Fig. 2 is the utility model economic benefits and social benefits cooler A-A cross section upward view.

Reference numeral among the figure is: 1 urceolus; 2 inner cores; 3 double helix coil pipes; 4 secondary cooling chambers; 5 bolts; 6 outer drum flanges; 7 end cap flanges; 8 sample water outlets; 9 coolant outlets; 10 precooling chambeies; 11 cooling water inlets; 12 sealing gaskets; 13 sample water inlets.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:

Among Fig. 1, the economic benefits and social benefits cooler comprises the urceolus 1 with blind end and openend, and the outer rim of its openend is provided with outer drum flange 6, and end cap flange 7 is fixedly connected with outer drum flange 6 by bolt 5; Establish cooling water inlet 11 on the wall of urceolus 1, establish coolant outlet 9, sample water outlet 8 and sample water inlet 13 on the end cap flange 7, sample water outlet 8 and sample water inlet 13 are connected to respectively the two ends of double helix coil pipe 3.

The inside of described urceolus 1 is provided with inner core 2, and an end of inner core 2 does not contact with the inwall of urceolus 1 blind end, and the other end of inner core 2 is fixed on the end cap flange 7, and inner core 2 is the concentric circles welding with the connected mode of end cap flange 7.
