Document Type and Number:
WIPO Patent Application WO/2019/135292
Kind Code:
A1
Abstract:
[Problem] To improve the operating efficiency of a heat pump. [Solution] The liquefaction promoting device having springs capable of oscillating and rocking is provided with: a housing in which the upper end and lower end of a cylindrical body section are closed respectively by hemispherical end plates; an upper tube body which, at a position separated from a center axis, extends vertically through the upper end plate up to the vicinity of the upper end of the body section, and which has the other end open downward; a lower tube body which extends vertically along the center axis through the lower end plate up to the vicinity of the upper end of the body section, and which has the other end open upward; a large-diameter helical spring mounted within the body section about the center axis with the upper end and lower end of the helical spring affixed, each of the windings of the intermediate section of the helical spring being capable of rocking and oscillating, the helical spring having a diameter smaller by 1 to 10 mm than the inner diameter of the body section; and a small-diameter helical spring mounted around the lower tube body with the upper end of the helical spring affixed to the upper end of the lower tube body and with the lower end extending up to the vicinity of the lower end plate, each of the windings being capable of rocking and oscillating without coming into contact with the large-diameter helical spring, the helical spring having a diameter greater by 1 to 30 mm than the contour of the lower tube body.
