[0020] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0021] Reference Figure 1 , shows a flowchart of the steps of a method for manufacturing a controller housing with a liquid cooling pipeline according to an exemplary embodiment of the present application. As shown in the figure, this embodiment mainly includes the following steps:

[0022] S102, injecting the liquid to be processed into a pre-set casting mold for casting to obtain a controller housing casting.

[0023] Wherein, a liquid cooling pipeline is arranged on the controller housing casting.

[0024] Exemplarily, the liquid to be processed can be a metal liquid for casting, such as aluminum, iron, etc., which is not carried out in this embodiment. The pre-set casting mold can be set according to the size information and tolerance information of the pre-designed controller housing. The casting mold can be a die-casting mold, and the casting process can be die-casting, that is, pressure casting. Die-casting is a casting method that uses high pressure to fill liquid or semi-liquid metal into the cavity of the die-casting mold at a high speed under high pressure, and solidifies under pressure to obtain a casting. The die-casting process has a short production cycle, which can improve the production efficiency of casting; and, die-casting can obtain castings with high dimensional accuracy and good surface finish; in addition, castings with complex structures can be die-cast.

[0025] The die-casting process may also include a punching process. After die-casting is completed, the obtained casting may contain redundant parts. The punching process can further process the casting obtained by die-casting. For example, after the casting is demoulded, the punching process can be used to cut the casting and obtain a controller housing casting.

[0026] In an optional implementation, the manufacturing method of the controller housing with liquid cooling pipeline in this embodiment also includes: setting an overflow groove at the position of the pipe joint of the liquid cooling pipeline casting corresponding to the casting mold; during the casting process, the overflow groove is connected to the outer surface of the pipe joint of the liquid cooling pipeline casting.

[0027] For example, refer to Figure 2An overflow groove is provided on the casting mold at a position corresponding to the pipe joint of the liquid cooling pipe casting, such as a first overflow groove A and a second overflow groove B. Specifically, an overflow groove is provided on the inner surface of the pipe mouth of the casting mold for casting the pipe joint. The depth of the overflow groove can be flexibly set by technicians in this field according to actual conditions. For example, the depth of the overflow groove can be 1 mm, which is not limited in this embodiment.

[0028] During the casting process, the overflow groove is connected to the outer surface of the pipe joint of the liquid cooling pipe casting, so that excess liquid to be processed in the casting mold can flow out from the overflow groove, reducing the occurrence of flash on the outer surface of the pipe joint of the liquid cooling pipe casting.

[0029] In an optional implementation, an overflow groove is set at the position of the pipe joint of the liquid cooling pipe casting corresponding to the casting mold, including: at least two overflow grooves are set at the position of the pipe joint of the liquid cooling pipe casting corresponding to the casting mold, and the two overflow grooves are located on the same straight line along the radial direction of the pipe joint of the liquid cooling pipe casting.

[0030] For example, refer to Figure 2 A plurality of overflow grooves may be provided at positions of the casting mold corresponding to the pipe joints of the liquid cooling pipe casting. Preferably, two overflow grooves may be provided, such as a first overflow groove A and a second overflow groove B. Further, along the radial direction of the pipe joint of the liquid cooling pipe casting (e.g. Figure 2 In the dotted line direction), two overflow grooves (for example, the first overflow groove A and the second overflow groove B) are located on the same straight line, that is, on the inner surface of the pipe mouth of the casting mold for casting the pipe joint, the two overflow grooves (the first overflow groove A and the second overflow groove B) are arranged opposite to each other.

[0031] In this embodiment, by arranging at least two overflow grooves at the positions of the pipe joints of the liquid-cooling pipe casting in the casting mold, and the two overflow grooves are located on the same straight line along the radial direction of the pipe joints of the liquid-cooling pipe casting, the efficiency of excess liquid to be processed in the casting mold flowing out of the overflow grooves can be improved, thereby further avoiding the generation of burrs on the outer surface of the pipe joints of the liquid-cooling pipe casting.

[0032] In an optional implementation, before using computer numerical control machining to deburr the pipe joints of the liquid cooling pipe casting, the manufacturing method of the controller housing with a liquid cooling pipe in this embodiment also includes: grinding the outer surface of the liquid cooling pipe casting according to a preset roughness requirement.

