摘要

A thermal battery having an enclosure including a fluid inlet and outlet. Between the inlet and outlet are tubes of encapsulated phase-change material. The tubes are arranged parallel to each other, and include radial spacers for spacing the tubes apart, such that the radial spacers of each of any two given contiguous tubes are longitudinally and radially offset from one another so as to allow fluid to circulate.
