Abstract: The present invention flow rollers are a moving surface boundary layer control method that can reduce surface friction in, automobiles, aircrafts, ships, high speed trains, launch vehicles, sound barriers, temperature barriers, and housings. In a moving surface airflow control system, a flow roller device for mounting on a vehicle for reducing fluid resistance has a first elongated rotating body mounted on a first axis of rotation. The first axis of rotation defines a first forward portion and a first rear portion. The first forward portion is in front of the first axis of rotation, and the first rear portion is behind the first axis of rotation. The first forward portion is configured to move with the fluid flow in a direction along a longitudinal midline and rotate with the airflow.

Abstract: A seat cushion with a rapid cooling and heating function comprises a hollow cushion body (1). The hollow cushion body (1) is provided with an air-inlet hole (11) and made of a breathable material. The air-inlet hole (11) is connected with a gas-guide tube (2), and a front end of the gas-guide tube (2) is provided with a seal cover (3). The seal cover (3) is formed by a conical spring (31) and an outer cover cloth (33), and a first clamp (35) is fixed to an end of the conical spring (31). The hollow cushion body (1) is internally provided with an atmolysis device (4), the atmolysis device (4) is formed by an atmolysis block (41) and a group of atmolysis pipes (43), air-outlet ends of the group of atmolysis pipes (43) are respectively arranged in each area of the hollow cushion body (1).
