Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making inventive efforts shall fall within the protection scope of the present invention. 【0021】 The terms used in the embodiments of the present invention are only for the purpose of explaining specific embodiments and are not intended to limit the present invention. The singular forms of "a kind", "the above-mentioned" and "the said" used in the embodiments of the present invention and the appended patent claims are also intended to include plural forms unless the context clearly indicates otherwise. 【0022】 It should be understood that the term "and / or" used in this specification only explains the relationship of related objects, and there may be three types of relationships. For example, A and / or B can represent the following relationships, and there are three situations where A exists alone, A and B exist simultaneously, and B exists alone. Also, the symbol " / " in this specification generally indicates that the related objects before and after are in an "or" relationship. 【0023】 As shown in Figures 1-3, an embodiment of the present invention provides an energy storage converter 100. The energy storage converter 100 includes a substrate 1 and at least one heat pipe group 4, wherein the substrate 1 has an electronic component 2 on one side and a heat sink 3 on the other side, and the heat pipe group 4 is provided on the side of the heat sink 3 that is close to the substrate 1 and is connected to the heat sink 3. Here, the heat pipe group 4 includes at least one first heat pipe 41, the first heat pipe 41 includes a main body portion 411 and an extension portion 412, the extension portion 412 is located along the longitudinal direction of the main body portion 411 on at least one side of the main body portion 411 and communicates with the main body portion 411, the extension portion 412 and the main body portion 411 form an angle α, and the ratio of the length of the main body portion 411 to the length of the extension portion 412 is 4.3 to 4.5. 【0024】 During the operation of the energy storage converter 100, the electronic component 2 releases a large amount of heat, which is transferred to the substrate 1. The substrate 1 then transfers the heat to the heat sink 3 via the first heat pipe 41, and the heat sink 3 dissipates the thermal energy. Here, the substrate 1 may be a copper substrate 1 having good thermal conductivity. The substrate 1 may be connected to the heat sink 3 by fasteners such as screws (not shown), and the first heat pipe 41 may be fitted into the heat sink 3. The first heat pipe 41 has good thermal conductivity and can achieve rapid heat conduction, and can quickly conduct the heat transferred from the substrate 1 to the heat sink 3, which is advantageous in improving the heat dissipation effect of the heat sink 3. The heat pipe group 4 may have a plurality of first heat pipes 41. Specifically, the longitudinal direction of the main body portion 411 of the first heat pipe 41 may be parallel to the short direction Y of the heat sink 3, and the short direction of the main body portion 411 may be parallel to the longitudinal direction X of the heat sink 3. The extension portion 412 communicates with the main body portion 411 and is provided at an inclination with respect to the main body portion 411; that is, the main body portion 411 and the extension portion 412 have different extension directions. Specifically, the angle α between the extension portion 412 and the main body portion 411 may be between approximately 120° and 150°. This allows the main body portion 411 and the extension portion 412 to conduct heat in different directions, which is advantageous for increasing the heat conduction range of the first heat pipe 41. In addition, the lengths of the main body portion 411 and the extension portion 412 are different, with the length of the main body portion 411 being greater than the length of the extension portion 412. Here, the length of the main body portion 411 is the dimension in the extension direction of the main body portion 411, and similarly, the length of the extension portion 412 is the dimension in the extension direction of the extension portion 412. Specifically, the ratio of the length of the main body portion 411 to the length of the extension portion 412 is 4.3, 4.33, 4.35, 4.37, 4.4, 4.43, 4.45, 4.47, and 4.5, and of course, other values ​​within the above range are also acceptable. 