Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of evaporators, in particular to an evaporator supporting assembly, an evaporator assembly and an air conditioner. BACKGROUND

[0002] Some evaporative compressor units have very high compactness, such as inter-row air conditioners, which have a super-thin design structure in which an evaporator, a compressor, a fan assembly, an electrical control box, a throttling element, a humidifier, a return air filter, auxiliary components and related pipeline connecting elements are arranged. Such inter-row air conditioners are usually applied to high heat flux density data rooms and have the function of constant temperature and humidity air conditioning, and are usually operated in a refrigeration mode all year round, so that condensate water is often generated in the evaporator. In order to ensure the constant humidity in the data room and avoid water accumulation, it is necessary to ensure that the condensate water is promptly removed, thereby preventing safety accidents.

[0003] In the common structural arrangement design scheme of the inter-row air conditioner, the evaporator is vertically placed on the water pan, and the condensate water is collected on the water pan by gravity and is removed through the drain pipe. In order to improve the structural stability of the tall evaporator, metal pieces are usually added to the upper and lower parts of the evaporator and are connected to the metal pieces on the left and right sides of the evaporator. The water passage metal piece is arranged at the bottom of the evaporator and is connected and fixed with the left and right side plates. The water passage metal piece is directly placed on the water pan, and its height will affect the normal flow of the condensate water on both sides of the evaporator, that is, the condensate water on the water pan on the air outlet side must reach a certain height to overflow the water passage and enter the water pan on the air return side, and then be removed from the drain pipe.

[0004] In order to solve this water accumulation problem, the water passage has a plurality of notches on the side surface to facilitate the free flow of condensate water on both sides of the evaporator. However, when the evaporator is operated in a dry operating condition, that is, no condensate water is generated, or the height of the condensate water does not reach the height of the notch, the notch will cause part of the return air to directly reach the air outlet without being treated by the evaporator, which is commonly known as air leakage, which is a problem to be solved.

[0005] Since the metal piece arranged at the bottom of the evaporator in the prior art blocks the normal flow of condensate water, and the notch causes air leakage, which affects the heat exchange performance of the evaporator, the present application researches and designs an evaporator supporting assembly, an evaporator assembly and an air conditioner.

DETAILED DESCRIPTION

[0045] As Figures 1 to 5 shown, the present application provides a support assembly for an evaporator, which comprises:

[0046] a support member 3 (preferably a sheet metal member) and a wind blocking structure 4, the support member being arranged between the bottom of the evaporator 1 and the water pan 2 for supporting the evaporator 1, the support member 3 comprising a top plate 31, a first side plate 32 and a second side plate 33, the top plate 31 being located at the upper portion of the support member 3 and supporting the bottom of the evaporator 1, the first side plate 32 being connected to the top plate 31 and extending downwardly, and the second side plate 33 being connected to the top plate 31 and extending downwardly, so that the top plate 31, the first side plate 32 and the second side plate 33 enclose a water passing groove 5 with an opening facing downwardly;

[0047] And a first slot 321 is formed on the first side plate 32 in a way that penetrates through two opposite plate surfaces of the first side plate 32, and a second slot 331 is formed on the second side plate 33 in a way that penetrates through two opposite plate surfaces of the second side plate 33, the first side plate 32 is close to the return air side 6 of the evaporator relative to the second side plate 33, and the second side plate 33 is close to the air outlet side 7 of the evaporator relative to the first side plate 32, so that the condensed water can flow from the air outlet side 7, the second slot 331, the water passing groove 5, the first slot 321 to the return air side 6;

[0048] And the air blocking structure 4 is arranged in the water passing groove 5, and / or the air blocking structure 4 is arranged on the plate surface of the first side plate 32 away from the second side plate 33, and / or the air blocking structure 4 is arranged on the plate surface of the second side plate 33 facing the first side plate 32, so as to effectively block the air of the first slot 321 and / or the second slot 331.

