HTT is backed by more than 20 years experience in design and manufacturing of heat exchangers. This experience is put to use in the manufacturing of prototype heat exchangers for pre-production evaluation.
Various constructtion types include "tube and fin", "parallel flow", "shell and tube" and "plate-type" heat exchangers.
Typical construction materials include aluminum, copper and stainless steel. Joining methods include aluminum brazing, copper brazing, copper soldering, mechanical expansion and tin diffusion. Heat transfer fluids include refrigerants, various liquids and air.
HTT has expertize in heat exchanger component design, component manufacturing, assembly, fixturing, cleaning, brazing furnace profile settings and quality control.
HTT has designed many unconventional heat exchangers.
For example:
1. Brazed aluminum header and tank design with special flow circuiting resulting in 10% performance improvement
2. 0.8mm OD tube miniature heat exchanger
3. Cylindrical heat exchanger using copper foam as fins
4. Cylindrical heat exchanger using heat pipes and aluminum fins
5. Parallel flow heat exchanger using extruded copper microchannel tubes brazed to serpentine copper fins
HTT is working with numerous academic institutions on the development of new technologies and their associated heat exchangers.
