Heat flow (process) is a leading indicator of temperature (result). By measuring the flow of frictional heat energy generated at the machining point during machining, it is possible to monitor the condition of equipment and cutting tools and to expedite abnormal detection (predictive maintenance). <Examples of Utilizing the Heat Flow Sensor "Energy Flow"> ▼Overview: Measuring the heat flow and temperature caused by frictional heat when machining a torque converter. ▼Background: Until now, monitoring the machining state has relied on temperature sensors and vibration sensors. However, there are limitations in accurately detecting the timing of machining completion and the occurrence of abnormalities in real-time. To prevent unexpected equipment downtime due to cutting tool breakage, it is common to perform maintenance early based on past performance, experience, and the number of processes. ▼Evaluation Results: By installing the heat flow sensor and thermocouple close to the cutting tool, we measured the waveform of the heat flow transmitted to the arm from the frictional heat during machining. It was confirmed that the heat flow sensor could detect "machining completion" faster than the thermocouple. As a means of real-time monitoring of the machining state, the use of a highly sensitive heat flow sensor has been fundamentally validated as effective. *For more details, please download the PDF document or contact us.

Are you having trouble grasping the reality of heat generation and dissipation in thermal design of circuit boards? Since the unit of heat flow is [W/m^2], you can calculate the heat generation [W] by multiplying it by the measurement area. Toyota's heat flow sensor "Energy flow" is highly sensitive and can quickly detect even slight thermal behaviors without missing them, making it useful in the following scenarios. ▼ Overview: By attaching a heat flow sensor and thermocouple to the regulator IC chip mounted on the power supply board, we can compare the thermal environmental behavior due to heat generation associated with the operating voltage of the IC chip. ▼ Evaluation Results: In response to the voltage behavior of the IC chip, heat flow shows better responsiveness than temperature.

The heat flow sensor provided by Toyota Motor Corporation cannot solely convey the thermal insulation performance of buildings and energy-saving items through temperature alone. The heat flow sensor enables the measurement of slight heat flows that are difficult to measure with conventional methods, contributing to more efficient thermal design. It is an ideal product for solving challenges in architecture, construction, and building materials that require data-driven improvements, such as evaluating the performance of insulation and heat shielding materials and identifying thermal losses in buildings. 【Usage Scenarios】 - Performance evaluation of insulation materials: Accurately assess the performance of existing insulation materials and newly developed insulation materials. - Investigation of building heat loss: Identify areas of heat loss in buildings and assist in renovation plans for energy conservation. - Design of new buildings: Conduct heat flow simulations during the design phase to achieve optimal insulation design. - Renovation of existing buildings: Evaluate the insulation performance after renovation and verify its effectiveness. 【Benefits of Implementation】 - Quantitative evaluation of insulation performance: Enables data-driven assessments, resulting in highly reliable outcomes. - Contribution to energy conservation: Identifying and reducing heat loss leads to a decrease in energy costs. - Efficiency in design and construction: Allows for design and construction based on accurate data.

The importance of thermal management is increasing due to the rising risks of high temperatures from the miniaturization and high performance of electronic devices and systems, the impact on the human body from the generalization and common use of electronic devices, and the growing demand for heat stress countermeasures (heatstroke prevention) due to rising average temperatures.
