[0060] As described in the background technology, the pressure reducing tube (capillary tube) is a mechanism with throttling and pressure reducing effect. Due to its simple structure, low cost, stable operation and no moving parts, it is still widely used in vapor compression systems such as refrigerators or freezers. Reheating the pressure reducing tube and the suction pipe at the inlet of the compressor can increase the inlet temperature of the compressor and prevent condensation. At the same time, the outlet enthalpy of the pressure reducing tube is reduced, and the evaporator cooling capacity is increased, thereby significantly improving the energy efficiency of the refrigerator or freezer.
[0061] See also Figure 1 and Figure 2 As shown, in the related art, the heat exchange between the pressure reducing pipe 330 and the air intake pipe 350 is mostly performed by a single pressure reducing pipe passing through or contacting the side. The heat exchange efficiency between the pressure reducing pipe 330 and the air intake pipe 350 of the compressor is low, and the effect is poor.
[0062] In order to solve the above technical problems, the refrigeration equipment provided by the present application has a part of the pressure reducing pipe located in the air intake pipe, and a part of the pressure reducing pipe abuts against the outer wall of the air intake pipe. In this way, the pressure reducing pipe can contact the outer wall of the air intake pipe to exchange heat, and can also contact the refrigerant in the air intake pipe to exchange heat, so that the heat exchange efficiency is high and the effect is good.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0068] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0069] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0070] This embodiment provides a refrigeration device, which may be a refrigerator, a freezer, or an air conditioner, etc. A refrigerator is taken as an example for description below.
[0071] See also Figure 3 and Figure 4 As shown, the refrigerator includes a cabinet 100 , a door 200 and a refrigeration system 300 .
[0072] The box 100 may define a storage room, and there may be at least one storage room. When the number of the storage room is one, the storage room may be any one of a refrigerating room, a freezing room, or a temperature-changing room. When the number of the storage rooms is two or more, the plurality of storage rooms may include at least one or more of the refrigerating room, the freezing room, or the temperature-changing room.
[0073] The door body 200 is an openable cover disposed on the front side of the box body 100 to close and open the storage room and to take and put items in the storage room. It should be noted that the number of the door body 200 can be one, two or more.
[0074] The refrigeration system 300 is located in the housing 100 . The refrigeration system 300 may include a compressor 310 , a condenser 320 , a pressure reducing pipe 330 , an evaporator 340 and an air suction pipe 350 .
[0075] The refrigerant flows out from the outlet end of the compressor 310, and flows into the inlet end of the compressor 310 through the condenser 320, the pressure reducing pipe 330, the evaporator 340 and the suction pipe 350 in sequence, and the refrigerant flows in the pipeline.
[0076] Specifically, when the compressor 310 is working, low-temperature, low-pressure refrigerant is sucked into the compressor 310 , compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 310 , and then discharged into the condenser 320 .
[0077] The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser 320, and the temperature continues to drop, and is gradually cooled into a saturated vapor at room temperature and high pressure, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process.
[0078] The condensed refrigerant saturated liquid is throttled and depressurized through the pressure reducing pipe 330, and the refrigerant becomes wet steam at room temperature and low pressure.
[0079] Afterwards, the normal temperature and low pressure wet steam absorbs heat and vaporizes through the evaporator 340, which not only reduces the temperature of the evaporator 340 and its surroundings, but also turns the refrigerant into a low temperature and low pressure gas. The evaporator 340 cools the air to reduce the temperature of the storage room.
[0080] The refrigerant coming out of the evaporator 340 returns to the compressor 310 again, and the above process is repeated, so that the evaporator 340 can continue to cool the air, thereby maintaining the storage room at a set temperature.
[0081] Furthermore, the refrigeration system 300 may further include a drying filter, which is connected between the condenser 320 and the suction pipe 350 through a pipeline, and the drying filter can filter out moisture and impurities in the refrigerant.
[0082] It should be noted that by recovering heat between the pressure reducing pipe 330 and the suction pipe 350 at the inlet end of the compressor 310, the inlet temperature of the compressor 310 can be increased to prevent condensation. At the same time, the outlet enthalpy of the pressure reducing pipe 330 is reduced, the cooling capacity of the evaporator 340 is increased, and the energy efficiency of the refrigerator can be improved.
[0083] See also Figure 5 and Figure 6 As shown, in this embodiment, in order to improve the heat exchange efficiency between the pressure reducing pipe 330 and the air intake pipe 350 and improve the heat exchange effect, the pressure reducing pipe 330 is configured to contact the outer wall of the air intake pipe 350 for heat exchange and to contact the refrigerant in the air intake pipe 350 for heat exchange.
[0084] Specifically, part of the pressure reducing pipe 330 is located in the air intake pipe 350 , and part of the pressure reducing pipe 330 abuts against the outer wall of the air intake pipe 350 .
