To quickly cool these devices, cooling fans are typically installed inside the cabinet. However, this cooling method takes a long time to achieve complete cooling, resulting in low cooling efficiency. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a cabinet and an energy storage device, aiming to solve the technical problem of low cooling efficiency of electronic equipment installed inside the cabinet in the related art.

[0004] To achieve the above-mentioned purpose, according to one aspect of the present application, a cabinet is provided, including: a cabinet body, the cabinet body having an installation space; a partition, installed in the installation space, and dividing the installation space into a first installation cavity and a second installation cavity, the first installation cavity can be installed with a first component, and the second installation cavity can be installed with a second component; a first heat dissipation member, installed on the cabinet body, for conducting heat in the first installation cavity to the outside of the first installation cavity; a second heat dissipation member, installed on the cabinet body, for conducting heat in the second installation cavity to the outside of the second installation cavity.

[0005] When the first component and the second component installed in the cabinet of the present application are cooled, the first heat sink will cool the first component installed in the first installation cavity by transferring the heat in the first installation cavity to the outside of the first installation cavity. At the same time, the second heat sink will cool the second component installed in the second installation cavity by transferring the heat in the second installation cavity to the outside of the second installation cavity. The above-mentioned cooling method can enable the first component and the second component to be cooled separately and synchronously, which is not only conducive to shortening the time required for cooling the first component and the second component, improving the cooling efficiency, but also conducive to reducing the possibility of local overheating. In addition, the above-mentioned heat dissipation method is also conducive to separate temperature adjustment of the first component and the second component, improving the flexibility of the cooling operation. In addition, the provision of the first installation cavity and the second installation cavity is not only conducive to blocking the flow and transmission of heat between the first installation cavity and the second installation cavity, shortening the time required for cooling the first component and the second component, reducing the possibility of local heat accumulation, but also plays a role in isolating the first component and the second component, so that the first component and the second component do not interfere with each other, thereby enhancing the safety of the first component and the second component.

[0006] Optionally, a first air inlet and a first air outlet are provided on the cabinet body, the first air outlet is located on one side of the first air inlet, the first air inlet is connected to the first installation cavity, and the first air outlet is connected to the first installation cavity; the first heat dissipation element has an air outlet end, the air outlet end is connected to the first air inlet, and air can be introduced into the first installation cavity through the first air inlet.

[0007] When the first component is cooled, the air outlet end of the first heat sink introduces air into the first installation cavity through the first air inlet. After the air enters the first installation cavity, it exchanges heat with the heat generated by the first component. At the same time, the air in the first installation cavity will be discharged outward through the first air outlet. As the air continues to be introduced, the temperature of the first component will also decrease accordingly.

[0008] Optionally, the first heat sink further has an air suction end, which is connected to the first air outlet and can suck the air in the first installation cavity outward; and / or, the first air outlet is located below the first air inlet.

[0009] When the first component is cooled, the air outlet of the first heat sink introduces air into the first installation cavity through the first air inlet. After the air enters the first installation cavity, it exchanges heat with the heat generated by the first component. At the same time, the air intake of the first heat sink draws the air in the first installation cavity out of the first installation cavity. The provision of the air intake accelerates the flow rate of the air in the first installation cavity and increases the cooling rate of the first component. In addition, the design of the first air outlet being located below the first air inlet complies with the law of natural convection, which not only helps to improve the heat exchange efficiency, thereby increasing the cooling rate of the first component, but also effectively reduces energy consumption.

[0010] Optionally, the cabinet also includes an installation frame, which is installed in the first installation cavity; the installation frame has a storage space capable of accommodating the first component; the installation frame is provided with an air inlet and an air outlet, the air inlet and the air outlet are arranged opposite to each other, the first installation cavity is connected to the storage space through the air inlet, and the first air outlet is connected to the storage space through the air outlet.

[0011] When the first component is cooled, the outlet end of the first heat sink draws air into the first mounting cavity through the first air inlet. After entering the first mounting cavity, the air flows through the air inlet into the mounting space, thereby cooling the first component. Simultaneously, the air in the accommodation space is drawn out of the first mounting cavity by the air intake end of the heat sink through the first air outlet. The mounting frame not only protects the first component but also helps guide air flow within the first mounting cavity, thereby effectively cooling the first component.

[0012] Optionally, there are multiple air inlet holes, and the multiple air inlet holes are arranged at intervals along the length direction of the first component.

