Detailed Implementation

[0059] The core of this application lies in disclosing an energy storage enclosure. The energy storage enclosure disclosed in this application includes an enclosure body and a cooling medium supply device. The enclosure body includes a first side plate, on which a first channel for the cooling medium to pass is provided. The first channel directly or indirectly exchanges heat with the external environment. The cooling medium supply device is connected to the first channel and supplies cooling medium into the first channel. The cooling medium can be a coolant, a phase change cooling medium, or a cooling airflow. The cooling medium supply device 300 includes, but is not limited to, a liquid chiller, a fan, etc. The energy storage enclosure disclosed in this application can reduce the space occupied by the heat dissipation system inside the energy storage enclosure.

[0060] Another key aspect of this application is the disclosure of an energy storage device that includes the aforementioned energy storage box.

[0061] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0062] Exemplary, in some embodiments, combined with Figure 1 and Figure 2The first side plate of the housing body 100 is provided with a first channel 201 for the passage of cooling medium. During the flow of cooling medium through the first channel 201, the cooling medium in the first channel 201 can exchange heat with the external environment. The housing body 100 includes multiple enclosure plates, at least one of which serves as the aforementioned first side plate. The enclosure plates together enclose the housing body 100 to form a housing body 100 with a certain internal cavity. The cooling medium supply device 300 can be installed on one of the enclosure plates of the housing body 100 and located outside the housing body 100, or it can be installed inside the housing body 100, or the cooling medium supply device 300 can be installed independently of the housing body 100.

[0063] Combination Figure 2 In the actual heat dissipation process, the cooling medium supplied by the cooling medium supply device 300 enters the interior of the housing body 100 through the internal heat dissipation pipe (not shown in the figure) and carries away the heat of the heat-generating components inside the housing body 100. The heat-generating components inside the housing body 100 include, but are not limited to, power conversion devices, batteries, etc. Along the flow direction of the cooling medium, the first channel 201 can be specifically connected in series between the outlet of the cooling medium supply device 300 and the inlet of the internal heat dissipation pipe, or between the outlet of the internal heat dissipation pipe and the return port of the cooling medium supply device 300. When the first channel 201 is connected in series between the outlet of the cooling medium supply device 300 and the inlet of the internal heat dissipation pipe, the cooling medium supplied by the cooling medium supply device 300 flows sequentially through the first channel 201, the internal heat dissipation pipe, and the heat exchanger 410, and finally flows back to the cooling medium supply device 300. When the first channel 201 is connected in series between the outlet of the internal heat dissipation pipe and the return port of the cooling medium supply device 300, the cooling medium supplied by the cooling medium supply device 300 flows sequentially through the internal heat dissipation pipe, the first channel 201, and the heat exchanger 410, or sequentially through the internal heat dissipation pipe, the heat exchanger 410, and the first channel 201, and finally flows back to the cooling medium supply device 300. The cooling medium carries away the heat from the heat-generating components inside the housing 100 through the internal heat dissipation pipes. It can then naturally dissipate heat to the external environment at the heat exchanger 410 or be forced to cool by a fan 400. It also exchanges heat with the external environment at the first channel 201 and cools naturally.

[0064] The types of heat exchangers 410 mentioned above include, but are not limited to, air-cooled heat exchangers, finned heat exchangers, and microchannel heat exchange devices. The internal heat dissipation pipes include pipes connecting the cooling medium supply device 300 to the inside of the housing body 100, pipes on the heat-generating components inside the housing body 100, etc. For example, they can specifically be the main flow channel pipes and branch flow channel pipes of the battery module, pipes for the liquid cooling plate that dissipates heat from the battery module, etc.

