Wherein the liquid 3 may be water, e.g. the liquid 3 is fresh water. The liquid 3 is compatible with the material of the solid particles 2 chosen and with the material of the circulation line 1 to ensure that no corrosion or other effects occur over a very large temperature range.
The cold end heat exchanger 5 and the hot end heat exchanger 6 are both connected with the circulating pipeline 1.

The circulation pipeline 1 is made of a metal material in order to facilitate heat transfer between the circulation pipeline 1 and the cold-end heat exchanger 5 and the hot-end heat exchanger 6.
Wherein, under the drive of the electromagnetic driver 4, the solid particles 2 move along the extending direction of the circulating pipeline 1, thereby driving the liquid 3 to move along the extending direction of the circulating pipeline 1. That is, the electromagnetic driver 4 provides a driving force for the movement of the solid particles 2 so that the solid particles 2 can move in the extending direction of the circulation line 1.
In the embodiment of the invention, the electromagnetic force provided by the electromagnetic driver 4 drives the solid particles 2 in the solid-liquid mixture to move along the extending direction of the circulating pipeline 1, the solid particles 2 drive the liquid 3 to flow to form flowing circulation, and heat is further taken away from the hot end heat exchanger 6 to the cold end heat exchanger 5 for guiding out.

In the embodiment of the invention, the electromagnetic driver generates a magnetic field, the magnetic field generates a driving force for the solid particles 2 along the axial direction of the fluid pipeline 41, the liquid 3 also moves along with the solid particles 2 under the driving of the solid particles 2, so that the liquid moves in the circulating pipeline 1, when the magnetic field force acts on the solid particles 2 sufficiently, the solid-liquid two-phase flow in the circulating pipeline 1 generates circulating flow, and when the solid-liquid two-phase flow flows through the hot-end heat exchanger 6, the heat is absorbed, the heat is brought to the cold-end heat exchanger 5, the heat is released, and the energy transfer is completed repeatedly.
The pipe sections of the fluid pipe 41 and the circulation pipe 1 are not limited to round pipes, but may be square pipes, ellipses, and the like, and the whole pipe sections may be straight pipes or bent pipes, and are not particularly limited herein.
In an alternative embodiment, the electromagnetic driver 4 further comprises a power supply, a switching unit and a controller.
The controller sends a control signal to the switching unit for adjusting the magnitude of the current supplied to the coil 42 by the power supply.
The magnitude of the current of the coil 42 is adjusted according to the power demand for heat exchange, so that the power for heat exchange is adjusted for increasing or decreasing the operation speed of the solid-liquid mixture.
The greater the current of the coil 42, the greater the operation speed of the solid-liquid mixture, and the smaller the current of the coil 42, the lower the operation speed of the solid-liquid mixture.

The core 21 may be made of a material that is easily controlled by a magnetic field, such as iron, and the case 22 may be made of a polymer, such as tetrafluoroethylene or polytetrafluoroethylene.
The core 21 at the center occupies a smaller proportion, and the shell 22 at the outer side of the core 21 occupies a larger proportion of volume, so that the overall density of the solid particles 2 is close to that of the liquid 3. While the surface of the solid particles 2 is not in a smooth form to effectively drive the flow of the liquid 3.
It can be appreciated that the polymer material such as polytetrafluoroethylene is used for the outer surface of the core 21, and has a low friction coefficient, so that the blockage of the solid particles 2 can be effectively avoided, and the running of the liquid 3 can be effectively ensured.
That is, the content of the solid particles 2 in the solid-liquid mixture is adjusted by the solid particle replenishment tank 8, or the solid particles 2 having the larger cores 21 are replaced, according to the power supply voltage or current limit, other electromagnetic limit.
