Effect.
Preferably, the first installation indoor location has two spaced amplification modules parallel, each amplification module
Front rectify fan is mounted on to place.As amplification module is the core component of whole machine operation, the radiating relation of amplification module
To the quality of amplifier audio frequency output, therefore, one independent fan is set in the front end of each amplification module, it can be ensured that put
The heat that big module is produced is discharged in time, so as to ensure the stability of whole machine operation.
Preferably, the isolation baffle plate is plastics or metal baffle.By plastics or the iris action of metal baffle
Interference of the electromagnetic radiation to amplification module that can be produced with shielded transformer, strengthens the stability of whole machine operation.
Preferably, the air port on the first installation room thus can quickly exclude amplification with fan just to arranging
The heat that module is produced.
A kind of power amplifier high efficiency and heat radiation and the beneficial effect of anti-interference structure that this utility model is provided is:
(1) this power amplifier high efficiency and heat radiation and anti-interference structure design are simple, by transformator and amplify mould by isolation baffle plate
Block is separated, and can intercept the interference of the electromagnetic radiation to amplification module of transformator generation in practical work process, so as to can
To improve the signal to noise ratio of whole machine;
(2) this power amplifier high efficiency and heat radiation and anti-interference structure are narrow by forming one between isolation baffle plate and installing plate end edge
Narrow air channel, during fan exhaust, installs the air quantity of room uptake entrance as the obstruct of isolation baffle plate is made from second
With, the air channel for forcing radiation air to be formed from isolation baffle plate with installing plate end edge is flow through, and so, forces wind speed to be accelerated, from
And make the heat of the second installation interior generation quickly through discharging at fan, strengthen the radiating effect of the machine.
