PLATE-TYPE HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/076751
Kind Code:
A1
Abstract:
A plate-type heat exchanger for which the plate thickness t of heat transfer plates (2, 3) is 0.2 mm or less, the pitch Λ of concavities and convexities (9, 10) is 4-7 mm, the distance h between the apexes of the concavities and convexities (9, 10) is 1.0-1.2 mm, and the area enlargement ratio Φ, defined as the value when the wavelength s corresponding to the length of the heat transfer plates (2, 3) between the apexes of the waves of the concavities and convexities (9, 10) of the heat transfer plates (2, 3) is divided by the pitch Λ of the concavities and convexities (9, 10), is 1.05-1.15.
