Title:
PLATE-SHAPED HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/098668
Kind Code:
A1
Abstract:
The present invention has a simple configuration, captures sludge included in a refrigerant and suppresses the risk of refrigerant circuits clogging. A plate-shaped heat exchanger 2 is provided with a plate laminated body 20, layered with a plurality of heat transfer plates 220, 230, in which a heat medium inflow port 243, a heat medium outflow port 244, a refrigerant inflow port 241 and a refrigerant outflow unit 242 that outflows a refrigerant and is provided below the refrigerant inflow port are formed, and is formed by alternating, between neighboring heat transfer plates, a heat medium flow channel 209 that flows a heat medium flowing in from the heat medium inflow port and a refrigerant flow channel 206 that flows the refrigerant flowed in from the refrigerant inflow port downwards; and a refrigerant outflow nozzle 205 that outflows the refrigerant outflowing from the refrigerant outflow unit outside the plate laminated body, provided to the plate laminated body protruding in the lamination direction of the plurality of heat transfer plates, and a protrusion 215 is formed protruding upwards on an internal peripheral surface of the refrigerant outflow nozzle.
