[0079] The present application will be described in detail below with reference to the accompanying drawings. However, the embodiments shown in the drawings are not intended to limit the present application, and any changes in structure, method, or function made by those skilled in the art based on the embodiments are included in the scope of the present application.

[0080] As shown in FIG. 1, in one embodiment, the refrigerator 10 includes a cabinet 100 and a storage container 200 in any of the embodiments described below. The cabinet 100 has a receiving chamber 101 formed therein. The storage container 200 is disposed in the receiving chamber 101.

[0081] It should be noted that the receiving chamber of the refrigerator is usually multiple, which is used to realize different functions. For example, a refrigeration chamber, a freezing chamber, a variable temperature chamber, etc. The number and function of the specific receiving chamber can be configured according to the pre-requisite. The storage container can be disposed in any receiving chamber. The refrigerator shown in FIG. 1 is only an example, and the number, function and layout of the specific receiving chamber can be configured according to the needs of those skilled in the art.

[0082] In addition, the refrigerator of the present embodiment is a forced air cooling refrigerator. A refrigeration space and an air path system are provided in the cabinet. A fan and a heat exchanger (evaporator) are provided in the refrigeration space. The fan is used to send the cold air that has been cooled by the heat exchanger to the receiving chamber through the cabinet air outlet, and then returns to the refrigeration space through the cabinet air return, thereby realizing the circulation of the air cooling. Since the cabinet, the door body and the refrigeration system of such a refrigerator are all known to those skilled in the art and easy to implement, in order not to obscure and obscure the application point of the present application, the cabinet, the door body and the refrigeration system itself will not be described below.

[0083] As shown in FIGS. 2 to 7, in one embodiment, the storage container 200 includes a barrel 210, a drawer 220, a top insulation layer 2311, a side insulation layer 240, a rear insulation layer 250 and a magnetic field assembly 260.

[0084] As shown in FIGS. 2 and 3, the barrel 210 forms a temperature-insulated chamber 201 with a front end opening. The drawer 220 is arranged in the temperature-insulated chamber 201 in a pullable manner. The drawer 220 is used to store the stored objects. In other words, the drawer 220 can be pulled out of the temperature-insulated chamber 201 or retracted into the temperature-insulated chamber 201 through the front end opening of the temperature-insulated chamber 201. When the drawer 220 is retracted into the temperature-insulated chamber 201, the front panel of the drawer 220 covers and seals the front end opening of the barrel 210.

[0085] As shown in FIGS. 2 to 4, the barrel 210 forms two chambers with front end openings and distributed left and right, one of which is the temperature-insulated chamber 201, and the other is the normal refrigeration chamber 202. In one embodiment, the left chamber is the temperature-insulated chamber 201, and the right chamber is the normal refrigeration chamber 202. The normal refrigeration chamber 202 is in communication with the receiving chamber 101 of the refrigerator 10, that is, it realizes the same refrigeration effect as other areas of the receiving chamber 101.

[0086] Referring to FIGS. 2-5, the temperature-insulated compartment 201 is used to store items with high preservation requirements or special cold storage needs, and thus is separately cooled and insulated from the outside. Alternatively, the right ordinary cooling compartment 202 can also be configured in the same way as the temperature-insulated compartment 201. In one embodiment, for the separate cooling of the temperature-insulated compartment 201, the storage container 200 is formed with a cold air circuit for cooling the temperature-insulated compartment 201. The cold air circuit is connected to the air supply port and the air return port of the refrigerator body, so that the cold air generated in the cooling space of the refrigerator can enter the cold air circuit and return to the cooling space after flowing through the cold air circuit, thereby completing the circulation cooling of the temperature-insulated compartment 201.