[0049] The application can form a downwardly opening water passing groove structure by arranging a support component between the evaporator and the water pan to be a structure including a top plate, a first side plate and a second side plate, and a first slot and a second slot are respectively formed on the first side plate and the second side plate, so that the first slot and the second slot are respectively communicated with the water passing groove, so that the condensed water of the air outlet side flows into the water pan of the return air side through the second slot, the water passing groove and the first slot, so as to effectively drain water, and at the same time, the air blocking structure arranged on the inside of the water passing groove and / or the plate surface of the first side plate facing the return air side and / or the plate surface of the second side plate facing the first side plate can effectively block the air of the return air side from flowing into the air outlet side through the first slot, the water passing groove and the second slot, effectively form air blocking, ensure that the air of the return air side exchanges heat through the evaporator as much as possible, prevent the situation that air leakage cannot effectively exchange heat, can prevent air leakage while allowing the drainage of condensed water, prevent the reduction of the heat exchange efficiency of the evaporator, and effectively improve the heat exchange efficiency and heat exchange performance of the evaporator.

[0050] The application has the beneficial effects as follows: when the evaporator operates in a dry working condition without condensed water or with insufficient condensed water, the air blocking floating strip of low density can block the upper space of the slot of the water passing groove, avoid part of the return air from passing through the gap of the slot, and thus prevent air leakage. The application effectively solves the problem of air leakage of the slot of the water passing groove of the evaporator at the bottom of the evaporating compressor unit.

[0051] The water passing groove metal part of the present application is internally provided with a low-density wind blocking floating strip, which can float on the water surface and block the upper gap of the groove, preventing air leakage; or a low-density wind blocking floating strip is arranged on the outer side of the water passing groove on the return air side, or the wind blocking floating strip is arranged on the inner side of the water passing groove on the air outlet side, which is opened under the flow impact of the water flow, realizing the free flow of condensation water while blocking part of the return air from passing through the upper gap of the groove. That is, the wind blocking floating strip of the present application has three installation modes, one is placed in the middle, and two and three are attached to the side, and the state of the floating strip is determined by gravity and buoyancy when attached.

[0052] Embodiment 1, as Figure 3-3b In some embodiments, when the wind blocking structure 4 is arranged in the water passing groove 5, the wind blocking structure 4 comprises a first wind blocking structure 41, the height of the upper end surface of the first wind blocking structure 41 is higher than the height of the upper end surface of the first groove 321 and / or the second groove 331, and the density of the first wind blocking structure 41 is less than the density of water. This is the preferred structure of the wind blocking structure of Embodiment 1 of the present application, that is, the first wind blocking structure is arranged in the water passing groove, and the first wind blocking structure can effectively block the air flowing from the first groove by the height of the upper end surface of the first wind blocking structure being higher than the height of the upper end surface of the first groove and / or the second groove, and the density of the first wind blocking structure being less than the density of water can cause the water entering the water passing groove from the second groove to lift the first wind blocking structure, so that the first wind blocking structure floats up without affecting the flow of water, thereby ensuring the normal flow of condensation water while effectively blocking the wind, preventing the wind from directly passing through the water passing groove from the return air side to the air outlet side, and improving the refrigeration and heat exchange effect of the evaporator.

[0053] In some embodiments, when there is no water in the water passing groove 5, the height of the upper end surface of the first wind blocking structure 41 is higher than the height of the upper end surface of the second groove 331; and the first wind blocking structure 41 can move in the water passing groove 5, and when water flows into the water passing groove 5, the first wind blocking structure 4 can float on the water surface. This is a further preferred structure of the first wind blocking structure of the present application, that is, when there is no water in the water passing groove, the first wind blocking structure falls to the bottom water collecting disc due to gravity, at this time, the first wind blocking structure is arranged such that the height of the upper end surface is higher than the height of the upper end of the second groove, which can maximally prevent the wind from passing through the water passing groove from the second groove into the air outlet side, further improving the effect of preventing air leakage.

[0054] In some embodiments, the first wind-blocking structure 41 is a cuboid wind-blocking float, which is arranged in a gap between the plate surface of the first side plate 32 facing the second side plate 33, a gap between the plate surface of the second side plate 33 facing the first side plate 32, and a gap between the plate surface of the top plate 31 facing downward. This is a further preferred structure of the first wind-blocking structure of the present application, i.e., a cuboid wind-blocking float structure, which is arranged in a gap between the first side plate, the second side plate, and the top plate, so that the float structure can move freely in the water channel, especially can be driven upward by the water in the water channel, and can prevent the water flow from being hindered while blocking the wind.

