06/30/08 Elite Thermal Engineering introduces low cost OEM cold plates with dual butterfly mounts

Elite Thermal Engineering, a leading supplier for thermoelectric cooling solutions, released a lower cost OEM thermoelectric cold plate Model OCP-050A, and model DBC-050A that consists of one OCP-050A and two butterfly mounts model BA-01.

Because of the relatively low power nature of all fiber coupled butterfly laser diodes packages, the cooling capacity of ETE's OCP-055 is never fully utilized when used for butterfly mounts. ETE replaced the expensive copper plates and the expensive high end thermoelectric cooling modules with aluminum cold plate and ETE's own lower cost thermoelectric modules, we are able to bring down the cost significantly while still maintaining enough cooling capacity for two of any high power pump lasers on the market.

Butterfly lasers with internal thermoelectric coolers has lower power compare to uncooled packages because of the limit of cooling capacity of internal TECs; Uncooled butterfly lasers provide much higher power that is only limited by the laser diode itself. DBC-050A provides two butterfly mounts for uncooled butterfly lasers, and stabilize the laser with the external TECs. This enables laser developers to use much higher power butterfly lasers while maintaining the temperature of the laser.

Elite is also making our own low cost high performance thermoelectric modules available for sale. We have a complete line of single stage thermoelectric cooling modules and an unique high power high performance dual stage thermoelectric cooling module for demanding applications where high delta T and high cooling capacity are both required.

Most of the multi-stage thermoelectric modules on the market provide either high delta T or high cooling capacity but rarely both. The few that can fit both needs usually are not very efficient. Elite's ETD-8-198 satisfies power, delta T and efficiency.

Thermoelectric coolersare widely used in telecommunication, medical, electrical, CCD camera, and photonics industries. Please visit http://products.elitethermalengineering.com/ for details or email to contact@elitethermalengineering.com, or call 425-770-8147.

12/28/2007 Elite Thermal Engineering introduces 110w thermoelectric cold plate for high power OEM fiber lasers

Elite Thermal Engineering, a leading supplier for laser cooling solutions, introduced model OCP-110, a thermoelectric cold plate for fiber laser OEM or laboratory cooling applications. It provides 110w of cooling capacity when set temperature is same as ambient, and the set temperature can be 48ºC below ambient when heat load is zero. All thermoelectric coolers in the device are environmentally sealed so that OCP-110 can operate reliably at below dew point set temperatures. OCP-110 has a copper cold plate that provides much lower spreading resistance than aluminum.

Since our inception, ETE has been focusing on high performance cooling products that provide the highest cooling capacity per unit volume for photonics industry. The demand for higher power fiber lasers is driving the development of ever-higher power pump lasers. Elite's model OCP-110 is designed to temperature stabilize the most popular fiber coupled laser diodes with mounting patterns that can accommodate lasers made by QPC, LIMO and nLight.

Most of the high power cold plates on the market are impingement cooled for its low thermal resistance; but it requires substantial open space in at least 3 sides of the module and it is hard to integrate them into laser products. ETE's model OCP-110 is side cooled by ducting air through high density heatsinks; but with a high density heatsink and a set of high performance fans, OCP-110 provides more efficient cooling than what's on the market; it provides all the mounting features for directly integrating in a laser product; and it occupies less space than any cold plates on the market at 110w cooling capacity; OCP-110 also provides high quality screw terminal block for ease of connection.

The current carrying capacity of the trace and contacts for laser diode and thermoelectric cooler is rated 6A, making connecting high power 14-pin butterfly pump diodes much easier.

The 14-pin butterfly mounts on the market today are designed for low power diode packages in telecom industry and the connections are limited to few particular brands of diode/TEC controllers. Most end users have to design their own PCB to interface with the 14-pin butterfly package, and it is very inconvenient to test 14-pin butterfly packages. There is no high power 14-pin butterfly mount available on the market today that can carry 6A of current.

