[0002] A power charger is an electronic device dedicated to converting external alternating current (AC) or direct current (DC) into direct current (DC) suitable for specific rechargeable devices (such as batteries). It usually contains one or more conversion circuits, such as rectification, filtering and voltage regulation, to ensure that the output current and voltage meet the charging specifications of the device battery. The charger integrates current limiting, voltage limiting and other control circuits to ensure safe and efficient charging of the battery. The charger design is widely used in various consumer electronic products, such as smartphones, tablets, laptops, power tools, electric vehicles and other devices using rechargeable batteries. Some chargers can also support fast charging standards such as USB, PD, QC, etc., to provide higher charging speeds.

[0003] In the prior art, household power chargers usually use a fanless design in order not to generate a lot of noise that affects indoor comfort. They rely entirely on natural convection and have a larger shell surface area to increase the heat dissipation area. Although the above settings meet the usage requirements to a certain extent, there is still a problem of low heat dissipation efficiency. Utility Model Content

[0004] The utility model aims to provide a power charger with high heat dissipation safety, which has the advantages of ensuring the sealing of the shell and high heat dissipation efficiency, and solves the problem of using a fanless design for silence, completely relying on natural convection, and having low heat dissipation efficiency.

[0005] To achieve the above object, the utility model provides the following technical solution: a power charger with high heat dissipation safety, comprising a power supply mechanism, a circulation structure is fixedly installed inside the power supply mechanism, the power supply mechanism comprises a mounting shell, a cover plate is fixedly installed on the top of the mounting shell, silicone oil is filled inside the mounting shell and the cover plate, a circuit board is fixedly installed inside the mounting shell, a heat dissipation fin is fixedly installed on the top of the circuit board, and the outer walls of the mounting shell and the cover plate are both provided with heat dissipation patterns;

[0006] The circulation structure includes a silent circulation pump, a liquid inlet pipe is fixedly installed on one side of the silent circulation pump, a liquid outlet pipe is fixedly installed on one side of the silent circulation pump, a flow meter is fixedly installed inside the liquid inlet pipe, and a filter is fixedly installed at one end of the liquid inlet pipe.

[0007] As a preferred power charger with high heat dissipation safety of the utility model, a pressure sensor is fixedly installed on the bottom of the cover plate, and a temperature sensor is fixedly installed on the bottom of the cover plate.

[0008] As a preferred power charger with high heat dissipation safety of the utility model, a pressure relief valve is fixedly installed on the top of the cover plate, and two sets of liquid replacement valves are fixedly installed on one side of the mounting shell.

[0009] As a preferred power charger with high heat dissipation safety of the utility model, an input terminal is fixedly installed on one side of the mounting shell, an output terminal is fixedly installed on one side of the mounting shell, and a plurality of expansion interfaces are fixedly installed on one side of the mounting shell.

[0010] As a preferred power charger with high heat dissipation safety of the utility model, a handle is fixedly mounted on one side of the mounting shell.

[0011] As a preferred power charger with high heat dissipation safety of the utility model, an independent switch is fixedly installed on one side of the mounting shell, a current adjustment knob is rotatably installed on one side of the mounting shell, and a voltage adjustment knob is rotatably installed on one side of the mounting shell.

[0012] As a preferred power charger with high heat dissipation safety of the utility model, a display panel is fixedly mounted on the top of the mounting shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The silent circulation pump of the utility model makes the silicone oil circulate inside the mounting shell and the cover plate through the cooperation between the liquid inlet pipe and the liquid outlet pipe. The circulating silicone oil absorbs the heat of the heating element of the circuit board and dissipates the heat through the natural convection or radiation of the outer wall of the mounting shell and the cover plate to complete the heat cycle. In this process, the heat exchange area of ​​the circuit board and the silicone oil is increased by the heat dissipation fins to improve the heat absorption efficiency of the silicone oil. The surface area of ​​the mounting shell and the cover plate is increased by the heat dissipation pattern to increase the efficiency of the natural convection or radiation heat dissipation of the outer wall of the mounting shell and the cover plate. The flow rate of the silicone oil is monitored by the flow meter to ensure the stable operation of the heat dissipation system. The working state of the pump can be automatically adjusted when necessary, and the impurities in the silicone oil are filtered through the filter to prevent debris from damaging the internal structure of the silent circulation pump.

[0015] Because the thermal conductivity and specific heat capacity of silicone oil are much higher than those of air, the heating element is completely immersed in the cooling oil, and the contact area with the silicone oil is larger. Unlike air cooling, heat is not transferred only through the heat sink, nor is it limited by the contact area of ​​the water cooling head like water cooling, thereby improving the heat transfer efficiency. The above-mentioned heat dissipation system does not rely on forced convection heat dissipation methods such as fans, so it can achieve nearly silent operation. At the same time, due to the absence of the thermal boundary layer effect of the fan in air cooling, the heat transfer efficiency will be higher in theory. In summary, the device has low noise and the heat exchange efficiency is not inferior to traditional air cooling, and has the advantages of low noise and high heat dissipation efficiency.

