HHL SUB-MOUNTS

HHL header is special box-like high heat load (HHL) package. This is the largest industrial standard header available. HHL headers are typical as a standard packaging solution for solid-state laser pumping in medical and industrial application areas like: materials processing, medical and dental therapeutics, graphic arts and others. HHL base material can be various. It can be Kovar, cold rolled steel (CRS), CuW or CuMo coated with nickel and gold. HHL header has usual 9 pins on one-side. HHL header surface open for mounting is about 24.0×24.0 mm2, which is enough for a wide range of TECs. RMT Ltd offers different solutions with single-stage and multistage TECs as well as complex design with two TECs are available.


Sub-Assembly Overview

Standard Sub-Assemblies Solutions

This is a list of standard, most common solutions with TECs mounted on HHL headers with 9 pins. The complete list of possible solutions is wider. HHL header is suitable for any thermoelectric cooler with hot side dimensions up to 24.0×24.0 mm2. Please, contact RMT Ltd in case if specific solution on HHL is required.

TEC performance parameters are specified at standard conditions (+27°C, vacuum). The datasheet for each sub-assembly contains also the additional data, specified at +50°C, N2. Please, download the datasheet for detailed info. The affect from HHL Cu(20%)-W(80%) base thermal resistance (Rt) is included into specified performance values. HHL sub-assembly is required to be attached to an appropriate heatsink to spread the heat, pumped from LD (or another source) and thermoelectric cooler. Heatsink thermal resistance may affect on performance, and is required to be as low as possible. Heatsink thermal resistance influence is not included into specified performance data.

You may use TEC Select Assistant to find other thermoelectric coolers suitable for HHL header. Press the On-Line Assistant link and specify hot side dimensions as 24.0×24.0 mm2 as a main search criteria. The cooling capacity of TEC is recommended to be as at least 2 times higher than expected heat load in the application. For example, for 2W estimated heat load, please, specify TEC Qmax as at least 4W in the search field. The assistant will specify all thermoelectric coolers compatible for mounting onto HHL package. The datasheets for not listed HHL sub-assemblies are available by request.

Headers Available

It's a typical drawing of HHL header. The header dimensions may vary to a small extent, depending on the manufacturer.


 


Note: RMT Ltd provides the sub-assemblies - thermoelectric coolers, mounted on HHL headers. The company doesn’t manufacture the headers or provide headers separately. The mounting service is also available on Customer’s headers upon request.
