[0037] Figure 1 For the structure of the heat exchange bin in the related art, Figure 2 For the structure of the heat exchange bin in the related art,

[0038] Referring to Figure 1 The heat exchange bin of the refrigeration equipment in the related art includes a shell 1 and a compressor 2, a condenser 6 and a fan 5 arranged in the shell 1. The fan 5 is arranged on one side of the compressor 2, and the axis of the fan 5 does not intersect the compressor 2. The compressor 2 has an exhaust pipe and a return pipe. The exhaust pipe is connected with the inlet end of the condenser 6, and the return pipe is connected with an evaporator outside the heat exchange bin to realize a refrigeration cycle. The compressor 2 compresses low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant. The high-temperature and high-pressure refrigerant flows through the condenser and the evaporator in turn, and finally returns to the compressor 2 to realize the refrigeration cycle. The condenser generates a large amount of heat during the refrigeration cycle, and the heat exchange bin needs to be cooled by the fan 5. The air flow circulation direction of the fan 5 is shown by arrows in Figure 1 The air flow from the back plate to the bottom of the front air outlet plate does not directly hit the compressor 2 on one side, but the cooling effect is poor. Due to the compact layout in the heat exchange bin, the air duct space between the back plate and the front air outlet plate is small, and a single fan 5 needs to be arranged to operate at high speed to obtain high static pressure air flow to cool the heat exchange bin. However, high-speed operation of the fan 5 will form a vortex at the front air outlet plate, resulting in generation and propagation of aerodynamic noise in the heat exchange bin, which greatly affects the user's hearing during use and standby state, and the user experience is poor.

[0039] Therefore, the embodiments of the present application provide a heat exchange bin 100 which can realize low energy consumption and noise reduction under the same air volume, and improve the user experience.

[0040] Referring to Figure 2The application provides a heat exchange bin 100, which comprises a shell 1, a compressor 2 and a first fan 3.

[0041] The shell 1 is provided with an air inlet 11 and an air outlet 12 opposite to each other, and an air duct is formed between the air inlet 11 and the air outlet 12, and the compressor 2 is arranged in the air duct. The first fan 3 is arranged in the air duct and located on the side of the compressor 2 close to the air inlet 11, and the first fan 3 is provided with a first air inlet end 3a and a first air outlet end 3b opposite to each other, the first air inlet end 3a is arranged towards the air inlet 11, and the first air outlet end 3b is arranged towards the compressor 2.

[0042] In order to clearly express the position and direction of the heat exchange bin 100 described in the embodiment, in the embodiment, the upper and lower directions can be defined according to the gravity direction when the refrigeration equipment is placed on the horizontal ground, and since the heat exchange bin 100 is arranged at the rear part of the refrigeration equipment, the front part of the refrigeration equipment is the front, and the two sides perpendicular to the front-rear direction are the left and right directions. The refrigeration equipment generally comprises a compressor 2, a condenser and an evaporator which are sequentially connected to form a circulation loop through pipelines, wherein the compressor 2 can be placed in the heat exchange bin 100, the condenser can be placed in the heat exchange bin 100 or outside the heat exchange bin 100, the evaporator is placed in a chamber, and the number of evaporators can be one, two, three or the like. The refrigeration equipment can further comprise various electric valves, reversing valves, throttling elements and the like to realize the refrigeration cycle. The compressor 2 generally has an exhaust pipe and a suction pipe, the exhaust pipe is connected with the inlet end of the condenser, and the suction pipe is connected with the outlet end of the evaporator. During refrigeration, the compressor 2 compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 2 sequentially flows through the condenser and the evaporator, and finally flows back to the compressor 2. During the refrigeration process, the compressor 2 converts mechanical energy into heat energy, which needs to be dissipated in time.

[0043] In the embodiment of the application, the heat exchange bin 100 comprises the shell 1, an air duct is formed between the air inlet 11 and the air outlet 12 opposite to each other of the shell 1, and the first fan 3 and the compressor 2 are sequentially arranged in the air duct along the left-to-right direction, and the first fan 3 drives the airflow to be introduced from the left side and blown to the right side. Compared with the heat exchange bin in the related art in which the fan drives the airflow to be blown from the rear side to the front side, the heat exchange bin 100 in the embodiment of the application adjusts the air outlet direction of the first fan 3, so that the first air outlet end 3b of the first fan 3 is arranged towards the compressor 2, and the first air inlet end 3a of the first fan 3 is arranged towards the air inlet 12.

