Heat radiator

The invention discloses a radiator, which comprises a base plate, radiating fins consisting of fins and a fan arranged on the upper end surfaces of the radiating fins. The upper end surfaces of the radiating fins and the base plate have slopes with included angles. The included angle between one of the upper end surfaces of the radiating fins and the base plate is between 10 DEG and 45 DEG. In the radiator, the upper end surfaces of the radiating fins are designed to be oblique, thereby greatly optimizing the wind cooling passage of the radiator. The invention has the advantages that the spacing between the panel of a casing and the radiator is very small, the obliquely installed fan can reduce wind resistance, ensure sufficient cool air enters the radiating fins, and avoid the formation of circulation of hot air stream again. Experiments prove that the radiating power of the radiator can reach up to 110 W, and completely meet the radiating requirements of a current CPU.
