Abstract

In some embodiments, a cooling system for an induction charger includes a thermal conditioning module in fluid communication with an induction charging assembly, which includes a dock and an induction charging module. The dock can be configured to receive a portable electronic device, such as a cell phone, that is configured to accept inductive charging from the induction charging module. The thermal conditioning module can include a fan or other fluid encouraging assembly, ducting, and a thermoelectric device (e.g., a Peltier device). A fluid, such as air, can flow from the fan and across and/or through the thermoelectric device, thereby conditioning the fluid. The conditioned fluid can be provided to the dock to at least partially offset the heat generated by the inductive charging and/or the portable electronic device.

Claims

1. A cooling system for an induction charging module, the system comprising:

a dock configured to connect to an induction charging module on a first side, the dock comprising;

walls defining a cavity, a first opening at a first end for receiving a portable electronic device within the cavity, and a second opening on a second side of the dock adjacent a second end opposite the first end; and

at least one rib protruding from at least one of the walls on the first side for spacing the portable electronic device away from the at least one of the walls; and

a thermal conditioning module comprising an air moving device and a duct fluidly connecting the air moving device and the dock via the second opening,

wherein during operation, the thermal conditioning module supplies a flow of air into the dock for cooling the portable electronic device.

2. The cooling system of claim 1, wherein the system is disposed in an automobile.

3. The cooling system of claim 1, wherein the portable electronic device comprises a cell phone.

4. The cooling system of claim 1, wherein the thermal conditioning module moves air via the air moving device and the duct from the second end of the dock to the first end of the duct along at least a portion of the portable electronic device.

5. The cooling system of claim 4, wherein the thermal conditioning module moves air via the air moving device and the duct from the second end of the dock to the first end of the duct along the at least a portion of the portable electronic device by the air moving at least partially along the at least one rib in the spacing between the at least one of the walls and the portable electronic device.

6. The cooling system of claim 1, wherein the at least one of the walls is configured to connect to the induction charging module.

7. The cooling system of claim 1, wherein the system is configured to at least partially offset the heat generated by the induction charging module during induction charging of the portable electronic device.

8. The cooling system of claim 1, wherein the system is configured to provide at least about 6 watts of heat dissipation.

9. The cooling system of claim 1, wherein the thermal conditioning module further comprises a thermoelectric device that cools the flow of air supplied to the dock.
