Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for new energy battery modules, and in particular to a battery module assembly frame with heat dissipation function. Background Technology

[0002] Batteries, as the core carrier of energy storage and conversion, are widely used in electric vehicles, energy storage power stations, portable electronic devices, and industrial power systems. However, the voltage of a single battery is generally low, making it difficult to directly meet the operating requirements of high-voltage, high-power equipment. To adapt to the different voltage and capacity requirements of equipment, in practical engineering, multiple batteries are often connected in series, parallel, or mixed connections to form modular battery packs, thereby improving overall output performance.

[0003] In existing technologies, battery modules are mostly assembled using a frame-type fixed structure. A metal or engineering plastic frame mechanically constrains and electrically connects multiple batteries, and an external protective shell protects them from environmental interference such as mechanical impact and moisture intrusion. Since batteries generate heat during charging and discharging, heat accumulation can lead to increased battery temperature, accelerating electrode aging, electrolyte decomposition, and even thermal runaway. Therefore, existing assembly frames often incorporate airflow structures inside the frame or on the outer shell. Forced air cooling or natural convection is used to circulate external airflow, carrying away heat from the battery surface and maintaining the battery operating temperature within a safe threshold.

[0004] However, as external airflow enters and exits the duct, it carries dust and particulate matter, which accumulates on the frame surface, battery casing, and duct interior, forming an insulation layer that hinders heat transfer. Furthermore, the dust filters at the duct inlet / outlet are prone to blockage due to dust accumulation, leading to a reduction in airflow cross-sectional area and flow velocity, causing heat dissipation performance to continuously decline over time. This vicious cycle of "dust adhesion—increased thermal resistance—heat dissipation failure" makes it difficult for the existing frame to maintain stable and efficient heat dissipation during long-term operation, ultimately affecting the cycle life and reliability of the battery module. Utility Model Content

[0005] To overcome the drawback of dust accumulation in the external circulation system affecting heat dissipation, this invention provides a battery module assembly frame with heat dissipation function, aiming to solve the aforementioned shortcomings.

[0006] A battery module assembly frame with heat dissipation function includes an installation frame, within which several heat dissipation frames are arranged. A top cover is connected to the top of each heat dissipation frame. The top cover has several heat dissipation ducts, each containing several cooling fans. An exhaust pipe is connected to the center of the top cover, connecting all the heat dissipation ducts. A controller is installed on the front side of each heat dissipation frame. A recovery pipe, connected to the exhaust pipe, is connected to the center of the front side of each heat dissipation frame. A water tank is connected to the side of the recovery pipe. A cooler is installed on the top of the water tank. The cooler and all the cooling fans are wired to the controller. A water circulation pipe is arranged within the recovery pipe. One end of the water circulation pipe is connected to the top of the water tank via the cooler, and the other end passes through the recovery pipe and connects to the bottom front side of the water tank, where a water pump is installed. The water pump is wired to the controller. Circulation components for air recirculation are provided on the front and left and right sides of the heat dissipation frame.

[0007] Furthermore, the circulation component includes cooling pipes, and flow shields are connected to both sides of the heat dissipation frame. One end of each of the two cooling pipes is connected to the left and right sides of the recovery pipe, and the other end is connected to a diversion pipe. The diversion pipe is provided with several airflow pipes that communicate with the flow shields.

[0008] Furthermore, a baffle is rotatably connected to the rear side of the flow hood, and torsion springs are sleeved at both the top and bottom ends of the baffle's rotating shaft. One end of the torsion spring is connected to the baffle, and the other end is connected to the flow hood.

[0009] Furthermore, a guide plate is connected to the bottom of the recovery pipe, and the guide plate is provided with an inclined surface facing the two cooling pipes.

[0010] Furthermore, a liquid level sensor is installed inside the water tank, and the liquid level sensor is wired to the controller.

[0011] Furthermore, a sealing gasket is fitted at the connection between the exhaust pipe and the recovery pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The S-shaped copper water circulation pipe inside the recovery pipe facilitates efficient heat exchange with the airflow. The liquid, cooled by the cooler, continuously carries away the heat from the airflow, significantly reducing the temperature of the airflow blown into the heat dissipation duct. This, combined with the synergistic effect of the heat dissipation duct and the water circulation pipe, achieves internal circulation and efficient heat dissipation.

[0014] 2. Through the dynamic cooperation of the baffle and the torsion spring, the baffle automatically rotates to connect the flow cover with the outside world, quickly balancing the air pressure. This achieves dynamic air pressure regulation and reduces the entry of external dust through periodic opening and closing, preventing dust from accumulating on the surface of the heat dissipation frame and forming a heat insulation layer.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] Example: A battery module assembly frame with heat dissipation function, such as... Figures 1-6As shown, the system includes a heat dissipation frame 101, a top cover 2, heat dissipation ducts 3, cooling fans 4, exhaust pipes 5, a controller 6, a recovery pipe 7, a water circulation pipe 8, a water pump 801, a water tank 9, a cooler 10, and circulation components. Several heat dissipation frames 101 are installed within the mounting frame 1. The top cover 2 is connected to the top of each heat dissipation frame 101. The top cover 2 has several heat dissipation ducts 3, and several cooling fans 4 are installed within each heat dissipation duct 3. An exhaust pipe 5 is connected to the middle of the top cover 2, connecting all the heat dissipation ducts 3. A controller 6 is installed on the front side of the frame 101, and the middle of the front side of the heat dissipation frame 101 is connected to the exhaust pipe. The recycling pipe 7 is connected to the right side of the recycling pipe 7, and a water tank 9 is connected to the right side of the water tank 9. A cooler 10 is installed on the top of the water tank 9. The cooler 10 and all the cooling fans 4 are wired to the controller 6. A water circulation pipe 8 is installed inside the recycling pipe 7. One end of the water circulation pipe 8 is connected to the top of the water tank 9 through the cooler 10, and the other end passes through the recycling pipe 7 and is connected to the bottom front side of the water tank 9. A water pump 801 is installed thereon. The water pump 801 is wired to the controller 6. The water circulation pipe 8 is made of copper and is S-shaped to ensure efficient heat exchange between airflow and liquid. The front and left and right sides of the heat dissipation frame 101 are equipped with circulation components for air recirculation.

