Abstract
The utility model discloses an electric vehicle charger comprising a charging circuit module and a box body, wherein a base and an upper box seat are closed up to form the box body. The charging circuit module is mounted on the base and is accommodated in the box body. The top of the upper box seat is provided with a radiating fan. The radiating fan is positioned above the charging circuit module and is electrically connected with the charging circuit module. The part of the upper box seat, opposite to the radiating fan, is provided with a plurality of air inlets. The peripheral wall of the upper box seat is provided with a plurality of ventilating windows. The ventilating windows are arranged at the outer periphery of the charging circuit module. The electric vehicle charger has the advantages of simple structure and good heat dissipation effect.
Description
Technical field
The utility model relates to a kind of electric car charger, belongs to charger technical field.
Background technology
At present, along with charger use more and more extensive, the technology of charger is also at development, particularly the improvement of the radiating effect to charger is just at gradual perfection.Existing in the improved technology of charger radiating effect, Chinese patent CN2775913 discloses a kind of electric tricycle charger, its technical scheme is as follows: in charger case, two side and cover top portion have ventilating opening, fan is arranged in housing back wall, and relay is connected with the mode of the parallel connection of a module radiator or two module radiator therebetween one group relaies with a group relay with radiator; Be arranged on before fan, in the front of rectifier bridge and radiator, transformer is installed, the cold air that fan blows out is by the gap of rectifier bridge and radiator, blow to transformer, auxiliary blower is arranged on cabinet sidewall, with the wind facies mutual effect of the fan directional on rear wall, forms around eddy current, around transformer, the speed that air-flow is discharged shell slows down, and the convection current of air weakens, and radiating effect is poor.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of electric car charger is provided, and it is simple in structure, good heat dissipation effect.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of electric car charger, it comprise charging circuit module and by base, covered with upper cassette holder together with box body, charging circuit module is arranged on base and is placed in box body, the top of described upper cassette holder is provided with radiator fan, and this radiator fan is positioned at the top of charging circuit module, radiator fan and charging circuit module are electrically connected, on upper cassette holder, on the position relative with radiator fan, be provided with multiple air inlets, on the perisporium of described upper cassette holder, have multiple ventilating windows, and ventilating window is positioned at the periphery of charging circuit module.
Further, in order to reach radiating effect better, on described base, have ventilating opening, and this ventilating opening becomes relative shape to arrange with charging circuit module.
Adopted after technique scheme, the radiator fan of this electric car charger is arranged on the top of charging circuit module, by radiator fan, from air inlet, suck cold wind and directly blow to charging circuit module, then the hot blast producing after charging circuit module heat exchange, the ventilating window arranging from upper cassette holder perisporium sheds, and forms whole cross-ventilation mode, dissipation of heat is gone out, thereby improved heat dispersion, be not easy to have an accident, and its structure is also fairly simple; In addition, the ventilating opening on base also can distribute heat, has further increased heat dispersion.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric car charger of the present utility model.
Embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
As shown in Figure 1, a kind of electric car charger, it comprise charging circuit module 1 and by base 4, covered with upper cassette holder 2 together with box body, charging circuit module 1 is arranged on base 4 and is placed in box body, the top of upper cassette holder 2 is provided with radiator fan 3, and this radiator fan 3 is positioned at the top of charging circuit module 1, radiator fan 3 and charging circuit module 1 are electrically connected, on upper cassette holder 2, on the position relative with radiator fan 3, be provided with multiple air inlet 2-1, on the perisporium of upper cassette holder 2, have multiple ventilating window 2-2, and ventilating window 2-2 is positioned at the periphery of charging circuit module 1.
On base 4, have ventilating opening 4-1, and 1 one-tenth relative shape of this ventilating opening 4-1 and charging circuit module is arranged.Ventilating opening 4-1 on base 4 also can distribute heat, has further increased heat dispersion.
Operation principle of the present utility model is as follows:
The radiator fan 3 of this electric car charger is arranged on the top of charging circuit module 1, by radiator fan 3, from air inlet 2-1, suck cold wind and directly blow to charging circuit module 1, then the hot blast producing after charging circuit module 1 heat exchange, the ventilating window 2-2 arranging from upper cassette holder 2 perisporiums sheds, form whole cross-ventilation mode, dissipation of heat is gone out, thereby improved heat dispersion, be not easy to have an accident, and its structure is also fairly simple; In addition, the ventilating opening 4-1 on base 4 also can distribute heat, has further increased heat dispersion.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
