The invention relates to the technical field of electrical heating, and provides a combined-type electrical heating pipe. The combined-type electrical heating pipe comprises a combination of a first U-shaped pipe and a second U-shaped pipe, and a first binding post of the first U-shaped pipe is connected with a second binding post of the second U-shaped pipe; the combined-type electrical heating pipe also comprises a third U-shaped pipe, a third binding post of the third U-shaped pipe is connected with the first binding post and the second binding post, and the binding posts are isolated fromone another through insulating glue; the three U-shaped pipes are provided with spacers used for separating the three U-shaped pipes from one another, and the third binding post of the third U-shapedpipe is fixed on one end of each of the other two U-shaped pipes through a fixed part According to the invention, the three U-shaped pipes are employed to form the combined-type electrical heating pipe, the problem that for the combined-type electrical heating pipe, the surface heating power is too high, and heating is not uniform is solved, the heating area of the combined-type electrical heatingpipe is increased, a series of production problems caused by that the surface heating power is too high are reduced, and the service life of the electrical heating pipe is prolonged.
Description
technical field [0001] The invention relates to the technical field of electric heating, in particular to a combined electric heating tube for heating liquid. Background technique [0002] At present, the low-power sleeve-type electric heating tubes on the market mainly use one or two U-shaped tubes combined, and the main material is 304 stainless steel; there is no spacer, and the terminal post is not filled with insulating glue for insulation; the existing combined type The structure of the electric heating tube has the following two disadvantages: [0003] 1. The sleeve is circular. If there are only 1 or 2 U-shaped combined heating tubes built in, the surface heating will be extremely uneven, and the load on the side that has been heated for a long time will be heavy, and the heating power of the sleeve surface will be too high. The service life of the heated liquid is shortened and it is easy to oxidize; [0004] 2. At present, the insulation of the heater in our coun...
