Wherein, among Fig. 1-Fig. 2:
Embodiment
Core of the present utility model provides a kind of Vehicular charger and air-cooled structure thereof, can improve the radiating efficiency of Vehicular charger, guarantees the service behaviour of Vehicular charger.
In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the structural representation of Vehicular charger in a kind of embodiment provided by the utility model; Fig. 2 is the structural representation of Vehicular charger partial structurtes shown in Figure 1.
In this embodiment, be fixedly installed air-cooled structure on the base plate 2 of Vehicular charger body 1, air-cooled structure comprises heat radiation gear piece 3 and blower fan 4, a plurality of heat radiation gear pieces 3 distribute centered by blower fan 4 ringwise, and heat radiation gear piece 3 is connected with blower fan 4.
When assembling, can first heat radiation gear piece 3 be arranged ringwise, in the center mounting groove is set, blower fan 4 is bolted be arranged at mounting groove, when mounted, guarantee that the center of blower fan 4 and the center of Vehicular charger body 1 coincide.
So arrange, blower fan 4 can make hot-air Vehicular charger body 1 in via the gear piece 3 that dispels the heat when rotating, finally enter external environment condition by blower fan 4, because heat radiation gear piece 3 distributes ringwise centered by blower fan 4 and is connected with blower fan 4, hot-air can be along being moved by heat radiation gear piece 3 formed ring-shaped peripheries, can Homogeneouslly-radiating.
Compared with prior art, heat radiation gear piece 3 distributes ringwise and can avoid the inhomogeneous problem of heat radiation that can only move and cause to cooling blower from the two ends of Vehicular charger owing to the hot-air that is arranged in parallel, simultaneously, heat radiation gear piece 3 distributes ringwise and has enlarged area of dissipation, can improve the radiating efficiency of Vehicular charger, and then guarantee the service behaviour of Vehicular charger.
In addition, with the center of blower fan 4 and the center superposition of Vehicular charger body 1, can avoid causing dispelling the heat inhomogeneous owing to position that blower fan 4 is arranged at other, so, can guarantee the uniformity of Vehicular charger body 1 heat radiation.
