Description
Technical Field
[0001] The utility model relates to the field of mobile charging devices, and in particular to a mobile charger. Background Art
[0002] With the development of new energy vehicles, people have more and more demands and requirements for charging piles, and a variety of mobile chargers have gradually been introduced on the market to facilitate the on-vehicle charging of new energy vehicles when traveling long distances.
[0003] At present, the mainstream mobile chargers all adopt charging modules with high-efficiency DC fast charging, combined with advanced intelligent dynamic charging adjustment technology, to achieve a charging effect with high conversion rate and high stability, and have the characteristics of high charging efficiency, simple operation, light weight, and small volume. However, since the charging module generates heat during operation and causes the temperature inside the charger to rise, if the temperature of the charging module is too high, it will directly affect the conversion efficiency of the charging module and even burn out other circuit components inside the charger. Therefore, general mobile chargers are usually equipped with corresponding heat dissipation devices to maintain the charging efficiency of the charging module and protect other circuit components.
[0004] Most of the heat dissipation methods of mobile chargers are to set up cooling fans to dissipate heat inside the charger. However, due to the lack of a reasonable air duct design, the cooling fans cannot fully dissipate heat from the charging module, and the overall heat dissipation effect is not ideal. Summary of the Utility Model
[0005] In order to improve the heat dissipation method of the charger and enhance the heat dissipation efficiency of the charger, this application provides a mobile charger.
[0006] The mobile charger provided by this application adopts the following technical solutions:
[0007] A mobile charger includes a chassis, a charging mechanism, and a heat dissipation mechanism;
[0008] The charging mechanism includes a charging module and a control element group for controlling the charging module. A support frame is arranged inside the chassis, and a main air duct is formed between the support frame and the bottom side of the chassis. The support frame mounts the charging module directly above the main air duct;
[0009] A top air duct is formed between the charging module and the top side of the chassis, and side air ducts are formed between the charging module and the two sides of the chassis. The main air duct, the top air duct, and the side air ducts are interconnected. Side plates are detachably arranged on the two sides of the chassis, and a number of evenly arranged side air inlets are opened on the side plates. The side air inlets connect the side air ducts with the outside of the chassis;
[0010] The heat dissipation mechanism includes a main heat dissipation fan and a module heat dissipation fan. The main heat dissipation fan is arranged on both sides of the chassis and is located on both sides of the main air duct. The main heat dissipation fan communicates the main air duct with the outside of the chassis. The module heat dissipation fan is arranged on the top of the charging module, and the module heat dissipation fan communicates the top of the charging module with the top air duct.
[0011] By adopting the above technical solution, when the charging module generates heat, the heat generated at the top of the charging module can be dissipated into the top air duct through the module heat dissipation fan, while the heat on both sides of the charging mechanism is directly dissipated into the side air duct, and the heat generated at the bottom of the charging mechanism is directly dissipated into the main air duct. When the main heat dissipation fan is started, the main heat dissipation fan continuously dissipates the heat in the main air duct to the outside of the chassis. At this time, due to the continuous air extraction and heat dissipation of the main heat dissipation fan, the air pressure in the main air duct decreases. Therefore, the hot air in the side air duct and the top air duct will flow into the main air duct along the heat dissipation air duct due to the air pressure. The heat generated at the top and both sides of the charging module converges in the main air duct along with the air flow, and finally is fully dissipated to the outside of the chassis through the main heat dissipation fan. In addition, the cold air in the environment outside the chassis can also enter the interior of the chassis from the side air inlet. The newly entered cold air not only directly cools the charging module, but also makes up for the air inside the chassis, making the air flow inside the chassis stable, which is beneficial to improving the heat dissipation efficiency inside the chassis and fully cooling the charging module.
[0012] Optionally, a bottom plate is detachably arranged on the bottom side of the chassis, and a plurality of bottom air inlets are opened on the bottom plate at evenly arranged intervals. The bottom air inlets communicate the main air duct with the outside of the chassis.
[0013] By adopting the above technical solution, the bottom air inlets can cooperate with the side air inlets to further increase the air intake of the chassis. When the heat dissipation mechanism starts to work, the cold air outside the chassis can not only enter the interior of the chassis from the side air inlet, but also enter from the bottom air inlet, so as to fully exchange heat at the bottom of the charging module and fully cool and dissipate heat at the bottom of the charging module. Moreover, the detachable design of the bottom plate enables the user to regularly remove the bottom plate and clean the dust in the main air duct, which is beneficial to reducing the dust accumulation in the heat dissipation air duct and improving the heat dissipation efficiency.
