摘要： PURPOSE:To increase the movement of fluid between neighboring flow paths and permit highly efficient heat transfer by a method wherein the area ratio of a through-hole with respect to first heat transfer body is changed in accordance with the relative position of the hole with respect to second heat transfer body. CONSTITUTION:When the flow amount and total pressure of fluid, flowing through an expanded flow path and a narrowed flow path, are supposed to be constant, a pressure difference is generated between one surface side and the other surface side of the same part of a fin 1, bent so as to have truncated wavy form, suction and blow-out of the fluid are realized through the through-hole 2 to obtain good heat transfer promoting effect and a boundary layer is re-developed in the heat transfer surface at the blow-out section starting from the bent section of the fine 1, therefore,, the heat transfer promoting effect, having the same degree substantially as the same in the suction section, is obtained. When the fluids flowing through the expanded and narrowed flow paths, collide against a pipe 3, stream at the back side of the pipe 3 is stagnated, a dead water area 6 is generated and heat transfer characteristic therein is deteriorated extremely as compared with the same in the other area. Accordingly, the number of through-holes 2 in the part corresponding to the dead water area 6 is increased to increase the pressure difference between neighboring expanded and narrowed flow paths and promote the movement of the fluid whereby more prominent heat transfer characteristic may be obtained.

摘要： PURPOSE:To improve heat transfer coefficient by a method wherein respective through- holes for heat transfer fluid, flowing from expanded flow paths toward narrowed flow paths, are formed by raised-slotted pieces, extruded toward the outlet side of the fluid and provided with specified directions. CONSTITUTION:The sectional area of the expanded flow path 4 is larger than the same of the narrowed flow path 5, therefore, the flow speed of the fluid, flowing through the expanded flow path 4, becomes lower than the same, flowing through the narrowed flow path 5, whereby the heat transfer fluid flows from the expanded flow path 4 into the narrowed flow path 5 through respective through holes 2 and flows along the bridged raised-slotted pieces 2a toward the arrow sign direction in the diagram. The bridged raised-slotted pieces 2a are formed so as to be protruded toward the outlet port side of the fluid to permit the passing of the fluid therethrough, therefore, the flow of the heat transfer fluid may be induced surely and temperature boundary layers, generated on the surface of respective heat transfer plates, may be thinned to increase the heat transfer coefficient thereof. The total surface area of respective bridged raised-slotted pieces 2a is added to the surface area of the heat exchanger, therefore, reduction of heat exchanging area may be prevented as compared with the case wherein only the through holes are equipped on the heat transfer plates.

摘要： PURPOSE:To shorten the length of each heat transfer plate in the flow direction of fluid without spoiling heat transfer promoting effect by a method wherein bent wall sections of respective heat transfer plates for forming the enlarge flow paths and narrowed flow paths of respective flow branching paths are bent into a direction orthogonal to the flow direction of the fluid. CONSTITUTION:The flow branching paths A1, A2 are arranged opposingly so that the sectional area thereof are changed along the flow direction of fluid flowing through the branching flow paths and consist of a plurality of heat transfer plates 1a, 1b, 1c having multiple through holes respectively so that the heat transfer fluid, passing through the through holes 2, is generated therein by a pressure difference between the enlarged flow path 4 and the narrowed flow path 5, which are formed back to back in respective flow branching paths. The bent wall sections 3 of respective heat transfer plates 1a, 1b, 1c are formed by bending to a direction orthogonal to the flow direction of fluid passing through respective flow branching paths. As a result, the lengths of respective heat transfer plates in the flow direction of fluid may be shortened without spoiling heat transfer promoting effect.
