Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention.

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the heat dissipation assembly and the electronic device using the heat dissipation assembly of the present invention will be described in detail with reference to the accompanying drawings and embodiments.

Referring to fig. 1 to 3, in a preferred embodiment of the present invention, an electronic device 100 includes a heating element 20 and a liquid-cooled heat dissipation device 30, wherein the liquid-cooled heat dissipation device 30 dissipates heat from the heating element 20.

In one embodiment, the electronic device 100 is a Graphics card, and the heat generating element 20 is a Graphics Processing Unit (GPU).

The liquid-cooled heat sink 30 includes a heat sink assembly 10, a liquid-cooled head 32, and a pump 34. The liquid cooling head 32 can be connected to a pump 34 through a conduit 35, the pump 34 is connected to the heat sink assembly 10 through a conduit 36, and the heat sink assembly 10 is further connected to the liquid cooling head 32 through a conduit 37. In this way, the liquid cooling head 32, the pump 34 and the heat dissipation assembly 10 form a heat dissipation circulation system to dissipate heat for the heating element 20. A thermally conductive liquid (not shown) may flow within these closed conduits.

The liquid cooling head 32 is disposed on the heating element 20, can absorb heat of the heating element 20, and enters the heat dissipation assembly 10 for heat exchange under the action of the heat conducting liquid and the pump. After heat exchange through the heat dissipation assembly 10, the cold liquid is transmitted to the liquid cooling head 32 through the conduit 37 to dissipate heat of the heating element 20.

Referring to fig. 4 and 5, the heat dissipation assembly 10 may further include a centrifugal fan 11 and a heat exchanger 14.

The centrifugal fan 11 has an air outlet 12, and the centrifugal fan 11 is used for sucking air and blowing out from the air outlet 12.

The heat exchanger 14 has an air inlet 15, the air inlet 15 of the heat exchanger 14 is in butt joint with the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 of the centrifugal fan 11 is blown towards the air inlet 15 of the heat exchanger 14.

In a preferred embodiment, the centrifugal fan 11 further has an air inlet 13, and the air inlet 13 is used for sucking air. Further, the centrifugal fan 11 is rotatable along the rotation axis a. When the centrifugal fan 11 rotates along the rotation axis a, the air inlet 13 of the centrifugal fan 11 can suck air in a direction parallel to the rotation axis a to generate an air flow. Wherein the heat exchanger 14 has a rectangular parallelepiped shape.

Further, when the centrifugal fan 11 rotates along the rotation axis a, the air outlet 12 of the centrifugal fan 11 can blow an air flow in an air flow direction perpendicular to the rotation axis a. For example, the air outlet 12 is disposed at a side of the centrifugal fan 11.

Specifically, the centrifugal fan 11 further includes a fan blade (not shown) which can rotate along the rotation axis a, and the fan blade sucks air from the air inlet 13 to generate an air flow, and finally blows the air out from the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 enters the inside of the heat exchanger 14.

When the electronic device 100 is powered on to work, the heating element 20 starts to work and generates a certain amount of heat, the liquid cooling head absorbs the heat of the heating element 20 and exchanges heat with the heat exchanger in the heat dissipation assembly 10, at this time, the air is sucked into the air inlet 13 of the centrifugal fan 11 to generate an air flow, the air flow is blown out from the air outlet 12 of the centrifugal fan 11, and the air flow blown out from the air outlet 12 enters the heat exchanger 14.

Because the air outlet 12 of the centrifugal fan 11 is arranged at the side of the centrifugal fan 11, the heat exchanger 14 and the centrifugal fans 11 with different sizes can be matched to meet the requirement of heat dissipation only by ensuring that the air outlet 12 of the centrifugal fan 11 is matched with the air inlet 15 of the heat exchanger 14.

The liquid-cooled heat dissipation device 30 and the electronic device 100 using the liquid-cooled heat dissipation device 30 can dissipate heat from the heating element 20 by disposing the liquid-cooled head 32 on the heating element 20 and absorbing heat of the heating element 20 to exchange heat with the heat dissipation assembly 10.

Therefore, the electronic device integrated with the liquid cooling heat sink has high heat dissipation efficiency and the same operation convenience as the air cooling electronic device, and the case does not need to consider the compatibility with the liquid cooling heat sink kit.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited. It will be understood by those skilled in the art that various modifications and equivalent arrangements can be made without departing from the spirit and scope of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
