For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0058] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0059] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this utility model include direct and indirect connections (couplings) unless otherwise specified.

[0060] In order to simplify the structure of the water cooling device in the existing ultrasonic equipment, some embodiments of the present invention provide a liquid cooling device for medical equipment (such as ultrasonic equipment or other types of medical equipment). In the liquid cooling device, the hot liquid joint and the cold liquid joint are installed on the end of the liquid pipe heat dissipation module, and there is no need to set a crossbeam across the two ends of the liquid pipe heat dissipation module, which can avoid the problem of difficult processing and assembly due to the suspended crossbeam, making the liquid pipe heat dissipation module structure simpler and easier to manufacture.

[0061] Specifically, taking an ultrasonic device as an example, of course, in other embodiments, the ultrasonic device may also be replaced by other types of medical devices.

[0062] Please refer to Figure 1 In some embodiments, the liquid cooling device 100 includes at least one cooling head 110 for contact cooling of the heat source of the ultrasonic device, a liquid pipe cooling module 120 for cooling the cooling liquid, and at least one driving member 130 for driving the cooling liquid to flow (see Figures 11 - 15 ). The driving member 130 may be a water pump or other driving member 130 that can drive the coolant to flow. The cooling head 110 is in direct or indirect contact with the corresponding heat source to transfer the heat emitted by the heat source to the cooling head 110 to cool the heat source. Driven by the driving member 130, the coolant can flow through the cooling head 110 and take away the heat of the cooling head 110, thereby cooling the cooling head 110. The cooling head 110 can form a coolant circulation liquid path with the liquid tube heat dissipation module 120 through the corresponding circulation pipeline. The driving member 130 can be arranged in one or more coolant circulation liquid paths, and can also be arranged in the liquid tube heat dissipation module 120, so as to drive the coolant in each coolant circulation liquid path.

[0063] Please refer to Figures 2 - 5, in some embodiments, the liquid pipe heat dissipation module 120 has a heat dissipation liquid pipe 121, a cold liquid collecting end 122 and a hot liquid collecting end 123. The heat dissipation liquid pipe 121 can be one or more than two. Each heat dissipation liquid pipe 121 has a cold liquid port and a hot liquid port arranged oppositely, and the cooling liquid flows from the hot liquid port to the cold liquid port. Among them, the cold liquid port and the hot liquid port are defined to distinguish the two ends of the heat dissipation liquid pipe 121, and their hot and cold are relative. That is, in the same heat dissipation liquid pipe 121, the opening corresponding to the end where the liquid inside is hotter is the hot liquid port, and the opening corresponding to the end where the liquid inside is cooler is the cold liquid port. The heat dissipation liquid pipe 121 can be made of a material that is easy to dissipate heat, such as a metal material or other pipe materials that can be used as a cooling liquid heat dissipation in the liquid cooling device 100. The shape of the heat dissipation liquid pipe 121 can also be designed to be a shape that is convenient for heat dissipation. For example, please refer to Figure 3 and 5 , in some embodiments, the heat dissipation liquid pipe 121 adopts a flat pipe shape. The heat dissipation liquid pipe 121 with a flat pipe shape has a larger side wall. At this time, heat dissipation materials, such as heat dissipation fins 124, etc., can also be filled between adjacent heat dissipation liquid pipes 121 to help the heat dissipation liquid pipe 121 dissipate heat. The side wall area of the heat dissipation liquid pipe 121 with a flat pipe shape is larger, which can increase the heat dissipation area with the heat dissipation fins 124 to achieve faster heat exchange and improve the heat dissipation efficiency.

[0064] Driven by the driving member 130, the liquid in the heat dissipation liquid pipe 121 flows from one end of the hot liquid port to one end of the cold liquid port. During the process of the cooling liquid flowing in the heat dissipation liquid pipe 121, the heat of the liquid is transferred to the heat dissipation liquid pipe 121 and dissipated through the heat dissipation liquid pipe 121, thereby cooling the cooling liquid.