ETE's BA-01 makes it possible to conveniently connect/disconnect high power 14-pin butterfly laser packages in minutes either for quick power on inspection, or burn-in, or integrating it into the end products. Users can mount the board flat on the 14-pin butterfly-mounting surface with the provided electrical insulation sheet; once in place, users can mount 14-pin butterfly laser package on the mounting surface. The electrical connection is facilitated with a simple clamp that gently presses the 14-pin butterfly contacts to spring loaded ZIF connectors, all contacts are routed to a 20 pin connector that interfaces with user harness for connecting to diode and thermoelectric drivers. Mating connector information is provided in ETE's BA-01 datasheet, and ETE offers custom cable harnesses to customers as an accessory.

9-18-2006 Power, Feature, Convenience: Cold plate tailored for cooling CS mount laser diodes for laboratory research and OEM products

Elite Thermal Engineering has extended our cold plates product line to OEM applications. The first model OCP-055 is designed specifically for cooling CS mount laser diodes on either an optical bench for laser research or in OEM laser product developments.

The cooling capacity of standard Model OCP-055 exceeds most of the CS mount laser diodes on the market; it can also be optimized to provide higher cooling power with lower temperature difference, or lower cooling power with higher temperature difference with minimal extra cost;

The cold plate provides 2 CS mounting locations: one is at the front for using on optical table where free-space optics can be placed very close to the laser diode; another is located at the center of the cold plate for fiber coupled lasers where the cooling is most effective. The cold plate is electrically isolated from the rest of the module, so it is safe to mount CS mount laser diode directly on it, therefore minimizing thermal resistance from laser junction to cold plate.

The thermoelectric coolers used in OCP series are all environmentally sealed (TECs in all ETE's products are environmentally sealed) for operations below dew point.

ETE's OEM cold plates are also perfect for cooling fiber coupled laser diodes. Model OCP-055 can be easily incorporated into laser products by simply bolting it down to a flat surface in the product.

As a by-product of Model OCP-055, ETE is also offering the ready-to-use forced air-cooled heatsink that is used for OCP-055. The cooling module consists of a heatsink, an air duct and a fan with fan guard, all assembled ready to use. It boasts an ultra low thermal resistance of 0.22ºC/w when the heat source is half the size of the heatsink.

OCP-055 or the fan/sink cooling module has mounting features for 0.5" diameter mounting posts used on optical table; it also provides mounting flanges for mounting it to any flat surface.

ETE also suppliers water cooled cold plates to Photonics community for laser cooling; ETE will be releasing higher power cold plates in the months ahead. To find the latest developments at ETE, or to obtain technical specifications, please visit www.elitethermalengineering.com.

12/15/2005 Elite Thermal Engineering offering laser diode mounting kits

Electrically isolating laser diodes used to be an engineering task. The industrial standard CS mount laser diode package for diode pump lasers is electrically hot; when mounted to laser cooling modules or cold plates, the laser diode must be electrically isolated to protect the laser. In the past, individual end users of laser diodes do all the isolation solutions themselves, and it takes engineering effort to define, design and procure the necessary components. Elite Thermal Engineering is now offering standard diode isolation kits that is in stock or can be provided within 2 weeks if it is out of stock.

The diode mounting kits includes one aluminum nitride plate and 4 nylon shoulder washers for mounting CS mount or equivalent diodes (such as Jenoptik's JOLD packages) on cold plates. Indium foils for thermal interface is also available as an option. Belleville washers for maintaining constant pressure to the thermal interface are also available as another option.

The aluminum nitride plate is .635mm thick, 25mm x 25mm with 4 through holes that match the diode mounting patterns. The nylon shoulder washers fit in the CS mounting holes and are good for M3 screws. The standard kit cost only $ 21.49 each at single quantity.

The aluminum nitride plate offers very high thermal conductivity while providing electrical isolation between the diode and cold plate; the nylon washers isolate the metal screws from the diode package. Elite Thermal Engineering also supplies silicone-free high performance thermal interface materials that can be used between the aluminum nitride plate and diode, and between the cold plate and aluminum nitride plate.

The nylon shoulder washer does tend to creep over time. Therefore Belleville washers or other kind of spring mechanism to maintain positive pressure is recommended. Elite also offers creep resistant PEEK shoulder washers upon request for more demanding applications.

Elite Thermal Engineering is a leading supplier of wide range of cooling solutions for photonics industry including high power high efficiency thermoelectric cold plates, high efficiency compact air conditioners, standard and custom water cooling plates.
