Abstract

The utility model relates to a triangular fin, and belongs to the technical field of application of radiators. The triangular fin comprises a fin body 1, wherein the fin body 1 has the wave pitch L greater than or equal to 3mm but smaller than or equal to 5mm, the wave height H greater than or equal to 10mm but smaller than or equal to 12mm, the bending angle Phi greater than or equal to 13 degrees but smaller than or equal to 17 degrees, and the section pitch N greater than or equal to 8mm but smaller than or equal to 12mm. Under the same working condition, compared with a radiator manufactured from the triangular fin having the wave pitch greater than or equal to 4.5mm but smaller than or equal to 7mm, the wave height greater than or equal to 9mm but smaller than or equal to 9.5mm, the bending angle greater than or equal to 18 degrees but smaller than or equal to 24 degrees, and the section pitch greater than or equal to 5mm but smaller than or equal to 8mm, a radiator manufactured from the triangular fin provided by the utility model has the advantages as follows: through decrease of the wave pitch and increase of fin height, the radiating area of the fin is improved by 17% when the fin length is the same, the performance of a radiator is improved by 15% when the head-wind speed is the same, and the radiating performance is improved by 7.8% when the pump power is the same.

Description

A kind of triangle fin

Technical field

The utility model relates to a kind of triangle fin, belongs to heat sink applications technical field.

Background technology

Engineering machinery (as digging machine, rig etc.) is in the process of operation, and the hydraulic oil in its hydraulic system can produce a large amount of heat, and this part heat must be forced by radiator cooling.There is at present louvered fin, perforate fin has very high heat exchange efficiency, but operating mode is severe while work due to engineering machinery, adopts louvered fin or perforate fin easily to cause fin to stop up as the outer fin of radiator, thereby affect the long-term behaviour of radiator.What current most engineering machinery adopted is triangle radiating fin, it is high that triangle fin has intensity, the feature of easy cleaning, but along with the development of main frame, the placing space of radiator requires more and more less, adopts traditional triangle fin under certain space limited case, to be difficult to meet the radiator requirement of engineering machinery.

Summary of the invention

In order to overcome the defect existing in prior art, the utility model object is to provide that a kind of heat dispersion is high, the triangle fin of easy cleaning.

To achieve these goals, the utility model is by the following technical solutions:

A kind of triangle fin, comprises fin body 1, and the pitch of waves L of described fin body 1 is 3≤L≤5mm, and wave height H is 10≤H≤12mm, and bending angle Φ is 13 °≤Φ≤17 °, and pitch N is 8≤N≤12mm.

The pitch of waves L of described fin body 1 is 3.8mm, and wave height H is 11mm, and bending angle Φ is 15 °, and pitch N is 10mm.

Under identical operating mode, adopting radiator that triangle fin described in the utility model makes and the pitch of waves is that 4.5mm～7mm, wave height are that 9mm～9.5mm, bending angle are that the radiator of 18 °～24 °, the pitch triangle fin making that is 5mm～8mm is compared: the pitch of waves reduces the increase with fin height, under identical finned length, the area of dissipation of fin has improved 17%, under identical face velocity, radiator performance has improved 15%, and under same pump power, heat dispersion improves 7.8%.
