A cooling apparatus and method, and more particularly, an apparatus and method for cooling the air exiting an electronics enclosure, are disclosed. Air is taken into the enclosure and heated by the electronic equipment. The air is then expelled through a heat exchanger, which cools the exiting air. The exiting air is cooled using an external source of cooling liquid, which absorbs the heat from the exiting air. This absorbed heat is then expelled from the liquid outside of the environment containing the enclosure. Cooling the air exiting the enclosure causes the enclosure to present a neutral heat load to a room containing such an enclosure. Cooling the exiting air obviates the necessity of increasing the room air conditioning capacity to account for the heat added to the room by the electronics within the enclosure. Further, the disclosed apparatus and method decrease the possibility of moisture condensation within the enclosure and also provide more efficient cooling than is available from prior art devices and techniques.

An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a pipe to heat the pipe which in turn heats the water flowing therethrough. The heater is highly efficient due to the direct contact of the wet heating surface with the water and provides a smooth seamless inner heating surface by eliminating the need to pass electrical leads into the wet region of the heater. This virtually eliminates the risk of leaks in the water heater due to bulkhead fittings. The invention further eliminates the need for a heating element to be contained in the inner wet region of a spa heater, thereby reducing the risk of corrosion. The water heater is used in combination with an electronic controller having a microprocessor to control and regulate the operation of the water heater. The water heater can be used with electrical, electro-mechanical, and mechanical control systems for spas and can be retrofitted into existing spa applications.

The invention described in this disclosure is an apparatus and method for clamping semiconductor wafers or other substrates or workpieces during etching, CVD, or surface modification processes. The purpose of the invention is to achieve improved heat transfer during processing between the wafer / substrate and a temperature controlled pedestal used for supporting it in the process chamber. The typical level of process heat put into the wafer during plasma-based etching or deposition processes will be up to about 10 Watts per centimeter squared while the maximum acceptable temperature differential between wafer / substrate and pedestal is less than about 100 Celsius. In such low gas pressure environments typical for plasma-based processes, the heat removal from the wafer / substrate by gaseous conduction may be inadequate to meet requirements. This invention achieves excellent heat transfer to the pedestal from the wafer / substrate when there is a thin, resilient, electrically insulating layer (tape) bonded to the wafer / substrate or the pedestal. Wafer / substrate clamping for improved process heat removal is achieved by a combination of vacuum clamping of the wafer / substrate beginning prior to evacuation of the processing chamber, along with or followed by electrostatic clamping of the wafer / substrate which continues during processing. The invention also permits the wafer / substrate to be rapidly and safely released from the electrostatic clamping when the chamber is returned to atmospheric pressure by a providing a slight pressure increase, above atmospheric pressure, between wafer and pedestal. The pedestal may have some roughening or narrow grooves on the wafer clamping surface, and some small holes from its surface leading to an evacuated plenum or channel within the pedestal. Alternatively, the pedestal may have a layer of a porous metal extending from its surface down to the evacuated channel or plenum which permits gas to be evacuated. These structures allow vacuum pumping of gas that might otherwise be trapped between the insulating layer and the pedestal. When a wafer / substrate is placed on the pedestal by loading at atmospheric pressure, vacuum pumping through the pedestal is commenced. This causes the workpiece to be pressed to the pedestal clamping surface with approximately atmospheric pressure compressing the soft layer against its clamping surface. This provides sufficient contact of the soft layer with the pedestal to greatly improve heat transfer from the wafer / substrate to the pedestal. A voltage is applied to the pedestal, beginning any time after the wafer is on the pedestal, to further clamp the wafer electrostatically. As the processing chamber is then pumped down to operating pressure for processing the electrostatic clamping voltage maintains sufficient pressure of the wafer / substrate against the pedestal to maintain the heat conductive contact between the soft layer and the pedestal. This permits good heat conduction to be maintained during the low pressure plasma-based etching or CVD processing. Following processing when the wafer / substrate is to be removed it may be rapidly de-clamped from the electrostatic clamping by application of a slight over-atmospheric pressure in the reservoir or pumping channels within the pedestal.

Improvements in systems and methods which employ a two-phase fluid, such as a refrigerant, as a saturable fluid in direct heat transfer relation to a thermal load, are realized by extraction of vapor from the saturated fluid before heat exchange.

The present invention relates to thermosyphons, in particular for use in the cooling of electronic components.
