Description

The new radiator of anti-blocking

Technical field

The utility model relates to radiator field, more particularly, relates to a kind of new radiator of anti-blocking.

Background technology

In the industries such as spinning, weaving, chemical fibre, printing and dyeing, the operational environment of frequency converter is faced with that dust is many, batting is many, pollute the problem such as heavily.These dust, batting can enter heat dissipation channel along air inlet, and pile up between the radiating fin of radiator, and likely make the heat dissipation channel of frequency converter block, thus affect heat sinking function, cause frequency converter alarm overheated.

For avoiding cooling air channel to block, current frequency converter for textile industry adopts following structure usually:

(1) radiator is not with fan, uses blower fan naturally to cool by frequency converter.But the radiating efficiency of this structure is limited, be only applicable to the frequency converter of 3.7KW and following power section, applicability is little.

(2) by increasing the gap of the radiating fin 12 on radiator base plate 11, while reaching predetermined radiating effect, the percent of pass (as shown in Figure 1) of dust, batting etc. is improved.But this structure will make the volume of radiator very large, impact assembling and use.And this type of radiator section is an angle of 90 degrees, section is simple deburring process, for reducing the adhesiving effect of cotton-wool and not obvious.

Utility model content

The technical problems to be solved in the utility model is, easily adheres to dust, batting and the problem causing heat dissipation channel to block, provide a kind of new radiator of anti-blocking for above-mentioned radiator.

The technical scheme that the utility model solves the problems of the technologies described above is, a kind of new radiator of anti-blocking is provided, comprise substrate, multiple first radiating fin and multiple second radiating fin, wherein: described first radiating fin and the second radiating fin are arranged on substrate in the mode be parallel to each other, and described first radiating fin and the second radiating fin spaced apart; The air inlet lateral edges of described first radiating fin and the second radiating fin and the angle of substrate are all less than 90 °, and the angle of the air inlet lateral edges of the first radiating fin and substrate is greater than the air inlet lateral edges of the second radiating fin and the angle of substrate.

In the new radiator of anti-blocking described in the utility model, the air inlet lateral edges of described first radiating fin be oblique angle or fillet away from a jiao of substrate.

In the new radiator of anti-blocking described in the utility model, the air inlet lateral edges of described second radiating fin be oblique angle or fillet away from a jiao of substrate.

In the new radiator of anti-blocking described in the utility model, described first radiating fin and the second radiating fin have the surface through polishing respectively.

In the new radiator of anti-blocking described in the utility model, the spacing between the first adjacent radiating fin and the second radiating fin is equal.

In the new radiator of anti-blocking described in the utility model, described first radiating fin and the second radiating fin are arranged on substrate in the mode perpendicular to substrate surface.

In the new radiator of anti-blocking described in the utility model, the angle of described first radiating fin and substrate is greater than 70 ° and is less than 90 °.

In the new radiator of anti-blocking described in the utility model, the angle of described second radiating fin and substrate is 60-70 °.

The new radiator of anti-blocking of the present utility model has following beneficial effect: by changing the structure of radiating fin air inlet side, the air inlet of radiator cooling air channel is made to produce turbulent flow, produce the counter blow with air intake direction different directions, thus reduce the adhesive ability of batting and dust, and then alleviate the impact that the accumulation because of cotton-wool etc. causes frequency converter.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 2,3, be the schematic diagram of the new radiator embodiment of anti-blocking of the present utility model, this radiator may be used in the equipment such as frequency converter, dispels the heat with auxiliary.The new radiator of the anti-blocking in the present embodiment comprises substrate 21, multiple first radiating fin 22 and multiple second radiating fin 23, wherein the first radiating fin 22 and the second radiating fin 23 are arranged on the base plate (21 in the mode be parallel to each other, and the first radiating fin 22 and the second radiating fin 23 spaced apart.Above-mentioned first radiating fin 22 and the air inlet lateral edges of the second radiating fin 23 and the angle of substrate 21 are all less than 90 ° (namely the air inlet lateral edges of the first radiating fin 22 and the second radiating fin 23 and substrate 21 place plane keep an angle of inclination), and the air inlet lateral edges of the first radiating fin 22 and the angle of substrate 21 are greater than the air inlet lateral edges of the second radiating fin 23 and the angle (the air inlet lateral edges of namely adjacent radiating fin is different relative to the angle of inclination of substrate 21 place plane) of substrate 21.

By the first radiating fin 22 and the incline structure of the second radiating fin 23 in air inlet side, the air inlet of radiator cooling air channel can be made to produce turbulent flow, namely the counter blow with air intake direction different directions is produced, this counter blow can make the adhesive ability of a small amount of batting and dust entering air inlet with air-flow reduce, and the air outlet along the gap of radiating fin through radiator is discharged from cooling air channel, can not pile up at air inlet, thus solve the impact that the accumulation because of cotton-wool etc. causes frequency converter.

The new radiator of above-mentioned anti-blocking can many at dust such as spinning, weaving, chemical fibre, printing and dyeing, batting is many, pollute heavy environment under use, avoid the accumulated plugging of weaving batting, dust on the impact of the equipment use performances such as frequency converter, and structure is simple, integral heat sink ventilation effect is better.

Especially, for reducing the adhesive ability of dust, batting further, the air inlet lateral edges of above-mentioned first radiating fin 22 and the second radiating fin 23 be oblique angle or fillet away from a jiao of substrate 21.

In addition, the first radiating fin 22 and the second radiating fin 23 can have the surface through polishing respectively.Relative to the radiator only section being done to simple deburring process, the adhesive ability of dust, batting reduces further.

With existing radiator similarly, spacing between the first radiating fin 22 adjacent in the new radiator of above-mentioned anti-blocking and the second radiating fin 23 is equal, and above-mentioned first radiating fin 22 and the second radiating fin 23 are to arrange on the base plate (21 perpendicular to the mode on substrate 21 surface.Certainly, also can according to concrete environment for use, change the first radiating fin 22 and the second radiating fin 23 distribution mode at substrate 21.

When specific implementation, the first radiating fin 22 can be greater than 70 ° with the angle of substrate 21 and be less than 90 °.And the second radiating fin 23 can be 60-70 ° with the angle of substrate 21.

The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