[0055] In some embodiments, when there is no water in the water channel 5, the height of the upper end surface of the first wind-blocking structure 41 is lower than the height of the plate surface of the top plate 31 facing downward. It is further preferred that the upper end surface of the first wind-blocking structure of the present application is lower than the height of the lower end surface of the top plate when there is no water in the water channel, which can further effectively ensure that the first wind-blocking structure can move freely in the water channel, and can accommodate the condensed water to pass through while blocking the wind.

[0056] In some embodiments, when there is no water in the water channel 5, the height of the upper end surface of the first wind-blocking structure 41 is lower than the height of the plate surface of the top plate 31 facing downward. It is further preferred that the upper end surface of the first wind-blocking structure of the present application is lower than the height of the lower end surface of the top plate when there is no water in the water channel, which can further effectively ensure that the first wind-blocking structure can move freely in the water channel, and can accommodate the condensed water to pass through while blocking the wind. Figure 3-3b As shown in FIG. 1, a low-density wind-blocking float is inserted into the hollow position inside the water channel, and the wind-blocking float has sufficient gaps with the inner surfaces of the water channel, so that the wind-blocking float can move freely under the blowing of the flowing air and under the buoyancy of the condensed water; the height of the wind-blocking float is higher than the height of the slot and smaller than the total height of the water channel, and the wind-blocking float can block all the slots in any case. When there is no condensed water, the wind-blocking float falls under the influence of gravity and contacts the water pan, at this time the flowing air blows the wind-blocking float to move to the air outlet side, and then blocks the second slot on the air outlet side, thereby preventing the air leakage phenomenon. As the refrigeration operation time increases, the condensed water gradually increases, and the condensed water on the water pan increases, and the wind-blocking float floats up, but the wind-blocking float still blocks the second slot under the high wind pressure of the return air, at this time the condensed water enters the bottom of the wind-blocking float from the second slot on the air outlet side, then passes through the first slot on the opposite return air side, and then reaches the water pan on the return air side. This paragraph describes in detail the water passing and air blocking principle of the "water channel + wind-blocking float", and the embodiment is simple and reliable, has low processing and production cost, and has the disadvantage of inconvenient after-sales maintenance.

[0057] As shown in FIG. 2, a low-density wind-blocking float is inserted into the hollow position inside the water channel, and the wind-blocking float has sufficient gaps with the inner surfaces of the water channel, so that the wind-blocking float can move freely under the blowing of the flowing air and under the buoyancy of the condensed water; the height of the wind-blocking float is higher than the height of the slot and smaller than the total height of the water channel, and the wind-blocking float can block all the slots in any case. When there is no condensed water, the wind-blocking float falls under the influence of gravity and contacts the water pan, at this time the flowing air blows the wind-blocking float to move to the air outlet side, and then blocks the second slot on the air outlet side, thereby preventing the air leakage phenomenon. As the refrigeration operation time increases, the condensed water gradually increases, and the condensed water on the water pan increases, and the wind-blocking float floats up, but the wind-blocking float still blocks the second slot under the high wind pressure of the return air, at this time the condensed water enters the bottom of the wind-blocking float from the second slot on the air outlet side, then passes through the first slot on the opposite return air side, and then reaches the water pan on the return air side. This paragraph describes in detail the water passing and air blocking principle of the "water channel + wind-blocking float", and the embodiment is simple and reliable, has low processing and production cost, and has the disadvantage of inconvenient after-sales maintenance. Figure 4-4dIn some embodiments, when the wind blocking structure 4 is arranged on the surface of the first side plate 32 away from the second side plate 33, the wind blocking structure 4 comprises a second wind blocking structure 42, which is opposite to the first slot 321, and can be pushed away by water in the water passing groove 5 when the water passes through the first slot 321, and can be abutted to the surface of the first side plate 32 by air on the side of the first side plate 32 away from the water passing groove 5 when the air blows to the first slot 321, so as to close the first slot 321.

