Abstract

See full text

A Stirling cooler structure having multiple cooling modules includes at least one power unit, a pipeline, a plurality of Stirling cooling modules, and at least one piezoresistive unit. The power unit includes a cylinder and a piston. The pipeline is connected to the cylinder. The Stirling cooling modules each include a pipe and a passive displacer. The passive displacer is reciprocally, movably disposed in the pipe to partition the pipe into a cold end and a hot end. The hot end is connected to the pipeline. The piston is driven by an electric motor for a compressed air to flow through the pipeline to the hot end and then flow to the cold end through the passive displacer, such that the cold end absorbs ambient heat. The piezoresistive unit is selectively disposed between the Stirling cooling modules and the cylinder.
