In addition, there is an increasing demand for a charging device having a large charging current and a high charging speed. The heat generated during charging of the battery is increased by the charging device with large charging current and fast charging. The charging device is internally provided with a charging circuit such as AC-DC or DC-DC, so that the charging device itself generates heat, and the heat is transferred to the outer surface of the charging case by means of heat transfer, resulting in an increase in the temperature of the charging case.

As shown in fig. 1, 2 and 3, a charging device is provided, which includes a charging housing 1, wherein a battery mounting position for mounting a battery 2 is provided on the charging housing 1; the outer surface of the charging case 1 can have a gap 3 with the main heat radiating surface of the battery 2 mounted on the battery mounting site.
The embodiment of the utility model provides a charging device, battery 2 install back on the battery installation position, have clearance 3 between the surface of charging case 1 and the main cooling surface of battery 2. Due to the presence of the gap 3, air enters the gap 3, blocking the outer surface of the charging case 1 from the main heat radiating surface of the battery 2. As air is a poor conductor of heat, heat transfer between the outer surface of the charging case 1 and the main heat dissipating surface of the battery 2 is effectively avoided; in addition, the air flows in the gap 3, and heat exchange is also generated between the air and the outer surface of the charging case 1 and the main heat dissipation surface of the battery 2, so that the heat dissipation effect of the charging case 1 and the battery 2 is effectively improved. Through the heat dissipation, the temperature of the battery and the charging circuit inside the charging device is effectively reduced, the service life of the battery and the charging circuit inside the charging device is ensured, and the potential safety hazard in the charging process is reduced.
The thermal conductivity of air is about 0.02W/m · K, and the thermal conductivity of the charging case 1 is about ten times that of air even if plastic which is not easily thermally conductive is used.
It is understood that the charging circuit is installed in the charging housing 1. The outer surface with larger area on the battery is the main heat dissipation surface. Whereas in the prior art, the primary heat dissipating surface of the battery is in direct contact with the outer surface of the charging housing. Taking a conventional cuboid as an example, two surfaces which are large in area and symmetrically arranged exist on the cuboid, and the two surfaces are main heat dissipation surfaces.
In order to facilitate mounting of the battery 2 to a battery mounting location on the charging housing 1 of the charging device, the battery mounting location is located on the top surface of the upper shell of the charging housing 1. The battery mounting position may also be provided on the side of the charging case 1.
As shown in fig. 1 and 2, the battery mounting site includes a conductive connecting surface 14, a positioning surface 13 and a clearance surface 12. The electrically conductive connection surface 14 is used for electrically conductive connection with the battery 2; the positioning surface 13 and the conductive connecting surface 14 are symmetrically arranged and used for extruding the battery 2 to the conductive connecting surface 14; the clearance face 12 faces the outside of the charging device. Wherein the clearance face 12 is capable of forming a clearance 3 with a primary heat dissipating face of the battery 2 mounted on the battery mounting site. Through the arrangement, the installation stability of the battery 2 on the charging device can be ensured, and the condition that the combined structure of the battery 2 installed on the charging device occupies too large space is also avoided.
As shown in fig. 1, the clearance face 12 is an inclined face provided obliquely to the battery 2 for mounting at the battery mounting site; the high end of the inclined surface is connected with one of the conductive connecting surface 14 and the positioning surface 13, and the low end of the inclined surface is connected with the other of the conductive connecting surface 14 and the positioning surface 13. In this embodiment, the high end of the inclined surface is connected to the conductive connection surface 14, and the low end of the inclined surface is connected to the positioning surface 13. After the battery 2 is installed in the battery installation site, the gap 3 formed between the main heat dissipation surface of the battery 2 and the clearance surface 12 increases in the direction from the electrically conductive connection surface 14 to the positioning surface 13. To facilitate the installation of the battery 2, the battery 2 is connected to the positioning surface 13 on the side where the gap 3 is larger. Of course, the battery 2 may be connected to the conductive connection surface 14 on the side where the gap 3 is larger.
The upper end of the inclined surface is a contact end for contacting the end of the battery 2. During the mounting process, one end of the battery 2 is in contact with the high end of the inclined surface. In order to further improve the stability, the lower end of the inclined surface is provided with a convex structure 11 for positioning and supporting with the end part of the battery 2; alternatively, the other surface is a stopper surface capable of restricting the movement of the battery 2 toward the clearance surface 12. With the above arrangement, the mounting stability of the battery 2 on the charging device is effectively improved while ensuring the formation of the gap 3.
As shown in fig. 2, the conductive connection surface 14 and the positioning surface 13 are both limiting surfaces capable of limiting the movement of the battery 2 to the clearance surface 12. With the above arrangement, the battery 2 can be mounted between the conductive connection surface 14 and the positioning surface 13.
In this embodiment, the conductive connection surface 14 and the positioning surface 13 are both inclined end surfaces that are close to each other in the direction close to the gap surface 12. Through the arrangement, the battery 2 can be erected on the conductive connecting surface 14 and the positioning surface 13, the contact between the main radiating surface of the battery 2 and the clearance surface 12 is avoided, and the formation of the clearance 3 is ensured.
The positioning surface 13 is parallel to the inner side surface of the battery in consideration of the heat dissipation uniformity; the inner side of the battery is the main heat dissipation surface facing the positioning surface 13 for the battery 2 mounted on the battery mounting site.
As shown in fig. 3, the battery mounting position is a fixing portion capable of fixing the power supply connection terminal of the battery 2. Through the arrangement, one end of the battery 2, which is far away from the power connection end of the battery, can be suspended, so that a relatively stable gap 3 can be formed between the outer surface of the charging shell 1 and the main radiating surface of the battery 2 installed on the battery installation position. In order to avoid that the overall volume of the charging device on which the battery 2 is mounted occupies too much space, the battery 2 is typically arranged obliquely. Of course, it is also possible to arrange the battery 2 vertically with respect to the charging device. Wherein the mounting position of the battery 2 with respect to the charging device depends on the structural limitations of the battery mounting position.
In this embodiment, the fixing portion is an insertion groove capable of inserting a power connection end of the battery; alternatively, the fixing portion is a holding portion capable of holding the power connection terminal of the battery. Of course, the fixing portion may have another structure, and it is only necessary to secure that the fixing portion can fix the power connection terminal of the battery 2.
In addition, a connection terminal capable of electrically connecting to the power supply connection terminal of the battery 2 needs to be provided in the fixing portion.
