[0001] The present invention relates to the field of reactor technology, and in particular to an electromagnetic pump heat dissipation device and a reactor system. Background Art

[0002] The development of lead-cooled fast reactors is one of the main routes for the fourth-generation nuclear energy system. The lead-cooled fast reactor system has a simple and compact structure, high fuel utilization, and good thermal parameters. The key power components of the lead-cooled fast reactor system use electromagnetic pumps, which can effectively solve the risk of power loss or partial loss due to corrosion and abrasion of power components, reducing major hidden dangers to the safe operation of the reactor.

[0003] However, the normal operation of the electromagnetic pump under high temperature conditions becomes particularly important. The operating temperature range of high-temperature lead-bismuth is generally 500℃-900℃, and the maximum temperature that the electromagnetic pump winding can withstand is generally below 400℃. Therefore, the electromagnetic pump heat dissipation device has become one of the core issues in the research and development of electromagnetic pumps.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] Please refer to the following Figures 1 to 5 An electromagnetic pump heat sink and a reactor system according to an embodiment of the present invention are described.

[0032] like Figures 1 to 5 As shown, the electromagnetic pump heat dissipation device of the embodiment of the present invention comprises: a pipeline 1, an electromagnetic pump 2, a power generation module 3 and a radiator 4. The pipeline 1 has a fluid cavity 11, and liquid metal is arranged in the fluid cavity 11. The electromagnetic pump 2 comprises an outer iron core 21 and a plurality of windings 22. The plurality of windings 22 are sleeved outside the pipeline 1 and arranged in sequence along the axial direction of the pipeline 1. The outer iron core 21 is arranged on the outer side of the pipeline 1 along the radial direction of the pipeline 1, and the windings 22 are passed through the outer iron core 21.

[0033] The power generation module 3 includes a sleeve 31 and a magnet 32, and the magnet 32 ​​is a permanent magnet 32. The sleeve 31 is installed on the pipeline 1 and communicated with the fluid chamber 11. The sleeve 31 has two conductive plates 311, which are arranged oppositely along the first direction, and the conductive plates 311 are insulated and connected to the pipeline 1. There are at least two groups of magnets 32 and they are arranged on opposite sides of the sleeve 31 along the second direction. The magnetic poles of the two groups of magnets 32 facing one end of the sleeve 31 are opposite, that is, one group of magnets 32 facing one end of the sleeve 31 is the S pole, and the other group of magnets 32 facing one end of the sleeve 31 is the N pole. The first direction and the second direction are both orthogonal to the axial direction of the sleeve 31, and there is an angle between the first direction and the second direction. The positive and negative poles of the radiator 4 are respectively connected to the two conductive plates 311, and the radiator 4 is arranged adjacent to the electromagnetic pump 2 to dissipate heat for the electromagnetic pump 2.

[0034] According to the electromagnetic pump heat dissipation device of the embodiment of the present invention, when the electromagnetic pump heat dissipation device is working, multiple windings 22 are energized to generate a magnetic field to push the liquid metal in the pipeline 1 to flow along the axial direction of the pipeline 1. When the liquid metal passes through the two conductive plates 311 in the sleeve 31, since there are at least two groups of magnets 32 and they are arranged on opposite sides of the sleeve 31 along the axial direction orthogonal to the pipeline 1, the flowing liquid metal can cut the magnetic flux lines generated by the magnets 32. Since there is an angle between the first direction and the second direction, that is, there is an angle between the arrangement direction of the two groups of magnets 32 and the arrangement direction of the two conductive plates 311, the free charges in the liquid metal can be directed to move under the action of the induced electric field to form a current, so that a potential difference is generated on the two conductive plates 311. Since the positive and negative poles of the radiator 4 are respectively connected to the two conductive plates 311, the radiator 4 can be powered by the current generated by the power generation module 3 to dissipate heat for the electromagnetic pump 2. Therefore, the electromagnetic pump heat dissipation device of the embodiment of the present invention does not need to rely on an external power supply, and can be powered by the self-sustaining output of the electromagnetic pump heat dissipation device to continuously dissipate heat for the electromagnetic pump 2, which is beneficial to the long-term stable operation of the electromagnetic pump 2 and has higher economic benefits.

[0035] It can be understood that the power generation module 3 of the electromagnetic pump heat dissipation device of the embodiment of the present invention utilizes the principle that metal cuts magnetic flux lines to generate current. Liquid metal can flow in the sleeve 31 to cut the magnetic flux lines generated by the two magnets 32, so that the two conductive plates 311 can generate current, thereby supplying power to the radiator 4.

[0036] For example, the radiator 4 may be a cooling fan or a refrigerator. Of course, the radiator 4 may also be other devices that can reduce the temperature of the electromagnetic pump 2. The present application does not specifically limit the type and structure of the radiator 4.

