[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] like Figures 1-7As shown, the embodiment of the present application provides a direct cooling machine, which is applied to an energy storage container. The energy storage container comprises a cabinet body 1 and a door body 2. The door body 2 is connected to the cabinet body 1 in an openable and closable manner. The opening and closing of the cabinet body 1 can be realized by the action of the door body 2 relative to the cabinet body 1. For example, one side of the door body 2 is hinged to the cabinet body 1. The door body 2 is flipped relative to the cabinet body 1 to open and close the cabinet body 1.

[0036] The cabinet body 1 is provided with energy storage batteries 4 and heat exchange plates 5. The energy storage batteries 4, which can be used for photovoltaic energy storage, wind, light, water, fire, geothermal, tidal, nuclear, biomass, power grid and all other electric energy fields, are arranged above the heat exchange plates 5. The heat exchange plates 5 can be used for heat exchange of the energy storage batteries 4 to keep the energy storage batteries 4 at a suitable temperature and improve the reliability of the batteries. For example, a plurality of energy storage batteries 4 are provided, and a plurality of heat exchange plates 5 are also provided. Each energy storage battery 4 is arranged above the heat exchange plate 5.

[0037] The direct cooling machine comprises a direct cooling machine body 3 and a refrigerant pipeline 6. The direct cooling machine body 3 is arranged on the door body 2 of the energy storage container. Specifically, the direct cooling machine body 3 can be mounted on a part of the door body 2, or the door body 2 and the direct cooling machine body 3 can be arranged as an integrated structure, and the direct cooling machine body 3 is used as the door body 2 for opening and closing the cabinet body 1. The direct cooling machine body 3 and the heat exchange plate 5 are both provided with refrigerant interfaces. The refrigerant can flow into and out of the direct cooling plate and the heat exchange plate 5 through the refrigerant interfaces. The refrigerant pipeline 6 is connected between the refrigerant interfaces of the direct cooling machine body 3 and the heat exchange plate 5, thereby forming a refrigerant loop, i.e., the direct cooling machine body 3, the refrigerant pipeline 6 and the heat exchange plate 5 constitute a thermal management system. Here, the refrigerant interface comprises a refrigerant inlet and a refrigerant outlet. The refrigerant pipeline 6 comprises a first pipeline for flowing to the heat exchange plate 5 and a second pipeline for flowing to the direct cooling machine. During operation, as the compressor in the direct cooling plate operates, the refrigerant in the direct cooling machine body 3 flows out from the refrigerant outlet, flows into the heat exchange plate 5 through the first pipeline, and then flows out from the refrigerant outlet of the heat exchange plate 5 after phase change and heat exchange in the heat exchange plate 5. Finally, the refrigerant flows back to the direct cooling machine body 3 through the second pipeline.

[0038] The refrigerant pipeline 6 comprises at least a hose 7. For example, the refrigerant pipeline 6 can be partially provided with the hose 7, or all the pipeline segments can be provided with the hose 7. For example, the hose 7 can be an automobile air conditioner hose 7. The hose 7 is used to connect the refrigerant interfaces of the direct cooling machine body 3 and has the characteristics of deformable bending. Since the direct cooling machine body 3 is arranged on the door body 2, when the door body 2 is opened and closed relative to the cabinet body 1, the direct cooling machine body 3 also acts relative to the heat exchange plate 5 in the cabinet body 1. Through the deformation and bending of the hose 7, the connection reliability of the direct cooling machine body 3 and the heat exchange plate 5 can be ensured. Moreover, during assembly, the hose 7 can be directly connected with the direct cooling plate without pre-bending the angle, which is convenient and time-saving, and is conducive to improving the assembly efficiency.

[0039] In the scheme, the refrigerant pipeline 6 is connected with the refrigerant interface of the direct cooling machine body 3 through the quick mounting structure (such as the first quick mounting structure 11), that is, the hose 7 is connected with the refrigerant interface of the direct cooling machine body 3 through the quick mounting structure. Thus, during assembly, the quick mounting structure can realize the quick connection of the refrigerant pipeline 6 and the direct cooling machine body 3, which is beneficial to improve the installation efficiency.

[0040] Correspondingly, the refrigerant pipeline 6 is connected with the refrigerant interface of the heat exchange plate 5 through the quick mounting structure (such as the second quick mounting structure 12). Thus, during assembly, the quick mounting structure can realize the quick connection of the refrigerant pipeline 6 and the heat exchange plate 5, which is beneficial to improve the installation efficiency.

