A heat transfer device with reduced vertical section. The device includes a condenser with generally vertical internal cooling fins. The inlet directs the heat transfer fluid in vapor state to the top of the cooling fins where the vapor condenses and flows along the fins to the bottom of the condenser. The bottom of the condenser is angled towards the outlet to direct the liquid heat transfer fluid to a reservoir for holding the fluid. Both the inlet and the outlet are arranged at a height above the level of the heat transfer fluid in liquid state in the reservoir. The arrangement may also include fins on the exterior of the condenser to provide a cooling surface that is not in contact with the heat transfer fluid in liquid or vapor state.

In a projector assembly having a lamp for emitting light, and an ellipsoid reflector for capturing the light, the ellipsoid reflector having an opening through its vertex facilitating placement of the lamp, there is provided an improvement wherein the opening in the ellipsoid reflector is sized to allow a major portion of cooling air to pass therethrough into a region defined by the ellipsoid reflector. An air deflector is situated in the opening so as to facilitate distribution of cooling air along the lamp and outwardly towards the inside surface of said ellipsoid reflector from within said region.

A cooling device for use in an electric arc furnace is provided. The cooling device provides a novel and effective method for cooling burners, lances, enclosures, and other devices used in high heat environments, such as in Electric Arc Furnaces. According to one aspect of the invention used in a steel making process in an electric arc furnace, a cooling tube is inserted into a cooling cavity in a burner. Cooling fluid is injected through the cooling tube into the cavity to cool the portions of the burner adjacent the cooling cavity. The cooling fluid is then extracted from the cavity through a concentric space between the cooling tube and the cooling cavity. According to another aspect of the present invention, a cooling fluid distribution flange is provided to distribute cooling fluid to a plurality of cooling tubes to inject cooling fluid into a plurality of associated cooling cavities.

A drilling / reaming tool includes a basic body which extends in a longitudinal direction. The basic body includes at least one end-side drilling major cutting edge, a main flute which is assigned to said drilling major cutting edge and is wound at a first helix angle, and a plurality of reaming cutting edges which are arranged circumferentially on the basic body and have in each case one reamer flute which is assigned to the respective reaming cutting edge and is wound at a second helix angle. The reaming cutting edges adjoin the at least one major cutting edge directly in the longitudinal direction. Each reamer flute is merged into the main flute.

A cooling fan module for motivating air flow through an electronics chassis includes an enclosure having an air inlet through which cooling air flow is motivated by at least two centrifugal blowers disposed within the enclosure. The centrifugal blowers operate in parallel to motivate the cooling air flow along a first direction vector, while the respective axes of rotation of the centrifugal blower impellers are in substantial axial alignment with one another, and parallel to the first direction vector.

Accurate measurement and monitoring of a computer room air conditioning unit's cooling production, distribution, and consumption is necessary to optimize effectiveness and efficiency and minimize redundancy. A mass air flow monitoring device comprises an array of sensor modules and a controller module with display, user interface, and I / O for third party connectivity. The device monitors temperature, pressure, water content, and quantity of airflow in a CRAC's supply air stream and return air stream and compares the two measurements to determine the amount of energy, or enthalpy, put into or taken out of the air. The result, displayed in watts, allows for the efficient control of production, distribution, and usage of supply air from the CRAC unit. Over or under provisioning can be quickly identified and corrected and, when used in conjunction with power consumption monitoring, a “watts of cooling for watts of power consumption” efficiency metric can be provided.
