[0045] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0049] This application provides a thermal management unit capable of being configured to perform thermal management on equipment (e.g., energy storage equipment). For example, the thermal management unit can be suspended from the side wall of the equipment, or it can be at least partially embedded in the side wall of the equipment. The thermal management unit includes a cabinet structure, a heat exchange system, and a main control board. The cabinet structure forms the external shape of the thermal management unit and is used to install and fix the unit. The heat exchange system is at least partially housed inside the cabinet structure and is used to provide a reliable temperature environment for the equipment. The main control board is housed inside the cabinet structure and is used to control the operation of the heat exchange system.

[0050] like Figures 1-5 As shown, the cabinet structure provided in this application embodiment includes a cabinet body 1, a cabinet door 2, and a first cavity 8. The cabinet body 1 and the cabinet door 2 enclose an internal space for the cabinet body 1, which is used to store a heat exchange system. That is, at least a part of the heat exchange system can be accommodated in the internal space of the cabinet body 1. The first cavity 8 is separated from the internal space of the cabinet body 1 and is used to store electronic equipment such as the main control board.

[0051] Furthermore, the cabinet 1 includes a first side 11 and a second side 12, which are arranged back-to-back. The cabinet 1 has a first opening 111 on the first side 11, which connects to the internal space of the cabinet 1. The cabinet door 2 is detachably connected to the cabinet 1 to close or open the first opening 111. That is, the user can open the cabinet door 2 on the first side 11 to maintain the heat exchange system stored in the internal space of the cabinet 1. The first cavity 8 is located on the second side 12 of the cabinet 1 and is configured to be recessed into the interior of the cabinet 1 along the second side 12. That is, the sealing surface between the first cavity 8 and the cabinet 1 is located on the second side 12. Therefore, when the user opens the cabinet door 2 on the first side 11, the sealing state between the first cavity 8 and the cabinet 1 is not affected. Thus, it can effectively prevent liquid from entering the first cavity 8 during the maintenance of the heat management unit, which could damage the main control board and other electronic equipment, thereby ensuring the reliable operation of the equipment.

[0052] During the operation of the thermal management unit, condensation or rainwater ingress is inevitable inside cabinet 1. Since the energy storage device contains energy storage cells, water ingress can lead to safety accidents. Therefore, strict control over the sealing of the energy storage device's interior is crucial. However, due to the high pressure caused by the fan system during operation, the energy storage device's interior is relatively low-pressure. If the first side 11, facing the interior of the energy storage device, is exposed to drafts, in related technologies, the installation and maintenance ports and electrical control box of the thermal management unit are located on the side facing the interior of the energy storage device, i.e., the first side 11, and are equipped with removable covers. During installation, the covers are opened... After installation or maintenance is completed, the cover is closed and sealed with sealant or gasket. However, this method carries the risk of seal failure, and each maintenance requires resealing, which is time-consuming and labor-intensive. In this embodiment, the first side 11 does not have a maintenance port, but the maintenance port is located on the second side 12, that is, exposed on the other side of the energy storage device. Maintenance can be performed on the outside, which is more convenient. At the same time, the first side 11 is an integrated structure, including the electrical control box. It can be formed by integral sheet metal bending, welding, stamping, or die casting. The integrated structure has a higher sealing level and can effectively improve the problem of water ingress into the energy storage device.

[0053] Specifically, the first side 11 is the side of the thermal management unit that is away from the equipment when it is installed, and the second side 12 is the side of the thermal management unit that is facing the equipment when it is installed, so that the cabinet door 2 is exposed to the outside of the equipment, thereby enabling the thermal management unit to be maintained from the outside of the equipment and improving the convenience of thermal management unit maintenance.

[0054] The cabinet 1 also includes a wall portion 13 protruding along the depth direction of the cabinet 1 (i.e., the direction from the first side 11 to the second side 12) to ensure that the internal space of the cabinet 1 meets the usage requirements. The outer surface of the wall portion 13 is provided with a connecting flange 14, which is used to connect to the equipment to achieve the installation and fixation of the thermal management unit. The connecting flange 14 and the cabinet 1 can be connected to each other by a detachable method such as bolts, or they can be connected to each other by a non-detachable method such as welding.

[0055] Furthermore, the first cavity 8 and the cabinet 1 are an integral structure to ensure that the first cavity 8 and the cabinet 1 form a non-removable connection, thereby ensuring a reliable sealing state between the first cavity 8 and the cabinet 1 and preventing liquid from the internal space of the cabinet 1 from penetrating into the first cavity 8.

[0056] In one embodiment, the first cavity portion 8 and the cabinet 1 are integrally molded to form an integrated structure. The first cavity portion 8 and the cabinet 1 form a smooth, seamless connection on the second side 12, which not only ensures a reliable seal between the first cavity portion 8 and the cabinet 1, but also improves the appearance of the cabinet structure. For example, die casting, sheet metal, or stamping processes can be used to directly recess the surface of the cabinet 1 on the second side 12 into the interior of the cabinet 1, forming the cabinet 1 with the first cavity portion 8.

