Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning heat exchangers, in particular to a heat exchanger component and an air-conditioning indoor unit. Background Art

[0002] The heat exchanger is one of the core components of the air conditioner indoor unit. It mainly plays the role of transferring heat, allowing the air conditioning system to achieve cooling or heating functions. It enables the air conditioning system to effectively transfer heat according to the temperature difference between indoor and outdoor and user needs to achieve the purpose of cooling or heating. The heat exchanger in the air conditioner indoor unit is mainly based on the physical property changes of the refrigerant and the principles of thermodynamics. During the refrigeration process, the refrigerant absorbs heat from the evaporator and evaporates to form low-pressure steam, which is then compressed into high-pressure steam by the compressor. When flowing through the condenser, it releases heat and condenses into high-pressure liquid. After passing through the throttling device, the pressure and temperature of the refrigerant are reduced and it enters the evaporator again to complete the refrigeration cycle. The heating process is similar to the refrigeration process, except that the heat transfer direction is opposite;

[0003] When the air conditioning system is running, air will flow inside the system, causing dust in the air to accumulate on the surface of the heat exchanger, resulting in a decrease in heat exchange effect. When cleaning the dust on the surface of the heat exchanger, the air conditioning casing needs to be disassembled, which is a more troublesome operation.

[0004] To solve the above problems, the present application proposes a heat exchanger assembly and an air conditioner indoor unit. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a heat exchanger assembly and an air conditioner indoor unit.

[0006] The utility model provides a heat exchanger assembly, comprising a heat exchanger body;

[0007] An air duct is installed on the top of the heat exchanger body, an air passage is provided in the air duct, and an air inlet connected to the air passage is provided at one end of the air duct. A tubular dust blowing member arranged toward the surface of the heat exchanger body is connected to one side of the air duct, and a pneumatic member is rotatably connected in the air passage.

[0008] A tubular guide member is installed at the bottom of the heat exchanger body and is arranged toward the surface thereof. The other end of the air duct is connected to a ventilation pipe that is in communication with the tubular guide member.

[0009] Preferably, the tubular dust-blowing component includes a dust-blowing pipe, which is installed on one side of the air duct. The bottom of the dust-blowing pipe is connected to a plurality of dust-blowing nozzles arranged at intervals and facing the surface of the heat exchanger body. The dust-blowing pipe is connected to a plurality of conducting pipes arranged at intervals and inserted into the air duct.

[0010] Preferably, the pneumatic part includes a plurality of rotating rods, and the plurality of rotating rods are arranged at intervals in the air passage and correspond to a plurality of conducting pipes.

[0012] An air conditioner indoor unit comprises an air conditioner casing and a heat exchanger assembly, wherein the heat exchanger assembly is installed in the air conditioner casing.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] Through the provision of the tubular dust-blowing member, the pneumatic member and the tubular guide member, when air circulates through the heat exchanger body in the air-conditioning casing, a part of the air can enter the air passage along the air inlet opened at one end of the air duct. When the airflow passes through the surface of the pneumatic member, it can drive it to rotate. When the pneumatic member rotates, the wind can be guided into the tubular dust-blowing member, which can blow air on the surface of the heat exchanger body to reduce dust adhesion to the surface of the heat exchanger body. The wind entering the air passage can be guided into the tubular guide member along the ventilation duct, and the dust blown off the surface of the heat exchanger body can enter the tubular guide member. Under the action of the tubular guide member, the dust is guided out of the air-conditioning casing.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0020] like Figure 1-3 As shown, a heat exchanger assembly proposed by the present invention includes a heat exchanger body 1;

[0021] In this embodiment, an air duct 2 is mounted on the top of the heat exchanger body 1. An air passage is defined within the air duct 2, and an air inlet 3 is provided at one end of the air duct 2, communicating with the air passage. A tubular dust blower 4, positioned toward the surface of the heat exchanger body 1, is connected to one side of the air duct 2. The tubular dust blower 4 includes a dust blowing pipe 41 mounted on one side of the air duct 2. The bottom of the dust blowing pipe 41 is connected to a plurality of spaced dust blowing nozzles 42 positioned toward the surface of the heat exchanger body 1. The dust blowing pipe 41 is connected to a plurality of spaced dust blowing nozzles 42, which are positioned toward the surface of the heat exchanger body 1. The dust blowing pipe 41 is connected to a plurality of spaced conduction pipes 8, which are inserted into the air passage.

[0022] In this embodiment, a pneumatic element 5 is rotatably connected within the air passage. The pneumatic element 5 comprises a plurality of rotating rods 51, which are spaced apart within the air passage and correspond to the plurality of conducting tubes 8. One end of each rotating rod 51 is rotatably connected to the inner wall of the air passage 2, and the other ends of each rotating rod 51 extend into the plurality of conducting tubes 8. Axial fan blades 52 are mounted on both ends of each rotating rod 51, with two axial fan blades 52 on each rotating rod 51 positioned within the air passage and within the plurality of conducting tubes 8, respectively.

[0023] In this embodiment, a tubular guide 6 is mounted on the bottom of the heat exchanger body 1, facing the surface thereof. The other end of the air duct 2 is connected to a ventilation pipe 7, which is in communication with the tubular guide 6. The tubular guide 6 includes an exhaust pipe 61, which is mounted on the bottom of the heat exchanger body 1 and has a strip-shaped opening 62 facing the surface of the heat exchanger body 1. The end of the ventilation pipe 7, facing away from the air duct 2, is in communication with one end of the exhaust pipe 61.

[0024] An air conditioner indoor unit comprises an air conditioner casing 9 and a heat exchanger assembly, wherein the heat exchanger assembly is installed in the air conditioner casing 9.

[0025] It should be noted that: when in use, when air circulates through the heat exchanger body 1 in the air conditioner housing 9, a portion of the air can enter the air passage along the air inlet 3 opened at one end of the air duct 2. When the airflow passes through the surface of the axial flow fan blade 52 in the air passage, it can drive the rotating rod 51 and the axial flow fan blade 52 located in the guide tube 8 to rotate at the same time. When the axial flow fan blade 52 located in the guide tube 8 rotates, the wind can be guided into the dust blowing pipe 41, and the heat exchanger can be blown by the dust blowing nozzle 42 at the bottom of the dust blowing pipe 41. Air is blown on the surface of the heat exchanger body 1 to reduce dust adhesion to the surface of the heat exchanger body 1. The wind entering the air passage can be guided to the exhaust pipe 61 along the ventilation pipe 7. The dust blown off the surface of the heat exchanger body 1 can enter into it along the strip opening 62 opened on the exhaust pipe 61. Under the action of the airflow, the dust can be guided out along the exhaust pipe 61. This structure can reduce the adhesion of dust on the surface of the heat exchanger body 1, keep the surface of the heat exchanger body 1 clean and tidy, and ensure the heat exchange effect of the heat exchanger body 1.
