Fig. 3 is the utility model charger and the radiator structure sketch map of battery when charged state;
Fig. 4 is the A-A cutaway view on Fig. 3.
Embodiment:
See that Fig. 1 is to shown in Figure 4: the utility model comprises battery 1, storage battery lower house 2, storage battery upper shell 10, centrifugal fan 6, charger upper shell 8, charger lower house 9; Battery 1 is installed in and constitutes a storage battery in storage battery lower house 2, the storage battery upper shell 10; Storage battery lower house 2 housings are provided with several air inlets 3 and several air outlets 5; Air inlet 3 constitutes an air duct with air outlet 5; Centrifugal fan 6 is installed in charger upper shell 8 and the charger lower house 9; Have a plurality of ventilation fences on charger upper shell 8 and the charger lower house 9, storage battery inserts the charge position of charger, and the air outlet 4 of centrifugal fan 6 is connected with air inlet 3.
Described battery 1 is more than two.
Described storage battery lower house 2, storage battery upper shell 10 are mutual fastening structure, and charger upper shell 8 is mutual fastening structure with charger lower house 9.
Battery 1 is fixed on the enclosure interior of storage battery upper shell 10, storage battery lower house 2, is preset with certain clearance as the ventilation runner between battery 1 outer wall; Lower house 2 housings are provided with several air inlets 3 and several air outlets 5, and air inlet 3 is connected to form complete internal aeration structure (like Fig. 2,3, shown in 4) with air outlet 4 respectively with air outlet 5.
Charger part is like Fig. 1, shown in 3, and charger upper shell 8 is provided with the charge in batteries position, when playing charge in batteries to the effect of battery in place; The charge position inwall is provided with air outlet 4; Because the fixedly effect of charge position of storage battery, when making storage battery put into charger to charge, its air inlet 3 aligns with air outlet 4 on the charge position inwall; And the alignment surface fit clearance is less, outwards reveals to reduce inner air; Centrifugal fan 6 in the charger is fixed on the charger upper shell 8 inner draw-in grooves; Be equipped with several air grids 11 on the housing of charger upper shell 8 and lower house 9; Be mainly charger work heat radiation, the charger air outside can be passed through air grid and entered into centrifugal fan 6 inside (as shown in Figure 3) when centrifugal fan 6 work in addition.
Storage battery begins charging; Because charge position is to the fixation of storage battery; The air inlet 3 of storage battery lower house is alignd with air outlet 4, and this moment, centrifugal fan 6 interior impellers 7 began rotation, and air can enter into centrifugal fan 6 inside through air grid 11 by the charger outside; Carry through storage battery air inlet 3 by impeller 7 again and get into internal; Air as shown in Figure 4 gets into air inlet 3 continued and flows into to position, inside battery space, and this moment, air can contact with the cylindrical outer surface of battery 1, was dispelled the heat in its surface.
Air passes preset clearance between the battery 1, is dispelled the heat in its surface.Discharge from air outlet 5 after passing the preset gap of battery 1 more respectively; When this process air flows through internal, contact with battery 1 surface, can directly battery 1 surperficial heat be taken away, the sectional area of internal ventilation runner is compared with air outlet with air inlet in addition; All less than the sectional area of air inlet and air outlet; When making air flow through the ventilation runner, make in the ventilation runner air velocity faster, and the non-direct type passage that forms at interval for the battery 1 by internal of aeration flow; Can more contact, effectively take away the internal heat with the battery surface.Can accelerate the internal heat radiation thus, can appropriateness strengthen charging current, shorten the charging interval, increase operating efficiency.
The above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