[0065] Compared to existing technologies, the energy storage box disclosed in this application, based on the original heat dissipation system, increases the heat exchange area between the heat dissipation system and the external environment by adding a first channel 201 as an auxiliary heat exchange structure on the first side plate, thereby improving heat dissipation efficiency. This can reduce the power required by the original heat dissipation system, thereby reducing the number of heat exchangers 410 and fans 400 and / or reducing the size and power of heat exchangers 410 and fans 400, reducing costs, and reducing their occupation of the internal space of the energy storage box. At the same time, since the first channel 201 can be arranged by setting it inside the first side plate or by attaching it to the outer wall of the first side plate, it occupies less space and can ensure the space utilization rate of the energy storage box.

[0066] For example, the energy storage container disclosed in this application can specifically be an energy storage container. In some embodiments, the energy storage container is provided with a general compartment 101 and a battery compartment 102. The general compartment 101 is used to install and store the control unit, inverter, converter, monitoring system, or other electrical equipment of the energy storage system. These devices are responsible for managing the operation of the entire energy storage system. The battery compartment 102 is used to store battery modules or battery packs. Combined with... Figure 1 The energy storage container has a heat exchanger 410 and a fan 400 mounted on its top plate. At least two of the four circumferential side plates of the energy storage container need to serve as doors for the integrated compartment 101 and the battery compartment 102, respectively. Therefore, all circumferential side plates except those with doors can serve as the first side plates for the first channel 201. Additionally, a second channel for the cooling medium can be provided on the bottom plate of the energy storage container to further improve heat exchange efficiency. See below for the specific structure. (Combined with...) Figure 6 It shows a structure that uses the large side panel of an energy storage container as the first side panel and arranges the first channel 201.

[0067] It should be noted that in the accompanying drawings of this application embodiment, the arrow labeled Z represents the first direction Z, the arrow labeled X represents the second direction X, and the arrow labeled Y represents the third direction Y. The first direction Z, the second direction X, and the third direction Y are all perpendicular to each other. The first direction Z, the second direction X, and the third direction Y are introduced to more clearly illustrate the structure and relative positional relationship of each component in the energy storage box. In practical applications, the first direction Z, the second direction X, and the third direction Y may change depending on the placement of the energy storage box. For example, the following description will use the first direction Z as the height direction of the energy storage box, the second direction X as the length direction of the energy storage box, and the third direction Y as the width direction of the energy storage box.

[0068] Specifically, the first liquid inlet 202 and the first liquid outlet 203 of the first channel 201 can be located at the same or different side positions of the first side plate, so as to facilitate the connection of the first channel 201 with the cooling medium supply device 300 located on one side of the first side plate, and with the liquid inlet or liquid outlet of the heat exchanger 410, thereby shortening the length of the connecting pipe, reducing the complexity of the structure, and facilitating management.

[0069] For example, in combination Figure 1 and Figure 2 Taking the first side plate as a circumferential side plate, that is, the surface of the first side plate is parallel to the Z direction, the first inlet 202 and the first outlet 203 of the first channel 201 can be located at any side position of the first side plate along the first direction Z or the second direction X. Specifically, when the first inlet 202 is located at the side position of the first side plate along the second direction X, the first outlet 203 can be located at the side position of the first side plate along the second direction X, or located at the side position of the first side plate along the second direction X. The first liquid inlet 202 is located at the side position of the second side opposite to the side position of the first side plate along the first direction Z; when the first liquid inlet 202 is located at the side position of the first side plate along the first direction Z, the first liquid outlet 203 can be located at the side position of the first side plate along the first direction Z, or at the side position of the second side opposite to the side position of the first side plate along the first direction Z, or at the side position of the first side plate along the second direction X.

[0070] Taking the first side plate as the base plate, i.e., the surface of the first side plate is perpendicular to the Z direction, the first inlet 202 and the first outlet 203 of the first channel 201 can be located at any side position of the first side plate along the second direction X or the third direction Y. Specifically, when the first inlet 202 is located at the side position of the first side plate along the second direction X, the first outlet 203 can be located at the side position of the first side plate along the second direction X, or located at the side position of the first side plate along the second direction X. The first liquid inlet 202 can be located at the side position of the first side plate opposite to the side position of the first side plate along the third direction Y, or at a side position of the first side plate opposite to the side position of the first side plate along the third direction Y, or at a side position of the first side plate along the third direction Y.

