[0048] Energy storage power supplies are often used outdoors and require high levels of water and dust resistance. Therefore, their enclosures are typically highly sealed to ensure this performance. However, this tight enclosure is detrimental to heat dissipation. Specifically, energy storage power supplies include an inverter, which is housed within the enclosure and contains power components. The substantial heat generated by these components during operation cannot be efficiently dissipated through the sealed enclosure, impacting the performance and lifespan of the energy storage power supply.

[0049] See also Figure 1The energy storage power supply 100 of the embodiment of the present application includes a housing 10, a battery module 50, an inverter 30 and a heat conduction member 40. The housing 10 is formed with a accommodating cavity 11 and a heat dissipation channel 20 isolated from the accommodating cavity 11, and the heat dissipation channel 20 is connected to the outside; the battery module 50 is arranged in the accommodating cavity 11; the inverter is electrically connected to the battery module 50, and the inverter 30 is arranged in the accommodating cavity 11; the heat conduction member 40 includes a heated end 41 and a cooled end 42. The heat conduction member 40 is arranged in the housing 10 so that the heated end 41 is thermally coupled with the inverter 30 and the cooled end 42 is located in the cooled end 20. The heat conduction member 40 is configured to conduct the heat generated by the inverter 30 into the cooled end 20 and then dissipate it to the outside.

[0050] The energy storage power supply 100 provided in the present application is provided with a heat dissipation channel 20 isolated from the interior of the housing 10. A heat conducting member 40 having multiple cooling ends 42 extending into the heat dissipation channel 20 is used to transfer heat from the interior of the energy storage power supply 100 along the heat conducting member 40 to the heat dissipation channel 20 and dissipate it to the outside. This improves the heat dissipation capability of the energy storage power supply 100 while not affecting the protection level of the energy storage power supply 100. This effectively cools the interior of the energy storage power supply 100, avoids excessive internal temperatures that could affect the normal operation of internal components, reduces safety hazards, and ensures the performance and service life of the energy storage power supply 100.

[0051] Specifically, in the embodiment of the present application, the housing 10 includes a main housing and a heat dissipation channel 20. The heat dissipation channel 20 is in the shape of a rectangular tube. In some embodiments, the heat dissipation channel 20 can be detachably connected to the main housing by fasteners.

[0052] Inverter 30 refers to a semiconductor device capable of handling high voltage and high current. It plays a crucial role in electronic devices, converting and controlling electrical energy and typically generating significant heat during operation. In the present embodiment, inverter 30 includes, but is not limited to, components such as the inductor, transformer, and surface-mount MOSFET.

[0053] The heat conducting member 40 is a component used to transfer heat generated inside the energy storage power supply 100 to the heat dissipation channel 20. In the embodiment of the present application, the heat conducting member 40 is a high-purity copper heat pipe with a thermal conductivity of 20,000 W / mK or more. Furthermore, there are multiple heat conducting members 40, and the multiple heat conducting members 40 are evenly spaced apart in the housing 10. In the embodiment of the present application, the multiple heat conducting members 40 are straight heat pipes of the same length, and the multiple heat pipes are evenly spaced apart in the housing 10, with the spacing between two adjacent heat pipes being the same.

[0054] In other embodiments, the heat conducting member 40 may also be configured in other shapes. Specifically, the heat receiving end 41 may be arranged along the position of the inverter 30 .

[0055] See also Figures 2 to 4 In some embodiments, the shell 10 includes a first shell 12 and a second shell 13, the first shell 12 is provided with a first air outlet 122, the second shell 13 is provided with a second air outlet 132, one end of the heat dissipation channel 20 cooperates and docks with the front air cavity 121, and the other end of the heat dissipation channel 20 cooperates and docks with the rear air cavity 131.

[0056] In this way, the first air outlet 122 and the second air outlet 132 are provided to cooperate with the heat dissipation channel 20 , which is beneficial to the isolation and sealing between the housing 10 and the heat dissipation channel 20 .

