Referring to fig. 1, fig. 1 is a schematic cross section of a refrigerator 1 according to an embodiment of the present invention. The invention provides a refrigerator 1, wherein the refrigerator 1 is suitable for being used singly and embedded in a cabinet. In general, the refrigerator 1 may include a cabinet 10 and a door 60.

The cabinet 10 may include a housing 11 and at least one liner 13, the housing 11 being located at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1. The plurality of inner containers 13 are wrapped by the outer case 11, and a space between the plurality of inner containers 13 and the outer case 11 is filled with a heat insulating material (forming a heat insulating layer 12) to reduce heat dissipation of the inner containers 13 to the outside. Each liner 13 may define a forwardly open storage space 16, and the storage spaces 16 may be configured as a refrigerator compartment, freezer compartment, temperature change compartment, etc., with the number and function of the particular storage spaces 16 being configurable according to pre-determined requirements.

The number of the door bodies 60 can be the same as that of the inner containers 13, namely, each storage compartment of the inner container 13 which is opened forwards can be opened and closed by the corresponding door body 60. The door 60 is movably provided in front of the case 10, and for example, the door 60 may be provided at one side of the front of the case 10 in a hinged manner, and open and close the storage space 16 in a pivotal manner.

Referring to fig. 1 to 3, fig. 2 is a schematic view of a refrigerating system 20 in a refrigerator 1 according to an embodiment of the present invention, and fig. 3 is a schematic front view of the refrigerator 1 according to an embodiment of the present invention. In some embodiments, the refrigerator 1 may further include a refrigeration system 20 for providing cold to the storage compartments. The refrigeration system 20 may further include a compressor 21, a condenser 22, a dew removing tube 23, a throttle device 24, an evaporator 25, and the like connected in series in the refrigerant flow path.

The compressor 21 is used as power of the refrigerating system 20, the bottom of the rear side of the cabinet 10 is provided with a compressor compartment 15, and the compressor 21 may be disposed in the compressor compartment 15 (as shown in fig. 1). The compressor 21 increases the pressure and temperature of the refrigerant vapor by compression, creating a condition for transferring heat of the refrigerant vapor to an external environment medium, i.e., compressing the low-temperature low-pressure refrigerant vapor to a high-temperature high-pressure state so that the refrigerant vapor can be condensed using normal-temperature air or water as a cooling medium.

The condenser 22 is also provided in the compressor compartment 15, and the condenser 22 is a heat exchange device that takes away heat of the high-temperature and high-pressure refrigerant vapor from the compressor 21 by using the environment, and cools and condenses the high-temperature and high-pressure refrigerant vapor into a refrigerant liquid at a high pressure and a normal temperature.

The dew removing pipe 23 is connected to the outlet of the condenser 22, and since the refrigerant at the outlet of the condenser 22 is at a normal temperature and the temperature of the refrigerant is high with respect to the storage compartment, the refrigerant can heat the surrounding members when passing through the dew removing pipe 23, and frost formation is avoided. Specifically, the dew removing tube 23 may be provided at a position of the cabinet 10 where heating dew removal is required, for example, in a center sill of the refrigerator 1 or the like.

A throttling device 24 (which may be a capillary tube) may be connected in series to the outlet of the condenser 22 to reduce the pressure and temperature of the refrigerant liquid, so as to change the refrigerant liquid discharged from the condenser 22 at a high pressure and a normal temperature into a low temperature and low pressure refrigerant, and then discharged into the evaporator 25 for phase change heat absorption.

An evaporator 25 may be provided in the cabinet 10 to directly or indirectly supply cold to the storage compartment of the refrigerator 1. For example, in the compression-type direct-cooling refrigerator 1, the evaporator 25 may be provided outside or inside the rear wall surface of the liner 13. In the compressed air-cooled refrigerator 1, an evaporator chamber is further arranged in the refrigerator body 10, the evaporator 25 chamber is communicated with the storage compartment through an air path system, the evaporator 25 is arranged in the evaporator chamber, and an air supply fan 50 is arranged at an outlet of the evaporator chamber so as to circularly refrigerate the storage compartment.