[0065] Please refer to Figures 2 - 5 , in some embodiments, the cold liquid collecting end 122 is installed at the cold liquid port of the corresponding heat dissipation liquid pipe 121, and the hot liquid collecting end 123 is installed at the hot liquid port of the corresponding heat dissipation liquid pipe 121. A cold liquid joint 125 for directly communicating with the circulation pipeline is provided on the cold liquid collecting end 122, and a hot liquid joint 126 for directly communicating with the circulation pipeline is provided on the hot liquid collecting end 123. The cooling head 110 is connected to the cold liquid joint 125 and the hot liquid joint 126 through the circulation pipeline to form a cooling liquid circulation circuit for cooling the cooling head 110. Thus, the beam structure is omitted in this structure, making the structure of the liquid cooling device 100 simpler and having lower difficulty in manufacturing and assembly.

[0066] Regarding the number of the heat dissipation liquid pipes 121, it can be one, or two or more. When there is one heat dissipation liquid pipe 121, the cold liquid collecting end 122 and the hot liquid collecting end 123 can be directly installed at both ends of the heat dissipation liquid pipe 121.

[0067] When the number of the heat dissipation liquid pipes 121 is two or more, in some embodiments, the heat dissipation liquid pipes 121 can be divided into at least two groups, and the hot and cold directions of all the heat dissipation liquid pipes 121 within each group are the same. The hot and cold directions between different groups of heat dissipation liquid pipes 121 can be the same or different. For example, in Figure 3 and 5 In the illustrated embodiment, the heat dissipation liquid pipes 121 of the liquid pipe heat dissipation module 120 are at least divided into a first liquid pipe unit 1211 and a second liquid pipe unit 1212, and each liquid pipe unit can have one or more heat dissipation liquid pipes 121. Among them, the hot liquid port of the first liquid pipe unit 1211 and the cold liquid port of the second liquid pipe unit 1212 are at the same end, and the cold liquid port of the first liquid pipe unit 1211 and the hot liquid port of the second liquid pipe unit 1212 are at the same end. Of course, in other embodiments, it can also be set that the cold liquid ports of the first liquid pipe unit 1211 and the second liquid pipe unit 1212 are at the same end, and the hot liquid ports of the first liquid pipe unit 1211 and the second liquid pipe unit 1212 are at the same end.

[0068] At this time, within each liquid pipe unit, a common cold liquid collecting end 122 and a common hot liquid collecting end 123 can be shared to simplify the structure and reduce the manufacturing and assembly difficulty. Of course, in other embodiments, two or more cold liquid collecting ends 122 and two or more hot liquid collecting ends 123 can also be respectively provided within each liquid pipe unit.

[0069] Specifically, please refer to Figure 3 and 5 , in some embodiments, when a common cold liquid collecting end 122 and a common hot liquid collecting end 123 can be shared within each liquid pipe unit, the cold liquid collecting end 122 corresponding to the first liquid pipe unit 1211 is the first cold liquid collecting end 1221, the hot liquid collecting end 123 corresponding to the first liquid pipe unit 1211 is the first hot liquid collecting end 1231, the cold liquid collecting end 122 corresponding to the second liquid pipe unit 1212 is the second cold liquid collecting end 1222, and the hot liquid collecting end 123 corresponding to the second liquid pipe unit 1212 is the second hot liquid collecting end 1232.

[0070] In some embodiments, liquid connectors are respectively provided on the first cold liquid collecting end 1221, the first hot liquid collecting end 1231, the second cold liquid collecting end 1222, and the second hot liquid collecting end 1232 as needed. For example, in Figure 3 and 5 In the illustrated embodiment, liquid connectors are respectively provided on the first cold liquid collecting end 1221, the first hot liquid collecting end 1231, the second cold liquid collecting end 1222, and the second hot liquid collecting end 1232.

