The compressor ^ 疋 constitutes the role of the body 1 in the cleaning of the refrigerant in the U cycle. Li::··2, with a compressed cold device (not shown) condensed... The two-U compressed refrigerant is condensing and reducing pressure. The refrigerant of '°H' is provided above the compressor 11 by a capillary tube (not shown). The first heat sink type cooler 13 (hereinafter referred to as "first cooler 13"), the second heat sink tube cooler u (hereinafter referred to as "second cooler 14"), the cooling fan 15, and the radiation The heater 16, the heater cover 17, and the drain pan 18 having the drain hole 19 are chilled to the return port 20 and the refrigerating chamber return port 21 is provided in the cooler chamber 12. The first cooler 13 is composed of a heat transfer pipe 133 and a plurality of flat fins Ub penetrating and fixed to the heat transfer pipe 13a. The second cooler "as with the first cooler 13" is composed of a heat transfer pipe 143 and a plurality of flat fins 14b penetrating and fixed to the heat transfer pipe 14a. The second cooler 14 is as shown in Fig. 3 The i-th cooler 13 is small in size and disposed on the upstream side of the air flow of the first cooler 13. Further, the heat transfer member 14a of the second cooler 14 is subjected to a surface treatment with high water slidability. For example, The material having the new hydrophobicity or hydrophilicity is applied to the surface of the second cooler 14. This is to reduce the amount of frost and moisture retained during defrosting. 201205018 The first and second coolers 13 and 14 constitute the body 1 One element of the cold cycle having the same tongue is connected. The coolers 丨3 and 丨4 evaporate the refrigerant decompressed by the above capillary tube, and cool the temple edge by the heat absorption during the evaporation. The fan 15 is disposed above the first and second coolers 13 and 14, and sucks the cold air cooled by the first and second coolers 13 and 14 and sends them to the respective chambers of the main body 1. The radiant heater 16 is disposed in the chamber. The lower part of the cooler 13 is attached to the first and second cooling benefits 13, 14 The frost is melted. The heater cover ιγ is disposed between the first cooler 13 and the radiant heater 丨6, and the heater cover 7 is for removing the first and second coolers 13, 14 by the radiant heater 16. The water dropped in the frost is not directly dripped. The drain pan 8 is disposed at the bottom of the cold chamber 12 for receiving the drain dripping from the i-th and second coolers 13, 14. The drain hole 19 provided at the bottom of the drain pan 8 is discharged. The freezer compartment return port 20 is an air path between the freezing compartment 4 and the cooler compartment 12, and the refrigerating compartment return port 21 is between the refrigerating compartment 2 and the cooler compartment 12. When the cooling fan 15 is in operation, cold air flows from the freezer compartment 4 toward the cooler to 12, and when the cooling fan 15 is stopped, the ambient temperature balance may occur from the cooler compartment 丨2 Convection to the freezer compartment 4. In the freezer-refrigerator as described above, the cooling air cooled by the first and second coolers 13 and 14 is sent to the respective chambers by the cooling fan during the cooling operation. Into the cooler chamber I. By the circulation of the cold air, the crucible is arranged in the first cooling In addition, the amount of frost attached to the second cold portion 14 on the upstream side of the air flow is smaller than that of the first cooler 13 disposed on the downstream side of the second cooler 1 *. In this manner, since the second cooler 14 is disposed on the upstream side of the air flow from the first cooler 201205018, the amount of frost adhering to the second cooler 14 is larger than that of the first cooler 13. Therefore, The flat fins 13b of the first cooler 13 are not blocked by frost, and the heat exchange efficiency of the airflow can be suppressed from decreasing. Further, the second cooler 14 is added during the cooling operation in which the frost is not attached. Since the heat exchange efficiency of the airflow is reduced, the heat exchange amount of the entire first and second coolers 13 and 14 is increased, and the effect of reducing the power consumption of the refrigerator and the refrigerator as a whole is increased. Furthermore, the heat sink 14b of the second cooler is formed in a flat shape, so that it can be reduced in cost compared with the conventional use of the spiral heat sink. The second embodiment is a second embodiment of the present invention. The cross-sectional view of the cooler chamber of the freezer is enlarged, and the same reference numerals are given to the same portions as those of the embodiment of the 帛i. In the second embodiment, the 散热2 fin-and-tube cooler 14 (hereinafter referred to as As shown in FIG. 4, the "second cooler 14" is smaller than the second heat sink tube cooler m (hereinafter referred to as "i-th cooler 13"), and is disposed more than the first cooler 13 To the upstream side of the air flow. Further, the mounting angle of the second cooler 14 is inclined in the range of 45 to 90 degrees with respect to the flat fin of the second cooler 13 . The angle of the second cooler "matches the direction of the cold air flowing into the cooler chamber from the cold chamber return port 20 and the refrigerating chamber return port 21. The gas is longer than the embodiment of the second cooler 14. Therefore, therefore, the inflow The time during which the cold flat fins 14b in the cooler chamber 接触2 are in contact with each other is improved more than the first one, and the enthalpy exchange effect of the second cooler 14 is improved, i?-?, and the Wuhuan rate is attached to the second cooler 14 In addition, the amount of the heat-transfer tube 14a is increased, and the cold-storage product of the 201205018 is provided to the market. The third embodiment is a cooler of the refrigerator according to the third embodiment of the present invention. The same reference numerals are given to the same portions as the second embodiment. u In the third embodiment, the fins 2 are cooled by the stomach 14 (hereinafter referred to as "the second cooler 14". As shown in Fig. 5, it is smaller than the first tube-cooler 13 (hereinafter referred to as "the third cooler"), and is disposed upstream of the air flow of the first cooler 13 side. In addition, the attachment angle of the second cooler 14 is a flat heat dissipation with respect to the first = the cooler 13 from the freezer compartment return port "and the refrigerating compartment return port 21 to the cold air flowing into the cooler t! The sheet 13b is inclined so as to be at a degree of 45 degrees to degree, and the phenomenon that the frost adhered to the second cooler 14 is easily grown in the range of the collision between the cold air and the flat front edge, and the flat plate shape is enlarged: the front edge area of the sheet ub... The 乍== octagonal shape of the shape of the flat fin ub is promoted to promote the octagonal shape of the second cooler 14 to be attached to the octagonal shape of the second cooler 14 The market provides a cold-cutting method with excellent energy-saving performance: the shape of the flat fin 14 of the second cooler 14 is externally 14b, but is not limited thereto.
