[0049] Based on considerations of the background technology, the embodiments of the present application provide a liquid cooling device, an energy storage container and a locomotive. When the liquid cooling device is applied to the energy storage container, it can improve the heat dissipation capacity per unit space of the energy storage container. Under the same heat dissipation requirements, it can reduce the space occupied by the liquid cooling unit, thereby improving the space utilization of the energy storage container.

[0050] Next, the liquid cooling device in the embodiment of the present application is first introduced in detail.

[0051] According to some embodiments of this application, please refer to Figure 1 and Figure 2The liquid cooling device 100 provided in the embodiment of the present application includes a liquid cooling unit 30 and two independent air chambers Q. The two air chambers Q are arranged adjacent to each other in the length direction of the liquid cooling device 100 and are open in reverse. A liquid cooling unit 30 is arranged in each air chamber Q, and each liquid cooling unit 30 separates the air chamber Q into an air inlet duct J and an air outlet duct C. The air inlet duct J and the air outlet duct C are connected to the opening end q of the corresponding air chamber Q. The liquid cooling unit 30 includes a heat dissipation fan 31, and the heat dissipation fan 31 is used to promote airflow from the air inlet duct J to the air outlet duct C through the liquid cooling unit 30.

[0052] The two air cavities Q are arranged adjacent to each other in the length direction of the liquid cooling device 100 and open toward different sides in the length direction of the liquid cooling device 100, so that the two air cavities Q have opening ends q arranged opposite to each other in the length direction of the liquid cooling device 100. In actual application, the length direction of the liquid cooling device 100 corresponds to the horizontal direction.

[0053] The liquid cooling device 100 is equipped with two groups of liquid cooling units 30, and a liquid cooling unit 30 is arranged in each air cavity Q. The liquid cooling unit 30 uses circulating coolant to remove excess heat from the battery system or to moderately heat the battery system so that the battery system reaches the required operating temperature. In actual application, the liquid cooling unit 30 can be selected from a smaller liquid cooling unit 30 model in the art according to actual needs, and its specific structure is not limited here.

[0054] The liquid cooling unit 30 divides the internal space of the air cavity Q into an air inlet J and an air outlet C. The air inlet of the air inlet J and the air outlet of the air outlet C are both located at the opening end q of the corresponding air cavity Q. It can be understood that the air inlet J is located on the air inlet side of the liquid cooling unit 30, and the air outlet C is located on the air outlet side of the liquid cooling unit 30. The liquid cooling unit 30 is equipped with a cooling fan 31. When the cooling fan 31 is started, the external airflow enters the air inlet J from the opening end q of the air cavity Q, and then flows through the liquid cooling unit 30 to take away the internal heat of the liquid cooling unit 30, and finally is discharged from the air cavity Q through the air outlet C and the opening end q of the air cavity Q.

[0055] When the above-mentioned liquid cooling device 100 is applied to the energy storage container 1000, the length direction of the liquid cooling device 100 corresponds to the width direction of the box body 200 of the energy storage container 1000, that is, the liquid cooling device 100 has two groups of liquid cooling units 30 that independently inlet and outlet air on different sides in the width direction of the energy storage container 1000, so that a larger number of liquid cooling units 30 can be arranged in the unit volume of the energy storage container 1000. Under the condition of the same heat dissipation demand, the space occupied by the liquid cooling unit 30 can be reduced, thereby improving the space utilization rate of the energy storage container 1000.

[0056] In some embodiments, the liquid cooling device 100 includes a supporting member 10 and a wind cover 20 . The wind cover 20 is disposed on the supporting member 10 and forms two wind cavities Q.

[0057] The supporting member 10 is used to carry the liquid cooling unit 30, and the liquid cooling device 100 is installed on the energy storage container 1000 via the supporting member 10. The supporting member 10 can be a supporting plate, a supporting rod, a supporting frame 11, etc., and the specific structural form is not limited. The wind cover 20 is arranged on the supporting member 10 and forms two wind cavities Q. The wind cover 20 can form each wind cavity Q independently, or it can form each wind cavity Q together with the supporting member 10.

