Abstract

The utility model relates to a radiating fin, including big piece and small piece, its characterized in that still includes the line that generates heat, the line that generates heat is arranged along the inside pipeline that big piece and small are constituteed. Because the heat conducting oil is not arranged in the radiating fin, the phenomena of oil leakage caused by poor welding and expansion caused by overhigh oil pressure do not exist, the problem of expansion caused by oil leakage of the oil heater and overhigh oil pressure of the radiating fin is solved, and the use safety of the product is greatly improved. The structure is simple and reasonable, the assembly is easy, the performance is reliable, and the service life is long.

Description

A kind of fin

Technical field

The utility model relates to a kind of fin of warmer, belongs to the improvement technology of the heat radiating fin structure of warmer.

Background technology

Oily spit of fland fin is in the past limited by solder technology, and leakage of oil can appear in fin, the unfavorable conditions such as sheet that rise, and complex structure.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, is easy to assemble, the fin of the structure of dependable performance.

The technical scheme that realizes the object of the invention is: a kind of fin, comprise sheet and small pieces, and it is characterized in that also comprising the heating line, said heating line is arranged along internal duct large stretch of and that small pieces are formed.

The two ends inboard at said small pieces are respectively arranged with more than one coiling clip, and an end is provided with fixed card, and said heating line is fixed through fixed card, and the heating line is wrapped on the coiling clip.

Said fixed card is strip, and at the draw-in groove that is provided with on the fixed card more than two, said heating line shuttles back and forth on each draw-in groove and fixes.

Said sheet and small pieces form through no rivet.

The utility model advantage compared with prior art is: simple and reasonable, fin need not oil-filled, and the heating line connects up along pipeline; Can evenly generate heat,, not have the leakage of oil and the too high sheet phenomenon that rises that causes of oil pressure that cause because of failure welding owing to do not have conduction oil in the fin; Solve the too high sheet problem of bringing that rises of leakage of oil of oily spit of fland and fin oil pressure, greatly improved the security that product uses, be easy to assembling; Dependable performance, long service life.

Description of drawings

Fig. 1 is the small structure sketch map of the utility model;

Fig. 2 is the explosive view of the utility model;

Fig. 3 is the enlarged drawing of the right portions of Fig. 2.

The specific embodiment

To combine accompanying drawing and embodiment that the utility model is described further below.

Shown in Fig. 1 to 3, a kind of fin comprises sheet 1 and small pieces 4, and the utility model characteristics are also to comprise heating line 2, and said heating line 2 is arranged with the internal duct of small pieces 4 compositions along large stretch of 1.

Be respectively arranged with more than one coiling clip 5, one ends at said small pieces 4 inboard two ends and be provided with fixed card 3, said heating line 2 is fixing through fixed card 3, and heating line 2 is wrapped on the coiling clip 5; In the present embodiment, be provided with five coiling clips 5 at small pieces 4 inboard ends, the other end is provided with three coiling clips 5, and the quantity of coiling clip 5 also can be set according to the actual needs of internal duct.

Said fixed card 3 is strip, and at the draw-in groove 31 that is provided with on the fixed card 3 more than two, said heating line 2 shuttles back and forth on each draw-in groove and fixes; In the present embodiment, on fixed card 3, be provided with six draw-in grooves 31, the quantity of draw-in groove 31 also can be set according to the actual needs of internal duct.

In the present embodiment, said large stretch of 1 form through no rivet with small pieces 4.

More than be the preferred version of the utility model, those of ordinary skills all drop within the protection domain of the utility model its simple distortion or transformation.