[0071] In one embodiment, as in Figure 2 and4 As shown, the first liquid pipe unit 1211 and the second liquid pipe unit 1212 are adjacently connected and both extend along the first direction (as shown by a in Figure 2 ), that is, the extending directions of the first liquid pipe unit 1211 and the second liquid pipe unit 1212 (referring to the pipeline direction, not the cold and hot direction) are the same, so that a more regular structure can be formed. At this time, the first cold liquid collecting end 1221 and the second hot liquid collecting end 1232 are located on the first side of the liquid pipe heat dissipation module 120, and the second cold liquid collecting end 1222 and the first hot liquid collecting end 1231 are located on the second side of the liquid pipe heat dissipation module 120, where the first side and the second side are the opposite sides of the liquid pipe heat dissipation module 120 in the first direction. In addition, in other embodiments, the first liquid pipe unit 1211 and the second liquid pipe unit 1212 may also extend and be arranged in different directions, or the first liquid pipe unit 1211 and the second liquid pipe unit 1212 are separated from each other.

[0072] Furthermore, the first cold liquid collecting end 1221, the first hot liquid collecting end 1231, the second cold liquid collecting end 1222, and the second hot liquid collecting end 1232 may be separated from each other, or may be partially integrated into an integrated structure.

[0073] For example, in some embodiments, please refer to Figure 2 and 3 , the liquid pipe heat dissipation module 120 includes a first general end 1271, and the first general end 1271 has an integrated first box body 1273 and a first partition body 1274. The first partition body 1274 hermetically divides the first box body 1273 into a first cold liquid collecting end 1221 and a second hot liquid collecting end 1232. The cold liquid ports of the heat dissipation liquid pipes 121 in the first liquid pipe unit 1211 are all communicated with the cavity of the first cold liquid collecting end 1221, and the hot liquid ports of the heat dissipation liquid pipes 121 in the second liquid pipe unit 1212 are all communicated with the cavity of the second hot liquid collecting end 1232. Using the above integrated structure, not only can the functions of the first cold liquid collecting end 1221 and the second hot liquid collecting end 1232 be realized through a simpler structure, but also the first cold liquid collecting end 1221 and the second hot liquid collecting end 1232 are integrated on the first box body 1273 and are fixedly connected to the first liquid pipe unit 1211 and the second liquid pipe unit 1212 at the same time, and can also play a role in fixing the first liquid pipe unit 1211 and the second liquid pipe unit 1212, so that the first liquid pipe unit 1211 and the second liquid pipe unit 1212 form a complete fixed structure, improving the stability of the entire liquid pipe heat dissipation module 120.

[0074] And / or, in some embodiments, please refer to Figure 2 and 5, the liquid pipe heat dissipation module 120 includes a second general end 1272, and the second general end 1272 has an integrated second box body 1275 and a second partition 1276. The second partition 1276 hermetically divides the second box body 1275 into a second cold liquid collecting end 1222 and a first hot liquid collecting end 1231. With the above integrated structure, not only can the liquid collecting function of the second cold liquid collecting end 1222 and the first hot liquid collecting end 1231 be realized through a simpler overall structure, but also the first cold liquid collecting end 1221 and the second hot liquid collecting end 1232 are integrated on the first box body 1273 and fixedly connected to the first liquid pipe unit 1211 and the second liquid pipe unit 1212 at the same time, which can also play a role in fixing the first liquid pipe unit 1211 and the second liquid pipe unit 1212, making the first liquid pipe unit 1211 and the second liquid pipe unit 1212 form a complete fixed structure and improving the stability of the entire liquid pipe heat dissipation module 120.

[0075] Of course, in other embodiments, the first cold liquid collecting end 1221 and the second hot liquid collecting end 1232 can also be independent into two separate ends, and the first hot liquid collecting end 1231 and the second cold liquid collecting end 1222 can also be independent into two separate ends.

[0076] Furthermore, the cooling head 110 dissipates heat through the flow of the coolant. In some embodiments, the cooling head 110 can be at least one. Among them, each cooling head 110 can correspondingly contact one or more heat sources, or multiple cooling heads 110 contact the same heat source to achieve heat dissipation.

