2 H SERIES OMPT IR-TO-IR HET EHNERS SPEIL ONFIURTIONS H FLUSH-MOUNT When you need reliable and efficient cooling for high-heat loads in enclosed electronic equipment or demanding outdoor applications, the avid H Series air-to-air heat exchanger delivers. H Series heat exchangers use two-phase heat pipe technology to create an efficient and cost-effective heat transfer system. This maintenance-free cooling solution is also designed to ensure your enclosures remain contaminant free, and maintain NEM 4 and NEM 12 (IP66 and IP55) integrity. Heat pipe heat exchangers are an easily adaptable technology for custom applications. Whether mounted externally, partially recessed or captured within duct work, the heat pipe heat exchanger is a reliable and highly efficient heat transfer mechanism that can maintain NEM 4 and NEM 12 enclosure integrity. You can also take advantage of the capillary action of heat pipes to design systems that work in any orientation, including against gravity, or systems for extremely space-constrained applications. H Series heat pipes can be manufactured to function in freeze-thaw conditions. esign flexibility and application versatility are integral to the H concept. Multiple packaging options are available for various applications, and product design can easily be scaled to fit any thermal capacity. esigned to provide a thermal performance of 12W/, this unit uses the flexibility of heat pipe heat exchanger technology to accommodate different mounting configurations.

3 Hi SERIES LOW-PROFILE IR-TO-IR HET EHNERS 53 SERIES LIQUI-TO-IR HET EHNERS For high-heat transfer performance with indoor and outdoor electronic enclosures, rely on avid H Series. These versatile heat exchangers give you compact size and significantly improved heat transfer performance, even at high-heat loads, through double-sided impingement cooling technology. The Hi Series heat exchanger can dissipate twice the heat load of most conventional heat exchanger technologies of similar size, so you can have both higher performance and lower fabrication costs. When heat dissipation requirements are too great for natural or forced-air convection systems, avid 53 Series high-pressure liquid-to-air heat exchanger is the solution for you. Liquid-to-air heat exchangers give you effective closed-loop cooling in high-performance thermal management applications. Standard units are available with 2, 4 or 6 fans, and custom optional features such as alarms and temperature controls are also available.

6 STINLESS STEEL HET EHNERS ESSORIES N OPTIONS Many industries, such as food-and-beverage and pharmaceutical, have chosen stainless steel as the standard material choice for their applications. With its corrosion-resistant properties, stainless steel can be steam cleaned, providing a hygienic, antibacterial surface which gives it a modern and attractive appearance. ecause of these attributes, stainless steel is often the best value option when considering the total life of your application. VRILE SPEE ONTROLLERS EMI/RFI SKETS N FILTERS Intelligent Fan ontrollers neoprene gasket that maintains the NEM rating of the enclosure is supplied with each standard heat exchanger. EMI/RFI gaskets and filters are available for custom designs only when requested. avid can also conduct testing to confirm performance. avid Stainless Steel Heat Exchangers Product Offering For NEM 4 environments including corrosion-resistant applications Type 34 or 316 stainless steel housings Strategically placed thermocouples monitor internal thermal conditions (heat generated by electronics and sun Set the fan speed to provide "just enough" cooling at the lowest possible noise levels and save energy in the process). FN FILURE LRMS Fan failure alarms are available on select heat exchanger models. These units monitor fan speed and trigger an alarm if there is a fan speed reduction or motor failure. n intelligent fan controller provides the ability to manually set and change fan speeds as the system is tested and tuned. This allows the manufacturer to accurately validate how the system performs and simulate the conditions to collect and report on the data needed by site planners.

7 FREQUENTLY SKE QUESTIONS Q o you provide customer drawings or models to help integrate heat exchangers into the design? ustomer prints and dummy models, in STEP or IES format, are available to help you allot space inside the enclosure and/ or define the mounting requirements. Q. What is the fan life in a heat exchanger? With the variety of operating conditions available, it is impossible to predict fan lifespan for all applications. Fan supplier life data is available upon request. Thermostat and/or fan speed controllers can reduce runtime and/or RPMs to extend fan life. Q. Where are heat exchangers typically mounted in an enclosure? They can be mounted vertically or horizontally on the inside or outside of the enclosure. Mounting toward the top of the enclosure is typical, because that is often where the hottest air accumulates. Hi Series heat exchangers should not be mounted on top of the enclosure unless it is covered. Otherwise, the core of the Hican fill with rain water, which would block external air flow and prevent heat exchange. Q. How are they installed? Installing the heat exchanger onto studs is recommended. Nuts and bolts can also be used, but sealing washers should be used externally for NEM 4 applications to eliminate the possibility of water intrusion into the enclosure. Install units at least 6 from any obstructions that may impede airflow. For security reasons, install the heat exchanger from inside the enclosure to prevent external access to the mounting hardware. However, installation from outside the enclosure is sometimes required to simplify maintenance. Q. re gasket and/or mounting hardware included? gasket that maintains the NEM rating of the enclosure is supplied with each standard heat exchanger. Follow the mounting methods recommended above. Installation on studs is preferred. ecause avid does not know the specific mounting method to be used, mounting hardware is not provided. Q. an the H Series air-to-air heat exchangers be mounted in an upside down position? No, the hot side of the heat pipe heat exchanger must be level with or below the cold side. The heat pipe core is designed to work with gravity for greater heat removal efficiency. For this reason, heat pipe heat exchangers cannot be mounted to the bottom of the enclosure. Q. an liquid-to-air heat exchangers be mounted at the top of an enclosure? No, it is not recommended. Should a leak develop, water could drip on sensitive electronics. lso, if the liquid temperature is below the dew point of the air inside the enclosure, condensation can collect and drip from the heat exchanger onto the electronics. Q. What about outdoor use of liquid-to-air heat exchangers? non-freezing glycol/water mixture should be specified when using units in freezing temperatures. Q. an altitude affect performance? Yes, the higher the elevation, the lower the air density, which will reduce performance. Q. What type of routine maintenance is required? Maintenance depends on heat exchanger type and mounting location. The Hi style of heat exchangers requires very little maintenance except for fan replacement (as previously discussed). n annual check for cobwebs, insect nests and other types of blockages can maximize heat exchanger performance. H-style heat exchangers have smaller gaps between fins, requiring more frequent checks for blockages when used outdoors or in dirty environments. With the heat exchanger turned off, foreign matter can be cleared from fins with compressed air or a hose with water. Keep air or water flow parallel to the relatively thin fins and pressure low enough to prevent damage and deformation. 14
