Description

Heat exchangers and indoor air conditioning units Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a heat exchanger and an indoor air conditioning unit. Background Technology

[0002] With the development of the times and the advancement of technology, the development trend of air conditioning is gradually moving towards diversification and higher efficiency. In traditional air conditioning, when air passes through the heat exchanger in cooling mode, some water vapor condenses into water, flowing down the heat exchanger and drip tray, and then draining away through the drain pipe. This can cause the moisture content in the air to continuously decrease, making the indoor environment drier and reducing comfort. As the seasons change, the moisture content in the air constantly fluctuates. Especially in autumn and winter, the lower moisture content in the air can also lead to a poorer experience and lower comfort for people's skin and senses. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a heat exchanger and an air conditioner indoor unit that overcomes or at least partially solves the above problems, and can solve the problem of poor comfort in existing air conditioners. By uniformly distributing water, the humidification uniformity and continuity are improved, and the humidification effect is increased, thereby improving the user experience and comfort.

[0004] Specifically, the present invention provides a heat exchanger. The heat exchanger includes a plurality of fins, which are arranged in parallel at intervals to form at least one fin gap;

[0005] At least one nozzle blade is disposed within the fin gap;

[0006] The nozzle plate has a transmission space inside, and the nozzle plate has a water outlet hole communicating with the transmission space, so that water in the transmission space flows out from the water outlet hole to the outside of the nozzle plate.

[0007] Optionally, the nozzle blades and the fins are arranged alternately in sequence, and adjacent nozzle blades and fins are spaced apart.

[0008] Optionally, each of the nozzle segments is provided with a water outlet at its top.

[0009] Optionally, the water outlet is elongated and extends along the length of the top end of the nozzle plate. There is one water outlet, or two water outlets are arranged side by side.

[0010] Optionally, the water outlet holes are arranged in one row or two parallel rows; each row has multiple water outlet holes, and the multiple water outlet holes are arranged along the length direction of the top end of the nozzle plate.

[0011] Optionally, the water outlet holes are arranged in two rows, with one row of water outlet holes alternating with the other row.

[0012] Optionally, the heat exchanger further includes a water supply pipe;

[0013] The lower end of the nozzle plate is connected to the water supply pipe so that the water supply pipe can transmit water to the nozzle plate;

[0014] The water supply pipe is set horizontally;

[0015] The cross-sectional area of ​​the water supply pipe gradually decreases along the direction of water flow within the pipe.

[0016] Optionally, the tip of the nozzle blade is tapered, gradually decreasing in size from bottom to top.

[0017] The height of the nozzle tip is lower than the height of the fin tip.

[0018] Furthermore, the present invention also provides an indoor air conditioning unit. The indoor air conditioning unit includes any of the heat exchangers described above.

[0019] Optionally, the heat exchanger further includes a water storage device for supplying water to the transmission space of the nozzle plates; and

[0020] A water pump, used to drive water from the water storage device into the transmission space of the nozzle plate;

[0021] The water storage device is a water receiving tray, which is located below the heat exchanger.

[0022] This invention discloses a heat exchanger comprising a nozzle plate and fins. The nozzle plate has a hollow structure with an internal transmission space. Water outlet holes are formed on the nozzle plate, connecting the internal transmission space and the outside of the nozzle plate. When water flows within the transmission space of the nozzle plate, the water can flow through the outlet holes to the outside of the nozzle plate. The water flowing to the outside of the nozzle plate flows downwards along the outer wall of the nozzle plate or is sprayed onto the fins arranged parallel to the nozzle plate, thus ensuring more uniform spraying of the water after it exits the transmission space. Under the action of the heat exchanger, the water exiting the transmission space evaporates over a large area and is blown outwards by the air conditioner's fan, humidifying the external environment. The dry external environment becomes humid, improving the user's experience and comfort.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] Figure 1 is a schematic structural diagram of a heat exchanger according to an embodiment of the present invention. As shown in Figure 1, and referring to Figures 2 to 4, an embodiment of the present invention provides a heat exchanger 100. The heat exchanger 100 includes a plurality of fins 120, which are arranged in parallel and spaced apart to form at least one fin gap. One or more nozzle plates 110 are disposed within the at least one fin gap. The nozzle plate 110 has a transmission space, and the nozzle plate 110 has a water outlet hole 111 communicating with the transmission space, so that water in the transmission space flows out from the water outlet hole 111 to the outside of the nozzle plate 110.