[0041] In some embodiments, the above-mentioned quick mounting structure includes a first connecting head and a second connecting head. One end of the first connecting head is connected to the end of the refrigerant pipeline 6, and the other end is provided with a first connecting part. The first connecting part is provided in a hollow tubular shape and communicates with the refrigerant pipeline 6. One end of the second connecting head is connected to the refrigerant interface of the direct cooling machine body 3 or the heat exchange plate 5, and the other end is provided with a second connecting part. The second connecting part is provided in a hollow tubular shape and communicates with the refrigerant interface of the direct cooling machine body 3 or the heat exchange plate 5. The first connecting part and the second connecting part are inserted and fitted, for example, the outer diameter of the first connecting part is matched with the inner diameter of the second connecting part, so that the first connecting part can be inserted into the second connecting part. For example, the first connecting head is provided as a male head, and the second connecting head is provided as a female head. During installation, the first connecting part is inserted into the second connecting part, so that the first connecting head and the second connecting head are communicated, and the refrigerant interface of the direct cooling machine body 3 or the heat exchange plate 5 and the refrigerant pipeline 6 are communicated. The operation is convenient, time-saving and labor-saving.

[0042] It should be noted that the second connecting head of the first quick mounting structure 11 communicates with the refrigerant interface of the direct cooling machine body 3, and the second connecting head of the second quick mounting structure 12 communicates with the refrigerant interface of the heat exchange plate 5. Moreover, the refrigerant interface and the second connecting head on the direct cooling machine body 3 or the heat exchange plate 5 can be provided as the same structural member, so as to save material cost and facilitate processing.

[0043] In order to improve the connection reliability, a sealing ring is provided around the outer periphery of the first connecting part. The sealing ring can be provided with one or more along the axis of the first connecting part, for example, two. Specifically, a sealing groove is opened in the outer periphery of the first connecting part, and the sealing ring is installed in the sealing groove and protrudes from the outer periphery of the first connecting part, so as to abut against the inner wall of the second connecting part. In this way, through the design of the sealing ring, the sealing between the first connecting part and the second connecting part can be improved, thereby preventing the refrigerant from leaking.

[0044] The first connecting head and the second connecting head are provided with a threaded assembly, the threaded assembly can realize the connection of the first connecting head and the second connecting head, so as to limit the second connecting part in the second connecting part, and further improve the connection strength. Wherein, the threaded assembly can be provided in the form of internal thread and external thread cooperation, for example, the first connecting head is provided with a nut, the second connecting head is provided with an external thread, the nut is rotated relative to the first connecting head and the second connecting head, and the connection of the first connecting head and the second connecting head can be realized. In addition, the threaded assembly can be provided in the form of screw connection, the first connecting head and the second connecting head are provided with threaded holes, and the screw is screwed in the two threaded holes to realize the connection of the first connecting head and the second connecting head.

[0045] In some embodiments, one side of the door body 2 is rotationally connected to the cabinet body 1, that is, the door body 2 can rotate relative to the cabinet body 1 along the first axis, which can be located at one side of the door body 2 or the axis of the hinge shaft between the door body 2 and the cabinet body 1. Wherein, the hose 7 is at least partially close to the first axis, for example, the middle part of the hose 7 is on the first axis, or the first axis is located on the inner side of the hose 7 after the hose 7 is bent. In this way, when the door body 2 is opened and closed relative to the cabinet body 1 along the first axis, part of the hose 7 can be bent along the first axis, thereby avoiding affecting the position of the direct cooling machine body 3 and the heat exchange plate 5, and improving the connection reliability of the direct cooling machine body 3 and the heat exchange plate 5. Moreover, it is beneficial to shorten the length of the refrigerant pipeline 6 and reduce the loss of cold energy.

[0046] Wherein, the refrigerant interface of the direct cooling machine body 3 is close to the first axis, that is, the refrigerant interface of the direct cooling machine body 3 is arranged on the side of the direct cooling machine body 3 close to the first axis, so as to further shorten the length of the refrigerant pipeline 6 and reduce the loss of cold energy.

