DETAILED DESCRIPTION
[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] Please refer to Figures 1-7 The heat dissipation air duct of the charger in the embodiment comprises a casing 1, a heat generating unit 2 arranged in the casing 1, an air duct assembly 3 arranged in the casing 1, and a heat transfer unit 4 arranged on the air duct assembly 3 and connected with the heat generating unit 2 through the heat transfer unit 4.
[0028] The air duct assembly 3 comprises an intermediate body 31, an air inlet cover 32 and an air outlet cover 33 arranged at two ends of the intermediate body 31 respectively, and a plurality of heat dissipation fins 34 arranged in the intermediate body 31 at equal intervals along the z-axis and symmetrically distributed along the y-axis of the intermediate body 31, and a heat transfer channel 35 formed in the intermediate body 31 between the heat dissipation fins 34.
[0029] In application, when the charger is running, the heat generating unit 2 inside the charger works to generate heat, and the heat generated by the heat generating unit 2 is transferred to the air duct assembly 3 through the heat transfer unit 4. At this time, the fan 5 is allowed to work and run. After the fan 5 runs, the fan 5 blows air into the air inlet cover 32. After the external air enters the air inlet cover 32, it passes through the heat transfer channel 35 and is discharged from the air outlet cover 33. When the external air flows in the heat transfer channel 35, the heat transferred from the heat generating unit 2 to the intermediate body 31 and the heat dissipation fins 34 is carried away by the flowing external air and discharged from the casing 1. By the above-mentioned way, when the external air flows in the regular heat transfer channel 35 in the intermediate body 31 separated by the heat dissipation fins 34, the air flow is smooth and the exhaust is smooth, so that more heat can be carried away when the air flows in the air duct assembly 3, thereby improving the heat dissipation efficiency of the charger.
[0030] It should be noted that the heat transfer channel 35 comprises a longitudinal channel, two transverse channels and a plurality of transverse branch channels. The longitudinal channel, the transverse channels and the transverse branch channels are communicated with each other. The longitudinal channel is arranged between the two transverse channels and located on the same central axis. The plurality of transverse branch channels are symmetrically arranged at equal intervals along the longitudinal channel on both sides of the longitudinal channel, and are located between the two heat dissipation fins 34. The transverse branch channel has the same width as the longitudinal channel and is smaller than the transverse channel. The above arrangement of the heat transfer channel 35 ensures that the transition of air flow from the longitudinal channel to the transverse channel is uniform, avoiding turbulence and air flow backflow. The arrangement of the plurality of transverse branch channels ensures that the air flow path in the heat transfer channel 35 is consistent, avoiding air flow obstruction caused by uneven structure. At the same time, the fan 5 is installed at the air inlet cover 32, and the blowing direction is clearly from the air inlet cover 32 to the air outlet cover 33, which ensures that the external air flows in the heat transfer channel 35 in a single direction, and the exhaust is smooth.
[0031] It can be understood that the longitudinal channel is located between the two transverse channels and communicates with the transverse channels and the transverse branch channels, and the longitudinal channel is arranged on the same central axis to ensure that the air can flow along a clear main path after entering, avoiding turbulence in the initial stage; the two transverse channels are arranged at the two ends of the longitudinal channel respectively, and the width of the two transverse channels is different from that of the longitudinal channel, and this design plays a buffering role by expanding the transverse width of the airflow path, so that the airflow is more stable when turning, avoiding backflow or turbulence caused by sudden changes in the path; the plurality of transverse branch channels are symmetrically arranged on the two sides of the longitudinal channel and located between adjacent heat dissipation fins 34, and this symmetrical distribution allows the airflow to be evenly distributed between each pair of heat dissipation fins 34 while flowing longitudinally, ensuring that the heat on the surface of the heat dissipation fins 34 can be evenly taken away, and the width of the transverse branch channels is consistent with that of the longitudinal channel, ensuring the stability of the airflow velocity and further reducing the turbulence caused by the width difference, and the plurality of transverse branch channels further separate the airflow path into regular unit channels, so that the airflow maintains consistent direction and flow rate in each unit channel, avoiding transverse interference.
[0032] Embodiment 2:

[0034] Please refer to Figures 1-6 , the length of the heat dissipation fin 34 in the embodiment is equal to the length of the intermediate body 31, the air duct assembly 3 is an integrally formed structure, the air duct assembly 3 is made of copper material, the machine shell 1 is provided with an air inlet 11 corresponding to the air inlet cover 32, the fan 5 is connected to the inner side wall of the machine shell 1 corresponding to the air inlet 11, the machine shell 1 is provided with an air outlet 12, the air outlet cover 33 is connected to the inner side wall of the machine shell 1 corresponding to the air outlet 12, and the air outlet direction of the fan 5 is from the air inlet cover 32 to the air outlet cover 33.
[0035] In application, the fan 5 runs to blow air into the air duct assembly 3 through the air inlet 11, and the external air is discharged through the air outlet 12 after flowing through the air inlet cover 32, the intermediate body 31 and the air outlet cover 33. When the external air flows in the heat transfer channel 35 in the intermediate body 31, the air duct assembly 3 is made of copper material with high thermal conductivity, so that more heat can be taken away when the external air flows, improving the heat dissipation efficiency, and the external air also contacts the plurality of heat dissipation fins 34 when flowing, the heat dissipation fins 34 can effectively increase the heat transfer area of the external air flowing in the heat transfer channel 35, further improving the heat dissipation efficiency.
[0036] It should be noted that the heat transfer channel 35 in the air duct assembly 3 is located in the intermediate body 31, and the heat transfer channel 35 has a certain distance from the air inlet 11 of the air inlet cover 32 and the air outlet 12 of the air outlet cover 33, so that the external air flowing in the heat transfer channel 35 is difficult to be affected by external factors such as dust and water vapor, improving the IP protection level.

[0038] The basic content is same as that in Embodiment 1, except that:
[0039] Please refer to Figure 1 , Figure 2 and Figure 7 , the heat transfer unit 4 in the embodiment comprises a heat conduction block 41 and a heat conduction pipe 42, the heat conduction block 41 is connected with the heat generating unit 2 and is assembled on the intermediate body 31, the intermediate body 31 is formed with a heat transfer part 36 corresponding to the heat conduction block 41, the heat conduction block 41 is formed with a first recess 43, the heat transfer part 36 is formed with a second recess 37, and the heat conduction pipe 42 is arranged in the first recess 43 and the second recess 37.
[0040] In application, the heat generating unit 2 will transmit the generated heat to the heat conduction block 41 after working, and the heat conduction block 41 will transmit the heat to the intermediate body 31, so that the external air will take away the heat when flowing in the heat transfer channel 35 in the intermediate body 31, and when the heat conduction block 41 transmits the heat, the heat will be transmitted to the heat transfer part 36 through the heat conduction pipe 42, and the heat will be transmitted to the intermediate body 31 through the heat transfer part 36, and the heat transfer rate is effectively improved through the above two heat transfer paths.
[0041] Further, the heat conduction block 41 is a copper block, the heat conduction pipe 42 is a capillary copper pipe, the heat absorbing end of the heat conduction pipe 42 is located in the first recess 43, and the heat releasing end is located in the second recess 37.
[0042] It can be understood that the heat conduction block 41 made of copper has high heat conduction coefficient and high heat transfer rate during heat transfer, and cooperates with the capillary copper pipe to transmit the heat to the intermediate body 31 more quickly.
[0043] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model.
