- the heat exchange between the refrigerants in the adjacent regions of the portions 40 adjacent to each other in parallel can be suppressed, and the heat exchange amount between the air and the refrigerant can be increased by using the corresponding heat exchange amount.
- the performance can be improved. That is, the portions 40 of the notches 34 and 35 that are adjacent to each other in parallel function as supercooling portion heat shielding means that shields heat transfer between the adjacent transmission tubes.
- the width L2 of the portions 40 of the notches 34 and 35 adjacent to each other in parallel is not limited to the above-described 0.3 mm or more, and can be an arbitrary width.
- the heat transfer fin 31 is divided by arranging two adjacent cuts 34 and 35 arranged substantially in parallel with the interval L2 being 0.3 mm or more on the same plane of the heat transfer fin 31. Instead, they are connected. Therefore, the heat transfer fin 31 can be stably mass-produced without being sprinkled in the mass-production molding process, without being caught by a press machine and clogging.
- the heat transfer fin 31 is divided by arranging two adjacent cuts 34 and 35 arranged substantially in parallel with the interval L2 being 0.3 mm or more on the same plane of the heat transfer fin 31. Instead, they are connected. Therefore, it is possible to prevent the worker in the mass production process of the heat transfer fin 31 from being wound at the turned-up portion without being flipped up in the mass production molding process of the heat transfer fin 31.
- the heat exchanger for an air conditioner according to the present invention has an effect of increasing the amount of heat exchange between the air and the refrigerant by making a notch having an arbitrary width on the heat exchanger fins. Therefore, it is also useful for applications such as heat dissipation heat exchangers used in electronic devices.