[0047] As Figure 6As shown, in the first embodiment, the direct cooling machine main body 3 is internally provided with a shunt structure for shunting the refrigerant. Specifically, the direct cooling machine main body 3 is internally provided with a refrigerant circuit inlet and a refrigerant circuit outlet, the refrigerant circuit outlet is connected to multiple refrigerant interfaces through the shunt structure to shunt the refrigerant flowing out of the refrigerant circuit outlet to the multiple refrigerant interfaces, and the refrigerant circuit inlet is connected to the multiple refrigerant interfaces through the shunt structure to combine the refrigerant flowing into the multiple refrigerant interfaces to the refrigerant circuit inlet, thereby shunting the refrigerant into multiple parallel circuits. The direct cooling machine main body 3 is externally provided with multiple refrigerant interfaces (i.e., multiple refrigerant inlets and multiple refrigerant outlets), and similarly, the heat exchange plate 5 is provided with multiple refrigerant interfaces, and the refrigerant pipeline 6 is also provided with multiple refrigerant interfaces, thereby allowing the multiple refrigerant interfaces on the direct cooling machine main body 3 to be connected one-to-one to the refrigerant interfaces of the multiple heat exchange plates 5 (here, taking the heat exchange plate 5 provided with one refrigerant inlet and one refrigerant outlet as an example for illustration) through the multiple hoses 7. In this way, when connecting the direct cooling machine main body 3 and the heat exchange plate 5, only the two ends of the hose 7 need to be connected, which is simple to operate. Moreover, the shunt structure is located inside the direct cooling machine main body 3, which can be pre-assembled at the time of factory shipment, thereby avoiding complex pipelines and improving maintenance reliability.

[0048] The above-mentioned shunt structure includes a shunt 9 and multiple shunt pipes 10, one side of the shunt 9 is connected to the refrigerant circuit outlet or the refrigerant circuit inlet, and the other side is connected to the multiple shunt pipes 10, and each shunt pipe 10 is connected to one refrigerant interface. For example, the shunt 9 is provided in the form of a Venturi structure. Here, the shunt 9 is connected to the refrigerant circuit outlet or the refrigerant circuit inlet through a hard pipe 8, which can be provided in the form of a soft red copper pipe, thereby improving the reliability of the connection.

[0049] Among them, the shunt pipe 10 is provided in the form of a flexible capillary metal pipe, for example, the shunt pipe 10 is provided in the form of a soft red copper pipe with capillarity, and the shunt pipe 10 has a smaller aperture and a smaller wall thickness compared to the hard pipe 8. Since the shunt pipe 10 is provided in the form of a capillary, the refrigerant pressure inside the shunt 9 and the refrigerant flow rate inside the shunt pipe 10 can be improved, thereby improving the consistency of the refrigerant in each shunt pipe 10, which is conducive to achieving uniform temperature of the multiple energy storage batteries 4.

[0050] As Figure 7As shown, in the second embodiment, the refrigerant pipeline 6 comprises a hose 7 and a flow splitting structure for splitting the refrigerant. Specifically, the straight cooler body 3 is provided with a refrigerant circuit inlet and a refrigerant circuit outlet, and the outside of the straight cooler body 3 is provided with two refrigerant interfaces, one refrigerant inlet and one refrigerant outlet, the two refrigerant interfaces are respectively communicated with the refrigerant circuit outlet and the refrigerant circuit inlet, and the refrigerant pipeline 6 is also provided with two and is respectively connected with the two refrigerant interfaces of the straight cooler body 3. The heat exchange plates 5 are provided with a plurality of, each of the heat exchange plates 5 is provided with two refrigerant interfaces, one end of the flow splitting structure is connected with the hose 7, and the other end is connected with the refrigerant interfaces of the plurality of heat exchange plates 5 one by one. In this way, through the design of the flow splitting structure, the refrigerant can be distributed to the plurality of heat exchange plates 5, and then the plurality of energy storage batteries 4 can be simultaneously heat exchanged, which is beneficial to simplify the structure.

[0051] The above-mentioned flow splitting structure comprises a flow splitter 9 and a plurality of flow splitting pipes 10, one side of the flow splitter 9 is communicated with the hose 7, and the other side is communicated with the plurality of flow splitting pipes 10, and each of the flow splitting pipes 10 is communicated with one refrigerant interface on the heat exchange plate 5. For example, the flow splitter 9 is provided in the form of a Venturi structure. Here, the flow splitter 9 is communicated with the hose 7 through a hard pipe 8, which can be provided in the form of a soft red copper pipe, thereby improving the reliability of the connection, and preferably, the hose 7 is connected with the hard pipe 8 through a quick mounting structure.

[0053] The present application also provides an energy storage container comprising the straight cooler in the above-mentioned embodiments. In this way, when the door body 2 is opened and closed relative to the cabinet body 1, the straight cooler body 3 also acts relative to the heat exchange plates 5 in the cabinet body 1, and through the deformation and bending of the hose 7, the connection reliability of the straight cooler body 3 and the heat exchange plates 5 can be guaranteed.