[0057] Specifically, in the embodiment of the present application, a first air outlet 122 is provided on the first shell 12, and a rib structure is provided on the inner side of the first shell 12 around the first air outlet 122, and the rib structure forms a rectangular frame-shaped front air cavity 121. Similarly, a second air outlet 132 is provided on the second shell 13, and a rib structure is provided on the inner side of the second shell 13 around the second air outlet 132, and the rib structure forms a rectangular frame-shaped rear air cavity 131.

[0058] Furthermore, the opening shape and size of the front air cavity 121 are exactly the same as the shape and size of the opening at one end of the heat dissipation channel 20, and the opening shape and size of the rear air cavity 131 are exactly the same as the shape and size of the opening at the other end of the heat dissipation channel 20. In the embodiment of the present application, the rectangular frame formed by the front air cavity 121 and the rear air cavity 131 is equal in size and has the same shape as the rectangular frame formed by the cross-section of the heat dissipation channel 20.

[0059] In the embodiment of the present application, the first air outlet 122 is formed by a plurality of evenly arranged first openings. This helps to make the air entering the heat dissipation channel 20 more uniform and helps to reduce the noise generated by the air flow. Similarly, the second air outlet 132 is formed by a plurality of evenly arranged second openings.

[0060] See also Figure 2 In some embodiments, the energy storage power supply 100 further includes a fan 23 , which is disposed in the heat dissipation channel 20 .

[0061] In this way, the fan 23 can increase the speed and flow rate of air circulation in the heat dissipation channel 20 , which is beneficial to improving the heat dissipation efficiency of the energy storage power supply 100 .

[0062] Specifically, in the embodiment of the present application, the fan 23 is rectangular, and the shape of the fan 23 is basically the same as the rear air cavity 131, and the size is slightly smaller than the rear air cavity 131. The fan 23 is clamped in the rear air cavity 131 so that the outside air enters from the second air outlet 132 and blows into the heat dissipation channel 20 through the fan 23.

[0063] In some embodiments, the fan 23 may also be configured to be mounted in the rear air cavity 131 so as to blow the hot air in the heat dissipation channel 20 out from the second air outlet 132 through the fan 23 .

[0064] In some embodiments, the fan 23 can also be installed in the front air cavity 121 so that the outside air enters from the first air outlet 122 and is blown into the heat dissipation channel 20 through the fan 23, or the hot air in the heat dissipation channel 20 is blown out from the first air outlet 122 through the fan 23.

[0065] See also Figure 5 In some embodiments, the inverter 30 includes a temperature sensor 31 and a control component 32. The temperature sensor 31 is electrically connected to the control component 32. The fan 23 is electrically connected to the control component 32. The temperature sensor 31 controls the speed of the fan 23 through the control component 32.

[0066] In this way, the temperature sensor 31 and the control component 32 can adjust the fan speed according to the real-time temperature inside the energy storage power supply 100 to achieve precise temperature control.

[0067] Specifically, in the embodiment of the present application, the temperature sensor 31 selects a high-precision NTC or a high-precision temperature sensor, the control component 32 is an intelligent controller, and the temperature sensor 31 monitors the internal temperature changes in real time and transmits the data to the intelligent controller.

[0068] Furthermore, control component 32 incorporates advanced control algorithms (such as fuzzy control and neural network control) that adjust fan speed and cooling strategies in real time based on data from temperature sensor 31, achieving precise temperature control. Control component 32 also features fault diagnosis and self-protection capabilities, ensuring the device automatically shuts down and issues an alarm in the event of an abnormality.

[0069] It is easy to understand that the position between multiple inverters 30 is very likely to cause local excessive temperature due to the heat emitted by the surrounding multiple inverters 30, thereby causing components to burn out. Therefore, the temperature sensor 31 should be set at the position between multiple inverters 30 to more accurately control the temperature here to avoid local excessive temperature.

