This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0028] In the description of the utility model, if there is a description of quantity, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of first or second, it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] like Figures 1 to 10 As shown, the utility model discloses a mobile phone cooling device, comprising a radiator body 1, a cooling column 2 arranged at one end of the radiator body 1, and a magnetic ring assembly 3 which is sleeved on the outer periphery of the cooling column 2 and can move axially along the cooling column 2, a lifting and limiting mechanism is arranged between the magnetic ring assembly 3 and the cooling column 2, a cooling part is arranged at one end of the cooling column 2 away from the radiator body 1, and a cooling mechanism for cooling the cooling part is arranged inside the cooling column 2.

[0031] When the mobile phone is mounted on the magnetic ring bracket 8, it is necessary to move the magnetic ring assembly 3 to the position where it fits with the radiator body 1. At this time, the heat dissipation column 2 is in a protruding state, so that the heat dissipation column 2 can be passed through the magnetic ring bracket 8 and fit with the mobile phone. At this time, the magnetic ring assembly 3 of the mobile phone heat dissipation device will be adsorbed together with the bracket, thereby realizing the fixation of the mobile phone heat dissipation device and the mobile phone, and then the heat dissipation part of the mobile phone that fits is effectively dissipated through the heat dissipation mechanism, thereby achieving the effect of cooling the mobile phone; when the mobile phone is not installed on the mobile phone bracket for use, it is necessary to move the magnetic ring assembly 3 to the end away from the radiator body 1 so that it is flush with the end face of the free end of the heat dissipation column 2, so that the magnetic ring assembly 3 can be directly adsorbed and fixed to the magnetic part on the back of the mobile phone, thereby achieving the effect of cooling the mobile phone.

[0032] The mobile phone described in the utility model can be a mobile phone with a magnetic attraction portion on the back of the mobile phone, and the magnetic attraction portion can be a magnetic attraction portion provided by the mobile phone or a magnetic attraction portion pasted on the back of the mobile phone.

In this embodiment, a limiting protrusion 25 capable of blocking the slider is also provided at the upper and lower ends of the spiral groove, respectively, to play a role of rotation limiting.

[0035] In some embodiments, the lifting and limiting mechanism may also be a linear guide structure, and the magnetic ring assembly 3 may cooperate with the heat dissipation column 2 through the linear guide to achieve axial movement. Of course, other lifting and limiting mechanisms that can achieve axial movement are not excluded.

[0036] In the present invention, the heat dissipation mechanism includes a cooling sheet 22 attached to the inner side of the heat dissipation part.

In this embodiment, the wireless charging coil 23 is also electrically connected to the circuit board 14, and its circuit for the wireless charging function is integrated on the circuit board 14. Since the circuit board 14 also generates heat when working, and its circuit is arranged between the cooling fan 13 and the wind shield plate 15, the circuit board 14 can also be cooled by the wind blown by the cooling fan 13.

[0042] In the present invention, a connecting column is provided in the shell 11 , the periphery of the heat dissipation column 2 is connected to the connecting column of the shell 11 by screws, and the heat dissipation profile 12 , the fan and the circuit board 14 are all pressed and fixed between the heat dissipation column 2 and the shell 11 .
