The purpose of the utility model can be realized through the following technical scheme:
the utility model provides a maintain convenient liquid heat-conducting medium heating device, includes the head, can dismantle a plurality of heating pipes of connecting on the head, the both ends of heating pipe pass the head respectively and stretch out, the tip of heating pipe be located the both sides of head and be equipped with retaining ring and nut respectively, the heating pipe pass through nut and retaining ring and can dismantle to be connected on the head.
Further, the heating pipe is a U-shaped heating pipe.
Furthermore, a plurality of unthreaded holes are formed in the end socket, and the end parts of the heating pipes are respectively positioned in the corresponding unthreaded holes.
Furthermore, a heating resistance wire is arranged in the heating pipe, and two ends of the heating pipe are respectively provided with a heating resistance wire terminal.
Furthermore, the end part of the heating pipe extending out of the end socket is provided with an external thread matched with the nut.
Furthermore, a washer is arranged between the nut and the seal head to prevent the seal head from being scratched by the nut and disperse the pressure of the nut on the seal head.
Furthermore, a sealing ring is arranged between the retainer ring and the end enclosure to prevent the heat-conducting medium from entering the heating pipe.
Furthermore, the sealing ring is a polytetrafluoroethylene sealing ring.
The working principle is as follows: the device abandons the traditional welding and fixing mode, adopts a threaded connection mode that a nut is matched with external threads at the end part of the heating pipe and is matched with a retaining ring, and realizes detachable connection between the heating pipe and the end socket;
when the heating device works, the heating pipe positioned on one side provided with the retainer ring is immersed into the liquid heat-conducting medium, the heating resistance wire is connected with an external power supply through the wiring end of the heating resistance wire, and the liquid heat-conducting medium is heated through the heating pipe.
Compared with the prior art, the utility model has the characteristics of it is following:
1) the maintenance is more convenient: the seal head and the heating pipe are assembled in a threaded connection mode, so that later maintenance and replacement are facilitated;
2) the sealing performance is good: the welding connection mode is easy to cause the heated heat-conducting medium to leak into the heating pipe due to incomplete welding, so that potential safety hazards are caused;
3) the heating pipe is made of metal materials, so that heat dissipation is more uniform.
