Title:
流下液膜式蒸発器
Document Type and Number:
Japanese Patent JP5850099
Kind Code:
B2
Abstract:
The present invention provides a falling film evaporator in which the flow rate of refrigerant in the vicinity of a vapor outlet tube can be suppressed to be low. A falling film evaporator (1) in which liquid refrigerant, within gas/liquid two-phase refrigerant supplied into a tank (10), is dropped through a two-stage refrigerant tub (35) onto a heat transfer tube bundle (20). An upper cover (36) is provided above the two-stage refrigerant tub (35) inside the tank (10). A perpendicular plate (40) is provided between the two-stage refrigerant tub (35) and the upper cover (36), in a different position from a vapor outlet tube (18) with respect to the longitudinal direction of heat transfer tubes (21), and the perpendicular plate impedes the flow of refrigerant flowing between the two-stage refrigerant tub (35) and the upper cover (36) and flowing in the longitudinal direction of the heat transfer tubes (21).
