トヨタ自動車 List of Products and Services

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 "Energy flow" thermal flow sensor provided by Toyota Motor Corporation can measure the amount and direction of thermal energy, which is essential for elucidating the mechanisms of temperature change, with high sensitivity and simplicity. <Usage Examples> Quantitative understanding of thermal resistance, which is essential for power IC heat dissipation design. Contributing to the design of electronic circuits, heat sinks, and heat exchangers! *For more details, please download the PDF document or contact us.

In this seminar, we will hear from a current designer at a parts manufacturer about "Key Points for Actual Measurements Using Thermocouples and Heat Flow Sensors," and we will introduce Toyota's high-sensitivity heat flow sensor "Energy Flow." Additionally, as a case study for verifying the discrepancies between actual measurements and analysis, we will present the thermal analysis of the heat flow sensor demonstration kit and its considerations. If you are working on verifying discrepancies between actual measurements and analysis, or if you are engaged in building technologies for thermal design, thermal analysis, and thermal measurements, we encourage you to take this opportunity to watch!

Everyone has experienced knowing the temperature using a thermocouple, right? But is temperature really all we want to know when designing for heat? Temperature is just a result, and often, I feel that lacking information can lead to detours in development when trying to implement effective measures. Have you ever felt that way? By understanding heat flow, we can connect it to effective thermal countermeasures. By the way, what is heat flow? How is it different from temperature? I've organized this information in an easy-to-understand way, so you can ask without hesitation. You can download it for free. Review it quietly and gain an edge!
