[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an electrical device provided in an embodiment of this application.

[0036] like Figure 1 As shown, this application embodiment provides an electrical device 100, which may be, for example, an energy storage device. The electrical device 100 includes a chassis 1000, a refrigeration unit 2000, and an electrical unit 4000.

[0037] The chassis 1000 is the external structure of the electrical equipment 100, a box structure with an internal cavity formed by multiple enclosing panels. In the electrical equipment 100, such as the aforementioned cooling unit 2000 and electrical unit 4000, they can be directly or indirectly installed in the chassis 1000 for integrated assembly. Simultaneously, the chassis 1000 also largely determines the external shape of the electrical equipment 100. In this embodiment, the external shape of the chassis 1000 is not explicitly limited. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements are met. For example, the chassis 1000 can be a triangular prism, cuboid, cylinder, or other three-dimensional structural style.

[0038] The chassis 1000 also houses the electrical unit 4000, which is protected by the chassis 1000 to reduce the impact of external moisture, dust, and other contaminants. The specific type of electrical unit 4000 is related to the specific type of electrical equipment 100 and is not explicitly limited here. Electrical unit 4000 can be a PCB board, copper busbar, energy storage converter, inverter, battery module, DC / DC module, DC / AC module, transformer, etc. For example, when electrical equipment 100 is an energy storage device, electrical unit 4000 can be an energy storage unit, such as a battery compartment.

[0039] The refrigeration unit 2000 includes a refrigerant pipe 2100, which is also located inside the chassis 1000. The chassis 1000 protects the refrigerant pipe 2100, reducing the intrusion of external moisture, dust, etc. A refrigerant flows through the refrigerant pipe 2100, such as water or fluorinated liquid. The refrigerant pipe 2100 provides cooling to the electrical unit 4000 to control its temperature, ensuring that the electrical unit 4000 operates within a relatively optimal temperature range and thus maintaining its performance.

[0040] Here, the embodiments of this application do not limit the specific structural form of the above-mentioned cooling pipe 2100. In practical applications, those skilled in the art can design it according to the layout of the electrical unit 4000 in the chassis 1000, as long as it can meet the requirements of use.

[0041] In one example solution, see [link to example solution]. Figure 1 And can be defined Figure 1 The vertical direction in the middle is vertical. Figure 1 The left and right directions in the text are horizontal. For example... Figure 1 As shown, there can be multiple electrical units 4000; within each electrical unit 4000, multiple electrical units 4000 can be arranged vertically to form a row group; within the chassis 1000, there can be multiple rows groups, and each row group can be arranged horizontally, etc. Based on the above layout of the electrical units 4000, the refrigerant pipe 2100 can include a primary pipe 2100A, a secondary pipe 2100B, and a tertiary pipe 2100C. The primary pipe 2100A is the main pipe, used to introduce or extract refrigerant into the chassis 1000. The secondary pipe 2100B is a branch main pipe, which can be connected to the primary pipe 2100A, used to introduce or extract refrigerant into each row group. The tertiary pipe 2100B is a branch branch pipe, which can be connected to the secondary pipe 2100B, used to introduce or extract refrigerant into each electrical unit 4000 in the row group.

[0042] Please refer to Figures 2-8, Figure 2 for Figure 1 Connection structure diagram of the refrigeration unit and dehumidification unit; Figure 3 for Figure 2 A magnified view of a portion of the image; Figure 4 This is a diagram showing the connection structure of the dehumidification component, the first liquid collection component, and the guide pipe. Figure 5 This is a diagram showing the internal structure of a cylindrical base; Figure 6 This is a schematic diagram of the dehumidification component when the cylindrical base has a split structure. Figure 7 This is a schematic diagram of the dehumidification component when the condenser guide plate is a flat fin. Figure 8 This is a connection structure diagram of the dehumidification component, the first liquid collection component, the exhaust component, and the air guide shell.

[0043] like Figures 2-4 As shown in this embodiment, the electrical device 100 further includes a dehumidification unit 3000. The dehumidification unit 3000 includes a dehumidification component 3100 and a first liquid collection component 3200. The dehumidification component 3100 includes a condensation guide vane 3110, which is mounted on the outside of the refrigerant pipe 2100. The first liquid collection component 3200 is located below the condensation guide vane 3110 and is configured to collect condensate flowing down from the condensation guide vane 3110.

