Description

Technical Field

[0001] This utility model relates to the field of charger structure, and in particular to a charger heat dissipation structure that utilizes a faceplate for auxiliary heat dissipation. Background Technology

[0002] With the rapid development of electric vehicle charging technology, the power density of internal power modules (such as gallium nitride switches and rectifier bridges) in chargers is constantly increasing, but the heat generated during operation is also increasing. If the heat cannot be dissipated effectively and in a timely manner, it will lead to performance degradation of electronic components, reduced charging efficiency, and even equipment failure or safety hazards. Traditional chargers mostly rely on natural heat dissipation or simple heat sink designs, such as placing metal heat sinks in local areas such as rectifier bridges and power transistors. However, their heat dissipation area is limited, and they do not form an effective heat conduction path with the charger casing, thus limiting heat dissipation efficiency. In addition, given the limited space of existing chargers, a simpler and more effective heat dissipation solution is needed. Utility Model Content

[0003] To address this problem, this utility model proposes a charger heat dissipation structure, including a front shell, a bottom shell, and a charging control management module, as well as a heat sink and an insulating layer. The charging control management module is disposed between the front shell and the bottom shell, and the charging control management module also includes a heat dissipation module. The heat sink is disposed in the heat dissipation area on the inner surface of the front shell, and the insulating layer covers the heat sink. When the front shell is placed on the charging control management module, the insulating layer contacts the heat dissipation module on the charging control management module.

[0004] Furthermore, an adhesive layer is included between the heat sink and the heat dissipation area inside the casing.

[0005] Furthermore, the adhesive layer is a thermally conductive adhesive.

[0006] Furthermore, the insulation layer covers a larger area than the heat sink.

[0007] Furthermore, the insulation layer is an insulating sticker, which is attached to the heat sink.

[0008] Furthermore, the heat dissipation area on the inner surface of the casing covers the heat dissipation module.

[0009] Furthermore, the charging control management module includes a circuit board, the heat dissipation module, an output / input interface, a control chip, and a protection circuit.

[0010] Compared with existing technologies, the advantages of this utility model are:

[0011] The heat generated by the charging control and management module is dissipated through the casing by the heat sink, which improves the heat dissipation efficiency of the charger, prevents the electronic components inside the charger from aging faster due to high temperature, and thus extends the life of the charger.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please refer to Figures 1-3 The proposed charger heat dissipation structure includes a front shell 1, a bottom shell 2, and a charging control management module 3. The charging control management module 3 is disposed between the front shell 1 and the bottom shell 2. The charging control management module 3 includes a circuit board 31 and various electronic components and a heat dissipation module 32 on the circuit board. It is mainly used to manage the charging process of the charger for the electric vehicle during use and various functional modules. In addition to the circuit board 31 and the heat dissipation module 32, it also includes an output / input interface, a control chip, and a protection circuit.

[0028] Between the charging control management module 3 and the housing 1, there is also a heat sink 4 and an insulating layer 5; a heat dissipation area 11 is provided inside the housing 1, and the entire heat dissipation area 11 covers the heat dissipation module 32 of the charging control management module 3. The heat sink 4 is provided in the heat dissipation area 11 on the inner surface of the housing 1, and the insulating layer 5 covers the heat sink 4. Furthermore, an adhesive layer (not shown in the figure) can be provided between the heat sink 4 and the heat dissipation area 11 of the housing 1, that is, the heat sink 4 and the heat dissipation area 11 are combined by adhesive. The adhesive layer can be a thermally conductive adhesive, such as thermally conductive silicone. The heat sink 4 can be made of brass or other metal materials with high thermal conductivity. In this embodiment, the insulating layer 5 can be an insulating sticker with adhesive backing, which is attached to the heat sink 4 by adhesive. In order to better avoid the risk of short circuit caused by direct contact between the charging control management module 3 and the metal heat sink 4, the area covered by the insulating layer 5 should be larger than the area of ​​the heat sink 4. It is better to completely cover the entire coverable area of ​​the inner surface of the shell 1. This can prevent the heat sink 4 from falling off and also better avoid the risk of contact between the heat sink 4 and the charging control management module 3.

[0029] When the cover 1 is placed on the charging control and management module 3, the insulating layer 5 contacts the heat dissipation module 32 on the charging control and management module 3. During the operation of the charger, the heat dissipation module 32 can conduct heat to the insulating layer 5 through contact, and then transfer heat from the insulating layer 5 to the heat sink 4, and then dissipate heat through the cover 1. This achieves a better heat dissipation effect, avoids the risk of electronic components aging or spontaneous combustion due to high temperature, and also improves the service life of the charger.
