ことにより、凝縮器の板状フィン部分まで落下した除霜
水の氷結を防止することができるので、熱伝達効率の向
上を図ることができる。As described above, according to the heat exchanger of the present invention, a plurality of parallel communication pipes are provided between a pair of defrosting header pipes facing the lower end of the header pipe of the evaporator. Along with the connection, a plurality of plate-like fins are arranged in a direction orthogonal to these communication tubes, and while the heat medium flows into the header pipe for defrosting and flows through the communication tubes, the plate-like shape of the condenser is formed. Since deicing water that has fallen to the fin portion can be prevented from freezing, heat transfer efficiency can be improved.
