AI Technical Summary

Technical Problem

The existing hot water supply methods used in hotels have problems such as small heat exchange area and uneven fluid mixing, resulting in slow heating speed and low thermal efficiency.

Method used

The system employs a square jet tube structure with the curved shape of the jet tube facing the center to increase the heat exchange area and reduce the flow dead zone. The jet holes face the center of the square, and the jet tubes are arranged in a square shape with the focal points of adjacent tube walls at the same point. Combined with the baffle design, this optimizes fluid mixing and heat exchange effects.

Benefits of technology

It improves the uniformity of fluid mixing and heat exchange efficiency, increases the mixing area and mixing time, and achieves more efficient hot water output.

Abstract

The invention provides a mixed flow heat exchange device for outputting hot water, which is characterized in that the connecting line of the vertexes of the section of a jet pipe is a square, a pipe wall is formed between the adjacent vertexes of the square, the pipe wall is bent, the bending direction of the bend faces the center of the square, and jet holes for jetting from the inside of the jet pipe to the outside of the jet pipe are formed in the pipe wall. The invention provides a heat exchange device adopting a novel square jet pipe, so that the mixing heat exchange effect of two fluids is better and more uniform, and the heat exchange efficiency is improved.