[0077] Please refer to Figure 1 , in some embodiments, the cooling head 110 is at least divided into a first cooling head 111, a second cooling head 112, and a third cooling head 113. Among them, for the convenience of description, the circulation pipeline corresponding to the first cooling head 111 is divided into a first cold liquid pipeline 1111 and a first hot liquid pipeline 1112, the circulation pipeline corresponding to the second cooling head 112 is divided into a second cold liquid pipeline 1121 and a second hot liquid pipeline 1122, and the circulation pipeline corresponding to the third cooling head 113 is divided into a third cold liquid pipeline 1131 and a third hot liquid pipeline 1132.

[0078] Please continue to refer to Figure 1 and 2, in some embodiments, the first cold liquid pipeline 111 and the second cold liquid pipeline 1121 are communicated with the cold liquid joint 125 of the first cold liquid collecting end 1221, the first hot liquid pipeline 1112 and the second hot liquid pipeline 1122 are communicated with the hot liquid joint 126 of the second hot liquid collecting end 1232, the third cold liquid pipeline 1131 is communicated with the cold liquid joint 125 of the second cold liquid collecting end 1222, and the third hot liquid pipeline 1132 is communicated with the hot liquid joint 126 of the first hot liquid collecting end 1231. Of course, in other embodiments, the first cooling head 111, the second cooling head 112, and the third cooling head 113 may also be connected to the corresponding hot and cold joints in other forms.

[0079] Please refer to Figure 1 , in some embodiments, the first cooling head 111, the second cooling head 112, and the third cooling head 113 are arranged along the first direction (as shown by a in Figure 2 ), that is, the arrangement direction of the first cooling head 111, the second cooling head 112, and the third cooling head 113 is the same as the extending direction of the heat dissipation liquid pipe 121, so as to form a more regular structure. In addition, in some embodiments, the arrangement direction of the cooling head 110 and the extending direction of the heat dissipation liquid pipe 121 may also be set to be inconsistent.

[0080] Please refer to Figure 6 , in a more specific embodiment, when the liquid cooling device 100 is applied to the ultrasound mainframe of an ultrasound device (which may also be other types of medical devices), the ultrasound mainframe has a housing (not shown in the figure) and a board card assembly 210. The board card assembly 210 and the liquid cooling device 100 are arranged in the housing. Among them, the board card assembly 210 includes at least one board card for data processing (such as 211, 212, 213), and the board card can be a GPU control board card and / or a CPU control board card. The cooling head 110 can be in direct or indirect contact with the board card to perform contact heat dissipation on the board card.

[0081] Furthermore, when the board card assembly 210 has multiple board cards, due to the very compact internal structure and limited space of the ultrasound mainframe, how to simultaneously dissipate heat from multiple board cards in a compact space at this time poses higher requirements for the structural arrangement of the liquid cooling device 100.

[0082] Please refer to Figure 6 , in some embodiments, taking the board cards being at least divided into a first board card 211, a second board card 212, and a third board card 213 as an example, the first board card 211, the second board card 212, and the third board card 213 are along the first direction (such as Figure 6They are arranged in sequence as shown in a). In order not to overly affect the positions of the original components in the ultrasound main unit and not to occupy too much space, the liquid pipe heat dissipation module 120 also extends along the first direction and is arranged below the circuit board. The first cooling head 111 is used to dissipate heat from the first circuit board 211, the second cooling head 112 is used to dissipate heat from the second circuit board 212, and the third cooling head 113 is used to dissipate heat from the third circuit board 213. Among them, for the second cold liquid pipeline 1121 corresponding to the second cooling head 112, starting from the cold liquid collection end 122, it bypasses from below the first circuit board 211 or the third circuit board 213 to the second cooling head 112. The second hot liquid pipeline 1122 starts from the second cooling head 112 and bypasses from below the first circuit board 211 or the third circuit board 213 to the hot liquid collection end 123. Through this structure, a more compact structure can be formed between the cooling head 110 and its corresponding circulation pipeline and each circuit board, so as to reduce the volume of the ultrasound main unit.