[0034] The specific working process is as follows: At least one nozzle plate 110 is provided between the fins 120. The nozzle plate 110 has a hollow structure and an internal transmission space. A water outlet hole 111 is opened on the nozzle plate 110, which connects the transmission space inside the nozzle plate 110 and the outside of the nozzle plate 110. When water flows in the transmission space inside the nozzle plate 110, the water in the transmission space can flow to the outside of the nozzle plate 110 through the water outlet hole 111. The water flowing to the outside of the nozzle plate 110 flows downward along the outer wall of the nozzle plate 110, or is sprayed onto the fins 120 arranged parallel to the nozzle plate 110, so that the water in the transmission space is sprayed more evenly after flowing out of the transmission space. Under the action of heat exchanger 100, the water flowing out of the transmission space evaporates over the large area of ​​heat exchanger 100. Driven by the air conditioner's fan, the airflow passes through the gaps between fins 120 and nozzle 110, and / or the gaps between fins 120 and nozzle 110, and / or the gaps between nozzle 110 and nozzle 110, and is then blown towards the outside of the air conditioner, humidifying the external environment. The dry external environment becomes humid, improving the user's experience and comfort.

[0035] In some embodiments of the present invention, nozzle blades 110 and fins 120 are arranged alternately in sequence, and adjacent nozzle blades 110 and fins 120 are arranged at intervals.

[0036] In this embodiment, nozzle plates 110 and fins 120 are arranged alternately. That is, each nozzle plate 110 has fins 120 arranged on both sides adjacent to it, and each fin 120 has nozzle plates 110 arranged on both sides adjacent to it, with gaps between adjacent nozzle plates 110 and fins 120. This arrangement makes the water flowing out of the internal transmission space of the nozzle plate 110 more evenly distributed on the heat exchanger 100, thus improving the water uniformity effect.

[0037] In some embodiments of the present invention, each nozzle fin 110 is provided with a water outlet 111 at its top end. In this embodiment, the water outlet 111 is provided at the top end of the nozzle fin 110. Water is transmitted from the lower end of the nozzle fin 110 to the top end, and the water transmitted to the top end is sprayed out from the water outlet 111. When the water flows out of the water outlet 111, depending on the pressure it receives, it may flow directly down the outer wall of the water spray pipe, or it may be sprayed onto the adjacent fins 120 due to the horizontal velocity it has when leaving the top end of the water spray pipe.

[0038] In this embodiment, a water outlet hole 111 is provided at the top of the nozzle plate 110. The water flowing out from the water outlet hole 111 can flow from the top of the heat exchanger 100 to the bottom of the heat exchanger 100, which increases the flow area of ​​the humidifying water and is beneficial to improving the water uniformity and humidification effect.

[0039] In some embodiments of the present invention, the water outlet 111 is elongated and extends along the length direction of the top end of the nozzle 110, and there is one water outlet 111.

[0040] In this embodiment, only one water outlet 111 is provided. The length direction of the water outlet 111 is consistent with the length direction of the nozzle plate 110, which facilitates water outlet 111 and water flowing downward along the outer wall.

[0041] Of course, in some embodiments of the present invention, the water outlet 111 may also be elongated, with the water outlet 111 extending along the length of the top end of the nozzle 110, and two water outlets 111 arranged side by side.

