Heat exchange humidifying device and air conditioner

Abstract

The utility model is applicable to the technical field of air conditioners, and provides a heat exchange and humidification device and an air conditioner, and the heat exchange and humidification device comprises an evaporator and a wet film assembly. The air conditioner comprises the heat exchange and humidification device of any one of the above items. Due to the fact that the wet film assembly is arranged on the inner side of the groove-shaped structure, when the wet film assembly drips water, water leaking out of the wet film assembly only drips into the evaporator and finally drips into a water receiving structure of the evaporator, and therefore the water floating out of the wet film assembly can be prevented from leaking to other devices outside the evaporator, such as an electric control device. Meanwhile, the wet film assembly is arranged on the inner side of the groove-shaped structure of the evaporator and can be separated from the filtering device arranged on the outer side of the evaporator, the situation that the filtering device needs to be detached when the wet film assembly is maintained is avoided, and therefore the wet film assembly can be more conveniently maintained.

Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a heat exchange and humidification device and an air conditioner. Background Technology

[0002] During air conditioning use, to prevent the indoor air from becoming too dry, a humidifier is usually installed inside the air conditioner to increase the humidity. Humidifiers can employ methods such as wet film humidification, electrode humidification, or ultrasonic humidification. Wet film humidification works by delivering water to a sprayer at the top of the humidifier. The sprayer ensures that the water is evenly distributed onto the wet film material, and under gravity, the water permeates downwards along the material, forming a uniform water film. When dry air passes through the wet film material, the dry air comes into contact with the moist surface of the film, thus humidifying the air. However, existing heat exchange humidification devices often suffer from problems such as susceptibility to water leakage and inconvenient installation and maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a heat exchange and humidification device and an air conditioner, which aims to solve the technical problems of easy water leakage and inconvenient installation and maintenance of existing heat exchange and humidification devices.

[0004] This utility model is implemented as follows: Firstly, it provides a heat exchange and humidification device, comprising:

[0005] An evaporator having two inclined working sections arranged at an included angle, the two working sections forming a trough-shaped structure, each working section having an air outlet surface and an air inlet surface, the air outlet surface being located on the inner side of the trough-shaped structure and the air inlet surface being located on the outer side of the trough-shaped structure; and

[0006] A wet film assembly is disposed inside the trough structure and close to the air outlet surface to increase the humidity of the gas passing through the wet film assembly.

[0007] In an optional embodiment, a first water receiving element is provided on the inner side of the trough structure, and the lower end of the wet membrane assembly is located inside the first water receiving element. The first water receiving element is used to support the wet membrane assembly and contain water overflowing from the wet membrane assembly.

[0008] In an optional embodiment, the bottom of the evaporator is provided with a second water receiving component, and the bottom of the first water receiving component is provided with a drain pipe. The drain pipe is connected to the first water receiving component and is used to guide the water in the first water receiving component to the second water receiving component.

[0009] In an optional embodiment, the evaporator is provided with a mounting position for mounting the wet film assembly, the wet film assembly being movably inserted into the mounting position.

[0010] In one optional embodiment, a first sliding member is provided inside the first water receiving part, a second sliding member is provided in the mounting position, the lower end of the wet film assembly slides against the first sliding member, and the side wall of the wet film assembly slides against the second sliding member.

[0011] In an optional embodiment, the evaporator is provided with an installation stop, the installation stop having a clearance structure for the passage of the wet film assembly, the wet film assembly being inserted into the installation position through the clearance structure, and the wet film assembly also having an elastic buckle, the elastic buckle contacting the installation stop to fix the wet film assembly during installation, and the elastic buckle disengaging from the installation stop when the wet film assembly is disassembled.

[0012] In an optional embodiment, a limiting member is provided on the first sliding member and / or the second sliding member, the limiting member and the mounting stop are spaced apart along the sliding direction of the wet film assembly, and the limiting member is used to limit the wet film assembly.

[0013] In an alternative embodiment, the wet film assembly is provided with a pull handle located on the side of the wet film assembly away from the limiting member.

[0014] In one optional embodiment, the wet membrane assembly includes a support frame, a spray structure, and a wet membrane portion. The wet membrane portion is located within the support frame, and the spray structure is located between the top of the wet membrane portion and the support frame. The spray structure is used to communicate with an external water supply pipeline and spray water onto the wet membrane portion to wet it.

[0015] In a second aspect, an air conditioner is provided, including a main housing and the heat exchange and humidification device described in any of the above claims. A partition baffle is provided inside the main housing to divide the main housing into a return air chamber and an air outlet chamber. The evaporator is located in the return air chamber. The evaporator and the partition baffle are arranged to form a leeward chamber, and the wet film assembly is located in the leeward chamber.