[0083] In particular, please refer to Figure 6 , in some embodiments, the bottom of the first circuit board 211 is lower than the bottom of the second circuit board 212, so that the pipe routing space between the liquid pipe heat dissipation module 120 and the first circuit board 211 becomes very small. Since the circulation pipeline requires a certain bending space, if the liquid pipe heat dissipation module 120 is moved downward at this time to expand the pipe routing space, the volume of the entire structure will increase. For this problem, please refer to Figure 2 and 6 , in some embodiments, the cold liquid joint 125 includes a second cold liquid joint 1252 communicated with the second cold liquid pipeline 1121, and the hot liquid joint 126 includes a second hot liquid joint 1262 communicated with the second hot liquid pipeline 1122. Both the second cold liquid joint 1252 and the second hot liquid joint 1262 are elbows with transverse docking parts 1252a and 1262a. The connection parts where the second cold liquid pipeline 1121 and the second hot liquid pipeline 1122 are respectively docked with the corresponding transverse docking parts 1252a and 1262a are both arranged horizontally, so that the second cold liquid pipeline 1121 and the second hot liquid pipeline 1122 form a tendency to extend in the horizontal direction starting from the second cold liquid joint 1252 and the second hot liquid joint 1262, so as to more easily pass under the first cooling head 111 or the third cooling head 113, and the second cold liquid pipeline 1121 and the second hot liquid pipeline 1122 can pass under the first cooling head 111 or the third cooling head 113 without bending, thereby reducing the space occupation.

[0084] Specifically, in some embodiments, as Figure 2 shown, the second cold liquid joint 1252 and the second hot liquid joint 1262 can adopt right-angle elbows or other joints that can form transverse docking parts. Of course, please refer to Figure 7 , in some other embodiments, the second cold liquid joint 1252 and the second hot liquid joint 1262 can adopt straight heads or joints of other shapes.

[0085] Please refer to Figure 1 that, in some embodiments, the first cold liquid joint 1251 communicating with the first cold liquid pipeline 111 and the first hot liquid joint 1261 communicating with the first hot liquid pipeline 1112 are located below the first cooling head 111. At this time, the first cold liquid joint 1251 and the first hot liquid joint 1261 can also be straight heads facing upward. Of course, in other embodiments, the first cold liquid joint 1251 and the first hot liquid joint 1261 can also be elbows with a lateral docking portion.

[0086] Similarly, please refer to Figure 1 that, in some embodiments, in order to reduce the occupation of space, the third cold liquid joint 1253 communicating with the third cold liquid pipeline 1131 and the third hot liquid joint 1263 communicating with the third hot liquid pipeline 1132 can also be elbows with a lateral docking portion, so that the third cold liquid pipeline 1131 and the third hot liquid pipeline 1132 form a tendency to extend in the horizontal direction starting from the third cold liquid joint 1253 and the third hot liquid joint 1263. Of course, in some other embodiments, the third cooling head 113 is directly provided above the third cold liquid joint 1253 and the third hot liquid joint 1263. At this time, the third cold liquid joint 1253 and the third hot liquid joint 1263 can also be straight heads facing upward.

[0087] In addition, please refer to Figures 7 - 9 that, in some embodiments, each joint (including but not limited to the illustrated first cold liquid joint 1251, first hot liquid joint 1261, second cold liquid joint 1252, second hot liquid joint 1262, third cold liquid joint 1253 and third hot liquid joint 1263) can be directly provided on the top surface of each corresponding collecting end (including but not limited to the illustrated first cold liquid collecting end 1221, first hot liquid collecting end 1231, second hot liquid collecting end 1232 and second cold liquid collecting end) to facilitate better connection of the pipelines. Of course, please refer to Figure 10 that, in some other embodiments, each joint (including but not limited to the illustrated first cold liquid joint 1251, first hot liquid joint 1261, second cold liquid joint 1252, second hot liquid joint 1262, third cold liquid joint 1253 and third hot liquid joint 1263) can be directly provided on the side surface of each corresponding collecting end (including but not limited to the illustrated first cold liquid collecting end 1221, first hot liquid collecting end 1231, second hot liquid collecting end 1232 and second cold liquid collecting end), such as being provided on the first side surface A perpendicular to the first direction and the second side surface B parallel to the first direction.

