EVAPORATOR

PROBLEM TO BE SOLVED: To provide an evaporator that can remarkably increase heat exchange efficiency by distributing a liquid phase and gas phase of a refrigerant substantially evenly to a plurality of tubes. SOLUTION: The evaporator 100 comprises the plurality of stacked tubes 101, an inlet tank 103 in communication with ends of them on one side, an outlet tank 104 in communication with the other ends, a refrigerant inlet pipe 105 connected to the inlet tank 103 to supply a refrigerant, and a refrigerant outlet pipe 106 connected to the outlet tank 104 to discharge out the refrigerant past the tubes 101; and positions the inlet tank 103 under the tubes 101. The inlet tank 103 comprises a flat tank part 103b and a side tank part 103a formed in a larger height dimension perpendicular to a refrigerant flow than the flat tank part 103b. The refrigerant inlet pipe 105 and the tubes 101 are connected to the side tank part 103a and the flat tank part 103b respectively. COPYRIGHT: (C)2006,JPO&NCIPI