[0085] It is understandable that, compared with the related art, the pressure reducing pipe 330 contacts the refrigerant in the air intake pipe 350 by internal penetration to perform heat exchange. Alternatively, compared with the related art, the pressure reducing pipe 330 performs heat exchange by side contact. In this embodiment, the pressure reducing pipe 330 simultaneously contacts the outer wall of the air intake pipe 350 and the refrigerant to perform heat exchange, which has a higher heat exchange efficiency and better effect.
[0086] In some embodiments of the present application, the pressure reducing pipe 330 includes an inlet pipe section 331, a first pipe section 332, a second pipe section 333 and an outlet pipe section 334 which are connected in sequence.
[0087] The first pipe section 332 abuts against the outer wall of the air intake pipe 350, the second pipe section 333 is located inside the air intake pipe 350, the inlet pipe section 331 is connected to the condenser 320, and the outlet pipe section 334 is connected to the evaporator 340. This is beneficial to the spatial layout of the refrigeration system 300.
[0088] Exemplarily, the inlet pipe section 331, the first pipe section 332, the second pipe section 333 and the outlet pipe section 334, the first pipe section 332 and the air intake pipe 350 can be round pipes. The inlet pipe section 331, the first pipe section 332, the second pipe section 333 and the outlet pipe section 334, the first pipe section 332 and the air intake pipe 350 can be copper pipes.
[0089] It should be noted that in other embodiments, the second pipe section 333 can be in contact with the outer wall of the intake pipe 350, the first pipe section 332 can be located inside the intake pipe 350, the inlet pipe section 331 is connected to the condenser 320, and the outlet pipe section 334 is connected to the evaporator 340, which will not be elaborated here.
[0090] See also Figure 5As shown, in a possible implementation, the extension direction of the first pipe segment 332 is consistent with the extension direction of the air intake pipe 350, the outer wall of the first pipe segment 332 abuts against the outer wall of the air intake pipe 350, and at least part of the first pipe segment 332 is located in the first area of the air intake pipe 350. The first area is the area where the second pipe segment 333 is sleeved.
[0091] It is understandable that the second pipe section 333 is located inside the air intake pipe 350, the outer wall of the first pipe section 332 abuts against the outer wall of the air intake pipe 350, and part or all of the first pipe section 332 is located in the first area of the air intake pipe 350. In this way, when the length of the pressure reducing pipe 330 is constant, the first pipe section 332 and the second pipe section 333 of the pressure reducing pipe 330 jointly utilize the first area of the air intake pipe 350, thereby improving the heat exchange efficiency while reducing the length of the air intake pipe 350, which is conducive to reducing space occupation and reducing costs.
[0092] In some embodiments, the first pipe section 332 may be fixed to the outer wall of the air intake pipe 350 by wrapping with adhesive aluminum foil.
[0093] It can be understood that the direction indicated by the arrow in the figure is the flow direction of the refrigerant.
[0094] See also Figure 6 As shown, in another possible implementation, the first pipe segment 332 is wound around the air intake pipe 350 , and the outer wall of the first pipe segment 332 abuts against the outer wall of the air intake pipe 350 .
[0095] It can be understood that, compared with the extension direction of the first pipe segment 332 being consistent with the extension direction of the intake pipe 350, the outer wall of the first pipe segment 332 abuts against the outer wall of the intake pipe 350, and the first pipe segment 332 is wound around the intake pipe 350 to increase the contact area between the first pipe segment 332 and the intake pipe 350, which is beneficial to improve the heat exchange efficiency and the heat exchange effect.
[0096] It should be noted that, in some embodiments, in order to further reduce the length of the air intake pipe 350, the first pipe section 332 may be arranged around the first area, wherein the first area is the area where the second pipe section 333 is arranged.
[0097] It can be understood that the direction indicated by the arrow in the figure is the flow direction of the refrigerant.
[0098] See also Figures 7 to 10As shown, in this embodiment, in order to further improve the heat exchange efficiency and heat exchange effect, the pressure reducing pipe 330 also includes a third pipe section 335, the inlet pipe section 331, the first pipe section 332, the second pipe section 333, the third pipe section 335 and the outlet pipe section 334 are connected in sequence, the first pipe section 332 abuts against the outer wall of the intake pipe 350, the second pipe section 333 is located inside the intake pipe 350, the third pipe section 335 abuts against the outer wall of the intake pipe 350, the inlet pipe section 331 is connected to the condenser 320, and the outlet pipe section 334 is connected to the evaporator 340.
[0099] It can be understood that the efficiency and effect of heat exchange can be improved by having the first pipe section 332, the second pipe section 333, and the third pipe section 335 simultaneously exchange heat with the intake pipe 350.
