Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a high heat dissipation charger. Background Art

[0002] Electronic devices such as mobile phones and tablet computers need to be charged with chargers. Existing chargers include a housing, a plug and an output interface are arranged on the housing, and a circuit board is arranged inside the housing; a charger is a device that enables an electronic device to work continuously.

[0003] For example, the charger disclosed in CN214626409U mainly has at least three independent circuit boards arranged in its housing. Each circuit module is respectively arranged on an independent circuit board, and each independent circuit board is located on different planes in space, so that the circuit boards and their circuit modules are stacked in a three-dimensional space. The charger has a compact structure, reduced volume, and is convenient to carry and use; however, when the heat inside the charger is too high, it will cause damage to the internal parts of the charger, and then there are potential safety hazards in the device; and when the internal parts of the charger need to be maintained, it will increase the time required for maintenance and reduce the working efficiency of the device. To solve the above problems, the patent number: 202222582789.9, which discloses a charger with high heat dissipation, including a charger body. A conductive sheet is symmetrically fixed and installed at the top of the back of the charger body. A flame retardant coating is coated on the outer surface of the charger body. A connection port is opened in the middle of the front of the charger body. A connector is clamped through the connection port in the middle of the front of the charger body. A charging cable is fixedly installed in the middle of the front of the connector, and a charging head is fixedly installed at one end of the charging cable. In the above solution, the charger is provided with heat dissipation holes and heat sinks. When the circuit components inside the charger body dissipate heat, the heat sinks will work at this time. Then, the heat sinks cool the inside of the charger body through the conduction method of heat. Coupled with the heat dissipation holes, the heat generated inside the charger body will be dissipated, which is more conducive to the heat dissipation work of the charger body, ensuring the quality of the device and making the device free of potential safety hazards. However, this charger still has the following problems: 1. The heat dissipation method using heat dissipation holes is likely to affect the sealing performance, making the use of the charger have certain limitations, and the heat dissipation holes may be blocked after long-term use, affecting the heat dissipation effect and easily causing short circuits inside, affecting the use safety; 2. The intuitive promptness is poor. The charger generates heat during use, and people cannot intuitively know its use temperature. When the charger is used for a long time or abnormally, it will generate a large amount of heat. The user cannot immediately and intuitively know the temperature of the charger, which is likely to cause potential safety hazards in use, and the safety promptness is poor.
