[0052] In the embodiment, the shell 1 of the water cooling liquid cooling system 100 is used for installing, fixing and protecting the cooling structure 2, the liquid storage structure 3, the liquid block assembly 4 and the like, that is, the shell 1 provides an installation basis for the cooling structure 2, the liquid storage structure 3, the liquid block assembly 4 and the like. It can be understood that the shell 1 can be a box body, a box body, an installation shell, an installation rack or a support structure, which is not limited here.

[0053] Optionally, the installation cavity and the fixing cavity 15 are formed in the shell 1 and arranged adjacently, so that the cooling structure 2 can be installed, fixed and protected by using the installation cavity of the shell 1, and the liquid storage structure 3 and the liquid block assembly 4 can be installed and fixed by using the fixing cavity 15.

It can be understood that the fan 221 of the fan assembly 22 can be a hair dryer structure, which is not limited here.

[0055] Of course, in other embodiments, the roles of the first air outlet 131 and the second air outlet 124 can also be exchanged, that is, the first air outlet 131 blows air, and the second air outlet 124 draws air, at which time the fan 221 of the fan assembly 22 can be a suction fan structure, which is not limited herein. It can be understood that the first air outlet 131 and / or the second air outlet 124 are provided with a grille to form a plurality of small holes with the grille, which can achieve both ventilation and heat dissipation and protection with the grille, which is not limited herein.

[0056] In order to increase the air outlet area and improve the heat dissipation and cooling efficiency of the heat dissipation plate 21, the size and profile of the second air outlet 124 are equivalent to the size of the heat dissipation surface of the heat dissipation plate 21, and the heat dissipation surface of the heat dissipation plate 21 is opposite to the second air outlet 124. Alternatively, the heat dissipation plate 21 has two heat dissipation surfaces arranged away from each other and a peripheral side surface between the two heat dissipation surfaces, at which time one heat dissipation surface of the heat dissipation plate 21 is opposite to the second air outlet 124, and the other heat dissipation surface is opposite to the fan assembly 22. In this way, it can be ensured that the cold air drawn in by the fan assembly 22 from the first air outlet 131 fully contacts the two large heat dissipation surfaces and is blown out through the second air outlet 124, which is not limited herein.

At the same time, by using at least two small fans 221, it can not only reduce the size of the device, but also ensure the cooling air volume of the entire machine and improve the cooling efficiency. In this way, the cooling medium flows between the gun wire of the charging gun 700 and the heat dissipation plate 21, and the heat generated during charging of the charging gun 700 is taken away by the fan assembly 22.

[0091] It can be understood that the two ends of the cooling channel of the charging gun 700 are communicated with the liquid inlet flow channel 411 and the liquid return flow channel 412 respectively, so that the cooling channel of the charging gun 700 cooperates with the liquid return flow channel 412, the cooling flow channel, the liquid storage cavity and the liquid inlet flow channel 411 of the water cooling liquid cooling system 100 to form a cooling liquid channel for circulating the cooling medium, so that the water cooling liquid cooling system 100 is used to control the cooling structure flowing through the cooling channel of the charging gun 700, so as to realize the cooling of the charging gun 700, thereby improving the service life and charging efficiency of the charging gun 700.
