the utility model provides a fin convenient to clearance filth, includes the bottom plate, bottom plate lower surface be equipped with the mounting structure who is used for installing electronic component, it has a plurality of fin A to distribute at the last perpendicular surface of bottom plate, fin A's both ends be equipped with the sleeve pipe, be equipped with the montant at the last fixed surface of the bottom plate at sleeve pipe place, montant upper portion be equipped with the external screw thread, the sleeve pipe cover locate outside the montant to through with external screw thread complex nut with the sleeve pipe with fin A extrusion fixed, when the extrusion is fixed, fin A's lower extreme offset with the upper end of bottom plate.

Preferably, the upper surface of the bottom plate where the lower ends of the fins A are located is provided with a limiting groove, the lower ends of the fins A are integrally formed with a flange, and the flange is inserted into the limiting groove and is abutted against the groove bottom and the groove wall of the limiting groove.

Preferably, the vertical rods and the limiting grooves are arranged in a row to form a fin A mounting structure, the fin A mounting structure is provided with a plurality of rows, and the rows are arranged in parallel.

Preferably, the row of any one of the fin a mounting structures is provided with a fin a, and a fin B is further connected between adjacent fins a.

Preferably, the fins a and the fins B are intersected with each other to form a matrix structure.

Preferably, the fins a and the fins B are both provided with vent holes.

Preferably, the vent holes of all the fins A form a matrix arrangement; the vent holes of all the fins B also form a matrix arrangement.

Preferably, the ventilation holes are in a circular or rectangular or polygonal structure.

Preferably, the surfaces of the fins a and B are coated with nano carbon materials.

This novel fin's convenient to clearance filth beneficial effect does: this is novel not only can guarantee the radiating effect, and the fin is convenient to be dismantled, receives between the fin and pollutes or when blockking up, and the detachable fin thoroughly clears up fast, makes the fin resume heat dispersion, has avoided filth to block up the defect that the clearance is troublesome, can harm electronic component even.
