The front side plate 101, the rear side plate 102, the left side plate 103, the right side plate 104, the upper side plate 105 and the lower side plate enclose an installation space;
after the installation space is obtained, the installation space needs to be divided into areas. Wherein the installation space is divided into three areas from the area division. The three regions are a left region, a middle region, and a right region, respectively. The left side area is the left space position of the installation space, the middle area is the middle space position of the installation space, and the right side area is the right space position of the installation space.

For the audio power amplifier, the main heating element is a power tube. Therefore, the power tubes of the audio power amplifier device are independently welded in the PCB to form the first power tube plate 211 and the second power tube plate. In order to allow efficient heat dissipation from the first power tubesheet 211 and the second power tubesheet, the first power tubesheet 211 is thermally conductively coupled to the first heat sink 201.

The cold air exchanges heat with the second radiator 202, and absorbs heat from the second radiator 202. Through this circulation, the second radiator 202 is allowed to radiate heat from the second power tubesheet.
