AI Technical Summary
Existing temperature control structures are difficult to effectively isolate ambient temperature interference, resulting in unstable wavelengths of single-frequency gratings, which affects communication quality and system stability. At the same time, their heat dissipation efficiency is low, making it difficult to meet high-precision requirements.
The design employs a combination of a temperature-controlled base, a temperature-controlled cover, a heat dissipation base, and TEC components. The first TEC component directly controls the temperature of the single-frequency grating packaging module, while the second TEC component heats or cools the temperature-controlled base. Combined with heat dissipation fins, this achieves efficient heat dissipation and creates a stable temperature environment.
It effectively isolates ambient temperature interference, improves the wavelength stability of single-frequency grating packaging modules, enhances heat dissipation efficiency, ensures high-precision temperature control requirements, and improves communication quality and system stability.
