Detailed Description

In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1, an upper header pipe; 2: a lower header pipe; 3: a branch pipe; 4: an electric heating rod; 5: a heat exchanger fin; 51: a front heat sink; 52: a rear heat sink; 6: connecting sheets; 7: outer sleeve, 8: and (5) long sewing.

In order to show more information, in fig. 1, the heat exchanger fins are connected to the branch pipes on the left part, the branch pipes are directly shown on the right part, the components shown by the reference numerals are shown, the current electric heater of the barrel is the same, and the barrel is also provided with a junction box, a switch, a support frame and corresponding fasteners and wire pipes, which are not innovative points of the present application.

As shown in the attached drawing, the electric heating piece capable of electrically activating phase change latent heat comprises an upper main pipe 1 and a lower main pipe 2 in the horizontal direction, a plurality of branch pipes in the vertical direction are welded between the upper main pipe and the lower main pipe, 3 the shape and the size of each branch pipe are the same, the branch pipes are communicated with the interior of the upper main pipe and the interior of the lower main pipe, the lower main pipe is internally provided with an electric heating rod 4 which is sealed in the lower main pipe, the phase change heat storage agent is filled in each pipe of the heating radiator, the radiating fins are connected to each branch pipe, each radiating fin comprises a front radiating fin 51 and a rear radiating fin 52, two connecting pieces in a shape like a Chinese character 'ba' are fixedly connected to the inner surfaces of the front radiating fin and the rear radiating fin, the connecting pieces are shown as 6, the inner ends of the two connecting pieces are fixedly connected to the outer wall of an outer sleeve 7, each branch pipe penetrates through the corresponding outer sleeve, and each branch pipe is fixedly connected with the corresponding outer sleeve. The connecting structure for fixedly connecting each branch pipe and the corresponding outer sleeve is as follows: the branch pipe and the outer sleeve pipe are welded together, and figure 2 is an embodiment of welding together, and the welding only needs to position the upper and lower ports of the outer sleeve pipe on the branch pipe for spot welding together. The welding between the radiating fins and the outer sleeve is very convenient in the mode, and the welding can be carried out in parallel with the welding between the upper main pipe, the lower main pipe and the branch pipe, so that the working efficiency is improved. Because the outer tube can reciprocate, so when carrying out the welding operation between branch pipe and upper header pipe, the lower header pipe, can form great clearance through removing the outer tube, can increase the heat exchanger fin area like this, the defect that this kind of structure exists is because expend with heat and contract with cold can produce the clearance between long-time use branch pipe and the outer tube, influences the heat transfer effect, and this defect can be overcome to next kind of connected mode that leaves the long seam.

Fig. 3 shows another embodiment of the connection structure for the fixed connection between each branch pipe and the corresponding outer sleeve, the outer sleeve is an open pipe with a long seam 8 formed on the whole length of the pipe wall, the inner diameter of the outer sleeve is less than or equal to the outer diameter of each branch pipe, the open pipe is sleeved outside each branch pipe, and after the branch pipes are inserted into the outer sleeve, the circumferential arc length of the opening part of the long seam is 3-9 mm.

Because the long seam is arranged, the branch pipe is tightly matched and inserted with the outer sleeve, the outer sleeve can expand with heat and contract with cold along with the branch pipe, no gap is formed between the outer sleeve and the branch pipe, and the phenomenon of poor heat exchange cannot be caused even after long-time use.

After the embodiments of the present invention have been described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above claims, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments of the examples given in the specification.