[0014] Optionally, a bottom dust-proof net is arranged on the side of the bottom plate facing the interior of the chassis, and the bottom dust-proof net covers the bottom air inlets.
[0015] By adopting the above technical solution, the bottom dust-proof net can block most of the dust and impurities from entering the main air duct while maintaining gas flow, keeping the interior of the chassis clean. This is not only beneficial to preventing the direct impact of dust and impurities on the charging mechanism, but also beneficial to reducing the heat accumulation caused by excessive dust inside the chassis, which is beneficial to ensuring the heat dissipation efficiency.
[0016] Optionally, a plurality of groups of arc-shaped guard eaves are arranged on the outer side of the side panel, and the arc-shaped guard eaves correspond one-to-one to the side air inlets.
[0017] By adopting the above technical solution, the arc-shaped eaves can block the side air inlet from above the side air inlet, thereby effectively blocking rain or dust from falling into the chassis from the side air inlet, which is beneficial to prevent rain, dust and other impurities from directly affecting the charging mechanism.
[0018] Optionally, a side dust screen is provided on the side of the side panel facing the inside of the chassis, and the side dust screen cover is provided on the side air inlet.
[0019] By adopting the above technical solution, the side dust screen can block most of the dust and impurities from entering the side air duct while maintaining gas circulation, thereby keeping the interior of the chassis clean and tidy. This is beneficial for preventing dust and impurities from directly affecting the charging mechanism, and is also beneficial for reducing the accumulated heat caused by excessive dust inside the chassis, thereby ensuring heat dissipation efficiency.
[0020] Optionally, a fixed partition is further provided inside the chassis, the charging module is located on one side of the fixed partition, and the control element group is provided on a side of the fixed partition away from the charging module.
[0021] By adopting the above technical solution, the fixed partition separates the charging module and the control element group, thereby effectively blocking the heat generated by the charging module from being transferred to the control element group, reducing the impact of the heat generated by the charging module on the control element group, which is beneficial to protecting the control element group and improving the service life of the charging mechanism.
[0022] Optionally, a grille baffle is provided on the top of the charging module, and the module cooling fan is arranged between the grille baffle and the charging module.
[0023] By adopting the above technical solution, since the blades of the module cooling fan are oriented in the vertical direction, the grille baffle can effectively block some larger sand and gravel or other impurities from falling on the module cooling fan, which is not only beneficial to prevent sand and gravel and other impurities from affecting the normal operation of the module cooling fan or the charging module, but also beneficial to protecting the module cooling fan and extending the service life of the module cooling fan.
[0024] Optionally, four sets of universal wheels are arranged on the outer side of the bottom of the chassis, and a telescopic pull rod is arranged along the outer wall of the back side of the chassis.
[0025] By adopting the above technical solution, the user can easily and conveniently move the charger by pulling the telescopic rod and then cooperating with the universal wheels, which is conducive to improving the portability and mobility of the mobile charger.
[0026] In summary, the technical solution of this application has at least one of the following beneficial effects:
[0027] 1. By reasonably setting the fixing method of the charging module inside the chassis, a coherent main air duct, top air duct and side air duct are formed between the charging module and the chassis. The heat dissipation mechanism only needs to dissipate heat from the main air duct, and the overall heat generated by the charging module in all directions can be fully dissipated to the outside of the chassis along with the air flow in the heat dissipation air duct, which is beneficial to improving the heat dissipation efficiency of the chassis.
[0028] 2. By setting a fixed partition to separate the charging module from the control component group, the influence of the heat generated by the charging module on the control component group can be effectively reduced, which is beneficial to protecting the control component group and improving the service life of the charging mechanism.

