Abstract: A manifold incorporating a thermoelectric module having a wide contact of a heat medium with a heat transfer surface of the thermoelectric module and an excellent heat exchange efficiency, and a circular thermoelectric module easily manufactured and constructed into a multi-stacked structure. The manifold (1) comprises a cooling-side manifold piece (2), a heating-side manifold piece (3), a cooling-side agitating member (5), a heating-side agitating member (6), a thermoelectric module (7) and a motor member (8). Heat transfer surfaces (50, 51) of the thermoelectric module (7) are disposed vertically, so that if air enters the cavities (52, 55), air rises along the heat transfer surfaces (50, 51) and exhausted from the exhaust ports (22, 43) at the top of the manifold (1). The cooling-side agitating member (5) and the heating-side agitating member (6) are provided with permanent magnets (33), so that the cooling-side agitating member (5) receives a driving force from the heating-side agitating member (6) and is rotated. A square thermoelectric module (11) is held between aluminum disks (12, 13) to form a circular thermoelectric module (10).

Abstract: A thermoelectric module (7) having a heat absorbing surface and a heat radiating surface designed so that the heat radiating surface is heated and the heat absorbing surface is cooled by having an electric current passed therethrough is built in a manifold main body (17), while fluid-receiving cavities (10c, 10d, 20d) are formed between it and at least either the heat absorbing surface or the heat radiating surface, and hollows (10a, 10b, 20a, 20b) extending from outside to the cavities (10c, 10d, 20d) are formed. Further, installed in the manifold main body (17) are a stirring member for stirring the fluid in the cavities that has a stirring portion (15) integrated with a rotor (16), and a stator (8) fitted on the manifold main body (17), the rotor (16) and stator (8) constituting a motor. In this arrangement, an electric current is passed through the stator (8) to rotate the stirring member (5) in the cavities, causing the fluid to pass through the rotor (16) to reach the cavities (10c, 10d).

Abstract: In a thermoelectric device, such as a thermoelectric manifold, having a plurality of stages of thermoelectric modules, it is intended to improve heat exchange efficiency by uniformizing heat distributions on a heat absorbing surface and a heat radiating surface and to suppress thermal strain in the thermoelectric modules and ensure good heat transmission between the thermoelectric modules even if they are curved. To this end, in a thermoelectric device provided with a plurality of thermoelectric modules, fluid serving as heat medium is interposed between the thermoelectric modules and heat transmission through this fluid is effected from the heat radiating surfaces of the thermoelectric modules on the cooling side to the heat absorbing surfaces of the thermoelectric modules on the heating side.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of heat exchanging amount and restrain frosting at the upstream of air stream to elongate the period of time of heating operation by a method wherein continuous draining groove is provided in the direction of gravity between mutual rows of heat transfer tubes on a fin. SOLUTION: Heat exchange is effected between air flow, which flows between fins 4, and refrigerant, which flows through the inside of a heat transfer tube 2, through the fin 4 and the heat transfer tube 2. In this case, when the evaporating temperature of the refrigerant is lowered, moisture in air is condensed on the surface of the fin 4a at the upstream side of the air flow. The condensate is conducted by the air flow to flow along the fin 4a toward the downstream of the air flow and flows into a draining groove 5, continued in the direction of gravity between mutual rows of the heat transfer tubes 2 on the fin 4, then, is discharged into the direction of gravity. Accordingly, the inflow of the condensate, condensed on the fin 4a at the upstream of the air flow and precluding the heat exchange between the air flow and the fin 4, into a fin 4b at the downstream side of the air flow is prevented whereby the deterioration of heat exchanging amount between the fin 4b at the downstream side of the air flow and the air flow can be prevented.

Abstract: PROBLEM TO BE SOLVED: To promote heat transfer between a fin and an air flow and restrict a rapid reduction of heat exchange quantity during frosted state by a method wherein a plurality of continuous slits and a flat surface having no slit are alternatively arranged in a direction of stage perpendicular to an air flow between the heat transfer pipes at the surfaces of the fins of the most-forward rows in respect to a direction of air flow. SOLUTION: A heat exchanger having fins is comprised of fins 4 arranged in a specified spaced-apart relation in parallel from each other where gas is flowed between them, and a plurality of heat transfer pipes 2 passing through the fins 4 and having fluid flowed therein. Then, a plurality of continuous slits 5 and a flat surface 6 having no slit 5 are alternatively arranged in a step direction perpendicular to an air flow between the heat transfer pipes 2 at the surfaces of the fins 4 positioned at the most- forward row in respect to a direction of air flow. Even if the slits at the forward row showing a high heat exchange quantity are closed by frosting, since the air flows at the flat surfaces alternatively arranged in every stages of the front row, it is possible to delay a closing of the flow passage in an entire front row in the heat exchanger and to restrict a rapid reduction of a heat exchange quantity caused by a reduction in an air amount.

Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in a heating capacity due to frost generated on heat exchanger fins for an outdoor unit at the time of a heating operation in a finned heat exchanger used for a air conditioner or a refrigerator to deliver and receive heat between a refrigerant and a fluid such as the air. SOLUTION: Louvered parts 7 protruding from a surface of a fin 5 are formed lower in height toward a downstream side of an air flow and are inclined so that the downstream side of the air flow of the parts 7 are formed lower than an upstream side of the air flow of the parts 7. Thus, water content condensed at the parts 7 is easily drained from the parts 7 via the air flow. Drain grooves 8 are provided on the film at lower rear parts of the parts 7 at the downstream side of the air flow so that the water content drained from the parts 7 easily flows down to suppress formation of frost on the fin.

Abstract: PROBLEM TO BE SOLVED: To make it possible to expedite heat transfer and to reduce pressure loss by forming a linear grove parallel to the tube axis via an intersection of the oblique groove having a reverse angle to the axis and the oblique groove gathered in the reverse direction to the flow of refrigerant in the shape of dividing the circumference of the tube by specific even number on the inner surface. SOLUTION: Oblique grooves 6 having a reverse angle to a tube axis is formed, and a linear groove 7 parallel to the axis is formed via the intersection of the oblique grooves 6 gathered in the reverse direction to the flow of refrigerant in the shape divided by even number of 4 or more on the circumference of the tube on the inner surface. Liquid refrigerant flowing in a horizontal boiling heat transfer tube 5 flows to the grooves 7, each suitable amount of liquid refrigerant is suppled to the groove 6 by the shearing force of gas and liquid interface, the effective heat transfer area in contact with the refrigerant effective to the heat transfer to the tube 5 is increased, and a thin liquid film is formed in the grooves 6. Thus, the transfer of the tube 5 to the refrigerant is expedited, and the pressure loss can be reduced.
