The volume of the first radiating fin 450a is larger than the volume of the second radiating fin 450b.

Specifically, the thickness d2 of the first radiating fin 450a is thicker than the thickness of the second radiating fin 450b, and the height d1 of the first radiating fin 450a is higher than the height of the second radiating fin 450b. Here, the height d1 of the first radiating fin 450a means the length in the outward direction from the side surface of the heat discharging body 400. The first radiating fins 450a and the second radiating fins 450b on the side surface of the heat discharging body 400 are reduced in height d1 from the upper surface of the heat discharging body 400 in the lower direction. The height d1 of the first radiating fins 450a may be 7 mm or more and 12 mm or less and the thickness d2 of the first radiating fins 450a may be 1 mm or more and 2 mm or less. Preferably, the height d1 of the first radiating fin 450a is 10 mm and the thickness d2 of the first radiating fin 450a is 1.5 mm.

The thickness d2 of the first radiating fins 450a may become thinner from the upper surface of the heat discharging body 400 toward the lower side as shown in Fig. In this case, the two side surfaces facing each other in the first radiating fin 450a are closer to each other as they descend from the upper surface of the heat discharging body 400 to the lower surface. Here, the angle between the two sides of the first radiating fin 450a may be 1 degree or more and 1.5 degrees or less. Preferably, the angle between the two sides of the first radiating fin 450a may be 1.2 degrees. If the thickness d2 of the first radiating fin 450a is reduced from the upper surface of the heat discharging body 400 to the lower surface thereof, the heat dissipating body 400 may be advantageous in the metal mold process.

The first radiating fins 450a and the second radiating fins 450b are spaced apart from each other and are disposed on the side surface of the heat discharging body 400 in plurality. The first radiating fins 450a and the second radiating fins 450b are alternately arranged on the side surface of the heat discharging body 400. [ That is, the second radiating fins 450b are disposed between the two first radiating fins 450a and the first radiating fins 450a are disposed between the two second radiating fins 450b. The distance between the first radiating fins 450a and the second radiating fins 450b may be 1 mm or more and 3 mm or less. Here, the gap between the first radiating fin 450a and the second radiating fin 450b may be 2 mm.

If the heat dissipating member 400 has the first heat dissipating fin 450a and the second heat dissipating fin 450b, it is possible to improve the heat dissipating efficiency and advantages advantageous in the mold process and the coating process during the manufacturing process of the heat dissipating member 400. [ If the heat dissipator 400 has only the first heat dissipation fin 450a without the second heat dissipation fin 450b, it is difficult to coat the mold with the heat dissipator 400 at the time of manufacturing the heat dissipator 400. [ On the other hand, when the heat discharging body 400 has only the second heat radiating fin 450b, the heat radiating area of the heat discharging body 400 is reduced.
