Radio tray assemblies
Described herein are radio tray assemblies that include space for a specific radio and its power supply and that additionally provide cooling and power conversion and control functionalities. The disclosed radio tray assemblies are designed to have a form factor compatible with legacy radio systems (e.g., MIDS-LVT) while enabling installation of a new radio system (e.g., MIDS-JTRS). The disclosed radio tray assemblies are configured so that the radio and its power supply are secured to a tray so that the radio and power supply are side-by-side and parallel lengthwise. A cooling module or assembly of the disclosed radio tray assemblies is disposed immediately behind the radio and its power supply and is configured to cool these units using forced air cooling directed lengthwise through the radio and its power supply. A power converter and controller module converts input power into the power required by the radio power supply.
1. A radio tray assembly comprising:
a tray forming a radio mounting portion and a radio power supply mounting portion adjacent to the radio mounting portion, the radio mounting portion configured to receive a radio and the radio power supply mounting portion configured to receive a radio power supply;
a cooling module secured to the tray adjacent to the radio mounting portion and to the radio power supply mounting portion, the cooling module configured to provide cooling by directing air through the radio mounting portion; and
a controller module secured to the tray and configured to implement a cooling control algorithm to control the cooling module, the cooling control algorithm configured to adjust cooling based at least in part on power output by the radio power supply mounted to the tray.
2. The radio tray assembly of claim 1 , wherein the controller module is further configured to monitor the radio power supply to determine the power output by the radio power supply.
3. The radio tray assembly of claim 1 , wherein the controller module is further configured to provide electrical power to the cooling module.
4. The radio tray assembly of claim 3 , wherein the controller module is further configured to adjust the electrical power provided to the cooling module to adjust the provided cooling, adjustments to the electrical power determined by the cooling control algorithm.
5. The radio tray assembly of claim 1 , wherein the controller module comprises a power converter configured to provide electrical power to the radio power supply.
6. The radio tray assembly of claim 5 , wherein the controller module is further configured to measure an electrical current out of the power converter to determine power dissipation of the radio and radio power supply.
7. The radio tray assembly of claim 6 , wherein the controller module is further configured to adjust the provided cooling based at least in part on the determined power dissipation.
8. The radio tray assembly of claim 1 , wherein the cooling module is further configured to provide feedback electrical signals to the controller module.
9. The radio tray assembly of claim 8 , wherein the feedback electrical signals are configured to indicate fan speed, fan voltage, fan power, or fan state of a fan that is part of the cooling module.
10. The radio tray assembly of claim 8 , wherein the cooling control algorithm is configured to use the feedback electrical signals from the cooling module to adjust the provided cooling.
11. A method of providing cooling for a radio tray assembly having a tray with a radio portion and a radio power supply portion, a radio being mounted on the radio portion and a radio power supply mounted on the radio power supply portion, the method comprising:
directing air through the radio portion of the radio tray assembly to provide cooling to the radio mounted to the radio portion; and
adjusting the provided cooling using a cooling algorithm that controls an amount of air directed through the radio portion, the cooling algorithm configured to adjust the provided cooling based at least in part on power output by the radio power supply.
12. The method of claim 11 further comprising monitoring the radio power supply to determine the power output by the radio power supply.
13. The method of claim 11 further comprising providing electrical power to a cooling module mounted to the tray, the cooling module configured to direct the air through the radio portion to provide the cooling.
14. The method of claim 13 further comprising adjusting the electrical power provided to the cooling module to adjust the provided cooling, adjustments to the electrical power determined by the cooling control algorithm.
15. The method of claim 11 further comprising providing electrical power to the radio power supply.
16. The method of claim 15 further comprising measuring the electrical power provided to the radio power supply.
17. The method of claim 16 further comprising determining power dissipation of the radio and the radio power supply based at least in part on the measured electrical power provided to the radio power supply.
18. The method of claim 17 further comprising adjusting the provided cooling based at least in part on the determined power dissipation.
19. The method of claim 11 further comprising receiving feedback electrical signals that indicate fan speed, fan voltage, fan power, or fan state of a fan directing the air through the radio portion.
20. The method of claim 19 , wherein adjusting the provided cooling by the cooling control algorithm is based at least in part on the feedback electrical signals.