[0033] For example, after obtaining the controller housing casting, the outer surface of the liquid cooling pipe casting can be ground according to the preset roughness requirements. The roughness requirement refers to the pre-designed standard for the surface roughness of the controller housing. The surface roughness refers to the unevenness of the small spacing and tiny peaks and valleys on the machined surface. The distance (wave distance) between two wave peaks or two wave valleys is very small (less than 1 mm), which belongs to the microscopic geometric shape error.

[0034] The grinding process can adopt the process of vibration grinding. Vibration grinding is to use the vibration generated by the vibration motor to make the grinding container (usually a cylinder or other shaped container with grinding media) produce regular vibration. During the vibration process, the grinding media (such as ceramic beads, steel balls, silicon carbide abrasives, etc.) collide and rub with the workpiece being ground (such as the controller housing casting in this embodiment), remove the burrs and oxide layers on the surface of the workpiece being ground, and polish the workpiece being ground. Usually, the equipment used in the vibration grinding process is a vibration grinder, which is composed of a motor, a vibration disk, a spring and other components. In addition, in addition to using the grinding media, in order to improve the grinding effect, grinding aids such as grinding fluid can usually be added. The grinding fluid can play the role of lubrication, cooling, rust prevention, etc. To reduce the friction between the grinding media and the workpiece being ground, prevent the workpiece being ground from overheating and deformation during the grinding process, and also prevent the workpiece being ground from rusting.

[0035] In this embodiment, after obtaining the controller housing casting, the outer surface of the liquid cooling pipeline casting is ground so that the surface of the controller housing casting meets the roughness requirements and the finished product accuracy of the controller housing can be improved.

[0036] S104. Deburring the pipe joints of the liquid cooling pipes by computer numerical control machining.

[0037] Exemplarily, computer numerical control machining (Computer Numerical Control Machining) or CNC machining is a manufacturing technology that uses a digital control system for automated machining. Before machining, it is necessary to use special computer-aided design (CAD) and computer-aided manufacturing (CAM) software to design a three-dimensional model of the workpiece to be machined (e.g., the pipe joint of the liquid cooling circuit of the present embodiment), and generate a tool path. These tool paths are stored in a computer in the form of digital codes. When machining begins, the digital control system reads these code instructions and converts them into motion control signals of each coordinate axis (such as X, Y, Z axis) of the machining machine tool, driving the tool to perform machining operations such as cutting, drilling, and milling on the workpiece to be machined according to a pre-set path.

[0038] Deburring the pipe joints of the liquid cooling pipes by computer numerical control machining can achieve high-precision machining and avoid damage or injury to the outer surface of the pipe joints of the liquid cooling pipes during the deburring process.

[0039] S106, assembling the deburred controller housing casting and the pre-cast liquid cooling cover plate to obtain a controller housing.

[0040] Exemplarily, the deburred controller housing casting and the pre-cast liquid cooling cover plate are assembled and connected by welding to obtain the controller housing, which can then be cleaned, deburred, and processed in other ways, but this embodiment does not limit this.

[0041] In this embodiment, the processing process of the pre-cast liquid-cooled cover plate can be as follows: the liquid to be processed is injected into a pre-set casting mold of the liquid-cooled cover plate for casting to obtain a liquid-cooled cover plate casting, and then the surface of the liquid-cooled cover plate casting is ground to meet the preset roughness requirements. Furthermore, the liquid-cooled cover plate casting can be deburred by computer numerical control machining, and then the deburred liquid-cooled cover plate casting is cleaned to obtain the liquid-cooled cover plate.

[0042] In an optional implementation, the deburred controller housing casting and the pre-cast liquid cooling cover plate are assembled to obtain the controller housing, including: cleaning the deburred controller housing casting; welding the pre-cast liquid cooling cover plate to the controller housing casting to obtain the controller housing.

