Description

[0001] The present application relates to the technical field of liquid-cooled energy storage containers, and in particular to a liquid-cooled energy storage container and a foldable radiator thereof. Background Art

[0002] In the related technology, the heat dissipation of the liquid-cooled energy storage container mainly relies on the liquid cooling unit system, and the liquid cooling unit system is mainly composed of coolant, radiator, cooling device, and control system. In the related technology, the liquid cooling unit can be installed in the liquid-cooled energy storage container as an independent device, or the liquid cooling unit system can be decoupled in the liquid-cooled energy storage container to achieve the electromechanical integration of the liquid cooling system and the energy storage container. In the process of decoupling the functions of the liquid cooling unit system, the radiator, as an important component of the liquid cooling unit, is a thorny problem to reasonably install the radiator on the energy storage container.

[0032] The present application proposes a foldable radiator, which can be applied to the heat dissipation of power consumption components in a liquid-cooled energy storage container. Of course, the foldable radiator is not limited to liquid-cooled energy storage containers.

[0033] like Figure 1 As shown, a foldable heat sink provided by an embodiment of the present application includes a telescopic fin structure 100 , and the telescopic fin structure 100 can be folded or unfolded in a first direction X. The first direction X is its telescopic direction. Figure 1 , the first direction X is specifically along the left-right direction. Figure 1 In the figure, the foldable radiator is in a folded state. Figure 2 and Figure 3 As shown, the telescopic fin structure 100 can be expanded to different degrees in its first direction X to adapt to different environmental space requirements.

[0034] like Figure 1 As shown, the telescopic fin structure 100 includes at least one telescopic unit 10 hinged in sequence along a first direction X, and each telescopic unit 10 is provided with an internal channel 101. When the foldable radiator switches between the folded state and the unfolded state, the size of the telescopic unit 10 in the first direction X decreases or increases. Figure 1 The range shown in the dashed box. It should be emphasized that Figure 1 The telescopic unit 10 shown in the dotted box is X-shaped, but is not limited to the X-shape, and can be, for example, V-shaped. Figure 1 Only three telescopic units 10 are shown in the figure. The number of the telescopic units 10 is not limited to three, and may be more than three; the number of the telescopic units 10 may also be less than three, for example, the number of the telescopic units 10 is two or one.

[0035] The internal channels 101 in adjacent telescopic units 10 are connected at the hinge points of the adjacent telescopic units 10, so that the internal channels 101 in all telescopic units 10 jointly define the coolant flow channel of the telescopic fin structure 100. In addition, the telescopic fin structure 100 is provided with at least two openings 102, and the openings 102 connect the coolant flow channel with the external space. The coolant flow channel can be connected to the cooling pipe of the liquid-cooled energy storage container through the openings 102 to form a cooling circuit, so that the power consumption components in the box body of the liquid-cooled energy storage container can be cooled.

[0036] Taking the telescopic fin structure 100 with two openings 102 as an example, the two openings 102 are used as a liquid inlet and a liquid outlet respectively, and the coolant flows into the coolant flow channel of the telescopic fin structure 100 from the liquid inlet, and then flows out of the coolant flow channel from the liquid outlet, thereby dissipating heat for the above-mentioned power consumption components. When the openings 102 on the telescopic fin structure 100 are greater than two, the opening 102 used as the liquid inlet may not be limited to one, the opening 102 used as the liquid outlet may not be limited to one, or the opening 102 used as the liquid inlet and the opening 102 used as the liquid outlet are not limited to one.

[0037] The telescopic fin structure 100 has the characteristics of being foldable and unfoldable, so it can meet the transportation and use requirements of the liquid-cooled energy storage container. Specifically, the foldable radiator can be set on the outer surface of the box body of the liquid-cooled energy storage container. During transportation, the foldable radiator can be folded to reduce the occupied space, so as to meet the transportation requirements; when it is used on site, the foldable radiator is unfolded to increase the contact area between the foldable radiator and the surrounding environment, improve the heat exchange efficiency between the radiator and the surrounding environment, and then reduce the energy consumption of the energy storage system.