[0013] The multiple air inlet holes are conducive to the first component being in contact with the air entering the accommodating space, thereby achieving synchronous cooling to avoid local overheating and the like.

[0014] Optionally, the first installation cavity has an upper cavity wall, a first side cavity wall and a second side cavity wall, a first air duct for air flow is provided between the installation frame and the upper cavity wall, and the first air inlet is connected to the first air duct; the first side cavity wall is arranged adjacent to the upper cavity wall, a second air duct for air flow is provided between the installation frame and the first side cavity wall, the second air duct is connected to the first air duct, and is connected to the accommodating space through the air inlet hole; the second side cavity wall is arranged adjacent to the upper cavity wall, the second side cavity wall is arranged opposite to the first side cavity wall, and the first air inlet and the first air outlet are both arranged on the second side cavity wall.

[0015] When the first component is cooled, the air outlet end of the heat sink introduces air into the first installation cavity through the first air inlet. The air passes through the first air duct and the second air duct in sequence and then enters the storage space through the air inlet to cool the first component in the storage space. The air in the storage space is discharged to the outside of the first installation cavity through the first air outlet. The first and second air ducts are arranged in accordance with the law of natural convection, which not only provides a guiding effect for the air, so that the cooling space can flow quickly and accurately into the storage space, but also effectively reduces energy consumption. In addition, the design of the second side cavity wall being arranged relative to the first side cavity wall is conducive to the first component being fully in contact with the air introduced into the storage space, effectively improving the cooling speed of the first component.

[0016] Optionally, the mounting frame is mounted on the partition; the first mounting cavity also has a third side cavity wall and a fourth side cavity wall, the third side cavity wall is arranged adjacent to the upper cavity wall and adjacent to the first side cavity wall, and the mounting frame remains in contact with the third side cavity wall; the fourth side cavity wall is arranged opposite to the third side cavity wall, and the mounting frame remains in contact with the fourth side cavity wall.

[0017] The mounting frame designed as above allows air to enter the accommodation space through the air inlet only after passing through the first air duct and the second air duct in sequence, thereby effectively improving the utilization rate of air.

[0018] Optionally, the cabinet further includes a cabinet door, the installation space has an opening, the cabinet door is installed on the cabinet body and can block the opening; the second air duct is provided between the cabinet door and the installation frame.

[0019] The cabinet door is not only conducive to installing the first component and the second component into the first installation cavity and the second installation cavity respectively, but also conducive to taking the first component and the second component out of the first installation cavity and the second installation cavity respectively.

[0020] Optionally, a second air inlet and a second air outlet are provided on the cabinet body, and the second air inlet and the second air outlet are both connected to the second installation cavity, and the second air outlet is arranged opposite to the second air inlet; the second heat sink is installed in the second installation cavity, and the second heat sink can suck the air outside the second installation cavity into the second installation cavity through the second air inlet, and can discharge the air in the second installation cavity to the outside of the second installation cavity through the second air outlet; and / or, the second installation cavity is located below the first installation cavity.

[0021] When the second component is cooled, the second heat sink draws the air outside the second installation cavity into the second installation cavity through the second air inlet, and the air drawn into the second installation cavity exchanges heat with the heat generated by the second component. At the same time, the second heat sink discharges the air in the second installation cavity to the outside of the second installation cavity through the second air outlet. As the air outside the second installation cavity is continuously drawn into the second installation cavity, the temperature of the second component will also decrease. The design in which the second air outlet and the second air inlet are arranged relative to each other is conducive to full contact between the air drawn into the second installation cavity of the second component, thereby facilitating an increase in the cooling rate of the second component. In addition, the design in which the second installation cavity is located below the first installation cavity complies with the principle of natural convection, which not only helps to improve the heat exchange efficiency, thereby increasing the cooling rate of the first and second components, but also effectively reduces energy consumption.

[0023] The provision of the first mounting cavity and the second mounting cavity not only helps to block the flow and propagation of heat between the first mounting cavity and the second mounting cavity, shortens the time required for cooling the battery and electrical parts, and reduces the possibility of local heat accumulation, but also serves to isolate the battery and electrical parts, so that the battery and electrical parts do not interfere with each other, thereby enhancing the safety of the battery and electrical parts.

