A refrigerator achieving intelligent unfreezing by means of heat pipes. The refrigerator achieves unfreezing in a preset mode by using a single-chip microcomputer control technology and a controlled heat pipe technology. The refrigerator comprises multiple heat-insulation freezing chambers (101-106) and refrigerating chambers (107), wherein temperatures of the freezing chambers (101-106) and the refrigerating chambers (107) are independently controlled. The refrigerating chambers (107) and the freezing chambers (101-106) are connected by using controlled heat pipes (121-126). The heat pipes (121-126) are provided with electromagnetic valves (131-136). A single-chip microcomputer system controls the electromagnetic valves (131-136) to operate or stop. When the heat pipes (121-126) operate, heat transfer media in the heat pipes (121-126) slowly flow to the freezing chambers (101-106) by carrying heat of the refrigerating chambers (107), frozen food is slowly unfrozen within the time preset by a user, the amount of lost juice is reduced when the frozen food is unfrozen, and the nutrition and taste of food are reserved. In addition, because the design of the multiple independent heat-insulation freezing chambers (101-106) is used and cold air of the freezing chambers (101-106) slowly flows to the refrigerating chambers (107), compared with the existing refrigerator, the refrigerator achieving intelligent unfreezing by means of heat pipes saves more electric energy.L'invention concerne un réfrigérateur offrant une décongélation intelligente au moyen de caloducs.
