Embodiment Construction

[0034] see figure 1 , the preferred embodiment of the heat sink of the present invention is used for fixing on a circuit board to dissipate heat from electronic components. The heat sink includes a base 10 with a plurality of cooling fins 12 disposed on the base 10 . Two buckling devices are disposed on opposite sides of the base 10 , and each buckling device includes a fixing part 20 fixed on the base 10 , a pivoting part 30 , two elastic elements 40 and a buckling part 50 . In this embodiment, the elastic element 40 is a spring.

[0035] The fixing member 20 is roughly U-shaped, and includes a fixing portion 21 fixed on the base 10 and two parallel arm portions 22 , each arm portion 22 defines a pivot hole 221 on opposite sides.

[0036] The pivoting member 30 is substantially square, and a through hole 32 is defined in the center thereof. Two opposite sides of the pivot member 30 protrude outward from a pivot shaft 34 respectively.

[0037] The buckle 50 is dumbbell-sha...

Abstract

The invention relates to a radiator. The radiator comprises a base, a fixed piece, a pivoting piece and a fastening piece, wherein the fixed piece is fixed on the base; the pivoting piece is pivoted on the fixed piece; the fastening piece is arranged on the pivoting piece; and the two ends of the fastening piece are respectively provided with a first fastening part and a second fastening part which are respectively used for fixing the radiator at different circuit boards. The invention also provides a fastening device of the radiator. Compared with the prior art, the radiator has the advantage that the fastening piece is pivoted on the base of the radiator by the pivoting piece, so that the radiator fixing mode can be changed. The radiator can be applicable to different circuit boards.

Description

technical field [0001] The invention relates to a radiator and a buckle device thereof. Background technique [0002] A heat sink is often used on the circuit board to assist in heat dissipation. The fixing method of the heat sink is generally only suitable for one installation environment, and cannot be used in other installation environments, which will limit the use environment of the heat sink. Contents of the invention [0003] In view of the above, it is necessary to provide a heat sink with multiple fixing methods and its snap-fitting device. [0004] A heat sink, comprising a base, a fixing part fixed on the base, a pivoting part pivoted on the fixing part and a buckle part arranged on the pivoting part, two ends of the buckle part are respectively provided with a first A buckle part and a second buckle part, the first buckle part and the second buckle part are respectively used to fix the radiator to different circuit boards. [0005] A buckle device, used to bu...
