Description
Technical field
The present invention relates to heat exchange field, relate in particular to a kind of heat-exchange system.
Background technology
Conventionally utilize existing cooling water and circulation of fluid to carry out heat exchange with the temperature of controlled circulation fluid, can utilize afterwards described circulation of fluid to go to control the temperature of other objects or equipment.Described cooling water is generally the cooling water that shop equipment is made of product water or cooling tower, and this cooling water temperature is (for example 20 degree Celsius) fixed mostly.Described object or equipment often need a certain temperature or a variable temperature range, and for example certain temperature in-20 degree ~ 80 degree Celsius, therefore generally carries out temperature control by described circulation of fluid to described object or equipment.
This heat exchange can regulate hot exchange power by controlling the flow of cooling water, when the temperature of circulation of fluid approaches the temperature of cooling water, because temperature difference is little, reaching certain hot exchange power needs the flow of cooling water larger, when the temperature of circulation of fluid is much higher than the temperature of cooling water, because temperature difference is large, reach certain hot exchange power needs the flow of cooling water less.
The Flow-rate adjustment of described cooling water is used manually-operated gate or straight line electric valve conventionally, the shortcoming of manually-operated gate is to need the artificial temperature for different circulation of fluids to regulate different cooling water flows, and straight line electric valve is difficult to cooling water to carry out little water yield adjusting.
Summary of the invention
For problems of the prior art, the present invention proposes a kind of heat-exchange system, the flow of the temperature fine adjustment cooling fluid that it can be based on 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 described cooling fluid pipeline through cooling fluid entrance, flows into afterwards described heat exchanger, again flows into described cooling fluid pipeline subsequently, finally by being flowed out by cooling fluid pipe outlet by described heat exchanger; Circulation of fluid enters described circulation of fluid pipeline through circulation of fluid pipeline inlet streams, flows into afterwards described heat exchanger, again flows into described circulation of fluid pipeline subsequently, finally by being flowed out by circulation of fluid pipe outlet by described heat exchanger.Described heat-exchange system also comprises the temperature sensor for detection of described circulation of fluid temperature on the path that is arranged at described circulation of fluid and is arranged at the electromagentic switching apparatus that the circulation of fluid temperature detecting based on described temperature sensor on the path of circulation of fluid is controlled the flow of described cooling fluid.
Compared with prior art, in the present invention, be provided with the electromagentic switching apparatus that the circulation of fluid temperature detecting based on described temperature sensor is controlled the flow of described cooling fluid, realized so the automatic accurate control of the flow of cooling fluid.