[0044] The airflow circulation direction of the first fan 3 is as shown in Figure 2As indicated by the middle arrow, the external air is introduced from the air inlet 11 on the left side of the shell 1 to the air duct, contacts the surface of the compressor 2, and then exits from the air outlet 12 on the right side, which can improve the air inlet efficiency, reduce the airflow loss of the compressor 2 in the air outlet direction, and improve the heat dissipation efficiency of the compressor 2. Because the airflow does not collide with the shell 1 to generate vortex in the air duct, the rotation speed of the first fan 3 can be reduced under the same air volume and static pressure working condition, and the aerodynamic noise is reduced.

[0045] According to the heat exchange bin 100 provided in the embodiments of the present application, the first fan 3 and the compressor 2 are arranged in the air duct of the shell 1, the first air inlet end 3a of the first fan 3 is arranged towards the air inlet 11 of the shell 1, and the first air outlet end 3b is arranged towards the compressor 2, which can increase the contact area of the airflow and the compressor 2, improve the air inlet efficiency, reduce the airflow loss of the compressor in the air outlet direction, and improve the heat dissipation efficiency of the compressor 2; compared with a single fan in the related art, the rotation speed of the first fan 3 can be reduced under the same air volume and static pressure working condition, the noise of the airflow is reduced, low-energy-consumption noise reduction is realized, and the user experience is improved.

[0046] In some embodiments, the shell 1 includes a bottom plate 17, a side plate 14, a first air plate 15, and a second air plate 16 arranged on the bottom plate 17, the first air plate 15 and the second air plate 16 are oppositely and spacedly arranged and intersected with the side plate 14 and the bottom plate 17, the air inlet 11 is arranged on the first air plate 15, and the air outlet 12 is arranged on the second air plate 16.

[0047] As shown in Figure 2 the first air plate 15 is provided with a plurality of air inlets 11 distributed at intervals, the second air plate 16 is provided with a plurality of air outlets 12 distributed at intervals, and the first air plate 15 and the second air plate 16 are oppositely and spacedly arranged on both sides of the bottom plate 17. Compared with the air duct in the related art, the air duct space formed between the first air plate 15 and the second air plate 16 is larger, and a larger static pressure can be formed between the first fan 3 and the second fan 4, and the heat dissipation effect of the compressor 2 is better. Compared with a single fan in the related art, the air outlet efficiency of the first fan 3 can be improved under the same air volume and static pressure working condition, the airflow circulation is improved, the rotation speed of the first fan 3 is reduced, and the noise of the airflow is reduced, low-energy-consumption noise reduction is realized, and the user experience is improved.

[0048] In some embodiments, the heat exchange bin 100 further includes a second fan 4, the second fan 4 is arranged on the side of the compressor 2 away from the first fan 3, the second fan 4 has opposite second air inlet end 4a and second air outlet end 4b, the second air outlet end 4b is arranged towards the air outlet 12, and the first air outlet end 3b and the second air inlet end 4a form air convection covering the surface of the compressor 2.

[0049] As shown in Figure 2As shown, the first fan 3 and the second fan 4 are oppositely arranged in the air duct of the shell 1, and the second air outlet end 4b is arranged towards the air outlet 12, so that the air convection covering the surface of the compressor 2 is formed between the first air outlet end 3b of the first fan 3 and the second air inlet end 4a, further increasing the air inlet amount and improving the air inlet efficiency; under the same air volume and static pressure working condition, the rotation speed of the first fan 3 and the second fan 4 can be reduced to replace a single fan with high rotation speed, further reducing the aerodynamic noise. For example, the rotation speed of the single fan in the related art is 480 rpm-2400 rpm, which can be switched between different gears. However, under the same air volume and static pressure working condition, the rotation speed of the first fan 3 and the second fan 4 in the embodiment can be reduced by 40%-60%, and the corresponding aerodynamic noise can also be reduced.

[0050] Figure 3 The structure of the heat exchange bin according to an embodiment of the present application is shown from another angle.

[0051] In some embodiments, the first fan 3 and the second fan 4 are both axial flow fans, and the first height H1 between the first rotation axis S1 of the first fan 3 and the bottom plate 17 is greater than the second height H2 between the second rotation axis S2 of the second fan 4 and the bottom plate 17.