[0043] Exemplarily, the controller housing casting after deburring is cleaned, and the treatment method can be water washing. Then the pre-cast liquid cooling cover plate is welded to the controller housing casting to obtain the controller housing. The welding method can be stir friction welding, and stir friction welding (Fr ict ion St ir Welding, referred to as FSW) is a new type of solid phase welding technology. Stir friction welding mainly relies on a stirring head to achieve welding. The stirring head consists of a shoulder and a stirring needle. During the welding process, the stirring head rotates at high speed and is inserted into the butt joint between the two workpieces to be welded (for example, the liquid cooling cover plate and the controller housing casting of this embodiment). The shoulder is in close contact with the surface of the workpiece to be processed, and the stirring needle stirs the material on the surface of the workpiece to be processed. Due to the rotation of the stirring head, the material around the stirring needle is violently stirred, generating friction heat. This friction heat softens the material, and the softened material flows from the front to the rear of the stirring needle under the axial pressure of the stirring head, and cools and solidifies behind the stirring head, thereby realizing the connection of the two workpieces to be processed. Friction stir welding can improve welding quality and reduce welding quality problems.

[0044] After obtaining the controller housing casting, this embodiment first cleans the deburred controller housing casting to remove pollutants, metal residues, etc. remaining on the surface of the controller housing casting, and then welds the pre-cast liquid cooling cover plate to the controller housing casting to obtain the controller housing, thereby improving the quality of the finished controller housing.

[0045] In an optional implementation, the manufacturing method of the controller housing with a liquid cooling pipeline in this embodiment further includes: deburring the controller housing by computer numerical control machining; and cleaning the deburred controller housing.

[0046] For example, after obtaining the controller housing, the controller housing can be deburred by computer numerical control machining, and then the deburred controller housing is cleaned, thus completing the manufacturing process of the controller housing.

[0047] In this embodiment, the controller housing is deburred by computer numerical control machining, which can achieve high-precision machining, avoid damage or injury to the outer surface of the controller housing during the deburring process, and improve the production qualification rate.

[0048] The manufacturing method of the controller housing with liquid cooling pipeline in the embodiment of the present application is as follows: first, the liquid to be processed is injected into a pre-set casting mold for casting to obtain a controller housing casting, on which a liquid cooling pipeline is provided; secondly, the pipe joints of the liquid cooling pipeline are deburred by computer numerical control machining; finally, the deburred controller housing casting and the pre-cast liquid cooling cover plate are assembled to obtain the controller housing. After the controller housing casting is obtained by casting, the embodiment of the present application uses computer numerical control machining to deburr the pipe joints of the liquid cooling pipeline, which can ensure that the burrs on the surface of the pipe joints of the liquid cooling pipeline are removed without damaging the surface of the pipe joints, thereby avoiding leakage at the pipeline connection due to damage to the surface of the pipe joints of the liquid cooling pipeline.

[0049] Reference Figure 3 , shows a flow chart of the steps of a detection method of a controller with a liquid cooling pipeline according to an exemplary embodiment of the present application. As shown in the figure, this embodiment mainly includes the following steps:

[0050] S302: Use a first detection device to perform air tightness detection on the liquid cooling pipeline on the controller housing.

[0051] The controller housing is manufactured by the manufacturing method of the controller housing with a liquid cooling pipeline in the aforementioned embodiment.

[0052] Exemplarily, after the controller housing is manufactured by the manufacturing method of the controller housing with a liquid cooling pipeline of the aforementioned embodiment, a first detection device can be used to perform a first air tightness test on the liquid cooling pipeline on the controller housing. During the test, the first detection device can be connected to the pipe joint of the liquid cooling pipeline.

[0053] In an optional implementation, a first detection device is used to perform an air-tightness test on the liquid cooling pipeline on the controller housing, including: wrapping the outer surface of the pipe connector of the liquid cooling pipeline on the controller housing with the first detection device to perform an air-tightness test, and the first detection device is used to simulate a female end connector that matches and connects to the pipe connector of the liquid cooling pipeline on the controller housing.

[0054] Exemplarily, the pipe connector of the liquid cooling pipeline on the controller housing can be a male connector, such as a male connector of an NW-type pipe connector. When the first detection device is used to perform air tightness detection on the liquid cooling pipeline on the controller housing, the first detection device can be used to simulate a female connector that is matched and connected to the pipe connector of the liquid cooling pipeline on the controller housing. For example, the first detection device can simulate the female connector of an NW-type pipe connector. During detection, the first detection device is used to wrap the outer surface of the pipe connector of the liquid cooling pipeline on the controller housing.

[0055] In this embodiment, the first detection device simulates the female connector that matches the pipe connector of the liquid cooling pipe on the controller housing, and the outer surface of the pipe connector of the liquid cooling pipe on the controller housing is wrapped for detection, thereby simulating the usage in actual scenarios and improving the accuracy of air tightness detection.