[0044] By adopting the above solution, in this embodiment of the application, the condensation guide plate 3110 is set on the outside of the refrigeration pipe 2100. The low temperature of the refrigeration pipe 2100 itself can be used to trigger the condensation of humid air inside the chassis 1000 on the surface of the condensation guide plate 3110. The condensate formed can be collected by the first liquid collection component 3200, which can largely avoid the condensate dripping onto the electrical unit 4000 and the resulting increase in short circuit risk, increased corrosion of the electrical unit 4000, and many other problems. This can better ensure the normal operation and service life of the electrical equipment 100.

[0045] Furthermore, the condensation guide plate 3110 can also guide the condensate generated directly on the surface of the refrigeration pipe 2100, so that the condensate generated directly on the surface of the refrigeration pipe 2100 can be introduced into the first liquid collection component 3200 at least in part, thereby reducing the harm caused by the condensate to a greater extent.

[0046] In other words, by setting a dehumidification unit 3000 inside the chassis 1000, the low temperature of the refrigeration unit 2000 can be effectively used for dehumidification, thereby reducing the number of dedicated dehumidifiers required, or even eliminating the need for dedicated dehumidifiers. It can also effectively reduce the operating cost of the electrical equipment 100 provided in this embodiment.

[0047] In addition, the arrangement of the dehumidification unit 3000 can increase the contact area between the cooling unit 2000 and the air inside the chassis 1000, which is also beneficial to improving the cooling effect of the cooling unit 2000.

[0048] Here, the embodiments of this application do not limit the specific placement of the dehumidification component 3100 and the first liquid collection component 3200. In practical applications, those skilled in the art can select according to specific needs, as long as the requirements of use are met. For example, taking the aforementioned refrigeration pipe 2100 including a primary pipe 2100A, a secondary pipe 2100B, and a tertiary pipe 2100C as an example, any one of the primary pipe 2100A, the secondary pipe 2100B, and the tertiary pipe 2100C can be provided with the aforementioned dehumidification component 3100 and the first liquid collection component 3200. Considering the arrangement direction of each level of pipe, in a specific example, the aforementioned dehumidification component 3100 and the first liquid collection component 3200 can be located on the vertically extending portion of the secondary pipe 2100B, so that the guiding effect of the condensation guide plate 3110 can be better. For example, the refrigeration pipe 2100 also includes an inlet pipe 2200 and an outlet pipe 2300. The inlet pipe 2200 is used to provide a relatively low-temperature refrigerant to each electrical unit 4000, while the outlet pipe 2300 is used to draw out a relatively high-temperature refrigerant after heat exchange with each electrical unit 4000. Therefore, the surface temperature of the inlet pipe 2200 is relatively lower than that of the outlet pipe 2300. Based on this, the aforementioned dehumidification component 3100 and the first liquid collection component 3200 can also be provided only in the inlet pipe 2200 in order to make full use of the low temperature of the inlet pipe 2200 to achieve condensation of humid air.

[0049] In some implementations, such as Figure 4 As shown, the dehumidification component 3100 may also include a cylindrical base 3120.

[0050] The cylindrical base 3120 can be sleeved on the refrigeration pipe 2100, and the condenser guide vane 3110 can be located on the outer wall surface of the cylindrical base 3120. The condenser guide vane 3110 and the cylindrical base 3120 can be an integrally formed structure, such as integral extrusion molding. Alternatively, the condenser guide vane 3110 and the cylindrical base 3120 can be prepared separately and then assembled by welding or other methods, which is also feasible.

[0051] By adopting the above solution, the dehumidification component 3100 can be installed through the cylindrical base 3120 and the refrigeration pipe 2100, which simplifies the installation process of the dehumidification component 3100 and the refrigeration pipe 2100. In particular, when a dehumidification component 3100 includes at least two condenser guide vanes 3110, by setting the cylindrical base 3120, the integrated arrangement of different condenser guide vanes 3110 can be realized, which can improve the structural compactness of the dehumidification component 3100, and at the same time, it can facilitate the installation between the dehumidification component 3100 and the refrigeration pipe 2100.

[0052] Here, the embodiments of this application do not limit the connection method between the cylindrical base 3120 and the refrigeration pipe 2100. In practical applications, those skilled in the art can configure it according to specific needs, as long as it meets the requirements of use. For example, the cylindrical base 3120 and the refrigeration pipe 2100 can be connected by welding processes such as spot welding. For another example, see... Figure 3 When the dehumidifier 3100 is installed on the secondary pipe 2100B, the tertiary pipe 2100C connected to the secondary pipe 2100B can naturally provide axial restraint for the dehumidifier 3100. In this case, the dehumidifier 3100 can be installed and fixed without the need for other connectors or connection processes, simplifying the installation structure. Alternatively, a stop can be provided on the outer wall of the refrigerant pipe 2100 to provide axial restraint for the dehumidifier 3100.