[0052] Referring to Figure 3 , the first height H1 between the first rotation axis S1 of the first fan 3 and the bottom plate 17 is greater than the second height H2 between the second rotation axis S2 of the second fan 4 and the bottom plate 17, so that there is a height difference between the first fan 3 and the second fan 4, which can reduce the back pressure and facilitate the airflow to enter the air duct. The external cold air enters the air duct from the left air inlet 11 and exits the air duct from the right air outlet 12. This side-in and side-out mode not only increases the air impingement area of the compressor 2 and improves the heat dissipation efficiency, but also reduces the noise generated by the vortex formed by the airflow impinging on the wall surface, improving the user experience.

[0053] In some embodiments, the first fan 3 and the bottom plate 17 are connected through the height increasing piece 18, and the second fan 4 is connected to the bottom plate 17. As shown in Figure 3 , the first fan 3 and the second fan 4 are similar in structure and height, saving the cost of manufacturing molds, and the height difference between the two is realized through the height increasing piece 18, which is simple in structure and reduces the manufacturing cost. In addition, the height increasing piece 18 is connected to the bottom plate 17, the first fan 3 is connected to the height increasing piece 18 and the side plate 14 respectively, improving the stability of the first fan 3. The second fan 4 is connected to the bottom plate 17 and the side plate 14 respectively, improving the stability of the second fan 4.

[0054] In some embodiments, the heat exchange chamber 100 further includes a main control board. The riser 18 is hollow inside, and the main control board is disposed inside the riser 18. The main control board is electrically connected to both the first fan 3 and the second fan 4. The main control board is used to control the speed, start and stop of the first fan 3 and the second fan 4. The main control board is disposed inside the riser 18, which can save internal space of the heat exchange chamber 100 and facilitate the connection of wires for the first fan 3, the second fan 4, etc.

[0055] Figure 4 This is a schematic diagram of the heat exchange chamber according to another embodiment of this application. Figure 5 for Figure 4 The diagram shows a perspective view of the first fan in the heat exchange chamber.

[0056] In some embodiments, the first fan 3 includes a first fan 31 and a first housing 32 covering the first fan 31. The first housing 32 is sealed to the side plate 14. A first air inlet end 3a and a first air outlet end 3b are respectively formed in the first housing 32. The heat exchange chamber 100 also includes a first condenser 6, which is disposed inside the first housing 32 and located between the first fan 31 and the first air plate 15.

[0057] See Figure 4 The heat exchange chamber 100 in this embodiment of the application and Figure 2 The heat exchange chamber 100 shown has a similar structure, but the difference is that a first condenser 6 is also provided inside the heat exchange chamber 100, and the first condenser 6 is arranged adjacent to the first fan 3.

[0058] Specifically, the first fan 3 includes a first fan 31 and a first housing 32 covering the first fan 31. The first condenser 6 is disposed inside the first housing 32 and located between the first fan 31 and the first air deflector 15. The structure is compact, and the first condenser 6 also has the function of blocking sound, achieving a noise reduction effect closer to the sound source and further improving the noise reduction effect. In this way, the high-temperature and high-pressure gaseous refrigerant discharged from the exhaust pipe of the compressor 2 flows sequentially through the first condenser 6 and the evaporator, and then returns to the suction pipe of the compressor 2. When the high-temperature and high-pressure gaseous refrigerant flows through the first condenser 6, it releases a large amount of heat, causing the temperature inside the heat exchange chamber 100 to rise, which needs to be dissipated in time by the first fan 3 and the second fan 4.

[0059] In one example, such as Figure 5As shown, the first casing 32 of the first fan 3 can include a first top wall and a first side wall intersectingly arranged around the periphery of the first fan 31, the first top wall is arranged parallel to the bottom plate 17, and the first side wall is arranged parallel to the side plate 14, one end of the first top wall away from the first side wall is sealingly connected with the side plate 14, and one end of the first side wall away from the first top wall is connected with the raised piece 18. In this way, when the airflow passes through the first fan 3, it can only pass through from inside the first casing 32, but cannot pass through from other positions outside the first casing 32, thereby enhancing the noise reduction effect. In another example, the first casing 32 can also include a rectangular frame arranged around the periphery of the first fan 31, and two intersecting walls in the rectangular frame can be respectively connected with the side plate 14 and the raised piece 18. In another example, the first casing 32 can also include three walls arranged around the periphery of the first fan 31, and the gap between two walls is sealingly connected with the side plate 14.

