The multiple heat dissipation on the outer surface of i丨 increases the heat dissipation area of 1-1 to help dissipate heat and improve the overall heat dissipation effect. If the manufacturer wants to remove the case i, it will be repaired by manual method. The cover 3 can also be directly replaced with another spare casing 1 to effectively reduce the degree of work and cost of the group f unloading or phase lion repair, cleaning and elimination, and thus achieve a wide range of practicality. The effect.
