Description

A side blowing radiator and a wireless charger

technical field

The invention relates to a lateral blowing radiator and a wireless charger, which relate to the technical field of electronic products, in particular to a lateral blowing radiator and a wireless charger with heat dissipation function.

Background technique

With the popularization and application of wireless charging technology in mobile phones, smart watches, earphones, electric toothbrushes, computers, electric tools and other electrical appliances, it brings great convenience and interface compatibility to people's work and life.

Some of the existing wireless chargers on the market do not have a built-in heat dissipation mechanism, and the heat cannot be dissipated in time during the charging process, which will cause the temperature of the charging area to be too high, triggering a series of problems such as overheating protection, exiting the program, and restarting the phone after the phone crashes. damage the battery of the mobile phone and reduce the service life of the mobile phone; some are because they only have a fan blowing to do simple spoiler blowing, neither use semiconductor cooling chips, nor use side blowing blowing devices supplemented by directional heat dissipation teeth of heat sinks The heat dissipation effect is still not ideal, and it is not very helpful to consumers who like to play mobile games and use mobile phones for navigation when driving in summer.

technical problem

There are existing products on the market that combine special mobile phone radiators or wireless chargers with radiators. They all adopt the structural design of placing the heat dissipation components at the upper and lower positions consisting of electronic fans, heat sinks, and semiconductor cooling chips. This design The fan is nested in the heat sink to blow and dissipate heat. The journey of the cool air from the fan to the heat sink and then blown out of the heat dissipation cavity is very short, and the heat exchange is not sufficient; Because the air inlet and outlet are too close, the hot and cold air do not have separate channels in the heat sink, and they are still disturbed back and forth in the heat sink cavity, the cold and heat exchange is chaotic and the convection is insufficient, and the heat dissipation efficiency is poor. The product of this type of design has a large thickness and a small contact surface with the mobile phone, so it cannot provide stable support when used as a car charger; when used as a desktop wireless charger, it cannot be placed flat, because the air inlet of the electronic fan when placed flat It is directly blocked by the desktop. The worst user experience is that the fingers will blow the hot air blown by the fan for a long time during use, causing baking and discomfort to the fingers.