[0058] At this time, the liquid cooling unit 30 is reliably supported, and the installation of the liquid cooling device 100 on the energy storage container 1000 is achieved through the supporting member 10, and the installation of the liquid cooling device 100 is convenient.

[0059] In some embodiments, please refer to Figure 2 The wind shield 20 includes a first wind shield 21 and a second wind shield 22 arranged in sequence in the length direction thereof, both of which are open at one end facing the supporting member 10, and the openings are opposite to each other in the length direction. The first wind shield 21 is connected to the supporting member 10 to form a first wind cavity Q1, and the second wind shield 22 is connected to the supporting member 10 to form a second wind cavity Q2.

[0060] At this time, the first wind cover 21 and the second wind cover 22 are two independent wind covers 20, together with the supporting member 10, to form an independent first wind cavity Q1 and a second wind cavity Q2, that is, the supporting member 10 is used to form the cavity wall of the wind cavity Q, which can reduce the consumables of the wind cover 20 and reduce the cost. Moreover, the liquid cooling unit 30 can be directly installed on the supporting member 10, and the liquid cooling unit 30 is more reliably supported.

[0061] Specifically, the first wind shield 21 and the second wind shield 22 may be in a rectangular parallelepiped shape, and both sides thereof are open, one side faces the supporting member 10, and the other side serves as an open end q. The first wind shield 21 and the second wind shield 22 may be spaced apart by an appropriate distance in the length direction of the liquid cooling device 100 to reduce the temperature influence between the two wind chambers Q.

[0062] In the embodiment of the present application, the formation of the two wind cavities Q is not limited to the above scheme. In other embodiments, the first wind shield 21 and the second wind shield 22 can also be integrated into an integral wind shield, and the integral wind shield and the supporting member 10 together form an independent first wind cavity Q1 and a second wind cavity Q2. Alternatively, the first wind shield 21 and the second wind shield 22 only have an open end q, and each independently forms a first wind cavity Q1 and a second wind cavity Q2.

[0063] In some embodiments, please refer to Figure 2 The supporting member 10 includes a frame 11 and a sealing plate 12. The sealing plate 12 is arranged on the frame 11. The wind cover 20 is arranged on the sealing plate 12 and forms a wind cavity Q together with the sealing plate 12.

[0064] The frame 11 generally includes a plurality of intersecting beams, which mainly bear the load. The wind shield 20 may be fixed on the frame 11. Openings are formed between the beams in the frame 11. The sealing plate 12 covers the openings of the frame 11 to form an air cavity Q with an open end q together with the wind shield 20 to prevent air leakage at the bottom of the air cavity Q. The liquid cooling unit 30 located in the air cavity Q may be fixedly connected to the beams of the frame 11.

[0065] At this time, the supporting member 10 is composed of a closing plate 12 and a frame 11. The frame 11 can improve the supporting capacity of the supporting member 10, and the closing plate 12 mainly has a sealing effect. Under the same bearing capacity, the supporting member 10 consumes less material.

[0066] In some embodiments, please refer to Figure 2 The liquid cooling unit 30 includes a fixing portion 32 fixedly connected to the supporting member 10, and a heat dissipation fan 31 is protruded on the air inlet side and / or the air outlet side of the liquid cooling unit 30, and the fixing portion 32 and the heat dissipation fan 31 are located on the same side of the liquid cooling unit 30.

[0067] The fixing portion 32 can be connected to the supporting member 10 by fasteners such as screws, rivets, or snaps. The air inlet side of the liquid cooling unit 30 refers to the side that defines the air inlet duct J with the inner wall of the air cavity Q, and the air outlet side of the liquid cooling unit 30 refers to the side that defines the air outlet duct C with the inner wall of the air cavity Q. The airflow flows from the air inlet side of the liquid cooling unit 30 to its air outlet side. Ventilation ports are provided on the air outlet side and the air inlet side of the liquid cooling unit 30, and the heat dissipation fan 31 can be provided at the vents on the air outlet side and / or the vents on the air inlet side.

