Abstract
Disclosed is a dynamic wall heat exchange device based on piezoelectric excitation, comprising a base support. A sidewall of the base support is provided with a strip-shaped opening, and a low-temperature heat source runner is arranged in the strip-shaped opening. The base support is further provided with a high-temperature heat source runner. The high-temperature heat source runner comprises a main pipe erected on the base support. The main pipe is sleeved with a heat exchange sleeve, and corrugated pipes are connected to the main pipe in series. The low-temperature heat source runner also penetrates through the heat exchange sleeve. The base support is provided with a plurality of elastic cantilever arms, the lower ends of each of the elastic cantilever arms is provided with an inertial mass block, and a piezoelectric stack is arranged between the elastic cantilever arm and the inertial mass block.
