[0056] A large amount of heat is generated during the use of a battery, and if the heat cannot be dissipated in time, it will seriously affect the performance and life of the battery. At present, a water cooling plate is usually used to dissipate heat from the battery.

[0057] The applicant of the present application found that in the case of a knock on the bottom of the battery box, the water cooling plate is recessed, the function of the water cooling plate is affected, and the performance of the corresponding battery is also affected. The embodiments of the present application provide a deformation control method and equipment for a pipeline device. The inflation assembly in the deformation control equipment is used to inflate the pipe opening of the medium pipeline, and the air extraction assembly is used to extract air from the first chamber between the inner wall of the shell and the outer peripheral wall of the medium pipeline. The inflation assembly and the air extraction assembly cooperate to generate a pressure difference between the medium pipeline and the first chamber, so that the pipeline device deforms. In the case that the pipeline device is, for example, subjected to a collision to generate a recessed area, the deformation correction of the recessed area of the pipeline device is realized by the embodiments provided by the present application, so as to restore the recessed area. If the management device includes a heat exchange element, the heat exchange function of the heat exchange element can be ensured, and correspondingly, the performance of the battery can be ensured.

[0058] Figure 1 is a structural schematic diagram of a deformation control equipment for a pipeline device provided by the embodiments of the present application, as Figure 1 shown, the pipeline device 100 can include a shell 11 and a medium pipeline 12 located in the shell 11. Figure 1The medium pipeline is not shown, the pipeline device 100 can be a component capable of heat exchange, for example, the management device 100 can be a heat exchange component. The medium pipeline can be a pipeline capable of transmitting a medium, and the medium can include a liquid or a gas, etc. Alternatively, the pipeline device 100 can include a water cooling plate, the medium pipeline can include a water cooling pipe, and the medium can include a cooling liquid.

[0059] The deformation control device 200 can include an inflation component 21 and a suction component 22, the inflation component 21 is used to communicate with the pipe opening of the medium pipeline, and the inflation component 21 is used to inflate the medium pipeline.

[0060] The inflation component 21 can be a component capable of pressurized inflation. For example, if the pipeline device 100 is a water cooling plate, the inflation component 21 can be a water inlet 12a and a water outlet 12b. Figure 2 The pipe opening of the medium pipeline can include the pipe opening of the water cooling pipe, and the pipe opening can include the water inlet 12a and the water outlet 12b.

[0061] In the embodiments of the present application, the inflation component 21 can communicate with the water inlet 12a and the water outlet 12b, or the inflation component 21 communicates with one of the water inlet 12a and the water outlet 12b, and the other of the water inlet 12a and the water outlet 12b is sealed.

[0062] The suction component 22 is used to communicate with the first chamber, and the first chamber includes the chamber between the inner wall of the shell 11 and the outer peripheral wall of the medium pipeline, and the suction component 22 is used to suck the first chamber. For example, the air pressure of the suction component 22 is not less than 8 bar (bar).

[0063] It should be noted that, in the case where the pipeline device does not have a recessed area, there is a first chamber between the inner wall of the shell 11 and the outer peripheral wall of the medium pipeline. Alternatively, in the case where the pipeline device does not have a recessed area, there is no first chamber between the inner wall of the shell 11 and the outer peripheral wall of the medium pipeline. In the case where the pipeline device does not have a recessed area, due to the recess, part of the inner wall of the shell 11 and part of the outer peripheral wall of the medium pipeline are deformed, and thus part of the inner wall and part of the outer peripheral wall form the first chamber.

[0064] The inflation component 21 is used to inflate the pipe opening of the medium pipeline, and the suction component 22 is used to suck the first chamber, thereby generating a pressure difference between the medium pipeline and the first chamber, and the pipeline device is deformed. In the case where the pipeline device, for example, has a recessed area due to a collision, the deformation of the recessed area of the pipeline device 100 is corrected by one or more embodiments provided in the present application, so as to restore the recessed area.

[0065] In summary, the embodiment of the present application provides a deformation control device of a pipeline device. The inflation assembly is used to inflate the pipe opening of the medium pipeline, and the air extraction assembly is used to extract air from the first chamber between the inner wall of the shell and the outer peripheral wall of the medium pipeline. The inflation assembly and the air extraction assembly cooperate with each other to generate a pressure difference between the medium pipeline and the first chamber, so that the pipeline device deforms. In the case that the pipeline device, for example, is subjected to a collision to generate a concave area, the deformation correction of the concave area of the pipeline device is realized by the embodiment of the present application to restore the concave area.

