Examples
As shown in fig. 1 and 2, the present embodiment discloses a battery charger, which includes a housing 400, a heat sink 100, a charging motherboard 200, and a power tube 500. Wherein the heat sink 100 is mounted on the cabinet 400 with a mounting space between it and the bottom of the cabinet 400. The charging main board 200 is located in the installation space, is installed on the radiator 100 through an installation piece and forms a heat dissipation gap with the radiator 100, the installation piece comprises a plurality of copper columns and screws, the copper columns are installed on the radiator 100, and then the charging main board 200 is installed on the copper columns through the screws, so that the heat dissipation gap is formed between the charging main board 200 and the radiator 100. The power tube 500 is mounted on the heat sink 100 and located in the heat dissipation gap, and is electrically connected to the charging motherboard 200 through a wire. In this embodiment, the power tube 500 is directly installed on the radiator 100 and connected with the charging motherboard 200 through a wire, so that heat generated in the working process of the power tube 500 is better transferred to the radiator 100, and the heat dissipation effect of the power tube 500 is improved.
As another implementation of this embodiment, a thermally conductive silicone layer may be applied between the power tube 500 and the heat sink 100 when in a specific configuration.
In addition, the cabinet 400 includes a bottom plate 410, two side plates 430, and two end plates 450. The two side plates 430 are disposed on opposite sides of the bottom plate 410, respectively, and may be integrally formed with the bottom plate 410, as shown in fig. 4. Correspondingly, two end plates 450 are detachably mounted on the other two opposite sides of the bottom plate 410 by screws, specifically, as shown in fig. 6, a connecting plate 451 is arranged at the lower end of the end plate 450 and used for connecting with the bottom plate 410, the connecting plate 451 and the bottom plate 410 are connected together by screws during mounting, and clamping plates 452 capable of being buckled with the two side plates 430 are respectively arranged at the opposite ends of the end plate 450, and when the end plate 450 is mounted on the bottom plate 410, the two clamping plates 452 are respectively clung to the two side plates 430, so that the end plate 450 is more stable. Thus, the bottom plate 410, the two end plates 450 and the two side plates 430 together form the casing 400 with an open upper end.
The heat sink 100 is mounted on the side plate 430 and/or the end plate 450 with the mounting space therebetween with respect to the bottom plate 410 by screws, and the charging main plate 200 mounted on the heat sink 100 is directed toward the bottom plate 410. The heat sink 100 may also serve as an upper cover plate of the cabinet 400.
As shown in fig. 4 and 5, mounting flanges 420 are respectively disposed on two opposite sides of the bottom plate 410, and the mounting flanges 420 protrude downward from the bottom plate 410, so that when the chassis 400 is mounted on a mounting surface by the mounting flanges 420, a ventilation gap 460 is formed between the bottom plate 410 and the mounting surface, as shown in fig. 5. The ventilation gap 460 can ventilate and dissipate heat at the bottom of the casing 400, so as to improve the heat dissipation performance of the charger. The U-shaped mounting holes 440 can be formed in the mounting wing plate 420, and when the mounting wing plate 420 is mounted, the machine shell 400 is mounted on the mounting surface after screws pass through the U-shaped mounting holes 440, and the U-shaped mounting holes 440 are designed to facilitate fine adjustment of the position of the machine shell 400.

The heat generated in the operation process of the power tube 500 is transferred to the radiator 100, and when the external cold air flows through the heat dissipation channel 130, the external cold air exchanges heat with the radiator 100 to take away the temperature on the radiator 100, so that the power tube 500 can dissipate heat.
As another presentation manner of the present embodiment, as shown in fig. 8, the heat sink 110 may be wavy, so that the heat dissipation channel 130 forms a serpentine channel. In addition, blocking posts 140 are disposed in the heat dissipation channel 130 at intervals, and the diameter of the blocking posts 140 is smaller than the width of the heat dissipation channel 130, and the height of the blocking posts is the same as the height of the heat dissipation channel 130.
