[0033] In the related art, energy storage products are usually designed with air cooling. However, air cooling will cause heat dissipation noise, and adding a cooling fan to the energy storage product will occupy the internal space of the energy storage device, and require more assembly parts and processes, which will increase the manufacturing difficulty and cost.

[0034] See also Figure 1 and Figure 2 An energy storage device 100 provided in an embodiment of the utility model includes a housing 10 , a heat conducting member 12 and an inverter 14 .

[0035] The heat conducting member 12 includes a first heat conducting plate 16, which has a first surface 18 and a second surface 20 along the thickness direction. The inverter 14 is installed on the first surface 18. A accommodating space 22 is formed in the shell 10. The heat conducting member 12 and the inverter 14 are accommodated in the accommodating space 22. The second surface 20 is in direct contact with the surface of the shell 10 facing the accommodating space 22. The shell 10 includes a first mounting portion 34, and the heat conducting member 12 includes a second mounting portion. The first mounting portion 34 cooperates with the second mounting portion to limit the position of the heat conducting member 12 in the accommodating space 22 in the first direction and the second direction.

[0036] In the above energy storage device 100, the first surface 18 of the heat conductor 12 is fixedly connected to the inverter 14, and the heat conductor 12 and the inverter 14 are installed in the accommodating space 22 by cooperating with the first mounting portion 34 and the second mounting portion. The installation is simple and reliable, and at the same time, the second surface 20 of the heat conductor 12 is in direct contact with one surface of the shell 10, so that the heat generated by the inverter 14 can be quickly transferred to the shell, and the heat is diluted by convection with the external space, so as to achieve a rapid heat dissipation effect without heat dissipation noise, and at the same time, the installation of the heat dissipation fan is eliminated, saving some assembly processes and manufacturing costs.

[0037] Specifically, energy storage power supplies have a development trend of expanding their use scenarios and increasing power consumption requirements in production and life. As one of the core parts of energy storage power supplies, the inverter should achieve a higher level in compact structure and high-power operation, which makes its thermal management more difficult and challenging.

[0038] The inverter 14 is installed on the heat conductor 12, the shell 10 includes a first mounting portion 34, and the heat conductor 12 includes a second mounting portion. The first mounting portion 34 cooperates with the second mounting portion to limit the position of the heat conductor 12 in the accommodating space 22 in the first direction and the second direction, so that the heat conductor 12 is installed in the accommodating space 22 in the shell 10, and the first surface 18 of the heat conductor 12 directly contacts the inverter 14, and the second surface 20 directly contacts a surface of the shell 10 facing the accommodating space 22. Therefore, the heat conductor 12 can quickly conduct the heat generated by the operation of the inverter 14 to the shell 10, and the shell 10 can achieve rapid heat dissipation by convection with the external space to dilute the heat.

[0039] See also Figure 2 In some embodiments, the heat conducting member 12 further includes a second heat conducting plate 24 , the first heat conducting plate 16 is connected to the second heat conducting plate 24 , the second heat conducting plate 24 has a third surface 26 , and the inverter 14 includes a first heating device 28 , which is in direct contact with the third surface 26 .

[0040] In this way, the contact between the heat generating components in the inverter 14 and the heat conducting member 12 is increased, thereby improving the heat conduction efficiency and the heat dissipation effect.

[0041] Specifically, the inverter 14 includes components with large heat consumption, such as transformers, inductors, and power electronic devices. Therefore, the inverter 14 needs to pay special attention to and strengthen these three components in terms of heat dissipation. Among them, the power electronic devices include insulated gate bipolar insulated gate field effect transistors (IGBTs) and insulated gate field effect transistors (MOS transistors).

[0042] The heat conducting member 12 includes a second heat conducting plate 24 connected to the first heat conducting plate 16. A plurality of insulated gate field effect transistors in the inverter 14 are arranged around the mounting substrate of the inverter 14, and a third surface 26 of the second heat conducting plate 24 along the thickness direction is in direct contact with the first heating element 28.

