摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving a heat exchanging efficiency and an air conditioner provided with the heat exchanger. SOLUTION: The fin of a heat exchanger is provided with two trapezoid parts 96 protruding along an air blowing direction and flat parts 98 provided between the trapezoid parts. Therefore, a sufficient turbulence can be generated so as to break the thermal boundary layer of air relative to air flowing on the surface of the fin, and a heat exchanging efficiency can be improved. Besides, a blast resistance is not extremely increased and the heat exchanging effciency of all the heat exchanger can be improved. Further, the heat exchanger is excellent in its drainage and hardly generates frost.

摘要： PROBLEM TO BE SOLVED: To improve heat transfer characteristics by forming many grooves in an internal surface in the direction of the flow of a refrigerant, the widths of which have several values. SOLUTION: In the internal surface of a straight pipe 26A constituting a refrigerant piping 26, the number of grooves 31..., 32... is, e.g. 60 in total are formed. Herein, the bottom width B of the groove 31 is set to be 0.33mm for example, and the bottom width (e) of the groove 32 is set to be 0.48mm for example wider than the former. Both grooves 31, 32 are alternately formed. A mixed refrigerant flows spirally with the aid of a capillary phenomenon in the grooves 31, 32 adapted to the physical properties of each refrigerant on the side of an internal wall in the refrigerant piping 26, and hereby the flow of a specific refrigerant is prevented from staying. A high viscosity R134a mainly flows in the wider groove 32 while R32, R125 flow in the narrower groove 31. Accordingly, flow resistance of the R134a is reduced owing to the capillary phenomenon to reduce pressure drop whereby the mixed refrigerant flows smoothly also along the upper part in the refrigerant piping 26 to improve the heat transfer characteristics.

摘要： PURPOSE:To provide a beer dispenser from which beer can be poured out always at a suitably cooled, not too frothy state independent of the length of the interval between servings. CONSTITUTION:A beer-cooling pipe 17 inside a cooling water tank 13 and a pouring cock 2 at the front of the main casing 1, which are structurally apart from each other, are connected by a connecting pipe 23B. In this instance by putting the connecting pipe 23B in contact with the wall of the cooling water tank 13 the beer standing inside the connecting pipe 23B can be kept cool and is held ready for a serving. As a result, a first customer after a long interval can be served a beer without too much froth on it.

摘要： PURPOSE:To prevent secondary foaming of heat insulating material, which is caused when the box is used as a hot reserving chamber, by forming a heat resistant layer between an inner casing and the heat insulating material. CONSTITUTION:A metallic inner casing 2 is received in a metallic outer casing 3, opened upwardly, while the upper end rims of both of the casings 2, 3 are connected by a packing 14. A cooling pipe 6 is attached to and wound spirally around the outer surface of the side wall of the inner casing 2 while an electric heater 9 is attached to the lower surface of the bottom wall of the inner casing 2 through a heat transfer plate 8. A space between both of inner and outer casings 2, 3, excluding the bottom surface of the inner casing 2, and a bottom plate 7 is filled with foamed expandable polyurethane heat insulating material 11. A heat resistant layer 21, consisting of glass wool, is formed between the outer surface of side wall of the inner casing 2 and the heat insulating material 11. Accordingly, even when the temperature of the inner casing 2 is increased by the generation of heat of the heater 9, heat from the inner casing 2 is shielded by the heat resistant layer 21 and is hardly transferred to the heat insulating material 11 whereby the secondary foaming of the heat insulating material 11 is prevented and the generation of deformation of the heat insulating box itself can be prevented.
