Abstract: PURPOSE:To make a thin interface layer generated on the surface of the fins to get a higher thermal transfer by a method wherein fins having gate-shaped cut and raised slotted pieces formed by bending the front edges at the gas flow inlet end and the thermal medium pipe passing through the fins are provided. CONSTITUTION:A heat exchanging operation is performed between a gas flow B and a thermal medium flowing in the thermal medium pipe 2. The gas flow B flowing along the surfaces of the small piece fins 3 is abutted against the gate-shaped cut and raised slotted pieces 4 at the front edges of the fins to increase a distribution of pressure, so that the higher thermal conduction is increased between the surfaces of the cut and raised slotted pieces 4 and the gas flow B. Further, the gas flow B abutted against the cut and raised slotted pieces 4 is passed through the area enclosed by the pieces 4 and the fins 3, so that the flow speed of the gas is accelerated, the interface layer generated at the surfaces of the fins 3 becomes thin. When the gas flow B is struck against the pieces 4, the gas flow B generates eddy current at the pieces 4 to promote the disturbance and the interface layer generated at the surfaces of the fins 3 becomes more thin and thereby a higher thermal transfer is provided between the fins 3 and the gas flow B. Further, since the fins 3 are divided into each of the rows in a direction of the gas flow B, the development of the interface layer is interrupted and the performance of the thermal transfer is further promoted.

Abstract: PROBLEM TO BE SOLVED: To provide a manifold incorporating a thermoelectric module in which heat exchanging efficiency is enhanced by regulating the flow rate of heat carrier. SOLUTION: In a manifold 1 incorporating a thermoelectric module 7, heat exchanging efficiency is enhanced by differentiating the flow rate of heat carrier on the cooling side from the flow rate of heat carrier on the heating side. In order to lower the temperature of heat carrier on the cooling side, channel resistance in the manifold 1 is designed such that the flow rate of heat carrier on the heating side is lower than the flow rate of heat carrier on the cooling side. When pump components, e.g. impellers 5, 6 constituting a volute pump, are incorporated, heat carrier delivery capacity of the pump components is designed.

Abstract: PROBLEM TO BE SOLVED: To provide a cooler utilizing Peltier effect which can operate with no trouble even under inclining state, and a method for increasing the chance of contact between a heat carrier and the heat transfer surface of a thermoelectric module by removing bubbles in the piping. SOLUTION: In an air purge chamber, pipes (tubular members) are employed at both the heat carrier inlet 48 and heat carrier outlet 49 extending into a container 47. The pipes enter the container 47 from the center on the bottom face thereof. The pipe constituting the heat carrier inlet 48 extends to the vicinity of the center of gravity of the container 47 and opens thereat.

Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the pressure loss while maintaining conventional heat transfer by forming oblique grooves having reverse angle to a tube axis and linear grooves parallel to the axis via the intersection of the grooves gathered reversely to the flow of refrigerant in the shape divided by specific even number at the circumference of the tube on the inner surface. SOLUTION: Oblique grooves 6 having reverse angle to a tube axis are formed and linear grooves 7 parallel to the axis via the intersection of the grooves 6 gathered reversely to the flow of refrigerant are formed in the shape divided by even number of 4 or more at the circumference of the tube on the inner surface. The vapor refrigerant flowing in a horizontal condensing heat transfer tube 5 is condensed, the condensed refrigerant flows along the grooves 6, gathered at the grooves 7 parallel to the axis and fed. Thus, the liquid refrigerant to be thermal resistance in the groove 5 is excluded, and the effective transfer area in which the tube 5 is in contact with the vapor refrigerant effective to the heat transfer is increased. Therefore, the transfer of the tube 5 to the refrigerant is expedited, and the pressure loss can be reduced.