[0066] If the management device includes a heat exchange element, after the pipeline device 100 is subjected to a collision at the bottom of the battery to generate a concave area, the heat exchange function of the pipeline device 100 is reduced, thereby affecting the performance of the battery. By repairing the concave area of the pipeline device 100, the height of the medium pipeline is corrected, the heat exchange function of the pipeline device 100 is restored, the performance of the battery is restored, the battery is prevented from being scrapped, and the service life of the battery is prolonged.

[0067] Reference Figure 3 The shell 11 is provided with a first through hole 12 in communication with the first chamber. Reference Figure 4 and Figure 5 The air extraction assembly 22 can include an air extraction pump (not shown) and a gas transmission pipe 221. The material of the gas transmission pipe 221 can be a rigid material. Figure 1 、 Figure 4 and Figure 5 are not shown) and a gas transmission pipe 221. The material of the gas transmission pipe 221 can be a rigid material.

[0068] The air extraction pump is connected to one end of the gas transmission pipe 221, and the other end of the gas transmission pipe 221 is in communication with the first through hole 12, thereby realizing communication between the first through hole 12 and the first chamber. The air extraction pump can extract the gas in the first chamber through the gas transmission pipe 221 and the first through hole 12.

[0069] Reference Figure 4 and Figure 5 ( Figure 5 not shown), the air extraction assembly 22 can further include a matching device 222, and the matching device 222 is provided with an air extraction pipeline. The air extraction pipeline is provided with an air extraction hole 222a located on the matching surface of the matching device 222.

[0070] The air extraction hole 222a is in communication with the first through hole 12, and the other end of the gas transmission pipe 221 is in communication with the air extraction pipeline. The air extraction pump can extract the gas in the first chamber through the gas transmission pipe 221, the air extraction pipeline, the air extraction hole 222a and the first through hole 12.

[0071] Reference Figure 3 A part of the medium pipeline 13 is exposed to the shell 11. Reference Figure 4 ( Figure 4 ​​The medium pipeline 13 is not shown, and the fitting surface is provided with a profiling groove formed in the shape of the medium pipeline 13. A part of the medium pipeline is adapted to be embedded in the profiling groove, so that the air extraction hole 222a is arranged opposite to the first through hole 12 to communicate, and the fitting surface and the shell 11 can be embedded to ensure air tightness.

[0072] In the process of inflating the medium pipeline by the inflation assembly 21 and extracting air from the first chamber by the air extraction assembly 22, the profiling groove can ensure that the shell of the medium pipeline is deformed according to the shape of the profiling groove, so as to repair the recessed area. The depth of the profiling groove is greater than the protruding height of the medium pipeline 13 protruding from the shell 11, so that the recessed area has a certain deformation space during the repair of the recessed area, and the repair quality of the recessed area is controllable. Optionally, the difference between the depth of the profiling groove and the protruding height is within a preset range, and the lower limit of the preset range can be 1 millimeter (mm), and the upper limit can be 2 mm.

[0073] In the embodiment of the present application, the fitting surface and the shell 11 can be sealed, so as to ensure the air tightness of the fitting surface and the shell 11, ensure the reliability of air extraction, and further ensure the efficiency and reliability of restoring the pipeline device 100. Optionally, the fitting surface and the shell 11 can be sealed by bonding, for example, the periphery of the fitting surface and the shell 11 are sealed by bonding. Alternatively, a sealing strip can be arranged between the fitting surface and the shell 11 to seal the fitting surface and the shell 11 by the sealing strip. For example, the sealing strip can be foam. Alternatively, the fitting surface and the shell 11 can be sealed by bolt locking.

[0074] As an optional implementation, referring to Figure 3 and Figure 6 ( Figure 6 The medium pipeline 13 is not shown, and the fitting surface is provided with a profiling groove formed in the shape of the medium pipeline 13. A part of the medium pipeline is adapted to be embedded in the profiling groove, so that the air extraction hole 222a is arranged opposite to the first through hole 12 to communicate, and the fitting surface and the shell 11 can be embedded to ensure air tightness.

[0075] Optionally, the area where the part of the medium pipeline 13 is located can be the area where the pipeline device 100 is recessed, that is, the air extraction hole 222a on the fitting surface is located in the recessed area. By using this implementation, the recessed area of the pipeline device 100 can be locally restored to realize local repair.

