Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically to a waste heat recovery storage tank for motors. Background Technology

[0002] Waste heat recovery storage tanks for new energy vehicle motors are a key technology for improving vehicle energy efficiency and winter range. Their core function is to store the waste heat generated during motor operation and release it as needed for battery preheating, cabin heating, and other applications. During operation, motors generate approximately 10%-20% waste heat due to copper and iron losses, typically ranging from 60-120°C. The storage tank absorbs this heat through a closed-loop coolant circuit (such as a 50% ethylene glycol aqueous solution), utilizing the latent heat storage characteristics of phase change materials (PCMs) to achieve efficient energy storage. For example, a patented thermal management system uses a flow path selection component to store motor waste heat in the storage tank and then heats the battery pack via a battery preheating circuit when needed.

[0003] In existing waste heat recovery tanks, heat transfer efficiency is affected by the deposition of impurities in the coolant on the inner wall of the pipes during long-term use, resulting in heat loss. In addition, most existing phase change materials are placed directly inside the heat storage tank, making it easy for heat to dissipate. Utility Model Content

[0004] The purpose of this utility model is to provide a waste heat recovery storage tank for motors to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A waste heat recovery storage tank for motors includes a tank body with an inlet pipe and an outlet pipe at both ends. A scrubbing mechanism is installed inside the tank. The inlet pipe extends into the tank body and connects to multiple branch pipes. Each branch pipe is connected to an annular pipe, and the annular pipe is connected to a distribution pipe. The scrubbing mechanism is used to scrub the inner wall of the distribution pipe. The scrubbing mechanism includes annular teeth disposed inside the tank body. A transmission tooth is rotatably connected to the distribution pipe, and the transmission tooth meshes with the annular tooth. Multiple scrapers are fixedly connected to the transmission tooth.

[0006] A further improvement of the present invention is that the washing mechanism further includes a motor, which is installed inside the tank. The output end of the motor is fixedly connected to the ring gear. The liquid distribution tube consists of two sections, and the transmission gear is rotatably connected between the two liquid distribution tubes. A connecting seat is fixedly connected to the liquid distribution tube, and the connecting seat is used to connect the upper and lower liquid distribution tubes.

[0007] A further improvement of this utility model is that: a plurality of heat transfer plates are fixedly connected to the outer wall of the liquid separator, a sealing box is fixedly connected to the outer wall of the heat transfer plates, and a phase change material for heat storage is provided between the sealing box and the heat transfer plates.

[0008] A further improvement of this utility model is that: the liquid distribution pipe and the liquid outlet pipe are also connected by an annular pipe and a branch pipe, and a filtration mechanism is installed on the liquid inlet pipe.

[0009] A further improvement of the present invention is that the filtration mechanism includes a filter plate, the filter plate and the inlet pipe are slidably connected, a fixed cylinder is connected to the inlet pipe, the fixed cylinder is used to fix the filter plate connection, an electric push rod is installed on the tank, and the telescopic end of the electric push rod is fixedly connected to the filter plate.

[0010] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a waste heat recovery storage tank for motors. By setting a scrubbing mechanism inside the tank, it realizes automatic scrubbing of the inner wall of the liquid separator, effectively preventing the problem of scaling on the inner wall caused by long-term use and ensuring stable heat exchange efficiency. At the same time, the motor in the scrubbing mechanism drives the ring gear to rotate, which in turn drives the transmission gear and scraper to thoroughly scrub the inner wall of the liquid separator. The design is ingenious and highly practical.

[0014] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-5 As shown, this utility model provides a waste heat recovery storage tank for motors, comprising a tank body 1, with an inlet pipe 2 and an outlet pipe 8 respectively provided at both ends of the tank body 1. A scrubbing mechanism 7 is provided inside the tank body 1. The inlet pipe 2 extends into the tank body 1 and is connected to multiple branch pipes 6. The branch pipes 6 are connected to an annular pipe 5, and the annular pipe 5 is connected to a distribution pipe 4. The scrubbing mechanism 7 is used to scrub the inner wall of the distribution pipe 4. The scrubbing mechanism 7 includes annular teeth 74, which are disposed inside the tank body 1. A transmission tooth 75 is rotatably connected to the distribution pipe 4, and the transmission tooth 75 meshes with the annular tooth 74. Multiple scrapers 76 are fixedly connected to the transmission tooth 75.

[0015] The cleaning mechanism 7 is designed to clean the inner wall of the separator 4, removing impurities deposited on it. This increases heat transfer efficiency, avoids increased thermal resistance due to impurity buildup, and effectively improves the efficiency of waste heat recovery from the motor. Simultaneously, the cleaning mechanism 7 is driven by a motor 73 to rotate the ring gear 74, which in turn drives the transmission gear 75 meshing with the ring gear 74 to rotate. This allows the scraper 76, fixed to the transmission gear 75, to thoroughly and effectively clean the inner wall of the separator 4, ensuring its cleanliness.

[0016] Furthermore, the multiple heat transfer plates 72 fixedly connected to the outer wall of the liquid separator 4, along with the sealed box 71 and phase change material installed on the outer wall of the heat transfer plates 72, together constitute a highly efficient heat storage system. The phase change material can absorb or release a large amount of heat when the temperature changes, thereby achieving stable storage and effective utilization of the motor's waste heat, further improving energy efficiency.

