David Weisman, L.L.C. has introduced its latest Horizontal Conveyorized Gas Fired and Electrically Heated Hot Air Convection Drying and Curing Systems design for customers to dry water off of and/or cure liquid and powder coatings on a wide range of products processed horizontally. The system features great temperature uniformity utilizing bottom up, horizontal or top down air flow and controls, an air recirculation and exhaust system, and a complete energy efficient insulated oven enclosure. The system can be used as a stand-alone complete horizontal conveyorized drying or cure oven system or in conjunction with coating application equipment and incoming and outgoing conveyors.
Heating Block Performance and Utility Compared in New Technical Bulletin
Brinkmann Instruments, Inc., has announced a new Technical Bulletin that describes a series of controlled heating tests comparing the heat-up times and energy consumption of its Radleys Heat-On heating blocks with another leading brand.
Today, scientists are increasingly turning to specially designed aluminum blocks located on stirring hotplates as a safer, cleaner and faster way of heating standard round-bottomed flasks (10 to 5,000 ml). The new Technical Bulletin, TDS02S, demonstrates that not all heating block designs are the same.
In the energy consumption test, comparative experimental data is provided demonstrating that Heat-On uses up to 30 percent less energy to heat up a stirred solution to 100ºC. To compare heat-up performance, comparative tests were performed in 100 ml, 500 ml and 2,000 ml blocks. Experimental data is provided that demonstrates Heat-On heats up to 66 percent faster than the other heating block design.
The report concludes that the lower thermal mass of the Heat-On produces significantly faster heat-up times and faster post-synthesis cool down times. In addition, the Heat-On proprietary well design, which eliminates sticking and cracking of flasks associated with other heating block designs, maximizes the heated surface area further contributing to improved heat-up times. Because of these thermal features Heat-On is more efficient, using less energy to achieve the same results, saving money and reducing the environmental impact.
CPI’s N-Series TeraFrame Network Cabinet Ss Preserving Network Infrastructure Survival
Chatsworth Products, Inc. (CPI), a manufacturer that provides structural support to organize, store and secure IT infrastructure equipment, has released the N-Series TeraFrame Network Cabinet to overcome thermal challenges associated with network switches with side-to-side airflow.
When deploying switches with side-to-side airflow, the N-Series TeraFrame can be equipped with CPI’s Network Switch Exhaust Duct. The exhaust duct removes hot air by isolating and re-directing it out the back of the cabinet and into the hot aisle, minimizing hot air re-circulation and essentially converting side-to-side airflow into a front-to-rear airflow pattern. By running the entire height of the cabinet, one Network Switch Exhaust Duct can support exhaust from up to three network switches and provides freedom to organize and move equipment as needed. Serving as a complete and cost-effective solution for high-density applications, this passive cooling solution allows customers to maximize energy efficiency by including no active components to increase maintenance cost and compromise redundancy, while decreasing total cost of ownership.
The N-Series TeraFrame features advanced cable management solutions that simplify installation and maintenance while providing maximum cable management capacity. The cabinet is designed to accept cables through openings located on the top and bottom of the cabinet, while special T-shaped cable guides and cable management spools align with each RMU, precisely dividing and organizing cables as they enter and exit the rack-mount space. With the ability to manage 48 Cat 6a UTP cables per RMU, the N-Series TeraFrame supplies abundant cabling opportunities.
In order to route and manage large quantities of cable, the N-Series TeraFrame contains Standoff Brackets that support offset doors and side panels, thereby creating added space between the cabinet frame, side panels and doors. Cabinet doors and side panels are easy to remove and provide full access to equipment and cabling, while the ability to route cables around the frame instead of through it offers a simple way to trace cables during moves, add and changes.
Advanced Copper-and-Brass Heat Exchangers Well Suited for Clean Diesel Passenger Vehicles
The availability of new fuels and new exhaust treatment systems has ignited interest in diesel engines for passenger vehicles, SUV and light trucks. According to the International Copper Association, durability and high cooling efficiency make CuproBraze heat exchangers especially well suited to these new small “clean diesel” engine applications.
Diesel engines have long been recognized for their superior fuel efficiency compared to spark ignition engines. Now that ultra-low emission diesel engines have been developed and ultra low-sulfur diesel fuel is widely available, diesel engines will be used in a growing number of vehicle classes.
Cooling systems for new diesel engines must operate at elevated temperatures and pressures. CuproBraze heat exchangers, which are made of brazed copper-and-brass, offer more design options, because copper and brass can withstand higher temperatures than aluminum, and cooling efficiency is greater for copper-and-brass heat exchangers.
Clean diesel engines are available now to meet current international emission requirements, and manufacturers are already considering the modifications that must be made to meet the next generation of standards.
Nuventix Introduces Two New Cooling Modules for LED Thermal Management
Nuventix has released two new LED cooling modules. These two products, utilizing Nuventix’s SynJet technology, provide high reliability, low audible noise and low power consumption cooling technology for two industry standard lighting configurations. Using the SynJet approach allows twice the light output compared to passive LED thermal management designs.
The MR-16 SynJet cooling module was developed by Nuventix for cooling 15 W heat source in an LED lighting application. The cooler is designed to fit the form factor of an MR-16 bulb and provides 300,000 hours L10 life at 60°C.
The PAR-38 is also a SynJet cooling module developed by Nuventix for active cooling of an LED PAR-38 light source. It can be integrated with a wide array of electronic and optical solutions in the PAR-38 form factor. The module cools 35 to 50 watts, provides 300,000 hours L10 life at 60°C and meets PAR-38 form factor while providing near silent acoustics.
“Finally the LED Industry has a cooling technology that is perfectly suited for LED illumination,” said Jim Balthazar, president and CEO, Nuventix. “General lighting LED solutions today are limited by the amount of heat that can be cooled. SynJet technology will allow the LED industry to double its light output in general lighting today, without compromising power efficiency and reliability.”
New Thermal Interface Sleeves for Semiconductor Packages and Thermistors
Fujipoly America has introduced a stock series of 14 sleeve-shaped thermal interface extrusions for semiconductor packages and thermistors. The efficient thermal transfer sleeves are available in three Sarcon formulations and will fit TO-220, TO-3PF and TO-3PL type transistors as well as similar shaped electronic components. In addition to its shape, users can also select from multiple sleeve lengths, inside diameters and material thickness options to best accommodate application requirements.
The flexible sleeves easily slide over and conform to most standard size transistors and electronic components. The snug fit and inherent performance characteristics of the specially-formulated silicone material, allows efficient transfer of unwanted heat from its source to nearby heat sinks. Depending on Sarcon material selection, thermal conductivity across the product line ranges from 1.2 to 2.6 W/m°K with a thermal resistance between .26 and 1.35°Cin2/W.
