Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air conditioning water heat exchanger. Background Technology

[0002] An air conditioning water heat exchanger is a key component in an air conditioning system for heat exchange. It uses water as a cooling medium, and a fan draws hot indoor air into the heat exchanger to exchange heat with the cold water flowing through it, thereby lowering the indoor temperature. For example, a heat exchanger proposed in application number "CN201780005081.6" includes: a first heat transfer tube (21); a first manifold section (52); a second heat transfer tube (23); a second manifold section (53); and multiple connecting passages (61, 71) to allow the first manifold section (21) to... 52) The connection to the second manifold (53) is such that one end is connected to the first manifold (52) and the other end is connected to the second manifold (53). The connection position of one end of each connecting path (61, 71) relative to the first manifold (52) is set at the same height position among the connecting paths (61, 71), and the connection position of the other end of each connecting path (61, 71) relative to the second manifold (53) is set at different height positions among the connecting paths (61, 71).

[0003] However, in the above technical solutions, during long-term use of the heat exchanger, as the liquid continuously flows inside the pipes, scale will be generated in the water due to high temperature. However, since this scale cannot be filtered, it often adheres to the inner wall of the pipes. Over time, the scale will block the inside of the water pipes, affecting the normal use of the water heat exchanger. Therefore, we propose an air conditioning water heat exchanger to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide an air conditioning water heat exchanger that solves the problem that when the exchanger is used for a long time, as the liquid flows continuously inside the pipe, scale will be generated in the water due to high temperature. However, since this scale cannot be filtered, it will often adhere to the inner wall of the pipe, and over time, the scale will block the inside of the water pipe, affecting the normal use of the water heat exchanger.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An air conditioning water heat exchanger includes a housing, inside which are installed a plurality of fins. A heat-conducting pipe is installed through the housing and the fins. An inlet pipe is installed at the upper end of the heat-conducting pipe, and an outlet pipe is installed at the lower end of the heat-conducting pipe. A filter mechanism is installed at the lower end of the outlet pipe, and a connecting pipe is installed at one end of the filter mechanism. The filter mechanism includes a filter barrel, the upper end of which is engaged with the outlet pipe. A drain pipe is installed through the lower end of the filter barrel, and one end of the drain pipe is connected to the connecting pipe. A support frame is installed at the lower end of the filter barrel, and a plurality of filter layers are engaged at the upper end of the filter barrel, with the filter layers adhering to the support frame.

[0007] Preferably, a first limiting ring is installed at the lower end of the outlet pipe and the end of the connecting pipe near the filter barrel, and a second limiting ring is installed at the upper end of the filter barrel and the end of the drain pipe near the connecting pipe, with the first and second limiting rings fitting together.

[0008] Preferably, a sealing ring is installed between the first limiting ring and the second limiting ring, and a connecting cap is fitted on the outer side of the liquid outlet pipe and the connecting pipe. The inner wall of the connecting cap is provided with an internal thread, and the outer sides of the first limiting ring and the second limiting ring are respectively provided with external threads. The connecting cap is installed on the outer side of the first limiting ring and the second limiting ring by thread engagement.

[0009] Preferably, the filter barrel has guide grooves on both sides of the upper end, guide blocks are installed at both ends of the guide grooves, and the upper ends of the guide blocks are in contact with the liquid outlet pipe. A fixing frame is fixedly installed between the guide blocks, and a rotating shaft is movably installed inside the fixing frame.

[0010] Preferably, an impeller is installed at the upper end of the rotating shaft, and the impeller and the liquid outlet pipe are parallel vertically.

[0011] Preferably, a connecting frame is installed at the lower end of the rotating shaft. The connecting frame is movably located inside the filter barrel and is in contact with the filter layer. Several scrapers are installed inside the connecting frame and are in contact with the filter layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, when the water flows inside the heat-conducting pipe, it will enter the filter bucket through the liquid outlet pipe. Then, the scale in the water flow can be filtered through several filter layers inside the filter bucket, thereby preventing the scale from flowing into the various pipes inside the air conditioner along with the water flow, improving the overall service life, and also preventing the blockage of the pipes, so that the air conditioner can work more stably.