[0037] The following will Figures 1-6 further elaborate on the present application in detail with reference to the attached
[0038] The embodiment of the present application discloses a mobile charger. Refer to Figure 1, Figure 2 and Figure 3 , a mobile charger includes a chassis 1, a charging mechanism 2, and a heat dissipation mechanism 3. Among them, the charging mechanism 2 is arranged inside the chassis 1 and is used as the main charging device in the charger. The heat dissipation mechanism 3 is used to dissipate heat from the charging mechanism 2 and the inside of the chassis 1 to reduce the temperature inside the chassis 1 and prevent the charging mechanism 2 from overheating. Specifically, the charging mechanism 2 is reasonably arranged inside the chassis 1. The inner side walls of the chassis 1 cooperate with each other to form a heat dissipation air duct 4 inside the chassis 1. The hot air in the chassis 1 is concentrated and guided through the heat dissipation air duct 4, and then combined with the heat dissipation mechanism 3, greatly improving the heat dissipation efficiency inside the chassis 1, thereby realizing sufficient heat dissipation and temperature reduction of the charging mechanism 2.
[0039] Referring to Figure 2 , Figure 3 and Figure 4 , the charging mechanism 2 includes a charging module 21 and a control component group 22. The charging module 21 is electrically connected to the control component group 22. Among them, the charging module 21 is used to store, convert, and release electrical energy, and the control component group 22 is used to control the charging module 21. A support frame 11 and a fixed partition 12 are arranged inside the chassis 1. Specifically, the support frame 11 is arranged at the bottom side of the chassis 1, and a main air duct 41 is formed between the support frame 11 and the bottom side of the chassis 1. The fixed partition 12 extends vertically, and the fixed partition 12 divides the inside of the chassis 1 into two cavities. The charging module 21 is located in one cavity of the chassis 1 separated by the fixed partition 12 and is detachably installed on the support frame 11. The support frame 11 mounts the charging module 21 directly above the main air duct 41, so that the heat generated at the bottom end of the charging module 21 can be dissipated through the main air duct 41. The control component group 22 is located in the other cavity of the chassis 1 separated by the fixed partition 12 and is arranged on the side of the fixed partition 12 facing away from the charging module 21. Thus, the fixed partition 12 separates the charging module 21 and the control component group 22. When the charging module 21 works, it can greatly reduce the influence of the heat generated by the charging module 21 on the control component group 22, which is beneficial to protecting the control component group 22 and improving the service life of the charging mechanism 2.
[0040] Referring to Figure 3 , a top air duct 42 is formed between the top end of the charging module 21 and the top side of the chassis 1, and side air ducts 43 are formed between the two sides of the charging module 21 and the two sides of the chassis 1. The main air duct 41, the top air duct 42, and the side air ducts 43 are interconnected to form a continuous heat dissipation air duct 4.
[0041] Referring to Figure 3 , and Figure 5, on both sides of the chassis 1, side plates 13 are detachably arranged. A plurality of side air inlets 131 are formed in the side plates 13. The plurality of side air inlets 131 are uniformly arranged in an array. The side air inlets 131 communicate the side air duct 43 with the outside of the chassis 1. Thus, the cold air outside the chassis 1 can fully enter the interior of the chassis 1 from the side air inlets 131 and sufficiently dissipate heat from the charging module 21. An arc-shaped baffle 132 corresponding to each side air inlet 131 is further arranged on the outside of the side plate 13. A side dust-proof net 133 is further arranged on the side of the side plate 13 facing the interior of the chassis 1. The side dust-proof net 133 is used to cover the side air inlets 131 for filtering dust. Thus, through the mutual cooperation of the arc-shaped baffle 132 and the side dust-proof net 133, it can effectively reduce the entry of external rainwater or dust into the interior of the chassis 1 with the air from the side air inlets 131, which is beneficial to preventing the external rainwater or dust from affecting the charging mechanism 2 inside the chassis 1.
[0042] Refer to Figure 5 and Figure 6 , on the bottom of the chassis 1, a bottom plate 14 is detachably arranged. A plurality of bottom air inlets 141 are uniformly formed in the bottom plate 14. The plurality of bottom air inlets 141 are also uniformly arranged in an array. The bottom air inlets 141 communicate the main air duct 41 with the outside of the chassis 1. Thus, the cold air outside the chassis 1 can also fully enter the interior of the chassis 1 from the bottom air inlets 141, which is beneficial to further increasing the intake of cold air during the heat dissipation of the chassis 1. A bottom dust-proof net 142 is arranged on the bottom plate 14 facing the interior of the chassis 1. The bottom dust-proof net 142 is used to cover the bottom air inlets 141 for filtering dust.
