Effective Cooling Solutions

Thermaco has an enviable reputation for supplying OEM customers with effective cooling solutions in the form of Fans & Blowers, Heat Sinks and Cooling Modules.

Thermal Interface Material (otherwise known as TIM) is used to form an effective thermal bridge between a heat sink and heat source (invariably IC’s, LED Arrays or Power Semi-conductors).

The requirement to increase the power output of certain products, such as in LED Lighting, within a similar or even smaller, form factor, can adversely affect a product’s reliability. The use of an effective TIM helps improve the thermal transfer from component to heat sink, and so reduce the potential for failure.

Some customers can be forgiven for thinking the cost of TIM outweighs the benefit of its incorporation into their assembly, so Thermaco has sourced, and can provide, the following products, at competitive prices:

* Thermally Conductive Paste (also known as Thermal Grease or Gap Filler); packaged in tubs, tubes or syringes

* Thermal Adhesive; supplied in sachets and used to bond IC’s to heat sinks where there are no other mounting method is available

* Thermally Conductive Pads; supplied in sheets, rolls, or die cut to customer specific size and shape

* Double sided thermal tape; designed to aid in the assembly process

* Thermal Phase Change Material; changes from a solid at room temperature to a liquid at operating temperature, increasing the level of contact between the heat source and heat sink mating surfaces

All the above products are offered with various heat transfer value options.

Anyone using TIM, interested in receiving a quotation, should provide details of the product that they currently use, including volumes, packaging type and specification. Alternatively, the existing manufacture’s name and product reference number should be sufficient for Thermaco to establish and propose a suitable alternative.

TUV Certification Now Obtained On The Sunon ECO Ventilation Series

Thermaco are pleased to announce TUV Certification now obtained on the Sunon ECO Ventilation series of bathroom ceiling ventilation fans.

Ideal for new build and loft conversions, but can also be retro-fitted in installations with a suitable roof/void.

The BVE120 models provide 33 litres of airflow per second, consuming only 4.5 Watts of energy.

This airflow is more than twice the volume required to meet current Building Regulations for bathrooms and toilets, and is installed in conjunction with 100mm/4inch piping.

Due to the use of a forward curved impeller, the BVE120 is also very quiet, less than 29dB(A), as well as being extremely energy efficient.

The same BVE120 models are also suitable for use in Utility rooms, where the building Regulations require in excess of 30 litres per second.

We also have a larger BVE250, which can move 70 litres of air per second, suitable for positioning anywhere in kitchen ceilings, meaning a cooker hood extractor is not required.

The BVE250 is also installed in conjunction with 100mm/4inch piping.

All models include a dust filter which is remove-able for cleaning. Some models incorporate an LED light, available in both cool or warm light options.

Distributors seeking to retail this series should contact sales@thermaco.co.uk.

Free Energy- A Reality!

As part of their recently introduced Peltier device range, Thermaco limited also have available Thermo-Electric Generators (TEG’s). These devices can be used to convert existing differential temperatures in a given system, to actually generate electrical energy.

Normally you would use Peltier devices to create a temperature differential across 2 adjacent surfaces by using electrical energy. Typical example a picnic cool box which plugs into the car cigarette lighter. However, with a TEG the reverse is possible, using a temperature differential which already exists within a system it is possible to generate some electrical energy “for free” which can be utilised or could potentially be stored for future use in a battery.

Applications already utilising this technology include https://en.wikipedia.org/wiki/Thermoelectric_generator but clearly many more exist waiting for Design Engineers to unlock this potential.

Effect of Dust & Lint Build-up on Cooling Fan and Heat Sink Performance

This document pertains to HP Notebook PC’s, but is relevant to any Electronic Equipment incorporating ‘Forced Air Cooling’.
The electrical components in a PC generate heat, and fans inside the PC help move the air to keep the components cooled to normal operating temperatures. Inadequate cooling can cause excess heat which forces the fan to run constantly, can damage components, and limit the speed of the CPU. All of these problems with high power and high heat will cause applications to work less efficiently than normal.

The sound of the fan running all the time may the first clue that your PC is not running as efficiently as possible and that you may have a problem with accumulated dust clogging air vents or heat sinks fins.

Dust and lint on heat generating components and fans

Notebook PC’s have vents in the bottom and sides to allow air to flow through the case. If these vents become clogged, or heat generating parts become covered with dust, the fan cannot cool the components properly. Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder. If there is dust in the vents, you should clean the computer by blowing out the dust from around the fan and heat sink. This will prevent dust from accumulating as shown below.
