This heat exchange can be regulated hot exchange power through the flow of control cooling water; In the temperature of circulation of fluid during near the temperature of cooling water; Because temperature difference is little, reach certain hot exchange power needs the flow of cooling water bigger, when the temperature of circulation of fluid is much higher than the temperature of cooling water; Because temperature difference is big, reach certain hot exchange power needs the flow of cooling water less.
The Flow-rate adjustment of said cooling water is used manually-operated gate or straight line electric valve usually; The shortcoming of manually-operated gate is to need the artificial different cooling water flow of adjustment to different circulation of fluids, and the straight line electric valve is difficult to cooling water is carried out little water yield adjusting.
Summary of the invention
To the problem that exists in the prior art, the present invention proposes a kind of heat-exchange system, and it can accurately regulate the flow of cooling fluid based on the temperature of circulation of fluid.
According to an aspect of the present invention, the present invention proposes a kind of heat-exchange system, and it comprises: circulation of fluid pipeline, cooling fluid pipeline and heat exchanger.Cooling fluid flows into said cooling fluid pipeline through the cooling fluid entrance, flows into said heat exchanger afterwards, flows into said cooling fluid pipeline once more by said heat exchanger subsequently, flows out via the cooling fluid pipe outlet at last; Circulation of fluid flows into said circulation of fluid pipeline through circulation of fluid pipeline inlet, flows into said heat exchanger afterwards, flows into said circulation of fluid pipeline once more by said heat exchanger subsequently, flows out via the circulation of fluid pipe outlet at last.Said heat-exchange system comprises also that being used on the path that is arranged at said circulation of fluid detected the temperature sensor of said circulation of fluid temperature and be arranged at and controls the electromagentic switching apparatus of the flow of said cooling fluid based on the detected circulation of fluid temperature of said temperature sensor on the path of circulation of fluid.
Compared with prior art, be provided with the electromagentic switching apparatus of controlling the flow of said cooling fluid based on the detected circulation of fluid temperature of said temperature sensor among the present invention, realized the automatic accurate control of the flow of cooling fluid like this.
