Description

Technical Field

[0001] The utility model relates to the technical field of thermoelectric cores, and more specifically to a protective device for thermoelectric cores. Background Art

[0002] Thermoelectric cells are components that generate heat when powered. When in use, their exterior needs to be protected.

[0003] After searching, the existing patent number CN204348761U is a composite thermoelectric chip, including cold and hot end ceramic plates, N and P type electric couples, guide bars, and a metal layer is set on the outer surface of the substrate of the hot end ceramic plate. Since the metal layer is added to the outer surface of the TEC hot end ceramic substrate, the connection between the TEC hot end substrate and the hot end heat exchanger can be welded, so that the contact thermal resistance between the two is much smaller than the original surface bonding method by mechanical force compression. Especially for high power and high heat flux density working conditions, the heat dissipation effect of the new structure TEC hot end is significantly improved, so that the TEC can achieve high power refrigeration.

[0004] The common thermoelectric core protection device has a relatively simple structure. The thermoelectric core is coated with a plate on the outside, but its pressure and impact resistance are poor, which affects its service life. Therefore, we propose a protection device for thermoelectric cores to solve the above problems. Utility Model Content