[0087] Continuing to refer to FIGS. 2-5, for the temperature-insulated structure of the temperature-insulated compartment 201, first, a thermal insulation layer is provided between the temperature-insulated compartment 201 and the ordinary cooling compartment 202 to achieve the temperature-insulating effect between the temperature-insulated compartment 201 and the ordinary cooling compartment 202. In other words, the temperature-insulated compartment 201 and the ordinary cooling compartment 202 share a side wall (the right side wall of the temperature-insulated compartment 201) with temperature-insulating effect. In addition, a top thermal insulation layer 2311 is provided outside the top wall of the temperature-insulated compartment 201, a side thermal insulation layer 240 is provided outside the left side wall of the temperature-insulated compartment 201, and a rear thermal insulation layer 250 is provided outside the rear side wall of the temperature-insulated compartment 201, thereby achieving the temperature-insulating effect between the temperature-insulated compartment 201 and the containing compartment 101.

[0088] It should be noted that the outside of the bottom side wall of the temperature-insulated compartment is also provided with a bottom thermal insulation layer. However, in other embodiments, because the bottom side wall of the barrel body can be well fitted to the wall of the body, the bottom thermal insulation layer can also not be provided.

[0089] In other embodiments, the storage container can also have only one temperature-insulated compartment, and both side walls can be provided with thermal insulation layers, or one side wall can be fitted to the wall of the body, so that the thermal insulation layer is provided only on one side wall.

[0090] As shown in FIGS. 2-7, the magnetic field assembly 260 includes two magnetic field generating modules 261. The two magnetic field generating modules 261 are respectively arranged on opposite sides of the temperature insulation chamber 201 to generate a magnetic field inside the temperature insulation chamber 201. In an embodiment, the two magnetic field generating modules 261 are respectively arranged on the top side and the bottom side of the temperature insulation chamber 201. The specific structure of the magnetic field generating module 261 can be arranged as described above. In addition, the magnetic field assembly 260 further includes two magnetic conductive connectors 262, which are respectively arranged on opposite sides (left and right) of the temperature insulation chamber 201, and each magnetic conductive connector 262 is used to connect the two magnetic field generating modules 261. The magnetic field assembly 260 and the magnetic field generating module 261 are respectively arranged on opposite sides of the temperature insulation chamber 201, that is, the magnetic field assembly 260 is arranged on the bottom side of the temperature insulation chamber 201. In addition, the fresh-keeping container 200 further includes two magnetic conductive connectors 262.

[0091] The two magnetic conductive connectors 262 are respectively arranged on opposite sides (left and right) of the temperature insulation chamber 201, and each magnetic conductive connector 262 is used to connect the magnetic field assembly 260 and the magnetic field generating module 261.

[0092] It should be noted that in other embodiments, the two magnetic field generating modules can also be arranged on the left and right sides or the front and rear sides of the temperature insulation chamber. Alternatively, in other embodiments, the magnetic conductive connectors can also not be arranged. In addition, in other embodiments, only one magnetic field generating module can be arranged, and the magnetic field generating module is arranged on one side of the temperature insulation chamber. In addition, in other embodiments, the magnetic field generating module 261 arranged on the bottom side can also not be arranged.

[0093] In the scheme of the present embodiment, by forming the temperature insulation chamber 201 for separate refrigeration and temperature insulation treatment in the storage container 200, and generating a magnetic field in the temperature insulation chamber 201 by using the magnetic field assembly 260, the inside of the temperature insulation chamber 201 can have a storage environment different from that of the storage chamber of the refrigerator, so that some stored objects with higher preservation requirements or special cold storage needs can be stored, which helps to ensure the preservation effect of the stored objects and improves the use experience.

[0094] In addition, the magnetic field generated by the magnetic field assembly 260 can act on the stored objects, that is, the stored objects are stored at low temperature under the assistance of the magnetic field. The magnetic field not only helps the food materials to maintain supercooling at a lower temperature, but also has a certain sterilization effect, thereby helping to further improve the preservation effect of the food material type stored objects.

