limited in this application and can be set as needed.

[0071] To further increase the contact area between the connecting pipe 20 and the air, thereby improving the heat exchange effect between the connecting pipe 20 and the air, optionally, heat exchange fins 30 can be provided between two adjacent connecting pipes 20 along the first direction, and the heat exchange fins 30 are in contact with the outer wall 26 of the connecting pipe.

[0072] In this way, the contact area between the wall of the second heat exchange channel 22 and the air can be increased by using heat exchange fins.

[0073] Of course, heat exchange fins 30 can be provided between two adjacent connecting pipes 20, or heat exchange fins 30 can be provided on both adjacent sides of any connecting pipe 20.

[0074] To further improve the heat exchange effect between the second heat exchange channel 22 and the first heat exchange channel 21, the second heat exchange channel 22 may optionally be arranged around the outer periphery of the first heat exchange channel 21.

[0075] It should be noted that when the second heat exchange channel 22 is disposed on the outer periphery of the first heat exchange channel 21, it can take several forms. For example, in one form, the second heat exchange channel 22 can be multiple heat exchange holes 221, which are arranged around the outer periphery of the first heat exchange channel 21; in another form, the second heat exchange channel 22 can be an annular channel. These two forms will be introduced and explained below.

[0076] First Embodiment

[0077] In this embodiment, the second heat exchange channel 22 includes a plurality of heat exchange holes 221, which are arranged around the outer periphery of the first heat exchange channel 21. Please refer to... Figures 2 to 11 As shown.

[0078] The second heat exchange channel 22 includes multiple heat exchange holes 221, please refer to Figure 7 and Figure 8 As shown, multiple heat exchange holes 221 are arranged around the first heat exchange channel 21. That is, the first heat exchange channel 21 is located inside the connecting pipe 20, and the multiple heat exchange holes 221 are located outside the first heat exchange channel 21. The multiple heat exchange holes 221 form the second heat exchange channel 22.

[0079] The first heat exchange section 25 is located between the walls of the plurality of heat exchange holes 221 and the wall of the first heat exchange channel 21, and is connected to both the wall of the first heat exchange channel 21 and the walls of the plurality of heat exchange holes 221. In this way, the wall of each heat exchange hole 221 can exchange heat with the wall of the first heat exchange channel 21.

[0080] Please refer to Figures 9 to 11 Optionally, the manifold 11 is provided with a first insertion port 112, and the partition plate 12 is provided with a first connecting channel 121 communicating with the first partition chamber 1111; the opposite ends of the connecting pipe 20 pass through the first insertion port 112 of the two manifolds 11 and extend into the second partition chamber 1112 of the corresponding manifold 11, and the opposite ends of the first heat exchange channel 21 are respectively connected to the first connecting channel 121 of the two partition plates 12.

[0081] The first insertion port 112 is connected to the second sub-cavity 1112. The first insertion port 112 is provided so that the connecting tube 20 can be inserted from the first insertion port 112 and extend into the second sub-cavity 1112.

[0082] One end of the first connecting channel 121 on the partition plate 12 is connected to the first sub-cavity 1111, and the other end is connected to the first heat exchange channel 21 of the connecting pipe 20 inserted into the second sub-cavity 1112. In this way, the two opposite ends of the first heat exchange channel 21 of the connecting pipe 20 can be connected to the two first sub-cavities 1111 respectively through the two first connecting channels 121.

[0083] Alternatively, please refer to Figure 10 and Figure 11 The partition plate 12 includes a first body 122, a first connecting flange 123, and two first limiting platforms 124 disposed on opposite sides of the first connecting flange 123. The first connecting flange 123 is disposed on the side of the first body 122 facing the second cavity 1112. The first connecting channel 121 is disposed through the first body 122 and the first connecting flange 123. The length of the first connecting flange 123 along the second direction b is greater than the length of the first limiting platform 124 along the second direction b. The opposite ends of the connecting pipe 20 are respectively sleeved on the outer periphery of the first connecting flange 123 of the two partition plates 12, and the two sides of the ends of the connecting pipe 20 respectively abut against the two first limiting platforms 124. The second direction b is the same as the arrangement direction of the two current collection components 10.

[0084] That is, the first connecting flange 123 and the two first limiting platforms 124 are respectively protruding on the first body 122, and the two first limiting platforms 124 are respectively located at opposite ends of the first connecting flange 123. It should be noted that the first connecting flange 123 and the two first limiting platforms 124 may include multiple sets, and the specific number of sets can be determined according to the number of connecting pipes 20, which will not be elaborated in this application.

[0085] The first connecting channel 121 is configured to pass through the first body 122 and the first connecting flange 123, as shown in the figure. Figure 6 As shown, the partition plate 12 can connect the first compartment 1111 and the first heat exchange channel 21 through the first connecting channel 121.

[0086] Furthermore, in this embodiment, the length of the first connecting flange 123 along the second direction b is greater than the length of the first limiting platform 124 along the second direction b; that is, the height of the first connecting flange 123 on the first body 122 is greater than the height of the first limiting platform 124 on the first body 122. Thus, when the end of the connecting pipe 20 is fitted onto the outer periphery of the first connecting flange 123 of the partition plate 12, the first heat exchange channel 21 inside the connecting pipe 20 can communicate with the first compartment 1111 through the first connecting channel 121. The end of the connecting pipe 20 can also abut against the first limiting platform 124, such as... Figure 5 and Figure 6 As shown, this prevents the end of the connecting pipe 20 from contacting the side wall of the partition plate 12 near the second compartment 1112, thereby avoiding the side wall of the partition plate 12 from blocking the second heat exchange channel 22, allowing for quick installation of the connecting pipe 20, and preventing the second heat exchange channel 22 from being blocked.

