Abstract
An aircraft light unit is disclosed herein. The aircraft light unit includes a housing having a first side and an opposing second side, a light coupled to the first side of the housing, a circuit board assembly coupled to second side of the housing, a thermoelectric cooler coupled to the circuit board assembly and configured to dissipated heat from the circuit board assembly, and a heat sink disposed over the thermoelectric cooler and configured to dissipate heat from the thermoelectric cooler.
Claims20
An aircraft light unit, comprising:
- a housing having a first side and an opposing second side;
- a light coupled to the first side of the housing;
- a circuit board assembly coupled to second side of the housing;
- a thermoelectric cooler coupled to the circuit board assembly and configured to dissipated heat from the circuit board assembly;
- and
- a heat sink disposed over the thermoelectric cooler and configured to dissipate heat from the thermoelectric cooler.
A light unit comprising:
- a circuit board assembly;
- a temperature sensor connected to the circuit board assembly;
- a thermoelectric cooler coupled to the spacer;
- a processor;
- and
- a memory coupled to the processor, the memory comprising instructions when executed by the processor cause the processor to:
- receive a first temperature reading from the temperature sensor, the temperature reading providing an indication of the temperature of the circuit board assembly;
- activate the thermoelectric cooler in response to the first temperature reading exceeding an operation temperature threshold;
- receive a second temperature reading from the temperature sensor, the second temperature reading providing a second indication of the temperature of the circuit board assembly;
- and
- deactivating the thermoelectric cooler in response to the second temperature reading being below the operation temperature threshold.
A cooling stack for a circuit board assembly, comprising:
- a spacer disposed over the circuit board assembly;
- a thermoelectric cooler disposed over the spacer;
- an insulator disposed over the spacer and adjacent the thermoelectric cooler;
- and
- a heat sink disposed over the thermoelectric cooler, the heat sink having a plurality of fins extending away from the thermoelectric cooler.