[0095] By arranging the magnetic conductive connecting piece 262, the magnetic field generated by the magnetic field assembly 260 and the magnetic field generating module 261 can be guided and concentrated, which helps to concentrate the magnetic field generated by the magnetic field assembly 260 and the magnetic field generating module 261 in the temperature insulation chamber 201 and make the magnetic field more uniformly distributed in the temperature insulation chamber 201.

[0096] The structure of the storage container 200 will be further described in detail below with reference to the accompanying drawings.

[0097] As shown in FIGS. 8-10, in some embodiments, the barrel 210 includes an upper shell 2101 and a lower shell 2102, which are longitudinally spliced to form the outer side walls of the barrel 210. In an embodiment, the upper shell 2101 forms the top wall of the barrel 210, and the lower shell 2102 forms the bottom wall of the barrel 210. In addition, the upper shell 2101 and the lower shell 2102 are spliced together to form the left side wall, the right side wall, and the rear side wall of the barrel 210.

[0098] As can be understood by those skilled in the art, by arranging the barrel 210 in a structure spliced by the upper shell 2101 and the lower shell 2102, the components inside the barrel 210 can be installed first during the production process, and then the upper shell 2101 and the lower shell 2102 can be spliced, thereby facilitating the production and assembly of the barrel 210. In addition, during subsequent maintenance, the upper shell 2101 and the lower shell 2102 can be disassembled to maintain the inside of the barrel 210, thereby facilitating the maintenance of the barrel 210.

[0099] It should be noted that in other embodiments, the barrel can also be a one-piece structure, that is, the entire outer side wall of the barrel is a one-piece structure.

[0100] As shown in FIGS. 8-11, the upper shell 2101 and the lower shell 2102 are connected by a clamping structure. In an embodiment, the upper shell 2101 is provided with a clasp 2103, and the lower shell 2102 is provided with a clamping protrusion 2104, and the clasp 2103 is clamped to the clamping protrusion 2104 to achieve the connection between the upper shell 2101 and the lower shell 2102.

[0101] As shown in FIGS. 13-15, in some embodiments, the top of the side heat preservation layer 240 and the side of the top heat preservation layer 2311 are butted with a bending surface to form abutments in the left-right direction and the longitudinal direction. The top of the rear heat preservation layer 250 and the rear of the top heat preservation layer 2311 are butted with a bending surface to form abutments in the front-rear direction and the longitudinal direction. The side of the rear heat preservation layer 250 and the rear of the side heat preservation layer 240 are butted with a bending surface to form abutments in the front-rear direction and the left-right direction.

[0102] The skilled in the art can understand that, by making the top heat preservation layer 2311, the side heat preservation layer 240 and the back heat preservation layer 250 abut with each other by the bending surface, that is, making the contact surface between the heat preservation layers a bending surface, so that the two heat preservation layers can form a seal in at least two directions, not only helps to improve the sealing effect, but also the bending surface is not conducive to the flow of cold air, so that the cold air inside the heat preservation layer is not easy to flow out through the bending surface, and the external cold air is also not easy to enter the inside of the heat preservation layer through the bending surface, thereby improving the temperature insulation effect. In addition, the abutment between the heat preservation layers by the bending surface can also have a positioning effect on the assembly of the two heat preservation layers, thereby facilitating the assembly work between the heat preservation layers.

[0103] As shown in FIGS. 13, 16-20, the side portion of the top heat preservation layer 2311 is formed with a first protruding rib 234 extending in the front-rear direction and protruding towards the direction of the barrel body 210. The top portion of the side heat preservation layer 240 is formed with a second protruding rib 241 extending in the front-rear direction and protruding upwards. The first protruding rib 234 and the second protruding rib 241 abut in the left-right direction, the bottom surface of the first protruding rib 234 abuts with the side heat preservation layer 240, and the top surface of the second protruding rib 241 abuts with the top heat preservation layer 2311, so that the side heat preservation layer 240 and the top heat preservation layer 2311 abut with each other by the bending surface formed by the transverse surface, the longitudinal surface and the transverse surface in sequence.

