Examples
As shown in fig. 1 to 4, the invention provides a pulsating heat pipe power battery conforming heat dissipation device, which comprises a box body 1, a through hole 2, a box body narrow side face heat dissipation port 3, a box body top heat dissipation port 4, a pulsating heat pipe 5, a fixing support 6, a single battery 7 and a phase change material 8; a plurality of battery modules are arranged in the box body 1; the battery module consists of a plurality of rectangular single batteries 7, pulsating heat pipes 5 clamped between the single batteries 7 and phase-change materials 8 filled between the pulsating heat pipes 7 and the single batteries 5; the narrow side surface 3 and the top end 4 of the box body are provided with heat radiating ports; the fan is arranged on the through hole 2 on the wide side surface of the box body.

As shown in FIG. 5, the pulsating heat pipes 5 are always present in pairs, and the evaporation ends 9 of the two pulsating heat pipes are close to each other, fixed by the fixing bracket 6, and the condensation ends 10 are far away from each other.
As shown in fig. 3, the fixing support 6 is divided into a sandwich structure of the single battery 7, the pulsating heat pipe 5 and the single battery 7, and the middle gap is filled with the phase change material 8.
The evaporation end 9 absorbs heat released by the battery and transfers the heat to the condensation end 10, and the condensation section 10 penetrates through the battery pack and is matched with the narrow side heat-radiating opening 3 of the box body and the top heat-radiating opening 4 of the box body to release heat; in order to better absorb the heat released by the single batteries 7 and balance the overall temperature in the battery pack, a phase-change material 8 is filled between the evaporation end 9 and the single batteries 7; in order to avoid heat backflow, a heat insulation section is arranged between the evaporation end 9 and the condensation section 10; for more rapid and effective heat dissipation, the air flow rate needs to be increased, so that the case 1 is provided with fan holes 2, and the number of the fans to be turned on depends on the power of the battery.
The phase-change material 8 can be single material such as paraffin and the like, or composite phase-change material consisting of graphite, carbon fiber or carbon nano tube, and the melting point of the selected phase-change material is 5-20 ℃ lower than the highest working temperature allowed by the selected single battery 7 and higher than the local environment temperature; the box body 1, the narrow side heat dissipation port 3 of the box body, the top heat dissipation port 4 of the box body and the fixing support 6 are designed in an integrated mode, and the material is copper or aluminum alloy.
