[0024] The utility model discloses through reasonable layout circuit board 2, inner heat dissipation plate 3 and heat dissipation fan 4 etc. component, make the whole measurement and charge-discharge module's structure compact and high efficiency, reduce the volume of measurement and charge-discharge module, in addition still make the circuit in the heat dissipation shell 1 obtain good electric shielding effect and improve the anti-interference ability of the precision detection circuit of measurement and charge-discharge module.

[0025] As one of the preferred embodiments of the utility model, Figure 2 And Figure 4 As shown, the front end lower surface of the circuit board 2 is provided with a front contact column 21 connected in an electrically conductive manner, the front end lower surface of the circuit board 2 is provided with a rear contact column 23 connected in an electrically conductive manner, the front end of the bottom surface of the heat dissipation shell 1 is provided with a front end notch 16 at the corresponding position of the front contact column 21, and the rear end of the bottom surface of the heat dissipation shell 1 is provided with a rear end notch 17 at the corresponding position of the rear contact column 23.

[0026] The front contact column 21 and the rear contact column 23 serve as the electrically conductive connection points between the circuit board 2 and external equipment or power supply, and play an important role in signal transmission and current transmission. They are firmly fixed on the front end lower surface of the circuit board 2 through welding or other connection methods, ensuring the electrical connection stability and reliability of the circuit board 2.

[0027] The front end notch 16 and the rear end notch 17 are arranged at the front end and the rear end of the bottom surface of the heat dissipation shell 1 and correspond to the front contact column 21 and the rear contact column 23 respectively, so that the external contact column socket can be conveniently connected with the contact column on the circuit board 2 through the notch without disassembling the whole heat dissipation shell 1. The design not only simplifies the connection process, but also improves the convenience and efficiency of the connection.

[0028] As one of the preferred embodiments of the utility model, Figure 3 and Figure 5 As shown in the drawings, the mounting clamping groove 12 extending along the length direction of the heat dissipation shell 1 and matched with the two side edges of the circuit board 2 in the width direction is arranged on the inner wall of the left and right sides of the heat dissipation shell 1, and the two side edges of the circuit board 2 in the width direction are connected with the inner wall of the heat dissipation shell 1 through the clamping of the mounting clamping groove 12.

[0029] The design of the mounting clamping groove 12 enables the circuit board 2 to be firmly fixed inside the heat dissipation shell 1, the mounting clamping groove 12 extends along the length direction of the heat dissipation shell 1 and is tightly matched with the two side edges of the circuit board 2 in the width direction, the circuit board 2 is stably mounted on the inner wall of the heat dissipation shell 1 through the clamping mode, which can effectively prevent the circuit board 2 from shaking or displacing during the working process, thereby ensuring the accuracy and stability of the measurement and charge-discharge module, in addition, the mounting clamping groove 12 is not only used for fixing the circuit board 2, but also can enhance the structural strength of the whole measurement and charge-discharge module, when the circuit board 2 is tightly fixed inside the heat dissipation shell 1, it will form an integral structure with the heat dissipation shell 1, thereby improving the impact resistance and shock resistance of the module.

[0030] As one of the preferred embodiments of the utility model, Figure 1 , Figure 4 and Figure 5 As shown in the drawings, the first fins 11 are equidistantly arranged on the top surface of the heat dissipation shell 1 in the width direction of the heat dissipation shell 1, the second fins 31 are arranged on the upper and lower surfaces of the inner heat dissipation plate 3 respectively, and the second fins 31 are equidistantly arranged in the width direction of the inner heat dissipation plate 3.

[0031] The equidistant arrangement of the first fins 11 on the top surface of the heat dissipation shell 1 effectively increases the heat dissipation area, the fins as the medium of heat exchange can more quickly conduct the heat generated inside the heat dissipation shell 1 to the external environment, which not only improves the heat dissipation efficiency, but also helps to maintain the uniformity of the temperature inside the heat dissipation shell 1.

[0032] Second fins 31 are respectively arranged on the upper and lower surfaces of the inner heat dissipation plate 3, and are equidistantly arranged along the width direction thereof, and also play a role of enhancing the heat dissipation efficiency.

[0033] By equidistantly arranging the fins, uniform distribution of heat in the heat dissipation structure can be ensured, thereby avoiding the problem of local overheating caused by heat concentration, improving the overall stability and reliability of the heat dissipation structure, and meanwhile, the equidistantly arranged fins can also reduce the resistance in the heat dissipation process, so that heat can more smoothly pass through the heat dissipation structure, which helps to reduce the power consumption of the heat dissipation fan 4 and improve the energy efficiency ratio of the whole module.

