Effect is difficult to reach expected, so it is easily damaged circuit board.
Utility model content
The main purpose of the utility model is to provide a kind of power amplifier cooling fins, are mostly installed in power amplifier box and are used for
The fixed monoblock power amplifier circuit board of installation, it is convenient to fasten, and stable strong after installation plays power amplifier circuit board the effect of heat dissipation.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of power amplifier cooling fin, including the first heat sink body being fastened and connected and the second cooling fin sheet can be mutually paired
Body, the first heat sink body and the second heat sink body are L-shaped structure, and one end of the first heat sink body is equipped with bayonet, the
One end of two heat sink bodies is equipped with for fastening installation to the fixture block of bayonet, to make the first heat sink body radiate with second
Piece ontology is fastened and connected together, and the first heat sink body inside corresponding with the second heat sink body is equipped with toward indent for blocking
Enter the card slot of power amplifier circuit board is installed, the first heat sink body outside corresponding with the second heat sink body has been respectively uniformly distributed
First radiating fin, first heat sink body and the second heat sink body are equipped with for entire cooling fin to be fixed on work(
Put the adjusting mounting groove in machine.
Further, the second radiating fin is distributed in the surface of first heat sink body and the second heat sink body.
Further, fixed screw is equipped in the adjusting mounting groove.
The utility model has the advantages that：This cooling fin is made of two pieces of independent heat sink body fastenings, is used
In the installation of power amplifier box interior circuit board, two pieces of heat sink bodies are equipped with adjusting mounting groove, can be according to the length of power amplifier circuit board
It is short to be adjusted, can be widely applied to the installation of various Electron Equipment Circuit Boards, by way of simply directly fastening and with
Fixed screw, which is fixed after fastening is integrated, keeps monolithic stability firm, not will produce any loosening, with traditional connection structure
It compares, monoblock power amplifier circuit board can be made to obtain best heat dissipation effect, and very convenient, the saving set-up time is installed.
