Embodiment 1

[0030] Such as figure 1 with figure 2 As shown, a bowl-type flange submerged thick-film heater includes a flange 1, a first heating substrate 2, a second heating substrate 3, insulating paper 4 and a temperature detection tube 6, and the first heating substrate , the second heating substrate, and insulating paper constitute the thick film heating body 8 . The lower edge of the thick film heater is offset from the axis of the flange by 15 cm.

[0031] According to the requirements of the diving depth of the first heating substrate and the second heating substrate, both the first heating substrate and the second heating substrate are arc-shaped, and the single surface area of ​​the first heating substrate and the second heating substrate is designed to be 250cm². One end of the first heating substrate has a first extending end 9, and one end of the second heating substrate has a second extending end 10. The mirror images of the substrates overlap, and the first protruding en...

Embodiment 2

[0036] Such as Figure 5 As shown, both the first heating substrate and the second heating substrate are S-shaped, with a large degree of curvature, and the others are the same as those in Embodiment 1.

Embodiment 3

[0038] Such as Image 6 As shown, on the basis of Embodiment 1, the preset positioning sheet 7 is added, and the ends of the first extension end 9 and the second extension end 10 of the thick film heating body are passed through the rectangular through hole 12 of the flange, so that the preset The positioning piece is closely attached to the lower end surface 14 of the flange, and the gap between the positioning piece and the lower end surface of the flange is preset by laser sealing welding thick film heating body; Laser sealing and welding the gap between the temperature detection tube and the lower end surface of the flange; spraying fluororesin on the lower end surface 14 of the flange, the outer surface of the thick film heating body, and the outer surface of the temperature detection tube. Finally, the power connection line and the lead connection end 5 are welded by soldering, and then the concave surface of the flange is potted with silica gel, so as to strengthen the ...

Abstract

The present invention proposes a thick film heater, which includes a bowl flange, a thick film heating body and a temperature detection tube. The bottom of the flange is provided with a rectangular through hole and a circular through hole. The thick film heating body After passing through the rectangular through hole, it is sealed and welded with the flange, and the temperature detecting tube is sealed and welded with the flange after passing through the circular through hole of the flange. The invention saves materials, has low cost, simple welding process, saves labor and time, has better heat preservation effect, better use performance, wider adaptability, more convenient mass production, and is convenient for general assembly of water heaters. It is high-quality and reliable in terms of safety performance, anti-corrosion and anti-scaling performance, service life and product stability and reliability.

Description

technical field [0001] The invention relates to the technical field of electric heating devices for fluids, in particular to a bowl-type flange submerged thick-film heater. Background technique [0002] Storage-type electric water heaters are favored by people because of their convenient installation and use. However, traditional storage-type electric water heaters have large volumes, low heating tube efficiency, and slow heating speeds, which have become a huge drawback. [0003] Thick-film heaters have extremely high thermal efficiency, and gradually entered the field of electric water heaters. However, due to the traditional thick-film heaters, the power is large and the area is small, the performance of the heating plate is extremely unstable, easy to scale, and the design of the flange cover makes installation difficult. High heat loss and other reasons have seriously affected the popularization and application of the technology. [0004] Although many existing new tec...
