US Patent:

55071503, Apr 16, 1996

Filed:

Feb 4, 1994

Appl. No.:

8/192026

Inventors:

Richard M. Weber - Propser TX
Donald C. Price - Dallas TX
Byron E. Short - Fairview TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

F25B 1900

US Classification:

62100

Abstract:

A thermal management system using an expendable liquid which undergoes phase change to a vapor as waste heat is absorbed and also possesses a high latent heat of vaporization. The vapor is expelled, carrying with it the waste heat. A vacuum source lowers the vapor pressure to lower the vaporization temperature. In first embodiments, regulated fluid flows into a heat exchanger wherein a vacuum system lowers the pressure. Waste heat transported to the heat exchanger by a coolant loop causes the liquid to boil at a desired temperature. A flow regulator controls the rate of fluid flow from the pressurized reservoir to the heat exchanger. The refrigeration effect is produced by the liquid being converted from the liquid to the vapor phase and absorbing heat from the coolant fluid during the phase change. The vacuum system provides a system pressure that results in a suitable temperature at which vaporization occurs. The fluid flow is controlled, based upon the demand from the heat load produced.

Appl. No.:

9/397486

Inventors:

James L. Haws - McKinney TX
Byron Elliott Short - Fairview TX

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01Q 138

US Classification:

343700MS

Abstract:

An antenna system (10) includes circuitry (13) and an antenna unit (12). The antenna unit includes a multi-layer circuit board (21). The circuitry provides radio frequency signals, control signals and power to the circuit board. The circuit board has an array of antenna elements (23) on one side thereof, and has a plurality of modules (71, 72) soldered to and projecting outwardly from the opposite side thereof. The modules each have electronic circuitry thereon, which is electrically coupled to the circuit board. Each module includes a thermal transfer element (96), the heat generated by the electronic components on that module being thermally transferred by the thermal transfer element to a cooling section (51).

Appl. No.:

11/428004

Inventors:

James Haws - McKinney TX, US
Byron Short - Fairview TX, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H04B 1/38
H04M 1/00

US Classification:

455561000

Abstract:

A cooling apparatus () includes a housing defined by two aluminum parts () which are brazed to each other. A plurality of sector-shaped recesses (-) are provided within the housing, and collectively define a chamber having a plurality of ribs (-) extending therethrough. Each recess contains a sector-shaped piece of porous material (), which is brazed to surfaces of the housing parts. The remaining space within the chamber is filled with a phase change material. Each of the ribs has therein a respective radially extending opening (-) which contains a heat pipe (). Expansion accumulators () are mounted on the housing, and communicate with the chamber therein, in order to accommodate expansion of the phase change material within the chamber as the phase change material is heated.