[0016] The technical advantages of this invention compared to existing technologies are as follows: An evaporator with a trough-shaped structure consisting of two inclined working sections arranged at an angle is used, with the wet film assembly positioned inside the trough-shaped structure. During operation, air enters the working section from the air inlet side of the trough-shaped structure, exchanges heat with the cooling medium inside, and then exits from the air outlet side of the trough-shaped structure, entering the wet film assembly for humidification before being discharged. Compared to existing technologies, because the wet film assembly is positioned inside the trough-shaped structure, when water drift occurs, the water leaking from the wet film assembly will only drip into the interior of the evaporator and eventually into the evaporator's water collection structure. This prevents water from leaking from the wet film assembly onto other external components, such as electrical control devices. Furthermore, positioning the wet film assembly inside the trough-shaped structure of the evaporator allows it to be separated from the filter device located on the outside of the evaporator, avoiding the need to disassemble the filter device during maintenance of the wet film assembly, thus making maintenance of the wet film assembly more convenient.

[0017] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figures 1 to 5 As shown, in a first aspect of this utility model embodiment, a heat exchange and humidification device is provided, comprising an evaporator 1 and a wet film assembly 2. The evaporator 1 has two working sections 11 arranged at an included angle, forming a trough-shaped structure. Each working section 11 has an air outlet surface and an air inlet surface. The air outlet surface is located on the inner side 12 of the trough-shaped structure, and the air inlet surface is located on the outer side 13 of the trough-shaped structure. The wet film assembly 2 is disposed on the inner side 12 of the trough-shaped structure and close to the air outlet surface, allowing gas to pass through the wet film assembly 2 and increasing the humidity of the gas passing through the wet film assembly 2.

[0034] Specifically, evaporator 1 refers to a device used to transfer heat from one fluid to another. Its basic principle is based on at least one of the three heat transfer methods: conduction, convection, and radiation. The two working parts 11 of evaporator 1 are arranged at an angle and form an upward-opening groove-shaped structure. The groove-shaped structure refers to a recessed structure with a certain depth. The groove-shaped structure formed by the two working parts 11 can be "V"-shaped. The two working parts 11 are two heat exchangers that make up evaporator 1. The two heat exchangers form an integral V-shaped heat exchanger at an angle, and the bottom and sides of the V-shaped heat exchanger are sealed with sheet metal to form the groove-shaped evaporator 1. The opening of the groove-shaped evaporator 1 can face upwards or downwards, depending on the air outlet direction requirements of the air conditioner application scenario. The outer side 13 of the evaporator 1 corresponding to the working part 11 is usually the air inlet surface for airflow into the working part 11, and the inner side 12 of the evaporator 1 corresponding to the working part 11 is usually the air outlet surface for airflow out of the working part 11.

[0035] The wet membrane module 2 refers to a component or part that increases air humidity by allowing air to pass through a moistened membrane. The wet membrane module 2 is generally a plate-like structure. Wet membrane humidification primarily utilizes the natural evaporation of water. It is typically made of plant fibers (such as fiberglass, paper fibers, etc.) or other absorbent materials. When air flows over the surface of the wet membrane, due to the partial pressure difference between the water vapor in the wet membrane and the surrounding air, water evaporates from the surface of the wet membrane into the air, thereby increasing the air humidity.

[0036] The heat exchange and humidification device provided in this embodiment of the invention comprises an evaporator 1 with two inclined working sections 11 arranged at an angle, forming a trough-shaped structure, and a wet film assembly 2 disposed on the inner side 12 of the trough-shaped structure. During operation, air enters the working section 11 from the outer side 13 of the evaporator 1 via the air inlet surface. After heat exchange with the cooling medium within the working section 11, air exits from the air outlet surface of the working section 11 on the inner side 12 of the trough-shaped structure, then enters the interior of the wet film assembly 2, where it is humidified before being discharged. Compared to the prior art, because the wet film assembly 2 is disposed on the inner side 12 of the trough-shaped structure, when water drift occurs in the wet film assembly 2, the water leaking from the wet film assembly 2 will only drip into the interior of the evaporator 1 and eventually into the water receiving structure of the evaporator 1. This prevents water drifting from the wet film assembly 2 from leaking onto other external components of the evaporator 1, such as electrical control devices. Meanwhile, the wet film assembly 2 is set inside the groove structure 12 of the evaporator 1, which can be set separately from the filter device set outside the evaporator 1 13, so that the filter device needs to be disassembled when the wet film assembly 2 is maintained, thus making the maintenance of the wet film assembly 2 more convenient.

