The charging device 1 includes a housing 100, a charging module 200, and a heat exchange module 300. The housing 100 is provided with a receiving cavity 110. The charging module 200 is received in the receiving cavity 110. The heat exchange module 300 comprises a finned heat exchanger 310, the finned heat exchanger 310 is connected with the charging module 200, the finned heat exchanger 310 is accommodated in the accommodating cavity 110, and part of the finned heat exchanger 310 is exposed to the housing 100.
For the above-mentioned finned heat exchanger 310, please refer to fig. 4 and 5, which respectively show a perspective view of the finned heat exchanger 310 provided in one embodiment of the present application and a cross-sectional view of a plane a of fig. 4 provided in one embodiment of the present application. The fin heat exchanger 310 includes a base plate 311 and fins 312, the fins 312 are mounted on the base plate 311, the base plate 311 is connected with the charging module 200, and the fins 312 are exposed to the housing 100. It should be noted that the heat exchange area formed by the part of the fins 312 exposed to the casing 100 and the base plate 311 can make the air sufficiently contact with the fins 312 to increase the heat exchange. In some embodiments, the finned heat exchanger 310 comprises at least two fins 312, as shown in FIG. 5, each fin 312 represented by a in FIG. 5 has a thickness a of at least 1 millimeter, a height b of each fin 312 of at least 5 millimeters, and a distance c between two adjacent fins 312 of at least 10 millimeters. The height b of the fin 312 is a distance between one end of the fin away from the base 311 and the base 311. It is understood that the area of the substrate 311 is generally slightly larger than the contact area of the connection portion of the substrate 311 and the charging module 200. Because a boundary of equal temperature is formed at the connection between the substrate 311 and the charging module 200. It is necessary to extend the area of the substrate 311 so that the temperature of the surface of the substrate 311 can be further reduced and then transferred to the external environment or the housing 100 connected to the substrate 311. Thereby increasing the useful life of the housing 100. In addition, a protrusion and/or a groove matched with the charging module 200 are/is further arranged on the surface of the connection between the substrate 311 and the charging module 200, so that the connection between the substrate 311 and the charging module 200 is tighter, and the heat exchange area is increased.
It should be noted that the three examples provided above are data obtained by comparative experiments.

TABLE 1
From a comparison of the experimental data in scheme one to scheme eight in table 1: when the ambient temperatures are equal, the lengths of the fins 312, the heights of the fins 312, the materials and other variables are equal, and only the thickness of the fins 312, the number of the fins 312 and the spacing between the fins 312 are used as comparison variables, the heat sink temperatures of the first, second and third schemes are closer to the ambient temperature of 55 degrees celsius than the heat sink temperatures of the fourth, fifth, sixth and seventh schemes. Therefore, under the same condition, the heat dissipation capacity of the scheme I, the scheme II and the scheme III is larger, and the heat transfer efficiency is higher.
In some embodiments, please refer to fig. 6, which illustrates a perspective view of a zigzag heat exchanger 320 provided in another embodiment of the present application. The heat exchange module 300 further includes a zigzag heat exchanger 320, i.e., gaps are added on the fins to form tooth-shaped fins 321, so that air can convect between the teeth of the tooth-shaped fins 321. Thereby achieving the purpose of accelerating the heat exchange speed. Alternatively, the tooth pitch of the zigzag type heat exchanger 320 is 3 to 5 mm.
Referring to fig. 3, an exploded view of the charging module 200 is shown in the present application. The charging module 200 includes a PCB board 210 and a thermally conductive layer 220. Wherein, a gap exists between the PCB 210 and the heat exchange module 300. Specifically, since errors of parts are difficult to avoid during the manufacturing and mounting processes of the parts, a gap is generally formed between the PCB 210 and the substrate 311 of the heat exchange module 300, and the thermal resistance of air existing in the gap is high, which may affect the heat dissipation efficiency if the contact area between the substrate 311 and the PCB 210 is reduced. And the heat conduction layer 220 is used for filling the gap so as to make the fit between the substrate 311 and the PCB 210 more tight. Alternatively, the heat conduction layer 220 between the PCB 210 and the substrate 311 may be a heat conduction pad, or a heat conduction glue may be coated on a side of the PCB 210 close to the substrate 311. Meanwhile, the heat conducting layer 220 can quickly diffuse the heat locally concentrated on the PCB 210 and transfer the heat to the substrate 311 and the fins 312, thereby reducing the occurrence of heat concentration.
In the present embodiment, the charging device 1 further includes an auxiliary power supply 500 and a relay 600. The auxiliary power supply 500 is used to supply power to the relay 600, and the relay 600 is used to control the charging device 1.
The charging device 1 provided by the embodiment of the present application includes a housing 100, a charging module 200, and a heat exchange module 300. The housing 100 is provided with a receiving cavity 110. The charging module 200 is received in the receiving cavity 110. The heat exchange module 300 comprises a finned heat exchanger 310, the finned heat exchanger 310 is connected with the charging module 200, the finned heat exchanger 310 is accommodated in the accommodating cavity 110, and part of the finned heat exchanger 310 is exposed to the housing 100. Through the structure, when the temperature inside the charging device 1 rises, the finned heat exchanger 310 can disperse and dissipate the heat of the charging device 1 concentrated at the charging module 200, so that the temperature of the working environment of the charging module 200 is reduced, the safety of the internal electronic elements of the charging device 1 is protected, and the working efficiency of the charging module 200 is improved.
Based on the same inventive concept, the present application further provides an electrical device (not shown), which includes the charging apparatus 1 described above.
