Side blowing type heat radiator

The utility model relates to a side blowing type heat radiator, which is mainly composed of a heat radiation seat, an outer frame, and a fan locked and fixed on a panel of the outer frame, wherein, the heat radiation seat comprises a base, a locating cover, and a complex number of heat radiation fins, and the complex number of the heat radiation fins are partially overlapped and staggered; interstices are formed among the heat radiaton fins, and the locating cover is arranged above the overlapped and staggered heat radiation fins; the outer frame is arranged on a lateral part of an overlapped and staggered point of each heat radiation fin, and the fan is vertically arranged at the outer side of the overlapped and staggered point of the heat radiation fins; then a rotating air current can be concentrated to a large quantity and can pass in parallel through the interstices of the heat radiation fins, and additionally, the utility model is provided with the heat radiation seat with a side blocking structure, which can effectively stop and block the air current. Therefore, the cooling function and the heat radiation efficiency are improved.
