The water-cooled heat dissipation module according to the embodiment of the present application will be described in detail below with reference to fig. 1 to 9.

The water-cooling heat dissipation module comprises: a first heat dissipation branch 110 and a second heat dissipation branch 120 communicated with the first heat dissipation branch 110. The first heat dissipation branch 110 is used for guiding the heat dissipation medium to flow at a first spatial position. The second heat dissipation branch 120 is used for guiding the heat dissipation medium to flow at a second spatial position; the first spatial position and the second spatial position are at least partially not overlapped, so that when the water-cooling heat dissipation module is configured to dissipate heat of an electronic device, at least part of a first heat generation component 220 of the electronic device is dissipated through at least the first heat dissipation branch 110, and at least part of a second heat generation component 230 of the electronic device is dissipated through the second heat dissipation branch 120; through the two heat dissipation branches, heat can be dissipated to at least part of the first heat generation assembly 220 and at least part of the second heat generation assembly 230; the working mode of the water-cooling heat dissipation module is increased, and the adaptability of the water-cooling heat dissipation module is improved.

In the embodiment of the present application, the structure of the first heat dissipation branch 110 is not limited. For example, the first heat dissipation branch 110 may include at least two first tubes, and the at least two first tubes contain a heat dissipation medium therein.

In the embodiment of the present application, the structure of the second heat dissipation branch 120 is not limited. For example, the second heat dissipation branch 120 may include at least two second tubes, and the at least two second tubes contain a heat dissipation medium therein.

Here, the implementation manner of the second heat dissipation branch 120 communicating with the first heat dissipation branch 110 is not limited. For example, the second heat dissipation branch 120 directly communicates with the pipe of the first heat dissipation branch 110. For another example, the second heat dissipation branch 120 and the pipe of the first heat dissipation branch 110 may also be communicated through other structures.

Here, the first spatial position and the second spatial position may not overlap at all, or may not overlap only partially.

Here, the structures of the first and second

heat generating components

220 and 230 are not limited. As long as the first and second

heat generating components

220 and 230 generate heat.

In some optional implementation manners of the embodiment of the present application, the water-cooling heat dissipation module may further include: at least one housing 130 and a drive assembly. At least one box 130 is used for accommodating a heat dissipation medium, and the first heat dissipation branch 110 and the second heat dissipation branch 120 are communicated through the box 130; the driving component is disposed on the first heat dissipation branch 110 or the second heat dissipation branch 120, and the driving component is configured to drive the heat dissipation medium to flow among the first heat dissipation branch 110, the box 130, and the second heat dissipation branch 120; through the box 130, more heat dissipation media can flow between the first heat dissipation branch 110 and the second heat dissipation branch 120, so that more heat of a heating component can be taken away, and the heat dissipation performance of the water-cooling heat dissipation module is improved.

In the present embodiment, the number of the cases 130 is not limited. For example, the case 130 may be provided with one. For another example, the case 130 may be provided with two.

In this implementation, the structure of the drive assembly is not limited.

For example, as shown in fig. 3 and 4, the driving assembly may include: a baffle 140 and a drive 150. The flow guide 140 has a first receiving chamber 141, at least two first outlets 142, and at least two first inlets 143; the at least two first outlets 142 are communicated with the box body 130 through a first part of the first radiating branch 110; at least two first inlets 143 are communicated with the case 130 through a second portion of the first radiating branch 110; the driving device 150 is disposed in the first accommodating cavity 141, and the driving device 150 is configured to drive the heat dissipation medium entering from the first inlet 143 to be output to the second portion of the first heat dissipation branch 110 through the first outlet 142, so as to at least realize the flow of the heat dissipation medium between the box 130 and the heat sink 170; the heat dissipation medium can be introduced from the at least two first outlets 142 and be extracted from the at least two first outlets 142 by the flow guide 140 and the driving device 150; the at least two first outlets 142 are capable of being simultaneously communicated with at least two tubes of the first heat dissipation branch 110, and the at least two first outlets 142 are capable of being simultaneously communicated with at least two tubes of the first heat dissipation branch 110; the quantity of the leading-in pipe bodies and the leading-out pipe bodies is greatly increased; the working mode of the water-cooling heat dissipation module is increased.

In this example, the structure of the driving device 150 is not limited. For example, the driving device 150 may be a pump. Of course, the drive assembly may also comprise only the drive means 150, where the drive assembly has one inlet and one outlet.

In this example, the drive means 150 has a second outlet and a second inlet; flow guide 140 has at least two first outlets 142 and at least two first inlets 143; by providing the driving means 150 in the first receiving chamber 141, the guide member 140 can increase the number of inlets and outlets of the driving assembly.

Here, the sectional area of the at least two first outlets 142 may be greater than that of the second outlets, and the sectional area of the at least two first inlets 143 may be greater than that of the second inlets; so that the cross-sectional area of the drive assembly inlet and outlet can also be increased by the baffle 140; under the condition that the power of the driving device 150 is the same, the flow speed of the heat-dissipating medium can be reduced through the large-area inlet and outlet, so that the heat-dissipating medium can perform heat exchange more fully, and the heat-dissipating capacity of the water-cooling heat-dissipating module can be improved under the condition that the power of the driving device 150 is not changed; in addition, under the condition that the same heat dissipation capacity needs to be provided, the driving device 150 can reduce the input power, so that the noise generated when the water cooling heat dissipation module driving device 150 works at high power can also be reduced.

