The invention belongs to the technical field of sheath-core composite fibers, and particularly relates to a preparation method of an efficient temperature-adjusting sheath-core composite fiber, and the preparation method comprises the steps of preparation of an aluminum organic ligand, preparation of a sheath layer melt and melt spinning. According to the invention, dicyclohexylmethane diisocyanate and monoethanolamine are subjected to an addition reaction to generate urea bonds which are coordinated with Al < 3 + > to obtain an aluminum organic ligand, Al2O3 which is uniformly distributed is generated in situ in a PA matrix in the melt blending process of the aluminum organic ligand and the PA matrix, the heat conductivity of a skin layer is improved, and the heat conductivity of the skin layer is improved under the combined action with a phase change material in a core layer; the synergistic effect of rapid heat conduction and phase change temperature adjustment is achieved, and efficient temperature adjustment and rapid heat conduction and heat dissipation are completed. The high-efficiency temperature-adjusting sheath-core type composite fiber prepared by the invention can be applied to the fields of home textiles, clothing and the like, and has a better application prospect in mattresses due to good temperature sensing capability.

The invention relates to a temperature control device for temperature control of battery cells (11), comprising a sheet-like main area (2) with a first plane (21) and a second plane (22), a plurality of first support areas (3) on the first plane (21), a plurality of second support areas (4) on the second plane (22), wherein first temperature control channels (5) are constructed between adjacent first support areas (3), wherein second temperature control channels (6) are constructed between adjacent second support areas (4), wherein the main area (2), the first support areas (3) and the second support areas (4) are integrally formed from reversibly deformable material, and wherein the first temperature control channels (5) and the second temperature control channels (6) extend through the main area from a first side (23) of the main area to a second side (24) of the main area (2).
