Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, for example, to a heat exchanger and a refrigeration device. Background Art

[0002] At present, when refrigeration equipment (refrigerators or freezers, etc.) is in use, the condenser located in the compressor compartment is prone to blockage. For example, the gap between the fins of the condenser is easily blocked by lint and other obstructions, resulting in poor heat exchange, affecting the refrigeration of the refrigeration equipment, and increasing power consumption.

[0003] In the related art, a condensing fan is arranged on one side of the condenser. When the condenser dissipates heat, the condensing fan sucks air to accelerate the heat dissipation of the condenser. When cleaning the condenser, the condensing fan blows air to blow out the blockages such as fluff between the fins.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Since the gap between the fins of the condenser is small, lint and other blockages are easily stuck. The condenser fan blowing method used in the related technology is used for cleaning, but the lint and other blockages are not cleaned thoroughly, resulting in poor cleaning effect.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0054] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides a heat exchanger 1. The heat exchanger 1 includes a delivery pipe 10 and a fin body 20. The interior of the delivery pipe 10 is divided into a clean flow channel and a heat exchange flow channel which are arranged side by side and independent of each other. The delivery pipe 10 is formed by a plurality of pipe sections arranged at intervals and connected in series in sequence. The fin body 20 is arranged in the interval between two adjacent pipe sections. The delivery pipe 10 is provided with a plurality of spray ports 13 connected to the clean flow channel, and the spray ports 13 correspond to the fin body 20. Among them, the heat exchange flow channel is used for the circulation of refrigerant to achieve heat exchange. The liquid in the clean flow channel can be sprayed from the spray port 13 to the surface of the fin body 20 to clean the fin body 20.

[0055] In this embodiment, the interior of the delivery pipe 10 has a cleaning flow channel and a heat exchange flow channel. Among them, the cleaning flow channel is used to transport liquid to clean the fin body 20. The heat exchange flow channel is used to transport refrigerant to achieve heat exchange. By making the cleaning flow channel and the heat exchange flow channel independent of each other, the independent operation of transporting liquid and transporting refrigerant is achieved, that is, the circulation and heat exchange process of the refrigerant is independent of the self-cleaning process of the heat exchanger 1. The cleaning flow channel and the heat exchange flow channel are arranged side by side, which can increase the contact area between the cleaning flow channel and the heat exchange flow channel. In addition, the heat exchange effect of the heat exchanger 1 is improved by exchanging heat between the liquid in the cleaning flow channel and the refrigerant in the heat exchange flow channel.

[0056] In this embodiment, multiple pipe segments are arranged at intervals, and multiple pipe segments are connected in series in sequence to form a serpentine-arranged delivery pipe 10. The serpentine-arranged delivery pipe 10 can improve the heat exchange effect. Moreover, multiple pipe segments are arranged at intervals, so that there is a gap between two adjacent pipe segments for placing the fin body 20, which further improves the heat exchange effect of the heat exchanger 1.

[0057] In this embodiment, the fin body 20 is disposed in the interval between two adjacent pipe sections, thereby increasing the contact area between the fin body 20 and the delivery pipe 10 and improving the heat exchange effect.

[0058] In this embodiment, a plurality of spray ports 13 connected to the cleaning flow channel are provided through the delivery pipe 10 , and the spray ports 13 correspond to the fin bodies 20 , so that the liquid in the cleaning flow channel can be sprayed from the spray ports 13 to the surface of the fin bodies 20 , thereby cleaning the fin bodies 20 .

[0059] Compared with the method of cleaning the condenser by blowing air with a fan in the related art, the present application cleans the fin body 20 by spraying liquid, which can effectively remove the blockages such as fluff on the fin body 20 and improve the cleaning effect.

[0060] It should be noted that the type of liquid in the cleaning flow channel is not limited, as long as it can clean the fin body 20. For example, water or a mixture of neutral detergent and water.

[0061] Optionally, combined Figure 1 , Figure 2 and Figure 4 As shown, two adjacent pipe sections are connected through a bend pipe to achieve series connection of the two adjacent pipe sections.

[0062] Optionally, combined Figure 2 , Figure 3 and Figure 5 As shown, the spray port 13 is a through hole opened in the delivery pipe 10. The through hole is connected to the clean flow channel, so that the liquid in the clean flow channel can be sprayed from the through hole to the surface of the fin body 20.

[0063] Optionally, the spray port 13 is a hole group formed by a plurality of through holes opened in the delivery pipe 10. The plurality of through holes are all connected to the cleaning flow channel, and the outlet direction of each through hole is different.

[0064] In this embodiment, the opening positions of multiple through holes are concentrated to form the spray port 13. Since the outlet directions of each through hole are different, the liquid in the cleaning flow channel can be sprayed onto the surface of the fin body 20 from multiple directions, thereby improving the cleaning effect.

[0065] Optionally, combined Figure 5As shown, the radial cross section of the delivery pipe 10 is strip-shaped, so that the delivery pipe 10 is a flat pipe extending in a serpentine shape, so as to increase the contact area between the delivery pipe 10 and the fin body 20 .

[0066] Optionally, combined Figure 5 As shown, the radial cross-sections of the cleaning flow channel and the heat exchange flow channel are both strip-shaped, so as to increase the contact area between the cleaning flow channel and the heat exchange flow channel.

[0067] In some embodiments, in combination Figure 5 As shown, there are multiple delivery pipes 10. Along the thickness direction of the heat exchanger 1, multiple delivery pipes 10 are arranged side by side in sequence. In two adjacent delivery pipes 10, the cleaning flow channel and the heat exchange flow channel are arranged crosswise.

[0068] In this embodiment, multiple delivery tubes 10 are arranged side by side in sequence along the thickness direction of the heat exchanger 1, which increases the contact area between two adjacent delivery tubes 10 and the contact area between the multiple delivery tubes 10 and the fin body 20, thereby improving the heat exchange effect.

[0069] In this embodiment, in two adjacent delivery pipes 10 , the cleaning flow channels and the heat exchange flow channels are cross-arranged, which further improves the heat exchange effect and can effectively clean the fin body 20 .

[0072] In this example, the first delivery pipe 60 and the second delivery pipe 70 are arranged side by side along the thickness direction of the heat exchanger 1. The first clean flow channel 61 and the first heat exchange flow channel 62 are arranged crosswise with the second clean flow channel 71 and the second heat exchange flow channel 72, that is, along the height direction of the heat exchanger 1, the first clean flow channel 61 and the second heat exchange flow channel 72 are at the same height position, and the second clean flow channel 71 and the first heat exchange flow channel 62 are at the same height position, so as to improve the heat exchange effect.

[0073] In this example, since the first delivery pipe 60 and the second delivery pipe 70 are arranged in a serpentine shape, the first cleaning flow channel 61 and the first heat exchange flow channel 62 are arranged crosswise with the second cleaning flow channel 71 and the second heat exchange flow channel 72, so that a spray port 13 is arranged above each fin body 20, so as to improve the heat exchange effect of the heat exchanger 1 and the self-cleaning effect at the same time.

[0081] In this embodiment, a plurality of single fins 21 are connected end to end in sequence, and the single fins 21 are obliquely arranged between two adjacent pipe sections, so that the liquid sprayed by the spray port 13 can reach the surface of the single fins 21 and improve the spraying effect.

[0082] In this embodiment, Figure 3The dashed arrow in the figure is used to indicate the spraying direction. The distance between the two single fins 21 located in front of the spraying direction of the spraying port 13 gradually decreases, so that the liquid sprayed from the spraying port 13 can splash back and forth between the two single fins 21, thereby improving the cleaning effect.
