Abstract
Examples of the present disclosure relate to systems and methods for providing cooling and/or heating in a vehicle. For example, the systems and methods may cool and/or heat a vehicle cabin while the vehicle’s engine is not idling or otherwise in operation, without consuming excessive power stored by a vehicle battery. In example implementations, thermoelectric cooling cells may be used.
Claims20
A thermoelectric cooling system for a vehicle cabin, the thermoelectric cooling system comprising:
- a heatsink in thermal communication with an exterior of a vehicle cabin;
- one or more thermoelectric cells positioned within the vehicle cabin, each of the one or more thermoelectric cells having a first side and a second side, the second side mounted to the heatsink;
- a power supply electrically connected to the one or more thermoelectric cells;
- wherein, in response to receiving power from the power supply, the one or more thermoelectric cells are operable to produce a temperature difference between the first side and the second side, thereby drawing heat from the vehicle cabin to the heatsink.
1 more element
A method for cooling a vehicle cabin, the method comprising:
- receiving a desired temperature of the vehicle cabin;
- determining a current temperature of the vehicle cabin;
- determining a temperature difference between the desired temperature and the current temperature;
- based on determining the temperature difference indicates the desired temperature is lower than the current temperature:
- causing one or more thermoelectric cells to receive power from a power supply, wherein the thermoelectric cells have a first side and a second side, the second side mounted to a heatsink in thermal communication with an exterior of a vehicle cabin;
- and
- in response to response to receiving power, the one or more thermoelectric cells are operable to produce a temperature difference between the first side and the second side, thereby drawing heat from the vehicle cabin to the heatsink.
