Filed: 1998-07-21
Granted: 2001-02-11
Abstract: Apparatus and method for sub-ambient cooling using thermoelectric element dynamics in conjunction with pulsed electrical power and selectively enabled thermal coupling to the cold sink. In one form, Peltier devices are dynamically enabled using pulses of electrical power while the thermal path between the cold side of the Peltier device and the cold sink is selectively switched in relative synchronism between conductive states responsive to the dynamics of the Peltier device temperatures. Switched coupling of the thermal connection between the cold sink and the Peltier device materially improves efficiency by decoupling Joule heating and conductive heat transfer losses otherwise conveyed from the Peltier device. Preferable implementations utilizes MEMS to accomplish the selective thermal switching, whereby sub-ambient cooling capacity is increased by parallel operation of multiple Peltier devices and MEMS switches.

Abstract: An exhaust gas containing a perfluoride compound (PFC) and SiF4 is conducted into a silicon remover and brought into contact with water. A reaction water supplied from a water supplying piping and air supplied from an air supplying piping are mixed with the exhaust gas exhausted from the silicon remover. The exhaust gas containing water, air, and CF4 is heated at 700 DEG C by a heater. The exhaust gas containing PFC is conducted to a catalyst layer filled with an alumina group catalyst. The PFC is decomposed to HF and CO2 by the catalyst. The exhaust gas containing HF and CO2 at a high temperature exhausted from the catalyst layer is cooled in a cooling apparatus. Subsequently, the exhaust gas is conducted to an acidic gas removing apparatus to remove HF. In this way, the silicon component is removed from the exhaust gas before introducing the exhaust gas into the catalyst layer. Therefore, the surface of the catalyst can be utilized effectively, and the decomposition reaction of the perfluoride compound can be improved.
