Abstract
A two-phase cooling system for a portable computer which in one embodiment consists of an evaporator which is positioned within the base of the computer and a condenser which is positioned within or attached to the lid of the computer. The evaporator and the condenser are connected by flexible tubing. The tubing may run externally from the lid to the base or it may extend through one or more of the hinges that connect the base and the lid. In an alternative embodiment, both the evaporator and the condenser of the two-phase system are incorporated into either the base or the lid of the computer.
Claims31
A laptop computer including:
- A. case with a lid for housing a screen and a base for housing a keyboard and heat producing electronic circuitry;
- B. a two-phase cooling system with an evaporator and a condenser connected by tubing,
- wherein the evaporator is enclosed in the base and the condenser is attached to an external wall of the lid.
A laptop computer including:
- A. a case with a lid for housing a screen and a base for housing a keyboard and heat producing electronic circuitry;
- B. a two-phase cooling system with an evaporator and a condenser connected by tubing,
- wherein the evaporator is enclosed within the base and the condenser is enclosed within the lid.
A laptop computer including:
- A. a case with
- i. a lid for housing a screen with a front face and a rear face, the lid including a top wall that covers the rear face of the screen, and
- ii. a base for housing a keyboard and heat producing circuitry;
- and
- B. a two-phase cooling system with
- i. an evaporator,
- ii. a condenser with a front wall and a back wall, and
- iii. tubing connecting the evaporator and the condenser,
- wherein the evaporator is enclosed within the base and the condenser is enclosed within the lid, the back wall of the condenser being integral with the top wall of the lid.
A two-phase cooling system for a laptop computer with a lid that houses a screen and a base that houses a keyboard and heat producing circuitry, the cooling system including:
- A. an evaporator shaped to fit within the base and proximate to the heat producing circuitry;
- B. a condenser with a front wall and a back wall;
- C. a bracket for attaching to the lid, the bracket holding the condenser;
- and
- D. tubing connecting the evaporator and the condenser.
A laptop computer including:
- A. a case with a lid for housing a screen and a base for housing a keyboard and heat producing electronic circuitry;
- and
- B. a two-phase cooling system with an interconnected evaporator and condenser, the evaporator residing in close proximity to the heat producing circuitry and the condenser being supported by the lid.