[0118] The skilled in the art can understand that, by setting the side positioning protrusion 2105 on the barrel body 210 and the first positioning groove 243 on the side heat preservation layer 240, the side positioning protrusion 2105 can be embedded in the first positioning groove 243 to position the installation position of the side heat preservation layer 240, thereby playing a role of preliminary positioning for the side heat preservation layer 240 in the assembly process of the side heat preservation layer 240 and the barrel body 210, and more facilitating the installation of the side heat preservation layer 240. In addition, the embedding of the side positioning protrusion 2105 in the first positioning groove 243 can also make the side heat preservation layer 240 and the barrel body 210 cooperate more stably after being assembled in place.

[0133] As can be understood by those skilled in the art, by forming the front stop rib 2113 at the front end of the barrel body 210, the side insulation layer 240 can be limited by the front stop rib 2113, which not only positions the installation of the side insulation layer 240, but also helps to improve the stability of the assembly of the side insulation layer 240 and the barrel body 210.

[0134] As shown in FIGS. 8-10, the rear side wall of the barrel 210 is formed with a rear retaining rib 2114 extending rearward, which abuts against the side of the rear thermal insulation layer 250. In an embodiment, the rear retaining rib 2114 is formed by extending the rear side wall of the barrel 210 in the direction of the rear thermal insulation layer 250 and extending longitudinally, so as to abut against the side of the rear thermal insulation layer 250.

On the other hand, the magnetic uniformity plate 2612 can guide the magnetic field generated by the permanent magnetic sheet 2611, thereby further improving the uniformity of the magnetic field generated by the permanent magnetic sheet 2611 in the temperature insulation chamber 201.

[0142] It should be noted that in other embodiments, the magnetic field generating module can also be only one large permanent magnetic sheet, and the permanent magnetic sheet and the top heat preservation layer 2311 form the refrigeration air duct. Alternatively, the magnetic field generating module is an electromagnetic coil.

[0143] As shown in FIGS. 2-5, the refrigeration air circuit for the temperature insulation chamber 201 surrounds the interior space of the drawer 220, including a top section 203 located at the top side of the interior space of the drawer 220, a front section 204 located at the front side of the interior space of the drawer 220, and a bottom section 205 located at the bottom of the interior space of the drawer 220.

The air inlet 206 is docked with the air outlet of the refrigeration space of the refrigerator cabinet, so that the cold air generated by the refrigeration space can enter the refrigeration air duct of the top section 203 through the air inlet 206. That is, the refrigeration air duct communicates with the refrigeration source of the refrigerator through the air inlet 206.

[0145] Referring to FIGS. 2-5, the front section 204 is formed inside the front panel of the drawer 220. In an embodiment, that is, the front panel of the drawer 220 has a relatively thick and hollow portion for forming the front section 204. In addition, the top of the front section 204 has an opening, and the front end of the top section 203 has an opening.

[0148] As can be understood by those skilled in the art, through the above structure, while achieving refrigeration of the internal space of the drawer 220, the cold air is prevented from directly blowing on the internal space of the drawer 220, so as to avoid the temperature of the stored objects placed in the internal space of the drawer 220 from dropping too fast, thereby achieving a gentle temperature drop required for magnetic field preservation, and better achieving magnetic field preservation.

[0149] It should be noted that in other embodiments, only the top section can be provided, and the cold air flow directly flows out of the storage container from the front of the top section and enters the containing compartment of the refrigerator.

The refrigeration air duct 2031 is isolated from and abuts the temperature insulation chamber 201, and is capable of conducting cold energy to the temperature insulation chamber 201. The plurality of flow distribution columns 232 are arranged in the refrigeration air duct, and are used to disperse the airflow flowing through the refrigeration air duct 2031 in the width direction of the refrigeration air duct.

