18426 results about "Air cooling" patented technology

Air cooling is a method of dissipating heat. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both. An example of the former is to add cooling fins to the surface of the object, either by making them integral or by attaching them tightly to the object's surface (to ensure efficient heat transfer). In the case of the latter, it is done by using a fan blowing air into or onto the object one wants to cool. The addition of fins to a heat sink increases its total surface area, resulting in greater cooling effectiveness.

Heating and cooling control methods and systems

The present invention is related to the field of heating, ventilation and air conditioning (HVAC). More particularly, the present invention is related to methods and systems for controlled heating and cooling in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The present invention is directed to mathematical algorithms incorporated into a controller and a method of determining control signals that are dependent on said mathematical algorithms and user programming that integrates information from multiple sensors, thermostats as well as weather information. Used in any home or building, the controller controls heating, cooling and ventilation systems in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The controller works with typical HVAC systems generally in buildings and homes. The Smart-Stat algorithms are programmed into the controller and enable the controller to identify user-determined set-points alongside data from one or multiple internal temperature sensors. The user-determined set-points are also linked to time of day and day of week in a manner typical for typical thermostat devices available today. In such typical thermostat devices the controller will call for cooling or heating depending on the set points and conditions determined by the sensors in the building. The present invention is capable of interrupting the call for cooling or heating depending on whether the mathematical algorithms identify suitable outside weather conditions that permit the use of outside air cooling or outside air heating. Thus the call for heating or cooling can be redirected to call for ventilation instead of heating or cooling.

Apparatus and method for enhanced degassing of semiconductor wafers for increased throughput

A multi-level shelf degas station relying on at least two heaters integrated within wafer holding shelves or slots, where the semiconductor wafers do not have direct contact with the heater shelves. The heaters provide conduction heating. In order to degas a wafer, the heater and wafer holder assembly is positioned in a sequential manner through each wafer slot to the next available slot. If a degassed wafer exists in the slot, a transfer chamber arm removes it. A loader arm then places a wafer in the available, empty slot and the stage is moved upwards to receive the wafer from the loader arm. The transfer chamber arm removes an individual wafer from the heater and wafer holder assembly allowing the removed wafer to be individually processed while the other wafers remain in the heater and wafer holder assembly. In some instances, a loader arm may also remove wafers. The remaining wafers in the heater and wafer holder assembly are subjected to further degas treatment while the wafer(s) removed by the transfer chamber arm are exposed to other process steps. Air-cooling chambers are employed to facilitate cooling the wafer slots for ease of removal and maintenance.

A disk drive box 10 accommodates a plurality of disk drives 20 within a case 11. A side face of each of the drives 20 is provided with a heat-absorbing part 40 including a heat pipe, corresponding to heat producing area HP. The heat taken away by the heat-absorbing part 40 is transmitted to a heat sink 50 of the rear of a backboard 30 via a heat connector 60. The heat sink 50 is cooled by cooling air flowing through an air duct 7. By cooling the drive 20 with the heat pipe, clearances between the drives 20 can be substantially eliminated, and it is made unnecessary to form an opening for air cooling in the backboard 30. Thus, size reduction is possible, and it is possible to increase the degree of freedom for a wiring pattern formed on the backboard 30.