[0024] The cabinet provided by the present application has the following beneficial effects: when the first component and the second component installed in the cabinet of the present application are cooled, the first heat sink will cool the first component installed in the first installation cavity by transferring the heat in the first installation cavity to the outside of the first installation cavity, and at the same time, the second heat sink will cool the second component installed in the second installation cavity by transferring the heat in the second installation cavity to the outside of the second installation cavity; the above-mentioned cooling method can enable the first component and the second component to be cooled separately and synchronously, which not only helps to shorten the time required for cooling the first component and the second component, improve the cooling efficiency, but also helps to reduce the possibility of local overheating; in addition, the above-mentioned heat dissipation method is also conducive to adjusting the temperature of the first component and the second component separately, thereby improving the flexibility of the cooling operation.

[0042] As described in the background, a cabinet is a sealed metal box used to store various electronic devices. In related art, a cabinet typically houses multiple electronic devices. To quickly cool these devices, a cooling fan is typically installed inside the cabinet. However, this cooling method takes a long time to achieve complete cooling, resulting in low cooling efficiency.

[0043] Reference Figures 1 to 4 In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a cabinet, which includes a cabinet body 110, a partition 200, a first heat dissipation member 500 and a second heat dissipation member 600, wherein the cabinet body 110 has an installation space 111; the partition 200 is installed in the installation space 111, and divides the installation space 111 into a first installation cavity 1111 and a second installation cavity 1112, the first installation cavity 1111 can be installed with a first component 300, and the second installation cavity 1112 can be installed with a second component 400; the first heat dissipation member 500 is installed on the cabinet body 110, and is used to conduct heat in the first installation cavity 1111 to the outside of the first installation cavity 1111; the second heat dissipation member 600 is installed on the cabinet body 110, and is used to conduct heat in the second installation cavity 1112 to the outside of the second installation cavity 1112.

[0044] In this embodiment, the cabinet 110 is generally made of steel plate or aluminum alloy, and the interior of the cabinet 110 is hollow to form an installation space 111; the partition 200 is generally fixedly installed in the installation space 111 to divide the installation space 111 into a first installation cavity 1111 and a second installation cavity 1112 that do not interfere with each other. In other embodiments, the partition 200 can also slide in the installation space 111 along the vertical direction to adjust the space size of the first installation cavity 1111 and the second installation cavity 1112; the first component 300 is installed in the first installation cavity 1111, and the first component 300 is generally a battery component capable of storing and releasing electrical energy; the second component 400 is installed in the second installation cavity 1112, and the second component 400 is generally an electrical component for controlling the battery component, and the electrical component is generally a power conditioning system (full name in English: Power Conditioning System, English abbreviation: PCS), and the second component 400 is generally electrically connected to the first component 300; the structure of the first heat sink 500 and the structure of the second heat sink 600 can be the same or different.

[0045] When the first component 300 and the second component 400 installed inside the cabinet of the present application are cooled, the first heat dissipation member 500 will cool the first component 300 installed in the first installation cavity 1111 by transferring the heat in the first installation cavity 1111 to the outside of the first installation cavity 1111. At the same time, the second heat dissipation member 600 will cool the second component 400 installed in the second installation cavity 1112 by transferring the heat in the second installation cavity 1112 to the outside of the second installation cavity 1112. The above-mentioned cooling method can enable the first component 300 and the second component 400 to be cooled separately and synchronously, which is not only conducive to shortening the time required for cooling the first component 300 and the second component 400 and improving the cooling efficiency, but also conducive to reducing the possibility of local overheating. In addition, the above-mentioned heat dissipation method is also conducive to separate temperature adjustment of the first component 300 and the second component 400, thereby improving the flexibility of the cooling operation. In addition, the provision of the first installation cavity 1111 and the second installation cavity 1112 is not only conducive to blocking the flow and propagation of heat between the first installation cavity 1111 and the second installation cavity 1112, shortening the time required for the first component 300 and the second component 400 to cool down, and reducing the possibility of local heat accumulation, but also serves to isolate the first component 300 and the second component 400, so that the first component 300 and the second component 400 do not interfere with each other, thereby enhancing the safety of the first component 300 and the second component 400.

[0046] Reference Figure 2 and Figure 3In one embodiment, a first air inlet 112 and a first air outlet 113 are provided on the cabinet 110. The first air outlet 113 is located on one side of the first air inlet 112. The first air inlet 112 is communicated with the first installation cavity 1111, and the first air outlet 113 is communicated with the first installation cavity 1111. The first heat dissipation element 500 has an air outlet end, which is communicated with the first air inlet 112 and can allow air to enter the first installation cavity 1111 through the first air inlet 112.

