Description

Technical Field

[0002] In the field of charging box heat dissipation devices, the development of heat dissipation technology is crucial to ensure effective charging of battery packs and extend their service life. As electronic devices develop towards high power density and high integration, heat dissipation issues become more prominent, especially in closed spaces such as charging boxes. Effective heat dissipation solutions are of great significance for maintaining stable operation of battery packs and extending their service life.

[0003] Traditional charging box heat dissipation technology solutions mainly rely on natural convection and fan-assisted heat dissipation. These methods reduce the internal temperature of the charging box by designing a certain heat dissipation space and the airflow generated by the fan. When the fan is running, it is easy to suck dust and other impurities into the charging box. These impurities will have an adverse effect on the electronic components of the charging power supply. At the same time, the thermal conductive structure design in the traditional heat dissipation solution is relatively complex, resulting in large thermal resistance and low thermal conductivity efficiency, which reduces the service life of the charging system.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. In addition, in the description with reference to the drawings, the same marks in different drawings represent the same elements.

[0033] The present disclosure provides a charging box heat dissipation device, such as Figure 1-5As shown, it includes a charging box housing 1 for accommodating a charging power source 6, and an internal heat dissipation module 12 installed inside the charging box housing 1. The internal heat dissipation module 12 includes: a heat dissipation fan 2 connected to the charging power source 6 through a mounting member; a heat-conducting column mounting groove 4, which is arranged on the inner surface of the charging box housing 1; and at least one heat-conducting column 5, which is installed in the heat-conducting column mounting groove 4 and contacts the charging power source 6.

[0034] In one embodiment of the present disclosure, Figure 4 As shown, the cooling fan 2 is connected to the charging power source 6 via screws.

[0035] In the present invention, the heat dissipation efficiency of the charging box is effectively improved by using a fan to directly dissipate heat from the charging power source, a fan to convectively dissipate heat from a heat-conducting column, the heat-conducting column conducts the heat of the charging power source to the outer shell for heat dissipation, and a fan to accelerate the heat dissipation of the shell. The design of the heat-conducting column shortens the heat conduction path and reduces the thermal resistance.

[0036] In one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, each of the at least one heat-conducting column 5 includes a first heat-conducting part 5.1 and two second heat-conducting parts 5.2, the two second heat-conducting parts 5.2 are respectively arranged at both ends of the first heat-conducting part 5.1, and the at least one heat-conducting column 5 is installed in the heat-conducting column installation groove 4 through the first heat-conducting part 5.1, and the two second heat-conducting parts 5.2 are in contact with the charging power supply 6.

[0037] In one embodiment of the present disclosure, Figure 1 , Figure 3 and Figure 4 As shown, at least one heat-conducting column 5 is installed on the upper surface and the lower surface of the charging power supply 6, the second heat-conducting part 5.2 is in direct contact with the charging power supply 6, and the length of the second heat-conducting part 5.2 is set according to the distance between the charging power supply 6 and the inner wall of the charging box shell 1, and the cooling fan 2 creates an airflow to directly blow the charging power supply 6 to dissipate heat. At the same time, the airflow flows through the charging power supply 6, the heat-conducting column 5 and the charging box shell 1, accelerating the heat dissipation of the charging power supply 6, the heat-conducting column 5 and the charging box shell 1.

[0038] In one embodiment of the present disclosure, Figure 1 and Figure 3 As shown, the length of the first heat-conducting part 5.1 is greater than that of the second heat-conducting part 5.2. The second heat-conducting part 5.2 conducts the heat generated by the charging power source 6 to the first heat-conducting part 5.1, and the first heat-conducting part 5.1 conducts the heat to the charging box shell 1. The one-dimensional dimension of the heat conduction direction of this structure is shorter than that of the traditional technology, and the thermal resistance is smaller than that of the traditional technology. At the same time, the circulating airflow in the charging box passes through the second heat-conducting part 5.2, the first heat-conducting part 5.1 and the charging box shell 1, further improving the heat dissipation efficiency.

[0039] The thermally conductive column 5 is made of a thermally conductive material, which is one or more of copper, aluminum, silver and their alloys. The at least one thermally conductive column 5 is a column or tube made of a thermally conductive material. The thermal conductivity of the thermally conductive material is large, which can ensure the rapid conduction of heat on the thermally conductive column 5.

[0040] In one embodiment of the present disclosure, Figure 1 and Figure 5 As shown, a heat-conducting layer 11 is disposed inside the heat-conducting column installation groove 4 , and the at least one heat-conducting column 5 is in contact with the heat-conducting layer 11 .

[0041] The heat-conducting layer 11 is one or more of thermal grease, thermal silica gel, heat dissipation paste, thermal double-sided tape, thermal adhesive and thermal film.

