Summary: | The invention discloses a liquid nitrogen and semiconductor refrigerator, and belongs to the field of refrigeration equipment. The liquid nitrogen and semiconductor refrigerator is characterized in that a liquid nitrogen storage tank is mounted at one end of an existing semiconductor refrigerator, the tank mouth of the liquid nitrogen tank is communicated with the inner cavity of a refrigeration box through a pipeline on which a first electrically operated valve is mounted, an exhaust pipe is mounted at the other end of the refrigeration box, a second electrically operated valve is mounted on the exhaust pipe, a power switch is connected with the first electrically operated valve and the second electrically operated valve, and a temperature control condition setting switch is connected with a temperature sensor and a semiconductor refrigeration device respectively. The liquid nitrogen and semiconductor refrigerator has the advantages of being fast in cooling and high in work efficiency. |