[0087] To prevent the connecting pipe 20 from dividing the second cavity 1112 into multiple parts arranged along the first direction a, optionally, as follows: Figure 4 and Figure 6 As shown, the connecting pipe 20 has gaps between its two opposite sides along the third direction c and the inner wall of the second cavity 1112, and the third direction c is perpendicular to the second direction b.

[0088] In this embodiment, the first direction a, the second direction b, and the third direction c are perpendicular to each other. This arrangement allows the liquid in the second chambers 1112 of the two flow collectors 10 to flow vertically (i.e., the liquid in the second chambers 1112 can flow along the first direction a).

[0089] Second Embodiment

[0090] In this embodiment, the second heat exchange channel 22 is an annular channel surrounding the first heat exchange channel 21. Please refer to... Figures 12 to 19 As shown.

[0091] Specifically, please refer to Figure 16 and Figure 17 The connecting pipe 20 includes a first branch pipe 23 and a second branch pipe 24 sleeved on the outer periphery of the first branch pipe 23. The inner cavity of the first branch pipe 23 forms a first heat exchange channel 21, and the gap between the inner wall of the second branch pipe 24 and the outer wall of the first branch pipe 23 forms a second heat exchange channel 22.

[0092] In this embodiment, the length of the first branch pipe 23 is greater than the length of the second branch pipe 24, and the second branch pipe 24 is located in the middle position of the second branch pipe 24. That is, the connecting pipe 20 including the first branch pipe 23 and the second branch pipe 24 is symmetrically arranged, such as... Figure 5 As shown.

[0093] In this embodiment, the first heat exchange section 25 is located between the inside of the second branch pipe 24 and the outer wall of the first branch pipe 23, and is connected to the wall of the first heat exchange channel 21 and the outer wall of the first branch pipe 23, respectively. In this way, the second heat exchange channel of the second branch pipe 24 can exchange heat with the outer wall of the first branch pipe 23.

[0094] Please refer to Figures 12 to 15 Optionally, the manifold 11 is provided with a second insertion port 113 and a second limiting platform 114 located at the second insertion port 113, and the partition plate 12 is provided with a second connecting channel 125 communicating with the first partition chamber 1111; the opposite ends of the first branch pipe 23 respectively pass through the second insertion port 113 of the two manifolds 11 and extend into the second partition chamber 1112 of the corresponding manifold 11, and the opposite ends of the first heat exchange channel 21 are respectively connected to the second connecting channel 125 of the two partition plates 12; the opposite ends of the second branch pipe 24 respectively extend into the second insertion port 113 of the two manifolds 11 and abut against the corresponding limiting platform.

[0095] The aforementioned second insertion interface 113 is used for inserting the connecting pipe 20. The end of the second branch pipe 24 of the connecting pipe 20 abuts against the second limiting platform 114. It should be noted that the second heat exchange channel 22 formed by the gap between the second branch pipe 24 and the first branch pipe 23 is not blocked by the second limiting platform 114. That is, the second limiting platform 114 can be arranged in a ring shape. When arranged in a ring shape, the volume of the inner cavity of the second limiting platform 114 is larger than the volume of the first branch pipe 23, so that the first branch pipe 23 can extend into the inner cavity of the second limiting platform 114 without contacting the inner wall of the second limiting platform 114, thereby avoiding blocking the second heat exchange channel 22. The second limiting platform 114 can also be a protrusion connected to the second insertion interface 113. The protrusion is also set with the premise of not blocking the second heat exchange channel 22.

[0096] Alternatively, please refer to Figure 18 and Figure 19 The partition plate 12 includes a second body 126 and a second connecting flange 127 disposed on the side of the second body 126 facing the second cavity 1112; the second connecting channel 125 is disposed through the second body 126 and the second connecting flange 127, and the opposite ends of the first branch pipe 23 are respectively sleeved on the outer periphery of the second connecting flange 127 of the two partition plates 12.

[0097] By setting the second body 126 and the second connecting flange 127, as shown in the following figure... Figure 12 and Figure 13 As shown, the connecting pipe 20 is inserted into the second insertion port 113, and the second branch pipe 24 abuts against the second limiting platform 114. The first branch pipe 23 extends into the second compartment 1112 and is sleeved on the outer periphery of the second connecting flange 127 of the partition plate 12. In this way, the liquid in the two first compartments 1111 can communicate with the first heat exchange channel 21 of the first branch pipe 23 through the second connecting channel 125 of their respective partition plates, and the liquid in the two second compartments 1112 can communicate with the gap between the first branch pipe 23 and the second branch pipe 24 (i.e., the second heat exchange channel 22).

[0098] In another aspect, the present invention provides an energy storage system including the aforementioned heat exchanger. The specific structure and technical effects of the heat exchanger have been described in detail above and will not be repeated here. By incorporating the aforementioned heat exchanger, the energy storage system allows the outer heat exchange channel of the two heat exchange channels to exchange heat with the inner heat exchange channel on one hand, and with the air on the other. Thus, compared to the existing microchannel heat exchangers where a single channel can only exchange heat with air, the design of this application essentially combines the features of both microchannel and plate heat exchangers, improving system integration, simplifying assembly, and reducing space requirements.

[0099] The above description is merely an optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0100] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
