Problems solved by technology
The refrigerating evaporator of the existing direct-cooling refrigerator basically adopts a plate-tube or wire-tube design, so that when the existing direct-cooling refrigerator is used, the surface of the refrigerating evaporator will be in contact with the inside of the freezing compartment. The hot and humid air is in direct contact, and because the density of the hot air is lower than that of the cold air, a large amount of hot and humid air will gather in the front and upper part of the freezer compartment, resulting in obvious local frosting.
With the increase of the service cycle, the temperature in the freezer room will easily rise due to the thick frost layer, which will not only cause the cooling performance of the direct cooling refrigerator to decline, but also cause high power consumption, seriously affecting the User's normal use

The present invention provides a direct cooling refrigerator, which comprises an inner tank and an evaporating tube group arranged on the inner tank, and the evaporating tube group at least includes a first evaporating tube, a second evaporating tube and a The energy-saving element in contact with the tube, at least one of the first evaporator tube and the second evaporator tube is a bile-wrapped type, and the heat transfer coefficient of the energy-saving element is the same as that of the first evaporator tube and the second evaporator tube. The heat transfer coefficients of the tubes are all different, so that the direct cooling refrigerator of the present invention can not only effectively control the frosting part, but also play the role of energy saving.
Description
technical field [0001] The invention relates to a direct cooling refrigerator, in particular to an energy-saving direct cooling refrigerator. Background technique [0002] A refrigerator is a device that uses the cooling effect of the refrigerant in the refrigeration circuit during compression, condensation, expansion, and evaporation to maintain the interior of the refrigerator at a low temperature, thereby preserving food. [0003] The direct-cooling refrigerator maintains the temperature in the box at a low temperature by continuously driving the refrigeration circuit. The refrigerating evaporator of the existing direct-cooling refrigerator basically adopts a plate-tube or wire-tube design, so that when the existing direct-cooling refrigerator is used, the surface of the refrigerating evaporator will be in contact with the inside of the freezing compartment. The hot and humid air is in direct contact, and because the density of hot air is lower than that of cold air, a l...