[0100] See also Figure 7 and Figure 8 As shown, in some embodiments, the extension direction of the third pipe segment 335 is consistent with the extension direction of the air intake pipe 350, and the outer wall of the third pipe segment 335 abuts against the outer wall of the air intake pipe 350. At least part of the third pipe segment 335 is located in the first area of the air intake pipe 350, and the first area is the area where the second pipe segment 333 is sleeved.
[0101] In this way, when the length of the pressure reducing pipe 330 is constant, the third pipe section 335 and the second pipe section 333 of the pressure reducing pipe 330 jointly utilize the first area of the intake pipe 350, so that the length of the intake pipe 350 can be reduced while improving the heat exchange efficiency, which is beneficial to reduce space occupancy and reduce costs.
[0102] In some embodiments, the third pipe section 335 can be fixed to the outer wall of the air intake pipe 350 by wrapping with adhesive aluminum foil.
[0103] In this embodiment, the extension direction of the first pipe segment 332 is consistent with the extension direction of the air intake pipe 350, and the center line of the first pipe segment 332 and the center line of the third pipe segment 335 are symmetrically arranged with respect to the center line of the air intake pipe 350. In other words, the first pipe segment 332 and the third pipe segment 335 are located at two sides of the air intake pipe 350 at an angle of 180°. In this way, it is conducive to the spatial layout setting and facilitates the assembly requirements in the refrigerator production process.
[0104] It is understandable that the third pipe section 335, the second pipe section 333 and the first pipe section 332 of the pressure reducing pipe 330 can be located in the first area at the same time, and the third pipe section 335, the second pipe section 333 and the first pipe section 332 of the pressure reducing pipe 330 can simultaneously exchange heat with the air intake pipe 350, thereby increasing the heat exchange per unit length of the air intake pipe 350. In addition, the length of the air intake pipe 350 can be reduced.
[0105] For example, the first pipe section 332 and the third pipe section 335 may be fixed to the outer wall of the air intake pipe 350 by wrapping with adhesive aluminum foil.
[0106] See also Fig. 9 As shown, in some embodiments of the present application, the third pipe section 335 is wound around the air intake pipe 350, and the outer wall of the third pipe section 335 abuts against the outer wall of the air intake pipe 350. In this way, the contact area between the third pipe section 335 and the air intake pipe 350 is large, which can improve the heat exchange efficiency and the effect of heat exchange.
[0107] Specifically, the first pipe segment 332 and the third pipe segment 335 are located on both sides of the second pipe segment 333 along the extension direction, the first pipe segment 332 is wound around the air intake pipe 350, and the outer wall of the first pipe segment 332 abuts against the outer wall of the air intake pipe 350. The second pipe segment 333 is located inside the air intake pipe 350, the third pipe segment 335 is wound around the air intake pipe 350, and the outer wall of the third pipe segment 335 abuts against the outer wall of the air intake pipe 350.
[0108] It can be understood that the direction indicated by the arrow in the figure is the flow direction of the refrigerant.
[0109] See also Fig.10 As shown, the first pipe segment 332 and the third pipe segment 335 are located on both sides of the second pipe segment 333 along the extension direction, the first pipe segment 332 is wound around the air intake pipe 350, and the outer wall of the first pipe segment 332 abuts against the outer wall of the air intake pipe 350. The extension direction of the third pipe segment 335 is consistent with the extension direction of the air intake pipe 350, and the outer wall of the third pipe segment 335 abuts against the outer wall of the air intake pipe 350.
[0110] It can be understood that the direction indicated by the arrow in the figure is the flow direction of the refrigerant.
[0111] In some embodiments, the third pipe section 335 can be fixed to the outer wall of the air intake pipe 350 by wrapping with adhesive aluminum foil.
[0112] In other embodiments, the center line of the second pipe section 333 is colinear with the center line of the suction pipe 350. In this way, the disturbance of the refrigerant flow in the suction pipe 350 can be reduced, and a better heat exchange effect can be achieved.
[0113] Exemplarily, when the second pipe section 333 and the air intake pipe 350 are circular pipes, the axis of the second pipe section 333 and the axis of the air intake pipe 350 are collinear.
[0114] In some embodiments of the present application, in order to improve sealing, the end of the second pipe section 333 close to the first pipe section 332 is inserted on the side wall of the suction pipe 350 and welded to the suction pipe 350. The end of the second pipe section 333 away from the first pipe section 332 is inserted on the side wall of the suction pipe 350 and welded to the suction pipe 350.
[0115] Exemplarily, a mounting hole is provided on the side wall of the intake pipe 350, and the second pipe section 333 is inserted into the mounting hole. The second pipe section 333 is welded to the side wall of the intake pipe 350 by welding, thereby improving the sealing performance.
