Abstract

A system configured to provide thermal regulation and vibration isolation to one or more electronic components. The system includes a sensor chassis defining an interior chamber, an electronics housing in the interior chamber of the sensor chassis, a thermoelectric cooler coupled between the sensor chassis and the electronics housing, a thermal strap coupled to the sensor chassis, and at least one isolator coupled to the sensor chassis. The system may also include an insulating material, such as Aerogel, in the interior chamber of the sensor chassis and extending around the electronics housing.

First claim

What is claimed is:

1. A system configured to provide thermal regulation and vibration isolation, the system comprising:
a sensor chassis defining an interior chamber;
an electronics housing in the interior chamber of the sensor chassis;
a thermoelectric cooler coupled between the sensor chassis and the electronics housing;
a thermal strap coupled to the sensor chassis; and
at least one isolator coupled to the sensor chassis.

2. The system of claim 1 , further comprising an insulating material in the interior chamber of the sensor chassis, the insulating material extending around the electronics housing.

3. The system of claim 2 , wherein the insulating material comprises Aerogel.

4. The system of claim 1 , wherein the thermal strap comprises first and second copper blocks and a plurality of copper wires extending between the first and second copper blocks.

5. The system of claim 4 , wherein the thermoelectric cooler is coupled to a portion of an inner surface of the sensor chassis, and the first copper block of the thermal strap is coupled to a portion of an outer surface of the sensor chassis opposite the portion of the inner surface.

6. The system of claim 1 , further comprising at least one clamp coupling the electronics housing to the sensor chassis.

7. The system of claim 6 , wherein the at least one clamp comprises polyether ether ketone.

8. The system of claim 1 , wherein the at least one isolator comprises:
a primary chamber;
a backpressure chamber;
a liquid contained in the primary chamber and the backpressure chamber;
a conduit extending between the primary chamber and the backpressure chamber, the conduit placing the primary chamber in fluid communication with the backpressure chamber;
a backpressure membrane defining at least a portion of the backpressure chamber;
an elastomer dome defining at least a portion of the primary chamber; and
a shaft having a first end coupled to the elastomer dome and a second end coupled to the sensor chassis.

9. The system of claim 1 , wherein the at least one isolator comprises a first isolator coupled to a first end of the sensor chassis and a second isolator coupled to a second end of the sensor chassis opposite the first end.

10. The system of claim 1 , wherein the electronics housing comprises aluminum.

11. A drill system, comprising:
a drill string;
a pressure casing coupled to the drill string;
a sensor chassis defining an interior chamber, the sensor chassis being housed in the pressure casing and spaced apart from the pressure casing by a gap;
an electronics housing in the interior chamber of the sensor chassis;
an insulating material in the interior chamber of the sensor chassis, the insulating material extending around the electronics housing;
a thermoelectric cooler coupled between the sensor chassis and the electronics housing;
a thermal strap extending across the gap, the thermal strap having a first end coupled to the sensor chassis and a second end coupled to the pressure casing; and
at least one isolator coupled between the pressure casing and the sensor chassis.

12. The drill system of claim 11 , wherein the insulating material comprises Aerogel.

13. The drill system of claim 11 , wherein the thermal strap comprises first and second copper blocks and a plurality of copper wires extending between the first and second copper blocks.

14. The drill system of claim 13 , wherein the thermoelectric cooler is coupled to a portion of an inner surface of the sensor chassis, and the first copper block of the thermal strap is coupled to a portion of an outer surface of the sensor chassis opposite the portion of the inner surface.

15. The drill system of claim 11 , further comprising at least one clamp coupling the electronics housing to the sensor chassis.

16. The drill system of claim 15 , wherein the at least one clamp comprises polyether ether ketone.

17. The drill system of claim 11 , wherein the isolator comprises:
a primary chamber;
a backpressure chamber;
a liquid contained in the primary chamber and the backpressure chamber;
a conduit extending between the primary chamber and the backpressure chamber, the conduit placing the primary chamber in communication with the backpressure chamber;
a backpressure membrane defining at least a portion of the backpressure chamber;
an elastomer dome defining at least a portion of the primary chamber; and
a shaft having a first end coupled to the elastomer dome and a second end coupled to the sensor chassis.

18. The drill system of claim 11 , wherein the at least one isolator comprises a first isolator coupled to a first end of the sensor chassis and a second isolator coupled to a second end of the sensor chassis opposite the first end.

19. A method of thermally and vibrationally isolating a payload, the method comprising:
inserting a thermoelectric cooler into an interior chamber of a sensor chassis;
inserting an electronics housing accommodating the payload into the interior chamber and onto the thermoelectric cooler;
injecting an insulating material into the interior chamber and around the electronics housing; and
connecting a thermal strap to the sensor chassis.