[0037] Furthermore, by placing the wet film assembly 2 on the inner side 12 of the evaporator 1, the air passing through the wet film assembly 2 is filtered by a filter device located on the outer side 13 of the evaporator 1. This prevents the accumulation of a large amount of dust on the wet film assembly 2 after prolonged use, thus avoiding its humidification effect and frequent replacement due to dust accumulation. Simultaneously, placing the wet film assembly 2 on the inner side 12 of the evaporator 1 also reduces the overall space occupied, making more efficient use of the air conditioner's internal space.

[0038] In one embodiment, see Figure 2The inner side 12 of the trough-shaped structure is provided with a first water receiving component 3, and the lower end of the wet film assembly 2 is located inside the first water receiving component 3. The first water receiving component 3 is used to support the wet film assembly 2 and to contain water overflowing from the wet film assembly 2. Specifically, the first water receiving component 3 refers to a component with a certain containing space. The first water receiving component 3 can be disc-shaped, block-shaped, or a combination of various shapes. The trough-shaped structure, i.e., the evaporator 1, is provided with the first water receiving component 3. After the wet film assembly 2 is installed, the lower end of the wet film assembly 2 is located inside the first water receiving component 3. The first water receiving component 3 supports the bottom of the wet film assembly 2, making the installation of the wet film assembly 2 more stable and secure. In addition, when there is too much water in the wet film assembly 2 and it overflows from the bottom of the wet film assembly 2, the first water receiving component 3 can contain the water overflowing from the wet film assembly 2 to prevent water leakage, making the heat exchange and humidification device safer to use.

[0039] Based on the aforementioned features of the first water receiving component 3, please refer to Figure 2 The evaporator 1 has a second water receiving component 4 at its bottom, and a drain pipe 9 at the bottom of the first water receiving component 3. The drain pipe 9 is connected to the first water receiving component 3 and is used to guide the water in the first water receiving component 3 to the second water receiving component 4. Specifically, the second water receiving component 4 refers to a component with a certain amount of accommodating space. The second water receiving component 4 can be disc-shaped, block-shaped, or a combination of various shapes. By providing the second water receiving component 4 at the bottom of the evaporator 1, the condensate generated by the evaporator 1 during operation can be accommodated. The drain pipe 9 refers to a pipe structure with a certain length. By connecting one end of the drain pipe 9 to the bottom of the first water receiving component 3 and directly connecting the other end of the drain pipe 9 to the second water receiving component 4, or by having the other end of the drain pipe 9 open above the second water receiving component 4, the water in the first water receiving component 3 can be guided to the second water receiving component 4 through the drain pipe 9. Since the volume of the second water receiving part 4 is larger than that of the first water receiving part 3, by guiding the water in the first water receiving part 3 to the second water receiving part 4, it is possible to prevent excessive water from overflowing and leaking into the interior of the air conditioner, thereby making the heat exchange and humidification device safer and more reliable to use.

[0040] In one specific embodiment, please refer to Figure 2 Both the first water receiving component 3 and the second water receiving component 4 are water receiving trays. Specifically, a water receiving tray refers to a component with a certain depth. Water receiving trays can be manufactured from sheet metal through sheet metal work or stamping, making the processing and manufacturing of the first water receiving component 3 and the second water receiving component 4 more convenient.

[0041] In one embodiment, see Figure 1The evaporator 1 is provided with a mounting position for installing the wet film assembly 2, and the wet film assembly 2 is movably inserted into the mounting position. Specifically, the mounting position refers to a virtual area. When the wet film assembly 2 is in the mounting position, the bottom of the wet film assembly 2 abuts against the first water receiving part 3, and the side wall of the first water receiving part 3 leans against and abuts against the inner side 12 of the evaporator 1. This makes the installation of the wet film assembly 2 more convenient and stable. At the same time, the wet film assembly 2 can be movably inserted into the mounting position, which can be installed into the mounting position by pulling out or inserting it during installation and removal. This reduces the space required for the installation and removal of the wet film assembly 2, making the maintenance of the wet film assembly 2 more convenient.

