Please ask us your questions and give us some newsletter ideas
Let us know what you think about this newsletter

TDMG has been in business for over 10 years. When we first started out, I had spent about 12 years in industry with the likes of Pratt & Whitney Canada and Rolls Royce Canada. I had gathered much technical experience at all levels from design to management, but running a business and performing the sales and marketing aspects needed to succeed were not things that I was necessarily exposed to back then. The learning curve was steep and a few

key things became clear very quickly. Our customers want to know that we have the knowledge and the competence to solve their problems quickly and efficiently. Over time we have performed many projects in many industry sectors with great success as witnessed by a high-level of repeat business from those customers.

Today we are introducing our newsletter, which we will issue on a bi-monthly basis in order to share some of the knowledge we have acquired over a 10 year span. The newsletter will cover topics of a technical nature and also some business subjects that we feel could be of interest to our customers.

We will try to make this newsletter an effective means of communication between the reader and ourselves. In order to do this, we encourage you to ask questions and provide ideas about things you would like to see in our newsletter. It will be our pleasure to write about your topics of interest as quickly as possible. Of course, you could always contact us directly if you need more detailed information.

Finally, we also urge you to enter our contest and a chance to win a Sony Video MP3 player.

A Little Bit About TDMG

TDMG is an engineering services provider with key expertise in product development and eng-ineering analysis. We have performed projects in various industrial sectors including telecommuni-cations, medical, aero-space & defense, and consumer markets. We have key specialization in design and cooling of electronic equipment,

where we have performed countless projects. We perform CFD (fluid flow), thermal, and stress & vibration analyses as part of our design process to minimize the technical risks as much as possible before going to prototyping stages. We also have a flow and thermal lab which allows us to do validation testing prior to finalizing our design concepts. Over the

last years we have developed the marked capability to perform building ventilation analysis covering such applications as data center cooling, clean room design, indoor swimming pool design, ect. We urge you to visit our web site for more information at www.tdmginc.com.

Electronics Cooling of VGA Fansink

Electronics cooling has been an area of specialization for TDMG for the past 10 years. The power dissipated by electronic equipment has continuously increased mak-ing thermal considerations ever more important in an industry where time to market is critical and getting the design right first time imperative. This example shows the analysis results for a VGA fansink. The VGA card had 6 components, two of which
dissipated
30 W each.

The design of the fansink had to
consider
height re-
strictions
and had to maintain the 30 W components below a case temperature of 100 C at an ambient temperature of 20 C. The design of the fansink included a low-profile, high performance and long-life fan. The fin layout was optimized to maximize airflow and heat transfer coefficients at the hottest areas. The opt-imization of the fansink was done with CFD (flow and thermal) analysis tools in

order to better understand the influence of each of the parameters.

We have performed countless electronics cooling analyses from large telecommunication systems to sealed enclosures. If you have any questions regarding our capabilities, please visit us at www.tdmginc.com.

Data Center Cooling

Data center cooling is fast becoming a major problem for service providers and operators throughout the world. The heat dissipation capacity of servers is growing rapidly and the existing and new data center infrastructure must cope with these increased heat rejection rates. Since we perform thermal analysis at the server level, we have significant exposure to the issues which arise from improper room cooling and airflow practices. Data center airflow analysis can be done efficiently using similar analysis tools as those used to analyze electronic equipment. The CFD tools we use allow us to obtain an accurate

picture of the airflows and temperature distribution throughout the whole data center. From this infor-mation, it is simple to ident-ify the areas of concern, generally areas where the airflow is poor or exhibiting recirculation. Typically, these areas also exhibit higher air temperatures which have an impact on server performance. The CFD results are highly visual and allow us to quickly identify strategies to fix these poor airflow areas and increase server temperature margin without increasing data center heat rejection rates, and saving the customer a significant amount of capital funds. One example shown here is a data center analysis

where the hot aisle airflow is not extracted effectively and re-circulates back towards the inlet side of the rack. This increases the inlet temperature of the servers located in that specific rack and cause those servers to operate with lower temperature margins. A simple solution was to increase the return airflow so as to extract more hot aisle air and the problem was solved without having to impact the temperature settings of the room.

Canadian SR&ED Tax Incentive Program

Page 3 TDMG Newsletter January 19th, 2010

On a slightly different topic, I would like to discuss the Canadian SR&ED (Scientif-ic Research and Experi-mental Development) tax incentive program. This pro-gram is administered by the Canadian govern-ment and encourages Can-adian businesses of all sizes and in all sectors to conduct R&D in Canada. It is the largest single source of federal and provincial government support for ind-ustrial R&D. The SR&ED program gives claimants cash refunds and/or tax credits for their expendit-ures on eligible R&D work done in Canada. The pro-gram is an absolute

must for any entity conducting eligible R&D work in Canada. TDMG has undertaken a number of R&D programs over time and the benefits of these tax incentives really do go a long way. The actual inc-entives will depend on var-ious parameters and in which province the R&D is conducted (as each pro-vince has it’s own inc-entives), but the rates can be as high as 60% - 70% for small businesses. The average SR&ED refund or tax credit is in the order of 35% of the cost of the R&D work including all business types and sizes. It is therefore important to look

into these incentives and take ad-vantage of them as much as possible. It is possible to get loan approvals and guarantees on the basis of future SR&ED claims. This can be very helpful for funding R&D intensive programs in all industries. For more infor-mation you can go directly to the Canadian govern-ment’s website.
