Thermal Components

TMT specializes in thermal control - anything from ejecting waste heat to maintaining and transferring thermal ideals for parts and systems.

Flexible Thermal Straps

TMT has developed flexible thermal straps - reliable, flexible, metallic thermal straps that facilitate the transfer of heat while retaining flexibility between thermal components. Thermal straps are constructed of copper (braid or foil) or aluminum (foil only) and can be produced to meet customer requirements. Flexible thermal straps are used in a wide variety of applications to provide a passive means of transporting heat from source to thermal sink. 

Standard Straps

In order to give customers quick access to these straps at an affordable cost, TMT has established a limited set of “standard” flexible thermal straps that can be purchased at will to facilitate faster delivery. Contact TMT to learn more about standard configuration orders.

 
Have a Question?

TMT welcomes the opportunity to answer your questions or address any concerns you may have. We look forward to hearing from you today!

Custom Straps

In addition, custom straps of various thermal conductance, operating temperature, size, and end connections can also be designed, fabricated, and tested for customers. Just contact TMT today to get the process started. 

TMT engineers have designed and fabricated a variety of thermal straps, from the very small (0.6 W/K) to the very large (~50 cm long 90 K chamber heat spreaders at 1.5 W/K). 


Flexible thermal straps are configurable to almost any desired shape and end-block configuration. Please fill out this form and email to TMT at information@tmt-ipe.com to begin work on your design specification.

Thermal straps are relatively simple to implement, but require careful thought. In the design of any thermal strap, the engineer will determine which parameters are important to the success of the project. Typical considerations include:

Thermal Switches
 

Thermal switches provide a method to disconnect or reconnect the conductive thermal path between components. This can provide high isolation or increased thermal conductance and provide increased protection for cooling systems.

'Passive' Thermal Switches

'Passive' cryogenic thermal switches can provide thermal isolation for systems. If a cryocooler fails or is switched off, the cold side of the switch will warm up, causing the switch to open, thus thermally isolating the failed cooler from the operating system. Other popular uses can include disconnecting from a thermal radiator during long eclipse events.

Other switch designs require a normally closed condition, but for TMT's thermal switch, heat is required drive the differential thermal expansion to open the switch. If one cooler fails, the switch opens and goes from high thermal conductance to high thermal resistance autonomously and without electronics. The switch is actuated by temperature differences and runs automatically without the 'closed' condition required by other switches. 

All of our thermal switches are custom designed for your particular use case and require knowledge of users needs for isolation and conductance.

Contact TMT today to start your thermal switch design.

Thermal Isolators
 

When operational surfaces experience extremes in thermal output, thermal isolation is a cost-effective solution for supporting components with minimal impact to the overall cryogenic system. This critical factor can quickly make all the difference in your system. 

TMT is experienced in a variety of thermal isolation techniques and can help select an appropriate solution for your thermal application.