DETAILED DESCRIPTION

[0021] See also Figure 1-4 A power charger with high heat dissipation safety comprises a power supply mechanism 1, a circulation structure 2 is fixedly installed inside the power supply mechanism 1, the power supply mechanism 1 comprises a mounting shell 101, a cover plate 102 is fixedly installed on the top of the mounting shell 101, silicone oil 103 is filled inside the mounting shell 101 and the cover plate 102, a circuit board 104 is fixedly installed inside the mounting shell 101, a heat dissipation fin 105 is fixedly installed on the top of the circuit board 104, and the outer walls of the mounting shell 101 and the cover plate 102 are provided with heat dissipation patterns 106;

[0022] The circulation structure 2 includes a silent circulation pump 201, a liquid inlet pipe 202 is fixedly installed on one side of the silent circulation pump 201, a liquid outlet pipe 203 is fixedly installed on one side of the silent circulation pump 201, a flow meter 204 is fixedly installed inside the liquid inlet pipe 202, and a filter screen 205 is fixedly installed at one end of the liquid inlet pipe 202;

[0023] During use, the silent circulation pump 201 makes the silicone oil 103 circulate inside the mounting shell 101 and the cover plate 102 through the cooperation between the liquid inlet pipe 202 and the liquid outlet pipe 203. The circulating silicone oil 103 absorbs the heat of the heating element of the circuit board 104, and dissipates heat through natural convection or radiation of the outer wall of the mounting shell 101 and the cover plate 102 to complete the thermal cycle. In this process, the heat exchange area of ​​the circuit board 104 and the silicone oil 103 is increased by the heat dissipation fins 105 to improve the heat absorption efficiency of the silicone oil 103. The surface area of ​​the mounting shell 101 and the cover plate 102 is increased by the heat dissipation pattern 106, and the efficiency of natural convection or radiation heat dissipation of the outer wall of the mounting shell 101 and the cover plate 102 is increased. The flow rate of the silicone oil 103 is monitored by the flow meter 204 to ensure the stable operation of the heat dissipation system. The working state of the pump can be automatically adjusted when necessary, and the impurities in the silicone oil 103 are filtered through the filter 205 to prevent debris from damaging the internal structure of the silent circulation pump 201.

[0024] Because the thermal conductivity and specific heat capacity of silicone oil 103 are much higher than those of air, the heating element is completely immersed in the cooling oil, and the contact area with the silicone oil 103 is larger. Unlike air cooling, heat is not transferred only through the heat sink, nor is it limited by the contact area of ​​the water cooling head like water cooling, thereby improving the heat transfer efficiency. The above-mentioned heat dissipation system does not rely on forced convection heat dissipation methods such as fans, so it can achieve nearly silent operation. At the same time, due to the absence of the thermal boundary layer effect of the fan in air cooling, the heat transfer efficiency will be higher in theory. In summary, the device has low noise and the heat exchange efficiency is not inferior to traditional air cooling, and has the advantages of low noise and high heat dissipation efficiency.

[0025] Furthermore, a pressure sensor 109 is fixedly installed at the bottom of the cover plate 102, and a temperature sensor 110 is fixedly installed at the bottom of the cover plate 102;

[0026] During use, the pressure sensor 109 monitors and records the pressure data in the entire liquid cooling system to ensure that the coolant is always kept within a safe pressure range during the circulation process. Too high or too low pressure may cause system failure or component damage, and the temperature sensor 110 monitors the temperature of the liquid to ensure stable operation of the cooling system.

[0027] Furthermore, a pressure relief valve 107 is fixedly installed on the top of the cover plate 102, and two sets of liquid replacement valves 108 are fixedly installed on one side of the mounting shell 101;

[0028] During use, the pressure relief valve 107 releases excessive pressure inside the mounting shell 101 and the cover plate 102 to prevent the mounting shell 101 and the cover plate 102 from being too high. At the same time, the liquid replacement valve 108 facilitates the staff to replace the silicone oil 103.

[0029] Furthermore, an input terminal 111 is fixedly installed on one side of the installation shell 101, an output terminal 112 is fixedly installed on one side of the installation shell 101, and a plurality of expansion interfaces 113 are fixedly installed on one side of the installation shell 101;

[0030] During use, the device is connected to the mains power grid through the input terminal 111 and connected to the device to be charged through the output terminal 112 to achieve charging. At the same time, the device is more extensible through several expansion interfaces 113.

[0031] Furthermore, a handle 114 is fixedly mounted on one side of the mounting shell 101;

[0032] The handle 114 increases the portability of the device during use.

[0033] Further, an independent switch 115 is fixedly mounted on one side of the mounting shell 101, a current adjustment knob 116 is rotatably mounted on one side of the mounting shell 101, and a voltage adjustment knob 117 is rotatably mounted on one side of the mounting shell 101;

[0034] During use, the power supply is individually controlled by the independent switch 115, without having to plug and unplug the power cord every time. This not only avoids the wear of the socket caused by frequent plugging and unplugging, but also provides a quick way to cut off the power supply in an emergency, which is conducive to safe use of electricity. The output voltage and current of the device can be adjusted by the current adjustment knob 116 and the voltage adjustment knob 117.

[0035] Furthermore, a display panel 118 is fixedly mounted on the top of the mounting housing 101;