[0088] In some embodiments, both the first board 211 and the second board 212 are GPU control boards, and the third board 213 is a CPU control board. In other embodiments, any two of the first board 211, the second board 212, and the third board 213 can be GPU control boards, and the other one can be a CPU control board. Of course, alternatively, any two of the first board 211, the second board 212, and the third board 213 can be CPU control boards, and the other one can be a GPU control board. Or, all of the first board 211, the second board 212, and the third board 213 can be CPU control boards or GPU control boards.

[0089] Further, when there are multiple cooling heads 110, for example, there are at least two cooling heads 110, the connection modes between the cooling heads 110 can be in series or in parallel at this time. Among them, the series and parallel refer to the series or parallel connection of the coolant circulation pipelines corresponding to the cooling heads 110.

[0090] Specifically, please refer to Figure 11 , in some embodiments, there are three cooling heads 110 (including but not limited to the illustrated first cooling head 111, second cooling head 112, and third cooling head 113), and the coolant circulation pipelines of the first cooling head 111, second cooling head 112, and third cooling head 113 are all connected in parallel to the liquid pipe heat dissipation module 120.

[0091] Please refer to Figure 12 and 13 , in some embodiments, there are three cooling heads 110 (including but not limited to the illustrated first cooling head 111, second cooling head 112, and third cooling head 113). After the coolant circulation pipeline between the first cooling head 111 and the second cooling head 112 is connected in series, it is connected in parallel with the coolant circulation pipeline of the third cooling head 113 to the liquid pipe heat dissipation module 120.

[0092] Please refer to Figure 14 , in some embodiments, there are three cooling heads 110 (including but not limited to the illustrated first cooling head 111, second cooling head 112, and third cooling head 113), and the coolant circulation pipelines between the first cooling head 111, third cooling head 113 and the second cooling head 112 are connected in series in sequence.

[0093] Please refer to Figure 15 , in some embodiments, there are three cooling heads 110 (including but not limited to the illustrated first cooling head 111, second cooling head 112, and third cooling head 113), and the coolant circulation pipelines between the first cooling head 111, second cooling head 112 and the third cooling head 113 are connected in series in sequence.

[0094] In addition, the multiple cooling heads 110 can also be connected through a liquid path in other ways than those shown in the above embodiments, and are not limited to the solutions shown in the above embodiments.

[0095] Further, regarding the position where the driving member 130 is provided, in some embodiments, please refer to Figures 13 - 15 , there are at least two cooling heads 110 (illustrated as three cooling heads 110, including but not limited to the illustrated first cooling head 111, second cooling head 112, and third cooling head 113). Each cooling head 110 is connected to the corresponding cold liquid joint 125 and hot liquid joint 126 through a circulation pipeline to form a coolant circulation liquid path (the coolant circulation liquid paths of the cooling heads 110 can be either in parallel or in series, which has been described in detail above). Among them, a driving member 130 is provided in at least a part of the coolant circulation liquid paths where the cooling heads 110 are located.

[0096] For example, in Figures 13 - 15 the illustrated embodiment, driving members 130 (such as water pumps) are respectively provided in the coolant circulation liquid paths of the first cooling head 111 and the second cooling head 112, while no driving member 130 is provided in the coolant circulation liquid path corresponding to the third cooling head 113. Since the coolant circulation liquid paths of the cooling heads 110 are finally in a connected state through the heat dissipation liquid pipe 121, the coolant in the coolant circulation liquid path of the third cooling head 113 can flow by relying on the driving force generated by the driving members 130 in the coolant circulation liquid paths of the first cooling head 111 and the second cooling head 112. This structure can further simplify the structure of the entire liquid cooling device 100 and reduce costs.

