[0045] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the left and right directions mentioned below.

[0046] like Figures 1 to 5As shown, this embodiment provides a liquid-cooled reactor device, including a reactor body 11 , a shell 12 , a liquid inlet pipeline 14 , a liquid outlet pipeline 15 , and a power system 16 .

[0047] The reactor body 11 includes an iron core 111. The shell 12 is sleeved on the iron core 111 and encloses the iron core 111 to form a heat dissipation channel 13. The heat dissipation channel 13 allows water or other coolant to pass through, and uses the coolant to remove the heat generated by the reactor body 11, thereby cooling the reactor body 11. The heat dissipation channel 13 extends along the circumference of the iron core 111 and can remove more heat. The heat dissipation channel 13 has a liquid inlet 131 and a liquid outlet 132, and the liquid inlet 131 and the liquid outlet 132 are respectively located at the two ends of the extension path of the heat dissipation channel 13. The power system 16 can provide power for the flow of the coolant to achieve the circulation of the coolant. The power system 16 has a liquid supply port 162 and a liquid return port 163. The liquid supply port 162 of the power system 16 is connected to the liquid inlet 131 of the heat dissipation channel 13 via the liquid inlet pipeline 14, and the liquid return port 163 of the power system 16 is connected to the liquid outlet 132 of the heat dissipation channel 13 via the liquid outlet pipeline 15, thereby achieving circulation of the coolant. When the temperature of the reactor body 11 is too high, affecting the operation of the reactor body 11, the power system 16 is activated and used to deliver coolant to the heat dissipation channel 13, thereby achieving circulation of the coolant. Heat from the reactor body 11 can be removed by the coolant, thereby quickly cooling the high-temperature reactor body 11 to a safe temperature. The reactor body 11 operates within a reasonable temperature range, achieving efficient operation of the reactor body 11, and ensuring the operating performance of the reactor body 11.

[0048] Furthermore, a first groove 112 is provided on the outer surface of the iron core 111. The shell 12 has a sleeve groove 121, and a second groove 122 is provided on the inner wall of the sleeve groove 121. The inner wall of the first groove 112 and the inner wall of the second groove 122 together enclose a heat dissipation channel 13. Since the iron core 111 is used to install the coil, and the coil is the main heat source, in this embodiment, the first groove 112 is provided on the outer surface of the iron core 111, and the second groove 122 is provided on the shell 12. Compared with the method of only providing grooves on the shell 12 or the iron core 111, not only can the flow rate of the heat dissipation channel 13 be increased, but the heat generated by the heat source can also be more effectively removed, allowing the liquid to quickly remove the heat generated by the coil. After the housing 12 is mounted on the iron core 111, the inner wall of the first groove 112 and the inner wall of the second groove 122 together enclose a heat dissipation channel 13. Coolant from the power system 16 enters the heat dissipation channel 13 through the liquid inlet 131 of the heat dissipation channel 13 and flows along the circumference of the iron core 111. Finally, it flows back to the power system 16 through the liquid outlet 132 of the heat dissipation channel 13, thus achieving coolant circulation. The liquid-cooled reactor device of this embodiment can quickly cool the high-temperature reactor body 11 to a safe temperature, allowing the liquid-cooled reactor device to operate within a reasonable temperature range, ensuring the operating performance of the liquid-cooled reactor device, and ensuring efficient use of the liquid-cooled reactor device.

[0049] Optionally, multiple first grooves 112 are spaced apart from each other from front to back, and multiple second grooves 122 are spaced apart from each other from front to back. The multiple first grooves 112 and the multiple second grooves 122 correspond one to one and form multiple heat dissipation channels 13. The multiple heat dissipation channels 13 are spaced apart from each other from front to back to improve cooling efficiency. Each heat dissipation channel 13 extends along an N-shaped trajectory, increasing the area through which the coolant passes and improving the cooling effect. When the coolant passes through the heat dissipation channel 13, it first flows from bottom to top, then flows horizontally in the left-right direction, and finally flows from top to bottom back to the power system 16.