[0053] In some implementations, such as Figure 5 As shown, the inner wall surface of the cylindrical base 3120 may also be provided with a guide groove 3122.

[0054] The aforementioned guide channel 3122 is used to guide the condensate generated between the cylindrical base 3120 and the refrigeration pipe 2100. This part of the condensate can also be introduced into the first liquid collection component 3200 for collection, thereby reducing the harm caused by condensate to a greater extent.

[0055] Here, the embodiments of this application do not limit the specific structural form of the above-mentioned guide channel 3122. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the above-mentioned guide channel 3122 can be a straight channel extending in a straight direction. As another example, the above-mentioned guide channel 3122 can also be a spiral channel extending in a spiral direction.

[0056] Furthermore, the embodiments of this application do not limit the number of the aforementioned guide channels 3122. In practice, only one guide channel 3122 may be provided, or at least two guide channels 3122 may be provided.

[0057] In some implementations, the cylindrical base 3120 can be a one-piece structure, such as one-piece casting or one-piece extrusion molding.

[0058] In some implementations, such as Figure 6 As shown, the cylindrical base 3120 can be a split structure, including at least two sections 3121. Each section 3121 can have condenser guide vanes 3110 on its outer wall. The sections 3121 can be arranged around the refrigeration pipe 2100, and adjacent sections 3121 can be connected to each other to form a single unit.

[0059] With this design, the cylindrical base 3120 has a split structure. When assembling and connecting the cylindrical base 3120 and the refrigerant pipe 2100, the cylindrical base 3120 is less likely to interfere with the installation of the tertiary piping 2100C, which greatly improves the ease of installation. At the same time, it also allows for easy replacement and maintenance of the cylindrical base 3120 (i.e., the dehumidification component 3100).

[0060] Here, the embodiments of this application do not limit the specific connection method of two adjacent parts 3121. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements of use are met. For example, two adjacent parts 3121 can be connected by bolts. Or, for example, two adjacent parts 3121 can also be connected by cable ties, straps, tape, etc.

[0061] In some implementations, such as Figure 4 and Figure 6 As shown, the condenser guide vane 3110 can be a spiral fin 3111.

[0062] In this implementation, even if the number of condenser guide vanes 3110 is relatively small, for example Figure 4 and Figure 6 Even with only one condenser guide vane 3110, condensation of condensate can be achieved over a relatively large range. In other words, the number of condenser guide vanes 3110 can be reduced, thereby facilitating the connection and fixation of the condenser guide vane 3110 and the cylindrical base 3120.

[0063] It can be seen that, in addition to the aforementioned spiral fins 3111, the condenser guide vanes 3110 can also be configured with other structural forms, as long as they meet the requirements of use. For example, see... Figure 7The condenser guide vane 3110 can also be a flat plate fin 3112. In this case, the number of condenser guide vanes 3110 can be relatively large, and the dehumidification effect can be relatively better. Furthermore, when the generated condensate flows along the flat plate fin 3112 to the first liquid collection component 3200, the flow path is relatively short, and the discharge of condensate can be smoother. For example, the condenser guide vane 3110 can also be combined in various different structural forms. For instance, the condenser guide vane 3110 can also include both the aforementioned spiral fin 3111 and flat plate fin 3112.

[0064] In some implementations, such as Figure 2 and Figure 3 As shown, the dehumidification unit 3000 may further include a second liquid collection component 3300. The first liquid collection component 3200 may be connected to the second liquid collection component 3300, and the condensate in the first liquid collection component 3200 may be introduced into the second liquid collection component 3300 for collection.

[0065] As can be seen, in practical applications, the number of dehumidification components 3100 is relatively large. Therefore, the number of first liquid collection components 3200 used in conjunction with the dehumidification components 3100 is also relatively large. If each first liquid collection component 3200 drains liquid independently, the drainage structure will be relatively complex. Based on this, this embodiment of the application also provides a second liquid collection component 3300, which can be connected to each of the first liquid collection components 3200. The condensate collected by each of the first liquid collection components 3200 can be uniformly introduced into the second liquid collection component 3300, and then drained by the second liquid collection component 3300. In this way, the drainage structure can be relatively simple.

