A kind of novel injection water cooling system, including double pipe heat exchanger, the first water supply line, the second water supply line and
Electric-heating belt, it is characterised in that: described sleeve pipe formula heat exchanger includes inner tube and at least one layer of outer tube, first water supplying pipe
The front end of main pipeline is arranged in road, and the rear end of main pipeline, first water supply line and is arranged in second water supply line
Two water supply lines are connected by described sleeve pipe formula heat exchanger inner tube, and the electric-heating belt is set to the outer of the first water supply line
Layer, to guarantee that the temperature of the first water supply line is higher than 70 DEG C.
Further, first water supply line lower end and the junction of described sleeve pipe formula heat exchanger inner tube setting first
Flow control valve.
Further, water nozzle is arranged in described sleeve pipe formula heat exchanger internal layer pipe end, and second flow control is arranged at water nozzle
Valve processed.
Further, cooling water intake is arranged in described sleeve pipe formula heat exchanger outer tube one end, and is provided with third flow
Control valve, cooling water outlet is arranged in the other end, and is provided with the 4th flow control valve.
It further, further include temperature sensor and controller.
Further, the temperature sensor is set to the front end of the water nozzle, and described controller one end and temperature pass
Sensor connection, the other end are connect with third flow control valve and the 4th flow control valve respectively, and third stream is controlled according to temperature
The opening degree of control valve and the 4th flow control valve.
Further, insulating layer is arranged in the electric-heating belt outer layer, reduces heat loss.
The utility model has the advantage that
The utility model is passed through circulating water by the outer layer of double pipe heat exchanger to cool down, so that water for injection temperature drops
Low, when temperature is lower than 40 DEG C, water nozzle valve is opened, and facilitates personnel's water；When with water, electric-heating belt can make immobilising first
Water for injection temperature in water supply line remains at 70 DEG C or more, to reach State Food and Drug Administration's promulgation
The requirement of GMP.
