Gain Insight on Reliable Solutions for Demanding Environments
Electronics cooling for critical applications is often needed in the demanding environments present in aerospace and military applications. A cooler not only has to be effective but it needs to be reliable as well. TECA products are made in the USA and utilize thermoelectric technology. Known for its reliability and low maintenance requirements, thermoelectric cooling serves cooling applications in the toughest conditions. Learn more about thermoelectric technology and see examples of where it is best utilized.

00:00:01 [Music] welcome to electronics protection in aerospace and defense where I hope you will gain insight into the contexts in which thermoelectric technology can benefit you photographed here is a 14 year old teka model a HP 1200 X air conditioner it was in service for over 120,000 hours before requiring a thorough cleaning after removal of
00:00:27 debris from the hot side this model could cool reliably once again when reliability is not negotiable when performance over cost is the order of the day thermoelectric cooling technology is likely the best solution thermoelectric air conditioners protect electronics in all environments cooling up to a half ton is possible with a single thermoelectric cooler
00:00:53 thermoelectric cooling technology is uniquely positioned on the thermal management family tree thermoelectric enclosure coolers are more compact and technologically advantageous than simpler solutions like fan trees when compared to vapour cycle cooling there's less maintenance lower cost of ownership and less vibration simply put in mission-critical
00:01:23 applications reliability is king thermoelectric cooling is a reliable long-lasting technology by its very nature making it an ideal and sometimes the only candidate for certain projects how does thermoelectric cooling technology work in a thermoelectric module heat transfer is achieved by applying electricity too dissimilar semiconductor materials extra electrons
00:01:52 in n-type semiconductor material and a shortage of electrons in p-type semiconductor material move heat energy from the cold side to the hot side the main parts of a thermoelectric system are a cold Junction a heat sink and a low voltage DC power source in a nutshell thermoelectric cooling is a solid-state method of heat transfer sometimes called the Peltier effect a
00:02:17 thermoelectric cooler has no moving parts other than its fans it uses no freon coolant or compressor making it safe for the environment due to its solid-state nature it is known to have a long service life [Music] for example individual thermoelectric modules at room temperature are rated with a mean time between failure of
00:02:40 200,000 to 300,000 hours at an elevated ambient of 80 degrees C 100,000 hours mean time between failure has been calculated who uses thermoelectric cooling what kind of applications benefit the most from its use typically engineers and end-users who are dealing with the most trying conditions turn to thermoelectric cooling to protect their enclosures electronics enclosures in
00:03:09 tough environments meet any number of challenges humidity high ambient temperatures salt spray blowing sand ambient dirt and debris to name a few [Music] protecting sensitive electronics and sealing them off from contact with dangerous ambient environments is imperative in military aerospace medical laboratory and industrial applications
00:03:40 to illustrate this imagine a military vehicle carrying communications equipment into the field it will likely be exposed to shock vibration and harsh elements such as blowing sand in our example a thermoelectric air conditioner such as the tacca model a HP 1200 X M is suitable to exposure to all these conditions utilizing components design techniques and military-grade fans on
00:04:14 both the hot side and the cold side this type of air conditioner will maintain its robust integrity during the trip once in the field the end user will be able to set up the communications equipment turn on the thermoelectric air-conditioner to provide protective thermal management and repeat this process again and again [Music]
00:04:41 what other applications might benefit from thermoelectric cooling hard-to-access areas such as an industrial plant crane-mounted electronics and enclosures along rail lines are a few examples consider the urgency of each application as well as its surrounding environmental conditions [Music]