[0056] S304: Use a second detection device to perform air tightness detection on the liquid cooling pipeline on the controller to complete the detection of the controller.

[0057] The controller is obtained by assembling a controller housing and a prefabricated controller circuit component.

[0058] Exemplarily, the pre-manufactured controller circuit assembly can be a PCB circuit board, and the controller circuit assembly can be encapsulated in a controller housing to obtain an assembled controller. After obtaining the controller, a second detection device is further used to perform a second air tightness test on the liquid cooling pipeline on the controller to complete the air tightness test on the controller. Here, the second detection device is different from the first detection device. This embodiment is for a controller housing manufactured by the manufacturing method of a controller housing with a liquid cooling pipeline of the aforementioned embodiment. In the case where the manufacturing process has tried to avoid damage to the pipe joints of the liquid cooling pipeline, multiple air tightness tests are further performed, which can improve the qualified rate of finished products of the controller and greatly avoid leakage at the pipe connection after the whole vehicle is assembled.

[0059] In an optional implementation, a second detection device is used to perform an air tightness test on the liquid cooling pipeline on the controller, including: using the second detection device to connect with the port of the pipe connector of the liquid cooling pipeline on the controller to perform an air tightness test, and the second detection device does not contact the outer surface of the pipe connector of the liquid cooling pipeline on the controller.

[0060] Exemplarily, after the controller is assembled, a second detection device is further used to perform an air tightness test on the liquid cooling pipeline on the controller. The second detection device is different from the first detection device. During the test, the second detection device does not contact the outer surface of the pipe connector of the liquid cooling pipeline on the controller, but instead connects with the port of the pipe connector of the liquid cooling pipeline on the controller to perform an air tightness test.

[0061] In this embodiment, the second detection device is connected to the port of the pipe joint of the liquid cooling pipe on the controller to perform an airtightness test. The second detection device does not contact the outer surface of the pipe joint of the liquid cooling pipe on the controller, thereby avoiding damage to the outer surface of the pipe joint of the liquid cooling pipe during the detection process, which may cause leakage when the controller is subsequently connected to the whole vehicle.

[0062] In an optional implementation, after using a second detection device to perform airtightness detection on the liquid cooling pipeline on the controller, the detection method of the controller with a liquid cooling pipeline in this embodiment also includes: using a third detection device to detect the target position of the pipe joint of the liquid cooling pipeline on the controller, and the target position is the position on the outer surface of the pipe joint for installing the sealing component.

[0063] Exemplarily, after the second detection device is used to detect the air tightness of the liquid cooling pipeline on the controller, the outer surface of the pipeline joint of the liquid cooling pipeline can be further detected. Specifically, the third detection device can be used to detect the target position of the pipeline joint of the liquid cooling pipeline on the controller, and the target position is the position on the outer surface of the pipeline joint for installing the sealing component. Here, the sealing component can be a sealing ring or other sealing components, and this embodiment does not limit this.

[0064] In this embodiment, a third detection device is used to detect the target position of the pipe joint of the liquid cooling pipe on the controller. The target position is a position on the outer surface of the pipe joint for installing the sealing component. A final inspection can be performed before the controller is installed on the whole vehicle to ensure that the outer surface of the pipe joint of the liquid cooling pipe on the controller is not damaged, so as to avoid damage to the outer surface of the pipe joint of the liquid cooling pipe on the controller, which may cause leakage at the pipe connection with the whole vehicle.

[0065] The detection method of the controller with liquid cooling pipeline provided in the embodiment of the present application is to use a first detection device to perform air tightness detection on the pipe joints of the liquid cooling pipeline on the controller housing manufactured by the manufacturing method of the controller housing with liquid cooling pipeline of the aforementioned embodiment; then, assemble the controller housing and the pre-manufactured controller circuit assembly to obtain the controller; and then use a second detection device to perform air tightness detection on the pipe joints of the liquid cooling pipeline on the controller to complete the detection of the controller. By repeatedly performing air tightness detection at different production stages of the controller, the qualified rate of the liquid cooling pipeline in the controller is improved, thereby avoiding leakage at the pipeline connection after the whole vehicle is assembled.
