IP 65 rated enclosure with heat dissipation

In summary: Almost everyone has some sort of computer screen carried around on their person. Add Bluetooth and make an app. No touchscreen necessary.

Hi there!

Is there any ip65 rated enclosure material with electronic components inside but with no holes/cutouts that can act as a heat sink without overheating while the product is operating?

Enclosure will need to be wall-mounted outdoors, it could be made out of die-cast aluminium which acts as a heat sink but the problem is that it will overheat so it may have to require some silicone cover to prevent people from burning their hands when touching it during hot temperatures.

Is there another way of solving this issues without changing material, or is glass reinforced plastic enclosure with aluminium heat sink inside the way to go? Cheers

If heat sink is getting too hot you don't want to make the problem worse by insulating it . If you have plenty of room just make the heat sink bigger or fix the existing heat sink to another larger one .

Otherwise put it in a well vented stand off enclosure . Basically put a bird cage around it .

Putting it into a well-vented stand off enclosure might be better as making the heat sink bigger increases the cost and weight of the product. On the other hand, the top lid of the aluminium enclosure might still need to be opened if the product is not functionally properly and the installer wants to check inside to fix it.

How can an installer or electrician open the enclosure with burning his/her hands? Would a silicone door handle work?

You may have to bite the bullet and just buy a MUCH bigger enclosure (an IP65 enclosure indicates you need to protect from the environment and high pressure water). If you can't ventilate as suggested, you may need to provide air for cooling (there are ways to inject air and exhaust the heat via venting). Without more information, we are simply speculating on your problem.

Basically I'm trying to design a solar inverter which contains printed circuit board with electronic components and electromagnetic interference filter inside and LED touch screen display that is going to go on the top lid of the enclosure. If I use a die-cast aluminium enclosure then I do avoid having to put a heat sink inside the enclosure as the aluminium enclosure can acts as a heat sink. However, since the aluminium get very hot it means that that anyone who touches the touchscreen will burn their hands. The alternative is to use a glass reinforced plastic enclosure and add a heat sink inside the enclosure, but this adds weight and costs.

The surface temp is defined by the power dissipation of the enclosure so will be the same regardless of it's material.
As others have mentioned, you need to increase size to reduce temp.

1. What does "IP 65 rated" mean in terms of an enclosure?

"IP" stands for "Ingress Protection" and the number following it refers to the level of protection against solid objects and liquids. In the case of an IP 65 rated enclosure, the "6" indicates that it is completely dust-tight, and the "5" means it is protected against low-pressure water jets from any direction.

2. How does an IP 65 rated enclosure provide heat dissipation?

IP 65 rated enclosures are designed to have ventilation holes or vents to allow for air flow. This, combined with the use of heat-dissipating materials, helps to dissipate any heat buildup within the enclosure.

3. What materials are typically used for IP 65 rated enclosures with heat dissipation?

Common materials used for these types of enclosures include aluminum, stainless steel, and polycarbonate. These materials are known for their durability and heat-dissipating properties.

4. What types of environments are IP 65 rated enclosures with heat dissipation suitable for?

IP 65 rated enclosures with heat dissipation are suitable for a wide range of environments, including outdoor settings, industrial areas, and areas with high levels of dust or moisture. They are also commonly used in electronic and electrical applications where heat dissipation is critical.

5. Are there any additional features that can be added to an IP 65 rated enclosure with heat dissipation?

Yes, there are several additional features that can be added to an IP 65 rated enclosure with heat dissipation, including fans, louvers, and filters. These features can help to further enhance heat dissipation and protect the contents of the enclosure from dust and debris.
