The semiconductor refrigeration chip 1 can achieve the maximization of refrigeration efficiency under the condition that the material is unchanged and the current is unchanged. Furthermore, the refrigeration unit 2 of the present invention is provided with local turbulence creating structures for creating local turbulence in the liquid flow path, which greatly promotes the heat convection movement of the liquid and enhances the temperature diffusion so that the temperature of the drinking liquid (such as water, beverage or juice) in the storage container 5 is relatively low.
More preferably, the refrigeration transferring part 4 includes a cold guiding plate 41 and fin fins 42 protruding from the cold guiding plate and serving as the local turbulence forming structure, and a passage for the drinking liquid to pass through is formed between the fin fins 42.
