AI Technical Summary

⚠Technical Problem

Traditional shell-and-tube heat exchangers have low heat transfer efficiency, and existing methods to enhance heat transfer are not ideal and cannot effectively improve the heat transfer effect.

⚗Method used

It adopts a rhomboid heat exchange tube structure, with upper and lower chambers, evaporation tubes and condenser tubes inside. The liquid evaporates rapidly in the upper chamber and returns to the lower chamber through the condenser tube, realizing rapid heat exchange between the inside and the cold source, and heat exchange between the outside and the heat source. Combined with the horizontal shell-and-tube heat exchanger and baffle design, the fluid flow is optimized to increase the heat exchange area and uniformity.

🎯Benefits of technology

It significantly improves the heat exchange efficiency of the heat exchanger, increases the heat source distribution range and the heat exchange area of ​​the cold source, and achieves a more uniform heat distribution and a higher heat transfer effect.

Abstract

The application provides a rhombic heat pipe type heat exchange pipe, a closed vacuum space is formed between an upper cavity, a lower cavity, an evaporation pipe and a condensation pipe, and the lower cavity is filled with liquid; a condenser is arranged at the lower part of the heat exchange pipe, which is used for concentrating sunlight to the lower part of the lower cavity, and is used for heating the liquid in the lower cavity; the liquid is evaporated along the evaporation pipe after absorbing heat, enters the upper cavity, and then returns to the lower cavity along the condensation pipe; at least one part of the evaporation pipe, the condensation pipe and the upper cavity exchanges heat with a cold source in the heat exchange pipe. The structure of the heat exchanger is improved, the liquid in the cavity is quickly evaporated by arranging the upper and lower cavities and the evaporation pipe and the condensation pipe, so that the steam fills the whole evaporation pipe and the condensation pipe, fills the whole heat exchange pipe, quickly heats the cold source in the base pipe, and the heat exchange speed is greatly improved.