[0042] The thermally conductive column mounting groove 4 provides an installation position for the thermally conductive column 5 on the side panel of the charging box shell 1, which reduces the difficulty of assembly and reserves heat dissipation space between multiple thermally conductive columns 5. The thermally conductive layer 11 is arranged in the thermally conductive column mounting groove 4 and fits with the inner wall of the charging box shell 1. The heat of the charging power source 6 is conducted to the side wall of the charging box shell 1 and dissipated to the outside of the charging box through the thermally conductive column 5 and the thermally conductive layer 11. The thermally conductive layer 11 effectively reduces the contact thermal resistance between the thermally conductive column 5 and the side panel of the charging box shell 1, and increases the thermal conductivity efficiency between the thermally conductive column 5 and the charging box shell 1.

[0043] In one embodiment of the present disclosure, Figure 1 , Figure 2 and Figure 5 As shown, two dustproof devices 3 are provided on the outer surface of the charging box housing 1, and ventilation ports 13 are respectively provided on the two side walls of the charging box housing 1 corresponding to the air inlet and air outlet directions of the cooling fan 2, and the two dustproof devices 3 are respectively installed on the ventilation ports 13. The dustproof device 3 can filter impurities such as dust and reduce the impact of impurities on the electronic equipment in the charging box housing 1. Through the above structure, the service life of the charging system is increased.

[0044] In one embodiment of the present disclosure, Figure 2 and Figure 5 As shown, the ventilation port 13 is composed of hole-like openings spaced apart on the side wall of the charging box housing 1. The spaced apart distribution of the hole-like openings helps to optimize air flow and enhance heat dissipation performance, so that the air forms a good convection path inside the charging box, thereby discharging the high-temperature gas in the charging box more quickly and introducing the external low-temperature gas at the same time.

[0045] In other embodiments of the present disclosure, the ventilation port 13 may be formed of an opening structure in an elliptical shape, a strip shape, a grid shape, or any other shape.

[0046] In one embodiment of the present disclosure, Figure 2As shown, the dustproof device 3 includes a support 7, a dustproof filter 8 and a dustproof end cover 9. The support 7 is arranged on the side of the ventilation port 13, the dustproof filter 8 is installed on the support 7, and the dustproof end cover 9 covers the surface of the dustproof filter 8.

[0047] In one embodiment of the present disclosure, Figure 2 As shown, the support 7, the dust filter 8 and the dust end cover 9 are all connected and fixed by screws, and the support 7, the dust filter 8 and the dust end cover 9 have matching specifications and shapes.

[0048] In one embodiment of the present disclosure, Figure 2 As shown, the frame shapes of the support 7 , the dust filter 8 and the dust cover 9 are set to be rectangles of the same specifications, corresponding to the shape of the air outlet 13 .

[0049] The support 7 provides installation support for the dust filter 8, and the dust filter 8 can be removed for cleaning and replacement, reducing the update cost of the dust removal components of the charging box. The dust filter 8 filters dust and other impurities in the airflow, and excludes the impurities from the outside of the charging box housing 1 to prevent impurities from entering the charging power supply 6 and damaging the electronic components of the power supply. The dust end cover 9 presses the dust filter 8 and the support 7 to prevent the dust filter 8 from changing its position during the airflow flow, thereby ensuring that the gas flowing through the ventilation port 13 is filtered by the dustproof device 3.

[0050] In one embodiment of the present disclosure, Figure 2 As shown, a charging box upper end cover 10 is provided on the top surface of the charging box shell 1, and the charging box upper end cover 10 is fixed to the charging box shell 1 by bolts.

[0051] The upper end cover 10 of the charging box cooperates with the charging box shell 1 to form a closed charging box structure, which reduces the impact of external interference such as rain, sun, dust, etc. on the charging power supply 6 and increases the stability and service life of the charging system.

[0052] In one embodiment of the present disclosure, Figure 1-Figure 5 As shown, the working principle and process are as follows: when the charging power source 6 starts to charge, the temperature inside the charging box shell 1 will gradually increase. As the temperature of the charging box shell 1 increases, a temperature difference will be formed between the internal temperature and the external environment. The charging box shell 1 and the charging power source 6 are connected by the heat conducting column 5. Since the thermal resistance of the heat conducting column 5 is small and the one-dimensional scale of the heat conduction direction is shorter, the heat is efficiently dissipated from the charging power source 6 to the environment. When the temperature continues to rise, the heat conduction is not enough to dissipate the heat, and the cooling fan 2 starts to run and dissipates the heat by forced convection. At this time, due to the action of the dustproof device 3, impurities such as dust in the external circulating gas will be blocked on the dustproof filter 3. When too much dust accumulates and affects the incoming air flow, the dustproof filter 8 can be replaced to ensure smooth gas flow at the ventilation port 13.

[0053] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Although the present disclosure is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