[0156] The air duct 231 is arranged outside the top side wall of the barrel 210. The air duct 231 comprises a top thermal insulation layer 2311 and a magnetic field generation module 261.

[0157] In an embodiment, the top thermal insulation layer 2311 and the magnetic field generation module 261 are both plate-shaped. The side of the top thermal insulation layer 2311 that faces the magnetic field generation module 261 is formed with a recess that extends from the rear end to the front end. After the top thermal insulation layer 2311 and the magnetic field generation module 261 are assembled in place, the recessed surface of the top thermal insulation layer 2311 and the top surface of the magnetic field generation module 261 jointly form the refrigeration air duct 2031 that extends from the rear end to the front end of the barrel 210. The refrigeration air duct 2031 is isolated from and abuts the temperature insulation chamber 201 via the magnetic field generation module 261 and the top side wall of the barrel 210.

[0158] The plurality of flow distribution columns 232 are arranged in multiple rows along the flow direction of the airflow in the refrigeration air duct 2031.

The flow distribution columns 232 are formed by the side of the top thermal insulation layer 2311 that faces the magnetic field generation module 261 being raised towards the magnetic field generation module 261, i.e., the flow distribution columns 232 are integrally formed with the top thermal insulation layer 2311.

[0159] In the present embodiment, the flow distribution columns 232 can be integrally formed with the air duct; in other embodiments, the flow distribution columns 232 can be separately formed and fixed in the refrigeration air duct 2031.

[0160] The size of the refrigeration air duct 2031 in the width direction perpendicular to the direction of the air flow, that is, the direction of the air flow in the refrigeration air duct 2031 from the back to the front along the barrel 210, the width of the refrigeration air duct 2031, that is, the size in the left-right direction of the barrel 210. When the air flow flows in the refrigeration air duct 2031 from the back to the front along the barrel 210, it is dispersed to the left and right sides by the flow dividing column 232, so that the air flow is more dispersed in the left-right direction. As the air flow continues to flow forward in the refrigeration air duct 2031, the air flow is continuously dispersed by the flow dividing column 232, so that the air flow is fully and uniformly diffused in the refrigeration air duct 2031. The cold energy carried by the air flow can be conducted into the temperature insulation chamber 201 through the magnetic field generating module 261 and the top side wall of the barrel 210. Because the air flow is fully and uniformly diffused in the refrigeration air duct 2031, the refrigeration effect on the temperature insulation chamber 201 is more uniform.

[0161] In the scheme of the present embodiment, the refrigeration air duct 2031 is formed by using the air duct piece 231, and a plurality of flow dividing columns 232 are arranged in the refrigeration air duct 2031. When the air flow flows in the refrigeration air duct 2031, it will encounter the flow dividing column 232, and be dispersed to both sides by the flow dividing column 232. Because the volume of the flow dividing column 232 is relatively small, it does not occupy too much space in the refrigeration air duct 2031 compared with the flow guide ribs extending in the direction of the air flow, so that the air flow can be fully and uniformly diffused in the refrigeration air duct 2031. In this way, whether the air flow is directly sent into the temperature insulation chamber or the cold energy is conducted to the temperature insulation chamber in the form of heat conduction, the cold energy can uniformly cool the temperature insulation chamber, improve the uniformity of the refrigeration effect in the temperature insulation chamber, and thus improve the preservation effect of the stored objects in the temperature insulation chamber. In the form of conducting cold energy, the cold air can also avoid directly blowing on the stored objects, further improving the preservation effect of the stored objects.

[0162] By using the barrel 210 to form the temperature insulation chamber 201, and using the top heat preservation layer 2311 and the magnetic field generating module 261 to constitute the air guide assembly 230, on the basis of uniformly cooling the temperature insulation chamber 201, the magnetic field generating module 261 can generate a magnetic field acting on the temperature insulation chamber 201, thereby realizing magnetic field preservation storage of the stored objects. The magnetic field not only helps the food materials to maintain supercooling degree at a lower temperature, but also has a certain sterilization effect, thereby helping to improve the preservation effect of the food material type stored objects. Moreover, the top heat preservation layer 2311 can have a temperature insulation effect, avoid the leakage of cold energy of the air flow, and improve the utilization efficiency of the cold energy.

