Technical Field

[0001] The invention relates to the technical field of battery core brackets, and in particular to a battery core bracket with a heat dissipation function. Background Art

[0002] A cell holder is a device composed of mechanical components used to support and fix battery cells. Its main function is to ensure that the battery can operate stably during use and prevent the cell from displacement, shaking, collision or short circuit during transportation, installation, assembly and use, thereby ensuring the structural stability and safety of the battery.

[0003] Existing battery holders are generally designed with a certain heat dissipation structure to help the battery dissipate heat during operation, reduce battery temperature, and improve battery performance and life. However, most heat dissipation structures dissipate heat through the material itself. When operating in a high temperature environment, the heat dissipation effect achieved by relying solely on the material itself will be poor, which will affect the chemical reaction inside the battery, resulting in a decrease in battery performance, a decrease in battery capacity, an increase in internal resistance, and a decrease in charge and discharge efficiency. In addition, some staff will install electrical equipment, such as fans, to dissipate heat, but more external electrical equipment will increase energy consumption. At the same time, external electrical equipment may generate electromagnetic interference, affecting the normal operation of the battery holder and its surrounding equipment.

[0018] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0019] Embodiments of the present invention: Please refer to Figures 1 to 8 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a battery cell bracket with heat dissipation function, including a bracket body 1, and also including: an alarm protection mechanism and a heat dissipation protection mechanism, the heat dissipation protection mechanism is located above the alarm protection mechanism, and the heat dissipation protection mechanism is driven by the alarm protection mechanism; The alarm protection mechanism is used to send out an alarm signal when the bracket body 1 is overheated, and the heat dissipation protection mechanism is used to dissipate heat for the bracket body 1.

[0020] In the prior art, the battery holder is generally designed to have a certain heat dissipation structure to help the battery dissipate heat during operation, reduce the battery temperature, and improve the performance and life of the battery. However, the heat dissipation structure mostly dissipates heat through the material itself. When operating in a high temperature environment, the heat dissipation effect achieved by relying solely on the material itself will be poor, so that the chemical reaction inside the battery will be affected, resulting in a decrease in battery performance, a decrease in battery capacity, an increase in internal resistance, and a decrease in charging and discharging efficiency. Compared with the prior art, the implementation of this embodiment, through the setting of the alarm protection mechanism, through the alarm signal issued by the alarm 209, the staff can know the problem before the overheating situation becomes serious, which helps to avoid potential failures or damage, thereby extending the service life of the equipment and system. At the same time, the air pressure change caused by overheating is used to drive the piston 203 to slide, thereby driving the first electrical contact 206 to contact the second electrical contact 208. Compared with the prior art, no sensor or other control is required, which saves power resources and thus saves detection costs.

[0021] For further examples, please refer to Figures 1 to 8 As shown: The heat dissipation protection mechanism includes a push block 301, which is fixedly connected to the top of the sliding link 205, one side of the push block 301 is arranged in an arc shape, a push rod 302 is slidably connected to the top of the fixed plate 207, the bottom of the push rod 302 is arranged in an arc shape, a return spring 303 is fixedly connected between the push rod 302 and the fixed plate 207, a connecting rod 304 is fixedly connected to the top of the return spring 303, a liquid heat dissipation pipe 305 is fixedly connected to the outside of the bracket body 1, an external circulation pipe is arranged on one side of the liquid heat dissipation pipe 305, an external pipe 306 is fixedly connected to one side of the liquid heat dissipation pipe 305, a valve plate is rotatably connected to the inner surface of the lower end of the external pipe 306, a valve stem 307 is rotatably connected to the lower end of the external pipe 306, the valve stem 307 is fixedly connected to the valve plate, and the valve The outer surface of the rod 307 is in contact with one side of the connecting rod 304, and a sealing box 308 is fixedly connected to one side of the external tube 306. The external tube 306 is connected to the sealing box 308, and a water wheel 309 is rotatably connected inside the sealing box 308. One side of the water wheel 309 is located in the external tube 306, and an air outlet pipe 311 is fixedly connected to one side of the water wheel 309. A rotating fan wheel 310 is rotatably connected inside the air outlet pipe 311. One end of the rotating fan wheel 310 passes through the air outlet pipe 311 and the sealing box 308, and one end of the rotating fan wheel 310 is fixedly connected to the water wheel 309. A heat dissipation pipe 312 is fixedly connected to the top of the outer wall of the bracket body 1, and the air outlet pipe 311 is fixedly connected to the heat dissipation pipe 312, and air outlet holes are fixedly connected to the bottom of the outer surface of the heat dissipation pipe 312 at equal intervals.

[0022] In the implementation of this embodiment, by setting the heat dissipation protection mechanism, after the alarm protection mechanism triggers the alarm, before the staff arrives, the power generated by the air pressure can drive the valve stem 307 to open, so that the coolant enters the liquid heat dissipation pipe 305 and cools the bracket body 1. At the same time, the kinetic energy generated by the flow of the coolant is used to drive the water wheel 309 and the rotating fan wheel 310 to rotate, thereby generating airflow, and the bracket body 1 is further cooled by the generated airflow. Compared with the prior art, there is no need to install additional power facilities such as fans, further saving the cooling and heat dissipation cost, improving the safety of the bracket body 1 when in use, and reducing the risk of safety accidents; In addition, through the coordinated setting of the heat dissipation protection mechanism and the alarm protection mechanism, the air flow pressure difference generated by the overheating of the bracket body 1 and the kinetic energy generated by the flow of coolant are used as driving force, and the air flow pressure difference and coolant flow generated by overheating are utilized to form an active heat dissipation effect. This heat dissipation method is more efficient than natural heat dissipation, and can reduce the temperature of the battery holder and the battery cell more quickly, and utilizes physical changes to trigger alarms and heat dissipation. Therefore, compared with complex electronic systems, it may have a simpler maintenance process, which helps to reduce maintenance costs and extend the service life of the equipment. At the same time, it also reduces the interference of external electronic devices on the bracket body and the battery cell, and improves the stability and safety of the battery holder during use.

