Problems solved by technology
Because the charger generates heat during charging, cooling teeth, cooling holes and cooling fans are usually provided on the outer surface of the charger for heat dissipation. This method has poor heat dissipation performance. After a period of use, the circuit board of the charger It will accumulate a lot of dust, which greatly shortens the service life of circuit components, and it is easy to cause short circuit, causing safety hazards, and the existing chargers cannot solve the waterproof and moisture-proof problem, mainly because the heat dissipation holes will make water easy to enter to the inside of the charger, causing an internal short circuit and affecting the charging performance

Embodiment Construction
[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0018] like Figure 1 to Figure 5 As shown, a heat dissipation structure for an electric vehicle charger includes an upper cover 1, an L-shaped side cover 2, a middle partition 3, a cooling fan 4, and a bottom partition 5. The upper cover 1 is in a U-shaped structure, and the The front and rear sides of the upper cover 1 are provided with external cooling teeth 1a. There are two L-shaped side covers 2, and the two L-shaped side covers 2 are symmetrically installed on the left end and the right end of the upper cover 1 respectively. The bottom of the upper cover 1 is blocked by a horizontally placed middle partition 3, and the left end and right end of the middle partition 3 are respectively installed on the two L-shaped side covers 2 by screws. The upper cover 1, the middle The partiti...

The invention relates to a heat dissipation structure for an electric motor car charger. The heat dissipation structure comprises an upper cover, two L-shaped side covers, a middle partition, a cooling fan, and a bottom partition, wherein the L-shaped side covers are symmetrically mounted at the left end and the right end of the upper cover respectively; the lower part of the upper cover is blocked by the middle partition; the left and right ends of the middle partition are correspondingly mounted on the L-shaped side covers through bolts; the upper cover, the middle partition and the L-shaped side covers define a closed space; a first air chute is formed in the left part of the middle partition; a second air chute is formed in the right part of the middle partition; the first air chute and the second air chute are communicated with the closed space; the cooling fan is arranged under the second air chute, and connected with the middle partition; the bottom partition is arranged under the middle partition. The heat dissipation structure has the advantages that the structural design is reasonable; the assembly and the use are convenient; the production cost is low; the functions of heat dissipation and damp prevention can be realized; normal work and normal use of a circumscribed circuit board and the charger are guaranteed.
Description
technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a heat dissipation structure for an electric vehicle charger. Background technique [0002] Due to the non-renewable nature of gasoline and diesel, with the continuous popularization of automobiles, oil is becoming more and more depleted, and electric vehicles, as new energy vehicles, are gradually recognized by people. As a new energy vehicle, it is deeply loved by people. In order to ensure the normal use of the electric vehicle, it is necessary to charge the electric vehicle in time when the electric vehicle lacks electric energy, that is, to use the charger to connect the external power supply to charge the battery in the electric vehicle. Because the charger generates heat during charging, cooling teeth, cooling holes and cooling fans are usually provided on the outer surface of the charger for heat dissipation. This method has poor heat dissipation perfor...
