The invention relates to a thermoelectric refrigeration artificial formation freezer. The thermoelectric refrigeration artificial formation freezer includes a protecting device, a radiator and a solid-state refrigeration device, wherein the protecting device is arranged outside, the radiator is arranged inside, the solid-state refrigeration device is arranged between the protecting device and theradiator and is a semiconductor refrigeration plate, the semiconductor refrigeration plate is provided with a heat absorption end and a heat releasing end, the heat absorption end attaches to the protecting device, the heat releasing end attaches to the radiator, after electrification, the heat absorption end absorbs formation heat, and the heat releasing end takes away the formation heat throughthe radiator; and the semiconductor refrigeration plate controls a circuit, the magnitude of a current, and direction of the solid-state refrigeration device through a control unit. According to the freezer, electrification is refrigeration, a formation can be directly frozen without constructing a freezing station, the project cost and construction period are greatly reduced, the cost is lowered,and the work efficiency is improved; according to the needs of a project, segmenting freezing, directional freezing and forced unfreezing are realized, the refrigeration cost is saved, and the construction period is shortened; and natural water circulation cooling is adopted, and the risk of leakage to pollute the environment is avoided.