[0076] Since the area where the partial medium pipeline 13 is located is the area where the pipeline device 100 is recessed, that is, the air extraction hole 222a on the matching surface is located in the area where the recess is generated, the staff can select a suitable inflation pressure and negative pressure based on the degree of recess of the recessed area, so that a larger pressure difference is generated at the recessed area during the process of inflating the medium pipeline by the inflation assembly 21 and extracting the first chamber by the air extraction assembly 22, and the larger pressure difference can restore the recessed area. In addition, by setting a suitable inflation pressure, the pressure difference of other normal areas can be small, so that the other normal areas will not be deformed.

[0077] As another optional implementation, referring to Figure 3 and Figure 7 ( Figure 7 The medium pipeline 13 is not shown), the matching surface covers the surface of the shell 11, and the profiling groove is embeddedly matched with a part of all medium pipelines 13.

[0078] In the case where the pipeline device 100 has multiple recessed areas, in this implementation, the air extraction hole 222a on the matching surface can be located at multiple recessed areas, so that the pipeline device 100 can be restored as a whole to achieve overall maintenance, thereby improving the maintenance efficiency. In this implementation, the inflation pressure of the inflation assembly 21 to the pipe opening of the medium pipeline 13 can be 3.5 kilo pascal (Kpa).

[0079] Since the profiling groove is embeddedly matched with a part of all medium pipelines 13, and the air extraction hole 222a on the matching surface can be located at multiple recessed areas, a suitable inflation pressure matched with the degree of recess of the largest recessed area can be provided to the medium pipeline based on the largest recessed area, and a negative pressure matched with the degree of recess of the largest recessed area can be provided to the first chamber, so that a larger pressure difference is generated at the largest recessed area and other recessed areas, thereby restoring the multiple recessed areas.

[0080] Since the depth of the profiling groove is greater than the protruding height of the medium pipeline 13 protruding from the shell 11, the larger pressure difference provided to other recessed areas based on the largest recessed area will not cause other recessed areas to be deformed. In addition, by setting a suitable inflation pressure, the pressure difference of other normal areas can be small, so that the other normal areas will not be deformed.

[0081] In the embodiments of the present application, the matching device 222 can be a cube, for example, referring to Figure 4 The matching device 222 can be a cuboid. Alternatively, referring to Figure 7 ( Figure 7 The pipeline device 100 is not shown), the shape of the matching device 22 is the same as that of the pipeline device 100.

Referring to Figure 3 Figure 3 (not shown) and each gas suction pipe is provided with a gas suction hole 222a, and the plurality of gas suction holes 222a are in one-to-one correspondence with the plurality of first through holes 12. As shown in the example, Figure 3 The ten first through holes 12 are in one-to-one correspondence with the ten gas suction holes. Referring to Figure 5 The plurality of gas pipes 221a are in one-to-one correspondence with the plurality of gas suction pipes, and one end of each of the plurality of gas pipes 221a is connected to the gas suction pump. This implementation is suitable for partial restoration or overall restoration of the pipeline device 100.

The inflation assembly and the gas suction assembly cooperate with each other to generate a pressure difference between the medium pipe and the first chamber, so that the pipeline device deforms. In the case that the pipeline device, for example, is subjected to collision to generate a concave area, the deformation correction of the concave area of the pipeline device is realized by the embodiment of the present application to restore the concave area.

Optionally, the maintenance personnel can seal the fitting surface with the shell by adhesion, or can set a sealing strip between the fitting surface and the shell to seal the fitting surface with the shell by the sealing strip. For example, the sealing strip can be a foam.

[0102] As an optional implementation, referring to Figure 6 ( Figure 6 not shown in the medium pipeline 13), the area of the fitting surface is less than the area of the surface of the shell 11, and the profiling groove is fitted with a part of the medium pipeline 13. Optionally, the area where the medium pipeline 13 is located can be the area where the pipeline device is recessed. By using this implementation, the local recovery of the area where the pipeline device is recessed can be realized.

[0103] As another optional implementation, referring to Figure 7 ( Figure 7 not shown in the medium pipeline 13), the fitting surface covers the surface of the shell 11, and the profiling groove is fitted with a part of all the medium pipelines 13. By using this implementation, the overall recovery of the pipeline device can be realized.

[0104] In an optional implementation of the embodiment of the present application, referring to Figure 3 , the first through hole 12 can be one, and referring to Figure 4 , the suction hole 222a can be one. The maintenance personnel can arrange the one suction hole 222a opposite to the one first through hole 12 to communicate.

[0105] In another optional implementation of the embodiment of the present application, referring to Figure 3 , the number of the first through holes 12 is multiple. The number of the suction holes 222a is also multiple, and the multiple suction holes 222a and the multiple first through holes 12 correspond one by one. For each of the multiple suction holes 222a, the maintenance personnel can arrange the suction hole 222a opposite to the corresponding one first through hole 12 to communicate.

