Description

Lateral blowing radiator and wireless charger

The technical field is as follows:

the invention belongs to the technical field of electronic products, and particularly relates to a lateral blowing radiator and a wireless charger.

Background art:

along with popularization and application of a wireless charging technology in various electric appliances such as mobile phones, computers, intelligent watches, earphones, electric toothbrushes, electric tools and the like, great convenience and interface compatibility are brought to work and life of people.

The desktop type wireless charger or the vehicle-mounted type wireless charger with single function has small charging power, low charging speed and no heat dissipation function, and the shell of the mobile phone can be hot after the charging time is long, so that the game speed is blocked, the navigation program is quitted by thermal protection, the mobile phone is halted and restarted, the battery of the equipment of the mobile phone is invisibly damaged, and the service life of the electric appliance is shortened. For the electrical appliances with ever increasing wireless charging power requirements in the future, a charger which can realize high-efficiency wireless charging and has a good heat dissipation effect is urgently needed.

The existing single-function radiator for blowing air up and down by using an electronic fan does not adopt a semiconductor refrigeration piece, so that the radiating effect is not obvious, and the radiator does not greatly help consumers who like playing mobile games and navigating by using mobile phones in summer.

The existing radiator which only adopts the semiconductor refrigerating sheet can provide a radiating effect for the mobile phone, but the buckle type fixing mode adopted by the radiator and the mobile phone is not convenient for assembling, disassembling and using angle adjustment, especially for large-screen mobile phones and tablet computers. Even if the radiator with partial design has the magnetic attraction fixing function of the strong magnet, but does not have the wireless charging function, if the mobile phone is charged by the data line while radiating, two lines are interwoven for use, one line charges the mobile phone and the other line supplies power to the radiator, and the use is still inconvenient.

The existing wireless charger with the semiconductor refrigeration function still adopts a common electronic fan, the thickness of a wireless charger product formed by stacking and placing the fan and a radiating fin together is too thick, most of the wireless charger product is cylindrical, and when the wireless charger in a working state (air enters from the lower part and exits from the upper part) and blowing up and down by the fan is horizontally placed on a desktop, a main air inlet of the wireless charger product is directly blocked, so that the wireless charger product with the design is only suitable for being placed on the side or suspended by a bracket and is not suitable for being used as a charger for being placed on a desktop flat plate; in addition, because the mobile phone is a cylinder, the contact surface of the mobile phone is small, and the mobile phone cannot be stably supported when the mobile phone is used as an on-board charger.

If the electronic fan blowing air up and down or the heat dissipation module with the semiconductor refrigeration sheet and the charging transmitting coil are simply horizontally placed, the heating area and the refrigeration area respectively correspond to different parts of the mobile phone, the shell of the mobile phone is not in heat conduction timely, and the heat dissipation effect is still greatly reduced.

In addition, the design of the heat dissipation adopting the up-and-down blowing of the fan has the advantages that the air inlet and the air outlet are too close, cold and hot air does not have a separate channel in the heat dissipation fin, the cold and hot air are disturbed back and forth from top to bottom and from left to right in the cavity of the heat dissipation fin, the heat exchange is disordered, the convection is insufficient, and the heat dissipation efficiency is poor.

When a mobile phone is charged or a radiator is used, a microphone, an earphone, data storage and copy, video recording, live broadcasting and other functions are often needed. If the wireless charger is not docking station capable, additional docking stations may be required to implement the above-described synchronization requirements or to enable Bluetooth technology or other wireless communication protocols. The invention provides a method for connecting a mobile phone with a docking station interface configured by the mobile phone by a data line during wireless charging, and other interfaces of the docking station can provide more convenience for the connection of the mobile phone and other equipment, thereby not only solving the problems of signal delay, poor signal quality and unstable communication when a Bluetooth technology or other wireless communication protocols are adopted, but also providing interfaces for mobile storage such as a U disk and the like for the shortage of the storage space of the mobile phone. The heat dissipation type wireless charger equipped with the docking station is more suitable for consumers with higher requirements on the multifunction and convenience of electronic products.

The multifunctional integrated wireless charger with the non-flat shell design has little space left for an integrated circuit board, and a product is not suitable for being provided with a plurality of power supplies or data interfaces, cannot be used in parallel, and is not suitable for being used as a docking station by utilizing a cavity and the side wall of the product; even if the multifunctional integrated wireless charger adopting the flat shell design exists, the directional heat dissipation groove design of the heat dissipation fins and the directional blowing, large air quantity and atmospheric pressure characteristics of the blowing device are not adopted, so that the problems that the product airflow flowing area is short, the ventilation effect is poor, the wind power is small or the noise is large, the wireless charger is not suitable for two-in-one or three-in-one wireless charger, and various defects and shortcomings cannot be well solved are caused.

The design has better effect than a pure radiator which is blown by an electronic fan to dissipate heat, and the surface temperature of the product can be quickly reduced to zero from the room temperature within a few seconds after the switch of the semiconductor refrigeration piece is started.
