Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, and in particular to a liquid cooling device and a containerized converter system. Background Technology

[0002] A containerized converter is a modular power conversion device that integrates a converter and related supporting equipment (such as transformers or control systems) into a standard container. It is one of the core components of a containerized energy storage system, responsible for achieving efficient bidirectional conversion between DC and AC power, and supporting the charging and discharging control and grid interaction functions of the energy storage system.

[0003] In related technologies, containerized converters typically employ a split liquid cooling system, where the liquid cooling components are installed inside the container, while the water-air heat exchange components are installed outside. To prevent the separately installed water-air heat exchange components from interfering with the location of other equipment, they are generally placed at a distance from the containerized converter. This necessitates the use of underground trenches or overhead pipelines to transport coolant to the location of the water-air heat exchange components for cooling, resulting in higher installation costs.

[0016] A control component, which is electrically connected to both the liquid cooling component and the first fan; and

[0017] The second cabinet houses the control components. The second cabinet is disposed within the housing and is arranged in the second horizontal direction with the first cabinet. The opening direction of the second cabinet is opposite to that of the first cabinet.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0044] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0045] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In a first aspect, embodiments of this application provide a liquid cooling device 1 for liquid cooling heat dissipation of a containerized converter 3. The liquid cooling device 1 includes a housing 11, a liquid cooling assembly 12, a pipe connection assembly 13, and a water-air heat exchange assembly 14. The housing 11 is used to install on the containerized converter 3 in a first horizontal direction (e.g., ...). Figure 1 On one side (as shown in the X direction), the housing 11 has a first sidewall facing the container. A liquid cooling assembly 12 is disposed within the housing 11. A pipe connection assembly 13 is mounted on the first sidewall, with one end penetrating the first sidewall to communicate with the liquid cooling assembly 12, and the other end used to connect with the pipe port of the containerized converter 3. This allows coolant to circulate within the liquid cooling assembly 12, the pipe connection assembly 13, and the pipes of the containerized converter 3 for liquid cooling heat dissipation of the converter. A water-air heat exchange assembly 14 is disposed on the housing 11 and is used to dissipate heat from the liquid cooling assembly 12.

[0046] The pipe connection assembly 13 and the containerized converter 3 are respectively equipped with a first clamp interface and a second clamp interface. The first clamp interface and the second clamp interface can be quickly disassembled and assembled, which can realize the quick disassembly and assembly of the pipe connection assembly 13 and the containerized converter 3, shortening the installation or disassembly time of the liquid cooling device 1 and the containerized converter 3, thereby improving the efficiency of maintenance or replacement of the liquid cooling device 1. For example, when the liquid cooling component 12 or the water-air heat exchange component 14 in the liquid cooling device 1 needs maintenance or replacement, it can be quickly disassembled from the containerized converter 3 through the pipe connection assembly 13 to separate the liquid cooling device 1 and the containerized converter 3, so as to facilitate the maintenance or replacement of the liquid cooling device 1; after the liquid cooling device 1 is maintained or replaced, it can be quickly reconnected from the containerized converter 3 through the pipe connection assembly 13 to install the liquid cooling device 1 and the containerized converter 3.

[0047] In this embodiment, the water-air heat exchange component 14 and the liquid cooling component 12 are integrated to form a liquid cooling device 1, which can shorten the distance between the water-air heat exchange component 14 and the liquid cooling component 12. Compared with the prior art of integrating the liquid cooling component 12 into the containerized converter 3, the container size of the containerized converter 3 can be reduced. At the same time, by installing the liquid cooling device 1 on one side of the containerized converter 3 through the pipe docking component 13, the distance of coolant circulation can be shortened and the flow resistance can be reduced. Compared with the prior art, which does not require the use of trenches or overhead pipelines to transport coolant, the cooling performance can be improved, and on-site pipe laying is not required, thus reducing installation costs.

[0048] The liquid cooling component 12 may include devices such as a water pump, a filter, and an expansion tank. Since the liquid cooling component 12 is existing technology, it will not be described in detail here.

[0049] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the water-air heat exchange assembly 14 includes a first fan 141, which is disposed on the top of the housing 11.

[0050] The first fan 141 is disposed on the top of the housing 11 and can dissipate heat from the inside of the housing 11. For example, after the coolant achieves liquid cooling of the containerized converter 3, the coolant temperature rises. The coolant flows through the pipes, pipe docking assembly 13 and liquid cooling assembly 12 of the containerized converter 3 in sequence. When it flows to the liquid cooling assembly 12, the first fan 141 dissipates heat from the inside of the housing 11 and dissipates heat from the coolant, thereby lowering the coolant temperature and realizing heat exchange of the coolant.

[0051] In some embodiments, the number of first fans 141 can be four. Of course, the number of first fans 141 can also be less than four or more than four, which is not limited here.