【0025】 In embodiments of the present invention, the first heat pipe 41 can play a role in rapidly conducting heat, and by laying the first heat pipe 41 in or within the heat sink 3, heat emitted from the electronic component 2 can be quickly and effectively transferred to the heat sink 3. Such a heat dissipation method is highly reliable, allows heat to be dissipated by the heat sink 3 in a timely manner, reduces the possibility of the electronic component 2 failing due to its own temperature becoming too high, and is advantageous in maintaining the normal operation of the energy storage converter 100. Herein, regarding the first heat pipe 41, conventional heat pipes on heat sinks usually have a small heat conduction area and low heat conduction efficiency, which tends to affect the heat dissipation performance of the heat sink and further tends to affect the normal operation of the entire energy storage converter. In an embodiment of the present invention, the first heat pipe 41 has a main body portion 411 and an extended portion 412. By providing the extended portion 412, the heat conduction area of ​​the first heat pipe 41 can be effectively increased, which is advantageous in improving the heat conduction efficiency of the first heat pipe 41 so as to improve the heat conduction effect of the first heat pipe 41, and is also advantageous in improving the heat dissipation performance of the heat sink 3. At the same time, the main body portion 411 and the extended portion 412 form an angle, allowing the first heat pipe 41 to conduct heat in different directions, which improves the heat conduction range of the first heat pipe 41 and allows heat to be uniformly distributed by the heat sink 3. That is, it is advantageous in improving the temperature uniformity of the heat sink 3, and is also advantageous in further improving the heat dissipation effect of the heat sink 3. As described above, by providing the first heat pipe 41, the heat sink 3 can have reliable heat dissipation performance, which is advantageous in improving the heat dissipation efficiency of the heat sink 3, and reduces the possibility of high-temperature failures occurring in the electronic components 2, thereby improving the overall reliability of the energy storage converter 100, enabling the energy storage converter 100 to operate normally and stably. 【0026】 As shown in Figure 1, a fan 5 may be provided inside the energy storage converter 100. Operating the fan 5 is advantageous in further improving the heat dissipation effect of the heat sink 3, thereby improving the overall heat dissipation performance of the energy storage converter 100 to ensure normal and stable operation of the energy storage converter 100. 【0027】 As shown in Figure 3, in one possible embodiment, the first heat pipe 41 includes one extension 412, which is located at one end of the main body 411 along the longitudinal direction of the main body 411, and the angle α between the main body 411 and the extension 412 is 130° to 140°. 【0028】 The extension portion 412 may be provided at the upper end of the main body portion 411 or at the lower end of the main body portion 411, where the angle α between the main body portion 411 and the extension portion 412 may be 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, or 140°, and of course, it may be any other value within the above range. Preferably, the angle α is 135°. 【0029】 By defining the angular range of the angle between the main body portion 411 and the extension portion 412, it is advantageous to improve the structural stability of the first heat pipe 41 itself, to improve the reliability of the first heat pipe 41, to extend the service life of the first heat pipe 41, to improve the reliability of the heat sink 3, and also advantageous for the processing and production of the first heat pipe 41. 【0030】 In the above embodiment, the extension portion 412 is provided at the end of the main body portion 411, and in some other embodiments, the extension portion may be provided at other locations on the main body portion, for example, at the midpoint of the main body portion. The position of the extension portion 412 may be designed in correspondence with the actual heat source location in the energy storage converter 100 (for example, the location of the electronic component 2) in order to improve the heat dissipation effect of the heat sink 3. 【0031】 As shown in Figures 4 and 5, in one possible embodiment, the first heat pipe 41 includes two extensions 412, the two extensions 412 located at both ends of the main body 411 along the longitudinal direction of the main body 411, the two extensions 412 extending toward the same side of the main body 411 along the short direction of the main body 411, or the two extensions 412 extending toward both sides of the main body 411. 