Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a ship battery charger. Background Technology

[0002] With the increasing number of boats on the market, many companies have emerged to design and develop professional boat chargers based on market demand. The currently available JUMP MONSTER boat charger features a three-output design that can charge three batteries simultaneously. When only one battery is connected, the maximum charging current reaches 30Amp; when three batteries are connected, the average output current per battery is 10Amp. The charging process is divided into nine stages, which better protects and extends battery life. It can charge not only boats but also cars, motorcycles, and trucks. Besides personal use, it is also suitable for repair shops, as it can charge three batteries simultaneously with higher charging efficiency. Furthermore, it can repair sulfation in batteries, restoring their functionality.

[0003] However, when a single charging current of 30Amp is output or three charging currents of 10Amp are output simultaneously, the heat generated is relatively large, so improving its heat dissipation efficiency is particularly important. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A ship battery charger includes a charger housing 1, within which multiple PCB boards 2 are arranged side-by-side at intervals. Components for charging management are mounted on the PCB boards 2. The charger housing 1 has power connectors 3 corresponding to the multiple PCB boards, and multiple output connectors 4 corresponding one-to-one with each of the multiple PCB boards.

[0026] The components on PCB 2 include at least resistors and / or capacitors and / or transformers, which generate significant heat during charging management. When these components generate heat, some of the heat is transferred to PCB 2 through direct contact, while some is dissipated through other means. For example, by using gallium nitride (GaN), which has good thermal conductivity, to bond these heat-generating components to the charger housing 1, the heat from the components can be quickly conducted to the charger housing 1 via GaN; or the heat from the components can be quickly conducted to other locations, such as other parts of PCB 2, via GaN.

[0027] A gap 5 is formed between adjacent PCB boards 2. A sliding hole 9 corresponding to the gap 5 is passed through the outer side of the charger housing 1. A heat dissipation plate 13 is slidably mounted on the sliding hole 9. One side of the heat dissipation plate 13 passes through the sliding hole 9 and extends out of the charger housing 1.

[0028] An additional protection plate 12 is provided on the outside of the charger housing 1 and is connected to one side of the heat dissipation plate 13 that extends out of the charger housing. The additional protection plate 12 is connected in sequence to one side of multiple heat dissipation plates 13 that extends out of the charger housing, so that the additional protection plate 12 can form a linkage structure of multiple heat dissipation plates.

[0029] Please refer to the details. Figure 3 , 4 In this embodiment, the PCB board 2 has a front surface, a back surface, and a side surface, and the gap 5 between adjacent PCB boards is located between the side surfaces of adjacent PCB boards. That is, multiple PCB boards are arranged side by side with their side surfaces spaced apart, which makes the front surface and back surface of each PCB board 2 have good heat dissipation conditions, and effectively reduces the temperature influence of adjacent PCB boards.

[0030] In some embodiments, when the heat dissipation slide plate 13 slides on the sliding hole 9, its sliding direction is perpendicular to the front or back panel of the PCB board 2.

[0031] In some embodiments, the additional protection plate 12 is a protection plate made of a material with good heat dissipation efficiency, such as the additional protection plate 12 and the heat dissipation plate 13 both being made of aluminum.

[0032] When the heat dissipation slide plate 13 slides in the direction of entering the charger housing 1, the additional protection plate 12 moves in the direction of moving closer to the outside of the charger housing 1, so that the additional protection plate 12 can form enhanced protection for the charger housing 1.

[0033] When the heat dissipation slide plate 13 slides along the direction of extending out of the charger housing 1, the additional protection plate 12 moves in a direction away from the outside of the charger housing 1, so as to work together with the heat dissipation slide plate 13 to increase the heat dissipation area and improve the heat dissipation efficiency.

[0034] In some embodiments, when the heat dissipation slide plate 13 slides along the direction of exiting the charger housing 1 and slides into place, a portion of the heat dissipation slide plate 13 is located inside the charger housing 1, so that the heat inside the charger housing 1 can be better transferred to the heat dissipation slide plate 13.

[0035] In some embodiments, the charger housing 1 is provided with heat-conducting elements 6 corresponding to the sliding holes 9. The heat-conducting elements 6 conduct heat from the charger housing 1 to the corresponding heat dissipation plate 13. For example, a part of the heat-conducting element 6 is in contact with the PCB board 2, and a part of the heat-conducting element 6 is in contact with the heat dissipation plate 13.

[0036] In some embodiments, the gallium nitride used above can also be used to enable the heat of the components to be quickly conducted to the heat conductor 6 via gallium nitride.

[0037] In some embodiments, when the heat dissipation slide plate 13 is slid to adjust the heat dissipation position, the heat conduction element 6 can remain in contact with the heat dissipation slide plate 13. For example, the heat conduction element 6 has an elastic clamping part 7, which maintains clamping contact with the heat dissipation slide plate 13. Moreover, the clamping of the elastic clamping part 7 makes it difficult for the heat dissipation slide plate 13 to slide on its own after the user has adjusted the sliding position of the heat dissipation slide plate 13, effectively and stably maintaining its position.

[0038] In some embodiments, the heat-conducting element 6 has a groove 8 corresponding to the heat dissipation slide plate 13, and the heat-conducting element 6 covers the corresponding sliding hole 9 and makes the groove 8 and the sliding hole 9 communicate with each other.

[0039] The heat-conducting component 6 serves two purposes: firstly, it improves the efficiency of heat conduction and dissipation; secondly, it forms a sealing effect on the sliding hole 9, preventing water from entering and short-circuiting during the charging of the ship's battery.

[0040] In some embodiments, a recessed hand groove 10 corresponding to the additional protective plate 12 is formed on the outer side of the charger housing 1.

[0041] In some embodiments, a heat dissipation extension 11 with outward protrusion and / or inward concavity is formed on the outer side of the charger housing 1.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
