Description

Technical Field

[0001] This application relates to the field of heat dissipation device technology, and in particular to a heat dissipation device and an energy storage converter. Background Technology

[0002] In the process of accelerating the achievement of dual-carbon goals and building a new power system, energy storage technology is gradually becoming one of the key technologies supporting the stable operation of the new power system and optimizing resource allocation. Among them, the energy storage converter (PCS) is a key device in the energy storage system, mainly used to control the charging and discharging process of the battery and to perform AC-DC conversion. During the operation of the energy storage system, the PCS will generate a lot of heat. Therefore, the heat dissipation system is crucial to ensuring the normal operation of the PCS and extending its service life. As an important part of the heat dissipation system, the fan undertakes the important task of heat dissipation, cooling and maintaining the operating temperature.

[0003] However, the inventors believe that the aforementioned technologies have the following drawbacks: In traditional heat dissipation systems, the maintenance of fans is usually cumbersome and the efficiency of disassembling and assembling fans is low. If the fan is installed in a poor location, maintenance personnel may need to spend more time and effort to disassemble and assemble the fan, which further leads to low maintenance efficiency. This not only increases maintenance costs but may also affect the normal operation and reliability of the equipment. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings showing multiple embodiments according to this application. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort will fall within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing specific embodiments only and is not intended to limit this application; the terms "comprising," "including," "having," "containing," etc., in the description, claims, and accompanying drawings of this application are open-ended terms. Therefore, "comprising," "including," or "having" refers to, for example, a method or apparatus having one or more steps or elements, but is not limited to having only these one or more elements. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this application, it should be understood that the terms "center", "lateral", "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0039] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0040] One or more embodiments of this application disclose a heat dissipation device, see reference Figures 1 to 11 The device includes a support frame 1, a fixing frame 2, and a fan 3. The support frame 1 has a heat dissipation channel 11. The fixing frame 2 is adapted to restrict the fan 3 to one side of the heat dissipation channel 11. The diameter of the heat dissipation channel 11 needs to be matched to the size of the fan 3's air inlet and outlet ducts. The fixing frame 2 is provided with a connecting part 21. The support frame 1 is provided with a connecting port 12 and a locking device 4 around the heat dissipation channel 11. The connecting part 21 is adapted to cooperate with the connecting port 12 to connect the fixing frame 2 and the support frame 1. The locking device 4 is adapted to contact and cooperate with the connecting part 21 to prevent the connecting part 21 from disengaging from the connecting port 12. The design of the locking device 4 allows the disassembly and assembly connection between the support frame 1 and the fixing frame 2 to be restricted by a mechanical structure. Since the use of common fasteners is reduced or eliminated, the disassembly and assembly of the fixing frame 2 is reduced, thereby improving the efficiency of fan 3 maintenance and replacement.

[0041] like Figures 1 to 5 In the illustrated embodiment, the connection port 12 includes a first connection channel 121 and a second connection channel 122, and the connection portion 21 is adapted to run along a first direction (refer to...). Figure 3 The vertical direction) passes through the first connecting channel 121, and the connecting part 21 is adapted to be along the second direction (refer to the vertical direction) through the first connecting channel 121. Figure 3 horizontal direction or Figure 4 The horizontal direction) enters the second connecting channel 122 from the first connecting channel 121 and abuts against the fixing frame 2 in the first direction. The locking device 4 is adapted to restrict the movement of the connecting part 21 in the second connecting channel 122 in the second direction.

[0042] like Figure 1 , 2 In the embodiments shown in 4 and 5, the locker 4 includes a connecting end 41 and a locking end 42. The connecting end 41 is rotatably connected to the support frame 1. The locking end 42 can be locked by rotating the connecting end 41 towards the connecting part 21 or unlocked by rotating it away from the connecting part 21. The locking end 42 is provided with a locking groove 421, which is at least adapted to abut against and limit the connecting part 21 on both sides in the second direction, thereby restricting the connecting part 21 from moving along the connecting part 21. Figure 4 Horizontal movement within.

[0043] In addition, the locking device 4 is connected to the support frame 1 through the connecting end 41, which can reduce the probability of the locking device 4 being lost, improve the stability of use, and reduce the occurrence of parts falling into the equipment and affecting the normal operation of the equipment.

[0044] like Figure 4 and 5 In the embodiment shown, a transition slope 4211 is provided on the side of the slot 421 near the connecting end 41. The transition slope 4211 gradually slopes towards the connecting end 41 from the opening of the slot 421, which can reduce structural interference before the slot 421 and the connecting part 21 cooperate and abut against the limit, that is, it can enable the connecting part 21 to be properly embedded in the slot 421.

