  • Patent number: 8118482
    Abstract: A system for changing the temperature (T1) of a fluid such as an on-demand water heater is disclosed. The system comprises an input for receiving the fluid (120) at a first temperature (T1) and an output for delivering the fluid at a second temperature (T2). A conduit connects the input to the output, and comprising means such as a heating element for altering the temperature of the fluid from the first temperature (T1) to the second temperature (T2). The system is characterized by the presence of one or more virtual sensors for estimating the fluid temperature in a given location within the conduit. The system provides accurate fluid temperature control without suffering from the slow responsiveness that usually mars sensor-based systems.

  • Patent number: 8118481
    Abstract: A detector for identifying a fluid is disclosed. The detector comprises a probe having a thermistor, the probe being arranged to be exposed to a fluid and to allow thermal flow between the fluid and the thermistor; a temperature sensor to measure the ambient temperature of the fluid and a controller. The controller is arranged to supply electrical power to the thermistor and to provide an output indicative of the identity of the fluid based upon whether the electrical power supplied to the thermistor is above or below a threshold value. The threshold value is adjustable in accordance with the measured ambient temperature of the fluid. Examples of such a detector provide reliable fluid identification despite variations in ambient temperature of the fluid and such a detector may be compact, inexpensive, reliable and robust.

  • Publication number: 20110282619
    Abstract: A temperature measurement device in combination with a furnace heat exchanger is disclosed and claimed. An instrumented heat tracer sensor is launched into the heat exchanger which records the temperature of the fluid and performance at data points along the length of the heat exchanger. If a spike in the temperature as measured and recorded, since the speed of the heat tracer sensor is known, the location of the temperature increase is known which infers a burn through in the furnace. A three way valve includes a retrieve port, a chamber port, and a launch port. A small sensor control pump and a large heat exchanger flow pump propel the heat tracer sensor through the system. A plastic chamber retains the heat tracer sensor for interrogation and downloading information when the sensor is not in use in the heat exchanger. A control station communicates with the heat tracer sensor and extracts the stored temperature data therefrom.

  • Patent number: 8057095
    Abstract: Device for adapting a temperature probe for a use in a port in a heart-lung machine. An adaptor slip is tapered at an adaptor taper angle less than a port taper angle. The adaptor slip is sized such that the exterior wall of the adaptor slip provides an interference fit with at least a portion of the fluid port. The adaptor slip has an external shoulder abutting the end of the fluid port. The adaptor slip additionally has a sleeve having a closed end having a position with respect to the end of the adapter slip. A probe is configured to be seated in a lumen of the adaptor slip with a proximate end of the probe being proximate to the closed end of said sleeve.

  • Patent number: 8002463
    Abstract: The publication discloses a method for determining a temperature of a substrate, comprising: providing a gas channel that is confined by at least one wall having a certain wall temperature; providing a substrate in said gas channel, proximate to the at least one wall, such that a gap exists between a surface of the substrate and the at least one wall; providing a gas flow with a certain mass flow rate through said gas channel, which gas flow extends at least partially through said gap; determining a pressure drop in the gas flow along the gas channel; and deriving from said pressure drop the temperature of said substrate using a pre-determined relation between the pressure drop along the gas channel, the wall temperature and the temperature of the substrate, at said mass flow rate. Also disclosed is a device for implementing the disclosed method.

  • Publication number: 20110122915
    Abstract: A method for testing heat pipes includes the following steps. A plurality of bar-shaped heat pipes having the same size is provided, and the heat pipes are deformed. The deformed heat pipes are placed in a temperature regulator, such that a temperature of the heat pipes is periodically changed between a first temperature and a second temperature. The heat pipes are then taken out of the temperature regulator. One end of each heat pipe is maintained at a third temperature by a thermostatic device, and a heat pipe temperature difference of two opposite ends of the heat pipe is measured. The heat pipes having the heat pipe temperature difference greater than a standard temperature difference in the heat pipes are marked.