Referring to fig. 1 to 3, in some embodiments, the refrigerator 1 may further include a heat dissipation fan 40, where the heat dissipation fan 40 is disposed in the compressor compartment 15 to promote the formation of a heat dissipation air flow for heat exchange with the compressor 21 and the condenser 22, so as to implement forced convection heat exchange with the compressor 21 and the condenser 22, and improve heat dissipation efficiency.

Referring to fig. 1 and 3, in some embodiments, the refrigerator 1 may also use bottom air to dissipate heat from the press cabin 15. Specifically, the bottom of the press cabin 15 is provided with a heat radiation air flow inlet 150a. The cooling fan 40 can promote the air at the bottom of the box 10 to enter the compressor compartment 15 through the cooling airflow inlet 150a, and perform forced convection heat exchange with the compressor 21 and the condenser 22.

When the refrigerator 1 is embedded into a cabinet for use, because the heat dissipation space around the refrigerator 1 (especially at the left side and the right side) is compressed, the space, which is not shielded at the bottom of the refrigerator 1, can be fully utilized by adopting a bottom air inlet mode, so that the air inlet efficiency of the press cabin 15 is higher, and the refrigerator is more suitable for embedded scenes.

Referring to fig. 1 and 3, further, the condenser 22, the heat dissipation fan 40 and the compressor 21 are sequentially arranged from bottom to top. Because the heat dissipation air flow inlet 150a is arranged at the bottom of the compressor room 15, the air flow entering the compressor room 15 from the heat dissipation air flow inlet 150a can vertically pass through the condenser 22 and the compressor 21 in sequence, and can directly exchange heat with the condenser 22 and the compressor 21 without changing the flow direction of the air flow, so that the power loss caused by the change of the direction of the heat dissipation air flow is avoided, and the heat exchange efficiency is improved.

In addition, since the condenser 22, the heat dissipation fan 40 and the compressor 21 are sequentially arranged from bottom to top, that is, the compressor 21 is not directly contacted with the bottom of the compressor compartment 15, the vibration caused by the compressor 21 is reduced, and the noise caused by the compressor 21 is further reduced effectively.

In addition, since the condenser 22, the heat dissipation fan 40 and the compressor 21 are sequentially arranged from bottom to top, compared with the arrangement of the condenser 22, the heat dissipation fan 40 and the compressor 21 in the transverse direction, the layout manner of the embodiment can reduce the transverse width of the cabin 15. That is, the press cabin 15 does not occupy the entire lateral space of the bottom of the rear side of the case 10, and the released space can reasonably increase the depth of the storage space 16 and increase the capacity of the storage compartment.

To sum up, in the refrigerator 1 of the embodiment, the compressor compartment 15 adopts the bottom air intake, and the condenser 22, the heat dissipation fan 40 and the compressor 21 are sequentially arranged from bottom to top, so that the heat exchange efficiency inside the compressor compartment 15 is improved, the refrigerator 1 is more suitable for an embedded scene, the noise caused by the compressor 21 is reduced, and the accommodating capacity of the storage space 16 can be further improved. Thus, the layout of the present embodiment breaks the design constraints of the conventional nacelle 15 structure, with outstanding substantial features and significant advances.

Referring to fig. 1 and 3, in some embodiments, the refrigerator 1 further includes an air outlet duct 30, a first end of the air outlet duct 30 is connected to the top of the press compartment 15, a second end of the air outlet duct 30 is disposed at the front top of the cabinet 10 and is opened forward, and a second end of the air outlet duct 30 serves as a cooling air flow outlet 322. The heat radiation fan 40 is configured to cause air in the bottom space of the case 10 to enter the compressor compartment 15 from the heat radiation air flow inlet 150a, exchange heat with the compressor 21 and the condenser 22, and finally be discharged from the heat radiation air flow outlet 322.