[0097] In particular, when the liquid cooling device 100 is applied to cool the CPU control board and GPU control board of an ultrasonic device, since the heat generation of the GPU control board is higher than that of the CPU control board, therefore, driving members 130 can be added in the coolant circulation liquid paths corresponding to the cooling heads 110 (such as the first cooling head 111 and the second cooling head 112) for cooling the GPU control board to increase the flow rate of the coolant in these cooling heads 110, while the driving members 130 can be omitted in the coolant circulation liquid paths corresponding to the cooling heads 110 (such as the third cooling head 113) for cooling the CPU control board to simplify the structure and reduce costs.

[0098] Of course, in some embodiments, driving members 130 can also be provided in the coolant circulation liquid paths of each cooling head 110 to drive the coolant.

[0099] In some embodiments, the driving member 130 can be provided at any position in the coolant circulation liquid path of the cooling head 110. Please refer to Figures 13 - 15 , in some embodiments, the driving member 130 is integrated in the corresponding cooling head 110.

[0100] In addition, please refer to Figure 11 and 12 , in some embodiments, in the coolant circulation liquid path of at least one cooling head 110, the driving member 130 is disposed in the corresponding cold liquid collecting end 122 or the hot liquid collecting end 123. When the driving member 130 is disposed in the corresponding cold liquid collecting end 122 or the hot liquid collecting end 123, since the circulation pipelines of each cooling head 110 converge at the cold liquid collecting end 122 or the hot liquid collecting end 123, at this time, a driving member 130 can drive the circulation pipelines of multiple cooling heads 110, thereby reducing the number of driving members 130, further simplifying the structure and reducing the cost.

[0101] Furthermore, please refer to Figures 11 - 12 , in some embodiments, when the liquid cooling device 100 operates for a long time, the coolant in the entire liquid cooling device 100 will dissipate. Therefore, in this embodiment, the cooling head 110 is higher than its corresponding cold liquid collecting end 122 and hot liquid collecting end 123. At this time, the driving member 130 is disposed in the corresponding cold liquid collecting end 122 or the hot liquid collecting end 123. Under the action of gravity, the coolant can preferentially flow into the driving member 130, ensuring that there is always coolant in the driving member 130 even if the coolant dissipates, and avoiding the driving member 130 from idling.

[0102] Of course, in some other embodiments, the driving member 130 can also be disposed on the cooling head 110. For example, at least one cooling head 110 and the driving member 130 are of an integrated structure. At this time, since the cooling head 110 is usually at a relatively high position, when the liquid cooling device 100 operates for a long time, the coolant in the entire liquid cooling device 100 will dissipate, most likely resulting in the lack of coolant in the driving member 130 and idling, and then causing poor heat dissipation. In this regard, in some embodiments, the integrated structure includes a pump body and a driving structure. The pump body has a pump chamber for accommodating the coolant, and the pump chamber is communicated with the circulation pipeline. The driving structure is disposed in the pump chamber to drive the coolant to flow; at least a part of the outer wall of the pump body is a cooling surface for contacting the corresponding board. In this embodiment, it further includes at least one liquid storage. The liquid storage has a liquid storage chamber for storing the coolant. One liquid storage chamber is communicated with at least one pump chamber through a compensation channel to compensate the coolant in the pump chamber when the coolant in the pump chamber is insufficient.

[0103] Please refer to Figure 16 , in some embodiments, at least one cooling head 110 can be respectively provided with a liquid storage 140. As shown in the figure, the first cooling head 111 and the second cooling head 112 are respectively provided with a liquid storage 140.

[0104] Please refer to Figure 17, in some embodiments, a liquid storage 140 can also replenish at least one cooling head 110 at the same time. As shown in the figure, the liquid storage 140 is in communication with the first cooling head 111 and the second cooling head 112 at the same time for liquid replenishment.

[0105] Furthermore, in some embodiments, after the coolant runs for a long time, impurities may accumulate, which may cause the coolant circulation liquid path to be blocked and affect the heat dissipation effect. For this, please refer to Figure 18 , in some embodiments, a filtering device 150 is provided in the coolant circulation liquid path of at least one cooling head 110 for filtering the coolant. The filtering device 150 can adopt any existing liquid filtering device 150.

[0106] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
