  • Patent number: 10049176
    Abstract: The invention relates to a method of determining characteristics of orifices (O1, . . . , O9) to be made through a plate (2) positioned in a circuit (10) across the fluid passage. Said method comprises defining fluid data, the number of orifices, and for each orifice a control segment or area. The fluid flow rate through each orifice of the perforated plate is calculated, and for each orifice, the flow rate density is calculated by dividing said fluid flow rate by the associated control segment length or control area. The optimized or non-optimized nature of the orifice characteristic is determined by comparing said flow rate density with the mean flow rate density. If the difference in absolute value lies within a predetermined range of values, then the orifice characteristics are considered as being optimized. Otherwise at least one characteristic of at least some of the orifices is modified.

A pair of core plates 53 and 54 is assembled in such a way that the side of the core plate 53 on which the protrusion 10 is not formed faces the side of the core plate 54 on which the protrusion 10 is not formed and the protrusions 10 and 10 formed on the respective core plates are paired but oriented in opposite directions. The pair of core plates 53 and 54 form a plurality of tubes surrounded by the walls of the protrusions 10 and 10, and the tubes form high temperature fluid compartments.

  • Patent number: 8797169
    Abstract: A system for sensing and indicating orientation of electrical equipment comprises an orientation sensor and control logic. The control logic is configured to compare predefined data with an orientation of the electrical equipment sensed by the orientation sensor in order to determine whether the sensed orientation of the equipment is within an acceptable range such that sufficient cooling by a cooling system is likely to occur. If the sensed orientation of the equipment is not within the acceptable range, the control logic transmits a notification signal so that corrective action can occur. As an example, the notification signal may be used to notify a user of the improper orientation. In another example, the notification signal automatically triggers an action that compensates for the improper orientation.

  • Patent number: 8757246
    Abstract: A heat sink includes a fluid channel and a cooling wall in contact with coolant flowing in the fluid channel. The channel is configured to vary the velocity of coolant along the length of the fluid channel to vary the coolant's heat transfer coefficient and thereby compensate for the coolant's temperature rise along the length of the fluid channel. The result is a heat sink that is isothermal along its length.

  • Patent number: 8695687
    Abstract: A hybrid pin-fin micro heat pipe heat sink consists of a plurality of heat pipes secured to a base. The heat pipes have a generally hollow cross-section which transitions from a first cross-sectional shape (e.g., circular) to a second cross-sectional shape (e.g., triangular). A heat transfer medium (e.g., saturated steam) is sealed within the heat pipes. Cooling plates may be disposed over the base with the heat pipes in physical contact with and passing through the cooling plates. The method of manufacturing the heat pipes consists of passing a heat transfer medium through a pipe section having a first cross-sectional shape while transitioning to a second cross-sectional shape (e.g., by way of a rolling die press), then crimping the ends closed to seal the heat transfer medium therein.

    Abstract: An apparatus sometime referred to as a freeze pipe and methods of using these apparatus in ground freezing applications is provided. Ground freezing is a temporary ground support technique that is used extensively for groundwater control and ground stabilization in underground construction and deep excavations. The process involves circulating refrigerated liquids through a series of vertically disposed “freeze” pipes to freeze the ground creating a solid barrier that prevents water intrusion and provides structural support for excavation. The freeze pipes are directed to “zone freeze” pipes or the like, which cause the ground to freeze in selected segments along the pipe, also referred to as zones.

  • Patent number: 8439104
    Abstract: Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that include multichannel tube configurations designed to reduce refrigerant pressure drop through a heat exchanger manifold. In certain embodiments, tubes inserted within the manifold adjacent to a refrigerant inlet have non-rectangular or recessed end profiles configured to increase flow area near the inlet, thereby reducing a pressure drop through the manifold. In further embodiments, insertion depths of the tubes within the manifold vary based on distance from the inlet. This configuration may establish a larger flow area adjacent to the inlet, thus reducing the pressure drop and increasing heat exchanger efficiency.