That is, in the present embodiment, the passage path of the heat dissipation air flow may be (the dotted arrow in fig. 1 represents the heat dissipation air flow): firstly, air at the bottom of the box body 10 can enter the compressor room 15 through the heat dissipation air flow inlet 150a and then directly flows upwards to exchange heat with the condenser 22 and the compressor 21; then, since the first end of the air outlet duct 30 is connected to the top of the press cabin 15 and the second end of the air outlet duct 30 is disposed at the front top of the case 10, the heat dissipation air flow after heat exchange with the compressor 21 can flow into and out of the air outlet duct 30 through the first end of the air outlet duct 30 and finally be discharged through the heat dissipation air flow outlet 322 disposed at the front top of the case 10, thereby forming a circulation.

Since the front side top space of the case 10 is not shielded by the cabinet, the air flow discharge after the heat exchange is completed is not affected, which is advantageous to form a circulating air flow.

It should be noted that, in order not to affect the opening and closing of the upper door 60, the second end of the air outlet duct 30 is disposed at the front top of the case 10, which may be adjacent to the front edge of the case 10. In addition, the upper door 60 is not preferably higher than the upper surface of the case 10 in design to prevent the heat dissipation air flow from being discharged forward.

Referring to fig. 4, fig. 4 is a schematic view showing a top structure of a cabinet 10 in a refrigerator 1 according to an embodiment of the present invention. Further, in order to prevent foreign matters and the like from entering the air outlet duct 30, the heat dissipation air flow outlet 322 may be further provided with shielding means such as a filter screen, a louver 322a, and the like.

In addition, since the first end of the air outlet duct 30 is connected to the top of the compressor compartment 15 (the first end of the air outlet duct 30 is at a low position), and the second end of the air outlet duct 30 is disposed at the front top of the case 10 (the second end of the air outlet duct 30 is at a high position), the heat-dissipating air flow after heat exchange of the compressor compartment 15 needs to flow upward to be discharged out of the case 10. Since the cabin 15 is in a relatively high temperature environment, the air density in the cabin 15 is less than that of the ambient air, i.e. a chimney effect is formed, and the heat dissipation air flow in the cabin 15 can be naturally discharged out of the box 10 along the air outlet pipeline 30, so that a certain ventilation performance is maintained in the cabin 15 even in a state that the heat dissipation fan 40 is not started, the heat dissipation efficiency is further improved, and the additional energy consumption is reduced.

Referring to fig. 1 and 3, further, the air outlet duct 30 may further include a first pipe section 310 and a second pipe section 320. The first pipe section 310 has a first end connected to the top of the press compartment 15 and extends upward along the rear wall of the case 10, and the second pipe section 320 has a first end formed at the second end of the first pipe section 310 and extends forward along the top wall of the case 10 so that the second end thereof is at the top of the front side of the case 10.

The rear wall of the case 10 is understood to be formed by the rear plate of the housing 11, the rear wall of the liner 13, and the heat insulating layer 12 therebetween, and the top wall of the case 10 is understood to be formed by the top plate of the housing 11, the top wall of the liner 13, and the heat insulating layer 12 therebetween.

In some alternative embodiments, the first tube segment 310 may be disposed outside of the back panel of the housing 11 and extend upward to the top of the back panel, and then the second tube segment 320 extends forward from the top of the back panel along the top panel of the housing 11 to the front side.

Referring to fig. 1 and 3, in some alternative embodiments, first tube segment 310 and second tube segment 320 may also each correspond to insulation 12. That is, the first pipe section 310 is disposed in the insulation layer 12 between the rear back plate of the housing 11 and the rear wall of the liner 13, then extends upward to the insulation layer 12 between the top plate of the housing 11 and the top wall of the liner 13, and then extends forward, so that the front top of the cabinet 10 needs to be provided with an exposing hole (not shown) for exposing the second end of the second pipe section 320. This arrangement of the air outlet duct 30 can function as a hidden duct, making the refrigerator 1 more attractive.

