An axial rotary heat pipe grinding wheel is a new type of grinding wheel used to strengthen the heat transfer in the grinding arc area. Its heat transfer performance directly affects the heat transfer performance of the entire heat pipe grinding wheel. In this study

the condenser of the heat pipe grinding wheel was designed in conjunction with the condenser design method

and the heat transfer performance of the axial rotating heat pipe grinding wheel condenser was analyzed using a numerical simulation model to optimize the structural parameters of the condenser of the rotating heat pipe grinding wheel. The effects of different fin heights (f = 0–8 mm)

nozzle-to-fin top distances (d = 3–11 mm)

low-temperature air jet velocities (vj = 45–115 m/s)

and grinding wheel speeds (n = 150–1 180 r/min) on the heat transfer performance of the condenser were investigated. The results showed that the best heat transfer coefficient of 459 W/(m2·K) was obtained when the fin height was 6 mm

in which the convective heat transfer coefficient was increased by 36% compared with the finless structure. The best heat transfer performance was obtained when the distance from the nozzle to the top of the fin was 5 mm

and the heat transfer coefficient was 459 W/(m2·K). When the low-temperature air jet velocity increases

the convective heat transfer coefficient increases. The highest heat transfer coefficient is achieved at a jet velocity of 115 m/s

up to 459 W/(m2·K)

which is 43% higher compared to the jet velocity of 45 m/s. When the grinding wheel speed increases

the convective heat transfer coefficient also increases. The highest heat transfer coefficient is achieved at a speed of 1 180 r/min

up to 459 W/(m2·K)

which is 4% higher than the speed of 150 r/min.
