[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0022] See also Figure 1-5 , in the figure: This embodiment is a preferred implementation of the technical solution, a new type of lithium battery insulation arrangement structure, including a positioning component for clamping and fixing lithium batteries, and a mounting frame for linearly arranging and installing a plurality of positioning components; the mounting frame includes an outer frame 1, a heat dissipation fan 2 embedded in one end of the outer frame 1, a cooling channel arranged at the bottom of the outer frame 1, ventilation slots 7 equidistantly opened on the concave surface of the outer frame 1, a liquid nitrogen bottle 9 fixed inside the cooling channel, and a cooling spiral tube 10 cyclically connected to the liquid nitrogen bottle 9;

[0023] The positioning assembly includes a guide rod 6 fixed to the concave surface of the outer frame 1, a support plate 5 located above the guide rod 6, a guide block 8 matched with the guide rod 6, and a clamp 1 3 and a clamp 2 4 fixed to the upper side of the guide block 8;

[0024] It should be noted that: in the new lithium battery insulation arrangement structure involved in the present application, a mounting frame is provided to linearly arrange and install several positioning components, so as to facilitate the fixation of different sizes, and at the same time, the mutual influence of the heat generated by the lithium battery during operation is reduced in an efficient heat dissipation manner, thereby ensuring the stable operation of the lithium battery body; specifically, the distance between the clamp 1 3 and the clamp 2 4 is adjusted to clamp and fix the lithium battery body, and according to actual usage requirements, multiple mounting frames can be installed centrally, and when the cooling fan 2 is started, the blown air flow blows along the blast channel into the cooling channel, and after the cooling treatment of the cooling channel, it is discharged from the ventilation slot 7, and then contacts the lithium battery body clamped and fixed inside the clamp 1 3 and the clamp 2 4, so as to cool its surface and accelerate its heat dissipation.

[0025] Among them Figure 1 and Figure 2As shown, the clamp 1 3 and the clamp 2 4 are L-shaped structures, and through grooves are equidistantly arranged inside the vertical branches of the clamp 1 3 and the clamp 2 4; the clamp 1 3 and the clamp 2 4 are clamped and fixed on the side of the lithium battery body, and the ends of the horizontal branches of the clamp 1 3 and the clamp 2 4 are arranged in a bevel shape;

[0026] It should be noted that after the clamps 1 3 and 2 4 fix the lithium battery body, the heat generated by the operation of the lithium battery body is conducted to the clamps 1 3 and 2 4. The through grooves inside the vertical branches of the clamps 1 3 and 2 4 make the contact surface between the clamps 1 3 and 2 4 and the air larger, and the heat dissipation effect is better, thereby reducing the mutual influence of the heat generated by the adjacent lithium battery bodies during operation. The beveled setting of the horizontal branches of the clamps 1 3 and 2 4 is used to facilitate the clamping of the lithium battery body.

[0027] Among them Figure 2 As shown, a cover plate is provided at the opening of the cooling channel, and the cover plate is fixed to the bottom opening of the outer frame 1; a blast channel for installing a cooling fan 2 is provided inside the protrusion at one end of the outer frame 1, and the blast channel is communicated with the cooling channel; the ventilation slot 7 is communicated with the cooling channel, and the ventilation slot 7 is located directly below the clamp 1 3 and the clamp 2 4;

[0028] It should be noted that: when the cooling fan 2 is started, the airflow blown out is blown into the cooling channel along the blast channel, and after being cooled in the cooling channel, it is discharged from the ventilation slot 7, and then comes into contact with the lithium battery body clamped and fixed inside the clamps 1 3 and 2 4, thereby cooling its surface and accelerating its heat dissipation.

[0029] Among them Figure 3 As shown, a knob is fixed on the side of the guide block 8, and the threaded end of the knob is in contact with the peripheral side of the guide rod 6;

[0030] It should be noted that the knob is used to fix the position of the guide block 8 relative to the guide rod 6, so that the positions of the clamp 1 3 and the clamp 2 4 are fixed, thereby achieving the clamping and fixing of the lithium battery body. Embodiment 2

[0031] Among them Figure 5As shown, a protective pad structure is embedded in the inner wall of the vertical branches of the clamp 1 3 and the clamp 2 4. When the clamp 1 3 and the clamp 2 4 are clamped and fixed to the lithium battery body, the protective pad is clamped between the side of the lithium battery body and the vertical branches of the clamp 1 3 and the clamp 2 4, which is used to improve the friction effect of the clamp 1 3 and the clamp 2 4 on the lithium battery body, improve the clamping stability of the lithium battery body, and also protect the lithium battery body. The shape of the protective pad used changes according to the different shapes of the lithium battery body. This application takes a rectangular lithium battery body as an example, and the protective pad used is a flat rectangular structure. If it is a clamping protection for a cylindrical lithium battery body, the protective pad is replaced with an arc-shaped protruding structure to cooperate with the surrounding side of the cylindrical lithium battery body. The structural setting of the protective pad is a currently more common protection and auxiliary fixing structure, and no further restrictive description is made here.
