Description

Heat radiation structure of battery charger

Technical Field

Background

The charger is a device for converting alternating current into low-voltage direct current and is used for charging a battery. The portable electronic device is widely used in various fields, particularly in the living field, and is widely used for common equipment such as mobile phones, cameras, toy vehicles and the like. The types of battery chargers have been developed in many types, including smart chargers, nickel metal hydride battery chargers, lithium ion battery protection circuit chargers, lithium ion battery chargers for portable electronic devices, and the like.

With the rapid development of modern society, more places are used with battery chargers, which brings great convenience to life of people, in particular to people who need to go out.

When the charger charges the battery, a large amount of heat is generated, if the heat of the charger is not timely dissipated, the shell of the charger and the power line are easy to burn, and the performance of internal elements of the charger is reduced or even damaged due to the high-heat working environment in the past for a long time, so that the service life of the charger is reduced, and the sustainable use of consumers is not facilitated; therefore, the charger needs to have a heat dissipation structure.

At present, the heat radiation structure of battery charger has some shortages, for example, the charger body just sets up some louvres or radiating fins in the charger body outside and dispels the heat in the charging process to can not dispel the heat fast to the charger body bottom, make the charger body can generate heat and send out scalding, unable cooling, moreover, the top of charger body also does not possess dustproof construction, and the inside heat dissipation cooling that falls into the dust of charging groove can influence the charger body. Therefore, we need a heat radiation structure of battery charger, which can radiate heat and cool down the bottom of the charger body, avoid the heat generation and scalding of the charger body, and protect the outside of the charging slot from dust.

For example, the prior patent publication CN217063360U provides a battery charger reinforcing heat dissipation structure, which achieves the effects of slowing down the aging of a charger circuit and prolonging the service life of the charger, solves the problems that the prior battery charger structure is not in direct contact with an inner core or has small contact area, even if an aluminum shielding case is adopted, only the upper surface and the lower surface are in direct contact with a shell, and the two sides are not in contact with the shell, and the heat cannot be effectively and rapidly conducted to the shell due to slow air conduction heat, so that the temperature of the charger is always kept at a higher temperature, the aging of the charger circuit is easy to accelerate, and potential safety hazards exist.

However, the structure is only suitable for grabbing solid food, and can not cool and cool the bottom end of the charger body, so that the charger body is prevented from heating and scalding, and the outer side of the charging groove is protected from dust.

The heat radiation structure of current battery charger, the charger body only sets up some louvres or radiating fin in the charger body outside and dispels the heat in the charging process to can not dispel the heat fast to the charger body bottom, make the charger body can generate heat and send out scalding, unable cooling, moreover, the top of charger body does not also possess dustproof construction, and the inside dust that falls into of charging groove can influence the heat dissipation cooling of charger body.
