[0027] Please refer to Figures 1-3 The present embodiment provides a heat dissipation device 1, the heat dissipation device 1 includes pipe 11 and adjusting assembly 12. Pipe 11 has a containing space 111 for containing cooling liquid; adjusting assembly 12 includes controller 121, driving assembly 122, telescopic assembly 123 and sliding block 124, the controller 121 is electrically connected to the driving assembly 122, the driving assembly 122 includes at least one driving unit, the telescopic assembly 123 includes at least one telescopic unit, the driving unit is rotatably connected to the telescopic unit, the telescopic unit is rotatably connected to the sliding block 124, the telescopic unit and the sliding block 124 are movably arranged in the containing space 111.

[0028] In other words, the driving assembly 122 is connected to the telescopic assembly 123, the telescopic assembly 123 is connected to the sliding block 124, the controller 121 is used for controlling the driving assembly 122, and the driving assembly 122 drives the sliding block 124 to reciprocate relative to the accommodating space 111 through the telescopic assembly 123, so as to change the flow area of the cooling liquid placed in the accommodating space 111.

[0029] The heat dissipation device 1 provided by the embodiment can be applied to charging equipment, processing equipment, electronic equipment, communication equipment, etc., and the embodiment is not limited in this aspect.

[0030] The pipeline 11 has an accommodating space 111, and has a liquid inlet 113 and a liquid outlet 112 which are connected to the accommodating space 111. The cooling liquid flows into the accommodating space 111 from the liquid inlet 113, flows in the accommodating space 111, and then flows out of the pipeline 11 from the liquid outlet 112. The cooling liquid can absorb heat and dissipate heat for components. The cooling liquid includes but is not limited to water, ethylene glycol, mineral oil, etc., and the embodiment is not limited in this aspect.

[0031] The adjusting assembly 12 includes a controller 121, a driving assembly 122, a telescopic assembly 123, and a sliding block 124. The controller 121 can receive and identify signals and control the driving assembly 122 according to the signals. The driving assembly 122 can be used as a starting component, and the driving assembly 122 can directly drive the telescopic assembly 123 to extend and retract, or indirectly drive the telescopic assembly 123 to extend and retract through other components. The driving assembly 122 includes but is not limited to electromagnetic switches, motors, air cylinders, etc., and the embodiment is not limited in this aspect. For example, the driving assembly 122 includes electromagnetic valves, connecting rods, springs, etc. The telescopic assembly 123 can extend and retract, for example, the telescopic assembly 123 includes one or more telescopic units.

[0032] Optionally, the telescopic direction of the telescopic assembly 123 is the same as or opposite to the flow direction of the cooling liquid.

As the slider 124 translates in the accommodating space 111, the position of the slider 124 in the flow changes, thereby changing the flow distribution of the cooling liquid in the flow, and achieving the effect of controlling different heat dissipation areas. Specifically, when the slider 124 translates to a certain position in the accommodating space 111, the slider 124 occupies part of the space in the accommodating space 111, and the flow of the cooling liquid in this area is blocked, and the heat dissipation capacity of this area is weakened, which is suitable for the environment where the heat dissipation demand of the components in this area under the non-working condition is low.

[0034] In summary, the heat dissipation device 1 provided by the embodiment changes the position of the slider 124 in the accommodating space 111 by using the controller 121, the driving assembly 122, and the telescopic assembly 123, thereby changing the flowable area of the cooling liquid in the flow, and further changing the heat dissipation area and the heat dissipation capacity of the heat dissipation device 1, meeting the various heat dissipation demands of the components in each area under multiple working conditions, achieving precise heat dissipation, reducing the risk of condensation and pipe 11 gas accumulation, and improving the heat dissipation efficiency of the heat dissipation device 1.

Alternatively, the first direction is a vertical direction, and the second direction is a horizontal direction; or, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0044] For example, the driving assembly 122 drives the connecting member 125 to move in the vertical direction, so that the connecting member 125 drives the telescopic assembly 123 to telescope in the horizontal direction, so that the telescopic assembly 123 drives the sliding block 124 to slide in the horizontal direction, so as to change the position of the sliding block 124 in the accommodating space 111.
