Description

Vehicle-mounted magnetic type wireless charger Technical Field The utility model relates to the field of vehicle-mounted electronic equipment, in particular to a vehicle-mounted magnetic type wireless charger. Background Currently, most vehicles are provided with a wireless charger for charging electronic devices with a wireless charging function, such as mobile phones, bracelets, watches, and the like. The TEC refrigerator is arranged in part of the wireless charger and comprises a cold face and a hot face, when current passes through the TEC refrigerator, the cold face absorbs heat, the hot face releases heat, the cold face is used for cooling coils and electronic equipment in the charger, the hot face is usually connected with a radiating fin, and the heat emitted by the hot face is radiated through the radiating fin. The wireless charger with the TEC refrigerator is generally provided with a fan, under the action of the fan, wind enters from a wind gap at the top and flows through the inside of the charger and cooling fins, the cooling fins in the inside of the charger are cooled by the wind to prevent heat from accumulating in the inside of the charger, the wind gap of the existing wireless charger is always open on a charging panel, the whole appearance is not attractive, dust is easy to accumulate at the wind gap, foreign matters easily enter the charger through the wind gap to influence the normal use of the charger, and in addition, the cooling fins of the existing wireless charger are designed to achieve the purpose of improving the cooling effect, but the cooling capacity brought by the mode is very limited, and the higher and higher cooling requirements cannot be met. Disclosure of utility model In view of the above, the present utility model provides a vehicle-mounted magnetic type wireless charger with a hidden tuyere design and excellent heat dissipation effect. The utility model provides a wireless charger of on-vehicle magnetism formula of inhaling, includes from last panel, casing and the fan that sets gradually down, the top of casing is equipped with bellied boss, the panel is equipped with the confession the hole that the boss passed, the side of boss is equipped with a plurality of air intakes, inside charging assembly, TEC refrigerator and the fin of being equipped with down in proper order of casing, charging assembly installs inside the boss, charging assembly includes coil and magnetic ring, TEC refrigerator upper and lower two sides respectively with charging assembly with the fin contacts, the fin includes a plurality of ventilation opening and the heat dissipation rib that the interval set up, every ventilation opening's below all is provided with one the heat dissipation rib, the bottom of casing is equipped with the air outlet, the air outlet is located the below of heat dissipation rib, the fan is installed on the air outlet. In the technical scheme, the panel can be used as an interior trim in a vehicle, the boss passes through a hole in the panel, equipment is placed on the boss during charging, the equipment is sucked and fixed by the magnetic ring in the boss, the equipment is charged by the coil, the TEC refrigerator is positioned below the charging assembly, the cold face of the TEC refrigerator is contacted with the bottom of the charging assembly, the temperature of the charging assembly is reduced, the hot face of the TEC refrigerator is contacted with the radiating fins, generated heat is transferred to the radiating fins, in the charging process, under the air suction effect of the fan at the bottom of the shell, air flows enter the shell from the air inlet at the side face of the boss, then the air is cooled and radiated for the radiating fins through the radiating fins, and finally the air is discharged out of the shell through the air outlet at the bottom and the fan.
