en Extended-range heat transfer fluid using variable composition By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT The present invention provides systems and methods for transferring heat using a variable composition organic heat transfer fluid that remains liquid over a wide operating temperature range useful for solar heating applications. Variable composition heat transfer fluids of the present invention comprise a miscible mixture, optionally a completely miscible mixture, of a high boiling point component selected for its beneficial high temperature physical properties, and a low freezing point component selected for its beneficial low temperature physical properties. In some embodiments, the low freezing point component is removed from the heat transfer fluid as the heat transfer fluid is heated, for example by being removed in the vapor phase, thereby selectively varying the composition and physical properties (e.g., vapor pressure, boiling point, etc.) of the heat transfer fluid as a function of temperature.

en Window mounting for thermal expansion in an oven appliance By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT Mounting for a window in an oven appliance is provided so as to allow for thermal expansion during oven use. More particularly, an expansion zone is provided around the window such that, during heating of the window from oven operation, the window is allowed to expand without restraint that could cause cracking or shattering. Space can be allowed for both lateral and longitudinal expansion of the window. Full Article
en Oven By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT An oven having enhanced cooling efficiency. The oven includes a cooking chamber, a door to open or close a front side of the cooking chamber, a cooling fan located above the cooking chamber to suction and blow outside air, a discharge duct to discharge the air, blown by the cooling fan, forward of the door, a plurality of flow-paths defined in the door to allow outside air to be introduced into and moved in the flow-path in association with discharge of the air through the discharge duct, and a suction pipe to connect at least one of the flow-paths and the cooling fan to each other. Suction force of the cooling fan is applied to the flow-paths of the door through the suction pipe as well as the interior of an electric machine room, allowing the air in the flow-path to be discharged to the outside through the suction pipe and the discharge duct. This assures more active air movement in the door and maximizes the cooling effect of the door. Full Article