[0058] This is the preferred structure of the wind blocking structure of the embodiment 2 of the present application, that is, the second wind blocking structure is arranged on the surface of the first side plate facing the return air side and opposite to the first slot, so that the water in the water passing groove can freely push away the second wind blocking structure to form a free flow when passing through the first slot, and the air flowing to the first slot from the return air side provides a pushing force to abut the second wind blocking structure to the surface of the first side plate, so that the second wind blocking structure effectively blocks the air, forming a wind blocking at the first slot while allowing the condensed water to freely pass through the first slot, improving the effect of preventing air leakage.

[0059] In some embodiments, the upper end of the second wind blocking structure 42 is connected to the surface of the first side plate 32 away from the second side plate 33, and the upper end of the second wind blocking structure 42 is above the first slot 321, and the lower end of the second wind blocking structure 42 is a free end, and when the second wind blocking structure 42 is in a vertical state, the second wind blocking structure 42 blocks the first slot 321. This is a further preferred structure of the second wind blocking structure of the embodiment 2 of the present application, that is, the upper end of the second wind blocking structure is fixed to the surface of the first side plate, and the lower end is a free end, which can be pushed by water to move the lower end to open the first slot, and can be pushed by air to abut the lower end to the surface of the first side plate to block the air while allowing the water to freely pass through.

[0060] In some embodiments, the upper end of the second wind blocking structure 42 is fixed to the surface of the first side plate 32 away from the second side plate 33 by bonding, screwing or riveting, etc. (screwing is a connection method that uses the mutual engagement force between threads to connect two or more parts together, which usually includes bolt and nut connection, screw connection, etc., the same below), and the lower end of the second wind blocking structure 42 can rotate around the upper end of the second wind blocking structure 42 towards the direction away from or close to the first side plate 32. The second wind blocking structure of the present application is further preferred in that the upper end is fixed by bonding, screwing, riveting, etc., and the lower end rotates around the upper end as a pivot, which can realize that only water can push the lower end to move to open the first slot, and the air closes the first slot, achieving the effect of blocking the air while allowing the water to freely pass through.

[0061] Example 2, as Figure 4-4d As shown, in order to solve Figure 3 Regarding the maintenance problem when the windbreak float in Embodiment 1 malfunctions, this technical solution fixes the windbreak float to the outer side plate of the water passage. A preferred solution is to fix the windbreak float to the side plate of the water passage on the return air side. A secondary solution is to place the windbreak float on the inner side of the water passage on the air outlet side. This secondary solution has the same disadvantages as Embodiment 1, namely, inconvenience for after-sales maintenance. Therefore, Embodiment 2 mainly describes... Figure 4 The preferred arrangement shown is as follows: the upper part of the low-density windbreak float is fixed to the upper outer surface of the water passage on the return air side, for example, by adhesive or screws; the lower part of the windbreak float is designed to be free, allowing it to be pushed away from the passage opening by the buoyancy and flow impact of the condensate, thus enabling free flow of the condensate. To prevent some return air from entering through the openings on both sides, flexible waterproof plastic films (not shown here) are designed on both sides of the windbreak float. Embodiment two is more complex in production and processing, but simple and convenient in after-sales maintenance.

[0062] Example 3, as Figure 5 In some embodiments, when the windbreak structure 4 is disposed on the surface of the second side plate 33 facing the first side plate 32, the windbreak structure 4 includes a third windbreak structure 43, which is positioned opposite to the second slot 331. When water in the air outlet 7 passes through the second slot 331, it can push the third windbreak structure 43 open. When air in the water passage 5 blows toward the second slot 331, it can abut the third windbreak structure 43 against the surface of the second side plate 33, thereby closing the second slot 331.

[0063] This is a preferred structural form of the windbreak structure in Embodiment 3 of the present invention. The third windbreak structure is disposed on the surface of the second side plate facing the first side plate and opposite to the second slot. This allows water in the water passage to freely push aside the third windbreak structure and form free flow when passing through the second slot. The air flowing from the water passage to the second slot provides thrust to push the third windbreak structure against the surface of the first side plate. This allows the third windbreak structure to effectively block the air, forming a windbreak at the second slot while allowing condensate water to freely pass through the second slot, thus improving the effect of preventing air leakage.