[0163] In addition, because the air flow is dispersed by the flow splitting column 232, the air flow is more gentle while the temperature of the temperature insulation chamber 201 is uniformly cooled, so as to avoid the temperature of the temperature insulation chamber 201 from dropping too fast, and then the temperature requirement of the magnetic field preservation can be reached more gently, so as to avoid the temperature from passing the temperature range of the magnetic field preservation too fast, and the magnetic field preservation is more beneficial. In the conduction cooling mode, the temperature of the temperature insulation chamber 201 can be prevented from dropping too fast, and the magnetic field preservation effect is further improved.

[0164] In addition, the plurality of flow splitting columns 232 are arranged in multiple rows along the flow direction of the air flow in the refrigeration air duct 2031, and each row is provided with at least one flow splitting column 232. When the air flow flows in the refrigeration air duct 2031, the air flow is dispersed by each row of flow splitting columns 232 as the air flow continuously flows forward in the refrigeration air duct 2031, and the dispersion effect of the air flow is improved.

[0165] It should be noted that in other embodiments, the air guide assembly can also have other structures, for example, a plastic shell is used as the air guide assembly. In addition, the air guide assembly can be composed of the top heat preservation layer and the side wall of the barrel body.

[0166] In addition, it should be noted that in other embodiments, the refrigeration air duct can also directly supply air to the temperature insulation chamber, for example, a through hole is arranged on the top side wall of the barrel body and the magnetic field generating module, and air is supplied to the temperature insulation chamber through the through hole.

[0167] In other embodiments, only the refrigeration air duct can be arranged, and the cold air flow directly flows out of the storage container from the front of the refrigeration air duct and enters the containing chamber of the refrigerator. Alternatively, a through hole is arranged on the top side wall of the barrel body and the magnetic field generating module, air is supplied to the temperature insulation chamber through the through hole, and then the air is returned to the refrigeration space of the refrigerator cabinet through the air passing hole 2116 and the air outlet 207.

[0168] Referring to FIG. 24, in one embodiment, the flow splitting column 232 is an elliptical column, the long diameter end of the elliptical column faces the air inlet of the refrigeration air duct 2031, and the side surface of the elliptical column is closer to the streamline shape, so that the air flow is dispersed and the flow of the air flow is better and smoother.

[0169] Continuing to refer to FIG. 24, along the flow direction of the air flow in the refrigeration air duct 2031, the plurality of flow splitting columns 232 are arranged in multiple rows, and each row is provided with at least one flow splitting column 232. In each row of flow splitting columns 232, the end of the flow splitting column 232 close to the air inlet end of the refrigeration air duct 2031 is inclined to the center of the distribution direction, which deviates from the center of the distribution direction of all flow splitting columns 232.

[0170] As shown in FIG. 24, in an embodiment, the upper end of the figure is the air inlet end of the refrigeration air duct 2031, and the distribution columns 232 in each row are distributed along the left-right direction. As shown in the first row of the figure, there are two distribution columns 232, one on the left side of the center of the distribution direction and one on the right side of the center of the distribution direction, and the upper end of the distribution column 232 on the left side is inclined to the right, and the upper end of the distribution column 232 on the right side is inclined to the left. Through the above structure, the distribution column 232 can better guide the airflow to the edge of the refrigeration air duct 2031, which helps to improve the uniformity of the airflow distribution in the refrigeration air duct 2031.

[0171] Referring to FIG. 24, the number of rows of the distribution column 232 is set according to the approximate value of the calculation result of the row number calculation formula. The approximate value of the calculation result of the row number calculation formula is the integer value after rounding off the calculation result.

