[0021] like Figure 1-3 As shown, a heat dissipation chassis with high heat consumption includes a casing 1, a cover plate 2, a power module, an optical power amplifier module 3 and an integrated control circuit box 4. The cover plate 2 can be detachably installed on the casing 1, and the power module, the optical power amplifier module 3 and the integrated control circuit box 4 are all installed in the casing 1. The optical power amplifier module 3 and the integrated control circuit box 4 are powered by the power module. The optical power amplifier module 3 is used to execute the electrical signal of the integrated control circuit box 4. It also includes a TEC cooling plate 5 and a TEC driving box 6. The TEC cooling plate 5 is tightly pressed in the casing 1 through the optical power amplifier module 3. The voltage and current of the TEC cooling plate 5 are controlled by the TEC driving box 6. The TEC driving box 6 and the integrated control circuit box 4 are arranged in parallel on one side of the optical power amplifier module 3.

Since the side of the TEC cooling plate 5 that is in contact with the optical power amplification module 3 is a cold side, and the side that is in contact with the bottom of the casing 1 is a hot side, the cold and hot sides of the TEC cooling plate 5 can be isolated by the heat insulation board 11 to prevent heat from being reversely conducted to the optical power amplification module 3.