[0038] refer to Figures 1 to 3In some embodiments, the telescopic unit 10 of the telescopic fin structure 100 includes a plurality of fins hinged together, each fin having an inner cavity 104 and the inner cavities 104 of each fin are connected at the hinge, and the fins of adjacent telescopic units 10 are hinged to form a plurality of hinge points and the inner cavities 104 are connected. In the same telescopic unit 10, the hinge of the fin is provided with an opening 102, and the opening 102 is connected to the inner cavity 104 of the fin; and / or, each hinge point is provided with an opening 102, and the opening 102 is connected to the inner cavity 104 of the fin. The telescopic unit 10 includes a plurality of fins hinged together, and a telescopic fin structure 100 of any length may be required.

[0039] Each telescopic unit 10 is not limited to the above-mentioned method of including a plurality of fins hinged together. In other embodiments, each telescopic unit 10 is hinged end to end in sequence along the first direction X to form a telescopic fin structure 100. For example, each telescopic unit 10 is a sheet-like elastic member, and each telescopic unit 10 is connected in sequence. When the telescopic fin structure 100 is unfolded, each telescopic unit 10 is elongated in the first direction X; when the telescopic fin structure 100 is folded, each telescopic unit 10 is shortened relative to each other in the first direction X.

[0040] Several implementations of the telescopic fin structure 100 when it is formed by a plurality of fins hinged together are exemplarily given below. However, it should be emphasized that the implementation of the telescopic fin structure 100 is not limited to these implementations.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the telescopic unit 10 includes a rotation node 110, a first fin 120, a second fin 330, a third fin 140 and a fourth fin 150 connected to the rotation node 110 for relative rotation. A cavity 103 is provided inside the rotation node 110, and an inner cavity 104 of each fin is communicated with the cavity 103. The cavity 103 and the inner cavity 104 jointly define an internal passage 101 of the telescopic unit 10. Each fin has a hinge end 160 for hinged connection with the fin of the adjacent telescopic unit 10. The first fin 120 is used for hinged connection with the third fin 140 of the adjacent telescopic unit 10, and the second fin 130 is used for hinged connection with the fourth fin 150 of the adjacent telescopic unit 10. The hinge end 160 of each fin is provided with an opening 102; and / or, each rotation node 110 is provided with an opening 102.

[0042] Specifically, each fin has an opening 102 at its hinged end 160, and each rotation node 110 has an opening 102. Each opening 102 is allowed to be used as a liquid inlet or a liquid outlet. Thus, this design provides a variety of possibilities for the pipe connection between the foldable radiator and the liquid cooling unit 410 of the liquid-cooled energy storage container, greatly increasing the convenience of use.

[0043] In addition, each fin and the rotation node 110 are configured to be relatively rotatable and have internal spaces connected, which can be achieved in a variety of ways, and the first fin 120 is used as an example below. For example, the first fin 120 is connected to the rotation node 110 through a flexible pipe (such as a rubber pipe), so that they can maintain internal space communication when they rotate relative to each other. For another example, the first fin 120 is connected to the rotation node 110 and forms a rotating pipe joint structure.

[0044] Furthermore, the telescopic fin structure 100 further includes a folding and unfolding driving mechanism, which is connected to the telescopic unit 10 at the head end or the telescopic unit 10 at the tail end to drive the telescopic fin structure 100 to automatically fold or unfold. Exemplarily, a crank structure is connected to the rotation node 110 of the telescopic unit 10 at the head end, and when the crank structure rotates, the telescopic unit 10 at the head end is driven to rotate relative to other telescopic units 10, so that the telescopic fin structure 100 can be automatically folded or unfolded.