In this example, as shown in fig. 4 and 6, the driving assembly may further include: a sealing member 161, wherein the sealing member 161 is used for sealing the first side of the driving device 150 into the first accommodating cavity 141 of the guide member 140; to prevent the heat-dissipating medium from flowing out of the first side of the driving device 150; here, the first side of the driving device 150 may be a side where the rotational axis of the driving device 150 is located.

In this example, the structure of the flow guide 140 is not limited. For example, the material of the flow guiding element 140 may be aluminum or copper. The first heat dissipation branch 110 can also dissipate heat of the first heat generating component 220 based on the guiding element 140. For example, as shown in fig. 5 and 6, the driving assembly may further include: the first heat conduction member 162 is attached to one side of the air guiding member 140, and the first heat conduction member 162 is used for contacting with the first heat generating assembly 220, so that the first heat dissipation branch 110 dissipates heat based on the first heat conduction member 162 and the air guiding member 140 in the driving assembly. Of course, the driving assembly may not be provided with the first heat conduction member 162, and the air guide member 140 may be directly contacted with the first heat generating assembly 220. Here, since the first receiving cavity 141 receives a large amount of heat dissipation medium therein, the heat dissipation capability of the first heat dissipation branch 110 can be improved by the contact between the flow guiding member 140 receiving a large amount of heat dissipation medium and the first heat generating component 220.

In this implementation manner, the water-cooling heat dissipation module may further include a heat sink 170, where the heat sink 170 has a plurality of heat dissipation pipes; the plurality of heat dissipation pipes form the first heat dissipation branch 110. Here, the case 130 may be provided with one, and the plurality of radiating pipes communicate with the one case 130. Of course, the tank body 130 may be provided in two, and the two tank bodies 130 are communicated with each other through the plurality of radiating pipes.

Here, the driving assembly may be disposed at one side of the heat sink 170. Of course, the driving assembly may also be disposed within the heat sink 170; here, the driving assembly is disposed in the heat sink 170, so that a space for disposing the water-cooling heat dissipation module can be reduced, and thus, a volume of the water-cooling heat dissipation module can be reduced.

As an example, as shown in fig. 7, the plurality of radiating pipes may include: a first partial radiating pipe 171, a second partial radiating pipe 172, a third partial radiating pipe 173 and a fourth partial radiating pipe 174. The first end of the first partial radiating pipe 171 is communicated with the box body 130; the second partial radiating pipe 172 is spaced apart from the first partial radiating pipe 171 in the first direction, a first end of the second partial radiating pipe 172 is communicated with the tank body 130, and a second end of the second partial radiating pipe 172 is communicated with a second end of the first partial radiating pipe 171; the first end of the third partial radiating pipe 173 is communicated with the tank body 130, and the second end of the third partial radiating pipe 173 is communicated with the driving assembly; a first end of the fourth partial radiating pipe 174 is communicated with the driving assembly, and a second end of the fourth partial radiating pipe 174 is respectively communicated with a second end of the second partial radiating pipe 172 and a second end of the first partial radiating pipe 171; wherein, the driving unit is disposed in the receiving space defined by the first portion of heat dissipation tube 171, the second portion of heat dissipation tube 172, the third portion of heat dissipation tube 173 and the fourth portion of heat dissipation tube 174.

Here, the first direction is not limited. For example, the first direction may be a width direction of the first partial heat pipe 171.

Here, one of the third and fourth

partial heat pipes

173 and 174 is communicated with the inlet of the driving unit, and the other is communicated with the outlet of the driving unit. As an example, the third radiating pipe 173 is correspondingly communicated with at least two first outlets 142, and the fourth radiating pipe 174 is correspondingly communicated with at least two first inlets 143.

Here, the second ends of the first and second partial radiating

pipes

171, 172 and 174 may be communicated through a pipe body, or through the case 130.

In some optional implementations of the embodiment of the present application, as shown in fig. 8 and 9, the second heat dissipation branch 120 may include: two first partial tubes 121 and two second partial tubes 122. The two first partial pipe bodies 121 are communicated with the box body 130, and the two first partial pipe bodies 121 are used for guiding a heat dissipation medium out of or into the box body; the second partial tube 122 is communicated with the two first partial tubes 121, and the second partial tube 122 is used for absorbing at least part of heat in the second heat generating component 230; wherein the first partial tube 121 and the second partial tube 122 are made of different materials; so as to improve the heat dissipation capability of the second heat dissipation branch 120.

In this implementation, the material of the first partial pipe 121 may be a material with a low thermal conductivity. As an example, the material of the first partial pipe 121 may be rubber.

In this implementation, the material of the second partial pipe 122 may be a material with high thermal conductivity. As an example, the material of the second portion of the tube 122 may be copper or aluminum.

In this implementation, the second partial tube 122 may directly contact the second heat generating component 230, or may contact the second heat generating component 230 through another structure.

As an example, as shown in fig. 8 and 9, the second heat dissipation branch 120 may include: the second partial pipe body 122 is arranged in the second heat conducting member 123 in a penetrating manner, and the second heat conducting member 123 is in contact with the second heating component 230; the area of the second heat-conducting member 123 is larger than that of the second partial pipe 122, so that more heat of the second heat-generating component 230 can be absorbed by the larger area of the second heat-conducting member 123.

Here, the second heat conduction member 123 may have a plate-shaped structure, and may have a block-shaped structure.

Here, the material of the second heat conduction member 123 may be aluminum or copper.
