Abstract: The utility model provides a condensing device for a heat tube for refrigerators, chilling cabinets and other refrigerating systems. The condensing device for the heat tube is directly provided with the original condensing tube in the evaporating end of the heat tube, the condensing tube circulated with high-temperature high-pressure refrigerant is used as the heat source of the evaporating end of the heat tube, an actuating medium inside the heat tube absorbs the heat quantity of the refrigerant to be evaporated, steam rises to the condensing end of the heat tube to release the latent heat of vaporization so as to be condensed, coagulating liquid makes use of the action of the gravity to return the evaporating end of the heat tube, and then a high-speed high-efficiency heat transferring process is formed. Therefore, the utility model improves the refrigeration cycle, raises the condensing effect, reduces the power consumption of the refrigeration systems, lowers the casing temperature of a compressor and protect the motor of the compressor. The utility model has the advantages of small size, high efficiency.
