Described flexible inner bag is silica gel sheath, is provided with container cavity in the silica gel sheath.
The beneficial effects of the utility model are as follows.
(1) this kind of heat-generating pipe syndeton is utilized the material behavior of flexible inner bag, by being compressed, ring flange and flexible inner bag can realize sealing, simultaneously, too compressed for fear of the heat-generating pipe putting hole edge of flexible inner bag and to be caused breakage, so be provided with limited block in the ring flange outside, when pressing plate contacted with limited block, distance can not recompress between ring flange and the pressing plate during connection, thereby guaranteed to be pressed on the decrement of the flexible liner material between pressing plate and the ring flange;
(2) can be by in conjunction with factors such as the manufactured materials of flexible inner bag, material thickness, working environments, draw heat-generating pipe putting hole edge and under the situation of that decrement, be in best life-span and sealing effectiveness, design limited block then and need protrude the how little length of ring flange;
(3) heat-generating pipe of the present utility model is compared with existing water heater heat-generating pipe, its power density is below 13W/cm2, can effectively reduce the surface temperature of heat-generating pipe, improve its service life, simultaneously, the heating section level of heat-generating pipe is outwardly-bent, increases its area of dissipation, improve the efficient of heat exchange, further improve its service life;
(4) fixedly connected above the moment design each other of 20 millimeters distances and with ring flange at interval vertically through crooked single group heat-generating pipe two ends that make a circulation, can strengthen it and be subjected to force intensity, reduce the amplitude that heat-generating pipe swings up and down, effectively reduce the risk of heat-generating pipe and ring flange junction cracking;
(5) this kind of heating control apparatus except can with the supporting use of storage-type electric water heater, also can be widely used in instant electric water heater, quick-heating type electric water heater, air source water heater, solar water heater, Teat pump boiler, water purifier, sanitaryware etc. appliance water product.