【0032】 The two extensions 412 may be provided along the longitudinal direction of the main body 411, at the upper and lower ends of the main body 411, respectively. The two extensions 412 may extend simultaneously in the same direction along the short direction of the main body 411, so that the first heat pipe 41 has a substantially "C" shape. Alternatively, the two extensions 412 may extend along the short direction of the main body 411, on both sides of the main body 411, that is, the extension directions of the two extensions 412 may be opposite, so that the first heat pipe 41 has a substantially "Z" shape. 【0033】 Providing two extended portions 412 is advantageous in further increasing the heat conduction area of ​​the first heat pipe 41, improving the reliability of the first heat pipe 41, improving the heat conduction efficiency of the first heat pipe 41, and also allowing heat to be uniformly distributed by the heat sink 3, which is advantageous in improving the temperature uniformity of the heat sink 3 and improving the heat dissipation effect of the heat sink 3. Here, the direction of extension of the two extended portions 412 may be determined based on the actual position of the heat source in order to improve the heat dissipation effect of the heat sink 3. 【0034】 As shown in Figure 5, in one possible embodiment, the two extensions 412 have extension directions parallel to each other. 【0035】 In the two extended portions 412, the angle between one extended portion 412 and the main body portion 411 is α1, and the angle between the other extended portion 412 and the main body portion 411 is α2. The angles between angle α1 and angle α2 are the same, meaning the two extended portions 412 may be arranged parallel to each other. This design is advantageous for improving the structural stability of the first heat pipe 41 itself and for extending the service life of the first heat pipe 41. On the other hand, if the heat pipe group 4 has multiple first heat pipes 41, the above design is also advantageous for realizing a parallel arrangement of multiple first heat pipes 41 to further improve the heat conduction effect of the heat pipe group 4. 【0036】 As shown in Figures 6 and 7, in one possible embodiment, the extension 412 includes at least a first extension segment 412a and a second extension segment 412b, the second extension segment 412b being located on the side of the first extension segment 412a away from the main body 411 and communicating with the main body 411 via the first extension segment 412a, and the first extension segment 412a and the second extension segment 412b forming an angle β. 【0037】 The first extending segment 412a and the second extending segment 412b are connected to each other to form a bent structure, and the lengths of the first extending segment 412a and the second extending segment 412b may be the same or different. Here, the extending directions of the first extending segment 412a and the second extending segment 412b may be different, specifically, the main body 411, the first extending segment 412a and the second extending segment 412b may all extend in different directions, or the extending directions of the main body 411 and the second extending segment 412b may be the same, and one end of the first extending segment 412a is in communication with the main body 411 and the other end is in communication with the second extending segment 412b and forms corresponding angles with the main body 411 and the second extending segment 412b. 【0038】 This design is advantageous in that it allows for an even larger heat conduction area of ​​the first heat pipe 41, enables the first heat pipe 41 to conduct heat in multiple directions, further improves the heat conduction effect of the first heat pipe 41, and further improves the heat dissipation effect of the heat sink 3. 【0039】 In one possible embodiment, the heat pipe group 4 includes a plurality of first heat pipes 41, which are spaced apart along the longitudinal direction X or the short direction Y of the heat sink, or the plurality of first heat pipes 41 are arranged continuously. 【0040】 The number, arrangement direction, and arrangement method of the first heat pipes 41 can all be designed according to the actual conditions and distribution location of the heat source. Specifically, in the heat pipe group 4, the multiple first heat pipes 41 may be arranged at uniform intervals, or they may be arranged at uneven intervals. For example, the distance between adjacent first heat pipes 41 may gradually increase or decrease towards the edge of the heat sink 3. Of course, the multiple first heat pipes 41 may also be arranged continuously. In some other embodiments, some of the first heat pipes 41 in the heat pipe group 4 may be arranged at intervals, while others may be arranged continuously. 