Referring to fig. 1 and 3, in some embodiments, the condenser 22 is configured as a microchannel condenser 22 having a flat shape with a wider face disposed horizontally and facing the cooling airflow inlet 150a. The condenser 22 has a plurality of heat dissipating microchannels 220 extending through its wider sides for dissipating heat from the airflow through the condenser 22.

The condenser 22 is flat, and its wider one side level sets up, is favorable to making it be in steady state to can make to the maximum extent with the heat dissipation air current import 150a relatively, improve the heat dissipation air current and condenser 22 direct contact's area, and then improve heat exchange efficiency.

The plurality of heat dissipation micro-channels 220 on the condenser 22 penetrate through the wider two sides of the condenser, and as the wider side of the condenser 22 is horizontal, that is, the plurality of heat dissipation micro-channels 220 vertically penetrate through the condenser 22, the heat dissipation air flow smoothly passes through the condenser 22, and the ventilation of the heat dissipation air flow is further improved.

Referring to fig. 1 and 3, further, the refrigerator 1 may further include a bracket 70, the bracket 70 being located in the compressor compartment 15, the bracket 70 having a plurality of support columns distributed around the condenser 22, and the plurality of support columns being gathered upward and toward the center to support the compressor 21.

Referring to fig. 1 and 3, taking an embodiment of four support columns as an example, the four support columns may be uniformly distributed around the condenser 22 (e.g., four corners or four sides), the bottom end of each support column may be fixed to the bottom of the press cabin 15 by means of a clamping connection, a threaded connection, etc., each support column extends upward and then gathers toward the center, and the compressor 21 is seated on the top ends of the four support columns and is fixed by means of a clamping connection, a threaded connection, etc.

In addition, since the heat dissipation fan 40 is disposed above the condenser 22, the heat dissipation fan 40 is also disposed in the space surrounded by the four support columns, the condenser 22 can be fixed on the four support columns, and the heat dissipation fan 40 can also be fixed on the four support columns, so as to realize stable installation.

It should be noted that the number of the support columns can be flexibly selected according to the practical situation, but the number is not preferably less than three, so that the support 70 provides a stable fixing structure and sufficient mechanical strength.

It can be seen that this manner of mounting by the bracket 70 not only effectively positions and secures the condenser 22, the heat radiation fan 40 and the compressor 21, but also hardly affects the fluidity of the heat radiation air flow.

Referring to fig. 1 and 3, in some embodiments, the heat dissipation fan 40 is configured as an axial flow fan with the suction side of the heat dissipation fan 40 facing the plurality of heat dissipation micro-channels 220. The heat dissipation fan 40 may further include a fan frame 410 and a plurality of blades 420 disposed in the fan frame 410, where the fan frame 410 is horizontally disposed and its periphery is fixed on the support columns of the support 70.

The air inlet and outlet mode of the axial flow fan is axial air inlet and axial air outlet. The heat dissipation fan 40 is disposed above the condenser 22, and the compressor 21 is disposed above the fan heater, and the air suction side of the heat dissipation fan 40 faces the plurality of heat dissipation micro channels 220, so that the air outlet side of the heat dissipation fan 40 faces the bottom of the compressor 21. In this way, the air flow entering the compressor compartment 15 through the heat dissipating air flow inlet 150a may be directed to bypass the condenser 22 and the compressor 21 in a vertical order, thereby achieving forced convection heat transfer.

As can be seen from the above embodiments, since the heat dissipation fan 40 is disposed above the condenser 22, the heat dissipation fan 40 is also disposed in the space surrounded by the support columns, and the heat dissipation fan 40 can be fixed on the support columns to achieve stable installation. Specifically, an outer ring of the fan frame 410 of the heat radiation fan 40 may be respectively connected to each support column to achieve a stable arrangement of the heat radiation fan 40 between the condenser 22 and the compressor 21.

Referring to fig. 1 and 3, further, the orthographic projection of the compressor 21 to the heat dissipation fan 40 is at the center of the fan frame 410. That is, the compressor 21 is located at the axial center of the heat radiation fan 40, so that the heat radiation air flow blown out from the air outlet side of the heat radiation fan 40 can uniformly act on the compressor 21 to uniformly radiate heat.