[0052] Please continue reading. Figure 2 and Figure 3 In some embodiments, the water-air heat exchange assembly 14 further includes a finned radiator 142, which is disposed inside the housing 11 and adjacent to the first fan 141.

[0053] The finned heat sink 142 is disposed between the first fan 141 and the liquid cooling assembly 12. When the coolant flows through the liquid cooling assembly 12 after the temperature rises, the finned heat sink 142 can improve the heat exchange efficiency of the coolant and, together with the first fan 141, can shorten the cooling time of the coolant.

[0054] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, the liquid cooling device 1 further includes a first cabinet 16 for accommodating the liquid cooling assembly 12. The first cabinet 16 is disposed within the housing 11, and the opening direction of the first cabinet 16 is parallel to a second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0055] A first cabinet 16 is set inside the housing 11, and the liquid cooling component 12 is set inside the first cabinet 16, which can further improve the waterproof capability of the liquid cooling component 12.

[0056] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, the first cabinet 16 is fitted to the first side wall.

[0057] The first cabinet 16 fits against the first side wall, which can reduce the distance between the first cabinet 16 and the first side wall, thereby reducing the distance between the pipe docking assembly 13 and the liquid cooling assembly 12, and thus shortening the length of the pipe used to connect the pipe docking assembly 13 and the liquid cooling assembly 12.

[0058] In some embodiments, the top plate of the first cabinet 16 is provided with a through first ventilation opening (not shown in the figure), and the first ventilation opening is provided with a second fan (not shown in the figure).

[0059] Understandably, the first fan 141 is located at the top of the housing 11, which can form a vertical heat dissipation air duct inside the housing 11. A through-hole first vent is provided on the top plate of the first cabinet 16, so that a vertical heat dissipation air duct is also formed inside the first cabinet 16. At the same time, it can reduce the distance that hot air inside the first cabinet 16 needs to flow from the first vent to the first fan 141, thereby improving the heat dissipation efficiency of the liquid cooling component 12.

[0060] In addition, the second fan installed at the first vent can further increase the rate at which hot air flows out of the first vent from the first cabinet 16, thereby further improving the heat dissipation efficiency of the liquid cooling component 12.

[0061] Please refer to the following: Figure 2 , Figure 5 and Figure 6 In some embodiments, the liquid cooling device 1 further includes a control component 15 and a second cabinet 17. The control component 15 is electrically connected to the liquid cooling component 12 and the first fan 141. The second cabinet 17 houses the control component 15 and is disposed within the housing 11. The second cabinet 17 and the first cabinet 16 are arranged in a second horizontal direction, and the opening direction of the second cabinet 17 is opposite to that of the first cabinet 16.

[0062] The control component 15 can control the start and stop of the liquid cooling component 12 and the speed of the first fan 141. The control component 15 may include devices such as a PLC, circuit breaker, and relays. Since the control component 15 is prior art, it will not be described in detail here.

[0063] A second cabinet 17 is provided inside the housing 11, and the control component 15 is housed within the second cabinet 17, which can further enhance the waterproof capability of the control component 15. In addition, the control device and the liquid cooling component 12 are respectively housed in independent cabinets within the housing 11 via the second cabinet 17 and the first cabinet 16, with clear functional division.

[0064] In some embodiments, the top plate of the second cabinet 17 has a through second ventilation opening (not shown in the figure), and the second ventilation opening is equipped with a third fan (not shown in the figure).

[0065] A through-hole second ventilation opening is provided on the top plate of the second cabinet 17, so that a vertical heat dissipation air duct is also formed inside the second cabinet 17. At the same time, the distance that hot air inside the second cabinet 17 needs to flow from the second ventilation opening to the first fan 141 can be reduced, thereby improving the heat dissipation efficiency of the control component 15.

[0066] In addition, the third fan installed at the second vent can further increase the rate at which hot air flows out of the second cabinet 17 through the second vent, and further improve the heat dissipation efficiency of the control component 15.

[0067] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the housing 11 further has opposing second and third sidewalls, both of which are connected to the first sidewall, and both the second and third sidewalls are provided with a plurality of square holes 111. By providing a plurality of square holes 111 in the second and third sidewalls, the airflow resistance can be reduced and the heat dissipation efficiency can be improved.

[0068] Please refer to it again. Figure 1 Secondly, this application embodiment also provides a containerized converter system 2, including a base 21, a containerized converter 3 and the aforementioned liquid cooling device 1, wherein the containerized converter 3 and the liquid cooling device 1 are both mounted on the base 21.

[0069] By placing both the containerized converter 3 and the liquid cooling device 1 on the base 21, the positional relationship between the liquid cooling device 1 and the containerized converter 3 can be further determined.

[0070] For example, the base 21 may be 8m long in the first horizontal direction, the container of the containerized converter 3 may be 5.4m long in the first horizontal direction, and the housing 11 of the liquid cooling device 1 may be 2.5m long in the first horizontal direction.

[0071] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
