Application development for mid-temperature discrete sensing unit using thermoelectric green device

Project period : FY2015-FY2016

FY2015 Annual Report

(I) Use case promotion:

(A) Automotive sensing

The purpose of this project is to implement a clean thermal battery device is the assistive technology of the engine optimal control to the exhaust pipe. In this project FY, we performed as follows: (1) confirmation of exhaust conditions of the driving cycle in gasoline vehicles; (2) the amount of power generation and specs of the thermoelectric modules: (3) Implementation structure to the exhaust pipe of the thermoelectric module. To determine the steady-state evaluation condition from the exhaust data obtained was to confirm generation output of the generic thermoelectric modules that condition.

(B) Biomass boiler sensing

The purpose of this project is to implement a clean thermal battery device is the assistive technology of the Biomass boiler optimal control to obtain stable and flexible boiler operation. In this project FY, we performed as follows: (1) Measurement of distribution of temperature for Biomass boiler, where we did analysis for the distribution of temperature in gas flow channel, and decide mounting positions for the device. (2) build a test boiler and test the test boiler with the power generation device.

(II) Elemental device/system formation technologies

(A) Thermoelectric power generation device

Evaluation of the prototype device with elements of the silicide has been performed. Then, the output power of the device was higher than the target value. The draft of the specification of the themoelectric device has been considered in the project. We'll proceed with studies of drafts of the specification.

(B) Thermal connection and impedance matching

Thermal interface material (TIM) is the effective material for obtaining the stable thermal contact between heat source/drain and thermal-to-electric module, we examined TIM materials for lower temperature side during this year. A Polyurethane based TIM provided nice thermal contact with the value of thermal resistant. For the heat flow analysis, a simulation software for thermal fluid was newly installed, and calculated one thermoelectric power generation chip.

(III) Precise measurement and standardization

(A) Measurement method utilization

We designed and fabricated novel measurement tool for the commercially available thermoelectric modules. The thermoelectric modules were measured under several conditions (impressed pressure, ambient, thermal contact materials). As the results of the evaluation, we selected the following measurement conditions for database of thermoelectric modules, the impressed pressure to the device was 1MPa, the measurement ambient was vacuum, the thermal contact material was carbon sheet.

(B) Precise evaluation and common measurement method

Two different types of commercial thermoelectric devices consisting of half heusler alloy and silicides were tested, and also conducted the survey for testing methodology for thermoelectric devices by visiting NIST (USA), NPL (UK) and Fraunhofer Institute IPM (GER) . The data was analyzed and discussed in the committee in this project, and became a base for standardization activities in the corresponding project.
