Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As an embodiment of the present invention, this embodiment provides a heat dissipation device, refer to fig. 1, do the utility model discloses a heat dissipation device's schematic structure diagram, include: the device comprises a heat absorption end 1, an electromagnetic pump 2, a connecting pipeline 3, a water cooling system 4 and a heat exchange medium 5. Wherein,
the connecting pipeline 3 has heat conductivity, the connecting pipeline 3 penetrates through the heat absorption end 1, meanwhile, the middle section of the connecting pipeline is embedded into the water cooling system 4, and two ports of the connecting pipeline 3 are respectively connected with the input end and the output end of the electromagnetic pump 2; the heat absorption end 1 is close to a target heat source, and the heat exchange medium 5 is sealed in a sealed circulation flow channel formed by the connecting pipeline 3 and the electromagnetic pump 2 and can circularly flow along the sealed circulation flow channel under the driving of the electromagnetic pump 2.
It is understood that the heat dissipating apparatus of the present embodiment includes the electromagnetic pump 2 and the connecting pipe 3 constituting the sealed circulation flow passage, and the heat absorbing end 1 as the heat absorbing structure and the water cooling system 4 as the heat dissipating end, and also includes the heat exchange medium 5 capable of circulating in the sealed circulation flow passage to transport heat. The connecting pipe 3 is used not only for providing a flow line for the heat exchange medium 5, but also for transferring heat in the heat exchange medium 5 to the water cooling system 4 as a medium.
The heat absorbing end 1, which is a heat absorbing structure of the heat sink, is disposed near a target heat source at the time of application or embedded inside the target heat source. Two ports of the connecting pipeline 3 are respectively connected with the input end and the output end of the electromagnetic pump 2, the connecting pipeline 3 and the electromagnetic pump 2 form a circulating flow channel, namely a sealed circulating flow channel, of a heat exchange medium 5, and the sealed circulating flow channel is filled with the heat exchange medium 5.
In order to facilitate the removal of heat absorbed by the target heat source at the heat absorption end 1, a connecting pipe 3 is provided through the heat absorption end 1. Considering that the heat exchange medium 5 needs to dissipate the heat away from the heat absorbing end 1 after taking away the heat from the heat absorbing end 1 along the connecting pipeline 3, a section of structure provided with the connecting pipeline 3 is embedded into the water cooling system 4. The structure of the heat dissipation device formed in this way is as follows: two ends of the connecting pipeline 3 are respectively connected with two ends of the electromagnetic pump 2, one section of the connecting pipeline 3 is embedded in the heat absorption end 1, and the other section of the connecting pipeline 3 is embedded in the water cooling system 4.

In one embodiment, the heat sink 1 is further made of copper, aluminum, nickel, stainless steel, graphite or graphene. In another embodiment, the connecting tube 3 is further made of a heat conducting material, in particular copper, nickel or aluminum.
It can be understood that, considering that the heat absorbing end 1 is used as a main heat absorbing structure, it is required to have a better heat conducting property to dissipate more heat from the target heat source, so as to achieve a better heat dissipating effect. Consider simultaneously that materials such as copper, aluminium, nickel, stainless steel, graphite and graphite all have better heat conductivility, and choose for use one of copper, aluminium, nickel, stainless steel, graphite and graphite to make heat absorption end 1 and be applied to in the embodiment of the utility model provides an in heat abstractor.

Under the drive of the electromagnetic pump 2, the high-temperature liquid metal in the connecting pipeline 3 embedded in the heat absorption end 1 flows into the water cooling system 4 to be cooled by water. The liquid metal cooled by the water cooling system 4 flows into the heat absorption end 1, and the high-temperature liquid metal gallium-indium alloy in the heat absorption end 1 transfers heat to the liquid metal in the connecting pipeline 3 embedded in the heat absorption end 1, so that a cyclic heat absorption-heat dissipation process is formed. The liquid metal is driven by the electromagnetic pump 2 to bring the heat of the heat dissipation end of the air conditioner to the water cooling system 4 for heat dissipation, so that the heat dissipation efficiency is higher, and the heat dissipation effect is faster.