[0042] In one embodiment, see Figure 4 A first sliding member 5 is provided inside the first water receiving component 3, and a second sliding member 6 is provided at the installation position. The lower end of the wet film assembly 2 slides against the first sliding member 5, and the side wall of the wet film assembly 2 slides against the second sliding member 6. Specifically, the first sliding member 5 refers to a component with a certain volume. The first sliding member 5 can be strip-shaped, plate-shaped, or block-shaped, or it can be composed of a combination of various shapes. The first sliding member 5 can be installed into the first water receiving component 3 by welding, snap-fitting, or fastener connection. The second sliding member 6 refers to a component with a certain volume. The second sliding member 6 can be strip-shaped, plate-shaped, or block-shaped, or it can be composed of a combination of various shapes. The second sliding member 6 can be installed into the inner side 12 of the evaporator 1 by welding, snap-fitting, or fastener connection. By providing a first sliding member 5 inside the first water receiving part 3, and a second sliding member 6 inside the evaporator 1 12, and by having the lower end of the wet film assembly 2 slide against the first sliding member 5 and the side wall of the wet film assembly 2 slide against the second sliding member 6, it is easier to insert the wet film assembly 2 into the installation position, thereby making the disassembly and installation of the wet film assembly 2 more convenient and improving the convenience of maintenance.

[0043] It should be noted that by providing a first sliding member 5 inside the first water receiving component 3, the first sliding member 5 can slide and abut against the wet film assembly 2 while also supporting the wet film assembly 2, thereby creating a certain distance between the wet film assembly 2 and the first water receiving component 3, which can prevent the presence of the wet film assembly 2 from affecting the volume of the first water receiving component 3.

[0044] In an optional embodiment, please refer to Figure 4 Multiple ventilation holes can also be provided on the second sliding member 6. Specifically, the ventilation holes refer to through-hole structures provided through the second sliding member 6. By providing ventilation holes on the second sliding member 6, air can pass through the ventilation holes, thereby avoiding the second sliding member 6 from obstructing the airflow, thus making the airflow at the inner side 12 of the evaporator 1 smoother.

[0045] In one embodiment, see Figure 3 The evaporator 1 is equipped with an installation stop 7, which has a clearance structure 71 for the passage of the wet film assembly 2. The installation stop is a sheet metal part that seals and encapsulates the side of a V-shaped heat exchanger composed of two working parts 11. The clearance structure 71 can be a clearance hole for the wet film assembly on the sheet metal part. Thus, the clearance structure 71 allows the wet film assembly to be inserted and installed inside the evaporator 1. The wet film assembly 2 is inserted into the installation position through the clearance structure 71. The wet film assembly 2 is also equipped with an elastic latch 24. When the wet film assembly 2 is installed, the elastic latch 24 contacts the installation stop 7 to fix the wet film assembly 2. When the wet film assembly 2 is disassembled, the elastic latch 24 disengages from the installation stop 7. Specifically, the installation stop 7 refers to a component with a certain volume, which can be plate-shaped, block-shaped, or a combination of various shapes. The clearance structure 71 refers to a clearance structure for avoiding other objects, which can be a clearance hole, clearance groove, or clearance opening 711, etc. The elastic latch 24 is a component used to fix the position of an object relative to other parts. The elastic latch 24 typically consists of a movable part and an elastic element. By providing an installation stop 7 and a clearance structure 71 on the evaporator 1, the wet film assembly 2 is inserted into the installation position through the clearance structure 71. Simultaneously, the wet film assembly 2 is also provided with the elastic latch 24. After the wet film assembly 2 is installed in the installation position, the movable part of the elastic latch 24 can extend under the action of the elastic element and contact the installation stop 7, thus fixing the wet film assembly 2 relative to the installation stop 7. When the wet film assembly 2 needs to be disassembled, the movable part of the elastic latch 24 can be pushed inward, causing the movable part to compress the elastic element and retract into the elastic latch 24 until it disengages from the installation stop 7, making the disassembly and installation of the wet film assembly 2 more convenient.

[0046] In one embodiment, see Figure 3 There are two elastic buckles 24. Both elastic buckles 24 are located on the outside of the wet membrane assembly 2. The two elastic buckles 24 are located at the bottom and top of the same side of the wet membrane assembly 2, which can make the wet membrane assembly 2 more secure and stable when fixed.

[0047] In one specific embodiment, please refer to Figure 3 The mounting baffle 7 includes a mounting baffle plate disposed between the two working parts 11 of the evaporator 1. The clearance structure 71 includes a clearance opening 711 disposed on the mounting baffle plate. Specifically, the mounting baffle plate refers to a plate-shaped component with a certain area, and the clearance opening 711 refers to an opening structure with a certain area. The clearance opening 711 can be made on the mounting baffle plate by stamping.