[0070] In some embodiments, the energy storage power supply 100 further includes a plurality of seals 60 , which are respectively disposed between the heat dissipation channel 20 and the first housing 12 and between the heat dissipation channel 20 and the second housing 13 .

[0071] In this way, the housing 10 and the heat dissipation channel 20 can be isolated, thereby achieving sealing inside the housing 10 , which is beneficial for ensuring the protection level of the energy storage power supply 100 .

[0072] Specifically, in the embodiment of the present application, all interfaces and gaps are sealed with high-quality seals 60 or sealing materials to ensure that the waterproof and dustproof level reaches IP67 or above. The sealing structure is rigorously tested to ensure that it can maintain stable performance in harsh environments.

[0073] Furthermore, seals 60 are installed between the heat dissipation channel 20 and the front air cavity 121, and between the heat dissipation channel 20 and the rear air cavity 131. Seals 60 are gaskets. It is important to note that when installing these gaskets, the sealing surfaces must be clean, dust-free, and free of defects such as scratches or spots, as this will directly affect the sealing performance. Furthermore, the preload force should be controlled within the specified range to avoid excessive compression that could cause the gasket to lose its resilience, thereby affecting the sealing effect.

[0074] Optionally, the material of the sealing member 60 may be silicone rubber, plastic, cowhide, asbestos, polyurethane, etc. The specific material of the sealing member 60 may be adjusted according to actual needs and will not be elaborated here.

[0075] In some embodiments, sealant may be applied between the heat dissipation channel 20 and the front air cavity 121 and between the heat dissipation channel 20 and the rear air cavity 131 for bonding. It should be noted that, with such a setting, when the heat dissipation channel 20 and the shell 10 are disassembled and reconnected, the original sealant has become ineffective and the surface needs to be cleaned and reapplied with sealant.

[0076] See also Figure 2 In some embodiments, the energy storage power supply 100 further includes a waterproof and dustproof component 70 , which is attached to the inner side of the first air outlet 122 and the inner side of the second air outlet 132 .

[0077] In this way, a waterproof and dustproof component 70 is provided at the first air outlet 122 and the second air outlet 132, which is beneficial to preventing the entry of dust and water, and can prevent moisture and dust from entering the interior of the energy storage power supply 100, and can also prevent moisture from contacting the heat conduction element 40 and causing the heat conduction element 40 to rust.

[0078] Specifically, the waterproof and dustproof component 70 includes a waterproof breathable membrane and a dustproof net. Both the waterproof breathable membrane and the dustproof net have high air permeability and good filtering performance, which can ensure air circulation and effectively prevent the intrusion of moisture and dust.

[0079] Furthermore, the waterproof and breathable membrane and dust-proof net arranged in the front air cavity 121 are the same size as the inner surface of the front air cavity 121, and the waterproof and breathable membrane and dust-proof net are arranged in the front air cavity 121 and completely cover the first air outlet 122. Similarly, the waterproof and breathable membrane and dust-proof net arranged in the rear air cavity 131 are the same size as the inner surface of the rear air cavity 131, and the waterproof and breathable membrane and dust-proof net are arranged in the rear air cavity 131 and completely cover the second air outlet 132.

[0080] See also Figure 5 In some embodiments, the energy storage power supply 100 further includes a heat dissipation substrate 80, which is thermally coupled to the heat dissipation channel 20 through a heat conduction member 40. The inverter 30 is disposed on the heat dissipation substrate 80. A receiving groove 81 is further provided on the surface of the heat dissipation substrate 80 where the inverter 30 is disposed. The receiving groove 81 is used to mount the heated end 41.

[0081] In this way, the heat conducting member 40 can be brought into more direct contact with the inverter 30 , thereby improving heat dissipation efficiency.

[0082] Specifically, in the embodiment of the present application, the heat dissipation substrate 80 is in the shape of a rectangular plate, and the heat dissipation substrate 80 and the heat dissipation channel 20 are an integral structure that is integrally processed and formed.