[0045] In another embodiment, the telescopic unit 10 includes a first fin and a second fin that are cross-hinged together. Figure 2 The first fin 120 and the fourth fin 150 are connected as a whole; the second fin is equivalent to the second fin 130 and the third fin 140 being connected as a whole. The first fin and the second fin both have an inner cavity 104, and the inner cavity 104 of the first fin and the inner cavity 104 of the second fin are connected at the hinge. The first fin and the second fin of the adjacent telescopic units 10 are hinged together and the inner cavities 104 of the two are connected.

[0046] Specifically, the first fin is located on one side of the second fin and the two are arranged crosswise in an X shape. The cylinder can be used as a pivot at the intersection of the two fins. At the same time, the cylinder is connected to the inner cavity 104 of the first fin and the second fin, and the connection is sealed. At this time, the first fin and the second fin each have two hinge ends 160. In the first direction X, the two hinge ends of the first fin are respectively hinged to one hinge end of the second fin on both sides.

[0047] In another embodiment, referring to Figure 4 The telescopic unit 10 includes a first fin 120 and a second fin 130 that are cross-hinged together. The first fin 120 is hollow and one end is provided with a first spherical hinge end 121; the second fin 130 is hollow and one end is provided with a second spherical hinge end 131, the second spherical hinge end 131 and the first spherical hinge end 121 are nested and can rotate relatively, and the second spherical hinge end 131 and the first spherical hinge end 121 are connected. The other end of the first fin 120 and the other end of the second fin 130 respectively form an opening 102.

[0048] In some embodiments, reference Figures 1 to 3 Along the first direction X, at least the telescopic units 10 at the head and tail ends of the telescopic fin structure 100 are respectively provided with at least one opening 102 communicating with the internal channel 101. The telescopic fin structure 100 can form a first coolant circuit with the first flexible tube 200 and the second flexible tube 300.

[0049] It should be noted that in this application, the head end and the tail end are relative, and there is no specific position limitation. Figures 1 to 3 When the number of telescopic units 10 is three or more, the telescopic unit 10 at the head end may be the telescopic unit 10 at the left end, and the telescopic unit 10 at the tail end refers to the telescopic unit 10 at the right end. When the number of telescopic units 10 is two, the two telescopic units 10 are the telescopic unit 10 at the head end and the telescopic unit 10 at the tail end. When the number of telescopic units 10 is one, the telescopic unit 10 at the head end and the telescopic unit 10 at the tail end are the same.

[0050] For example, Figure 1 and Figure 2 As shown, the first flexible tube 200 is connected to the opening 102 on the telescopic unit 10 at the head end along the first direction X; the second flexible tube 300 is connected to the opening 102 on the telescopic unit 10 at the tail end along the first direction. At this time, the unused openings 102 on each telescopic unit 10 can be blocked or directly cancelled during design. When in use, the coolant can flow in from the telescopic unit 10 at the head end and then flow out from the telescopic unit 10 at the tail end, the liquid inlet direction is shown by arrow A, and the liquid outlet direction is shown by arrow B. In this way, the coolant will have better fluidity inside the telescopic fin structure 100, so that the telescopic fin structure 100 has better heat dissipation efficiency.

[0051] refer to Figures 1 to 3 , taking the number of telescopic units 10 as three as an example, at least the telescopic units 10 at the left end and the right end are respectively provided with openings 102. When in use, the telescopic unit 10 at the left end can be used as the telescopic unit 10 at the head end. In this way, the opening 102 on the telescopic unit 10 at the head end is connected to the first flexible tube 200 as a liquid inlet, and the opening 102 on the telescopic unit 10 at the tail end is connected to the second flexible tube 300 as a liquid outlet. The coolant can flow in from the telescopic unit 10 at the head end and then flow out from the telescopic unit 10 at the tail end. The flow direction of the coolant is generally along the first direction X, so that the fluidity of the coolant inside the telescopic fin structure 100 will be better, so that the telescopic fin structure 100 has better heat dissipation efficiency.