[0071] When a heat dissipation channel for cooling medium to pass through is also provided on a certain enclosure plate of the housing body 100 other than the first side plate, such as the second channel provided on the second side plate below, the first channel 201 and the second channel can be connected by a pipe, and the first liquid inlet 202 and / or the first liquid outlet 203 of the first channel 201 can be provided at a side position close to the second side plate to facilitate series connection with the second channel.

[0072] Specifically, the first liquid inlet 202 and the first liquid outlet 203 of the first channel 201 can be located at the middle or edge of one side of the first side plate. The location can be adjusted adaptively according to the positions of the inlet and outlet of the heat dissipation channels through which the cooling medium passes on the cooling medium supply device 300, the heat exchanger 410, and other enclosure plates of the housing body 100. The first channel 201 can be connected to the cooling medium supply device 300, the heat exchanger 410, and other heat dissipation channels via pipes.

[0073] In some embodiments, the first inlet 202 and the first outlet 203 of the first channel 201 are respectively located at the middle position of the sides of opposite sides of the first side plate, and the first channel 201 is symmetrically arranged with respect to the line connecting the first inlet 202 and the first outlet 203. For example, when the first side plate is a circumferential side plate, the first inlet 202 and the first outlet 203 of the first channel 201 are both located at the middle position of the sides of the first side plate along the second direction X, and the first channel 201 is symmetrically arranged with respect to the line connecting the first inlet 202 and the first outlet 203; or, the first inlet 202 and the first outlet 203 of the first channel 201 are both located at the middle position of the sides of the first side plate along the first direction Z, and the first channel 201 is symmetrically arranged with respect to the line connecting the first inlet 202 and the first outlet 203. This symmetrical arrangement can improve the distribution of cooling medium and the uniformity of heat dissipation in the first channel 201, thereby improving the heat dissipation effect. Figure 6 and Figure 7 It illustrates a technical solution in which a first liquid inlet 202 and a first liquid outlet 203 are respectively located at the middle positions on both sides of a first side plate along the first direction Z, and the first channel 201 is symmetrically arranged with respect to the line connecting the first liquid inlet 202 and the first liquid outlet 203. In air-cooling mode, the coolant supplied by the cooling medium supply device 300 first flows along... Figure 7 The coolant on the battery side flows through internal heat dissipation pipes to exchange heat with the heat-generating components inside the casing 100, and then along... Figure 7 The coolant in the first channel of the middle channel exchanges heat with the external environment for the first time, and then... Figure 7 The coolant on the middle heat exchanger side flows through heat exchanger 410 to exchange heat with the external environment for a second time, and finally flows along... Figure 7The coolant on the liquid-cooled main unit side flows back to the cooling medium supply device 300, waiting to be supplied to the internal heat dissipation pipes again to complete one heat dissipation cycle.

[0074] A further optimized design involves positioning the first inlet 202 of the first channel 201 below the first outlet 203 along the first direction Z. This improves the heat dissipation performance of the first channel 201 and enhances the uniformity of the cooling medium distribution within it. It also reduces turbulence and vibration of the cooling medium, thereby lowering noise levels and facilitating maintenance. Alternatively, the housing body 100 may include the aforementioned second side plate, connected to the first side plate. Positioned below the first side plate along the first direction Z, the first outlet 203 of the first channel 201 is located on the second side plate. This achieves the same technical effect as positioning the first inlet 202 below the first outlet 203, and will not be elaborated further here.

