Tube-plate heat exchanging apparatus and seawater desalting system thereof

Abstract

The invention provides a tube-plate heat exchanging apparatus and a seawater desalting system thereof. The tube-plate heat exchanging apparatus comprises an inlet header, an outlet header, an inlet heat exchanging tube, an outlet heat exchanging tube and plate groups, wherein the inlet header is connected with the inlet heat exchanging tube, the inlet heat exchanging tube is connected with the corresponding plate group, the plate group is a heat exchanging passage formed by combining two plates, the plate group is connected with the outlet heat exchanging tube, the outlet heat exchanging tubeis connected with an outlet collecting box, and fluid from an evaporation end enters the inlet heat exchanging tube by virtue of the inlet header, then enters the plate group by virtue of the inlet heat exchanging tube, enters the outlet heat exchanging tube by virtue of the plate group and is finally discharged by virtue of the outlet header. The invention provides a novel tube-plate heat exchanging structure; and by virtue of the tube-plate combination, the resistance can be further reduced, the heat dissipation area can be enlarged, and the heat dissipation efficiency can be improved. By virtue of a heat exchanger playing a role in desalting and spraying the seawater, the seawater desalting effect can be improved.

Description

technical field [0001] The invention relates to the fields of loop heat pipes, solar energy and seawater desalination, in particular to a loop heat pipe utilizing solar energy and a seawater desalination system thereof. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air vo...

Problems solved by technology

[0004] There are more than 10,000 islands in China, but most of them are uninhabitable due to lack of fresh water, and there are less than 500 permanent residents, which restricts the functions of island development and national defense.
