What is thermal management?

Thermal management is a process that uses various temperature monitoring devices as well as cooling to achieve temperature regulation and control of electronic components. In the current fast growing electric vehicle industry, the need to ensure that the overall battery size remains as compact as ever, to significantly increase the overall range and to reduce charging times, means that there is a higher need for heat dissipation, to prevent thermal runaway, to provide optimal vehicle operating temperatures and to improve overall vehicle performance to meet the current changing market demands.

Trumonytechs thermal management solutions are based on popular demand and provide more efficient thermal management solutions, which are currently used in a wide range of industries: automotive, robotics, marine, etc. They effectively guarantee the longevity of electronic products.

Why is thermal management important?

Let’s take the battery charging and discharging of an electric vehicle as an example. When the battery is charged/running, it generates a lot of heat and when this heat is not dissipated effectively and in a timely manner, it leads to a reduction in the charging and discharging performance of the battery pack, the most intuitive impact on the electric vehicle is a significant reduction in range and an increase in charging time. Most importantly, there is also an irreversible impact on the overall battery life. Thermal management of electric vehicles is therefore an extremely popular area of research at present.

How thermal management works

With the rapid development of thermal management, a variety of methods have been given to end this thermal dilemma. There are three main modes of heat dissipation: conduction, convection and radiation.

Thermal conduction:mainly through direct contact, heat is transferred from the heat generating element to the heat sink element. This is a low cost and efficient conduction mode and is now recognised worldwide as the best thermal management solution. Trumonytechs liquid cooling plate design uses this mode. By conducting heat into the coolant and circulating it into the cooling system for heat dissipation, good cooling is achieved.

Convection: This is a relative flow cooling mode due to the difference in internal temperatures. Generally fluids/gases are able to create convection, a process of heat transfer through their own macroscopic movements.

Radiation: This mode of heat dissipation, which does not depend on any heat dissipation medium, is an active heat dissipation with the help of an increase in the self-generated temperature of the object, and the higher the temperature, the greater the total energy radiated, with relatively poor heat dissipation efficiency.

In general, the current mainstream thermal management cooling mode is still based on heat conduction, like the current luxury car – Tesla’s battery pack is using such a cooling mode.

With regard to the correct choice of thermal conductivity products, we need to pay attention to the following aspects

In order to meet different specific requirements, it is particularly important to choose different thermal management products, or in the case of battery cooling, we need to consider the overall thermal requirements. This is done from two main perspectives: active cooling and passive cooling.

Active cooling: This mode of cooling is achieved mainly through the heat dissipation of the electronic components themselves, where we also offer various thermal interface materials to speed up the overall heat dissipation.

Passive cooling: This is a cooling solution designed for higher heat dissipation requirements, for example the liquid cooling plate of Trumonytechs customers are a perfect example of active cooling.
