PURPOSE:To increase heat transmitting efficiency by a method wherein a choking plate, opposing to the surface of a body to which the heat is transmitted, is provided between an injecting port and a discharging port with a small interval. CONSTITUTION:The fluid choking plate D, opposing to the surface C of the body, to which the heat is transmitted, is provided between the injecting port A and the discharging port B with a small gap. The width of the air flow path between the injecting port A and the discharging port B is more than three times of the opening width of the injecting port conventionally, however, it is choked to less than two times, for example, of the opening width of the injection port, whereby a fluidic body flowed through the path except the neighborhood of the boundary film between the fluid and the body to which the heat is transmitted before is flowed forcibly to the vicinity of the boundary film to increase the flow speed near the boundary film. According to this method, destruction of the boundary film is promoted and the heat transmitting efficiency may be increased. Turbulent eddy or the like, which were occuring immediately below the discharging port before by the mutual collison of streams from both sides injecting ports A, may be approached to the boundary film positively by choking the flow path and the heat transmitting efficiency may be increased by promoting the destruction of the boundary film. |