[0075] In some embodiments disclosed in this application, combined with Figure 6 and Figure 7 The first inlet 202 and the first outlet 203 of the first channel 201 are respectively located on both sides of the first side plate along the first direction Z. The first channel 201 includes a first main inlet channel 207, a first main outlet channel 209, and multiple first parallel branch channels 208. Each first parallel branch channel 208 extends along the first direction Z and is connected in parallel between the first main inlet channel 207 and the first main outlet channel 209. Specifically, the first main inlet channel 207 and the first main outlet channel 209 can be arranged in parallel and perpendicular to the first parallel branch channels 208, that is, parallel to the second direction X, to adapt to the rectangular shape of the first side plate. The structure is simple and convenient for layout. The first main inlet channel 207, the first main outlet channel 209, and each first parallel branch channel 208 can be an integral structure or a separate structure.

[0076] In other embodiments disclosed in this application, combined with Figure 9 The first inlet 202 and the first outlet 203 of the first channel 201 are respectively located on both sides of the first side plate along the second direction X. The first channel 201 includes a second main inlet channel 204, a second main outlet channel 206, and multiple second parallel branch channels 205. Each second parallel branch channel 205 extends along the second direction X and is connected in parallel between the second main inlet channel 204 and the second main outlet channel 206. Specifically, the second main inlet channel 204 and the second main outlet channel 206 can be arranged in parallel and perpendicular to the second parallel branch channels 205, that is, parallel to the first direction Z, to adapt to the rectangular shape of the first side plate. The structure is simple and convenient for layout. The second main inlet channel 204, the second main outlet channel 206, and each second parallel branch channel 205 can be an integral structure or a separate structure.

[0077] The first channel 201 can be directly disposed on the first side plate. In some embodiments, a first flow pipe 200 is disposed inside the first side plate and / or on the outer wall surface of the first side plate, forming the first channel 201. The first flow pipe 200 and the first side plate can be an integral structure or a separate structure. The first flow pipe 200 can be embedded inside the first side plate or disposed in close contact with the outer wall surface of the first side plate. The outer wall surface of the first side plate can be the outer wall surface facing the inner cavity of the housing body 100 or the outer wall surface facing away from the inner cavity of the housing body 100. When the aforementioned first flow pipe 200 is disposed on both the inner and outer wall surfaces of the first side plate, the heat exchange area can be effectively increased and the heat exchange efficiency can be improved.

[0078] In some embodiments, the first flow conduit 200 includes at least one heat dissipation pipe, and multiple heat dissipation pipes are connected end to end in sequence, forming a first channel 201 for unidirectional flow from the first liquid inlet 202 to the first liquid outlet 203. For example, Figure 10 and Figure 11 The diagram shows a first flow channel 200 that is a wire tube flow channel, and the wire tube flow channel is arranged in a serpentine pattern on the first side plate. Its structure is simple, not easy to leak air or liquid, and has low management cost.

[0079] In other embodiments, combined with Figure 12 and Figure 13 The first side plate adopts a thin plate structure and has a liquid storage cavity inside. The liquid storage cavity forms the first channel 201 mentioned above. Using the liquid storage cavity as the first channel 201 can effectively increase the heat dissipation area, thereby enhancing the heat dissipation effect.

[0080] The aforementioned heat dissipation pipes and liquid storage chambers can also be configured together. That is, a liquid storage chamber can be simultaneously installed inside the first side plate, and heat dissipation pipes can be installed on the outer wall of the first side plate facing the inner cavity of the housing body 100 and / or away from the inner cavity of the housing body 100. The liquid storage chamber and heat dissipation pipes are connected in series to form the first channel 201, which can effectively extend the length of the first channel 201 and increase the heat dissipation area, thereby enhancing the heat dissipation effect. The series connection sequence of the liquid storage chamber and heat dissipation pipes with the cooling medium supply device 300, the internal heat dissipation pipes, and the heat exchanger 410 can be adjusted according to actual conditions.

[0081] In some embodiments, the housing body 100 further includes a protective plate 700, which is connected to the first side plate, and a first flow pipe 200 is disposed between the first side plate and the protective plate 700. The protective plate 700 is used to protect the first flow pipe 200 and enhance the structural strength of the housing body 100. For example, in combination with... Figure 18The first side plate is a corrugated plate structure, and the protective plate 700 is also a corrugated plate structure. The two corrugated plates have the same structure and are arranged symmetrically to arrange the first flow pipe 200 through the space between the two corrugated plate structures. This structure can effectively widen the flow area of ​​the cooling medium, thereby reducing flow resistance and improving heat exchange efficiency.