[0043] Therefore, when the first heating element 28 generates heat, the heat can be directly transferred to the housing 10 through the second heat conducting plate 24 , and the housing 10 and the external space conduct convection to dilute the heat, thereby achieving a rapid heat dissipation effect.

[0044] In one embodiment, the first heating device 28 is an insulated gate field effect transistor.

[0045] In one embodiment, the number of the second heat conducting plates 24 is two. The insulated gate field effect transistors are symmetrically arranged on both sides of the mounting substrate of the inverter 14. The two second heat conducting plates 24 are respectively connected to one edge of the first heat conducting plate 16, so that the heat conducting member 12 forms a U-shaped structure, such as Figure 2 As shown, the two second heat conducting plates 24 are in direct contact with the symmetrically arranged insulated gate field effect transistors, which can accelerate heat conduction, thereby uniformly and quickly conducting and dissipating heat.

[0046] In other embodiments, the number of the second heat conducting plates 24 may be one or more than two, and the number of the second heat conducting plates 24 is not limited herein.

[0047] In some embodiments, the heat conductor 12 has a first mounting hole 30 , the inverter 14 has a second mounting hole (not shown), and the energy storage device 100 further includes a first fastener (not shown), which passes through the first mounting hole 30 and the second mounting hole to fix the inverter 14 on the heat conductor 12 .

[0048] In this way, the inverter 14 and the heat conducting member 12 are fixedly installed by the first fastener, and the installation is simple and convenient.

[0049] Specifically, a first mounting hole 30 is provided on the heat conducting member 12, and a second mounting hole is provided on the inverter 14. The first mounting hole 30 and the second mounting hole are penetrated by a first fastener to fix the inverter 14 and the heat conducting member 12. The connection is stable and firm, and the installation is simple and convenient.

[0050] It should be noted that the first fasteners include but are not limited to bolts, rivets, pins or other types of fasteners.

[0051] In one embodiment, the first mounting hole 30 and the second mounting hole are threaded holes, the first fastener is a bolt, the bolt passes through the threaded hole and is fixed by a nut to achieve a fixed connection between the inverter 14 and the heat conductor 12. The bolt connection is simple, convenient and stable.

[0052] In other embodiments, the fixed connection between the inverter 14 and the heat conducting member 12 may also be performed by welding, gluing or other connection methods.

[0053] In some embodiments, the shell 10 includes a frame 32, which encloses a accommodating space 22. The surface of the frame 32 facing the accommodating space 22 is in direct contact with the second surface 20. The frame 32 includes a first mounting portion 34, the first mounting portion 34 includes one of a slot 36 and a strip 38, and the second mounting portion includes the other of the slot 36 and the strip 38. The strip 38 is clamped in the slot 36 to limit the position of the heat conductor 12 in the accommodating space 22 in the first direction and the second direction.

[0054] In this way, the heat conducting member 12 of the housing 10 is fixed by the clamping strip 38 and the clamping groove 36 , which is easy to install and has high connection strength.

[0055] Specifically, the housing 10 includes a frame 32, and the frame 32 encloses the accommodating space 22. The frame 32 includes a first mounting portion 34, and the heat conductive member 12 includes a second mounting portion. The first mounting portion 34 includes one of a slot 36 and a strip 38, and the second mounting portion includes the other of the slot 36 and the strip 38. The strip 38 is clamped in the slot 36, and the position of the heat conductive member 12 in the accommodating space 22 is limited in the first direction and the second direction, so as to fix the heat conductive member 12 in the accommodating space 22.

