Thermoelectric Cooling for TACAN (Tactical Air Navigation) System

TACAN (Tactical Air Navigation) System uses Thermoelectric Cooling:

Thermoelectric Cooling for TACAN (Tactical Air Navigation) System     thermoelectric panel coolers

TACAN is a radio system which can provide aircrew with navigation and bearing information. A market leader in military solutions uses TECA Model AHP-1800XHC as a standard component to provide cooling to their mobile TACAN system. AHP-1800XHC is well designed for this type of application. For reliable performance under harsh conditions, we use military-grade sealed fans and components on the hot side (external to enclosure). The AHP-1800XHC heats and cools as needed without maintenance or repair down time. This has been crucial for our customer, who markets their mobile TACAN system as self-sufficient.

TECA has been designing and manufacturing for harsh military environments for decades. Contact us to discuss your our solutions for NEMA-4X and Shock & Vibration.

CORROSIVE ENVIRONMENT

The AHP-1802XPHC-2 met the customers need in an application where other similar products could not function due to extreme corrosive environment.

The TECA design team in a short notice was able to provide a solution based on a standard AHP-1800X thermoelectric air conditioner.

MILITARY

Military Application:

The 2.4 Meter Mobile SATCOM Tactical Terminal (MSTT) is a lightweight, stand alone, trailer-mounted tri-band SATCOM terminal available to support worldwide, quick deployment satellite communications through military and commercial satellites.

It also uses a customized version of the solid state air conditioner AHP-1801X. It was designed and qualified for worldwide operation in tactical military environments.

Intermodal Control Cooling

Intermodal Control Cooling:

Intermodal systems are increasingly upgrading to automate their processes. Where there is automation, there is a need for control cooling. TECA supports automation by protecting crucial electronics in control cabinets. This minimizes process time and maximizes productivity.

In this example, heat-sensitive electronics are installed in truck processing terminals. TECA Model AHP-1800XEHC offers heat and cool modes and keeps the equipment within safe and operable temperatures.

AERONAUTICS

A leading military and aeronautics contractor needed a cooling solution for an enclosure which would be on a high altitude vessel. The system would be exposed to high winds and ambient elements present in the altitude.

Working with the customer; TECA sales and engineering team designed a cooling solution with specific intake and exhaust characteristics along with custom paint and finish process that could withstand the conditions it will be exposed to.

PORTABLE SECURITY EQUIPMENT

Portable Security Equipment:

Site monitor and security equipment for oil fields and transfer stations needed more security. A portable enclosure housing cameras, WI-FI access, antennas and a Mac Mini computer inside leveraging the Mac platform to provide virtually instant access, hi speed, via “Wild Blue”. The system will be like a watchdog that they can strap on wherever they need the monitoring.

With a slight modification an AHP-1200XE thermoelectric cooler provided the best solution while keeping the NEMA-4 rating of the enclosure.

RUGGEDIZED MILITARY APPLICATION

Ruggedized Military Application:

Sometimes it just takes a long time to get to the heart of a problem. AHP-1200X “quick quote” for two thermoelectric air conditioners came into our sales team. It was responded to and followed up. The application was reviewed, a quote was made and an order placed.

Only after did we learn that the hard requirements they were looking for were:

  1. Dual adjustable temperature control (heat and cool)
  2.  28 VDC operation and
  3. Military environment.

Fortunately the selections within TECA’s enclosure air conditioner family are large. The military Contractor borrowed a unit from TECA’s loaner stock and based on that success, placed an order. It was then that we found a problem.

It seems that the application was to cool some sensitive electronics out on a 200 meter DC input which caused droop in the input which in turn caused a ringing in the circuits. The new digital monitors being used were susceptible while the older tube monitors had no issue.

Working with the customer it was determined that by changing the controller to a ruggedized PWM controller all problems were solved.

MILITARY COMMUNICATIONS

Military Communications:

A branch of the US military had a need for cooling a small enclosure containing a critical voice communication system. The shipboard system had to be resistant to salt water corrosion as well as pass stringent shock and vibration testing.

Modifications to TECAs AHP-300X solid air conditioner allowed the unit to meet specializing and air flow requirements and pass these tests. The challenge was to overcome the small available space both inside and outside the enclosure. The heat sinks were turned so that the heat rejection air flow and internal cold side air flow moved in different directions.

This unit is a prime example of how flexible Team TECA is when customer needs require customization of standard products.

AVIONICS MAINTENANCE

Avionics Maintenance:

The task was to create a portable cooling system for diagnostic equipment to allow troubleshooting of avionics systems while still installed. Troubleshooting and diagnosing avionics problems is hard enough on the bench.

To save valuable time, technicians would rather get it done while the electronics are still in the aircraft. Also, under harsh environments, it is difficult to keep cutting edge electronics functioning the way they should. When it came to the type of portable cooling for the diagnostic equipment required for these jobs; a navy contractor came to TECA for the solution.

We helped design and build the solution shown in its prototype form around the portable enclosure. TECA completed the project on a tight schedule, which called for teamwork and attention to detail.

MILITARY TROOP TRANSPORT

It was 1994 and a military contractor came to TECA with a problem. The existing Freon based refrigerators used in troop transport galleys had a MTBF measured in months.

They had recognized the potential of thermoelectrics and contracted with a vendor to design and build refrigerators for them.  The problem came when the original vendor’s product failed to live up to its potential. TECA was approached and given only several months to design, build and test three prototype refrigerators for the first new galley.

Less than three months later with test data in his hands and three refrigerators in the back of his truck a TECA rep delivered the goods. Over twenty years later the military and it’s allies around the world are still flying these same refrigerators and ordering more.