[0057] In another embodiment, the first cavity 8 and the cabinet 1 are joined into a single structure by a non-removable method such as welding. The first cavity 8 and the cabinet 1 are formed separately, which simplifies the structure of the molding die and reduces potential defects in the molding process. For example, the first cavity 8 and the cabinet 1 are formed by die casting, sheet metal, or stamping processes, and then joined into a single structure by welding or other methods.

[0058] Specifically, when the first cavity portion 8 and the cabinet 1 are respectively formed and connected to each other (including detachable and non-detachable connections) to form a sealed state, the cabinet 1 has a second opening 121 on the second side 12. The size and shape of the second opening 121 are adapted to the shape of the first cavity portion 8. The first cavity portion 8 is disposed at the second opening 121, and the first cavity portion 8 is recessed from the second side 12 to the first side 11 of the cabinet 1, so that at least a portion of the first cavity portion 8 extends into the internal space of the cabinet 1 through the second opening 121, thereby giving the cabinet structure a regular overall shape.

[0059] Furthermore, the first cavity 8 is provided with a cover, which is detachably connected to the first cavity 8. The cover and the first cavity 8 together form a cavity structure, providing better protection for the main control board and other electronic equipment stored in the first cavity 8; the cover is detachable, which facilitates the maintenance of the main control board and other electronic equipment stored in the first cavity 8, reducing the maintenance cost of the main control board and other electronic equipment.

[0060] Furthermore, one end of the cabinet door 2 is a hinged end, which can be either the end of the cabinet door 2 along its length or the end of the cabinet door 2 along its width. The hinged end is connected to the cabinet body 1 via a hinge 3, meaning that the cabinet door 2 can rotate relative to the cabinet body 1, thereby closing and opening the cabinet door 2. The hinge 3 connection method ensures that the cabinet door 2 and the cabinet body 1 are always connected, preventing the cabinet door 2 from separating from the cabinet body 1 and tipping over. In the open state, the cabinet door 2 is completely outside the first opening 111, avoiding the cabinet door 2 from obstructing or interfering with the first opening 111, thereby creating a larger operating space and making the maintenance and operation of the heat exchange system inside the cabinet body 1 more convenient.

[0061] Furthermore, the other end of cabinet door 2 is a free end, which is opposite to the hinged end of cabinet door 2. The free end is fixed to cabinet body 1 by lock 4, which can play a reliable connection and anti-theft role. Moreover, the unlocking and locking operations are convenient, which further shortens the time for opening and maintaining the cabinet structure and reduces the maintenance cost of thermal management unit.

[0062] Furthermore, the cabinet body 1 is provided with a first frame 112 around the first opening 111. The first frame 112 is configured to protrude along the thickness direction of the cabinet body 1. By providing the first frame 112, the first opening 111 is reinforced to prevent the first opening 111 from being deformed or cracked, which would affect the normal fit between the cabinet door 2 and the first opening 111.

[0063] Furthermore, the edge of the cabinet door 2 is provided with a second frame 21, which is configured to protrude along the thickness direction of the cabinet door 2 to strengthen the cabinet door 2 and prevent the cabinet door 2 from being deformed or cracked, which would prevent the cabinet door 2 from closing the first opening 111 normally.

[0064] Furthermore, the size of the second frame 21 is larger than that of the first frame 112. When the cabinet door 2 closes the first opening 111, the second frame 21 is fitted around the periphery of the first frame 112, thereby acting as a limit between the cabinet door 2 and the cabinet body 1, ensuring that the cabinet door 2 can completely close the first opening 111.

[0065] Furthermore, when the cabinet door 2 is connected to the cabinet body 1 via hinge 3 and lock 4, hinge 3 is located between the second frame 21 and the first frame 112, and lock 4 is located between the second frame 21 and the first frame 112. Concealing hinge 3 between the second frame 21 and the first frame 112 improves the appearance of the cabinet structure; concealing lock 4 between the second frame 21 and the first frame 112 improves the security of lock 4 and prevents it from being damaged by force.

[0066] Furthermore, the cabinet door 2 is provided with air inlets 22 and air outlets 23 spaced apart from each other. External air enters the internal space of the cabinet 1 through the air inlet 22, exchanges heat with the heat exchange system inside the cabinet 1, and is then discharged to the outside atmosphere through the air outlet 23, forming a complete air circulation.

[0067] In one embodiment, the air inlet 22 is located below the air outlet 23. A fan 6 is installed inside the cabinet 1 directly opposite the air inlet 22, and a condenser 7 is installed inside the cabinet 1 directly opposite the air outlet 23. When the fan 6 rotates, airflow enters the cabinet 1 from the outside through the fan 6, passes through various components from the middle of the fan 6, then reaches the second side 12 of the condenser 7, and undergoes sufficient heat exchange through the condenser 7 before being blown out through the air outlet 23 above the cabinet door 2.

[0068] Furthermore, the fan 6 is fixed inside the cabinet 1 by a mounting bracket. The mounting bracket includes a side plate and a top plate. The top plate is close to the first side 11 of the cabinet 1, and the width of the top plate is less than the thickness of the fan 6, so that the top plate and the cabinet 1 form an air duct on the second side 12, ensuring that the airflow can reach the second side 12 of the condenser 7 and improving the effective utilization rate of the airflow.