[0082] In some embodiments, combined with Figure 1 and Figure 2 The first side plate or the first flow pipe 200 is a corrugated plate structure. The corrugated plate structure has a corrugated plate flow channel. The corrugated plate flow channel can be used as the first channel 201 for heat exchange. In addition, the corrugated plate flow channel has structural strength, protection and heat dissipation performance, which can improve the space utilization of the energy storage box.

[0083] Combination Figure 3 and Figure 4 The first side plate or first flow pipe 200 may specifically include one or more corrugated plate pieces connected together, each corrugated plate piece having the aforementioned first channel 201. By combining different numbers of corrugated plate pieces, the required length of the first channel 201 can be obtained, increasing the flexibility of structural configuration and facilitating adaptation to the heat exchange requirements of different energy storage boxes. Specifically, multiple corrugated plate pieces can be fixedly connected or detachably connected.

[0084] Further optimize the plan, combined with Figure 5 and Figure 8 A heat sink 500 is provided on the outer wall surface of the first side plate or the first flow pipe 200. The specific structure of the heat sink is not limited; it can be a single flat fin disposed on the outer wall surface of the first side plate or the first flow pipe 200, or the heat sink can be mounted on the outer wall surface of the first side plate or the first flow pipe 200 via a substrate, or a heat sink with multiple heat pipes can be disposed on the outer wall surface of the first side plate or the first flow pipe 200 via a substrate. The heat sink 500 can further increase the heat exchange area, improve the heat dissipation capacity of the first side plate, thereby improving heat dissipation efficiency and reducing heat dissipation costs. The outer wall surface of the first side plate or the first flow pipe 200 can be the side facing the inner cavity of the housing body 100 or the side facing away from the inner cavity of the housing body 100.

[0085] Combination Figure 14 and Figure 15The enclosure body 100 includes a second side plate connected to the first side plate and has a second channel for the passage of cooling medium. The second channel is connected in series with the first channel 201 and the cooling medium supply device 300. Specifically, the bottom plate of the enclosure body 100 can serve as the aforementioned second side plate. Due to the sinking effect of cold air, the bottom ambient temperature of the enclosure body 100 is relatively lower and less affected by solar radiation, thus resulting in stronger heat exchange performance and effectively improving heat dissipation efficiency.

[0086] The second channel can be directly installed on the second side plate, or a second flow pipe 210 can be installed inside the second side plate and / or on its outer wall. The second flow pipe 210 forms the second channel. The second flow pipe 210 and the second side plate can be an integral or separate structure. The second flow pipe 210 can be embedded inside the second side plate or fitted to its outer wall. The outer wall of the second side plate can be the side facing the inner cavity of the housing body 100 or the side facing away from the inner cavity of the housing body 100. When the aforementioned second flow pipe 210 is installed on both the inner and outer walls of the second side plate, the heat exchange area can be effectively increased and the heat exchange efficiency improved. The types of the second channel include, but are not limited to, corrugated plate channels, wire tube channels, and liquid storage cavities. The structure of the second flow pipe 210 and the first flow pipe 200 can be the same or different, and the structures of the first side plate and the second side plate can be the same or different. The joint installation of the first channel 201 and the second channel can effectively improve heat dissipation efficiency and reduce heat dissipation costs.

[0087] Wherein, if the first outlet 203 of the first channel 201 is connected to the second inlet of the second channel, the first outlet 203 of the first channel 201 can be set on the side of the first side plate near the second side plate, and the second inlet of the second channel can be set on the side of the second side plate near the first side plate; if the first inlet 202 of the first channel 201 is connected to the second outlet of the second channel, the first inlet 202 of the first channel 201 can be set on the side of the first side plate near the second side plate, and the second outlet of the second channel can be set on the side of the second side plate near the first side plate, so as to facilitate the connection between the first channel 201 and the second channel.

