Description

A kind of flat tube and fin type heat exchanger fin

Technical field:

This utility model relates to technical field of refrigeration equipment, a kind of flat tube wing Plate heat interchanger fin.

Background technology:

Fin is the vitals of the heat exchanger in refrigeration plant, existing heat exchanger many employings U Shape pipe is fixed on fin by tube expansion mode, uses the mode of tube expansion so that fin and pipe Between contact surface between body, contact is closely, but carries out there is conduction heat during conduction of heat between the two Resistance, have impact on its heat transfer effect.Another angle-inserting type heat exchanger, its pipe is curved by S type Pipe inserts in fin, and fin and pipe contact area are not full circle, between the two a contact surface Inherently few, heat transfer effect is limited.

Therefore, use now flat tube to be fixed on fin and realize heat exchange, and existing flat tube compares Thin, when the U-shaped flat tube using flat, (i.e. U-bend pars convoluta is the level identical with flat straight portion Flat form) insert fin long through groove in time, its need use push rod by U-shaped flat tube U-bend pars convoluta promotes and stretches out from long through groove so that two flat straight portions of U-shaped flat tube stretch into In long through groove, thus make the thickness of push rod need less than or be equal to the thickness of flat tube, this Sample is when two flat straight portions of U-shaped flat tube are long, and push rod is accomplished by the longest, and push rod is long, And thickness low LCL, intensity declines, is easily bent, and thus leverages U-shaped flat tube peace The effect being contained on fin, impact is installed.

Utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of flat tube and fin type Heat exchanger fin, it is by arranging installation groove at the middle part of the long through groove of fin, and prolongs Stretch the notch that correspondence is set on body so that the thickness of the push rod installing U-shaped flat tube can be more than U The thickness of shape flat tube, it is ensured that its rigidity so that push rod will not bend when promoting, improves and installs effect Fruit and efficiency.

This utility model solves the scheme of described technical problem:

A kind of flat tube and fin type heat exchanger fin, including fin body, in described fin body It is provided with the multiple long through grooves for flat tube sleeve, the wall of the fin body of the edge of long through groove On there is extension body, in the middle part of two sidewalls up and down of long through groove, there is installation groove, install The middle part of the top and bottom sidewall extending body that groove is corresponding has notch, notch and installation groove phase Corresponding.

Described fin body is provided with multiple flowing through hole.

All flowing through holes are distributed on above and below long through groove.

Have to the front or behind of fin body oblique on one medial wall of described flowing through hole The wind deflector extended.

In adjacent two flowing through holes, the wind deflector of a flowing through hole is to the front of fin body Extending obliquely out, the wind deflector of another flowing through hole extends obliquely out to the rear of fin body.

On the unidirectional medial wall of all flowing through holes, there is wind deflector.

The middle part of four sidewalls of described fin body all forms heating plate and places groove, heating Plate is placed has extension bending plate on the sidewall of groove.

Prominent effect of the present utility model is:

Compared with prior art, it is recessed by arranging installation at the middle part of the long through groove of fin Groove, and extend the notch that correspondence is set on body so that the thickness of the push rod of U-shaped flat tube is installed Can be more than the thickness of U-shaped flat tube, it is ensured that its rigidity so that push rod will not bend when promoting, Improve and effect and efficiency are installed.

Detailed description of the invention:

Embodiment, is shown in as shown in Figures 1 to 5, a kind of flat tube and fin type heat exchanger fin, Including fin body 10, described fin body 10 is provided with leads to for the multiple elongated of flat tube sleeve Groove 11, the wall of the fin body 10 of the edge of long through groove 11 has extension body 12, There is in the middle part of two sidewalls up and down of long through groove 11 installation groove 13, groove 13 is installed right The middle part of the top and bottom sidewall extending body 12 answered has notch 14, and notch 14 is recessed with installation Groove 13 is corresponding.

Further, described fin body 10 is provided with multiple flowing through hole 1.

Further, all flowing through holes 1 are distributed on above and below long through groove 11.

Further, a medial wall of described flowing through hole 1 has to fin body 10 The wind deflector 2 that extends obliquely out of front or behind.

Further, in adjacent two flowing through holes 1, the wind deflector of a flowing through hole 1 2 extend obliquely out to the front of fin body 10, another flowing through hole 1 wind deflector 2 to The rear of fin body 10 extends obliquely out.

Further, the unidirectional medial wall of all flowing through holes 1 has wind deflector 2。

Further, the middle part of four sidewalls of described fin body 10 all forms heating Groove 3 placed by plate, and heating plate is placed has extension bending plate 4 on the sidewall of groove 3.

In the present embodiment, it is by having installation in the middle part of two sidewalls up and down of long through groove 11 Groove 13, the middle part of the top and bottom sidewall extending body 12 installing groove 13 correspondence has groove Mouth 14, notch 14 is corresponding with installing groove 13 so that flat at the U-shaped installing flat Guan Shi, the thickness of its push rod can be more than the thickness of U-shaped flat tube so that its rigidity improves, no Can bend, improve and effect is installed.

Meanwhile, the wind deflector 2 that the flowing through hole that it is provided with is provided with produces disorderly when making to blow air over Flow phenomenon, improves heat transfer effect.

And, in the present embodiment, it installs groove 13 and notch 14 is exactly in U-shaped flat tube Two flat straight portions between dead slot at so that its heat exchange do not interfere with U-shaped flat tube two are flat The heat transfer effect in straight portion.

Shown in Fig. 5, after the sidewall of multiple fin body 10 is close to be pressed against mutually, heating plate 100 Two the corresponding heating plates that can be placed on two adjacent fin body 10 place groove 3 In, meanwhile, extend bending plate 4 and be close to heating plate 100 wall, thus improve heat transfer effect.

Finally, embodiment of above is merely to illustrate this utility model, and not new to this practicality The restriction of type, about the those of ordinary skill of technical field, without departing from essence of the present utility model In the case of god and scope, it is also possible to make a variety of changes and modification, the most all equivalents Technical scheme falls within category of the present utility model, and scope of patent protection of the present utility model should be by Claim limits.