[0083] Furthermore, the heat dissipation substrate 80 is made of a lightweight and high-strength aluminum alloy material. The aluminum alloy material has good thermal conductivity, which is beneficial to improving the heat dissipation efficiency. In addition, the aluminum alloy is light in weight compared to other metals and alloys, which is beneficial to the lightweighting of the energy storage power supply 100.

[0084] In some embodiments, a side of the heat dissipation substrate 80 away from the heat dissipation channel 20 extends in a direction perpendicular to the heat dissipation substrate 80 to form an auxiliary heat dissipation plate 82 .

[0085] In this way, the area of ​​the heat dissipation substrate 80 can be increased, so that more heat generated by the inverter 30 is transferred to the heat dissipation substrate 80 and dissipated through the heat conduction member 40 , thereby improving the heat dissipation capability.

[0086] Specifically, in the embodiment of the present application, the auxiliary heat sink 82 extends upward in a direction perpendicular to the heat sink base 80. The auxiliary heat sink 82, the heat sink base 80, and the heat sink channel 20 are integrally formed into an integrated structure.

[0087] Furthermore, the height of the auxiliary heat sink 82 should be slightly lower than the height of the power components to prevent the auxiliary heat sink 82 from being too high and occupying too much space.

[0088] See also Figure 6 In some embodiments, a plurality of heat dissipation fins 21 are provided inside the heat dissipation channel 20 , and the cooling end 42 passes through the plurality of heat dissipation fins 21 .

[0089] In this way, the plurality of heat dissipation fins 21 can increase the heat dissipation area of ​​the heat conduction element 40 , thereby assisting the heat conduction element 40 in heat dissipation and improving the heat dissipation efficiency of the heat conduction element 40 .

[0090] Specifically, in the embodiment of the present application, the heat dissipation fins 21 are arranged along the length direction of the heat dissipation channel 20 , and the upper and lower sides of the heat dissipation fins 21 are respectively connected to the upper and lower top surfaces of the heat dissipation channel 20 .

[0091] Furthermore, the plurality of heat dissipation fins 21 are all in a long rectangular shape, the plurality of heat dissipation fins 21 are arranged parallel to each other, and the intervals between any two of the plurality of heat dissipation fins 21 are the same.

[0092] In the embodiment of the present application, the cooling end 42 passes through all the heat dissipation fins 21 . In other embodiments, the cooling end 42 may only pass through part of the heat dissipation fins 21 .

[0093] In some embodiments, a thermally conductive silicone 22 is disposed between the cooling end 42 and the plurality of heat dissipation fins 21 .

[0094] Thus, the thermal conductive silicone 22 is disposed between the heat conducting member 40 and the heat dissipating fins 21 , which can reduce the thermal resistance between the heat conducting member 40 and the heat dissipating fins 21 and improve the heat transfer efficiency.

[0095] Specifically, in the embodiment of the present application, it is necessary to fill the gaps between the cooling end 42 and the plurality of heat dissipation fins 21 with thermally conductive silicone 22. This can reduce the thermal resistance between the heat conduction member 40 and the heat dissipation fins 21, and can also form a seal between the heat conduction member 40 and the heat dissipation channel 20 to prevent the heat dissipation channel 20 from being connected to the accommodating cavity 11.

[0096] In other embodiments, a heat-conducting silicone rubber 22 sleeve may be provided on the outer surface of the cooling end 42 , and then the cooling end 42 sleeved with the heat-conducting silicone rubber 22 sleeve is embedded in the heat dissipation fins 21 .

[0097] In some embodiments, the heat dissipation channel 20 and the heat dissipation fins 21 are made of aluminum alloy.

[0098] Thus, aluminum alloy has good thermal conductivity, which is beneficial to improving heat dissipation efficiency, and aluminum alloy is lighter than other metals and alloys, which is beneficial to lightweighting of the energy storage power supply 100.