[0106] Step 903, determining a target inflation gear based on the recess degree of the pipeline device.

[0107] The inflation assembly can include a plurality of inflation gears. After the maintenance personnel connects the inflation assembly with the pipe opening of the medium pipeline and connects the air extraction assembly with the first chamber, the target inflation gear can be determined based on the recess degree of the pipeline device.

[0108] The target inflation gear is positively correlated with the recess degree, that is, the higher the recess degree, the higher the target inflation gear, and the lower the recess degree, the lower the target inflation gear.

[0109] Step 904, adjusting the inflation gear of the inflation assembly to the target inflation gear, so that the inflation assembly inflates the medium pipeline according to the target inflation gear.

[0110] After the maintenance personnel determines the target inflation gear, the maintenance personnel can adjust the inflation gear of the inflation assembly to the target inflation gear, and start the inflation assembly to inflate the medium pipeline according to the target inflation gear.

[0111] The inflation assembly inflates the medium pipeline at different pressures at different inflation gears. The inflation pressure is positively correlated with the inflation gear, that is, the higher the inflation gear, the higher the inflation pressure, and the lower the inflation gear, the lower the inflation pressure.

[0112] Step 905, adjusting the air extraction gear of the air extraction assembly to the target air extraction gear, so that the air extraction assembly extracts air from the first chamber according to the target air extraction gear.

[0113] The air extraction assembly can include a plurality of air extraction gears. After the maintenance personnel connects the inflation assembly with the pipe opening of the medium pipeline and connects the air extraction assembly with the first chamber, the maintenance personnel can also adjust the air extraction gear of the air extraction assembly to the target air extraction gear, so that the air extraction assembly extracts air from the first chamber according to the target air extraction gear.

[0114] After the maintenance personnel connects the inflation assembly with the pipe opening of the medium pipeline and connects the air extraction assembly with the first chamber, the target air extraction gear can be determined based on the recess degree of the pipeline device.

[0115] The target air extraction gear is positively correlated with the recess degree, that is, the higher the recess degree, the higher the target air extraction gear, and the lower the recess degree, the lower the target air extraction gear.

[0116] The air extraction assembly extracts air at different air extraction rates at different air extraction gears. The air extraction rate can be positively correlated with the air extraction gear.

[0117] It can be understood that, in the case of local repair of the pipeline device, the worker can set a suitable target inflation gear and target exhaust gear based on the recess degree of the recessed area, which can ensure that the pressure difference at the recessed area is large and the pressure difference at the other normal areas is small, thereby ensuring that only the recessed area deforms and the other normal areas are not affected.

[0118] In the case of overall repair of the pipeline device, the worker can determine the inflation gear and exhaust gear matching the recess degree of the maximum recessed area based on the maximum recessed area, so that the pressure difference at the maximum recessed area is large and the pressure difference at the other normal areas is small, thereby ensuring that the maximum recessed area and other recessed areas recover and the other normal areas do not deform. In addition, since the depth of the profiling groove is greater than the protruding height of the medium pipeline 13 protruding from the shell 11, the other recessed areas can only recover to the depth of the profiling groove under the control of a large pressure difference, and will not have a large deformation.

[0119] In the embodiments of the present application, the target exhaust gear and the target inflation gear matching the recess degree are determined based on the recess degree of the pipeline device, which improves the efficiency of repairing the recessed area while ensuring that the recessed area recovers.

[0120] After the pipeline device recovers, the pipe opening of the medium pipeline of the pipeline device can be inflated for air tightness detection. If the leakage rate in the tank is less than 75 Pa after the pressure is stabilized for 60 s. Or, the helium leakage amount is less than 2x10^-8 Pa*m 3 S. Or, no bubbles are detected in water, indicating good air tightness.

[0121] In summary, the embodiments of the present application provide a deformation control method for a pipeline device. In the method, the pipe opening of the medium pipeline is inflated by the inflation assembly, and the first chamber between the inner wall of the shell and the outer peripheral wall of the medium pipeline is exhausted by the exhaust assembly. The inflation assembly and the exhaust assembly cooperate to generate a pressure difference between the medium pipeline and the first chamber, so that the pipeline device deforms. In the case that the pipeline device, for example, is subjected to collision to generate a recessed area, the deformation of the recessed area of the pipeline device is corrected by the embodiments provided by the present application to recover the recessed area, thereby ensuring the heat exchange function of the pipeline device.
