<p>The invention provides an evaporator 1 comprising an evaporator core 2 having a refrigerant inlet 2A and a refrigerant outlet 2B in one side portion thereof, and a connecting member 3 joined to the side portion of the core 2 and having in its interior a refrigerant inlet channel 3A and a refrigerant outlet channel 3B. The connecting member 3 comprises a first plate 31 and a second plate 32. The second plate 32 has an inlet channel recessed portion 32A and an outlet channel recessed portion 32B, which are provided, each in the bottom wall thereof, with an inlet pipe connecting opening 321 and an outlet pipe connecting opening 322, respectively. The first plate 31 is provided on the outer surface thereof with a refrigerant flow smoothing projection 310A projecting toward the inlet pipe connecting opening 321. The refrigerant flowing into the inlet channel 3A flows along the surface of the projection 310A, thereby changes the direction of its flow smoothly and is less likely to produce a turbulent flow. The evaporator 1 is therefore adapted to prevent occurrence of noises due to the flow of refrigerant.</p> |
