[0040] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] like Figure 1 and Figure 2 As shown, according to an embodiment of the present disclosure, a micro-arc oxidation electrolyte cooling device is proposed, including: a first trough body 110; a second trough body 120, which is arranged in the first trough body 110, and a first liquid storage space 1101 is formed between the first trough body 110 and the second trough body 120, and a second liquid storage space 1201 is formed in the second trough body 120, the first liquid storage space 1101 is used to contain cooling liquid, and the second liquid storage space 1201 is used to contain electrolyte; wherein the second trough body 120 is made of metal material.

[0042] The micro-arc oxidation electrolyte cooling device provided by the embodiment of the present disclosure includes a first trough body 110 and a second trough body 120, wherein the second trough body 120 is arranged in the first trough body 110, and a first liquid storage space 1101 for accommodating a cooling liquid is formed between the first trough body 110 and the second trough body 120, and the second trough body 120 is formed with a second liquid storage space 1201 for accommodating an electrolyte, and the second trough body 120 is made of a metal material, so that based on the above-mentioned configuration, the micro-arc oxidation electrolyte cooling device provided by the embodiment of the present disclosure can be The second trough body 120 is utilized to provide a heat exchange path for the coolant and the electrolyte, so that the coolant absorbs the heat of the electrolyte through the second trough body 120, thereby realizing cooling of the electrolyte; on the other hand, during the cooling process, the electrolyte can be prevented from contacting the first trough body 110, thereby maintaining the cleanliness of the first trough body 110, and the micro-arc oxidation electrolyte cooling device can have a lower cleaning cost; on another hand, the relative position between the first trough body 110 and the second trough body 120 does not need to be adjusted, thereby helping to reduce the operational difficulty of the electrolyte cooling operation.

[0043] It should be noted that when corrosion-resistant coils are used to cool electrolyte in traditional technology, the outer surface of the corrosion-resistant coils will come into contact with the electrolyte, so after the cooling operation is completed, the surface of the corrosion-resistant coils needs to be cleaned. Due to the limitations of process and materials, the wall thickness of the coils is usually thick and the overall weight is large, and the difficulty of transfer and cleaning is relatively high. Compared with the aforementioned traditional technology, the micro-arc oxidation electrolyte cooling device provided in the embodiment of the present disclosure is based on the aforementioned setting. While being able to cool the electrolyte, it has good cleanliness and ease of use, which is conducive to reducing the cost of cooling the electrolyte.

[0044] It is understandable that, in practical applications, the second liquid storage space 1201 can also be used to accommodate micro-arc oxidation equipment, thereby providing a reaction space for the micro-arc oxidation process.

[0045] It is understandable that the aforementioned coolant can be but is not limited to pure water. When the coolant is pure water, the contamination probability of the micro-arc oxidation electrolyte cooling device can be further reduced, thereby saving the cleaning cost of the micro-arc oxidation electrolyte cooling device and the cooling operation cost of the electrolyte.

[0046] It is understandable that by setting the second tank body 120 to be made of metal material, the thermal conductivity of the tank wall of the second tank body 120 can be improved, which is beneficial to improving the heat exchange efficiency between the coolant and the electrolyte, and ensuring the cooling effect on the electrolyte.

[0047] It is understandable that there may be a variety of connection methods between the first tank body 110 and the second tank body 120, which are not limited here; illustratively, the first tank body 110 and the second tank body 120 may be fixedly connected by bolts and sealing gaskets.

[0048] It should be noted that, in order to facilitate the illustration of the internal situation of the second liquid storage space 1201, Figure 2 Part of the groove wall of the first groove body 110 is hidden.

[0049] like Figure 1 As shown, in some examples, the micro-arc oxidation electrolyte cooling device also includes: a refrigeration component 200, having a first liquid inlet end and a first liquid discharge end, the first liquid inlet end and the first liquid discharge end are both connected to the first liquid storage space 1101, and the refrigeration component 200 is used to cool the coolant.

[0050] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a refrigeration component 200, which can absorb the coolant in the first liquid storage space 1101 through the first liquid inlet end to cool the coolant and reduce the temperature of the coolant, and return the refrigerated coolant to the first liquid storage space 1101 through the first liquid discharge end. In the process of cooling the electrolyte, it is beneficial to keep the coolant at a lower temperature so that the coolant can absorb the heat of the electrolyte, thereby providing reliable protection for the cooling effect of the micro-arc oxidation electrolyte cooling device on the electrolyte.

[0051] like Figure 1 As shown, in some examples, the micro-arc oxidation electrolyte cooling device also includes: a drain pipeline 300, a drain port is provided on the bottom wall of the second trough body 120, and the drain pipeline 300 is connected to the second liquid storage space 1201 through the drain port; a drain valve is used to open or close the drain pipeline 300.

[0052] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a drain pipeline 300 and a drain valve, so as to facilitate the discharge and replacement of the electrolyte in the second liquid storage space 1201, which is beneficial to improving the ease of use of the micro-arc oxidation electrolyte cooling device and reducing the difficulty of cleaning the internal space of the second tank body 120.

