Vortex generator for heat exchanger with obliquely incised vortex forming blades

摘要

The present invention is a vortex generating device for a heat exchanger of a new configuration that can increase the heat exchange efficiency of the heat exchanger by improving the vortex generating efficiency without additional cost by increasing the vortex generating efficiency even though the overall length of the vortex generating device is not extended is about The present invention is mounted on the pipe 9 through which the fluid of the heat exchanger is transferred to generate a vortex in the fluid, comprising: a metal body 10 having a single tube shape; a flange 20 protruding outward from the base end of the body 10; The inclined incision line 30 is formed to be spaced apart from the front end of the body 10 at regular intervals so as to be inclined with respect to the longitudinal direction of the body 10 to divide the front end of the body 10 into a plurality of inclined incision pieces; And it relates to a vortex generating device for a heat exchanger comprising a; and a plurality of vortex forming blades 40 formed by twisting the inclined cut piece so that one end of the inclined cut piece protrudes into the body (10).
