[0034] like Figure 1 , Figure 2 and Figure 3 As shown, some embodiments of this utility model disclose a charging terminal cabinet 1, including a shell 11, a partition 12, a first sealing member 13, and a second sealing member 14, as detailed below:
[0035] At least two sides of the partition 12 are sealed to the inner wall of the housing 11. Understandably, the at least two sides can be two sides, three sides, or any number of sides, depending on the shape of the partition 12. The partition 12 divides the interior of the housing 11 into a first cavity 111 for accommodating an electronic module (not shown) and a second cavity 112 for accommodating a cooling module 2. The first cavity 111 and the second cavity 112 are distributed in the height direction H of the housing 11, and the second cavity 112 is located below the first cavity 111.
[0036] The outer shell 11 on both sides of the second cavity 112 is provided with a heat dissipation structure. The partition 12 is provided with a pipeline through hole 121, and the first sealing element 13 is provided on the pipeline through hole 121.
[0037] For ease of maintenance, the housing 11 has at least one door 113. Understandably, at least one door can be one, two, three, or any number of doors. A partition 12 corresponds to the door 113 of the housing 11, and a second seal 14 is provided on the side of the partition 12 opposite to the door 113 of the housing 11. When the door 113 of the housing 11 is closed, the second seal 14 abuts against the door 113 of the housing 11.
[0038] The heat dissipation structure of the charging terminal cabinet 1 in this embodiment can accelerate the airflow in the second cavity 112, which facilitates the coordination of heat dissipation in the second cavity 112 and improves heat dissipation efficiency. In addition, the partition 12, the first sealing member 13 and the second sealing member 14 can form a completely sealed first cavity 111, which effectively prevents the water vapor generated by heat in the lower second cavity 112 from rising into the first cavity 111.
[0039] In some embodiments, the outer casing 11 is a metal casing, such as iron or aluminum. Iron and aluminum are just examples and are not intended to limit this application. Other metals may also be used.
[0040] In some embodiments, such as Figure 1 As shown, the partition 12 is arranged horizontally, that is, perpendicular to the height direction H of the outer shell 11. The partition 12 divides the interior of the outer shell 11 into two rectangular cavities. Furthermore, for easy disassembly, the partition 12 is installed inside the outer shell 11 via a detachable connection, such as a nut lock. Additionally, the partition 12 is a waterproof plate, such as a stainless steel plate or a PVC plate. The use of nuts, stainless steel plates, and PVC plates here are merely examples and are not intended to limit this application; other materials may also be used.
[0041] In some embodiments, such as Figure 1 As shown, the first sealing element 13 is a sealing elastic ring, which is embedded in the pipeline through-hole 121. When a pipeline passes through the sealing elastic ring, the elasticity of the sealing elastic ring is used to achieve a seal between the sealing elastic ring and the outer wall of the pipeline. For example, the sealing elastic ring is a silicone ring. The embedding and silicone ring mentioned here are only examples and are not intended to limit this application. Other types are also possible.
[0042] In some embodiments, such as Figure 1 As shown, the second sealing element 14 is a sealing elastic strip, which is adhered to the partition 12. When the door 113 of the outer casing 11 is closed, the second sealing element 14 abuts against the door 113 of the outer casing 11 to compress the sealing elastic strip, thereby achieving a seal between the sealing elastic strip and the door 113 of the outer casing 11 using the elasticity of the sealing elastic strip. For example, the sealing elastic strip can be a sealing silicone strip. The adhesion and sealing silicone strip mentioned here are merely examples and are not intended to limit this application; other types are also possible.
[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the door 113 of the outer casing 11 can be a single door 113 or a double door 113, and the door 113 of the outer casing 11 can cover the first cavity 111 and / or the second cavity 112, or cover the first cavity 111 and part of the second cavity 112, or cover the second cavity 112 and part of the first cavity 111.
[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the charging terminal cabinet 1 also includes a fixing seat 15 for fixing one end of the charging gun's charging cable. The fixing seat 15 is disposed on the outer shell 11 corresponding to the first cavity 111. The fixing seat 15 is recessed and has an opening for one end of the charging gun's charging cable to pass through, so as to electrically connect with the electronic module inside the first cavity 111. The fixing seat 15 also fixes one end of the charging cable, such as by locking it with a clip. The recessed shape and the clip locking are only examples and are not intended to limit this application. Other methods are also possible.
[0045] In some embodiments, such asFigure 1 and Figure 2 As shown, the charging terminal cabinet 1 also includes a cable holder 16 for suspending the charging cable, which is disposed on the outer casing 11. For example, the cable holder 16 is an "L"-shaped hook structure. The "L"-shaped hook structure here is only an example and is not intended to limit this application; other types are also possible.
[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the charging terminal cabinet 1 also includes a mounting base 17 for installing an emergency stop button. The mounting base 17 is disposed on the outer shell 11 corresponding to the first cavity 111, and the emergency stop button is electrically connected to the electronic module inside the first cavity 111. For example, the mounting base 17 is a groove structure. The groove structure here is only an example and is not intended to limit this application; other structures are also possible.
