Abstract: PROBLEM TO BE SOLVED: To provide an electronic cold-hot storage using a thermoelectric converter. SOLUTION: This electronic cold-hot storage comprises a cooling chamber 19 cooled by exchanging heat with a heat absorbing face 23a of the thermoelectric converter 23, and a heating chamber 20 heated by exchanging heat with a heat radiating face 23 of the thermoelectric converter 23 provided with the heat absorbing face 23a for cooling the cooling chamber. Cooling of the cooling chamber 19 and heating of the heating chamber 20 is performed by one thermoelectric converter 23. The applied number of thermoelectric converters 23 is thereby reduced to attain the reduction of a material cost and miniaturization. Since the waste heat of the cooling chamber 19 is used for heating the heating chamber 20, energy is effectively used. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a manifold incorporating a thermoelectric module having Peltier effect and excellent in heat exchanging effect by limiting the movement of a stirring member in the cavity thereby ensuring an air gap where a heat carrier exists between the blade part of the stirring member and the heat transfer surface of the thermoelectric module. SOLUTION: A thermoelectric module 7 is built in a manifold body 17 fitted with a stator 17. The manifold body 17 comprises a heating side manifold 2 and a cooling side manifold 3 arranged, respectively, with a heating side stirring member 5 and a cooling side stirring member 6. Shafts 12, 23 are inserted into bearing members 15f, 25f of the stirring members 5, 6. Stop parts 28, 32 are caulked to the forward end of the shaft 12.

Abstract: PROBLEM TO BE SOLVED: To obtain a manifold which incorporates a thermoelectric module having a high contact ratio of a heat transfer surface of a heating medium and an excellent heat exchange efficiency. SOLUTION: A refrigerator using a manifold with a built-in electric heating module comprises a cooling side shell 2, a heating side shell 3, a cooling side agitation member 5, a heating side agitation member 6, thermoelectric module 7, and a motor section 8. Because heat transfer surfaces 50 and 51 of the thermoelectric module 7 are disposed of in a vertical direction, air rises along the heat transfer surfaces 50 and 51 and is discharged from exhaust ports 22 and 43 provided on the upper part of a manifold 1. A permanent magnet 33 of the cooling side agitation member 5 and that of the heating side agitation member 6 are installed, so that the cooling side agitation member 5 is rotated by receiving a power transmitted from the heating side agitation member 6.

Abstract: PROBLEM TO BE SOLVED: To enhance heat transfer rate on the air side by making a slit-like cutback in the surface of fins arranged at a constant interval to pass a gas between them and arranging the cut face of the cutback in parallel with the direction of gas flow thereby accelerating the turbulence effect of the air. SOLUTION: In a heat-exchanger where a gas flowing between fins 5 arranged at a constant interval exchanges heat with a coolant flowing through a heating tube 2, a cutback 7 is made to project above the surface of the fun 5 while directing the cross-section 7' in parallel with the direction of gas flow. When heat is transmitted from the coolant circulating through the heating tube 2 through a fin collar 6 and the fin 5 to the cutback 7 and exchanged with the gas flowing between the fins 5, the gas flow collides against the end face 7" of the cutback 7 and flows to the cutback part of an adjacent cutback 7. Consequently, turbulence effect of the gas flow is accelerated and heat transfer rate is enhanced on the air side resulting in the increase of heat-exchanging amount.

Abstract: PROBLEM TO BE SOLVED: To enable prolongation of a time of a heating operation by a method wherein the height of slit-shaped cut-raised parts on the surface of a fin is made smaller toward the upstream side of a gas flow and the parts are so shaped that frost in a larger quantity can be formed on the upstream side of the gas flow than on the downstream side of the gas flow. SOLUTION: Gas is made to flow through between fins 5 disposed at uniform intervals in parallel and heat exchange is conducted between a refrigerant flowing through a copper tube 2 and the gas flow running through between the fins 5. Cut- raised parts 1 which protrude from the surface of the fin 5 on the front and the rear sides alternately and of which the height is made larger toward the downstream side of the gas flow are provided. The heat from the refrigerant circulating through the copper tube 2 is propagated to the cut-raised parts 7 through the copper tube 2, a fin collar 6 and the fin 5 and the heat exchange is conducted with the gas flow running through between the fins 5. While waterdrops are formed by condensation and turned into frost on the fins 5 and the cut-raised parts 7, a distance between the fin 5 and the cut-raised part 7 adjacent thereto is larger toward the upstream side of the gas flow, the area wherein the frost can be formed is wider toward the upstream side of the gas flow and thus a heating operation can be continued until the frost is formed uniformly on the surface of the fins 5.

Abstract: PURPOSE: To obtain a heat transfer tube using a non-azeotrope refrigerant useful recently as a substitute refrigerant which does not particularly deplete an ozonosphere in the tube used for a heat exchanger for transferring heat between the refrigerant and a fluid such as the air for an air conditioner, a refrigerator or an automobile equipment. CONSTITUTION: Many fine grooves 4 continued in parallel with a tube axial direction are provided on an inner surface, the widths of the grooves 4 are repeatedly enlarged and contracted in the continuous direction of the grooves 4, and have an uneven surface on the oblique surface 5 of the groove 4. When a non-azeotrope refrigerant is used as the refrigerant, the development of the concentration boundary layer of the refrigerant component generated on the surface of the groove 4 is scissored by the uneven surface of the oblique surface 5 and suppressed, and hence the decrease of the heat transfer rate due to the diffusion resistance can be suppressed.

When a non-azeotrope refrigerant is used as the refrigerant, the development of the concentration boundary layer of the refrigerant component generated on the surface of the groove 4 is scissored by the offset groove 4 to be able to be suppressed, and hence the decrease of the heat transfer rate due to the diffusion resistance can be suppressed.