[0045] like Figure 4 and 5 In the embodiment shown, the connecting end 41 and the second connecting channel 122 are located on both sides of the first connecting channel 121. It can be understood that since the connecting end 41 and the support frame 1 are rotatably connected, even if the locker 4 rotates, this design can increase the difficulty for the connecting part 21 to disengage from the slot 421, thereby improving the locking stability of the locker 4.

[0046] like Figure 5 In the illustrated embodiment, the front end of the connecting part 21 is a bent structure 211, so that the connecting part 21 is suitable for engaging with the support frame 1 in the second connecting channel 122. The height of the first connecting channel 121 is not less than the height of the bent structure 211, and the height of the second connecting channel 122 is less than the height of the bent structure 211. The width of the first connecting channel 121 is not less than the width of the bent structure 211, and the height of the second connecting channel 122 is less than the height of the first connecting channel 121, ensuring smooth engagement between the connecting part 21 and the connecting port 12 and reducing structural interference.

[0047] like Figure 6 and 7 In the illustrated embodiment, the connection port 12 includes a first connection channel 121, and the connection portion 21 is adapted to run along a first direction (refer to...). Figure 3 (In the vertical direction) through the first connecting channel 121, the locking device 4 is adapted to restrict the connecting part 21 from disengaging from the first connecting channel 121.

[0048] like Figure 6 and 7 In the embodiment shown, the locker 4 includes a connecting end 41 and a locking end 42. The connecting end 41 is rotatably connected to the support frame 1, and the locking end 42 is adapted to abut against the connecting part 21 in a first direction at the first connecting channel 121 to restrict the connecting part 21 from disengaging from the first connecting channel 121.

[0049] like Figure 7In the embodiment shown, the front end of the connecting part 21 is a bent structure 211, so that the connecting part 21 is suitable for engaging with the locking end 42 at the first connecting channel 121. The height of the first connecting channel 121 is not less than the height of the bent structure 211, and the width of the first connecting channel 121 is not less than the width of the bent structure 211, so as to ensure smooth engagement between the connecting part 21 and the connecting port 12 and reduce structural interference.

[0050] like Figure 6 and 7 In the embodiment shown, the locker further includes an elastic element 43, which is adapted to restrict the locking end 42 away from the connecting portion 21.

[0051] In some embodiments, the elastic element 43 is a torsion spring.

[0052] It is understandable that if the bending structure 211 at the front end of the connecting part 21 is set to bend in the direction of the fan 3, it can also prevent the fan 3 from separating from the fixed frame 2, improve the stability of the connection between the fan 3 and the fixed frame 2 before the fixed frame 2 is connected to the support frame 1, thereby reducing the installation difficulty.

[0053] like Figure 1 and 8 In the embodiment shown, the fixing frame 2 includes a fixing ring 22 and multiple fixing arms 23. The fixing ring 22 is in contact with the first side of the fan 3, and the fixing arms 23 extend along the periphery of the fan 3 to the plane where the second side of the fan 3 is located. The fixing ring 22 and the fixing arms 23 can restrict the fan 3 and effectively prevent the fan 3 from detaching from the fixing frame 2. At least one fixing arm 23 is provided with a connecting part 21, which protrudes from the plane where the second side of the fan 3 is located. The fixing frame 2 can make the fan 3 fit against the support frame 1, and the fixing frame 2 can be connected to the support frame 1 through the connecting part 21 protruding from the second side of the fan 3, thereby realizing a stable connection between the fixing frame 2, the fan 3 and the support frame 1.

[0054] In some embodiments, a fixing arm 23 is provided on each side of the fan 3 to enable the fan 3 to achieve higher installation stability.

[0055] In some embodiments, one or more connection ports 12 are provided around the heat dissipation channel 11, and a connecting part 21 is provided on one or more fixing arms 23 along the first direction of the fixing frame 2, and the connecting part 21 and the connection port 12 are connected in a one-to-one manner.

[0056] like Figure 1 and Figure 2 In the embodiment shown, the fixing frame 2 is along the first direction (reference) Figure 2The fixed arms 23 on both sides of the vertical direction are provided with connecting parts 21. The multiple connecting parts 21 are connected to the connecting port 12, which can improve the connection strength between the fixed frame 2 and the support frame 1, increase the connection stability, improve the fixing effect of the fixed frame 2 and the support frame 1 on the fan 3, reduce the vibration of the fan 3 during operation, and thus improve the stability of the fan 3 during operation.

[0057] The locking device 4 can be installed on one side of one of the connection ports 12, or on both sides of the connection ports 12, to lock the corresponding connection parts 21.

[0058] It is understandable that, since the fan 3 in this application has a rectangular structure, the mounting bracket 2 is along the first direction (refer to...) Figure 2 The two fixed arms 23 on both sides of the vertical direction are parallel to each other, so the connection action between the connecting part 21 on the two fixed arms 23 and the connecting port 12 can be consistent, which can reduce the difficulty of structural design and processing, and also facilitate the installation of the connecting part 21 and the connecting port 12.