[0053] In some examples, the middle area of ​​the bottom wall of the second trough body 120 is lower than the edge area of ​​the bottom wall of the second trough body 120 , and the drain port is opened in the middle area of ​​the bottom wall of the second trough body 120 .

[0054] In this technical solution, the position height of the middle area of ​​the bottom wall of the second trough body 120 can be set lower than the position height of the edge area. Accordingly, the aforementioned drain port can be opened in the aforementioned middle area with a lower position height, thereby facilitating more sufficient discharge of the electrolyte in the second liquid storage space 1201 in actual applications, which is beneficial to further reduce the difficulty of cleaning the internal space of the second trough body 120.

[0055] In some examples, the second tank body 120 is made of stainless steel.

[0056] In this technical solution, the second trough body 120 can be made of stainless steel, thereby improving the corrosion resistance and structural strength of the second trough body 120 and reducing the risk of deformation of the second trough body 120; it can be understood that the electrolyte used in micro-arc oxidation is usually alkaline. Based on the above-mentioned settings of this technical solution, the loss of the second trough body 120 during use can be reduced, and the service life of the second trough body 120 can be extended. At the same time, it can ensure that the trough wall of the second trough body 120 has a higher thermal conductivity, which is conducive to ensuring the cooling effect of the electrolyte.

[0057] In some examples, the micro-arc oxidation electrolyte cooling device also includes: a first heat sink fin, which is arranged on the groove wall of the first groove body 110, and the first heat sink fin is located outside the first groove body 110; and / or a second heat sink fin, which is arranged on the groove wall of the second groove body 120, and the second heat sink fin is located in the first liquid storage space 1101.

[0058] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a first heat dissipation fin, so that based on the above-mentioned setting, the heat exchange area between the first trough body 110 and the external environment can be increased, which is beneficial to the heat dissipation of the coolant, thereby improving the cooling effect of the electrolyte.

[0059] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a second heat dissipation fin, so that based on the above-mentioned configuration, the heat exchange area between the second trough body 120 and the coolant can be increased, which is beneficial to improving the cooling effect on the electrolyte.

[0060] It is understandable that the micro-arc oxidation electrolyte cooling device can include a first heat sink and a second heat sink at the same time, so as to further enhance the cooling effect on the electrolyte. The number of the first heat sink and / or the second heat sink can be multiple, and the multiple first heat sinks can be arranged at intervals on the outside of the first tank body 110. Similarly, the multiple second heat sinks can also be built so as not to reach the outside of the second tank body 120.

[0061] It is understandable that the first heat dissipating fins and the first slot body 110 may be an integrated structure; similarly, the second heat dissipating fins and the second slot body 120 may be an integrated structure.

[0062] like Figure 1 and Figure 2 As shown, in some examples, the micro-arc oxidation electrolyte cooling device also includes: a circulating pump 400, having a second liquid inlet end and a second liquid discharge end; a first circulating pipeline 500, one end of the first circulating pipeline 500 is connected to the second liquid storage space 1201, and the other end is connected to the second liquid discharge end, and at least part of the first circulating pipeline 500 is located in the first liquid storage space 1101; a second circulating pipeline 600, one end of the second circulating pipeline 600 is used to be connected to the second liquid storage space 1201, and the other end is connected to the second liquid inlet end.

[0063] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a circulation pump 400, a first circulation pipeline 500 and a second circulation pipeline 600. Based on the above-mentioned arrangement, during the cooling of the electrolyte, the circulation pump 400 may be used to drive the electrolyte to circulate between the second liquid storage space 1201, the first circulation pipeline 500 and the second circulation pipeline 600. When the electrolyte flows through the portion of the first circulation pipeline 500 located in the first liquid storage space 1101, it may further exchange heat with the coolant through the first circulation pipeline 500, which is beneficial to further increase the heat exchange area between the coolant and the electrolyte, and enhance the cooling efficiency and cooling effect of the micro-arc oxidation electrolyte cooling device on the electrolyte.

[0064] It can be understood that, in actual applications, the second liquid storage space 1201 can also be used to contain cleaning liquid, so as to facilitate the internal cleaning of the second tank body 120, the circulation pump 400, the first circulation pipeline 500 and the second circulation pipeline 600, and further reduce the cleaning cost of the micro-arc oxidation electrolyte cooling device; exemplarily, when replacing the electrolyte, after the electrolyte in the second liquid storage space 1201 is discharged through the drain pipeline 300, the drain valve can be closed, and the cleaning liquid is injected into the second liquid storage space 1201 at the same time, and then the circulation pump 400 can be turned on to allow the cleaning liquid to circulate between the second liquid storage space 1201, the first circulation pipeline 500 and the second circulation pipeline 600, thereby achieving internal cleaning of the second tank body 120, the circulation pump 400, the first circulation pipeline 500 and the second circulation pipeline 600. After the cleaning is completed, the cleaning liquid can be further discharged through the drain pipeline 300, and then the drain valve is closed and the newly configured electrolyte is injected into the second liquid storage space 1201.

