The utility model relates to a heat dissipation packaging structure, including radiating shell, first cooling tube, second cooling tube, fan assembly spare and circulation pump package, the intracavity of accommodating that is fixed in the radiating shell is accommodated to the battery, accommodates the intracavity and still is equipped with first holding chamber and the second holding chamber that is used for the dress to hold coolant respectively, first cooling tube communicates along the centre bore axial extension of battery, the entrance point and the first holding chamber of first cooling tube, the exit end and the second holding chamber intercommunication of first cooling tube, the second cooling tube is located the flow path of the air current of fan assembly spare formation, the exit end and the second holding chamber intercommunication of second cooling tube, the entrance point and the second holding chamber intercommunication of second cooling tube. So, coolant heat transferin the centre bore of battery heaies up, and the rotatory cold wind air current that produces of fan blows to the second cooling tube, and coolant cools down with the heat transfer of cold wind air current in the second cooling tube. So circulate and form a water -cooling the forced air cooling is the heat dissipation path of heat transfer constantly, and the radiating effect is good. Still provide a battery pack.