[0042] In some embodiments of the present invention, the water outlet holes 111 are arranged in a row, with multiple water outlet holes 111 in each row, and the multiple water outlet holes 111 are arranged along the length direction of the top end of the nozzle plate 110. In this embodiment, multiple water outlet holes 111 are provided, which results in more uniform water distribution compared to a single elongated water outlet hole 111.

[0043] Of course, in some embodiments of the present invention, the water outlet holes 111 are arranged in two parallel rows. Each row has multiple water outlet holes 111, and the multiple water outlet holes 111 are arranged along the length direction of the top end of the nozzle plate 110.

[0044] In some embodiments of the present invention, the water outlet holes 111 are arranged in two rows, with one row of water outlet holes 111 and the other row of water outlet holes 111 arranged alternately.

[0045] In some embodiments of the present invention, the heat exchanger 100 further includes a water supply pipe 200. The lower end of the nozzle 110 is connected to the water supply pipe 200. In this embodiment, the lower end of the nozzle 110 is connected to the water supply pipe 200, and water can flow through the water supply pipe 200 to be transported to the nozzle 110.

[0046] In some embodiments of the present invention, the water supply pipe 200 is inclined downwards along the water flow direction. In this embodiment, the downward inclination facilitates the flow of water in the water supply pipe 200 to the downstream end. Of course, in some embodiments of the present invention, the water supply pipe 200 may also be inclined upwards along the water flow direction.

[0047] In some embodiments of the present invention, the water supply pipe 200 is horizontally arranged. In this embodiment, the horizontal arrangement of the water supply pipe 200 is relatively inclined, which makes better use of space and avoids the phenomenon of water shortage at the higher end.

[0048] In some embodiments of the present invention, the cross-sectional area of ​​the water supply pipe 200 gradually decreases along the direction of water flow within the water supply pipe 200. In this embodiment, because the water flowing inside the water supply pipe 200 during the water supply process will be injected into the nozzle plate 110, the gradual decrease in the cross-sectional area of ​​the water supply pipe 200 along the direction of water flow within the water supply pipe 200 can avoid insufficient water supply power to the nozzle plate 110 at the downstream end of the water supply pipe 200.

[0049] In some embodiments of the present invention, the top of the nozzle blade 110 is tapered, gradually decreasing in size from bottom to top.

[0050] In this embodiment, the nozzle tip is tapered, which facilitates the flow of water from the outlet hole 111 down the outer wall of the nozzle plate 110.

[0051] In some embodiments of the present invention, the height of the top end of the nozzle blade 110 is lower than the height of the top end of the fin 120. In this embodiment, the lower height of the top end of the nozzle blade 110 compared to the top end of the fin 120 effectively saves space.

[0052] In some embodiments of the present invention, the height of the top end of the nozzle 110 is higher than the height of the top end of the fin 120. In this embodiment, the height of the top end of the nozzle 110 being higher than the height of the top end of the fin 120 can improve the spraying effect of the second water outlet 111, which is beneficial to improving the water uniformity effect.

[0053] Furthermore, the present invention also provides an air conditioner indoor unit. The air conditioner indoor unit includes the heat exchanger 100 in any of the above embodiments.

[0054] In some embodiments of the present invention, the indoor unit of the air conditioner includes a water storage device 400. In this embodiment, the water storage device 400 is used to supply water to the transmission space of the nozzle 110 to ensure the continuity of water supply.

[0055] In some embodiments of the present invention, the indoor unit of the air conditioner further includes a water pump 300. The water pump 300 is used to drive water from the water storage device 400 into the transmission space of the nozzle plate 110. In this embodiment, the water pump 300 provides continuous power for the transmission of water.

[0056] In some embodiments of the present invention, the water storage device 400 is a water receiving tray, which is disposed below the heat exchanger 100.

[0057] In this embodiment, a drip tray is positioned below the heat exchanger 100 to collect any unevaporated water from the heat exchanger 100. This prevents water flowing from the heat exchanger 100 from entering the room and damaging electrical components, thus improving the safety performance of the indoor air conditioning unit.

[0058] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
