Efficient heat energy exchange device

The invention discloses an efficient heat energy exchange device, which is characterized in that a heat energy exchanger is positioned at the air suction hole of a fan; the air outlet of the fan is provided with a single flow guide body; the single flow guide body is conical; the small end of the cone is over against the fan blades of the fan; the flow direction of wind is changed by using the single flow guide body; the single flow guide body can have a solid structure or be conical with a hole on the middle part or be hollow and conical; and the cone of the single flow guide body is one of a linear cone or a convex curved cone or a concave curved cone. The efficient heat energy exchange device has the advantages that wind power is guided out successfully, the air blowing range is expanded, and the radiating performance of a radiator is enhanced.
