Detailed Description
The present invention and the effects thereof will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a single-side self-circulation cooling system includes a hot fluid inlet 1, a hot fluid inlet valve 2, a heat exchanger 3, a hot fluid outlet 18, a hot fluid outlet valve 17, a cold fluid inlet 15, a cold fluid return inlet 14, a cold fluid return valve 16, a cold fluid inlet valve 19, a cold fluid outlet 6, a cold fluid outlet valve 4, a cold fluid outlet pressure gauge 5, a cold fluid outlet thermometer 7, a cold fluid level gauge 13, an air cooler 9, an air cooler inlet 8, an air cooler outlet 11, a fan motor 10, and an air cooler outlet thermometer 12.
The air cooler 9 is higher than the heat exchanger 3 in the parts, so that cold flow is driven by the driving force provided by the height difference between the heat exchanger and the air cooler, the pressure head loss in the system is overcome, and self-circulation heat exchange is carried out in the heat exchange system.
The hot fluid of the heat exchange system firstly flows in from a hot fluid inlet 1, flows in a heat exchanger 3 through a hot fluid inlet valve 2, exchanges heat with cold fluid in the heat exchanger 3, then flows out from a hot fluid outlet valve 17, and finally flows out from a hot fluid outlet 18. The heat flow inlet 1, the heat flow inlet valve 2, the heat exchanger 3, the heat flow outlet valve 17 and the heat flow outlet 18 are communicated in sequence.
The cold flow of the heat exchange system firstly flows in from the cold flow inlet 15, enters the heat exchanger 3 through the cold flow inlet valve 19, exchanges heat with the hot flow in the heat exchanger 3, then flows out from the cold flow outlet 6 through the cold flow outlet valve 4, and finally enters the air cooler through the air cooler inlet 8. The cold flow completes heat exchange in the heat exchanger 3, the temperature and the pressure of the cold flow can be observed and recorded through a cold flow outlet pressure gauge 5 and a cold flow outlet thermometer 7 which are arranged on a pipeline at a cold flow outlet 6, and the system stability is guaranteed. The cold flow inlet 15, the cold flow inlet valve 19, the heat exchanger 3, the cold flow outlet valve 4 and the cold flow outlet 6 are communicated with each other in sequence.
The cold fluid level meter 13 is arranged in the heat exchanger 3, and the cold fluid level in the heat exchanger shell can be observed through the cold fluid level meter 13. The cold and hot fluid inlet and outlet valves can adjust the cold fluid liquid level in the shell to be at a proper position.
The cold flow of the heat exchange system flows into the air cooler 9 from the air cooler inlet 8, flows out from the air cooler outlet 11 after being cooled, and finally returns to the heat exchanger 3 again through the cold flow reflux inlet 14 and the cold flow reflux valve 16. The air cooler inlet 8 and the air cooler outlet 11 are connected with the air cooler 9. And the cold flow reflux inlet 14 and the cold flow reflux valve 16 are communicated with the heat exchanger 3 in sequence.
The air cooler fan motor 10 is interlocked with the air cooler outlet thermometer 12, and the cold flow outlet temperature of the air cooler can be controlled by adjusting the frequency of the fan motor. The fan can be increased by increasing the motor frequency of the fan
The air quantity is reduced, so that the temperature of a cold flow outlet of the air cooler is reduced, cold flow flows back into the heat exchanger again after flowing out of the air cooler, the heat transfer temperature difference between the cold flow outlet and the hot flow outlet is increased, and the heat exchange efficiency of the heat exchanger is improved. Thereby realizing the accurate control of the heat exchange efficiency of the heat exchange system.
The heat exchanger 3 is provided with a hot fluid flowing tube side and a cold fluid flowing shell side.