[0099] Specifically, in the embodiment of the present application, the auxiliary heat sink 82, the heat sink substrate 80, the heat sink channel 20 and the heat sink fins 21 are an integrated hot-extruded structure of aluminum alloy. During processing, multiple connected structures are usually pressurized at one time and then divided into multiple parts by cutting. This helps reduce costs and facilitates controlling the length of the heat sink channel 20.

[0100] In some embodiments, the auxiliary heat sink 82, the heat sink substrate 80, the heat sink channel 20 and the heat sink fins 21 may also be separate structures that are processed and formed separately, and are assembled and fixed by fasteners.

[0101] In some embodiments, the auxiliary heat sink 82, heat sink substrate 80, heat sink channel 20 and heat sink fins 21 can also be made of other metals or alloys such as iron, copper, stainless steel, etc. The specific material can be selected according to actual needs and will not be elaborated here.

[0102] In some embodiments, the heat conducting element 40 is hollow and filled with a refrigerant.

[0103] In this way, the heat conducting member 40 is filled with a refrigerant and the refrigerant is used as a carrier for heat transfer, which is beneficial to improving the heat dissipation efficiency.

[0104] Specifically, in the embodiment of the present application, the heat conduction member 40 is in the shape of a hollow tube, and refrigerant is added inside it. Furthermore, the filling rate of the refrigerant is 50% to 70%. In this way, a certain space reserved in the heat conduction member 40 is conducive to ensuring smooth flow of the refrigerant and avoiding problems such as liquid hammer. Filling an appropriate amount of refrigerant can optimize the operating efficiency of the system and ensure that there is enough refrigerant to evaporate, thereby absorbing more heat and improving the cooling efficiency.

[0105] In some embodiments, the heat conducting element 40 may be filled with anhydrous ethylene glycol or other coolant instead of the refrigerant.

[0106] In some embodiments, the plurality of heat conducting elements 40 may be connected to each other, and the refrigerant may flow between the plurality of heat conducting elements 40 through a power assembly.

[0107] See also Figure 7 In some embodiments, the heating end 41 is flat and the cooling end 42 is cylindrical.

[0108] In this way, the flat heat-receiving end 41 is conducive to better absorbing the heat inside the energy storage power supply 100 , and the cylindrical cooling end 42 is conducive to maximizing the heat dissipation area, so that the heat can be better dissipated into the heat dissipation channel 20 .

[0109] Specifically, the flat heating end 41 can spread the refrigerant flatly on the heating end 41, so that the refrigerant filled inside the heating end 41 can more fully absorb the heat emitted by the power components. The cylindrical cooling end 42 is conducive to maximizing the heat dissipation area and is conducive to gathering and returning the cooled refrigerant to the heating end 41. In the embodiment of the present application, the width of the heating end 41 is the same as the diameter of the cooling end 42 to facilitate the processing of the heat conduction component 40.

[0110] In some embodiments, the width of the heated end 41 may also be greater than the diameter of the cooled end 42 .

[0111] See also Figure 5 In some embodiments, the energy storage power supply 100 further includes a heat conductive material 90 , which is disposed between the inverter 30 and the heated end 41 .

[0112] In this way, the heat conductive material 90 is provided between the inverter 30 and the heat conductive member 40 , which can reduce the thermal resistance between the inverter 30 and the heat conductive member 40 and improve the heat transfer efficiency.

[0113] Specifically, in the embodiment of the present application, since the inverter 30 is thermally coupled to the heat receiving end 41 , in order to ensure the transfer efficiency, a heat conducting material 90 needs to be added between the inverter 30 and the heat receiving end 41 .

[0114] Furthermore, optionally, the thermal conductive material 90 uses a high-performance thermal interface material (TIM), such as a phase change material or a high thermal conductivity silicone pad 22, to further reduce thermal resistance and improve heat transfer efficiency.

[0115] In the embodiment of the present application, the heat conductive material 90 is disposed in a block shape between the inverter 30 and the heated end 41 . In other embodiments, the heat conductive material 90 may also be applied in a gel-like shape between the inverter 30 and the heated end 41 .
