Referring to fig. 1 to 4, a refrigerator according to a preferred embodiment of the present invention includes: a cabinet 100, a heat exchanger 200, and a refrigeration system.

The cabinet 100 is provided therein with an inner container 110, and the inner container 110 defines a storage chamber 120 therein.

The heat exchanger 200 comprises a plurality of circles of heat exchange tubes 210 arranged on the outer wall of the liner 110, the distance between the heat exchange tubes 210 of two adjacent circles is 20-30 mm (b in fig. 4), the distance between the heat exchange tubes 210 and the opening of the heat exchanger 200 at the opening close to the storage chamber 120 is 40-60 mm (a in fig. 4), and the distance between the heat exchange tubes 210 and the back plate 114 of the liner 110 at the opening of the heat exchanger 200 away from the storage chamber 120 is 15-25 mm (d in fig. 4).

The refrigerating system is provided inside the cabinet 100, and the refrigerating system is in communication with the heat exchange pipe 210, and the refrigerating system is used to provide a refrigerant to the heat exchange pipe 210.

The refrigeration cycle system of the refrigerator of the present embodiment generally includes a compressor, a condenser, a dry filter, a capillary tube, and the like, which are connected to each other by a refrigerant pipe. Specifically, the low-temperature low-pressure vapor refrigerant from the heat exchanger 200 enters the compressor, and is compressed by the compressor to become the high-temperature high-pressure superheated vapor refrigerant. The high-temperature high-pressure superheated vapor refrigerant flows out of the compressor, enters the condenser, is condensed under the isobaric condition, and becomes a high-pressure supercooled liquid refrigerant, and in the process, the condenser radiates heat to the surrounding environment medium. The high-pressure supercooled liquid refrigerant flows out of the condenser, enters the capillary tube, is subjected to isenthalpic throttling by the capillary tube, is changed into a low-temperature low-pressure vapor refrigerant, and flows into the heat exchanger 200. As the low temperature, low pressure vapor refrigerant passes through the heat exchanger 200, it absorbs heat to the surrounding ambient medium, thereby refrigerating the refrigeration chamber. When the heat exchanger 200 is arranged on the cavity wall of the refrigeration cavity, the direct-cooling refrigerator is obtained; when the heat exchanger 200 is arranged in the air duct of the refrigerator, the refrigerator is an air-cooled refrigerator. The above-mentioned structural arrangement and the operation principle about refrigerator refrigeration cycle system are prior art, and this application is not repeated.

The utility model discloses refrigerator, including box 100, heat exchanger 200 and refrigerating system, through setting up heat exchange tube 210 around establishing on the outer wall of inner bag 110, the wall that heat exchange tube 210 and inner bag 110 contacted is the plane, reduces the gap between heat exchange tube 210 and the inner bag 110, improves the refrigeration effect, and the foaming layer can not crowd in addition between heat exchange tube 210 and the inner bag 110 outer wall yet, places the influence refrigeration effect.

In addition, the interval of the heat exchange tubes 210 is set within the range of 20-30 mm, the distance between the heat exchange tube 210 at the opening of the heat exchanger 200 close to the storage chamber 120 and the opening is 40-60 mm, and the distance between the heat exchange tube 210 at the opening of the heat exchanger 200 away from the storage chamber 120 and the back plate 114 of the inner container 110 is 15-25 mm, so that cold air transmitted to the inner container 110 is ensured to ensure the refrigeration effect, and the user experience is improved.

In the prior art, the distance between the heat exchange pipe 210 of the heat exchanger 200 near the opening of the storage chamber 120 and the opening is less than 40 mm, and the top of the storage chamber 120 is prone to frost formation. This is because the storage chamber 120 has a larger amount of hot air above the opening and a higher exchange rate of cold and hot air with the outside of the refrigerator. After many times of tests, if the distance is less than 40 mm, frosting is easy to occur, and the use of a user is affected, and when the distance is more than 60 mm, the temperature at the opening cannot meet the requirement on low-temperature performance.

When the interval between the heat exchange pipes 210 is greater than 30 mm, the power consumption per 12 hours may be greater than 1kw.h, and in the range of 20-30 mm, the power consumption per 12 hours may be reduced. When the distance is less than 20 mm, the temperature in the storage chamber 120 is too low, and a small amount of water vapor in the storage chamber 120 is also solidified into frost, so that the amount of frost in the storage chamber 120 is large, and the use of the refrigerator is affected. When the distance is greater than 30 mm, the cooling efficiency of the storage chamber 120 is decreased, and the power consumption is increased.

Wherein, table 1 shows energy consumption experimental data, the ambient temperature is 25 ℃, and the power consumption of the temperature stabilization section is taken after refrigeration is carried out for 48 hours.