[0068] The cooling fan 31 is protruding, that is, at least part of the cooling fan 31 is located in the air inlet J or the air outlet C. Since the fixing part 32 and the cooling fan 31 are arranged on the same side of the liquid cooling unit 30, the protruding cooling fan 31 may hinder the connection of the fixing part 32, making it inconvenient to operate. In actual application, the liquid cooling unit 30 can be first installed on the supporting member 10, and then the supporting member 10 can be installed at the energy storage container 1000, so that the liquid cooling device 100 is more convenient to install.

[0069] In some embodiments, the distance between the air inlet side and the cavity wall of the air cavity Q (i.e., the width of the air inlet duct J) is greater than 150 mm, and the distance between the air outlet side and the cavity wall of the air cavity Q (i.e., the width of the air outlet duct C) is greater than 150 mm. In this way, the widths of the air inlet duct J and the air outlet duct C are larger, the air cavity Q has a larger exchange rate, and the heat dissipation effect of the liquid cooling unit 30 is better.

[0070] In some embodiments, please refer to Figure 2 , and combined with Figure 4A notch 33 is formed on the air inlet side of the liquid cooling unit 30 facing the opening end q, and the notch 33 is connected to the corresponding air inlet duct J. The liquid cooling device 100 further includes a wind shield 40 , which is disposed at the opening end q and blocks the notch 33 .

[0071] For some models of liquid cooling units 30, a notch 33 facing the open end q is formed at one end of the air inlet side, and the notch 33 is connected to the air inlet duct J. A windshield 40 is provided corresponding to the notch 33, and the windshield 40 is fixed on the wind cover 20. The windshield 40 can block the notch 33 to prevent the airflow entering the air inlet duct J from leaking out from the notch 33.

[0072] In some embodiments, please refer to Figure 1 The liquid cooling device 100 includes a first liquid cooling unit 30A and a second liquid cooling unit 30B, which are located in different air chambers Q, and the heat dissipation fans 31 of the two are located on the air inlet side or the air outlet side of the two. The heat dissipation fans 31 of the two are located on different sides of the liquid cooling device 100 in the width direction.

[0073] The width direction of the liquid cooling device 100 is substantially perpendicular to its length direction. In practical applications, the width direction of the liquid cooling device 100 is horizontal. The air inlet duct J and the air outlet duct C are located on different sides of the liquid cooling unit 30 in the width direction.

[0074] The first liquid cooling unit 30A is located in the first air cavity Q1, and the second liquid cooling unit 30B is located in the second air cavity Q2. The heat dissipation devices of both are arranged on the air inlet side or the air outlet side. Moreover, the heat dissipation devices of both are located on different sides of the liquid cooling device 100 in the width direction.

[0075] At this time, the first liquid cooling unit 30A and the second liquid cooling unit 30B are units of the same model, and due to different placement positions, the heat dissipation devices of the two are on different sides in the width direction of the liquid cooling device 100. In this way, only one type of liquid cooling unit 30 needs to be configured, and when the staff installs, there is no need to identify the unit type, and the installation is faster.

[0076] In one embodiment of the present application, please refer to Figure 1 and Figure 2 The liquid cooling device 100 includes a first wind hood 21, a second wind hood 22, a supporting member 10, two liquid cooling units 30 and a baffle. The first wind hood 21 and the second wind hood 22 are sequentially arranged on the supporting member 10 in the length direction of the liquid cooling device 100, and together with the supporting member 10 form two wind cavities Q that are open back to back in the length direction. The liquid cooling unit 30 is supported on the supporting member 10, and a liquid cooling unit 30 is arranged in each wind cavity Q. A notch 33 is formed at the air inlet group of the liquid cooling unit 30 corresponding to the opening end q, and a wind shield 40 is arranged at the position of the opening end q of the wind hood 20 corresponding to the notch 33.

