What is Thermal Management?

Thermal Management is a technique to constrain the temperature of a system employing methods based on heat transfer and thermodynamics.

The phrase Thermal Management is hence explaining all practicable means and methods like various types of heat transfer, including conduction, convection, and radiation, to enhance or reduce the temperature and/or the temperature distribution of a particularized system.

This system is a component, geometry, or area with pre-defined edges. Defining the system indicates producing a physical model, which is as detailed as necessary and as simplified as possible, to permit the analytical approach of the thermodynamic problems. The system can be pretty complicated (area consisting of multiple components, diverse materials, merging solids, liquids, and gases, large or miniature, stable "steady-state" or switching over time "transient"). Furthermore, the ambient conditions play a pretty crucial role.

The edges are representing the ability of the system for mass and energy transfer. The meaning of the content will determine the ability of the system to utilize these transfers to modify the system's temperature and temperature distribution by collecting and releasing mass and energy. In complicated systems, it can be necessary to determine "sub-systems" to explain the interaction between major parts of the main system. After the system is described with its borders and contents, critical parameters are fixed like the mass, geometry, and material parameters.

Temperature is the principal state variable of a system, which determines the energy level of the system. Each system has a given capacity to store or dissipate energy. This ability is termed the "heat capacity" of the system, and it can be determined by the mass and also the specific heat capacity of present materials in the system. When energy is conveyed into the system or is generated by an internal source in the system, the system energy level can grow. Greater energy levels of the materials in the system are making the temperature of these materials increase. The specific heat capacity describes the connection between absorbed or decayed energy and the temperature variation.

When the system specs do not fulfill the system demands under the ambient conditions, this deviation should be specified in quality and quantity. Thermal Management concepts employ various strategies to solve specific gaps between requirements and specs. Basic concepts are heating and cooling, heat removing, cycling, and temperature homogenization. Principles applied for these concepts include enhancing heat transfer (by means of surface expansion, material selection, using forced convection, and also design the system to meet evaporation and condensation), selective heat transfer, thermal insulation, and active cooling with thermoelectric.

What is Thermal Management Applications?

What is Thermal Management Applications

The thermal management of an electronic device performs a crucial role in various applications, from medical instruments to automotive controls to telecom devices. Thermal management directly affects a product's performance, including its reliability, accuracy, and lifespan. As technology progress, so does the requirement for higher power consumption, making thermal management more essential than ever. Here we describe some most important applications of thermal management in various fields.

Medical: The application of electronics in the medical business is appreciated by all of us. Even when we confront today’s appearance of electronics in the medical field with only a decade ago, we see a distinguished dependence on electronics to present care and diagnosis. As a result, healthcare specialists depend on the reliability and accuracy of these instruments to provide decent care to their patients. Bio-medical equipment has similar electronics cooling elements, but their reliability may directly affect someone’s well-being with the unique sensitivity. Moreover, like with any other electronics, they are demanded to operate at a higher response rate without failure. As a result, their thermal management is of predominant concern.

Embedded Computing Applications: Excess heat can create difficulties for several embedded computing applications. Thermal management provided by component makers may be unavailable or inadequate. Thus, engineering must take the time and care to set up thermal tests to obtain the most effective cooling system.

Aerospace: Avionics and other aerospace electronics contain some of the world’s most exceptional technologies. Advanced electronics are often associated with more power consumption, and as a result, higher heat production demands serious attention to the thermal management challenges they create.

Automotive: As automobiles proceed to use advanced electronics, heat dissipation is growing rapidly, and thermal management is developing more of a driving force than ever since. The current computing sophistication in most vehicles challenges some of the complex telecom and data center equipment on the market, with a principal challenge of uncontrolled ambient conditions that uniquely meet automotive electronics. With the increase of electronics application in various parts of vehicle advancement, effective thermal analyses must be undertaken to avoid potential heat-related issues that may endanger a vehicle's operation.

What is Thermal Management Importance?

There are a few distinct reasons why thermal management should be considered a crucial part of the design process. As a basic idea, it should be noted that we do not want any of our devices to get so hot so that their lives are diminishing.

The working temperature of an electronic device is directly correlated to its reliability, lifespan, and performance. Devices that operate closer to their maximum allowable temperature have a lower service time frame before they deteriorate. Hot silicon devices do not function as well. Anyone who has performed some intense computer or console games knows that you are going to encounter lag if the computer gets too hot. For gamers, lag can solely indicate a life-or-death state in the game. But devices that support safety and life in medical, automotive, aerospace, and military applications, really can be a matter of life and death. So, keep in mind: safety is not optional.

Touch temperature is another pivotal point in the user experience. Devices that are too heated to handle easily can pose risks to the end-user as well. You had presumably fried yourself a bit when you were turning off a hot lamp. Or you have picked up a smartphone or a laptop that has been operating too long and noticed it is super hot. Hot products can cause a high risk of harming your end-user, which is not a good factor for company prominence or product sales at all.