[0059] like Figure 8 In the embodiment shown, the fixing frame 2 is provided with a contact portion 231 on at least part of the fixing arm 23. When the fixing frame 2 and the support frame 1 are connected, the contact portion 231 is adapted to fit against the surface of the support frame 1 to improve the connection stability between the fixing frame 2 and the support frame 1 and reduce the generation of shaking.

[0060] like Figure 1 , 2 In the embodiments shown in Figure 9, the support frame 1 has at least one wiring section 13 on the side away from the mounting of the fixed frame 2.

[0061] In at least one embodiment, the wiring section 13 is disposed on both sides of the fan 3 mounting position to guide and constrain the cable leading out from the fan 3.

[0062] In some embodiments, the cable can be connected and fixed to the cable routing section 13 by cable ties.

[0063] In some embodiments, the aperture of the wiring portion 13 is at least larger than the width of the cable, so that the cable can pass through directly.

[0064] like Figure 1 , 9 In the embodiments shown in 10 and 11, one end of the support frame 1 is provided with a detachable handle 14. The handle 14 is detachably connected to the support frame 1, and different specifications of handle 14 and different specifications of support frame 1 can be selected for matching connection to adapt to different specifications of machines. At the same time, the support frame 1 can be replaced to change the heat dissipation specifications within the same machine, which has higher applicability.

[0065] like Figure 1 , 9 In the embodiments shown in 10 and 11, the handle 14 is an embedded structure, which makes full use of the spare space on the support frame 1, improves the structural compactness, and makes the space occupied by the heat dissipation device on the outside of the chassis smaller after installation.

[0066] like Figure 10 and 11 In the embodiment shown, the heat dissipation device includes a radiator 5, which is arranged in the airflow path of the fan 3. The radiator 5 is provided with multiple heat dissipation fins, which are arranged along the airflow path of the fan 3. The radiator 5 is used to conduct and absorb heat inside the housing 6. Then, when the airflow of the fan 3 passes through the gaps between the heat dissipation fins, it can carry away the heat absorbed by the radiator 5, thereby achieving a high-efficiency heat dissipation effect.

[0067] It is worth noting that the radiator 5 and the support frame 1 can be arranged separately, which makes the structural arrangement of the heat dissipation device inside the machine more flexible and less prone to structural interference. At the same time, since the radiator 5 has strong stability and is not easily damaged, the separate arrangement of the radiator 5 and the support frame 1 can reduce the number of structures that need to be disassembled during maintenance, thereby reducing the difficulty of maintenance.

[0068] One or more embodiments of this application disclose an energy storage converter, see reference Figures 10 to 11 The device includes a housing 6 and a heat dissipation device according to any of the above embodiments. A maintenance port 61 is provided on one side of the housing 6. The heat dissipation device can be easily disassembled and maintained through the maintenance port 61, reducing or eliminating the need to open the housing 6 structure of the energy storage converter, thereby improving maintenance efficiency and reducing the probability of machine damage during maintenance. A guide rail 62 connected to the maintenance port 61 is provided inside the housing 6. The heat dissipation device is inserted through the maintenance port 61 and fixed inside the housing 6 along the guide rail 62. The guide rail 62 can guide the disassembly and assembly of the heat dissipation device, improving the stability and safety of the heat dissipation device installation operation. It can further reduce the probability of damaging the internal structure of the housing 6 during maintenance when it is difficult to observe the internal structure of the housing 6.

[0069] In some embodiments, the support frame 1 is adapted to the guide rail frame 62, and the support frame 1 can slide along the guide rail frame 62.

[0070] In some embodiments, the opening size of the maintenance port 61 is smaller than the size of the embedded handle 14 of the heat dissipation device, and the periphery of the embedded handle 14 can be connected and fixed to the housing 6 by a universal fastener.

[0071] In some embodiments, a male and female connector for the fan 3 can be designed and arranged next to the maintenance port 61 inside the chassis. The male and female connector can also be designed to be detached from the maintenance port 61 to facilitate connection or disconnection operations when maintaining or replacing the fan 3.

[0072] like Figure 10 and 11 In the embodiment shown, the guide rail frame 62 is a double guide rail structure arranged vertically opposite each other, and a cover 621 is connected between the double guide rail structures. The cover 621 can improve the overall structural stability of the guide rail frame 62. The cover 621 is provided with a heat dissipation port 6211, which is used to cooperate with the heat dissipation channel 11 of the heat dissipation device to ensure that the airflow of the fan 3 can pass through smoothly.

[0073] When the heat dissipation device of this application is applied to equipment such as energy storage converters, in some cases, it is also possible to maintain and replace the fan 3 without shutting down the equipment, thereby reducing economic losses.

[0074] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
