Abstract

The utility model relates to a radiation slice. A bottom plate of the radiation slice is almost of trapezoid and a radiation rib connected with the bottom plate is perpendicular with the bottom. The radiation rib and any ray through the rotary round disk center are inclined and the inclined angle of the radiation rib and the connection line of the bottom plate gravity center and the rotary round disk center may be 10-55 degrees. The inclined angle of the radiation rib may be left inclined angle or left inclined angle, wherein the left inclined angle type radiation slice is suitable for the counter-clockwise rotation round disk and the right inclined angle type radiation slice is suitable for the clockwise rotation round disk. The radiation slice is mounted on the round disk to rotate in the air medium and the noise generated by the air flow is relative small.

Description

A kind of fin

Technical field

The utility model relates to a kind of fin.Be particularly useful for being fixed on the fin of rotation heating parts end face.

Background technology

Fin generally adopts making as metal materials such as copper, aluminium of high heat conductance, and its shape is generally straight trough shape, as Fig. 1～fin shown in Figure 2, a symmetrical center line is arranged, and all radiation ribs all are parallel to symmetrical center line.Base plate and heating parts bonding or Bolt Connection, the multi-disc linear fin parallel to each other that is connected with the base plate heat that parts pass to base plate that will generate heat is dispersed in the surrounding medium.When on fin is used to rotate the garden plate-like heating parts, the symmetrical center line of each fin overlaps with a certain ray by disc centre; Fin is around the rotation of garden disk axis, and air flows the fin notch of overflowing at a high speed under the rotary centrifugal force effect, when rotating speed is higher, will form ear-piercing whistler.

The utility model content

The utility model provides a kind of fin.It is trapezoidal that base plate is approximately, and the radiation rib that is connected with base plate is perpendicular to base plate, and radiation rib all is rendered as skewed with arbitrary ray by the rotating circular disk center.The inclination angle of radiation rib and base plate center of gravity and the rotating circular disk line of centres can be 10 °～55 °.The inclination angle of radiation rib can be left-leaning angle, also can be the Right deviation angle, and left-leaning angle type fin is applicable to anti-clockwise disk, and Right deviation angle type fin is applicable to the disk that turns clockwise.

The utility model fin is installed on the disk and rotates in air dielectric, and the noise that the air miscarriage is given birth to is less.