[0050] In one embodiment, the liquid inlet pipe 14 includes a liquid inlet pipe body 141 and a first diverter joint 142. One end of the liquid inlet pipe body 141 is connected to the liquid supply port 162 of the power system 16, and the other end of the liquid inlet pipe body 141 is connected to the liquid inlet ports 131 of each heat dissipation channel 13 through the first diverter joint 142. The first diverter joint 142 is provided with a fork, so that the coolant in the liquid inlet pipe body 141 can be diverted to each heat dissipation channel 13, reducing the layout of the pipeline.

[0051] In one embodiment, the liquid outlet pipeline 15 includes a liquid outlet pipe body 151 and a second diverter joint 152. One end of the liquid outlet pipe body 151 is connected to the liquid return port 163 of the power system 16, and the other end of the liquid outlet pipe body 151 is connected to the liquid outlet 132 of each heat dissipation channel 13 through the second diverter joint 152. The second diverter joint 152 is bifurcated, so that the coolant from each heat dissipation channel 13 can be converged to the liquid outlet pipe body 151, reducing the layout of the pipeline.

[0052] Furthermore, the power system 16 includes a pump body 161 and a temperature processing module. The power system 16 integrates the temperature processing module and the kinetic energy component of the coolant. The kinetic energy component is the pump body 161, which can control the flow rate of the coolant according to temperature changes.

[0053] A temperature sensor 17 is provided at the liquid outlet pipe 15 and / or the liquid outlet 132. In this embodiment, the temperature sensor 17 is provided at the liquid outlet 132. Specifically, the temperature sensor 17 is installed at the second diversion joint 152 and can detect the temperature at the liquid outlet 132 in real time. The temperature sensor 17 and the pump body 161 are both electrically connected to the temperature processing module.

[0054] The liquid-cooled reactor device of the present application can determine whether the liquid-cooled reactor device exceeds a set safety temperature based on the temperature at the liquid outlet 132. When the temperature at the liquid outlet 132 is higher than the set safety temperature, the power system 16 is started to allow the coolant to circulate rapidly to reduce the temperature of the liquid-cooled reactor device. Specifically, the control process of the liquid-cooled reactor device of the present application is as follows:

[0055] The maximum temperature of the liquid-cooled reactor device is set to T0, the safe temperature of the liquid-cooled reactor device is set to T1, and the minimum temperature of the liquid-cooled reactor device is set to T2.

[0056] When the temperature sensor 17 detects that the temperature at the liquid outlet 132 is ≧T0, the power system 16 receives the signal and starts, and the power system 16 quickly increases the operating speed, so that the coolant flows to the heat dissipation channel 13 faster and quickly takes away the temperature of the reactor body 11.

[0057] When the temperature sensor 17 detects that the temperature at the liquid outlet 132 is ≤ T1, the power system 16 receives a signal, and the power system 16 reduces the operating speed to allow the coolant to slowly flow to the heat dissipation channel 13, so that the temperature of the reactor body 11 can be maintained within a safe temperature range.

[0058] When the temperature sensor 17 detects that the temperature at the liquid outlet 132 is ≤ T2, the power system 16 receives the signal, the power system 16 stops running, and the temperature of the reactor body 11 rises and remains within a safe temperature range.

[0059] Optionally, a plurality of heat dissipation ribs 123 are provided on the outside of the housing 12, and on both the left and right sides of the housing 12. The plurality of heat dissipation ribs 123 are arranged in intervals from front to back. The heat dissipation ribs 123 and the housing 12 are integrally formed from a material with good thermal conductivity. The heat dissipation ribs 123 provide a heat dissipation effect, which can improve the cooling effect of the liquid-cooled reactor device.

[0060] Furthermore, the reactor body 11 further includes a coil provided on the iron core 111. The heat generated by the coil is transferred to the iron core 111, and finally the heat on the iron core 111 is quickly dissipated by the coolant.

[0061] In one embodiment, the liquid-cooled reactor device further includes a support plate 18 and support legs 19 disposed on the support plate 18. The reactor body 11 is mounted on the support plate 18, with the liquid inlet 131 and the liquid outlet 132 both located at the bottom of the housing 12. The support plate 18 and support legs 19 allow the reactor body 11 to be mounted at a certain height, which facilitates heat dissipation from the reactor body 11.

[0062] This embodiment further provides a heat pump unit, comprising the liquid-cooled reactor device of any of the above embodiments.

[0063] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