[0064] In some embodiments, the upper end of the third windbreak structure 43 is connected to the surface of the second side plate 33 facing the first side plate 32, the upper end of the third windbreak structure 43 is located above the second slot 331, and the lower end of the third windbreak structure 43 is a free end. When the third windbreak structure 43 is in a vertical state, the third windbreak structure 43 blocks the second slot 331.

[0065] This is a further preferred structure of the third wind blocking structure of Embodiment 3 of the present application, i.e. the upper end of the third wind blocking structure is fixed to the plate surface of the second side plate, the lower end is a free end, which can be pushed by water to move the lower end to open the second slot, and can be pushed by air to abut against the plate surface of the second side plate to block the wind while allowing water to pass freely.

[0066] In some embodiments, the upper end of the third wind blocking structure 43 is fixed to the plate surface of the second side plate 33 facing the first side plate 32 by means of bonding, screwing or riveting, etc., and the lower end of the third wind blocking structure 43 can rotate around the upper end of the third wind blocking structure 43 towards the first side plate 32. The third wind blocking structure of the present application is further preferred in that the upper end is fixed by means of bonding, screwing, riveting, etc., and the lower end rotates around the upper end as a pivot, which can achieve the effect of being pushed by water to move the lower end to open the second slot, and being pushed by air to close the second slot, thereby blocking the wind while allowing water to pass freely.

[0067] In some embodiments, when the wind blocking structure 4 comprises a second wind blocking structure 42, the second wind blocking structure 42 is in the form of a wind blocking floating strip; and when the wind blocking structure 4 comprises a third wind blocking structure 43, the third wind blocking structure 43 is in the form of a wind blocking floating strip. This is a preferred structure of the second and third wind blocking structures of the present application, both of which are in the form of a wind blocking floating strip, which can achieve the effect of being freely pushed by water to open the first or second slot, and being pushed by air to abut against the first or second slot to close the first or second slot.

[0068] In some embodiments, the support member 3 further comprises a first bottom plate 34 and a second bottom plate 35, one end of the first bottom plate 34 is connected to the lower end of the first side plate 32, and the other end extends towards the second side plate 33; and one end of the second bottom plate 35 is connected to the lower end of the second side plate 33, and the other end extends towards the first side plate 32.

[0069] The first slot 321 is arranged on the first side plate 32 at a position where it is connected to the first bottom plate 34, or the first slot 321 is arranged on the first side plate 32 close to the first bottom plate 34 relative to the top end of the first side plate 32, or the first slot 321 extends from the first side plate 32 to the bottom of the first bottom plate 34; and the second slot 331 is arranged on the second side plate 33 at a position where it is connected to the second bottom plate 35, or the second slot 331 is arranged on the second side plate 33 close to the second bottom plate 35 relative to the top end of the second side plate 33, or the second slot 331 extends from the second side plate 33 to the bottom of the second bottom plate 35.

[0070] The first slot extending to the bottom of the first base plate preferably means that the first slot cuts the first base plate, such that the first base plate is divided into two parts, and the gap between the two parts of the first base plate can be used for water flow, that is, the first slot also extends from the side of the first base plate away from the second base plate to the side facing the second base plate; the second slot extending to the bottom of the second base plate preferably means that the second slot cuts the second base plate, such that the second base plate is divided into two parts, and the gap between the two parts of the second base plate can be used for water flow, that is, the second slot also extends from the side of the second base plate away from the first base plate to the side facing the first base plate.

[0071] The supporting component of the present invention further preferably includes a first base plate and a second base plate, which can be used to connect with the water receiving tray at the bottom and increase the contact area, thereby improving the supporting effect on the evaporator above the supporting component and making the support more stable; and the first slot and the second slot are both set to be connected to or close to the base plate so that the slot position is set as low as possible, so that the condensate can pass through the slot to the maximum extent, and the air below is relatively thin, thus further reducing the probability of air leakage, improving the efficiency of wind blocking and the effect of allowing water to pass through, and further improving the heat exchange performance of the evaporator.

[0072] In some embodiments, the top plate 31 has a cuboid structure and matches the shape of the bottom of the evaporator 1. The top plate 31 includes a first side and a second side, which are two opposing long sides. The first side plate is connected to the first side of the top plate and extends downward, and the second side plate is connected to the second side of the top plate and extends downward.