[0043] Since both the side plate 13 and the bottom plate 14 are detachably designed, the user can regularly remove the side plate 13 or the bottom plate 14 and clean the dust in the side air duct 43 or the main air duct 41, reducing the dust accumulation in the heat dissipation air duct 4, which is beneficial to improving the heat dissipation efficiency.
[0044] Refer to Figure 3 , Figure 4 and Figure 5, the heat dissipation mechanism 3 includes several groups of main heat dissipation fans 31 and module heat dissipation fans 32. Among them, the module heat dissipation fan 32 is used to dissipate heat from the charging module 21, mainly to fully dissipate the heat generated by the charging module 21 into the heat dissipation air duct 4. Specifically, in this embodiment, a total of six module heat dissipation fans 32 are provided, and the six module heat dissipation fans 32 are evenly arranged at the top of the charging module 21. The module heat dissipation fan 32 communicates with the top of the charging module 21 and the top air duct 42. Further, a grille baffle 211 is erected on the top of the charging module 21, and the module heat dissipation fan 32 is located between the grille baffle 211 and the charging module 21. Since the blades of the module heat dissipation fan 32 face in the vertical direction, the grille baffle 211 can block some larger sand or debris, preventing sand and debris from falling on the module heat dissipation fan 32 and affecting the normal operation of the module heat dissipation fan 32 or the charging module 21, which is beneficial to protecting the module heat dissipation fan 32 and extending the service life of the module heat dissipation fan 32.
[0045] Refer to Figure 3 and Figure 5 , the main heat dissipation fan 31 is used to cooperate with the main air duct 41 to fully dissipate the overall heat inside the chassis 1 to the outside of the chassis 1, fully realizing the heat dissipation and cooling inside the chassis 1. Specifically, in this embodiment, a total of two main heat dissipation fans 31 are provided, and the two main heat dissipation fans 31 are respectively arranged on both sides of the chassis 1 and are located on both sides of the main air duct 41. The main heat dissipation fan 31 communicates with the outside of the chassis 1 and the main air duct 41, so that when the main heat dissipation is started, the main heat dissipation can fully dissipate the heat in the main air duct 41 to the outside of the chassis 1.
[0046] Refer to Figure 1 and Figure 6 , for the convenience of moving the mobile charger, universal wheels 15 are provided at the four diagonals on the outside of the bottom of the chassis 1, and a telescopic pull rod 16 is provided on the back of the chassis 1. Thus, the user can pull the telescopic pull rod 16 and cooperate with the universal wheels 15 to realize the free movement of the chassis 1, which is beneficial to improving the mobility and portability of the charger.
[0047] The implementation principle of a mobile charger in an embodiment of this application is as follows:
[0048] When the mobile charger is charging, the charging module 21 starts to heat up and generate heat. Since the fixed partition 12 has separated the charging module 21 and the control element group 22 into two different cavities inside the chassis 1, the heat generated by the charging module 21 has little impact on the control elements.
[0049] When the heat generated by the charging module 21 reaches a certain level, the main cooling fan 31 and the module cooling fan 32 are activated. First, the module cooling fan 32 dissipates the heat at the top of the charging module 21 into the top air duct 42, and the main cooling fan 31 dissipates the heat in the main air duct 41 to the outside of the chassis 1. At this time, due to the continuous air extraction and heat dissipation of the main cooling fan 31, the air pressure in the main air duct 41 decreases. Therefore, the hot air in the side air duct 43 and the top air duct 42 will flow fully along the heat dissipation air duct 4 into the main air duct 41 due to the air pressure. The heat generated at the top and both sides of the charging module 21 converges in the main air duct 41 along with the air flow, and finally is fully dissipated to the outside of the chassis 1 through the main cooling fan 31.
[0050] Moreover, as the overall air pressure inside the chassis 1 decreases, in order to balance the air pressure inside and outside the chassis 1, the cold air in the outside environment of the chassis 1 enters the inside of the chassis 1 fully from the side air inlet and the bottom air inlet. The newly entered cold air not only directly cools the two sides and the bottom of the charging module 21, but also makes up for the air inside the chassis 1, making the air flow inside the chassis 1 stable, which is beneficial to continuously and stably dissipate the heat of the charging module 21 for a long time.
[0051] This specific implementation manner is only an interpretation of the present application, and it is not a limitation to the present application. After reading this specification, those skilled in the art can make modifications without creative contributions to this specific implementation manner as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