[0047] In this embodiment, the first heat sink 500 is usually an air conditioner. The first heat sink 500 is usually fixedly mounted on the outer surface of the cabinet 110. The air introduced into the first installation cavity 1111 from the air outlet of the first heat sink 500 is cooling air. The temperature of the cooling air is usually lower than the temperature of the air in the first installation cavity 1111. In other embodiments, the first heat sink 500 can also be a heat pump system, a heat exchanger, or a thermoelectric refrigeration plate. When the first component 300 is cooled, the air outlet of the first heat sink 500 introduces cooling air into the first installation cavity 1111 through the first air inlet 112. After the cooling air enters the first installation cavity 1111, it exchanges heat with the heat generated by the first component 300. At the same time, the air in the first installation cavity 1111 is discharged outward through the first air outlet 113. As the cooling air continues to be introduced, the temperature of the first component 300 will also decrease. Figure 2 The direction of the black arrow is the flow direction of the air from the air outlet end of the first heat dissipation element 500 into the first installation cavity 1111 .

[0048] Reference Figure 2 and Figure 3 In one embodiment, the first heat sink 500 further has an air suction end, which is connected to the first air outlet 113 and can suck the air in the first installation cavity 1111 outward.

[0049] In this embodiment, the air intake and air outlet are typically located on the same side of the cabinet 110. When the first component 300 is cooled, the air outlet of the first heat sink 500 introduces cooling air into the first installation cavity 1111 through the first air inlet 112. After entering the first installation cavity 1111, the cooling air exchanges heat with the heat generated by the first component 300. Simultaneously, the air intake of the first heat sink 500 draws air from the first installation cavity 1111 out of the first installation cavity 1111. The provision of the air intake accelerates the flow of air within the first installation cavity 1111, thereby increasing the cooling rate of the first component 300.

[0050] Reference Figure 2In one embodiment, the first air outlet 113 is located below the first air inlet 112. The above design complies with the law of natural convection, which not only helps to improve the heat exchange efficiency, thereby increasing the cooling speed of the first component 300, but also effectively reduces energy consumption.

[0051] Reference Figures 2 to 4 In one embodiment, the cabinet further includes an installation frame 700, which is installed in the first installation cavity 1111; the installation frame 700 has a receiving space 710 capable of receiving the first component 300, and the first component 300 is installed in the receiving space 710; the installation frame 700 is provided with an air inlet 720 and an air outlet, the first installation cavity 1111 is connected to the receiving space 710 through the air inlet 720, and the first air outlet 113 is connected to the receiving space 710 through the air outlet.

[0052] In this embodiment, the mounting frame 700 is typically fixedly mounted within the first mounting cavity 1111, and the air outlet and the first air outlet 113 are the same opening. When the first component 300 is cooled, the air outlet end of the first heat sink 500 introduces cooling air into the first mounting cavity 1111 through the first air inlet 112. After the cooling air enters the first mounting cavity 1111, it enters the mounting space 111 through the air inlet 720 to cool the first component 300. At the same time, the air within the accommodating space 710 is sucked out of the first mounting cavity 1111 by the air intake end of the first heat sink 500 through the first air outlet 113. The mounting frame 700 not only provides protection for the first component 300, but also helps guide air flow within the first mounting cavity 1111, thereby better cooling the first component 300.

[0053] Reference Figures 2 to 4 In one embodiment, the air inlet 720 is disposed opposite to the air outlet. This design facilitates full contact between the first component 300 and the air entering the accommodation space 710, further increasing the cooling speed of the first component 300.

[0054] Reference Figures 2 to 4 In one embodiment, there are multiple air inlet holes 720 , and the multiple air inlet holes 720 are spaced apart along the length direction of the first component 300 .

[0055] In this embodiment, the first component 300 generally includes a plurality of battery packs 310 spaced apart along a vertical direction. The length of the first component 300 is parallel to the vertical direction. Each of the battery packs 310 is provided in a one-to-one correspondence with a plurality of air inlet holes 720. The specific structure of the battery packs 310 is common knowledge among those skilled in the art and will not be elaborated upon here. In other embodiments, the battery packs 310 may be spaced apart along a direction that is angled with the vertical direction. The plurality of air inlet holes 720 facilitates simultaneous contact between the battery packs 310 and the air entering the accommodation space 710, thereby achieving simultaneous cooling and preventing localized overheating. Furthermore, the first component 300 also includes a power distribution unit 320 (PDU), which is located below the bottommost battery pack 310. Each of the battery packs 310 is electrically connected to the power distribution unit 320.

