COMPACT HOT WATER STORAGE TANK WITH DIFFUSER AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a diffuser technology for implementing the temperature stratification in a compact or small thermal storage tank used to store hot water in the system, such as a compact cogeneration. A thermal storage tank with a diffuser may comprise: a wall plate in the form of a hollow pillar with open top and bottom, of which upper part is connected with a hot water pipe into which a hot water flows, and lower part is connected with a cold water pipe into which a cold water flows; an upper cover coupled to an upper portion of the wall plate so that the top of the wall plate is sealed; a lower cover coupled to an lower portion of the wall plate so that the bottom of the wall plate is sealed; an upper plate member wherein an upper water flow hole as a hole through which a hot water passes is comprised at the center, and one side is coupled to be spaced apart in a certain distance from the upper cover, inside the upper cover; a lower plate member wherein an lower water flow hole as a hole through which a cold water passes is comprised at the center, and one side is coupled to be spaced apart in a certain distance from the lower cover, inside the lower cover; an upper pipe guide in the form of a hollow columnar shape for passing hot water through, of which one end is connected to a hot water pipe, and the other end is connected to an upper water flow hole; and an lower pipe guide in the form of a hollow columnar shape for passing cold water through, of which one end is connected to a cold water pipe, and the other end is connected to an lower water flow hole. According to this, the temperature stratification using a diffuser in a compact or small thermal storage tank is also possible.
