Specifically, a in fig. 6 is a schematic side view of the structure of the loop heat pipe system; FIG. 6B is a schematic diagram of a top view of a loop heat pipe system; fig. 6C is a schematic top view of another loop heat pipe system structure.

Referring to A, B, C in fig. 6, the evaporation end 200 specifically includes a U-shaped heat pipe 2001, the U-shaped heat pipe 2001 is used for containing a refrigerant, further, a capillary tube (not shown in fig. 6) is disposed in the U-shaped heat pipe 2001, the battery module 100 is placed in a U-shaped groove of the U-shaped heat pipe 2001, the battery module 100 is composed of a plurality of batteries 1001 connected in series in sequence, and the battery module 100 is connected to different polarity ends of adjacent batteries through a battery connecting sheet 1002. It should be noted that: the structure diagram in fig. 6 is only a schematic illustration, and the specific number of the batteries connected in series, the size of the loop heat pipe system, and the structural form of the loop heat pipe system under different viewing angles are not limited in particular.

Specifically, the heat dissipation principle of the loop heat pipe system is as follows: the U-shaped heat pipe 2001 contains a refrigerant, the battery module 100 is placed in a U-shaped groove of the U-shaped heat pipe 2001, when the battery module 100 is in an operating state and temperature control is required, the refrigerant contained in the U-shaped heat pipe 2001 evaporates after absorbing heat emitted by the battery module to generate pressure difference, pressure drive is generated based on the pressure difference, so that the refrigerant in the U-shaped heat pipe 2001 flows to the condensation heat pipe 3003 in the condensation end 300 along a capillary tube arranged in the U-shaped heat pipe 2001 to be condensed, and heat generated by the operation of the battery module 100 is taken away through the fin 3001 and the condensation end fan 3002, so that the temperature of the battery module 100 is regulated.
