[0018] The embodiment of the present application provides a high-heat dissipation LLC-compatible charging module, which effectively solves the technical problem that when the charging module is working, the internal temperature will gradually increase with use, and the resistance of the internal electronic components will increase with the increase in temperature, which will lead to reduced charging efficiency. If the temperature of the LLC charging module is too high, the semiconductor refrigeration plate, the first fan, and the second fan will be started. After the semiconductor refrigeration plate is started, the side connected to the first heat sink will generate a low temperature, and the side connected to the second heat sink will generate a high temperature. The low temperature generated by the semiconductor refrigeration plate will be transferred to the first heat sink, and the first fan will start to blow external air into the shell. In this process, impurities in the air The air will be blocked by the filter, and the air will be cooled by the first heat sink when passing through the first heat sink. The cooled air can be blown into the outer shell to cool the LLC charging module. The air blown in by the first fan can be cooled by the semiconductor refrigeration sheet, so as to reduce the temperature of the LLC charging module when in use, thereby achieving the effect of avoiding the reduction of charging efficiency due to excessive temperature. When it is necessary to move, pull the stretching rod upward, and the stretching rod will drive the two L-shaped push rods to rotate. The rotation of the L-shaped push rod will push the lifting frame to slide downward to extend the universal wheel. The stretching rod will be lengthened, and the outer shell can be pulled away by the stretching rod. By pulling the stretching rod, the lifting and lowering of the universal wheel can be completed, thereby achieving the effect of easy movement.
[0019] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when the charging module is working, the internal temperature gradually increases with use, and the resistance of the internal electronic components increases with the increase in temperature, which will lead to a decrease in charging efficiency. The overall idea is as follows:
[0020] In view of the problems existing in the prior art, the utility model provides a high heat dissipation type LLC compatible charging module, comprising a shell 1, an LLC charging module 8 is fixedly installed inside the shell 1, a first heat sink 2 is fixedly installed inside the shell 1, two semiconductor cooling plates 3 are symmetrically fixedly installed at both ends of the first heat sink 2, a second heat sink 4 is fixedly installed on the two semiconductor cooling plates 3, two first fans 5 are fixedly installed inside the shell 1, two air ducts 6 are opened on the shell 1, and second fans 7 are symmetrically fixedly installed on both sides of the shell 1.
[0021] The two second heat sinks 4 are respectively located in the two air ducts 6, and the two second fans 7 are located at both ends of the two air ducts 6. Two lifting frames 12 are symmetrically slidably installed on both sides of the housing 1, and two universal wheels 13 are fixedly installed at the bottom ends of the lifting frames 12.
[0022] A stretching rod 9 is rotatably mounted on the top of the housing 1 , and L-shaped push rods 11 are symmetrically fixedly mounted on both sides of the stretching rod 9 ; the L-shaped push rods 11 are slidably connected to the lifting frame 12 , and filters 14 are symmetrically fixedly mounted on both sides of the housing 1 .
[0023] Working principle:
[0024] In the first step, the LLC charging module 8 is also integrated with a motor drive board and a temperature control main board. When in use, if the temperature of the LLC charging module 8 is too high, the semiconductor refrigeration sheet 3, the first fan 5, and the second fan 7 will be started. After the semiconductor refrigeration sheet 3 is started, the side connected to the first heat sink 2 will generate a low temperature, and the side connected to the second heat sink 4 will generate a high temperature. The low temperature generated by the semiconductor refrigeration sheet 3 will be transmitted to the first heat sink 2, and the first fan 5 will start to blow external air into the shell 1. In this process, impurities in the air will be blocked by the filter 14, and the air will be cooled by the first heat sink 2 when passing through the first heat sink 2. After the cooled air is blown into the shell 1, the LLC charging module 8 can be cooled. The high temperature generated by the semiconductor refrigeration sheet 3 will be conducted to the second heat sink 4. The two second fans 7 are started, one is forward and the other is reversed. The second fan 7 blows the external air along the air duct 6 through the second heat sink 4 to cool the semiconductor refrigeration sheet 3. The air blown in by the first fan 5 is cooled by the semiconductor refrigeration sheet 3, and the temperature of the LLC charging module 8 when in use is reduced, thereby achieving the effect of avoiding the reduction of charging efficiency due to excessive temperature.
[0025] In the second step, when it is necessary to move, pull the stretching rod 9 upwards, the stretching rod 9 will drive the two L-shaped push rods 11 to rotate, and the rotation of the L-shaped push rod 11 will push the lifting frame 12 to slide downward to extend the universal wheel 13, and stretch the stretching rod 9, so that the outer shell 1 can be pulled and slid away by the stretching rod 9. When it moves to the specified position, reset the stretching rod 9. After the stretching rod 9 is reset, the L-shaped push rod 11 will pull the lifting frame 12 to rotate upward. After the universal wheel 13 is retracted, the outer shell 1 can be used in contact with the ground. By pulling the stretching rod 9, the lifting and lowering of the universal wheel 13 is completed, thereby achieving the effect of easy movement.
[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
