Semiconductor refrigeration refrigerator

Abstract

The invention provides a semiconductor refrigeration refrigerator. The semiconductor refrigeration refrigerator comprises a liner, a wind way cover plate and a semiconductor refrigeration device, wherein a storage cabinet is limited in the liner; a mounting opening is formed in the middle of the back wall of the liner; the wind way cover plate is arranged at the inner side of the back wall of the liner; a wind way is formed between the wind way cover plate and the back wall of the liner; a wind return port is formed in the wind way cover plate opposite to the mounting opening; wind outlets are respectively formed in the upper part and the lower part of the wind way cover plate; one part of the semiconductor refrigeration device penetrates through the mounting opening to extend into the wind way; and a cooling fan arranged on the semiconductor refrigeration device is arranged behind the wind return port for sucking an airflow in the storage cabinet into the wind way. The wind way is formed between the wind way cover plate and the back wall of the liner of the semiconductor refrigeration refrigerator, and upper and lower two air circulations are formed in the storage cabinet by using the cooling fan, so that the internal temperature of the storage cabinet is balanced, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a semiconductor refrigeration refrigerator. Background technique [0002] Semiconductor refrigeration refrigerators, also known as thermoelectric refrigerators. It utilizes semiconductor refrigerating sheet to achieve cooling through high-efficiency annular double-layer heat pipe heat dissipation and conduction technology and automatic variable pressure and variable flow control technology. It does not need refrigeration fluid and mechanical moving parts, and solves the application problems of traditional mechanical refrigeration refrigerators such as medium pollution and mechanical vibration. . [0003] However, semiconductor refrigeration refrigerators need to effectively conduct the temperature of the cold end of the semiconductor refrigeration sheet to the storage room of the refrigerator. In the prior art, heat sinks are generally used as the cold source. The cooling structure ha...