[0066] The dehumidification unit 3000 may also include a guide pipe 3400, and the first liquid collection component 3200 may be connected to the second liquid collection component 3300 through the guide pipe 3400.

[0067] In some designs, each of the first liquid collecting components 3200 can be connected to the second liquid collecting component 3300 via a guide pipe 3400. In this case, each of the first liquid collecting components 3200 can be directly connected to the second liquid collecting component 3300 via a guide pipe 3400.

[0068] In other schemes, some of the first liquid collection components 3200 may be interconnected, and one of these interconnected first liquid collection components 3200 may be connected to the second liquid collection component 3300 through the guide pipe 3400, which is also feasible.

[0069] In a specific example, such as Figure 2 and Figure 3As shown, for each of the first liquid collecting components 3200 installed in the same secondary pipeline 2100B, they can be initially interconnected, and then the lowest first liquid collecting component 3200 can be connected to the second liquid collecting component 3300 via a guide pipe 3400, thus reducing the number of guide pipes 3400 used. It can be seen that in this scheme, except for the lowest first liquid collecting component 3200 which can be directly connected to the second liquid collecting component 3300 via a guide pipe 3400, the other first liquid collecting components 3200 are indirectly connected to the second liquid collecting component 3300 via guide pipes 3400 and guide pipes 3400. The connection methods between the first liquid collecting components 3200 can be varied. For example, a guide hole can be directly opened in the upper first liquid collecting component 3200, and then the condensate in the upper first liquid collecting component 3200 can be guided and dripped into the lower first liquid collecting component 3200 through this guide hole. For example, corresponding pipes can be arranged to connect two adjacent first liquid collection components 3200.

[0070] Combination Figure 2 and Figure 3 The second liquid collecting component 3300 can also be located entirely below the refrigeration unit 2000. In this way, at least part of the refrigeration pipes 2100 can be located directly above the second liquid collecting component 3300, and the condensate formed by the condensation on the surface of these refrigeration pipes 2100 can also be directly dripped into the second liquid collecting component 3300.

[0071] In some implementations, such as Figure 2 and Figure 8 As shown, the refrigeration pipe 2100 may also include an installation pipe section 2110, which may specifically be the aforementioned secondary pipe 2100B. Each dehumidification component 3100 may be installed in the installation pipe section 2110.

[0072] In this embodiment, the dehumidification unit 3000 may further include an exhaust component 3500, which may specifically be a centrifugal fan or the like. The exhaust component 3500 may be disposed at one axial end of the mounting pipe section 2110. The exhaust component 3500 can exhaust air, allowing more humid air inside the chassis 1000 to flow towards the mounting pipe section 2110, and more towards the dehumidification component 3100 disposed in the mounting pipe section 2110, thereby enabling more condensation to occur at the dehumidification component 3100 and enhancing the dehumidification effect of the dehumidification unit 3000. Furthermore, it also helps to improve the uniformity of air humidity in different areas inside the chassis 1000.

[0073] The dehumidification unit 3000 may further include an air guide shell 3600, which may be located on the side of the condenser guide vane 3110 away from the mounting pipe section 2110. The air guide shell 3600 can cooperate with the aforementioned exhaust component 3500 to guide more humid air to the condenser guide vane 3110 of the dehumidification component 3100, thereby condensing it through the dehumidification component 3100.

[0074] In actual assembly, the air guide shell 3600 can be distributed only in a local area along the direction surrounding the mounting pipe section 2110, so as not to affect the flow of humid air inside the chassis 1000 along the air guide shell 3600 to the exhaust component 3500, and the wind resistance can be relatively small. Alternatively, the air guide shell 3600 can also be distributed in various areas along the direction surrounding the mounting pipe section 2110, that is, the air guide shell 3600 can be a cylindrical structure. In this case, the air guide shell 3600 can also be provided with air guide holes 3610 so as to draw humid air inside the chassis 1000 into the interior of the air guide shell 3600.

[0075] The air guide housing 3600 and the dehumidification component 3100 can be configured in a one-to-one correspondence, that is, one dehumidification component 3100 can be configured with one air guide housing 3600. Alternatively, the air guide housing 3600 and the dehumidification component 3100 can also have a one-to-many assembly relationship, that is, one air guide housing 3600 can be used to correspond to multiple dehumidification components 3100.

[0076] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