[0073] The first base plate 34 extends horizontally from the point where it connects with the lower end of the first side plate 32, and the length of the first base plate 34 extending horizontally is less than half the length of the wide side of the top plate 31. The second base plate 35 extends horizontally from the point where it connects with the lower end of the second side plate 33, and the length of the second base plate 35 extending horizontally is less than half the length of the wide side of the top plate 31. The first base plate 34 and the second base plate 35 are not connected.

[0074] Both the first base plate 34 and the second base plate 35 are connected to the water receiving tray 2 below the evaporator 1.

[0075] This is a further preferred structural form of the top plate, first side plate, second side plate, first bottom plate and second bottom plate of the present invention, which can form a space for the water passage channel as large as possible, improve the water passage rate, and the sum of the relative lengths of the two bottom plates is also less than the width of the top plate, so that the two bottom plates do not contact each other, forming a support effect at two different positions, thereby improving the stability of the support.

[0076] In some embodiments, the first side plate 32 is detachably connected to the top plate 31; and / or the first side plate 32 is detachably connected to the first bottom plate 34; and / or the second side plate 33 is detachably connected to the top plate 31; and / or the second side plate 33 is detachably connected to the second bottom plate 35. The present invention, through the above structure, allows for easy disassembly of the support structure, thereby effectively facilitating the removal of the first windbreak structure inside the water passage, facilitating subsequent repair or maintenance.

[0077] In order to solve the problem of replacing the windshield float during after-sales maintenance, the present invention designs at least one plate of the support component as a detachable structure, which can be combined with the adjacent plate to form an assembly. The two are fixed together with screws, and the windshield float can be removed by disassembling the movable plate.

[0078] The present invention also provides an evaporator assembly, which includes the evaporator support assembly described in any of the preceding claims, and further includes an evaporator 1 and a water receiving tray 2, wherein the evaporator 1, the support component 3 and the water receiving tray 2 are arranged in sequence from top to bottom.

[0079] like Figure 1 and Figure 2 As shown, the ultra-thin evaporator compressor unit of the present invention generally includes a return air inlet, compressor, water tray, evaporator, baffle plate, fan or fan assembly, air outlet and outer sheet metal parts in the airflow direction. The evaporator is arranged at an angle to obtain a larger heat exchange area in this ultra-thin unit structure.

[0080] Clearly, the evaporator divides the condensate tray into two parts: the return air side condensate tray and the outlet air side condensate tray. The air pressure on the return air side is higher than that on the outlet air side. Under normal circumstances, the condensate produced on the evaporator flows downwards due to gravity and is also tilted towards the outlet air side by the airflow between the fins. Therefore, the amount of condensate in the outlet air side condensate tray is generally more than that in the return air side condensate tray.

[0081] like Figure 3 As shown, the bottom of the evaporator has a water-passing groove sheet metal part (i.e., support component 3), which is fixedly connected to the left and right side plates of the evaporator, respectively. This is mainly used to increase the robustness and stability of the evaporator components during production and assembly. It should be noted that the water-passing groove can also be made of a sufficiently strong plastic part. The advantage is that it is not susceptible to corrosion during long-term use in condensate water, but the disadvantage is that it requires mold manufacturing of the plastic part. Sheet metal water-passing grooves can usually be machined using CNC technology. To solve the corrosion problem, an anti-corrosion coating can be applied, or it can be directly made of stainless steel.

[0082] like Figure 3 and 3aAs shown, the water trough is roughly U-shaped with its opening facing downwards. Several slots are cut into its front and back sides to allow condensate to flow freely from the bottom. Obviously, some return air can also pass through these slots, causing air leakage. The water trough bends in the same direction and at the same height around its perimeter. There is a second bend on the long side that can bend inwards (U-shape) or outwards (i.e., the first and second bottom plates). The slots are located on both sides of the long side and the side of the second bend.

[0083] The above three technical solutions (Examples 1-3) are used to solve the air leakage problem of the water passage trough in the above structure.

[0084] The aforementioned "water passage + windbreak float" is formed as a component and fixed to the bottom of the evaporator, and placed on the water receiving tray.

[0085] The present invention also provides an air conditioner that includes the aforementioned evaporator assembly.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