[0037] In some embodiments, the axial direction of the sleeve 31 is on the same straight line as the axial direction of the pipe 1, so that the liquid metal in the pipe 1 can be directly passed into the sleeve 31. The first direction, the second direction and the axial direction of the pipe 1 are orthogonal to each other. In other words, the two conductive plates 311 are arranged relative to each other along the first direction, and the two sets of magnets 32 are arranged relative to each other along the second direction. The first direction, the second direction and the axial direction of the pipe 1 are perpendicular to each other. It can be understood that the outer sides of the two conductive plates 311 are respectively provided with leads (such as Figure 1 The two leads A and B in the conductive plate 311 can be connected to the positive and negative electrodes of the heat sink 4, respectively. Since the outer side of the conductive plate 311 is provided with leads, in order to avoid the leads, the arrangement direction (second direction) of the magnet 32 ​​can be orthogonal to the arrangement direction (first direction) of the conductive plate 311, thereby making the potential difference generated by the two conductive plates 311 larger, the power generation efficiency higher, and making the structure of the power generation module 3 more compact, which is more conducive to the miniaturization design of the power generation module 3.

[0038] Alternatively, if Figure 2 and Figure 3 As shown, the sleeve 31 further includes two insulating plates 312, which are arranged opposite to each other along the second direction, and the two insulating plates 312 are connected to the two conductive plates 311 to form a rectangular cavity 313, and the cavity 313 is connected to the fluid cavity 11. The power generation module 3 further includes an insulating pad 33, which is arranged between the sleeve 31 and the pipeline 1 along the axial direction of the sleeve 31. It can be understood that the pipeline 1 is usually made of conductive material. In order to avoid the problem of short circuit between the two conductive plates 311, the two conductive plates 311 can be separated by the insulating plates 312 along the circumference of the sleeve 31, and the two conductive plates 311 can be separated by the insulating pads 33 along the axial direction of the sleeve 31, thereby ensuring that a stable potential difference is formed between the two conductive plates 311.

[0039] Optionally, there are at least two power generation modules 3, which are respectively arranged at both ends of the electromagnetic pump 2 along the axial direction of the electromagnetic pump 2 and connected to the pipeline 1. It can be understood that the two power generation modules 3 can supply power to the radiator 4 at the same time to improve the power generation efficiency of the power generation modules 3. And when one of the power generation modules 3 is damaged, the other power generation module 3 can continue to generate electricity, thereby improving the stability of the heat dissipation of the electromagnetic pump 2.

[0040] The number of power generation modules 3 can be selected according to the actual power of the electromagnetic pump 2. For example, when the power of the electromagnetic pump 2 is relatively large, a larger number of power generation modules 3 can be arranged, and the sleeves 31 of the multiple power generation modules 3 can be arranged at intervals along the axial direction of the pipeline 1. For example, the sleeves 31 of the multiple power generation modules 3 can be arranged on the pipeline 1 on both sides of the axial direction of the electromagnetic pump 2 to ensure that the winding 22 can be maintained at a normal working temperature.

[0041] In order to facilitate installation and removal of the power generation module 3, the magnet 32 ​​can be installed on the sleeve 31, and the sleeve 31 is coaxially and detachably connected to the pipeline 1. For example, the sleeve 31 and the pipeline 1 can be connected by means of a sealing flange.

[0042] In one example, there are two radiators 4, the two radiators 4 are respectively connected to the two power generation modules 3, and the radiators 4 are arranged at the ends of the electromagnetic pump 2 along the axial direction of the electromagnetic pump 2. That is, when one of the radiators 4 fails, the other radiator 4 can also work normally to ensure the reliability of heat dissipation of the electromagnetic pump 2. In addition, since the two radiators 4 are respectively arranged at the ends of the electromagnetic pump 2 in the axial direction, and the radiators 4 dissipate heat in the direction of the electromagnetic pump 2, the heat dissipation effect of the electromagnetic pump 2 can be improved.

[0043] In other examples, there are three or more radiators 4 , which are sleeved outside the electromagnetic pump 2 and arranged at intervals along the axial direction of the electromagnetic pump 2 to fully dissipate heat for the winding 22 of the electromagnetic pump 2 .