[0056] In the illustrated embodiment, the heat conducting member 12 includes a clip 38, which is disposed on the surface of the second heat conducting plate 24 facing the accommodation space 22. The frame 32 includes a first mounting portion 34, and a clip slot 36 is provided on the first mounting portion 34. When the heat conducting member 12 and the inverter 14 are installed in the accommodation space 22, the clip 38 slides into the clip slot 36, and the position of the heat conducting member 12 in the accommodation space 22 can be limited along the first direction and the second direction, so that the heat conducting member 12 can be fixed in the accommodation space 22. Figure 3 As shown, the first direction is the left-right direction, and the second direction is the up-down direction.

[0057] In other embodiments, the heat conducting member 12 defines a slot 36 , and the first mounting portion 34 of the frame 32 includes a clip 38 . The slot 36 and the clip 38 cooperate with each other to fix the heat conducting member 12 in the accommodating space 22 .

[0058] In some embodiments, the housing 10 further includes a cover plate 46 , and the frame 32 is formed with two opposite openings 40 . The two cover plates 46 respectively close the two openings 40 to limit the position of the heat conducting member in the accommodating space 22 in the third direction.

[0059] In this way, the components inside the energy storage device 100 are installed in the accommodating space 22 through the opening 40 formed by the frame 32, and the opening 40 is closed with the cover plate 46, so that a relatively closed accommodating space 22 can be formed, which plays a role in fixing and protecting the components inside the energy storage device 100.

[0060] Specifically, the frame 32 is formed with two opposite openings 40, and the openings 40 are used to install the components inside the energy storage device 100 into the accommodating space 22. When installing the inverter 14 and the heat conductor 12, the inverter 14 is fixed on the heat conductor 12 and slides into the card slot 36 along with the clamping strip 38 of the heat conductor 12. After the internal components of the energy storage device 100 are installed, the two openings 40 are closed with the cover plate 46, so that the cover plate 46 can fix the heat conductor 12 in the third direction. At the same time, after the cover plate 46 closes the opening 40, the accommodating space 22 inside the energy storage device 100 is relatively closed, and the cover plate 46 and the frame 32 can protect the internal components.

[0061] Among them, Figure 3 As shown, the third direction is the front-to-back direction.

[0062] See also Figure 8 In some embodiments, the energy storage device 100 includes a seal 42 disposed between the cover plate 46 and the frame 32 .

[0063] In this way, the accommodating space 22 inside the energy storage device 100 can be relatively closed, so that the housing 10 composed of the cover plate 46 and the frame body 32 has dustproof and waterproof protection functions.

[0064] Specifically, the energy storage device 100 includes a seal 42, which is disposed between the cover plate 46 and the frame 32. When the cover plate 46 is fixed to the frame 32 to close the opening 40 of the frame 32, the seal 42 can keep the accommodating space 22 inside the energy storage device 100 relatively closed, and to a certain extent can prevent dust or liquid from entering the energy storage device 100 and causing damage to the internal components of the energy storage power supply.

[0065] In one embodiment, the sealing member 42 comprises a silicone sealing ring, which has a good waterproof sealing effect.

[0066] See also Figure 6 and Figure 8In some embodiments, the frame 32 defines a third mounting hole 44, the cover plate 46 defines a fourth mounting hole 45, and the energy storage device 100 includes a second fastener (not shown), which passes through the third mounting hole 44 and the fourth mounting hole 45 to fix the cover plate 46 and the frame 32.

[0067] In this way, the cover plate 46 and the frame body 32 are fixedly connected by the second fastener, the connection strength is high, and the installation is simple and convenient.

[0068] Specifically, the frame 32 defines a third mounting hole 44, and the cover plate 46 defines a fourth mounting hole 45. The energy storage device 100 includes a second fastener. When the frame 32 and the cover plate 46 are fixedly connected, the second fastener passes through the third mounting hole 44 and the fourth mounting hole 45 to fix the cover plate 46 and the frame 32.

[0069] In some embodiments, the first mounting portion 34 has a hollow portion 48 .

[0070] In this way, the weight of the frame 32 can be reduced while ensuring that the first mounting portion 34 has a certain structural strength.

