Fanless Computers: Still Running Cool!

Fanless Computers: Still running cool!

 

Making a computer with a single fan is good engineering, making them fanless is an art. TANGENT offers fanless computers which are reliable and robust to meet your demanding requirements of ruggedness and performance.

What are major problems with the fans that require us to build fanless computers?

  • Noise: Fans produce noise during normal operation. As the installed system becomes older, the fan becomes nosier. In some applications, noise above a certain level is unacceptable.
  • Maintenance: Fans suck in dirt and clog the filters. This requires frequent cleaning of filters. In certain embedded systems, access to the computer for maintenance is not feasible. Problem of choking of filters exacerbates if the computer in installed in a dusty environment.
  • Failure: A fan is a moving part, with an electric motor. This can fail, resulting in overheating of the computer and eventual system shutdown or even total system failure.

Fanless computer eliminates these problems completely. The computer becomes quieter, becomes more robust and requires less maintenance.

Why are fans required in computers anyway? Well, computers need a lot of processing power that requires high-performance components, especially the CPU. These components generate a lot of heat. If this heat is not removed rapidly and continuously, the system will over-heat and will eventually fail. Fans provide an easy and cheap way to remove this generated heat by blowing air across the hot components and out of the computer casing, keeping the temperature inside the computer within the acceptable limits.

However, the limitations of fans in a dusty environment are significant and in certain application, noise is a major issue. To minimize noise generated by fans and reduce heat generation, various techniques such as; variable and low-speed fans with efficient CPU heat sinks, logic to slow down or shutdown the CPU when not in active use are incorporated. However, the best way to remove the fan-related problems is to remove the fan altogether, replacing it with an alternate heat removal system.

A computer with a good performance is simple to build, but a fanless computer requires a good design. Heat load is carefully calculated and the heat removal system is designed to match the heat load in worst case operating conditions. A system of heatpipes is used to remove the unwanted heat out of the system.

Heatpipes are made of copper or copper alloy, capable of transferring a large amount of heat. Inside the heatpipe there is liquid under low pressure that boils into vapor when it absorbs heat. This vapor then condenses back into liquid at the cooler surfaces of the heatpipe and releases the heat. Heat is taken from the CPU by one end of the heatpipe, and transferred to the other end of the heatpipe in contact with a larger heat sink, which is the Aluminum casing of the computer system. This casing comes in contact with the ambient air and thus dissipates the heat in the air, thereby cooling the system.

TANGENT’s Fanless Rugged Mini PC line is designed with industrial and military grade components and specifications for reliable operation under a demanding environment which require reliable and noiseless operation.

Model Rugged S is specially designed for use in industrial and medical applications. It can be used in mobile medical carts, anesthesia module and display systems. It provides optional ISO ports to meet the needs of Critical Care environments.

Model Rugged S meets rugged design specifications and medical UL60601-1 certification. It comes with built-in watchdog timer for automatic re-start on a non-fatal system fault, optional 4k V Isolation card for patient protection, and an optional TPM for added security.

The Surgical Environment and Noise-free Computers: A Complimentary Pair

 

Tangent’s fanless medical computers contain advanced cooling technology and SSD storage providing noise-free operation. While a silent computer is convenient and desirable, there are specific environments where the noise-free feature is not just a nice commodity, but also a requisite. This article covers the applications of noise-free computers in surgical environments.

 

Operating Rooms: Medical industries are highly dynamic environments filled with technological devices and people. Reducing noise pollution is a continuous common goal that improves the flow of the medical workplace. While silent devices are needed throughout health facilities, none is more important than the operating room, which carries with it the reputation of irrefutable respect- with reason.

Operation outcomes can be the determining factor of life or death. Open-heart surgery, liver transplants, and intestine transplants are just a few high-stake procedures that occur in the OR. Surgeon concentration is of utmost importance as is that of the entire OR team, often comprised of nurses, surgical technicians and anesthesiologists.

While music has proven to increase workflow by setting a nice pace and easing the tension of the surgical environment, distractions must be kept to a minimum. Unnecessary, obtrusive noise has no place in surgical environments and thus is why silent computers make the list of must-haves in them.

Post-Operative Patient Care: While the act of performing surgery is the high-pressured climax of a surgical environment, proper post-operative care is vital to ensure the hard work performed during surgery is successful. Sleep and rest assist to ensure proper post-operative healing. Among the concerns of post-operative patients, sensitivity to light, sound and smells top the list. So while proper functioning computers hold insurmountable value to patient care both in and out of surgery, the ability to do so silently shares equal merit.

Tangent noise-free computers are the perfect pair for the surgical environment delivering silent operation and optimizing sterility. Fanless in design, noise-free computers maintain a sterile environment because the elimination of a fan prevents the circulation of dust particles and airborne debris. The ventless enclosure of our noise-free, fanless computers means zero maintenance ensuring the surgical team can focus on what matters most: patient care.

 

 

The Significance of Anti-Microbial Keyboards and Mice

The Significance of Antimicrobial         Keyboards and Mice

Medical grade keyboards and mice are the gateway to secure, sterile, high-quality healthcare.

Healthcare computers, carts and tablets receive significant credit in the way they have improved healthcare environments producing more efficiency, sterility and better quality service. Nevertheless, as the adage states: a castle can only stand as strong as its foundation. Medical grade keyboards and mice are imperative foundational supporting accessories that must be on par with the other foreground components in order to sustain a superior work environment.

Hands: The gateway to healthcare professionals and their patients. Study after study demonstrates that hands are one of the leading causes in the spread of germs. We teach the importance of clean hands since childhood because if there is anything we have learned from historical plagues to modern day epidemics, sterile hands are paramount to the prevention of spreading disease. Proper hand hygiene is crucial in any healthcare department, let alone workplace. Therefore, the technological tools that hands most come into contact hold insurmountable importance.

While the healthcare industry improves with the incorporation of technological products, in order to maintain the most hygienic and exemplary health environment, medical grade keyboards and mice, the accessories, must meet high quality standards as well.

GATEWAY ACCESSORIES

 Medical grade keyboards and mice are referred to as gateway accessories as they are the channels through which germs and viruses are spread or NOT. At Tangent, all our medical grade keyboards and accompanying mice are SilverShield™ antimicrobial and SealShield ™ waterproof. This translates to fully washable medical grade keyboards and mice. Protect your healthcare workplace to the highest caliber by selecting premium grade healthcare accessories.
