Abstract:
1. An evaporator, comprising: a plurality of tubes stacked in regularly spaced relation to one another and configured to have coolant flowing therethrough, each of said tubes being formed by two coupled tube plates; fins interposed between the tubes; a tank joined to and configured to be in fluid communication with the plurality of tubes at an upper or lower side of the plurality of tubes; an inlet end-plate and an outlet end-plate which respectively have an inflow part and an outflow part at an upstream side of coolant flow and which are positioned at respective end sides of the stacked tubes; and an inlet manifold and an outlet manifold which are joined to and configured to be in fluid communication with the tank and also coupled to the inflow part and the outflow part so as to define a coolant flow passage, wherein the outlet manifold has a coolant movement preventing part which isolates a rear portion of the outlet manifold from the coolant flow passage and comprises a closed space formed by joining the outlet end-plate and the outlet manifold to prevent formation of a dead zone in which the coolant from the tank, joined to and in fluid communication with an adjacent tube, flows into a downstream side of the outlet manifold and is whirled therein.