[0065] It is understandable that the aforementioned cleaning solution may be but is not limited to deionized water.

[0066] It can be understood that the circulation pump 400 can be fixedly arranged on the outside of the first tank body 110, and the first circulation pipeline 500 can be connected to the circulation pump 400 through a joint. Accordingly, the first circulation pipeline 500 can be passed through the tank walls of the first tank body 110 and the second tank body 120, and sealed with the first tank body 110 and the second tank body 120; the aforementioned sealing method can be but is not limited to applying sealant at the connection.

[0067] In some feasible examples, the micro-arc oxidation electrolyte cooling device may also include a temperature sensor and a controller. The temperature sensor is used to detect the electrolyte temperature in the second liquid storage space 1201. The temperature sensor and the circulation pump 400 are electrically connected to the controller. The controller is configured to control the aforementioned circulation pump 400 to turn on when the electrolyte temperature is greater than or equal to a preset temperature, and to control the aforementioned circulation pump 400 to turn off when the electrolyte temperature is less than a preset temperature. This is beneficial for shortening the working time of the circulation pump 400 while ensuring the cooling effect on the electrolyte, which is beneficial for saving the cooling operation cost of the electrolyte.

[0068] like Figure 2As shown, in some feasible examples, the first circulation pipeline 500 can be in a spiral structure, and at least part of the first circulation pipeline 500 is arranged around the circumference of the second tank body 120, so as to further increase the surface area of ​​the first circulation pipeline 500, increase the contact area between the first circulation pipeline 500 and the coolant, and further improve the cooling efficiency of the electrolyte. It is understandable that the number of turns of the first circulation pipeline 500 can be multiple; the spiral form of the first circulation pipeline 500 can be designed in combination with the shape and size of the second tank body 120, and no excessive restrictions are made here.

[0069] like Figure 2 As shown, in some examples, the second circulation pipeline 600 includes: a first pipe segment 610, one end of which is connected to the second liquid inlet end; a second pipe segment 620, which is connected to the other end of the first pipe segment 610; a driving member 630, which is used to drive the second pipe segment 620 to rotate relative to the first pipe segment 610, and the second pipe segment 620 has a first working position and a second working position; wherein, when the second pipe segment 620 is in the first working position, one end of the second pipe segment 620 away from the first pipe segment 610 is located in the second liquid storage space 1201; when the second pipe segment 620 is in the second working position, one end of the second pipe segment 620 away from the first pipe segment 610 is located outside the second liquid storage space 1201.

[0070] In this technical solution, the second circulation pipeline 600 may include a first pipe segment 610, a second pipe segment 620 and a driving member 630. Based on the above-mentioned arrangement, when it is necessary to use the circulation pump 400 to drive the electrolyte to circulate, the second pipe segment 620 can be placed in the first working position to facilitate the first pipe segment 610 to access the electrolyte; correspondingly, when it is not necessary to use the circulation pump 400 to drive the electrolyte to circulate, the second pipe segment 620 can be placed in the second working position to facilitate the second pipe segment 620 to be separated from the electrolyte, thereby shortening the contact time between the second pipe segment 620 and the electrolyte, which is beneficial to reducing the loss of the second pipe segment 620.

[0071] It can be understood that the driving member 630 can be a rotating mechanism connected between the first pipe segment 610 and the second pipe segment 620, and the rotating mechanism can be electrically connected to the aforementioned controller. The controller is configured to control the aforementioned rotating mechanism to drive the second pipe segment 620 to rotate to the first working position when the electrolyte temperature is greater than or equal to the preset temperature, and to control the aforementioned rotating mechanism to drive the second pipe segment 620 to rotate to the second working position when the electrolyte temperature is less than the preset temperature.

[0072] In some feasible examples, the first pipe segment 610 may be a plastic hose; and the second pipe segment 620 may be made of stainless steel.

[0073] In some examples, the first slot body 110 is made of insulating material.

[0074] In this technical solution, the first tank body 110 can be made of insulating material, thereby improving the safety of the first tank body 110 and preventing the micro-arc oxidation electrolyte cooling device from leaking electricity.

[0075] It can be understood that the aforementioned insulating material can be but is not limited to polytetrafluoroethylene.

[0076] like Figure 1 As shown, in some examples, the micro-arc oxidation electrolyte cooling device further includes: a plurality of legs 700 disposed on the bottom wall of the first trough body 110 .

[0077] In this technical solution, the micro-arc oxidation electrolyte cooling device may further include a plurality of legs 700. Based on the aforementioned arrangement, the plurality of legs 700 may be used to raise the first trough body 110 to a certain height to prevent the bottom wall of the first trough body 110 from contacting the external structure, thereby helping to improve the stability and safety of the first trough body 110.

[0078] It is understandable that the plurality of legs 700 may be arranged at intervals on the bottom wall of the first trough body 110 , for example, may be respectively arranged at a plurality of corner positions of the bottom wall of the first trough body 110 .