The projected area of the compressor 21 to the heat radiation fan 40 is smaller than the area of the inner ring of the fan frame 410. That is, the area of the compressor 21 is smaller than the inner ring area of the fan frame 410 in the horizontal plane. The area of the air outlet side of the heat dissipation fan 40 is larger than the area of the compressor 21, so that the air flow exhausted from the air outlet side of the heat dissipation fan 40 can completely act on the compressor 21, and the compressor 21 can fully dissipate heat.

Referring to fig. 5, fig. 5 is an exploded view of a cabinet 10 in a refrigerator 1 according to an embodiment of the present invention. In some embodiments, the press cabin 15 includes a bottom steel 150, two side plates 152 connected to lateral side edges of the bottom steel 150, a back plate 154 connected to a rear edge of the bottom steel 150, and a cover plate 155 connected to a front edge of the bottom steel 150 and covering a top of the bottom steel 150. The heat dissipation air flow inlet 150a is provided at the bottom steel 150.

In some specific embodiments, the heat dissipating airflow inlet 150a may include a plurality of bottom air inlets on the bottom steel 150, each of the bottom air inlets being elongated, and the plurality of bottom air inlets being arranged in an array. Of course, the shape and arrangement of the heat dissipating airflow inlets 150a may be other ways. For example, in other embodiments, portions of the sheet sections of the base steel 150 may also be formed of wire mesh such that voids in the wire mesh act as the heat sink airflow inlets 150a.

Further, when the refrigerator 1 is used with the built-in cabinet, the front environment of the refrigerator 1 is better in circulation than the side of the refrigerator 1, and therefore, the heat dissipation air inlet 150a may be further provided at a position of the bottom steel 150 adjacent to the front edge, so that the air in front of the refrigerator 1 can be forced to flow into the bottom space and the heat dissipation air inlet 150a can be quickly flown into the press compartment 15.

The two side plates 152 serve as the left and right side walls of the press cabin 15, respectively. Since the amount of air intake from the heat dissipating air flow inlet 150a may already satisfy the ventilation amount of the compressor compartment 15, the side air inlet on the adjacent side plate 152 may be eliminated. Whether the refrigerator 1 is used independently or is embedded, the bottom air inlet mode can be adopted to ventilate the press cabin 15.

Furthermore, the back plate 154 serves as a rear wall of the press cabin 15. Therefore, in order to avoid the air leakage phenomenon, the heat dissipation air flow is prevented from being discharged out of the pressure cabin 15 without passing through the compressor 21, and no air outlet is arranged on the back plate 154.

Referring to fig. 1, in some embodiments, the cover plate 155 is disposed in a circular arc shape, and the top end of the cover plate 155 is connected to the first end of the air outlet duct 30.

Since the cover plate 155 serves as the top wall of the compressor compartment 15 and the entire compressor compartment 15 is generally positioned farther forward than the rear wall of the housing 10, the heat-exchanged heat-dissipating air flow needs to flow backward into the air outlet duct 30. The cover plate 155 is arranged in an arc shape, so that the heat dissipation airflow smoothly flows into and out of the air duct 30 along the cover plate 155, and the power loss is reduced.

In addition, since the top end of the cover 155 is connected to the first end of the air outlet duct 30, the cover 155 may be configured to be connected to the first end of the air outlet duct 30 from front to back, so that the nacelle 15 and the air outlet duct 30 integrally form a "tapered" channel, which is more beneficial for the upward acceleration of the heat dissipation airflow.

Referring to fig. 1, 3 and 5, in some embodiments, the press bay 15 is on a lateral side of the housing 10. Because the condenser 22, the heat radiation fan 40 and the compressor 21 are sequentially arranged from bottom to top, the transverse width of the press cabin 15 is smaller, and the transverse width of the released box body 10 can be used for arranging the evaporator 25, so that the overall structure of the refrigerator 1 is more reasonable.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