[0017] The filter mechanism 3 installed on the liquid inlet pipe 2 is driven by an electric push rod 31 to slide the filter plate 32 inside the liquid inlet pipe 2, thereby achieving the function of filtering the liquid entering the tank 1. The filter plate 32 can effectively intercept impurities and particulate matter in the liquid, preventing them from entering the tank 1, thus protecting the equipment and pipes inside the tank 1 from wear and blockage, and extending the service life of the equipment.

[0018] In summary, the waste heat recovery storage tank for motors provided by this utility model achieves efficient recovery and utilization of waste heat from motors through the synergistic effect of the washing mechanism 7, the heat storage system, and the filtration mechanism 3, while ensuring the cleanliness and service life of the equipment.

[0019] like Figure 3-5 As shown, the washing mechanism 7 also includes a motor 73, which is installed inside the tank 1. The output end of the motor 73 is fixedly connected to the ring gear 74. The liquid distribution pipe 4 consists of two sections, and the transmission gear 75 is rotatably connected between the two liquid distribution pipes 4. A connecting seat is fixedly connected to the liquid distribution pipe 4, and the connecting seat is used to connect the upper and lower liquid distribution pipes 4.

[0020] like Figure 3-5 As shown, a plurality of heat transfer plates 72 are fixedly connected to the outer wall of the liquid separator 4, and a sealing box 71 is fixedly connected to the outer wall of the heat transfer plate 72. A phase change material for heat storage is provided between the sealing box 71 and the heat transfer plate 72.

[0021] By cooperating with the annular pipe 5, multiple branch pipes 6, and multiple liquid distribution pipes 4, the liquid can be diverted into multiple liquid distribution pipes 4. Multiple heat sinks connected to the multiple liquid distribution pipes 4 are in contact with the phase change material, thereby further increasing the contact area between the liquid and the heat sink, resulting in higher heat transfer efficiency and less heat loss.

[0022] Example 2 like Figure 3 As shown, based on Embodiment 1, this utility model provides a technical solution: the liquid distribution pipe 4 and the liquid outlet pipe 8 are also connected by an annular pipe 5 and a branch pipe 6, and a filter mechanism 3 is installed on the liquid inlet pipe 2.

[0023] like Figure 2 As shown, the filtration mechanism 3 includes a filter plate 32, which is slidably connected to the liquid inlet pipe 2. A fixing cylinder 33 is connected to the liquid inlet pipe 2, which is used to fix the connection of the filter plate 32. An electric push rod 31 is installed on the tank body 1, and the telescopic end of the electric push rod 31 is fixedly connected to the filter plate 32.

[0024] The filter mechanism 3 can not only filter the liquid entering the inlet pipe 2, but also adsorb the impurities scraped off by the brushing mechanism 7 because the liquid is circulating. When the filter plate 32 needs to be cleaned due to excessive adsorption of impurities, the filter plate 32 can be cleaned by pulling out the electric push rod 31.

[0025] The working principle of this motor waste heat recovery storage tank is explained in detail below. When the tank is working, the liquid generated by the motor's waste heat enters the tank body 1 through the inlet pipe 2. First, it undergoes preliminary filtration through the filter plate 32 in the filtration mechanism 3, which intercepts large particles and solid particles in the liquid, preventing them from entering the tank body 1 and causing wear or blockage to subsequent equipment and pipelines. The filtered liquid continues to extend into the tank body 1 through the inlet pipe 2 and is distributed to multiple branch pipes 6. The branch pipes 6 transport the liquid to the annular pipe 5, and then the annular pipe 5 evenly distributes it to each distribution pipe 4.

[0026] As the liquid flows through the distributor pipe 4, multiple heat transfer plates 72 fixedly connected to the outer wall of the distributor pipe 4 exchange heat fully with the liquid. The sealed box 71 and phase change material installed on the outer wall of the heat transfer plates 72 begin to absorb or release heat. When the liquid temperature is high, the phase change material absorbs and stores the heat; when the liquid temperature drops and heat needs to be replenished, the phase change material releases the stored heat, thereby achieving stable storage and effective utilization of the motor's waste heat.

[0027] At the same time, the washing mechanism 7 inside the tank 1 starts to work. The motor 73 drives the ring gear 74 to rotate, and the ring gear 74 drives the transmission gear 75 that meshes with it to rotate. The multiple scrapers 76 fixedly connected to the transmission gear 75 then thoroughly and effectively wash the inner wall of the liquid distribution pipe 4, removing the impurities deposited on the inner wall of the liquid distribution pipe 4, avoiding the problem of increased thermal resistance caused by the accumulation of impurities, and further improving the heat transfer efficiency.

[0028] After heat exchange and washing, the liquid is collected in the outlet pipe 8 via the annular pipe 5 and branch pipe 6 between the separator pipe 4 and the outlet pipe 8, and finally discharged from the tank 1, completing the entire process of recovering and utilizing the waste heat of the motor. Meanwhile, the filter plate 32 in the filtration mechanism 3, after absorbing excessive impurities, can be pulled out by the electric push rod 31 for cleaning, ensuring the filtration effect and normal operation of the equipment.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