[0052] The position of the opening 102 on the telescopic unit 10 at the left end can be set flexibly. Figures 1 to 3As shown, in the second direction Y, the telescopic unit 10 at the left end is provided with openings 102 on both sides and in the middle. In other embodiments, the opening 102 on the telescopic unit 10 at the left end can be provided on one of the two sides of the telescopic unit 10 in the second direction Y, and / or provided in the middle of the telescopic unit 10. Similarly, the position of the opening 102 on the telescopic unit 10 at the right end is flexible and will not be repeated. In the present application, the first direction X is the telescopic direction of the telescopic fin structure 100, which is also its length direction. The second direction Y is the width direction of the telescopic fin structure 100.

[0053] In some embodiments, the opening 102 on the telescopic unit at the head end is located in the middle of the telescopic unit at the head end, and the opening 102 on the telescopic unit at the tail end is located in the middle of the telescopic unit at the tail end. In this case, the telescopic fin structure 100 can form a second cooling liquid circuit with the first flexible tube 200 and the second flexible tube 300.

[0054] Specifically, Figures 5 to 7 As shown, at this time, the foldable radiator and the flexible pipe of the liquid-cooled energy storage container adopt the second connection method. Specifically, the opening 102 connected to the first flexible pipe 200 and the opening 102 connected to the second flexible pipe 300 are arranged along the first direction X. Specifically, the opening 102 connected to the first flexible pipe 200 is located in the middle of the telescopic unit 10 at the head end, and the opening 102 connected to the second flexible pipe 300 is located in the middle of the telescopic unit 10 at the tail end. After the coolant flows into the telescopic unit 10, it flows from the middle of the telescopic unit 10 to multiple directions, but the liquid generally flows along the first direction X, so that it can flow through each telescopic unit 10 in sequence to obtain a better heat dissipation effect.

[0055] For example, the telescopic unit 10 includes a rotation node 110, a first fin 120, a second fin 330, a third fin 140, and a fourth fin 150 that are relatively rotatably connected to the rotation node 110. The first flexible tube 200 is connected to the opening 102 on the rotation node 110 of the telescopic unit 10 at the head end, and the second flexible tube 300 is connected to the opening 102 on the rotation node 110 of the telescopic unit 10 at the tail end.

[0056] In other embodiments, the telescopic unit at the head end is provided with at least two openings 102 arranged along the second direction Y, and the telescopic unit at the tail end is provided with at least two openings 102 arranged along the second direction Y, and the second direction Y is perpendicular to the first direction X. In this way, the telescopic fin structure 100 can form a cooling liquid circuit of a third connection mode with the first flexible tube 200 and the second flexible tube 300.

[0057] Specifically, Figures 1 to 3As shown, specifically, the first flexible tube 200 is connected to at least two openings 102 on the telescopic unit 10 at the head end, and the second flexible tube 300 is connected to at least two openings 102 on the telescopic unit 10 at the tail end. In addition, the arrangement direction of all the openings 102 connected to the first flexible tube 200 is parallel to the second direction Y, and the arrangement direction of all the openings 102 connected to the second flexible tube 300 is parallel to the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0058] More specifically, take the telescopic unit 10 including the rotation node 110, the first fin 120, the second fin 330, the third fin 140 and the fourth fin 150 connected to the rotation node 110 for relative rotation, and the hinge end 160 of each fin is respectively provided with an opening 102 as an example. The arrangement direction of the opening 102 on the first fin 120 and the opening 102 on the second fin 130 in the telescopic unit 10 at the head end is parallel to the second direction Y. The arrangement direction of the opening 102 on the third fin 140 and the opening 102 on the fourth fin 150 in the telescopic unit 10 at the tail end is parallel to the second direction Y. The first flexible tube 200 is connected to the opening 102 on the first fin 120 and the opening 102 on the second fin 130 on the telescopic unit 10 at the head end. The second flexible tube 300 is connected to the opening 102 on the third fin 140 and the opening 102 on the fourth fin 150 on the telescopic unit 10 at the tail end.

