ECU Vents

An ECU, or Electronic Control Unit, is a critical electronic device in vehicles such as automobiles and other sophisticated mechanical systems. ECU vents are apertures on the ECU housing that are primarily utilized to circulate air between the interior of the ECU and the outside environment.

​

Its main functions are heat dissipation and moisture avoidance. The ECU contains a high number of electronic components, such as integrated circuits and transistors, which generate heat while in operation. Under high-load conditions, the ECU chip's temperature can reach 70-90℃ or greater. If the heat is not released in a timely manner, it will degrade component performance, shorten its life, and potentially cause failure. Vents let cold air to enter and heated air to exit, keeping the ECU's internal temperature within an acceptable range. At the same time, vents assist prevent condensation of water vapor induced by temperature variations inside the ECU, keep the interior dry, and protect electronic components from moisture.
 

1. Prevent overheating: During operation, the ECU creates heat, which vents can help dissipate, preventing the ECU from overheating and protecting the ECU's electrical components from harm.
2. Prevent condensation and moisture: In a humid environment, condensation can form inside the ECU, resulting in short circuits or other electrical issues. Vents help to prevent condensation by allowing moisture to escape from the interior of the ECU while inhibiting the entry of external dust, dirt, and liquid pollutants.
3. Pressure balance: During vehicle operation, the pressure inside the ECU must be balanced owing to variations in external air pressure. Vents can control the pressure difference between the interior and outside of the ECU, preventing sealing issues caused by pressure imbalance.
4. Improve ECU life: Proper ventilation can reduce thermal and mechanical stress caused by temperature and humidity variations in the ECU, increasing its service life.
5. Reduce failure rate: Proper ventilation can reduce environmental-related ECU failures while also improving vehicle reliability and safety.
6. Maintain ECU performance: Vents help to keep the ECU at a reasonable operating temperature, ensuring that it accurately performs control functions.

ECU Vents effectively prevent rain, hail, snow, dust, dirt and debris from entering the module. They also rapidly and continuously respond to differential pressure, rapidly balance overpressure and vacuum, thereby protecting seal integrity, extending service life, and preventing water and dirt from entering the module.

1. Vents/Grids: Vents or grid structures are typically designed on the ECU housing or mounting point to allow air movement and dissipate heat. These openings are typically small and are intended to keep air circulating while preventing dust and moisture from entering the system.
2. Active Cooling System: In some high-performance autos or electrical products, the ECU may include an active cooling system, such a fan. The fan continuously blasts air to remove extra heat.
3. Heat Sinks and Thermally Conductive Materials: In addition to vents, some ECUs have heat sinks that leverage metal's strong thermal conductivity to dissipate heat. The use of heat sinks in conjunction with vents can further improve heat dissipation efficiency.
4. Sealing and Protection Design: Dustproof, waterproof, and corrosion-resistant vents are common for ECUs used in severe settings like off-road vehicles and heavy machinery. This ensures long-term effectiveness and endurance.

What's the secret to SRVENT™ being so effective?

Our waterproof breathable products benefit from the patented SRVENT™ breathable membrane technology.The microporous structure allows air and gas to pass through freely, balancing the pressure and allowing water to diffuse before problems arise.Because the holes in the breathable film are 20, 000 times smaller than water droplets, they prevent liquid and fine dust and particles from entering.

It has been verified on site all over the world

Hundreds of millions of SRVENT™ ECU vents have been incorporated into electrical and electronic modules on automotive platforms around the world because of their advantages:

• A fast and continuous balance of overpressure and vacuum due to environmental changes, whether the vehicle is in a running or stopped state.

• Effectively diffuses water and solves the condensation problem.

• Reliably prevents water, hazardous vehicle fluids and particles from entering the housing, preventing damage to electronic components.

• Provide a complete set of waterproof and breathable solutions, with embedded, glue-back and welded construction, suitable for any electrical or electronic module.