[0077] In addition, the present application embodiment also provides an energy storage container 1000, please refer to Figure 3 , including a box 200, a battery cluster and the liquid cooling device 100 in the above embodiment, the battery cluster and the liquid cooling device 100 are arranged in the box 200. Among them, the liquid cooling device 100 is provided with at least one group in the height direction of the box 200, and the box 200 is provided with an air inlet window 211 and an air outlet window 212, the air inlet window 211 is arranged directly opposite to the air inlet of the liquid cooling device 100, and the air outlet window 212 is arranged directly opposite to the air outlet of the liquid cooling device 100.

[0078] The battery cluster is a battery system that stores and supplies electric energy in the energy storage container 1000. Its specific structure is not described here in detail. Please refer to the common knowledge in the field. The liquid cooling device 100 provides coolant to the battery cluster through the liquid cooling pipeline. The coolant can flow through the cooling structure such as the liquid cooling plate in the battery cluster to achieve the regulation of the working temperature of the battery cluster.

[0079] Generally, the box 200 is in the shape of a rectangular parallelepiped, and the length direction of the liquid cooling device 100 is the same as the width direction of the box 200. The liquid cooling device 100 is installed on the load-bearing structure in the box 200 through its supporting member 10. Figure 3 The load-bearing structure includes columns 215 and beams 214 . A plurality of columns 215 are spaced apart in the length direction of the box body 200 to form an installation space S. The beams 214 are located in the installation space S and supported on the columns 215 . The supporting member 10 is installed on the beams 214 .

[0080] The liquid cooling device 100 may be arranged in at least one group, for example, two groups or three groups, in the height direction of the box 200, depending on the required heat dissipation requirements. Specifically, the liquid cooling device 100 may be arranged near the top or bottom of the box 200, so as to utilize the remaining space of the installation space S where the liquid cooling device 100 is located. Figure 3 In the illustrated embodiment, the liquid cooling device 100 is arranged on the top of the box 200 , and the bottom space thereof can be used to install other structures such as a high-voltage box, thereby improving the space utilization of the box 200 .

[0081] The box 200 is provided with an air inlet window 211 and an air outlet window 212, which can be in the form of, but not limited to, louvers. It is understandable that the air inlet window 211 and the air outlet window 212 are provided on both sides of the box 200 in the width direction, so as to be able to independently correspond to the air inlet duct J and the air outlet duct C in the two air cavities Q of the liquid cooling device 100.

[0082] In actual application, the air flow outside the box 200 enters the air inlet J of the air cavity Q through the air inlet window 211, and then flows through the liquid cooling unit 30 in the air cavity Q to exchange heat with the liquid cooling unit 30. The air flow after heat exchange is discharged outside the box 200 through the air outlet C of the air cavity Q and the air outlet window 212. In this way, the air flow outside the box 200 can be continuously circulated to dissipate heat from the liquid cooling unit 30.

[0083] The energy storage container 1000 uses the airflow outside the box 200 to dissipate heat from the liquid cooling unit 30, which is not only economical, but also in the dynamic operation environment of the locomotive, the airflow outside the box 200 is fast, the heat exchange efficiency with the liquid cooling unit 30 is high, and the liquid cooling unit 30 has a good heat dissipation effect, so that the liquid cooling unit 30 can efficiently exchange heat between battery clusters, and the energy storage container 1000 has a good heat dissipation effect and high reliability. Moreover, a large number of liquid cooling units 30 can be arranged within the unit volume of the energy storage container 1000. Under the same heat dissipation requirements, the space occupied by the liquid cooling unit 30 can be reduced, thereby improving the space utilization rate of the energy storage container 1000.

