Title:
HEAT EXCHANGER AND AIR CONDITIONER USING THAT HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2022040969
Kind Code:
A
Abstract:
To provide a heat exchanger in which a heat transfer tube in a flat shape passes through a plurality of fins, where the heat exchanger secures a drainage performance of condensed water retained on a surface of the heat transfer tube while improving a heat transfer rate, and further suppresses increase in ventilation resistance.SOLUTION: A heat exchanger 100 comprises a heat transfer tube 1 in a flat shape and a plurality of fins 2 provided to the heat transfer tube 1, where a refrigerant flowing inside the heat transfer tube 1 exchanges heat with air flowing between the plurality of fins 2. Each fin 2 comprises: a heat transfer expansion surface 21 comprising a peak portion 21x and a valley portion 21y provided along an air flow direction; and a drain structure 22 provided to overlap the heat transfer expansion surface 21.SELECTED DRAWING: Figure 3