[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting bracket 15, the winding bracket 16, and the mounting base 17 are located on the same side of the housing 11, allowing the user to conveniently store the charging cable during charging and to easily press the emergency stop button in case of an emergency. Furthermore, the mounting bracket 15, the winding bracket 16, and the mounting base 17 are fixedly connected to the housing 11, such as by welding, to avoid the possibility of human-caused damage.
[0048] In some embodiments, such as Figure 1 As shown, the charging terminal cabinet 1 also includes a support base 18 for supporting the cooling module 2, which is located at the inner bottom of the second cavity 112. For example, the support base 18 is a support platform, which is installed at the inner bottom of the second cavity 112 by means of a detachable connection, such as a nut lock, which allows for quick and convenient disassembly of the cooling module 2 for maintenance, solving the problem of difficult maintenance after the cooling module 2 is installed. The support platform and nut lock here are just examples and are not intended to limit this application; other types are also possible.
[0049] In some embodiments, the charging terminal cabinet 1 also includes a water collection tray (not shown) for collecting condensate. The water collection tray is located at the bottom of the second cavity 112, the support base 18 is located on the water collection tray, and a drain outlet is provided at the outer shell 11 corresponding to the water collection tray. When water vapor condenses, the water will be collected on the water collection tray and can be discharged through the drain outlet.
[0050] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the heat dissipation structure includes an air inlet 114 and an air outlet 115. For example, the air inlet 114 is located on the door 113 of the outer casing 11, and the air outlet 115 is located on the side of the outer casing 11 opposite to the door 113. An air duct is formed between the air inlet 114 and the air outlet 115 in the second cavity 112, which can accelerate the air circulation, allowing the air to flow out faster, resulting in higher heat dissipation efficiency and faster cooling.
[0051] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to provide good ventilation and heat dissipation, and to effectively protect the modules inside the cabinet under various weather conditions, the charging terminal cabinet 1 also includes louvers 19. The louvers 19 are respectively located at the air inlet 114 and the air outlet 115. Specifically, they are installed at the air inlet 114 and the air outlet 115 in a detachable connection manner, such as by locking with nuts, for easy disassembly.
[0052] In some embodiments, such as Figure 4 As shown, the venetian blind 19 includes multiple blades 191 and supports 192 located on both sides of the blades 191. Understandably, the multiple blades 191 can be two, three, or other quantities. The multiple blades 191 are arranged sequentially along the height direction of the supports 192, and the multiple blades 191 all face the same direction.
[0053] Some embodiments of this utility model disclose a charging terminal, specifically a split-type ultra-fast charging terminal. The charging terminal includes the charging terminal cabinet 1, cooling module 2, and electronic module (not shown) as described in any of the above embodiments. The electronic module is disposed in the first cavity 111, and the cooling module 2 is disposed in the second cavity 112.
[0054] It should be noted that the electronic module includes a variety of mature components found in existing charging terminals, which will not be elaborated upon here.
[0055] In some embodiments, the charging terminal also includes a charging gun, and the cooling pipes of the cooling module 2 pass through the first seal 13 and are built into the gun wires of the charging gun to achieve heat exchange.
[0056] Cooling module 2 is used to dissipate heat from the gun wire, such as... Figure 1As shown, it includes a liquid cooling pump 21, a coolant reservoir 22 for storing coolant, and a radiator 23. The inlet end of the liquid cooling pump 21 is connected to the outlet end of the reservoir 22, and the outlet end of the liquid cooling pump 21 is connected to the inlet end of the radiator 23 via a cooling pipe. The outlet end of the radiator 23 is connected to the inlet end of the reservoir 22. The specific working process is as follows: the liquid cooling pump 21 draws coolant from the reservoir 22, driving the coolant to flow. The coolant absorbs heat generated by the cable in the gun wire through the cooling pipe built into the gun wire, and then flows to the radiator 23, where it releases heat to the external environment. The cooled liquid then returns to the reservoir 22, and the cycle begins again. For example, the radiator 23 is a finned radiator 23. The finned radiator 23 used here is merely an example and is not intended to limit this application; other types are also possible.
[0057] When the cooling module 2 is operating, the liquid cooling pump 21 generates heat, and the heat exchanger 23 also generates heat and water vapor. Therefore, heat and water vapor accumulate in the second cavity 112. The liquid cooling pump 21 has its own fan for heat dissipation, which, together with the air inlet 114 and air outlet 115, can further accelerate the airflow in the second cavity 112, facilitating coordinated heat dissipation within the second cavity 112 and improving heat dissipation efficiency. In addition, the partition 12, the first seal 13, and the second seal 14 can form a completely sealed first cavity 111, effectively preventing water vapor in the lower second cavity 112 from rising into the first cavity 111, thus protecting the electronic modules in the upper first cavity 111.
[0058] It is understood that the above embodiments only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this utility model, and can also make several modifications and improvements, all of which fall within the protection scope of this utility model. That is, the embodiments described "in some embodiments" can be freely combined with any of the preceding and following embodiments. Therefore, all equivalent transformations and modifications made within the scope of the claims of this utility model should fall within the coverage of the claims of this utility model.