[0056] Reference Figures 2 to 4 In one embodiment, the first installation cavity 1111 has an upper cavity wall, a first side cavity wall and a second side cavity wall, a first air duct 730 for air flow is provided between the installation frame 700 and the upper cavity wall, and the first air inlet 112 is connected to the first air duct 730; the first side cavity wall is adjacent to the upper cavity wall, a second air duct 740 for air flow is provided between the installation frame 700 and the first side cavity wall, the second air duct 740 is connected to the first air duct 730, and is connected to the accommodating space 710 through the air inlet hole 720; the second side cavity wall is adjacent to the upper cavity wall, and the first air inlet 112 and the first air outlet 113 are both provided on the second side cavity wall.

[0057] In this embodiment, the first installation cavity 1111 is shaped like a cuboid. In other embodiments, the first installation cavity 1111 can also be shaped like a cylinder, a cube, or a sphere. The first air inlet 112 and the first air outlet 113 are both through-holes. When the first component 300 is cooled, the outlet end of the heat sink introduces cooling air into the first installation cavity 1111 through the first air inlet 112. The cooling air passes through the first air duct 730 and the second air duct 740 in sequence and then enters the storage space 710 through the air inlet 720 to cool the first component 300 in the storage space 710. The air in the storage space 710 is discharged to the outside of the first installation cavity 1111 through the first air outlet 113. The first air duct 730 and the second air duct 740 conform to the law of natural convection, which not only guides the cooling air, allowing the cooling air to flow quickly and accurately into the storage space 710, but also effectively reduces energy consumption.

[0058] Reference Figures 2 to 4In one embodiment, the second side cavity wall is disposed opposite the first side cavity wall. This design facilitates sufficient contact between the first component 300 and the air entering the accommodation space 710, effectively increasing the cooling rate of the first component 300. In other embodiments, the second side cavity wall may also be disposed adjacent to the first side cavity wall.

[0059] Reference Figures 2 to 4 In one embodiment, the mounting frame 700 is mounted on the partition 200; the first mounting cavity 1111 further has a third side cavity wall and a fourth side cavity wall, the third side cavity wall is adjacent to the upper cavity wall and adjacent to the first side cavity wall, and the mounting frame 700 remains in contact with the third side cavity wall; the fourth side cavity wall is opposite to the third side cavity wall, and the mounting frame 700 remains in contact with the fourth side cavity wall.

[0060] In this embodiment, the mounting frame 700 is in close contact with the partition 200 to prevent air from flowing through the gap between the mounting frame 700 and the partition 200. The fourth side cavity wall is positioned adjacent to the upper cavity wall and adjacent to the first side cavity wall. This configuration of the mounting frame 700 allows cooling air to flow only through the first air duct 730 and the second air duct 740 before entering the accommodation space 710 through the air inlet 720, effectively improving the utilization rate of the cooling air.

[0061] Reference Figures 1 to 3 In one embodiment, the cabinet further includes a cabinet door 120 , the installation space 111 has an opening, the cabinet door 120 is installed on the cabinet body 110 and can block the opening; the second air duct 740 is provided between the cabinet door 120 and the installation frame 700 .

[0062] In this embodiment, the cabinet door 120 is hingedly mounted on the cabinet body 110. The connection method between the cabinet door 120 and the cabinet body 110 is common knowledge to those skilled in the art and will not be elaborated on in detail here. The cabinet door 120 has a closed state and an open state. When the cabinet door 120 is in the closed state, the area between the surface of the cabinet door 120 close to the cabinet body 110 and the installation frame 700 is formed as a second air duct 740, and the surface of the cabinet door 120 close to the cabinet body 110 is formed as a second side cavity wall. At the same time, the surface of the partition 200 close to the cabinet door 120 is kept in contact with the surface of the cabinet door 120 close to the cabinet body 110, so that the first installation cavity 1111 and the second installation cavity 1112 do not interfere with each other. The provided cabinet door 120 is not only conducive to installing the first component 300 and the second component 400 into the first installation cavity 1111 and the second installation cavity 1112 respectively, but also facilitates taking the first component 300 and the second component 400 out of the first installation cavity 1111 and the second installation cavity 1112 respectively.