[0048] In one embodiment, see Figure 4A limiting element 8 is provided on the first sliding member 5 and / or the second sliding member 6. The limiting element 8 and the installation stop 7 are spaced apart along the sliding direction of the wet film assembly 2. The limiting element 8 is used to limit the position of the wet film assembly 2. Specifically, the limiting element 8 refers to a component with a certain volume. The limiting element 8 can be plate-shaped, block-shaped, or a combination of various shapes. The limiting element 8 is provided on the first sliding member 5 and / or the second sliding member 6 in the following situations: Situation 1, the limiting element 8 is provided on the first sliding member 5; Situation 2, the limiting element 8 is provided on the second sliding member 6; Situation 3, both the first sliding member 5 and the second sliding member 6 are provided with limiting elements 8. The limiting element 8 can be connected to the first sliding member 5 or the second sliding member 6 by snap-fit, welding, or fastener connection. By setting the limiting element 8 during the insertion process of the wet film assembly 2, the insertion depth of the wet film assembly 2 can be limited, thereby making the installation position of the wet film assembly 2 more accurate and the maintenance of the wet film assembly 2 more convenient.

[0049] In one embodiment, see Figure 4 The wet membrane assembly 2 is provided with a pull handle 25, which is located on the side of the wet membrane assembly 2 away from the limiting member 8. Specifically, the pull handle 25 is a component of a certain size. The pull handle 25 can be installed on the side of the wet membrane assembly 2 away from the limiting member 8 by welding, snap-fitting, or fastening. By providing a pull handle 25 on the wet membrane assembly 2, space can be provided for hand gripping during the installation and removal of the wet membrane assembly 2, thereby making the installation and removal of the wet membrane assembly 2 more convenient.

[0050] In one embodiment, see Figure 5The wet membrane assembly 2 includes a support frame 21, a spray structure 22, and a wet membrane section 23. The wet membrane section 23 is located within the support frame 21, and the spray structure 22 is located between the top of the wet membrane section 23 and the support frame 21. The spray structure 22 is used to connect to an external water supply pipeline and spray water onto the wet membrane section 23 to wet it. Specifically, the support frame 21 refers to a frame structure with a certain volume. To facilitate the installation of the wet membrane assembly 2, the support frame 21 is usually rectangular. The wet membrane section 23 refers to a wet membrane material made of plant fibers (such as glass fiber, paper fiber, etc.) or other absorbent materials. When air flows across the surface of the wet membrane, due to the water vapor partial pressure difference between the water in the wet membrane and the surrounding air, the water will evaporate from the surface of the wet membrane into the air. The spray structure 22 is a structure that evenly sprays water onto other components. The spray structure 22 can be a pipe structure with multiple spray holes evenly arranged on the pipe. During the operation of the wet film assembly 2, an external water source injects water into the spray structure 22 through a pipeline. The spray structure 22 sprays water evenly onto the wet film section 23, thus wetting the wet film section 23. When air flows through the wet film section 23, due to the water vapor partial pressure difference between the water in the wet film and the surrounding air, the water evaporates from the surface of the wet film into the air, thereby increasing the humidity of the air.

[0051] Secondly, please refer to Figure 6 An air conditioner is provided, including a main housing 100 and a heat exchange and humidification device 300 as described above. A partition baffle 200 is provided inside the main housing 100, dividing the main housing 100 into a return air chamber 500 and an outlet air chamber 700. An evaporator 1 is located in the return air chamber 500, and the evaporator 1 and the partition baffle 200 form a leeward air chamber 600, with a wet film assembly 2 located within the leeward air chamber 600. A fan device 400 may also be provided in the outlet air chamber 700.

[0052] When the air conditioner is operating, external water is first supplied to the wet film assembly 2 through the water pipe and the water inlet control solenoid valve. The wet film section 23 is moistened by the spray structure 22. The fan device 400 drives the air drawn in from the return air vent to flow sequentially into the filter, heat exchanger, and wet film assembly 2. As the air passes through the wet film assembly 2, the water evaporates and carries away the moisture on the wet film section 23. The air is then expelled from the air outlet by the fan device 400, thus humidifying the air. Excess water dripping from the wet film assembly 2 is drained into the second water receiving part 4 through the drain pipe 9 on the first water receiving part 3. Furthermore, since the heat exchanger uses hydrophilic aluminum foil, water droplets flying out from the wet film assembly 2 will fall onto the fins and flow into the second water receiving part 4 along the heat exchanger fins at a certain angle, thereby preventing water leakage from the air conditioner.

[0053] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
