The present disclosure discloses a heat dissipation mechanism of the mobile terminal and a mobile terminal having the heat dissipation mechanism. In certain embodiments, the heat dissipation mechanism includes: a shell defining at least one heat dissipation window and a moving part connected with the shell. The moving part is used for by a user to open or close the at least one heat dissipation window. The heat dissipation mechanism may be used to effectively reduce surface temperature of the mobile terminal while the mobile terminal is in operation. Such a dissipation mechanism of the mobile terminal is suitable for mobile terminals and meets the demand for relatively high power consumption, ultra-thinness and miniaturization of the mobile terminals.
