The appearance of this fish tank heating rod is inspired by the high-performance graphics card shape and adopts the form of streamlined horizontal mecha. The hollow ribs of the fuselage and the front fan grille restore the language of the graphics card heat dissipation module to optimize the convection heat transfer of the water body. Matte black with gold logo, both heat dissipation practicability and identification, jump out of the traditional heating rod shape, realize the integration of function and hard core industrial aesthetics, with intelligent controller and fish tank built-in temperature display probe, real-time display of fish tank temperature and TDS value.