[0059] In the above manner, the coolant in the first flexible tube 200 flows into the telescopic unit 10 at the head end from the two openings 102; at the same time, the coolant flows out from the two openings 102 of the telescopic unit 10 at the tail end and converges into the second flexible tube 300. The coolant can flow into and out of the telescopic fin structure 100 quickly, thereby having a higher heat dissipation efficiency.

[0060] In some other embodiments, openings 102 are respectively provided on each telescopic unit 10 on both sides of the telescopic fin structure 100 along a second direction Y perpendicular to the first direction X. In this way, all openings 102 on the same side can be used as liquid inlets or liquid outlets at the same time, thereby increasing the speed at which the coolant flows into or out of the telescopic fin structure 100, thereby improving the heat dissipation efficiency. In this way, the telescopic fin structure 100 can form a coolant circuit of a third connection mode with the first flexible tube 200 and the second flexible tube 300.

[0061] Specifically, Figure 8 and Fig. 9As shown, along the second direction Y perpendicular to the first direction X, openings 102 are respectively provided on each telescopic unit 10 on both sides of the telescopic fin structure 100, so that each side of the telescopic fin structure 100 has a row of openings 102. The first flexible tube 200 and the second flexible tube 300 are respectively located on both sides of the telescopic fin structure 100, wherein the first flexible tube 200 is connected to one row of openings 102, and the first flexible tube 200 is connected to the other row of openings 102. Specifically, openings 102 are respectively provided on both sides of each telescopic unit 10, and the openings 102 can be provided on the hinged end 160 of the fin.

[0062] After such arrangement, the overall direction of the coolant is along the second direction Y; and the coolant enters the telescopic fin structure 100 from multiple openings 102 at the same time, and leaves the telescopic fin structure 100 from multiple openings 102. A large amount of coolant can exchange heat with the outside in a short time, so that the folding radiator can have a higher heat dissipation efficiency.

[0063] refer to Fig.10 One embodiment of the present application further provides a liquid-cooled energy storage container, comprising a container body 400, and a folding radiator according to any of the above embodiments. An energy storage unit (not shown) and a liquid cooling unit 410 are arranged in the container body 400. The telescopic fin structure 100 of the folding radiator is arranged in the container body 400 and can be switched between an unfolded state and a folded state.

[0064] like Fig.10 As shown in the transport state (a) in the figure, the foldable radiator can be folded to reduce the occupied space during transportation, thus meeting the transportation requirements. Fig.10 As shown in the usage state (b) in the figure, the foldable radiator is unfolded at the application site to increase the contact area between the foldable radiator and the surrounding environment, thereby improving the heat exchange efficiency between the radiator and the surrounding environment, and then reducing the energy consumption of the energy storage system.

[0065] In some embodiments, when the foldable radiator is in the folded state, the foldable radiator is located within the outer contour of the container body 40. Exemplarily, the telescopic fin structure 100 of the foldable radiator can be fixed to a recessed area on the outer surface of the container body 400. In this way, when the foldable radiator is in the folded state, its edge does not exceed the outer contour coverage of the container body 40, and does not occupy additional space.

[0066] In some embodiments, the liquid-cooled energy storage container includes the aforementioned first flexible tube 200 and second flexible tube 300. The first flexible tube 200 is in communication with at least one opening 102 of the foldable radiator. The second flexible tube 300 is in communication with at least one opening 102, the second flexible tube 300 and the first flexible tube 200 are connected to different openings 102, the second flexible tube is in communication with the liquid inlet of the liquid cooling unit 410, and the first flexible tube 200 is in communication with the liquid outlet of the liquid cooling unit 410. In combination with the foregoing, the first flexible tube 200 and the second flexible tube 300 and the telescopic fin structure 100 of the foldable radiator can constitute cooling circuits in different ways.

[0067] Finally, it should be noted that the various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various 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.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent 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 patent application shall be subject to the attached claims.
