Description

TECHNICAL FIELD

[0002] As an important component of 3C equipment, the battery is increasingly required to have high performance with the progress of science and technology. Higher performance means greater power and heat. As one of the main heat generating devices, the temperature control of the battery is an unavoidable issue for 3C equipment. At present, many designs of battery composition still choose to package the battery and the circuit board in a glue shell, especially in VR equipment.

[0003] The existing 3C equipment cooling solutions mainly include two kinds. One is an external heat dissipation device, for example, many consumers will externally place a heat dissipation back clip to cool the phone when playing games to ensure smoothness. However, this will additionally increase a set of equipment and the equipment needs to have a separate power supply system, which is not flexible and practical. The other is that the 3C equipment actively reduces power consumption when the NTC detects that the temperature of the battery and other heat generating devices is too high, thereby reducing the heat generation. This will sacrifice the smoothness of the equipment and reduce the user experience. CONTENT OF THE INVENTION

During the process that the airflow enters the first heat dissipation channel 510 from the air inlet 13 and is discharged from the air outlet 14, the airflow can take away the heat on the heat dissipation plate 50 and the first heat dissipation pipe 51, so that good cooling and heat dissipation effects are achieved.
