Description

Technical Field

[0001] This utility model relates to the field of thermal management controllers, specifically a vehicle-mounted power battery thermal management controller. Background Technology

[0002] With the booming development of the new energy vehicle industry, the operating temperature of power batteries, as the core power source, has a decisive impact on charging and discharging efficiency, cycle life, and safety.

[0003] Currently, the thermal management technology of vehicle power batteries mainly adopts liquid cooling. Although liquid cooling systems can achieve temperature control, the complex pipeline design leads to high maintenance difficulty and cost. In addition, traditional liquid cooling systems mostly use fixed flow cooling, which has limited heat dissipation efficiency and is difficult to meet the heat dissipation requirements under high load conditions, resulting in energy waste.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a vehicle-mounted power battery thermal management controller, comprising: a cooling structure 1, an air intake structure 2 slidably connected to the inner wall of the top of the cooling structure 1, and a controller 3 fixedly connected to the outer wall of the top of the air intake structure 2; the air intake structure 2 includes a connecting plate 21, a support frame 22 symmetrically fixedly connected to the inner wall of the connecting plate 21, a motor 23 fixedly connected to the inner wall of the support frame 22, a fan 24 rotatably connected to the inner wall of the motor 23, symmetrically opened grooves 26 on the outer wall of the bottom of the connecting plate 21, symmetrically fixedly connected to the inner wall of the grooves 26, a sliding rod 27 slidably connected to the outer wall of the sliding rod 27, a compression plate 28 symmetrically fixedly connected to the outer wall of the compression plate 28, and a fixing block 291 and a button 292 fixedly connected to the outer wall of the compression plate 28 on the side away from the compression spring 29.

[0026] The outer wall of the top of the connecting plate 21 is fixedly connected to the outer wall of the bottom of the controller 3, and the outer wall of the fan 24 is rotatably connected to the inner wall of the support frame 22. The controller 3 adopts a commercially available Bosch EDC17 controller. The EDC17 controller obtains the real-time operating temperature status of the battery by connecting to an NTC thermistor sensor. Based on the data analysis results, the EDC17 controller sends control commands to each actuator to adjust the operating status of the motor 23.

[0027] The outer wall of the extrusion plate 28 is slidably connected to the inner wall of the slide groove 26, and the outer wall of the compression spring 29 on the side away from the extrusion plate 28 is fixedly connected to the inner wall of the slide groove 26. Pressing the button 292 pushes the extrusion plate 28 to compress the compression spring 29 along the slide groove 26 via the slide rod 27, thereby moving the fixed block 291.

[0028] The cooling structure 1 includes a mounting frame 11, with exhaust slots 12 symmetrically opened on the outer wall of the side of the mounting frame 11, a support plate 13 fixedly connected to the inner wall of the mounting frame 11, a cooling pipe 14 fixedly connected to the inner wall of the mounting frame 11, and a fixing slot 15 symmetrically opened on the outer wall of the top of the mounting frame 11.

[0029] The outer wall of the cooling pipe 14 is fixedly connected to the inner wall of the support plate 13. The outer wall of the mounting frame 11 is fixedly connected to the mounting hole plate. The cooling structure 1 is installed on the equipment through the mounting hole plate on the mounting frame 11. The internal support plate 13 is used to fix the cooling pipe 14.

[0030] The outer wall at the bottom of the connecting plate 21 contacts the outer wall at the top of the mounting frame 11, and the outer wall of the fixing block 291 is slidably connected to the inner wall of the fixing groove 15. The fixing block 291 at the bottom of the connecting plate 21 is inserted into the fixing groove 15 to achieve installation.

[0031] In use, the air intake structure 2 is installed by inserting the fixing block 291 at the bottom of the connecting plate 21 into the fixing groove 15 of the cooling structure 1, and the air intake structure 2 cools the cooling pipe 14 on the cooling structure 1. The cooling structure 1 is installed on the equipment through the mounting hole plate on the mounting frame 11, and the internal support plate 13 is used to fix the cooling pipe 14.

[0032] The Bosch EDC17 controller 3 monitors the operating temperature of the power battery in real time by connecting to an NTC thermistor sensor. When the battery temperature exceeds the threshold, it sends a command to the motor 23 of the air intake structure 2 to increase the speed of the fan 24 and enhance the air cooling effect. The coolant flowing in the cooling pipe 14 absorbs the heat from the battery and its temperature rises. The motor 23 on the support frame 22 drives the fan 24 to rotate and draws air into the cooling structure 1 through the air intake structure 2. When the airflow passes through the cooling pipe 14, it exchanges heat with the high-temperature coolant, carries away the heat, and is discharged from the exhaust duct 12, forming an air circulation for heat dissipation.

[0033] When disassembly is required for maintenance and cleaning, press button 292 to push the compression plate 28 along the slide bar 27 to compress the spring 29. The fixing block 291 will disengage from the fixing groove 15, thus separating the air intake structure 2 from the cooling structure 1 for maintenance operations. The reverse is also true.
