Abstract
The utility model relates to a straight flow type radiator. The straight flow type radiator comprises a lamp body and radiating pipes which are arranged under the lamp body. A plurality of heat sinks are arranged on the outer wall of the radiating pipes. All the heat sinks extend outwards along the radial direction of the radiating pipes, and heat is transmitted through the heat sinks along the length direction of the radiating pipes. Compared with the existing method of spiral-shaped circuitous heat transmission, the straight flow type radiator has the advantages of being rapid in heat transmission speed and high in efficiency. Meanwhile, gaps among the heat sinks are capable of ventilating and dissipating heat, and the whole effect of the heat dissipating is good.
