This invention provides an electronic card cooling device with a multi-dimensional extended structure. Through a collaborative design of a two-dimensional planar array and a three-dimensional cascade, it significantly increases the effective working volume of the electronic card material within a limited space, thus laying the structural foundation for improved cooling capacity. Based on this, the cooperation between the magnetic drive unit and the mechanical linkage module enables stable and rapid reciprocating motion of the electronic card components between the hot and cold ends. Furthermore, the timing delay control of the circuit control system further ensures precise synchronization between the temperature change cycle of the electronic card effect and the mechanical motion cycle, allowing the electronic card material to absorb heat when in contact with the hot end and release heat when in contact with the cold end, avoiding energy loss. This invention, by simultaneously expanding the number of electronic card materials and components in two-dimensional and three-dimensional space, achieves a spatial dimension multiplication of cooling capacity, maximizing the cooling effect in space-constrained scenarios, and providing an effective solution to overcome the bottlenecks of existing electronic card cooling technologies.