[0024] like Figure 2 and Figure 4 As shown, the circulation assembly includes a cooling pipe 11, a diversion pipe 12, and a flow shield 13. The flow shield 13 is connected to both the left and right sides of the heat dissipation frame 101. One end of the two cooling pipes 11 is connected to the left and right sides of the recovery pipe 7, and the other end is connected to the diversion pipe 12. The flow shield 13 is made of aluminum alloy with good thermal conductivity to assist in the overall heat dissipation of the battery module. The diversion pipe 12 is provided with several airflow pipes that are connected to the flow shield 13.

[0025] like Figure 4 and Figure 6 As shown, it also includes a baffle 14 and a torsion spring 15. The baffle 14 is rotatably connected to the rear side of the flow shroud 13. The top and bottom ends of the rotating shaft of the baffle 14 are fitted with torsion springs 15. The elastic coefficient of the torsion spring 15 is designed to be 0.5 N·m / rad. It is triggered to rotate under a pressure difference of 50 Pa and automatically resets after balancing. One end of the torsion spring 15 is connected to the baffle 14 and the other end is connected to the flow shroud 13.

[0026] like Figure 5 As shown, it also includes a guide plate 16. The bottom of the recovery pipe 7 is connected to the guide plate 16. The guide plate 16 is provided with an inclined surface facing the two cooling pipes 11. The inclined surface angle is 45° to optimize the airflow lifting path and avoid collision.

[0027] like Figure 5 As shown, it also includes a liquid level sensor 17, which is installed in the water tank 9 and is wired to the controller 6.

[0028] like Figure 3 As shown, it also includes a sealing gasket 18. A sealing gasket 18 is fitted at the connection between the exhaust pipe 5 and the recovery pipe 7. The sealing gasket 18 is made of silicone rubber and has a temperature resistance range of -60℃ to 220℃ to ensure the airtightness of the connection.

[0029] Workers install multiple batteries at preset intervals inside the heat dissipation frame 101. After the top cover 2 is placed on top, flow shields 13 are symmetrically connected on the left and right sides to form a closed airflow channel. When the battery module is connected to the circuit and started, the system detects the current input and automatically activates the controller 6, which controls the cooling fan 4 to start first. The cooling fan 4 guides the airflow in the exhaust pipe 5 to flow laterally along the heat dissipation channel 3 into the interior of the heat dissipation frame 101. After the airflow fully contacts the battery surface and carries away the heat, it is collected and returned by the left and right flow shields 13, and then introduced into the cooling pipe 11 through the diversion pipe 12, and finally flows into the recovery pipe 7 to complete the circulation path.

[0030] When the airflow flows in the recovery pipe 7, it triggers the liquid cooling process: the controller 6 simultaneously starts the water pump 801 and the cooler 10. The water pump 801 draws liquid from the water tank 9 and flows along the water circulation pipe 8. When the liquid flows through the cooler 10, it is cooled to the preset temperature range. Then, the outer wall of the water circulation pipe 8, which is surrounded by an S-shape in the recovery pipe 7, exchanges heat efficiently with the airflow, which significantly reduces the airflow temperature. The low-temperature airflow re-enters the heat dissipation duct 3 through the exhaust pipe 5, forming a continuous and stable low-temperature heat dissipation cycle, which effectively maintains the battery operating temperature.

[0031] To optimize airflow circulation efficiency, the guide plate 16 at the bottom of the recovery pipe 7 guides the airflow direction through its inclined design. When the airflow enters the recovery pipe 7 from the cooling pipe 11, the inclined surface of the guide plate 16 lifts the airflow upward, avoiding direct collision between the left and right airflows and preventing circulation obstruction. This ensures that the airflow on one side completes the circulation path smoothly and prevents local airflow accumulation from affecting the heat dissipation effect.

[0032] The liquid level sensor 17 installed in the water tank 9 monitors the liquid volume in real time. If the liquid level is detected to be lower than the safety threshold, the system will trigger a liquid shortage alarm to prompt the staff to replenish water in time, ensuring the continuous and effective operation of the liquid cooling system. The sealing gasket 18 at the connection between the exhaust pipe 5 and the recovery pipe 7 has an elastic sealing design to effectively prevent gas from escaping, maintain the airtightness of the airflow circulation system, and prevent external air from seeping in and interfering with the heat dissipation efficiency.

[0033] When the circulating airflow decreases due to pressure fluctuations or localized leakage, the baffle 14 on the rear side of the flow shroud 13 automatically rotates under the action of the internal and external air pressure difference. The rotation of the baffle 14 connects the flow shroud 13 with the external space, quickly balancing the internal air pressure. At this time, the torsion springs 15 at both ends of the rotating shaft of the baffle 14 deform and store energy as it rotates. After the air pressure is restored to balance, the torsion springs 15 push the baffle 14 to rotate in the opposite direction and reset through elastic restoring force, re-closing the opening of the flow shroud 13. This achieves dynamic balance of air pressure and reduces the entry of external dust through periodic opening and closing, ensuring the cleanliness of the internal airflow circulation and the long-lasting heat dissipation effect.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