[0172] The row number calculation formula is: N = 30 x H / S;

[0173] Wherein, N is the number of rows of the distribution column; H is the length of the refrigeration air duct in the airflow direction, unit m; S is the flow rate of the airflow in the refrigeration air duct, unit m / s. That is, the number of rows of the distribution column is set according to the calculation result of 30 times the length of the refrigeration air duct in the airflow direction, divided by the square root of the flow rate of the airflow in the refrigeration air duct.

[0174] As shown in the plane in FIG. 24, the upper end is the air inlet end of the refrigeration air duct, the lower end is the air outlet end of the refrigeration air duct, the airflow direction is from top to bottom, and H is the length of the refrigeration air duct in the up-down direction.

[0175] For example, when H = 0.35 m and S = 3 m / s, N = 6, that is, 6 rows of distribution columns are set.

[0176] In the scheme of the embodiment, by setting the number of rows of the distribution column according to the length of the refrigeration air duct in the airflow direction and the flow rate of the airflow in the refrigeration air duct, the number of rows of the distribution column is set more reasonably, which helps to avoid excessive blocking of the airflow in the airflow direction due to too many rows of distribution columns, thereby ensuring better distribution effect and smooth airflow.

[0177] Referring to FIG. 24, the distance between the center line of all distribution columns 232 in each row and the air inlet end of the refrigeration air duct is set according to the approximate value of the calculation result of the row spacing calculation formula. The approximate value of the calculation result of the row spacing calculation formula is the value after rounding off the calculation result to two decimal places.

[0178] The row spacing calculation formula is: h n = n x H / (N + 1)

[0179] Wherein, h nThe distance between the center line of all the shunt columns in each row and the air inlet end of the refrigeration air duct is calculated according to the row number of the shunt columns in each row from the air inlet end of the refrigeration air duct multiplied by the length of the refrigeration air duct in the airflow direction, and then divided by the value obtained by adding one to the row number of the shunt columns.

[0180] As shown in FIG. 24, the distance h1 between the center line of all the shunt columns in the first row from the air inlet end of the refrigeration air duct and the air inlet end of the refrigeration air duct is illustrated, and the distance h2 between the center line of all the shunt columns in the second row from the air inlet end of the refrigeration air duct and the air inlet end of the refrigeration air duct is illustrated.

[0181] Exemplarily, when H = 0.35 m and N = 6, that is, in the case of setting 6 rows of shunt columns. For the first row of shunt columns from the air inlet end of the refrigeration air duct, n = 1, the distance h1 between the center line of all the shunt columns and the air inlet end of the refrigeration air duct is 0.05 m. For the sixth row of shunt columns from the air inlet end of the refrigeration air duct, n = 6, the distance h6 between the center line of all the shunt columns and the air inlet end of the refrigeration air duct is 0.30 m.

[0182] By setting the approximate value of the distance between the center line of all the shunt columns 232 in each row and the air inlet end of the refrigeration air duct according to the calculation result of the row spacing calculation formula, it is helpful to ensure that each row of shunt columns 232 has a proper row spacing.

[0183] Referring to FIG. 24, the number of shunt columns in each row is set according to the approximate value of the calculation result of the column number calculation formula. The approximate value of the calculation result of the column number calculation formula is the integer value obtained by rounding off the calculation result.

[0184] The column number calculation formula is: M = 35 × d / √S

[0185] Wherein, M is the number of shunt columns in each row; d is the width of the refrigeration air duct at the position of each row of shunt columns, in units of m; and S is the flow rate of the airflow in the refrigeration air duct, in units of m / s. The width of the refrigeration air duct at the position of each row of shunt columns is the dimension of the refrigeration air duct in the direction of the center line of the plurality of shunt columns. That is, the number of shunt columns in each row is set according to the calculation result of 35 multiplied by the width of the refrigeration air duct at the position of each row of shunt columns, and then divided by the flow rate of the airflow in the refrigeration air duct under the square root.