[0044] In some embodiments, Figure 4 As shown, the power generation module 3 also includes an energy storage module 34, the positive and negative electrodes of the energy storage module 34 are electrically connected to the two conductive plates 311 respectively, and the positive and negative electrodes of the radiator 4 are electrically connected to the positive and negative electrodes of the energy storage module 34 respectively. The energy storage module 34 is used to store the electric energy generated by the two conductive plates 311 and can supply power to the radiator 4. It can be understood that the power generation module 3 can transfer excess electric energy to the energy storage module 34, and when the hydraulic metal stops flowing, the radiator 4 can be supplied with power through the energy storage module 34, so that the radiator 4 can still be supplied with power through the energy storage module 34 for a period of time after the electromagnetic pump 2 stops working, so as to further dissipate the heat of the electromagnetic pump 2, so as to improve the heat dissipation effect of the electromagnetic pump 2.

[0045] Alternatively, if Figure 4 As shown, the power generation module 3 also includes a controller 35 and a temperature sensor (not shown). The temperature sensor is arranged on the outer core 21 or the winding 22. The controller 35 is electrically connected to the temperature sensor and the radiator 4. The controller 35 is used to automatically adjust the heat dissipation power of the radiator 4 according to the temperature of the temperature sensor. For example, the controller 35 can be a PID controller 35. There can be multiple temperature sensors, and the multiple temperature sensors are arranged at intervals along the axial direction of the winding 22 to detect the temperature of the winding 22 at different positions. When the temperature of the winding 22 detected by a certain temperature sensor is greater than the set value, the heat dissipation power of the radiator 4 can be increased by the controller 35. When the temperature of the winding 22 detected by the temperature sensor is less than the set value, the heat dissipation power of the radiator 4 can be reduced by the controller 35. In this way, the intelligent control effect of the electromagnetic pump heat dissipation device can be improved.

[0046] In other examples, the power generation module 3 further includes a rheostat 36 , which is connected in series to the circuit of the radiator 4 . An operator can manually manipulate the resistance of the rheostat 36 to adjust the heat dissipation power of the radiator 4 .

[0047] In some embodiments, the electromagnetic pump heat dissipation device further includes a heat insulation layer (not shown), which is disposed on the wall surface of the pipeline 1. This can reduce the heat transferred from the liquid metal to the outer core 21 and the winding 22, thereby lowering the temperature of the outer core 21 and the winding 22.

[0048] Furthermore, the outer core 21 has a heat dissipation fin (not shown) on one side facing away from the pipe 1, and the heat dissipation fin is arranged along the axial direction of the pipe 1. That is, a plurality of heat dissipation fins extending vertically are arranged along the entire length direction of the outer core 21, thereby significantly increasing the heat dissipation area of ​​the outer core 21 and significantly improving the spatial conditions of natural convection heat exchange, so as to further reduce the temperature of the electromagnetic pump 2.

[0049] Specifically, Figure 1 and Figure 5 As shown, the electromagnetic pump 2 further includes an inner iron core 23 and an outer shell 24, wherein the inner iron core 23 is disposed in the pipe 1 and is arranged radially opposite to the outer iron core 21. The outer shell 24 is sleeved outside the pipe 1 and defines an installation cavity with the outer wall of the pipe 1, wherein the winding 22, the outer iron core 21 and the radiator 4 can all be disposed in the installation cavity, whereby the outer shell 24 can protect the winding 22, the outer iron core 21 and the radiator 4 to avoid the problem of the winding 22, the outer iron core 21 and the radiator 4 being bumped, which is beneficial to prolonging the service life of the electromagnetic pump heat dissipation device.

[0050] A reactor system according to another embodiment of the present invention includes the electromagnetic pump heat dissipation device of the present invention.

[0051] According to the reactor system of the embodiment of the present invention, when the electromagnetic pump heat dissipation device is working, the multiple windings 22 are energized to generate a magnetic field to push the liquid metal in the pipeline 1 to flow along the axial direction of the pipeline 1. When the liquid metal passes through the two conductive plates 311 in the sleeve 31, since there are at least two groups of magnets 32 and they are arranged on opposite sides of the sleeve 31 along the axial direction orthogonal to the pipeline 1, the flowing liquid metal can cut the magnetic flux lines generated by the magnets 32. Since there is an angle between the first direction and the second direction, that is, there is an angle between the arrangement direction of the two groups of magnets 32 and the arrangement direction of the two conductive plates 311, the free charges in the liquid metal can be directed to move under the action of the induced electric field to form a current, so that a potential difference is generated on the two conductive plates 311. Since the positive and negative poles of the radiator 4 are respectively connected to the two conductive plates 311, the radiator 4 can be powered by the current generated by the power generation module 3 to dissipate heat for the electromagnetic pump 2. Therefore, the electromagnetic pump heat dissipation device of the reactor system of the embodiment of the present invention does not need to rely on an external power supply, and can be powered by the self-sustaining output of the electromagnetic pump heat dissipation device to continuously dissipate heat for the electromagnetic pump 2, which is beneficial to the long-term stable operation of the electromagnetic pump 2 and has higher economic benefits.
