Providing reliable and integrated embedded computing solutions and understanding and fulfilling customers’ needs has always been one of Moxa’s strong points. By incorporating a vertical integration chain from product design to engineering to manufacturing, Moxa is able to offer a wide temperature embedded computer solution that is compact and guaranteed to operate reliably in harsh industrial environments.

Moxa differentiates itself from other IPC companies by providing a unique product design and conducting several chamber testing phases to provide a reliable and cost-effective solution. But how did Moxa design a computer that is both small and high performance and guaranteed to work reliably in a -40 to 85°C operating temperature? Read on to learn the secrets behind the design of Moxa’s new V2101 embedded computers.
 
Why use V2101 as an example?
 
The V2101 is the best product to demonstrate the combination of compact size, high performance, and wide temperature. At just 5.9 x 4.9 x 1.9 inches and supporting an Atom platform, the V2101 provides high-speed serial communications, network redundancy, and multiple storage expansion options. It also operates continuously and consistently in a temperature range of -40 to 85°C, which makes it a perfect fit for harsh industrial environments. In the long run, you’ll save both time and money by incorporating the V2101 in your industrial networking applications.
 
How does Moxa ensure that computers such as the V2101 reduce maintenance and repair costs by providing greater system reliability, longer life, and higher quality?
 

One of the major challenges faced by IPC manufacturers is to provide a fanless computer that meets industrial standards and works well in wide temperatures and harsh environments. Throughout the entire product design phase, Moxa has made system reliability a top priority, and Moxa’s specialized thermal engineers have carefully chosen components that meet the wide temperature requirements for the hardware and layout. The board and chipset layout are ideally arranged to optimize the thermal conductivity properties of the board.

To ensure product reliability and quality, Moxa’s thermal engineers use a natural-convection thermal chamber (NCC) in the testing phase to simulate a windless environment that is comparable to an actual industrial application. Other manufacturers may test their products with forced-convection thermal chambers (FCC), which are known to provide a poor approximation of actual environmental conditions for industrial applications.

  Forced Convection Chamber (FCC):  
     
  Uses close to no airflow with less than 0.5 ms condition. The results from these tests are usually unreliable since the environments they simulate are generally inconsistent with actual environmental conditions found in industrial applications.  
  Natural Convection Chamber (NCC):  
     
  Allows engineers to establish a windless environment that more closely resembles actual industrial application settings. Results from these tests are more reliable since static airflow is used to simulate real industrial environments.  
 
But how does compact size,
high performance, and wide temperature combine to produce a viable product?		  
   

From the beginning of the product design phase, Moxa used tried and tested thermal technology principles to design this product and make it suitable for industrial applications that operate in harsh environments. More often than not, industrial computers are required to be fanless and cableless, making the design even more challenging and increasing production costs. One of the key factors is thermal design.

  
 
What is thermal technology and why is a good thermal design important?  
   

A good thermal design is important to ensure an embedded computer’s quality and reliability, and is especially important for computers with a small form factor. Thermal technology and form factor are intricately related, and Moxa’s engineers use thermal technology to translate higher energy density in a small space and offer small and fast-cooling computing systems.

Moxa’s V2101 embedded computers have been thoroughly tested for reliable performance by subjecting them to worst case scenario testing. The computer is first heated for eight hours, and is then subjected to four hours of fluctuating high temperatures that sometimes exceed the target temperature, and are then finally exposed to one hour of operation at the target high temperature. This rigorous testing ensures a high level of system reliability. For more information about V2101 embedded computers, click here.
