Proportional Micro-Valve With Thermal Feedback

Номер: US20120012299A1
Автор: Randall N. Avery
Принадлежит: Industrial Idea Partners Inc

A proportional micro-valve for regulating the temperature of an electronic component comprising a cooling subsystem associated with each thermal zone of the electronic component, a cooling circuit carries cooling fluid to a heat exchanger associated with each thermal zone, the flow of which is controlled by a valve element, which is in turn controlled by a sensing circuit which reacts to the temperature of the underlying thermal zone to proportionally increase or decrease the rate of cooling fluid flowing through the heat exchanger based upon the temperature of the thermal zone. Cooling fluid substantially continuously flows through the sensing circuit, regardless of whether the valve element is open or closed. The sensing circuit provides feedback to a temperature-responsive mechanical amplifier for opening and closing the valve element.

The system and methods are applicable for use in Lab-on-a-Chip (LoC) technology, and can be useful in the implementation of reconfigurable LoC devices. Routes through the bus are determined by control signals and/or sequences of control signals issued under algorithmic control. Several independent flows may occur simultaneously. Adaptations of Clos, Banyan, and other related multi-stage switching architectures in the flow topology can be supported. Sensors are placed at various locations along bus path segments. Information gathered by the sensors can be used for one or more of controlling measured flows, clearing operations, cleaning operations, and control of the timing flow transport. The sensors can be of one or more types such as presence sensors, flow sensors, pressure sensors, temperature sensors, conductivity sensors, optical sensors, ion sensors, and affinity sensors.

Micromechanic passive flow regulator

Номер: US20120316492A1
Автор: Eric Chappel
Принадлежит: Debiotech SA

The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane ( 1 ), a middle plate ( 2 ) with pillars and through holes and a bottom plate ( 3 ) with fluidic ports, micro channels and through holes ( 8,9,12 ). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane. For implanted pump, the use of a flow regulator instead of a flow restrictor has several advantages, including the possibility to reduce significantly the reservoir pressure and to generate directly the pressure during the pump filling by using an elastic drug reservoir.

A water-saving device structure is provided. When the pressure of an entry water is high, a water-barrier sheet body is pressed to cause a downwardly-moved elastic stopping portion to block a water-inflow opening of a water-outflow seat body, so that the water flow is conducted to a water-outflow opening through a water-conducting opening of the water-barrier sheet body. When the pressure of the entry water is low, the entry water is conducted to the water-outflow opening via one path traveling from the water-conducting opening of the water-bather sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of stopping wall portions of the water-outflow seat body, a water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained.

A pressure and flow calculation technique can be used in a distributed process network simulation system that uses the sequential solving method to perform better or faster simulations of a process flow, especially with respect to process junction nodes at which flow either converges or diverges. The pressure and flow variable determination technique uses a grouped node identification technique that identifies a local set of nodes for each junction node of the process network to use when solving for the pressure at the junction node, a grouped node iteration technique that uses the grouped set of nodes at each junction node to perform iterative pressure calculations at the junction node, and a flow-based pressure calibration technique at each junction node to enable the system to perform highly accurate pressure and flow variable determination at each junction node in real-time.

A spool valve includes a housing having a spring-enclosing portion and a spool-enclosing portion aligned along a longitudinal axis. A spool is mounted for reciprocal axial movement in the housing and a piston is fixed to one end of the spool. The spool-enclosing portion supports a stationary bushing having a bore receiving an opposite control end of the spool, the bushing formed with a first plurality of radially-oriented passages opening into an annular groove formed in the bore, the groove having sloped side edges. The spool supports plural ring-seals arranged to engage the sloped side edges of the annular groove and thereby seal off the radially-oriented passages when the spool is in a neutral position. Movement of the spool is adjustably limited in one direction and dampened in both axial directions.
