Embodiments provide a multi-junction thermocouple comprising a first junction and a second junction positioned to measure temperature at substantially the same portion of a substrate. A controller may detect failures in the first junction, the second junction, a first wire pair extending from the first junction, or a second wire pair extending from the second junction. The controller desirably responds to a detected failure of the first junction or first wire pair by selecting the second junction and second wire pair. Conversely, the controller desirably responds to a detected failure of the second junction or second wire pair by selecting the first junction and first wire pair. Systems taught herein may permit accurate and substantially uninterrupted temperature measurement despite failure of a junction or wire pair in a thermocouple.

The present invention provides a thermoelectric cooling apparatus for cooling an electronic device such as a CPU, or a computer chip. The apparatus cools the electronic device by two stages. In the first stage, a heat absorbing block collects the heat produced by the electronic device and the apparatus pre-cools the electronic device by dissipating a portion of the collected heat in a distant location through a front heat conductive device and a front radiator. Thereby the heat of the electronic device is reduced to a degree that a TEC can efficiently handle. In the second stage, a TEC of the apparatus dissipate the residual of the heat produced by the electronic device through at least a back heat pipe and a back radiator.

Differential thermopile heat flux transducer
InactiveUS6278051B1Thermoelectric device with peltier/seeback effectThermoelectric device manufacture/treatmentHeat flowThermopile
A thin sensor for heat flux and temperature, designed for adhesive attachment to a surface, is manufactured on a flexible insulated metallic substrate. The sensor exhibits a combination of high sensitivity for heat flux and low resistance to the flow of heat. These characteristics enable it to measure heat flux at surface boundaries with improved accuracy over conventional heat flux transducers because the temperature drop produced by the sensor is very small. The response by the sensor to radiation, convection and conduction are equal. As such, the sensor can be calibrated in one mode of heat transfer and used for measurement in other modes. The high sensitivity of the sensor makes it ideal for measuring heat flow through insulating materials, and well adapted to instrumenting heat flow in buildings, detecting fires at an early stage, or remotely measuring the temperature of string and web products in industrial processing.