[0063] Reference Figure 1 and Figure 2In one embodiment, a second air inlet 114 and a second air outlet 115 are provided on the cabinet 110, and the second air inlet 114 and the second air outlet 115 are both communicated with the second installation cavity 1112, and the second air outlet 115 is arranged opposite to the second air inlet 114; the second heat sink 600 is installed in the second installation cavity 1112, and the second heat sink 600 can suck the air outside the second installation cavity 1112 into the second installation cavity 1112 through the second air inlet 114, and can discharge the air in the second installation cavity 1112 to the outside of the second installation cavity 1112 through the second air outlet 115.

[0064] In this embodiment, the second heat sink 600 is a cooling fan fixedly mounted within the second mounting cavity 1112. When the second component 400 is cooled, the second heat sink 600 draws air from outside the second mounting cavity 1112 into the second mounting cavity 1112 through the second air inlet. The air drawn into the second mounting cavity 1112 exchanges heat with the heat generated by the second component 400. Simultaneously, the second heat sink 600 discharges the air from the second mounting cavity 1112 out of the second mounting cavity 1112 through the second air outlet. As air from outside the second mounting cavity 1112 is continuously drawn into the second mounting cavity 1112, the temperature of the second component 400 decreases. The relative positioning of the second air outlet 115 and the second air inlet 114 facilitates full contact between the second component 400 and the air drawn into the second mounting cavity 1112, thereby accelerating the cooling rate of the second component 400. In addition, the second air inlet 114 is usually provided on the cabinet door 120 ; in order to reduce external dust or debris from entering the second installation cavity 1112 , shutters are installed on the cabinet body 110 , and the shutters block the second air outlet 115 .

[0065] Reference Figures 2 to 4 In one embodiment, the second installation cavity 1112 is located below the first installation cavity 1111. The above design complies with the principle of natural convection, which not only helps to improve the heat exchange efficiency, thereby increasing the cooling rate of the first component 300 and the second component 400, but also effectively reduces energy consumption.

[0066] Reference Figures 1 to 4 According to another aspect of the present application, an embodiment of the present application further provides an energy storage device, which includes a battery part, an electrical part and the above-mentioned cabinet, the battery part is installed in the first installation cavity 1111, and the electrical part is installed in the second installation cavity 1112. The battery part is formed as a first component 300, and the electrical part is formed as a second component 400.

[0067] The provision of the first mounting cavity 1111 and the second mounting cavity 1112 is not only conducive to blocking the flow and propagation of heat between the first mounting cavity 1111 and the second mounting cavity 1112, shortening the time required for cooling the battery and electrical parts and reducing the possibility of local heat accumulation, but also serves to isolate the battery and electrical parts, so that the battery and electrical parts do not interfere with each other, thereby enhancing the safety of the battery and electrical parts.

[0068] In summary, the cabinet and energy storage device provided by the present embodiment have at least the following beneficial technical effects: when the first component 300 and the second component 400 installed inside the cabinet of the present application are cooled, the first heat dissipation member 500 will cool the first component 300 installed in the first installation cavity 1111 by transferring the heat in the first installation cavity 1111 to the outside of the first installation cavity 1111. At the same time, the second heat dissipation member 600 will cool the second component 400 installed in the second installation cavity 1112 by transferring the heat in the second installation cavity 1112 to the outside of the second installation cavity 1112. The above-mentioned cooling method can enable the first component 300 and the second component 400 to be cooled separately and synchronously, which is not only conducive to shortening the time required for cooling the first component 300 and the second component 400 and improving the cooling efficiency, but also conducive to reducing the possibility of local overheating. In addition, the above-mentioned heat dissipation method is also conducive to separate temperature adjustment of the first component 300 and the second component 400, thereby improving the flexibility of the cooling operation. In addition, the provision of the first installation cavity 1111 and the second installation cavity 1112 is not only conducive to blocking the flow and propagation of heat between the first installation cavity 1111 and the second installation cavity 1112, shortening the time required for the first component 300 and the second component 400 to cool down, and reducing the possibility of local heat accumulation, but also serves to isolate the first component 300 and the second component 400, so that the first component 300 and the second component 400 do not interfere with each other, thereby enhancing the safety of the first component 300 and the second component 400.

[0069] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
