Title:
HEAT EXCHANGER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020101329
Kind Code:
A
Abstract:
To make a discharge performance of dew condensation water better.SOLUTION: A heat exchanger is configured, so that plural tube members formed to constitute a flat heat-exchanging tube having two flow inlets/outlets of a heat-exchanging medium and a communication path communicating the two flow inlets/outlets by jointing them opposite to each other using a metal material are laminated, so that the two flow inlets/outlets of the adjacent heat-exchanging tubes are matched with each other. Heat is exchanged between the heat exchanging medium flowing in the heat-exchanging tube and a heat-exchanged medium flowing between it and the adjacent heat-exchanging tube. Plural V-like or U-like notch parts are formed on the tube member at least at one part of an outer periphery. Dew condensation water is introduced and exhausted to the notch part, so that an exhausting property of the dew condensation water can be made sufficient.SELECTED DRAWING: Figure 3