[0060] In addition, a soundproof layer can be arranged between the first casing 32 and the side plate 14. The soundproof layer can be a sealing material such as sealant, foam, silicone, rubber, etc. The soundproof layer can be pre-installed on the side plate 14 or fixed on the first casing 32, so as to ensure that the airflow can only reach the other side through the first casing 32, thereby further enhancing the noise reduction effect.

[0061] In some embodiments, the second fan 4 includes a second fan 41 and a second casing 42 covering the second fan 41, the second casing 42 is sealingly connected with the side plate 14, and the second air inlet end 4a and the second air outlet end 4b are formed in the second casing 42; the heat exchange bin further includes a second condenser 7, the second condenser 7 is arranged in the second casing 42 and located on the side of the second fan 41 away from the second air plate 16, and the second condenser 7 is in communication with the first condenser 6 through a pipeline.

[0062] Referring to Figure 4 , the heat exchange bin 100 further includes a second condenser 7, the second condenser 7 is in communication with the first condenser 6 through a pipeline, thereby improving the heat exchange efficiency. In this way, the high-temperature and high-pressure gaseous refrigerant discharged from the exhaust pipe of the compressor 2 flows through the first condenser 6, the second condenser 7 and the evaporator in sequence, and then returns to the suction pipe of the compressor 2. The high-temperature and high-pressure gaseous refrigerant releases a large amount of heat when flowing through the first condenser 6 and the second condenser 7, resulting in an increase in the temperature in the heat exchange bin 100, which needs to be cooled in time. The second condenser 6 is arranged in the second casing 32 of the second fan 4 and located on the side of the second fan 41 away from the second air plate 16, thereby having a compact structure, and the second condenser 7 also has the function of blocking sound, thereby achieving a noise reduction effect at a position closer to the sound source, and further improving the noise reduction effect.

[0063] The structure of the second fan 4 is similar to that of the first fan 3. In one example, the second cover 42 can include a second top wall and a second side wall intersectingly arranged around the periphery of the second fan 41, the second top wall is arranged parallel to the bottom plate 17, and the second side wall is arranged parallel to the side plate 14. One end of the second top wall away from the second side wall is sealingly connected to the side plate 14, and one end of the second side wall away from the second top wall is connected to the bottom plate 17. In this way, when the air flow passes through the second fan 4, it can only pass from inside the second cover 42 and cannot pass from other positions outside the second cover 42, thereby enhancing the noise reduction effect. In another example, the second cover 42 can also include a rectangular frame arranged around the periphery of the second fan 41, and two intersecting walls in the rectangular frame can be connected to the side plate 14 and the bottom plate 17, respectively. In another example, the second cover 42 can also include three walls arranged around the periphery of the second fan 41, and the gap between two walls is sealingly connected to the side plate 14.

[0064] In some embodiments, the first distance L1 between the first air outlet end 3b of the first fan 3 and the compressor 2 is greater than the second distance L2 between the second air inlet end 4a of the second fan 4 and the compressor 2.

[0065] Referring to Figure 2 , when the air flow enters the first cover 32 from the air inlet 11 on the left side of the shell 1, the starting noise generated is relatively large. The first distance L1 between the first air outlet end 3b of the first fan 3 and the compressor 2 is greater than the second distance L2 between the second air inlet end 4a of the second fan 4 and the compressor 2. This can prolong the propagation path of the sound and weaken the energy of the sound, so that the sound after passing through the compressor 2 continues to disperse outward through the air outlet 12, thereby reducing the noise of the heat exchange bin 100 without affecting the normal exhaust and heat dissipation in the heat exchange bin 100.

In the present embodiment, as shown in Figure 5 , the refrigeration equipment 1000 is a refrigerator, and the heat exchange bin 100 can be located at the bottom of the refrigerator.

[0069] According to the refrigeration equipment 1000 provided in the embodiments of the present application, the heat exchange bin 100 of the embodiments of the present application can increase the contact area of the airflow and the compressor 2, improve the air inlet efficiency, reduce the airflow loss of the compressor 2 in the air outlet direction, and improve the heat dissipation efficiency of the compressor 2; compared with a single fan in the related art, the rotating speed of the first fan 3 can be reduced under the same air volume and static pressure working condition, the noise of the airflow is reduced, low-energy-consumption noise reduction is achieved, and the user experience is improved.
