The invention discloses a cold/ heat exchanger graphite core column and a preparation method therefor. The graphite core column is prepared by compounding graphite powder and a binder; The preparation method taking graphite powder as a main starting material sequentially is mainly characterized by comprising the following steps: preparing materials, batching, mixing, drying, performing compression molding, roasting and curing, drilling, performing gum dipping and drying to obtain a graphite core column semi-finished product piece. The preparation method is reasonable in material selection and batching, scientific and exquisite in preparation process and low in preparation cost, and the prepared product has the characteristics of good quality, long service life and the like.