[0023] Everything in the above example works like this: In the initial state: the liquid outlet end of the external liquid storage tank is fixedly connected to one end of the external pipe 306, and the external circulation pipe is connected to the external receiving header.

[0024] The following is the working process of the alarm protection agency: When the bracket body 1 is overheated, the heat conducting member 202 will conduct the heat of the bracket body 1, so that the heat conducting member 202 also becomes hotter, and then the sealed space between the piston 203, the detection tube body 201 and the bracket body 1 becomes hotter, so that the air pressure in the space increases, and the increased air pressure pushes the piston 203 to move in the direction of the compression spring 204, the compression spring 204 is compressed, and at the same time, the piston 203 drives the sliding link 205 to slide at the same time, and the sliding link 205 drives the first electrical contact 206 Approach the second electrical contact 208 so that the second electrical contact 208 contacts the first electrical contact 206. Since the first electrical contact 206 and the second electrical contact 208 are electrically connected to control the opening and closing of the alarm 209, when the first electrical contact 206 and the second electrical contact 208 contact, the alarm 209 is activated, so that the alarm 209 sends an alarm signal. Finally, the staff can know that the bracket body 1 is overheated through the alarm signal sent by the alarm 209, and then conduct inspection and processing; By setting the alarm protection mechanism, the staff can know the problem before the overheating situation becomes serious through the alarm signal issued by the alarm 209, which helps to avoid potential failures or damages, thereby extending the service life of the equipment and system. At the same time, the air pressure change generated by overheating is used to drive the piston 203 to slide, thereby driving the first electrical contact 206 to contact the second electrical contact 208. Compared with the prior art, no sensor or other control is required, which saves power resources and thus saves detection costs; Please refer to the above working process Figures 1 to 8 .

[0025] The following is the working process of the heat dissipation protection mechanism: When the alarm protection mechanism triggers the alarm, the sliding link 205 moves to drive the first electrical contact 206 and the second electrical contact 208 to contact, and the push block 301 will also move in the direction of the push rod 302, and then the push block 301 pushes the push rod 302 arc surface through the push block 301 arc surface, so that the push rod 302 moves upward, and the return spring 303 is stretched, thereby driving the connecting rod 304 to move upward. When the connecting rod 304 moves upward, one side of the connecting rod 304 abuts against the outer surface of the valve stem 307, and then the friction force generated by the abutment drives the valve stem 307 to rotate, so that the valve stem 307 drives the valve plate inside the external pipe 306 to rotate, and the external pipe 306 is opened, and the coolant in the external liquid storage tank enters the external pipe 306, and enters the liquid heat dissipation pipe 305 through the external pipe 306. By flowing in the liquid heat dissipation pipe 305, the heat of the outer surface of the bracket body 1 can be taken away, and then it is collected by the external receiving collection box through the external circulation pipe, and can be reused; In addition, when the coolant flows in the external pipe 306, it can drive the water wheel 309 to rotate, and the rotation of the water wheel 309 drives the rotating fan wheel 310 to rotate. The rotation of the rotating fan wheel 310 can generate airflow, and enter the wind heat dissipation pipe 312 through the air outlet pipe 311, and finally blow out from the air outlet hole at the bottom of the wind heat dissipation pipe 312, acting on the outer surface of the bracket body 1, thereby further improving the heat exchange effect between the bracket body 1 and the outside world; By setting the heat dissipation protection mechanism, after the alarm protection mechanism triggers the alarm, before the staff arrives, the power generated by the air pressure can drive the valve stem 307 to open, so that the coolant enters the liquid heat dissipation pipe 305 and cools the bracket body 1. At the same time, the kinetic energy generated by the flow of the coolant is used to drive the water wheel 309 and the rotating fan wheel 310 to rotate, thereby generating airflow, and the bracket body 1 is further cooled by the generated airflow. Compared with the prior art, there is no need to install additional power facilities such as fans, further saving the cooling and heat dissipation cost, improving the safety of the bracket body 1 when in use, and reducing the risk of safety accidents; In addition, through the coordinated setting of the heat dissipation protection mechanism and the alarm protection mechanism, the air flow pressure difference generated by the overheating of the bracket body 1 and the kinetic energy generated by the flow of coolant are used as driving force, and the air flow pressure difference and coolant flow generated by overheating are utilized to form an active heat dissipation effect. The above heat dissipation method is more efficient than natural heat dissipation, and can reduce the temperature of the battery cell bracket and the battery cell more quickly, and utilizes physical changes to trigger alarms and heat dissipation. Therefore, compared with complex electronic systems, it may have a simpler maintenance process, which helps to reduce maintenance costs and extend the service life of the equipment.