[0014] (2) In this utility model, when the water flows into the interior of the filter bucket along the outlet pipe, the water flow will control the impeller to rotate through the impact. Then the impeller can drive the rotating shaft and the connecting frame to rotate, thereby allowing the connecting frame to drive the scraper to rotate, so that the scraper pushes the scale on the surface of the filter layer, avoiding the situation where the scale accumulates in one place for a long time and causes blockage, reducing the filtration effect of the filter layer on the water flow.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 5As shown in the figure, this utility model embodiment proposes an air conditioning water heat exchanger, including a shell 1, a plurality of fins 4 installed inside the shell 1, a heat conduction pipe 3 installed through the shell 1 and the fins 4, an inlet pipe 2 installed at the upper end of the heat conduction pipe 3, an outlet pipe 5 installed at the lower end of the heat conduction pipe 3, a filter mechanism 6 installed at the lower end of the outlet pipe 5, a connecting pipe 7 installed at one end of the filter mechanism 6, the filter mechanism 6 including a filter barrel 601, the upper end of the filter barrel 601 being engaged with the outlet pipe 5, a drain pipe 604 being installed through the lower end of the filter barrel 601, one end of the drain pipe 604 being connected to the connecting pipe 7, a support frame 602 being installed at the lower end of the filter barrel 601, and a plurality of filter layers 603 being engaged with the upper end of the filter barrel 601, and the filter layers 603 being in close contact with the support frame 602.

[0023] like Figure 5 As shown, in another embodiment of this utility model, a first limiting ring 605 is installed at the lower end of the outlet pipe 5 and the end of the connecting pipe 7 near the filter tank 601, and a second limiting ring 606 is installed at the upper end of the filter tank 601 and the end of the drain pipe 604 near the connecting pipe 7. The first limiting ring 605 and the second limiting ring 606 are close to each other and fit together. A sealing ring 607 is installed between the first limiting ring 605 and the second limiting ring 606. A connecting cover 608 is sleeved on the outer side of the outlet pipe 5 and the connecting pipe 7. The inner wall of the connecting cover 608 is provided with internal threads, and the outer sides of the first limiting ring 605 and the second limiting ring 606 are provided with external threads. The connecting cover 608 is installed on the first limiting ring 605 and the second limiting ring 606 by thread engagement. Outside the limiting ring 606, guide grooves 609 are provided on both sides of the upper end of the filter barrel 601. Guide blocks 610 are installed at both ends of the guide grooves 609. The upper end of the guide blocks 610 is in contact with the liquid outlet pipe 5. A fixing frame 611 is fixedly installed between the guide blocks 610. A rotating shaft 612 is movably installed inside the fixing frame 611. An impeller 613 is installed at the upper end of the rotating shaft 612. The impeller 613 and the liquid outlet pipe 5 are parallel vertically. A connecting frame 614 is installed at the lower end of the rotating shaft 612. The connecting frame 614 is movably located inside the filter barrel 601 and is in contact with the filter layer 603. Several scrapers 615 are installed inside the connecting frame 614 and are in contact with the filter layer 603.

[0024] Water flows into the heat pipe 3 through the inlet pipe 2. The water then exchanges heat with the fins 4 inside the heat pipe 3. After heat exchange, the water flows into the filter tank 601 through the outlet pipe 5. The downward flow of water drives the impeller 613 to rotate, allowing the filter layer 603 to filter out scale and other impurities in the water. The filtered water then flows through the drain pipe 604 and the connecting pipe 7 to other components in the air conditioner. At the same time, the impeller 613 drives the rotating shaft 612 to rotate, which in turn controls the rotating bracket 614 and the scraper 615 to rotate. The scraper 615 then pushes the impurities on the surface of the filter layer 603, preventing impurities from accumulating in one place and causing blockage.

[0025] The connecting cover 608, together with the first limiting ring 605 and the second limiting ring 606, facilitates the user to disassemble and clean the filter canister 601, thus extending the overall service life.

[0026] The guide groove 609 and guide block 610 are used to limit the rotation shaft 612, so that the rotation shaft 612 can stably drive the impeller 613 and the connecting frame 614 to work inside the filter barrel 601, and at the same time, it is convenient for users to clean the rotation shaft 612, impeller 613 and filter layer 603 later.

[0027] The working principle of this type of air conditioning water heat exchanger:

[0028] In use, water first enters the heat pipe 3 through the inlet pipe 2. Then, the water inside the heat pipe 3 works with the fins 4 to exchange heat. After heat exchange, the water flows through the outlet pipe 5 into the filter tank 601. The downward flow of water drives the impeller 613 to rotate, allowing the filter layer 603 to filter scale and other impurities from the water. The filtered water then flows through the drain pipe 604 and the connecting pipe 7 to other components in the air conditioner. At the same time, the impeller 613 drives the rotating shaft 612 to rotate, which in turn controls the rotating bracket 614 and the scraper 615 to move the scraper 615 away from the impurities on the surface of the filter layer 603, preventing impurities from accumulating in one place and causing blockage.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