[0088] The series connection of the aforementioned internal heat dissipation pipes, first channel 201, second channel, and heat exchanger 410 can be adjusted as needed. In some embodiments, taking the cooling medium supply device 300 as the starting point, along the flow direction of the cooling medium, the outlet of the internal heat dissipation pipe is connected to the inlet of the first channel 201 or the second channel, and the heat exchanger 410 is connected to the outlet of the first channel 201 or the second channel. The first channel 201 and the second channel are connected in series, and their relative positions can be interchanged to ensure the natural heat dissipation efficiency of the first channel 201 and the second channel. For example, in a specific heat dissipation process, combined with... Figure 15 After the cooling medium exchanges heat with the heat-generating components inside the housing 100 through the internal heat dissipation pipes, it undergoes heat dissipation three times in sequence at the first channel 201, the second channel, and the heat exchanger 410, which greatly improves the heat exchange efficiency.

[0089] Combination Figure 16 and Figure 17 The enclosure body 100 also includes an insulation layer 103, which is used to reduce the impact of heat from the external environment on the heating elements inside the enclosure body 100. The first side plate can be set inside the insulation layer 103 to enhance the heat absorption capacity of the first channel 201 to the internal environment of the enclosure body 100 and absorb the heat from the heating elements. Alternatively, the first side plate can be set outside the insulation layer 103 to facilitate the first channel 201 to dissipate heat to the external environment, improve heat dissipation efficiency, and take into account both the aesthetics and practicality of the design.

[0090] Furthermore, a heat-conducting medium is filled between the first flow pipe 200 and the first side plate. The heat-conducting medium can be a thermal interface material, a phase change material, etc. This medium has good thermal conductivity and can reduce heat transfer resistance, thereby enhancing heat exchange capacity. A heat-conducting medium can also be placed between the second flow pipe 210 and the second side plate to reduce thermal resistance and enhance heat exchange capacity.

[0091] In some embodiments, combined with Figure 19 and Figure 20 The energy storage box also includes a spray device 600. The spray nozzles of the spray device 600 are arranged facing the first side plate and / or the first channel 201 and away from the outer wall of the inner cavity of the box body 100. The spray device 600 can be set to start at a fixed time to remove dust and cool down, so as to ensure the heat dissipation capacity and service life of the energy storage box.

[0092] The energy storage device disclosed in this application includes a heating element, an internal heat dissipation pipe, and the aforementioned energy storage housing. Both the heating element and the internal heat dissipation pipe are housed within the housing body 100. The internal heat dissipation pipe is connected in series with the first channel 201 and the cooling medium supply device 300. The cooling medium, supplied by the cooling medium supply device 300, flows sequentially through the internal heat dissipation pipe and the first channel 201, thereby absorbing heat dissipated by the heating element and dissipating it to the external environment. Since it includes the aforementioned energy storage housing, it also possesses the aforementioned structure and beneficial effects. Other structural details are based on existing technology and will not be elaborated upon here.

[0093] In some embodiments, combined with Figure 1The housing body 100 includes a third side plate connected to the first side plate. The energy storage device also includes an air-cooling assembly, which includes a heat exchanger 410 and a fan 400. The heat exchanger 410 is mounted on the third side plate and connected in series with the first channel 201 and the cooling medium supply device 300. The fan 400 is mounted on the third side plate or the heat exchanger 410, with its air outlet facing the heat exchanger 410. The cooling medium, after initial heat dissipation through the first channel 201, can undergo secondary heat exchange at the heat exchanger 410. In addition, when heat dissipation requirements are high, the fan 400 can be activated to improve the heat dissipation efficiency of the heat exchanger 410, thereby ensuring the normal operation of the heat-generating components and other electronic devices inside the housing body 100. The top plate of the housing body 100 can serve as the aforementioned third side plate to ensure the heat exchange performance between the heat exchanger 410 and the external environment.