【0041】 Multiple heat pipe groups 4 may be provided on the heat sink 3, where the number of first heat pipes 41 in each heat pipe group 4 may be the same or different. Some of the first heat pipes 41 in the heat pipe group 4 may be arranged along the longitudinal direction X of the heat sink 3, and other first heat pipes 41 in the heat pipe group 4 may be arranged along the short direction Y of the heat sink 3. Furthermore, some of the first heat pipes 41 in the heat pipe group 4 may be arranged at intervals, and the first heat pipes 41 in other heat pipe groups 4 may be arranged continuously. 【0042】 By designing the arrangement of the first heat pipe 41, the heat pipe group 4 can be better adapted to the heat source, which is advantageous in improving the overall heat conduction effect of the heat pipe group 4, enabling stable and normal operation of the energy storage converter 100, as well as improving the heat dissipation effect of the heat sink 3 and improving its heat dissipation efficiency. 【0043】 As shown in Figures 2 and 8, in one possible embodiment, the heat pipe group 4 further includes at least one second heat pipe 42, the extending direction of the second heat pipe 42 is the same as the extending direction of the main body 411, and the length of the second heat pipe 42 is less than the length of the first heat pipe 41. 【0044】 The heat pipe group 4 includes both a first heat pipe 41 and a second heat pipe 42, and similarly, the second heat pipe 42 can also achieve rapid heat conduction. In the heat pipe group 4, there may be one or more second heat pipes 42, and the length of the second heat pipe 42 may be the same as the length of the main body 411 of the first heat pipe 41. However, since the first heat pipe 41 has an extension 412, the length of the second heat pipe 42 is smaller than the length of the first heat pipe 41. 【0045】 Because the second heat pipe 42 has small dimensions, its production cost is low, and using the second heat pipe 42 is advantageous in ensuring the overall heat conduction effect of the heat pipe group 4, while simultaneously reducing the operating cost of the heat pipe group 4, and further advantageous in reducing the overall production cost of the energy storage converter 100. On the other hand, the heat pipe group 4 is equipped with two types of heat pipes with different dimensional specifications, and this design is advantageous in improving the overall reliability of the heat pipe group 4, allowing the heat pipe group 4 to be better suited to the heat source, and is advantageous in improving the heat dissipation effect of the heat sink 3. 【0046】 In one possible embodiment, the ratio of the length of the second heat pipe 42 to the length of the first heat pipe 41 is 0.81 to 0.84. 【0047】 Specifically, the ratio of the length of the second heat pipe 42 to the length of the first heat pipe 41 is 0.81, 0.82, 0.83, or 0.84, and of course, other values ​​within the above range are also acceptable. Further defining the length of the second heat pipe 42 is advantageous for improving the heat conduction effect of the second heat pipe 42, advantageous for improving the heat conduction effect of the entire heat pipe group 4, and advantageous for reducing the overall operating cost of the heat pipe group 4. 【0048】 As shown in Figure 8, in one possible embodiment, in the heat pipe group 4, the first heat pipe 41 and the second heat pipe 42 are arranged along the longitudinal direction X or the transverse direction Y of the heat sink 3, where the second heat pipe 42 is located between two adjacent first heat pipes 41. 【0049】 The number of second heat pipes 42 may be multiple. Specifically, multiple second heat pipes 42 may be located between two adjacent first heat pipes 41 and be arranged continuously or spaced apart. More specifically, the heat pipe group 4 may have four first heat pipes 41 and two second heat pipes 42. The four first heat pipes 41 are grouped in pairs, and each pair is provided on either side of the two second heat pipes 42, so that the heat pipe group 4 has a symmetrical structure. 【0050】 By defining the arrangement of the first heat pipe 41 and the second heat pipe 42, the entire heat pipe group 4 can be better adapted to the heat source, which is advantageous for improving the heat conduction effect of the entire heat pipe group 4, and further advantageous for improving the heat dissipation effect of the heat sink 3. 【0051】 In one possible embodiment, in the heat pipe group 4, the first heat pipe 41 and the second heat pipe 42 are arranged alternately along the longitudinal direction X or the short direction Y of the heat sink 3. 