[0084] It should be noted that when multiple groups of liquid cooling devices 100 are arranged in the energy storage container 1000, an air outlet window 212 may be arranged on the same side of the box body 200 to correspond to the air outlet ducts C of all the liquid cooling devices 100, and an air inlet window 211 may be arranged on the same side of the box body 200 to correspond to the air inlet ducts J of all the liquid cooling devices 100. Of course, an air inlet window 211 and an air outlet window 212 may be arranged on the box body 200 to correspond to the air inlet ducts J and the air outlet ducts C of each liquid cooling device 100.

[0085] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 5 The box body 200 includes a heat dissipation box door 210 , and an air inlet window 211 and an air outlet window 212 are located on the heat dissipation box door 210 .

[0086] The heat dissipation box door 210 is used to open the installation space S where the liquid cooling device 100 is located in the box body 200, and the air inlet window 211 and the air outlet window 212 are arranged on the heat dissipation box door 210. At this time, the heat dissipation box door 210 is arranged so that the heat dissipation box door 210 can be opened when the liquid cooling device 100 is installed, which facilitates the installation of the liquid cooling device 100.

[0087] In some embodiments, a fan is provided at the air inlet window 211 and / or the air outlet window 212. In the locomotive running environment, when the airflow passes through the air inlet window 211 and the air outlet window 212, the air pressure outside the box 200 is likely to be greater than the air pressure inside the air cavity Q, making the airflow in and out of the air cavity Q unsmooth. The fan is provided at the air inlet window 211 and / or the air outlet window 212 to speed up the airflow inside and outside the air cavity Q and improve the heat dissipation effect.

[0088] In some embodiments, please refer to Figure 4 and Figure 5 An air guide cover 213 is protruding from the inner side of the heat dissipation box door 210, and an air guide cover 213 is provided between the air inlet window 211 and the air inlet duct J and / or between the air outlet window 212 and the air outlet duct C.

[0089] An air guide hood 213 is provided on the inner side of the air inlet window 211 and the inner side of the air outlet window 212, and the air inlet window 211 is connected to the air inlet duct J through the air guide hood 213, and the air outlet window 212 is connected to the air outlet through the air guide hood 213, so as to reduce the cross-flow of cold and hot air in the gap between the heat dissipation box door 210 and the liquid cooling device 100.

[0090] Specifically, the air guide cover 213 can extend into the air inlet duct J or the air outlet duct C, or abut against the air inlet end of the air inlet duct J, or abut against the air outlet end of the air outlet duct C.

[0091] Further to the embodiments, please refer to Figure 4 and Figure 5 The flow area of ​​the air guide cover 213 decreases from one end close to the heat dissipation box door 210 to the other end. Specifically, the air guide cover 213 can be, but not limited to, a cone, a pyramid, etc. The air guide cover 20 is arranged between the air inlet duct J and the air inlet window 211. The airflow can be collected by the air guide cover 213 to speed up the airflow. The air guide cover 213 with a variable flow area is arranged between the air outlet duct C and the air outlet window 212, and the airflow outlet area is increased, which helps to increase the airflow flow.

[0092] In some embodiments, please refer to Figure 3 , multiple groups of battery clusters are arranged in the box 200, and each group of battery clusters is arranged in sequence along the length direction of the box 200, and the liquid cooling device 100 is arranged between adjacent battery clusters. At this time, the liquid cooling device 100 is arranged between the battery clusters, and the liquid cooling device 100 can be connected to the battery clusters on both sides through the liquid cooling pipe, and the length of the liquid cooling pipe is short, which can simplify the layout of the liquid cooling pipeline and reduce the pipeline cost.

[0093] In addition, the embodiment of the present application further provides a locomotive, including a locomotive head and the above-mentioned energy storage container 1000, and the energy storage container 1000 is used to supply power to the locomotive head. The locomotive head is a self-propelled vehicle that pulls or pushes railway vehicles for operation, but does not carry commercial loads itself, and it can use the energy storage container 1000 to supply power.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
