Abstract
A wireless charger is provided. The wireless charger includes a housing, a baffle, a coil module, a circuit board, and a fan. The housing defines a mounting cavity, a first vent, and a second vent. The baffle is disposed in the mounting cavity and divides the mounting cavity into a first chamber and a second chamber. The coil module is disposed in the second chamber. The circuit board is disposed in the mounting cavity and electrically connected to the coil module. The fan, disposed in the first chamber and configured to guide air to flow into the first chamber from one of the first vent and the second vent and guide the air to flow out of the first chamber from the other of the first vent and the second vent, such that the air at the second vent exchanges heat with the electronic device.
Claims19
A wireless charger, comprising:
- a housing, defining a mounting cavity, a first vent, and a second vent, wherein the housing is configured to hold an electronic device with the second vent facing the electronic device;
- a baffle, disposed in the mounting cavity and dividing the mounting cavity into a first chamber and a second chamber, wherein both the first vent and the second vent are fluidly coupled to the first chamber, the first chamber is fluidly coupled to the second chamber, and a part of the housing defining the second chamber defines another vent fluidly coupled to the second chamber;
- a coil module, disposed in the second chamber;
- a circuit board, disposed in the mounting cavity and electrically connected to the coil module, and
- a fan, disposed in the first chamber and configured to:
- guide air to flow into the first chamber from one of the first vent and the second vent and guide the air to flow out of the first chamber from the other of the first vent and the second vent, such that the air at the second vent exchanges heat with the electronic device;
- and
- guide the air to flow into the first chamber and the second chamber from one of the first vent and the other vent and guide the air to flow out of the mounting cavity from the other of the first vent and the other vent.
