Abstract (en)
A nozzle 114a is an inlet port for a refrigerant. A recessed portion 117 (recessed area) is formed in a side plate 110a. The recessed portion 117, in conjunction with the nozzle insertion portion 131 and a bottom surface 133 of a reinforcing plate 113a, defines an inner space 119 which substantially seals the periphery of a nozzle insertion portion 131. The inner space 119 is a so-called doughnut-shaped space which surrounds the periphery of the nozzle insertion portion 131. A brazing filler material is introduced into the inner space 117 through a gap 132, and fills the inner space. As a result of the filling of the brazing filler material, the nozzle 114a, the reinforcing plate 113a, and the inner space 119 constitute a "pillar". The pillar improves the strength of the plate heat exchanger.
