The concave-convex spiral inner wall is utilized, so that the heat exchange surface area of the pore channel is greatly increased, and the actually measured heat exchange area is increased by 60%; the flow velocity of the vapor or liquid material in the pore channel is increased by several times, the original laminar flow is changed into turbulent flow, and the motion of material particles is changed from the original linear motion into spiral curve motion, so that the curvature correction is increased, and the turbulent flow effect is further enhanced; thereby effectively improving the heat transfer efficiency of the water side. Meanwhile, the deposition of material scale is slowed down by adjusting the flow speed to be high and the spiral curve motion.
The technical proposal is further improved and refined, and the graphite block is blocky or columnar.
The technical scheme is further improved and refined, a plurality of longitudinal ducts are arranged in a matrix, a plurality of transverse ducts are arranged in a matrix, and the longitudinal ducts and the transverse ducts are alternated.
A graphite heat exchanger comprises a body, wherein a graphite block is fixedly arranged in the body; the graphite block is the graphite block; the heat exchange efficiency of the heat exchanger is effectively improved.
The invention has the advantages of reasonable design and ingenious conception, increases the heat exchange area and turbulence by utilizing the concave-convex spiral inner wall, effectively improves the heat exchange efficiency of the graphite block, and simultaneously slows down the deposition of material scales in the pore channel.
