Description

Electric vehicle charger with filtering part capable of being maintained quickly
Technical Field
The utility model relates to a car battery charging outfit technical field specifically is an electric automobile charges machine with filter house that can maintain fast.
Background
The electric vehicle charger is a terminal device for providing electric energy to an electric vehicle, and the function of the electric vehicle charger is similar to that of an oiling machine in a gas station. According to the output characteristics, the charging machine is divided into a direct current charging machine and an alternating current charging pile. The direct current charger is commonly called as 'quick charging', and is a power supply device which is fixedly installed outside an electric automobile, is connected with an alternating current power grid and can provide a direct current power supply for a power battery of the off-board electric automobile. The input voltage of the direct current charger adopts three-phase four-wire AC380V +/-15%, the frequency is 50Hz, the output is adjustable direct current, and the adjustable direct current is directly used for charging a power battery of the electric automobile. Because the direct current charger adopts a three-phase four-wire system for power supply, enough power can be provided, the output voltage and current adjustment range is large, and the requirement of quick charging can be met.
A plurality of rectifier modules are generally installed in a dc charger for converting ac-dc electric energy. The loss exists in the conversion process of alternating current and direct current, the larger the output power of the rectifier module is, the larger the charging current is, the faster the charging speed is, and the larger the heat generated by components such as an inductance module, a power supply module and the like is. Currently, the efficiency of the mainstream rectifier module is nominally about 95%, and for example, a 60kW charger is used, and the heat loss of the rectifier module is 60 × 0.05 — 3 kW. In summer, the temperature in the charger easily exceeds 50 ℃ due to the influence of the ambient temperature. The working temperature range of the charger is-20 ℃ to +65 ℃, and the charger is suitable for all-weather environments. When the temperature is lower than-20 ℃ or higher than +65 ℃, the equipment stops running; the capacity reduction work is carried out at the temperature of 50-65 ℃. The rise of the temperature can cause the capacity reduction output of the charger, the service life of internal devices is shortened, and equipment failure and safety accidents can be caused under severe conditions. Therefore, in order to ensure the normal, efficient and safe operation of the charger, the heat generated inside needs to be timely discharged out of the charger. In the design of the IP protection level, the charger needs to meet the protection capability requirement of IP54 in GB4208-1993 shell protection level (IP code).
Therefore, the automobile charger needs to have a good ventilation system and a high IP protection level, the air quantity required by equipment heat dissipation needs to be fully considered, and a reasonable cooling ventilation heat dissipation system is designed according to the use environment. At present, a common method is that a front lower end and a rear upper end or a left lower end and a right upper end of a charger are respectively provided with an air inlet and an air outlet, the air inlet and the air outlet are mostly in the form of shutters or long round holes, and a water guide plate, a filter screen and dustproof cotton are additionally arranged in the air outlet so as to ensure that the charger can be waterproof and dustproof.
Patent number CN204597546U discloses an automobile charger with high-efficiency heat dissipation, which comprises a cabinet body and a door body, wherein an air inlet end is arranged at the lower part of a front panel of the door body, a dust cover is embedded in the inner wall of the door body, and the position of the dust cover corresponds to the position of the air inlet end; a rectifying module is arranged in the cabinet body, and a radiating fan is arranged on one side of the rectifying module, which is close to the air inlet end; the outer wall upper portion of the rear panel of the cabinet body is equipped with the air outlet end, and the rear panel inner wall is equipped with the windshield and is used for colleting this internal heat of cabinet body to the air exhauster of air outlet end, the utility model discloses a natural wind carries out the mode of airing exhaust from inside to outside to the ballast module, carries out abundant heat exchange with external environment, through the below one side to the rectifier module device at the machine that charges, at the built-in design wind channel that charges, adopts forced air cooling's mode, installs centrifugal fan or fan additional at the air outlet, gets rid of the heat that produces in the equipment outside.
Because the density of cold air is greater than that of hot air, the charger described above is provided with an air inlet at the lower part of the device and an air outlet at the upper part of the device. However, the air inlet is arranged at the lower part, so that dust and sundries on the ground are easily sucked into the equipment, and the air inlet is blocked; the existence of the air duct occupies the internal space of the equipment, and the arrangement and installation of components are influenced, so that the structure of the charger becomes abnormal and complicated, and the size of the charger is overlarge.
The machine that charges is outdoor product, and the operational environment of locating is comparatively abominable, in order to ensure to charge the machine inside and outside can carry out normal circulation of air, need regularly to inspect the ventilation performance of interior filter screen of equipment and dustproof cotton, in time cleans or changes. However, the existing charger needs to be opened when being maintained, the filter screen, the dustproof cotton and the corresponding mounting and fixing part are detached by using tools, and the filter screen, the dustproof cotton and the corresponding mounting and fixing part are mounted after the maintenance is finished, so that the whole maintenance process is time-consuming and labor-consuming.
