[0028] The following is combined with Figure 1-4 This application is described in further detail.
[0029] The embodiment of the present application discloses a liquid-cooled charging gun. Figure 1 The liquid-cooled charging gun includes a water system, which includes an inlet water channel 1, at least two outlet water channels 2 and a circulation part 3. The inlet water channel 1 is arranged between the outlet water channels 2, and the water inlet end of the inlet water channel 1 is connected to the water outlet end of the outlet water channel 2 through the circulation part 3, and the water outlet end of the inlet water channel 1 is connected to the water inlet end of the outlet water channel 2; the water flows along the water inlet end of the inlet water channel 1 to the water outlet end of the inlet water channel 1, and then flows out of the water outlet end of the outlet water channel 2 through the water inlet ends of the outlet water channels 2 on both sides, and then flows into the water inlet end of the inlet water channel 1 through the circulation part 3 to form a circulating water channel.
[0030] After passing through the water inlet channel 1, the water flows along the water outlet channel 2 to the circulation part 3, and then flows from the circulation part 3 into the water inlet channel 1 to form a water circulation, so that the various parts inside the charging gun are water-cooled, so as to achieve a better cooling effect and ensure safety.
[0031] In some embodiments, two outlet waterways 2 are provided, symmetrically arranged on either side of the inlet waterway 1, with the inlet waterway 1 and the outlet waterway 2 not coplanar. This non-coplanar arrangement allows space between the two outlet waterways 2 for other components, such as cables. This arrangement also allows for more efficient cooling of all parts of the charging gun, achieving uniform cooling within the gun.
[0032] In some embodiments, the water inlet end of the water inlet circuit 1 is connected to two water inlet pipes 4, and the circulation unit 3 is arranged corresponding to the water inlet pipes 4. That is, the number and position of the circulation units 3 are arranged corresponding to the water inlet pipes 4. The two water inlet pipes 4 are connected to the water outlet ends of the two water outlet circuits 2 through the corresponding circulation units 3. The cooperation between the circulation unit 3 and the water inlet pipes 4 makes the water flow more stable and uniform, and the water flow is distributed more efficiently, thereby achieving better cooling and improving cooling efficiency.
[0033] Reference Figure 2 In some embodiments, a connecting piece 5 is provided between the circulation part 3 and the water inlet pipe 4, and a connecting hole 6 is opened in the circulation part 3. The connecting hole 6 is connected to the connecting piece 5, and the other end of the connecting piece 5 is connected to the water inlet pipe 4 to connect the circulation part 3 and the water inlet pipe 4. In this embodiment, the connecting hole 6 is opened vertically, and the connecting piece 5 and the water inlet pipe 4 are connected in the horizontal direction.
[0034] In some embodiments, the connection position between the water inlet pipe 4 and the corresponding circulation part 3 is located in the middle section of the circulation part 3, that is, the connecting piece 5 in this embodiment is connected to the middle section of the circulation part 3, so that the water flow can be mixed and flowed in the circulation part 3, making the water flow more uniform and then flowing into the water pipe along the circulation part 3, so as to improve the cooling efficiency.
[0035] Reference Figure 3 In some embodiments, the liquid-cooled charging gun further includes a water collecting member 7. The water inlet pipe 4 is connected to the water collecting member 7, and the other end of the water collecting member 7 is connected to the water inlet channel 1. The water collecting member 7 can evenly mix the water flows on both sides before entering the water inlet pipe, thereby achieving more uniform cooling.
[0036] In some embodiments, the water inlet pipe 4 and the water inlet channel 1 are both sealed and screwed to the water collecting member 7, and the seal can be sealed by a sealing ring or the like, so as to facilitate the installation of the water inlet pipe 4 and the water inlet pipe while ensuring the sealing.
[0037] Reference Figure 4 In some embodiments, the liquid-cooled charging gun further includes a shell 8 , and the water system is disposed inside the shell 8 .
[0038] In some embodiments, the liquid-cooled charging gun uses an electronic lock, which not only improves the safety and convenience of the charging process but also facilitates intelligent management.
[0039] The implementation principle of a liquid-cooled charging gun in an embodiment of the present application is: water flows along the water inlet channel 1 and then flows out from the water outlet channel 2, flows into the water inlet channel 1 through the circulation part 3 to form a circulating water channel, and water cooling can be performed on various parts of the liquid-cooled charging gun, so that the charging gun can better dissipate heat and better ensure safety.