[0034] As one of the preferred embodiments of the utility model, as shown in Figure 3 and Figure 4 , the left and right side edges of the upper surface of the circuit board 2 are symmetrically provided with vertical plates 22, the left and right sides of the inner heat dissipation plate 3 are connected with connecting plates 32 corresponding to the positions of the vertical plates 22, and the vertical plates 22 are connected with the corresponding connecting plates 32 through connecting pieces.

[0035] The vertical plates 22 are symmetrically arranged on the left and right side edges of the upper surface of the circuit board 2, and the left and right sides of the inner heat dissipation plate 3 are connected with the connecting plates 32 corresponding to the positions of the vertical plates 22. This design enables the inner heat dissipation plate 3 to be tightly connected with the vertical plates 22 and the connecting plates 32 through connecting pieces (such as bolts), thereby realizing stable fixation. The above-mentioned fixation mode not only ensures the position stability of the inner heat dissipation plate 3 above the circuit board 2, but also helps to improve the reliability and durability of the whole heat dissipation structure.

[0036] As one of the preferred embodiments of the utility model, as shown in Figure 1 , the four corner positions of the heat dissipation fan 4 are respectively provided with fixed screws 41 threadedly connected with the front end side wall of the heat dissipation shell 1, and the heat dissipation fan 4 is installed on the front end side wall of the heat dissipation shell 1 through the fixed screws 41.

[0037] As an important heat dissipation component in the compact rechargeable battery module balancing instrument measurement and charge-discharge module, the heat dissipation fan 4 can be tightly and firmly installed on the front end side wall of the heat dissipation shell 1 through the fixed screws 41 arranged at the four corner positions, which not only ensures the stability of the heat dissipation fan 4 in the working process, but also helps to prevent loosening or falling off caused by vibration or external impact.

[0038] The design of the fixing screw 41 connected by threads makes the installation and dismounting process of the heat dissipation fan 4 simple and fast, and the user only needs to align the heat dissipation fan 4 with the mounting holes on the front end side wall of the heat dissipation shell 1, and then uses a screwdriver or other tools to screw the fixing screw 41 in to realize fixation. Similarly, when the heat dissipation fan 4 needs to be dismounted, only the fixing screw 41 needs to be unscrewed and the fan and the heat dissipation shell 1 need to be separated, thereby reducing the maintenance cost and time, and improving the availability and flexibility of the equipment.

[0039] As one of the preferred embodiments of the utility model, as shown in Figure 5 The left and right side edges of the bottom surface of the heat dissipation shell 1 are provided with sliding clamping grooves 13 for slidingly fixing the heat dissipation shell 1.

[0040] The design of the sliding clamping grooves 13 provides an additional fixing mechanism for the entire measurement and charge-discharge module, greatly facilitating the process of installing it into the box body of the battery module equalizer, and specifically, before placing the battery module equalizer measurement and charge-discharge module into the box body of the battery module equalizer, there is a preliminary step of assembling the measurement and charge-discharge module on an assembly base plate 14, and the assembly base plate 14 is provided with a plurality of sliding clamping strips 15 on the surface, which can be slidably matched with the sliding clamping grooves 13 on the bottom of the heat dissipation shell 1 of the measurement and charge-discharge module.

[0041] When operating, the user only needs to align and slide the sliding clamping grooves 13 on the bottom surface of the heat dissipation shell 1 with the sliding clamping strips 15 on the assembly base plate 14, and the multiple battery module equalizer measurement and charge-discharge modules can be easily and stably fixed on the assembly base plate 14. Such a design not only realizes modular installation, but also greatly promotes the regular arrangement of multiple battery module equalizer measurement and charge-discharge modules in the box body of the battery module equalizer, thereby more effectively utilizing the space in the box body.

[0042] Overall, the cooperation mechanism of the sliding clamping grooves 13 and the sliding clamping strips 15 not only enhances the fixing stability of the measurement and charge-discharge module, but also optimizes the installation process of the module in the box body of the battery module equalizer, and improves the space utilization efficiency.

[0043] The above is only a preferred embodiment of the utility model, and it should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the utility model, and these improvements and refinements should also be considered as the protection scope of the utility model.
