[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5 As shown, a detachable square battery module includes a battery module composed of multiple square batteries, a conductive connecting piece installed on the top of the square battery and fixed angle steels installed on both sides of the bottom of the square battery for fixing the square battery, a bow-shaped heat dissipation tube 1 is arranged on the outside of the square battery, the tube body of the bow-shaped heat dissipation tube 1 is bent to form multiple battery slots 101, the square battery and the inner wall of the battery slot 101 are inserted and connected, and a fan 2 is connected to the tube opening at one end of the bow-shaped heat dissipation tube 1.

[0023] like Figure 1 As shown, a detachable square battery module in the utility model is similar to the existing square battery module structure, such as a square battery module disclosed in the patent with announcement number CN106531914A. The main improvement of the utility model is that the temperature of the battery can be maintained within a safe range, thereby reducing the safety risks of battery overheating, short circuit, etc. Figures 1 to 5 As shown, when a detachable square battery module in the utility model is in use, a conductive connecting piece is installed on the top of each square battery for connecting the batteries in series and parallel, and fixed angle steels are installed on both sides of the bottom of the square battery for fixing and supporting the battery module to ensure the stability and safety of the battery. A bow-shaped heat dissipation tube 1 is arranged on the outside of the square battery. The bow-shaped design can increase the heat dissipation area and improve the heat dissipation efficiency. The tube body of the bow-shaped heat dissipation tube 1 is bent to form a plurality of battery slots 101. The size of each battery slot 101 matches the size of the square battery, so that the square battery can be tightly inserted into the battery slot 101. One end of the bow-shaped heat dissipation tube 1 is connected to a fan 2. The fan 2 generates airflow by rotating to take away the heat in the heat dissipation tube, thereby achieving rapid heat dissipation.

[0024] like Figures 2 to 3 As shown, a stop plate 3 is fixedly connected to the battery slot 101 on the side opposite to the conductive connecting sheet.

[0025] Specifically, the main function of the plate 3 is to support the square battery, ensure the stable position of the battery in the battery slot 101, and prevent the battery from shifting or falling off under vibration or impact. The plate 3 is made of hard plastic to ensure that it can withstand the weight of the battery and external pressure.

[0026] like Figure 4 As shown, a plurality of air holes 301 are provided on the surface of the abutment plate 3 .

[0027] Specifically, the main function of setting the vent hole 301 is to increase the air permeability of the plate 3, which is beneficial to the heat dissipation inside the battery module. When the battery generates heat during the charging and discharging process, the heat can be dissipated to the external environment through the vent hole 301, thereby effectively reducing the temperature of the battery module and improving the performance and safety of the battery.

[0028] like Figure 3 As shown, the abutment plates 3 in the plurality of battery slots 101 are horizontally aligned.

[0029] Specifically, through this arrangement, when multiple abutment plates 3 are horizontally aligned in the battery slot 101, they can jointly form a stable support plane to ensure the stable position of the square battery in the module. The top of the square battery and the conductive connecting piece are kept in a fixed connection position, ensuring the stable connection between the conductive connecting piece and the adjacent battery or other components of the module, reducing performance degradation or safety hazards caused by poor connection.

[0030] like Figure 3 As shown, the inner walls of both sides of the battery slot 101 are provided with thermal conductive pads 4 which are closely connected to the outer sides of the square batteries.

[0031] Specifically, the main function of setting up the thermal pad 4 is to enhance the heat conduction efficiency between the square battery and the battery slot 101. When the square battery generates heat during operation, the thermal pad 4 can quickly conduct the heat from the battery to the heat dissipation structure of the battery slot 101, thereby effectively reducing the battery temperature and improving the battery's operating efficiency and safety.

[0032] like Figure 5 As shown, a filter screen 5 is installed at the tail of the bow-shaped heat dissipation pipe 1.

[0033] Specifically, through this arrangement, the filter 5 is installed at the tail of the bow-shaped heat dissipation pipe 1, and its main function is to filter out impurities and dust entering the heat dissipation pipe to prevent these substances from clogging the inside of the heat dissipation pipe and affecting the heat dissipation effect.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