[0069] Furthermore, at least one of the air inlet 22 and air outlet 23 is equipped with a dust filter 24 to reduce the amount of sand and dust entering the cabinet 1, enabling the heat exchange system to maintain good heat exchange performance for a long time and reducing the frequency of dust cleaning and maintenance. The dust filter 24 is located on the side of the cabinet door 2 facing inwards from the cabinet 1, that is, the dust filter 24 is located in the internal space of the cabinet 1, which can prevent the dust filter 24 from being lost or damaged by human error.

[0070] Furthermore, the dustproof net 24 is detachably connected to the cabinet door 2. For example, the dustproof net 24 is connected to the cabinet door 2 by means of buckles, bolts, etc., so that the dustproof net 24 can be removed for cleaning, thereby improving the cleaning efficiency and cleaning effect.

[0071] like Figure 5 and Figure 6 As shown, the bottom of the cabinet 1 is provided with at least one drainage structure 15, such as a through hole, through groove or channel. The drainage structure 15 is connected to the interior of the cabinet 1, so that the condensate and other liquids generated inside the cabinet 1 can be discharged to the outside of the cabinet 1, preventing excessive water accumulation inside the cabinet structure and damage.

[0072] Furthermore, the bottom of the cabinet 1 forms a first edge on the first side 11, and the drainage structure 15 is positioned close to the first edge. On the one hand, keeping the drainage structure 15 away from the equipment can prevent liquid discharged from the cabinet 1 from leaking into the interior of the equipment and affecting its normal operation; on the other hand, the proximity of the drainage structure 15 to the first opening 111 makes it easier to clean up stains or blockages caused by drainage.

[0073] Specifically, when a drainage structure 15 is provided at the bottom of the cabinet 1, the drainage structure 15 is configured as a through groove extending along the first edge to form a larger drainage area. When at least two drainage structures 15 are provided at the bottom of the cabinet 1, the drainage structures 15 are arranged sequentially along the extension direction of the first edge.

[0074] Furthermore, when the cabinet door 2 closes the first opening 111, at least a portion of the drainage structure 15 is exposed outside the cabinet door 2. That is, the cabinet door 2 does not completely cover the drainage structure 15, or the cabinet door 2 does not cover the drainage structure 15 at all. On the one hand, normal drainage can be achieved when the cabinet door 2 is closed, without the need to specifically open the cabinet door 2 for drainage, thereby effectively preventing water accumulation inside the cabinet 1. On the other hand, when the cabinet door 2 is closed, it is possible to observe whether the drainage structure 15 is blocked or otherwise abnormal, so as to clean or unclog the drainage structure 15 in a timely manner and prevent water accumulation inside the cabinet 1.

[0075] Specifically, the drainage structure 15 can be extended and expanded away from the first edge, so that a portion of the drainage structure 15 is away from the cabinet door 2, thereby being exposed to the outside of the cabinet door 2. Alternatively, the entire drainage structure 15 can be translated away from the first edge, so that the entire drainage structure 15 is away from the cabinet door 2, thereby being completely exposed to the outside of the cabinet door 2.

[0076] like Figure 5 and Figure 7 As shown, the cabinet structure further includes a dehumidification module 5, which is installed inside the cabinet 1. The dehumidification module 5 reduces water vapor inside the cabinet 1, keeping the cabinet 1 in a dry environment. The bottom of the dehumidification module 5 is provided with a drain outlet 51. The condensate generated by the dehumidification module 5 flows from the drain outlet 51 into the cabinet 1, and is then discharged through the drainage structure 15 of the cabinet 1.

[0077] Specifically, the installation position of the dehumidification module 5 inside the cabinet 1 can be reasonably set according to needs. For example, the dehumidification module 5 can be installed on the surface of the second side 12 of the cabinet 1, or the dehumidification module 5 can be installed on the wall 13 of the cabinet 1. The dehumidification module 5 includes a shell structure, and the drain outlet 51 is located at the lower part of the shell. The shell structure is equipped with a dehumidification evaporator, a dehumidification capillary tube and a dehumidification fan. The dehumidification evaporator is located below the dehumidification fan.

[0078] Furthermore, the heat exchange system includes an evaporator, condenser 7, compressor, expansion valve, plate heat exchanger, water pump, inlet, and outlet, etc., to achieve functions such as cooling or heating. The cabinet structure can also be equipped with a dry cooler, which is stacked side by side with the condenser 7 and shares a fan 6.

[0079] Among them, the electromagnetic expansion valve, plate heat exchanger, electric heater, water pump, pressure sensor and temperature sensor can be set as an integrated module to reduce complex pipeline connections. That is to say, the components of the integrated module can be assembled outside the cabinet 1, and then the integrated module is directly installed inside the cabinet 1. Then, it is connected to other modules by quick-connect pipelines, which reduces the assembly time of the whole machine, improves production efficiency, reduces the air resistance inside the cabinet, reduces the risk of pipeline leakage, and improves the reliability of the heat exchange system.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
