In figure: 1 is cold flow plate, 2 is heat flux plates, and 3 is the first circulation pipe, 4 is return duct, and 5 is heat generator, and 6 is the second circulation pipe, 7 is circulating pump, and 8 is condenser, and 9 is heat exchanger, 10 is heat collector, and 11 is thermometer, and 12 is storage tank, 13 is gauge tap, and 14 is filter, and 15 is spring, 16 is valve cylinder, and 17 is spool, and 18 is relief hole
The specific embodiment
A kind of spiral heat exchanger with defencive function as shown in Figure 1, Figure 2 and Figure 3; comprise heat flux plates 2, cold flow plate 1; heat flux plates 2 is connected with cold flow plate 1 spiral winding; it is characterized in that: in described heat flux plates 2, also have relief hole 18; in relief hole 18, pressure relief device is housed; described pressure relief device is comprised of two spools 17, valve cylinder 16 and spring 15; valve cylinder 16 is contained in relief hole 18; two spools 17 are relatively positioned over valve cylinder 16Nei two ends, and two spools 17 connect by spring 15.During work, to heat flux plates 2 and cold flow plate 1 transportation of substances, conduct heat simultaneously, because the temperature of heat flux plates 2 interior materials is higher, pressure in it is also just higher, when its pressure surpasses the critical value that self structure bears, will produce blast, and machine and other people are caused to unnecessary injury.This structure by setting up 2 relief holes 18 in heat flux plates 2; the pressure relief device being comprised of two spools 17, valve cylinder 16 and spring 15 is housed in relief hole 18; when pressure is excessive; pressure can promote spring 15; gases at high pressure or liquid will be discharged from spool 17 and valve cylinder 16 space; reduce the pressure in heat flux plates 2, self structure is played a protective role.Heat flux plates 2 of the present invention and cold flow plate 1 adopted spiral winding to be connected to increase the contact area of hot and cold of heat exchanger, improved the operating efficiency of heat exchanger.
The two ends of cold flow plate 1 are as shown in Figure 1 connected with the first circulation pipe 3, the first circulation pipes 3 and are provided with condenser 8, between the outlet of cold flow plate 1 and condenser 8, are also provided with heat power collection generator.Described heat power collection generator forms by being connected in the heat collector 10 of the first circulation pipe 3, the heat exchanger 9 being connected with heat collector 10, heat generator 5 and circulating pump 7; Heat exchanger 9, heat generator 5 and circulating pump 7 are connected successively by the second circulation pipe 6.Medium in cold flow plate 1 has higher temperature after completing heat transfer, if just can not recycle to medium cooling, has greatly wasted resource.So the present invention is provided with condenser 8 on the first circulation pipe 3, this design is in order to recycle to medium cooling.If temperature wastes and can cause greatly energy waste in the medium in cold flow plate 1, so had additional heat power collection generator in the present invention between the outlet of cold flow plate 1 and condenser 8, by heat collector 10, gather the heat of medium in cold flow plate, these heats are passed to the medium of the second circulation pipe 6 by heat exchanger 9, the medium of the second circulation pipe 6 heat generator 5 of flowing through under the effect of circulating pump 7 generates electricity, finally flow back into again heat exchanger 9, complete the regeneration of the energy.
The two ends of heat flux plates 2 as shown in Figure 1 are also connected with return duct 4, and return duct 4 is provided with gauge tap 13, and gauge tap 13 is connected with storage tank 12 with thermometer 11 respectively.This design is in order to ensure needing the temperature of cooling material to meet the requirements, after temperature that thermometer 11 records material meets the demands, gauge tap 13 can be discharged into material in storage tank 12, when the temperature of material undesirable, material again flow in heat flux plates 2 by return duct 4 under the effect of gauge tap 13, carries out heat transfer again.
Filter 14 is also equipped with in the porch of heat flux plates 2 as shown in Figure 1, and described filter 14 is liquid filter or gas dust remover.This design is the impurity that is delivered into material in heat flux plates with removing, and prevents the generation that passage stops up; In the liquid that need to lower the temperature or gas, likely exist a large amount of impurity, when being deposited in a place, these impurity unifications are easy to form the obstruction of passage, not only reduced operating efficiency, and easily cause danger, so this design is very necessary, the material of not only having purified, but also played the effect that Accident prevention occurs.
In sum the present invention have simple in structure, be easy to the advantages such as manufacture, Environmental Safety, heat transfer rate be fast, there is the good market competitiveness.
