Abstract
The utility model discloses a sound box heat radiation apparatus, comprising a fan. The fan is fixed under a circuit board which is vertically mounted inside a sound box, a sound box wall corresponding to the fan is provided with an air inlet, and one or two air outlets are horizontally arranged at an upper part of the sound box.
Description
Affiliated technical field
The utility model belongs to heat abstractor, particularly audio amplifier heat abstractor, i.e. H04R.
Background technology
As everyone knows, the electro-acoustic element in audio amplifier needs heat radiation, usually adopts the fan forced ventilation.How to improve its radiating efficiency, get the brush-off so far.
The utility model content
The purpose of this utility model is to provide a kind of audio amplifier heat abstractor, and it has thermolysis preferably.
It is as follows that new technical scheme is disclosed:
A kind of audio amplifier heat abstractor contains fan at least, it is characterized in that vertically being fixed in the wiring board in voice box casing, and fan is equipped with in the below of wiring board, has air inlet on audio amplifier wall corresponding to fan, and there is the gas outlet top of audio amplifier wall.
The audio amplifier of making by such scheme, due to the gas outlet up, fan and air inlet below, forced convertion, also have the free convection circulation except the fan air draught, therefore radiating efficiency is preferably arranged.
Description of drawings
Figure is an embodiment cross-sectional schematic of the present utility model.
Wherein: 1, gas outlet 2, wiring board 3, heater members 4, fan
Embodiment
A kind of audio amplifier heat abstractor contains fan 4 at least, it is characterized in that vertically being fixed in the wiring board 2 in voice box casing, and fan 4 is equipped with in the below of wiring board 2, has air inlet on the audio amplifier wall of fan 4 correspondences, and there is gas outlet 1 top of audio amplifier wall.
On wiring board 2, heater members 3 is housed.
