PROBLEM TO BE SOLVED: To provide a flat plate vaporizer. SOLUTION: The flat plate vaporizer has such a structure as the common chamber of a substrate having specified diameter and depth for containing refrigerant is sectioned into a vaporization cavity region, a capillary tube region surrounding the vaporization cavity region, and a manifold region surrounding the capillary tube region, a wick structure is formed in the capillary tube region, and an exhaust means including a section for exhausting vapor phase refrigerant produced in the vaporization cavity region to the outside is provided on an upper plate. A small and thin cooler which can be cooled without requiring any external power can be obtained using that evaporator. Since liquid state refrigerant can be isolated from evaporated gas phase refrigerant by the capillary tube region, lowering in the fluidity of fluid due to mixture of gas and liquid can be suppressed efficiently and heat exchanging characteristics can be enhanced significantly. |