【0052】 The number of first heat pipes 41 and second heat pipes 42 in the heat pipe group 4 may be multiple, and they are arranged alternately. Here, adjacent first heat pipes 41 and second heat pipes 42 may be spaced apart or arranged continuously. 【0053】 This design is advantageous in achieving a uniform arrangement of the first heat pipe 41 and the second heat pipe 42 in the heat sink 3, improving the reliability of the heat pipe group 4, enhancing the overall heat conduction effect of the heat pipe group 4, enabling efficient and uniform heat transfer to the heat sink 3 by the heat pipe group 4, and further improving the heat dissipation effect and heat dissipation efficiency of the heat sink 3. 【0054】 As shown in Figure 8, in one possible embodiment, the energy storage converter 100 includes a plurality of heat pipe groups 4, which are arranged at intervals along the longitudinal direction X or the short direction Y of the heat sink 3, or the plurality of heat pipe groups 4 are arranged continuously. 【0055】 The number of heat pipe groups 4 may be two, three, four, or more, and the multiple heat pipe groups 4 may be arranged along the longitudinal direction X of the heat sink 3, or along the short direction Y of the heat sink 3. Here, the multiple heat pipe groups 4 may be arranged at intervals, and specifically, the distance between adjacent heat pipe groups 4 may be determined based on the location distribution of the heat sources. Of course, the multiple heat pipe groups 4 may also be arranged continuously. 【0056】 By providing multiple heat pipe groups 4, the heat conduction area can be further increased, allowing heat to be uniformly transferred by the heat sink 31. This is advantageous in further improving the heat dissipation effect of the heat sink 3 and in achieving normal and stable operation of the energy storage converter 100. 【0057】 As shown in Figures 2 and 8, in one possible embodiment, the heat sink 3 includes a heat sink plate 31 and heat sink fins 32, the heat pipe group 4 is provided on the heat sink plate 31, and the heat sink fins 32 are located on the side of the heat sink plate 31 away from the heat pipe group 4 and are connected to the heat sink plate 31. 【0058】 The heat sink 31 may be in contact with the substrate 1, and each heat pipe in the heat pipe group 4 is fitted into the heat sink 31. The other side of the heat sink 31 is fixedly connected to a plurality of heat dissipation fins 32, where two adjacent heat dissipation fins 32 are spaced apart. The heat dissipation fins 32 can make sufficient contact with the air, allowing heat to be dissipated into the air more quickly and efficiently. Therefore, providing the heat dissipation fins 32 is advantageous in further improving the overall heat dissipation efficiency of the heat sink 3, thereby improving the reliability of the heat sink 3. 【0059】 As shown in Figure 9, in some other embodiments, a sealing bar 6 may be attached to the heat sink 31. Referring to Figure 1, when the substrate 1 is connected to the heat sink 3, the sealing bar 6 can contact the substrate 1, improving the sealing between the heat sink 3 and the substrate 1, thereby achieving a sealed connection between the substrate 1 and the heat sink 3, which is advantageous for improving the heat dissipation effect of the heat sink 3. Here, a mounting groove (not shown) may be provided in the heat sink 31, and the sealing bar 6 may be attached to the mounting groove, with both ends of the sealing bar 6 engaged in the mounting groove, so that the front and rear ends of the sealing bar 6 are connected to form a sealed ring-shaped structure. The heat pipe group 4 is located within this ring-shaped structure, that is, the sealing bar 6 can surround each heat pipe group 4, and a certain distance is secured in advance between the sealing bar 6 and the heat pipe group 4. Designing it in this way reduces the possibility of interference between the sealing bar 6 and the heat pipe group 4, and is convenient for assembling them with the heat sink 31. At the same time, the heat pipe group 4 transfers heat to the seal bar 6, reducing the possibility that the temperature of the seal bar 6 itself will rise and prevent it from operating normally, which is advantageous for improving the service life of the seal bar 6. 【0060】 The foregoing describes only preferred embodiments of the present invention and does not limit it; to those skilled in the art, the present invention is subject to various modifications and changes. Any modifications, substitutions with equivalents, improvements, etc., made within the spirit and principles of the present invention should be within the scope of protection of the present invention.
