Radiator fixing structure and its assembling method

Abstract

The invention is a heat dissipater fixing structure which is used for circuit board, wherein the circuit board has a first surface, a second surface and a connecting part; a plurality of electric elements are arranged on the first surface. The heat dissipater fixing structure as a minimum includes a heat dissipater arranged on the first surface of the circuit board and having a first part, a second part extending outwards from the first part, and a connecting part, at least one guide connecting part arranged on the first surface of the circuit board and having a first connecting part connectedwith and fixed onto the connecting part of the circuit board, and a second connecting part connected with and fixed onto the connecting part of the heat dissipater to fix the dissipater on the firstsurface of the circuit board. The heat dissipater fixing structure and its assembling method prevent inconvenience for operators caused by turning the circuit board during assembling operation, and can simplify the assembling procedure and reduce assembling time and labor cost.

Description

technical field [0001] The present invention relates to a heat sink fixing structure and an assembly method thereof, in particular to a heat sink fixing structure and an assembly method thereof which use an adapter device to assist in fixing the heat sink on a circuit board. Background technique [0002] Radiators have been widely used in various electrical equipment to help solve the problem of heat dissipation inside the electrical equipment. For example, various heat sinks are usually arranged on the circuit board inside the power supply device to transfer the heat generated by the electronic components on the circuit board to the housing to dissipate heat when the power supply device is running. However, as the power of the power supply device increases, the heat sink also develops towards reducing the thermal resistance and increasing the heat dissipation area, so heat sinks of various shapes are produced accordingly, so how to fix various heat sinks on the circuit boar...