[0186] As shown in FIG. 24, the width d of the refrigeration air duct at the position of the third row of shunt columns counted from top to bottom is illustrated.

[0187] Exemplarily, when S = 3 m / s, the width d of the refrigeration air duct at the position of one row of the shunt columns is 0.1 m, and M = 2, that is, two shunt columns are arranged. The width d of the refrigeration air duct at the position of another row of the shunt columns is 0.2 m, and M = 4, that is, four shunt columns are arranged.

[0188] Referring to FIG. 24, the distance between the two endmost shunt columns 232 in each row of the shunt columns 232 and the side of the refrigeration air duct is set according to an approximate value of the calculation result of the side column distance calculation formula. The approximate value of the calculation result of the side column distance calculation formula is a value obtained by rounding off the calculation result to two or three decimal places.

[0189] The side column distance calculation formula is A = d / 2M

[0190] wherein A is the distance between the two endmost shunt columns in each row of the shunt columns and the side of the refrigeration air duct, in units of m; d is the width of the refrigeration air duct at the position of each row of the shunt columns, in units of m; and M is the number of shunt columns in each row. That is, the distance between the two endmost shunt columns in each row of the shunt columns and the side of the refrigeration air duct is set according to the calculation result of the width of the refrigeration air duct at the position of each row of the shunt columns divided by twice the number of shunt columns in each row.

[0191] As shown in FIG. 24, the distance A between the rightmost shunt column in the last row and the side of the refrigeration air duct is illustrated.

[0192] Exemplarily, when d = 0.1 m and M = 2, A is equal to 0.025 m. When d = 0.13 m and M = 3, A is equal to 0.02 m.

[0193] Referring to FIG. 24, the distance between the two adjacent shunt columns in each row of the shunt columns 232 is set according to an approximate value of the calculation result of the column distance calculation formula. The approximate value of the calculation result of the column distance calculation formula is a value obtained by rounding off the calculation result to two or three decimal places.

[0194] The column distance calculation formula is B = d / M

[0195] wherein B is the distance between the two adjacent shunt columns in each row of the shunt columns, in units of m; d is the width of the refrigeration air duct at the position of each row of the shunt columns, in units of m; and M is the number of shunt columns in each row. That is, the distance between the two adjacent shunt columns in each row of the shunt columns is set according to the calculation result of the width of the refrigeration air duct at the position of each row of the shunt columns divided by the number of shunt columns in each row.

[0196] As shown in FIG. 24, the distance B between the two adjacent shunt columns in the last row of the shunt columns is illustrated.

[0197] Exemplarily, when d=0.1m and M=2, B is equal to 0.05m. When d=0.13m and M=3, B is equal to 0.04m.

[0198] Through the above setting, the spacing between each row of shunt columns and the spacing between the two end shunt columns and the side of the refrigeration air duct are appropriate, and the airflow dispersion effect is good.

[0199] Referring to FIG. 24, in the case of an elliptical column, the minor axis of the elliptical column is set according to the approximate value of the calculation result of the minor axis calculation formula, and the major axis of the elliptical column is set according to the approximate value of the calculation result of the major axis calculation formula. The approximate value of the calculation result of the minor axis calculation formula and the approximate value of the calculation result of the major axis calculation formula are values rounded to two or three decimal places.

[0200] The minor axis calculation formula is: R=√D / (80×√S);

[0201] The major axis calculation formula is: L=√D / (40×√S);

[0202] Wherein, R is the minor axis of the elliptical column, unit m; L is the major axis of the elliptical column, unit m; D is the maximum width of the refrigeration air duct, unit m; S is the flow rate of the airflow in the refrigeration air duct, unit m / s.

The major axis of the elliptical column is set according to the calculation result of the maximum width of the refrigeration air duct divided by 40, and then divided by the flow rate of the airflow in the refrigeration air duct.
