摘要： A heat exchanger for use as an evaporator, for example, in refrigerators wherein a hydrocarbon refrigerant is used. The heat exchanger comprises a finned zigzag tube 1 comprising a zigzag tube member 2 formed by bending a pipe having no welded seams, the zigzag tube member 2 having at least three straight tube portions 2a arranged from the front rearward at a spacing and parallel to one another, a plurality of first fin groups 3 arranged at a spacing on two adjacent straight tube portions 2a of the zigzag tube member 2 longitudinally of the straight tube portions and each comprising plate fins 5 extending across and fixedly arranged in parallel on the adjacent straight tube portions 2a, and a plurality of second fin groups 4 each comprising plate fins 6 fixedly arranged in parallel on each remaining straight tube portion 2a of the zigzag tube member 2, the second fin groups 4 being arranged at a spacing on the remaining straight tube portion 2a longitudinally thereof so as to be in the same positions as the respective first fin groups 3 with respect to the longitudinally direction of the straight tube portions 2a. The heat exchanger E comprising the finned zigzag tube 1 exhibits the desired refrigeration performance with the leakage of refrigerant diminished.

摘要： A heat exchanger finned tube 10 for use in fabricating a heat exchanger 1 useful as the evaporator for refrigerators or the like wherein a hydrocarbon refrigerant is used. Two tube insertion holes spaced apart from each other are formed in each of plate fins 12, and two straight tube portions 11a of a hairpin tube 11 are inserted through the respective holes of each plate fin to arrange the plate fins 12 in parallel into a plurality of fin groups 13 spaced apart on the straight tube portions 11a longitudinally thereof. The hairpin tube 11 is enlarged with use of a fluid to fixedly fit the plate fins 12 of each tin group 13 around an enlarged tube portion 14 of the hairpin tube 11 and provide a finless part 19 between each pair of adjacent fin groups 13 on each of the straight tube portions 11a. A restrained small-diameter portion 15 is provided in each of the finless parts 19 of each straight tube portion 11a. The heat exchanger 1 fabricated using the finned tube 10 exhibits the desired refrigeration performance with the leakage of refrigerant diminished.

摘要： A heat sink has a panel body and a heat radiating portion. The panel body includes a working fluid circuit for circulating a working fluid in the panel body and has a heat receiving portion and a heat radiating portion substantially on the same plane. The heat radiating portion has an upper region and a lower region. The heat receiving portion is provided on a lateral side of the lower region of the heat radiating portion, and a plurality of radiating fins are provided on at least one surface of the heat radiating portion of the panel body. The working fluid circuit extends from the heat receiving portion to the lower region of the heat radiating portion and further to the upper region of the heat radiating portion, and the working fluid circuit in the lower region of the heat radiating portion has an average channel cross sectional area which is smaller than an average channel cross sectional area of the working fluid circuit in the heat receiving portion.
