The invention relates to a heating heat dissipation system with a wide action range for intelligent housing. The heating heat dissipation system comprises a heating heat dissipation device, the heating heat dissipation device comprises a frame, a back plate, a water inlet pipe, a water outlet pipe, an air inlet mechanism, a direction adjusting mechanism and two driving chambers, the direction adjusting mechanism comprises a direction adjusting assembly and two driving assemblies, the direction adjusting assembly comprises a plurality of connecting rods and a plurality of direction adjusting units, the air inlet mechanism comprises a plurality of air inlet assemblies, and each air inlet assembly comprises an air inlet pipe, a first motor, a telescopic unit and two cleaning units. Accordingto the heating heat dissipation system with the wide action range for intelligent housing, external air is introduced through the air inlet mechanism, the air is concentrated to the side, away from the wall, of equipment through the back plate, so that heat is prevented from being close and moving towards the wall direction; the air circulation is guaranteed through the cleaning units, so that theheat supply effect is improved; and moreover, the air flow direction is guided through the direction adjusting mechanism, so that hot air is uniformly distributed in a room, the heat supply range ofthe equipment is expanded, and the practicability of the system is improved.