[0071] Specifically, Figure 5 and Figure 7 As shown, the first mounting portion 34 is fixedly connected to the heat conducting member 12. The first mounting portion 34 has a hollow portion 48, which can ensure the structural strength of the first mounting portion 34, while reducing the amount of material used to manufacture the frame 32 and reducing the weight of the frame 32.

[0072] In some embodiments, the heat conducting member 12 is an aluminum alloy heat conducting member 12 .

[0073] In this way, the heat conducting element 12 has a good heat conducting effect.

[0074] Specifically, aluminum alloy has high strength and good thermal conductivity, and has good heat transfer effect when in contact with the inverter 14. At the same time, metal materials are easy to process. The heat conducting member 12 is made of aluminum alloy.

[0075] In other embodiments, the material of the heat conducting member 12 can also be other metals or materials with good thermal conductivity. Among them, a suitable material can be selected as the heat conducting member according to the thermal conductivity of the material.

[0076] In some embodiments, the housing 10 is an aluminum alloy housing 10 .

[0077] In this way, the housing 10 can have better heat conduction and heat dissipation effects, and at the same time can protect the functional modules inside it.

[0078] Specifically, the heat conductor 12 is in direct contact with one surface of the housing 10. The housing 10 is made of aluminum alloy, which can better transfer heat and quickly dissipate heat and cool down. As a metal housing 10, the aluminum alloy housing 10 is relatively light in weight and has good hardness, which can protect the functional modules inside it.

[0079] In other embodiments, the material of the housing 10 may also be other metals or other materials besides metal.

[0080] In one embodiment, the frame 32 of the shell 10 is made of metal, and the cover 46 is made of plastic. The frame 32 is in contact with the heat conductive element 12 to achieve better heat conduction and heat dissipation functions. In combination with the plastic frame 32, the energy storage device 100 can be lightweight as a whole, making it easy to transport and carry.

[0081] In some embodiments, the thermal conductor 12 is made by an integral molding process.

[0082] In this way, the processing method of the heat conducting member 12 is simplified and the processing efficiency is improved.

[0083] Specifically, the use of an integrated molding process can make the processing size control more precise, reduce the processing error, and greatly improve the processing efficiency. At the same time, it can reduce the manufacturing process of parts and the process of welding, thereby shortening the manufacturing cycle and reducing the manufacturing cost.

[0084] In some embodiments, the energy storage device 100 further includes a battery module 50. The battery module 50 is fixedly connected to the cover plate 46 and accommodated in the accommodation groove.

[0085] In certain embodiments, the energy storage device 100 further includes a decorative member 52 , which is mounted on the cover plate 46 and can protect the cover plate 46 .

[0086] In summary, the assembly process of the energy storage device 100 is as follows: first, place the inverter 14 on the first heat-conducting plate 16 of the heat-conducting member 12, and place the MOS tubes at both ends close to the second heat-conducting plate 24 of the heat-conducting member 12 to form a heat-dissipating inverter 14. Then, align the clip 38 on the heat-conducting member 12 of the heat-dissipating inverter 14 with the clip slot 36 of the frame 32, and gently push the heat-dissipating inverter 14 into the accommodating space 22. Then, install other functional modules in the energy storage power supply, such as display screens, terminals and other devices to the frame 32, and assemble the battery module 50 on the cover plate 46. Finally, place a sealing ring between the cover plate 46 and the frame 32, and fix the cover plate 46 to the frame 32, and the installation is completed.

[0087] The energy storage power supply according to the above-mentioned embodiment has the following effects: 1. Heat is dissipated through the heat conductor 12 and the shell 10, and there is no need to install a cooling fan, thereby achieving zero-noise heat dissipation; 2. The whole machine has fewer parts, fewer installation steps, and simple installation, which can effectively reduce the installation process and manpower; 3. The protective performance is high. The shell 10 is made of metal material with high strength, which has a good protective effect on the devices inside it, and is sealed with a sealing ring to achieve a waterproof and dustproof effect.
