Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a heat exchange component and an air conditioner. Background Art

[0002] During the operation of the refrigeration terminal, when the humid air passes through the heat exchanger, the moisture in it turns into condensed water on the low-temperature fins or copper tube surfaces. After long-term refrigeration operation, the moisture will form frost on the evaporator, affecting the heat exchange efficiency. Therefore, when the system runs the defrost program, a large amount of water will be generated. If the defrost water cannot be effectively collected and discharged, it will inevitably affect the user experience and safety issues in special environments. Traditional air conditioner indoor units are equipped with a water collection pan at the bottom of the evaporator. Under the action of gravity, water droplets naturally drip onto the drip pan and flow out through the external pipe. This solution has good water collection and drainage effects in a stable environment. However, in an unstable environment or when a large amount of water is generated by defrosting, the water collection pan has poor drainage effect and may even be unable to collect water. Therefore, a water collection structure suitable for unstable environments such as aircraft or ships is needed.

[0003] The applicant of this invention previously applied for patent CN113803874A, which utilizes a deflector plate 5 and a water collection trough 6 at the bottom of the deflector plate to prevent water dripping and achieve water collection. However, during actual aircraft or ship operation, the evaporator often tilts more than 60 degrees. In such cases, the water collection trough 6 of the patented invention cannot effectively collect water, and splashing of water droplets still occurs, resulting in poor water collection.

[0004] Due to the technical problems such as unstable vibrations in other special air conditioners such as aircraft-mounted, ship-mounted or vehicle-mounted air conditioners in the prior art, the evaporator cannot catch water in the water receiving tray, especially when it is tilted at a large angle, causing condensed water to splash or flow outside the water receiving tray, affecting the performance of the air conditioner. Therefore, the present invention studies and designs a heat exchange component and an air conditioner. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art of other special air conditioners such as airborne, shipborne or vehicle-mounted air conditioners that the evaporator cannot catch water due to unstable vibration, especially when it is tilted at a large angle, causing condensed water to splash or flow to places outside the water tray, affecting the performance of the air conditioner, thereby providing a heat exchange component and an air conditioner.

[0006] In order to solve the above problems, the present invention provides a heat exchange component, which includes:

[0008] In some embodiments, the first bending portion is located below the second bending portion, and the first bending portion is located at the bottom end of the main body.

[0009] In some embodiments, the first water storage tank further comprises a first drainage structure, wherein a first drainage hole is provided at the bottom end of the first bent portion, and the first drainage hole is connected to the first drainage structure, so that the water stored in the first water storage tank is drained through the first drainage hole and the first drainage structure;

[0010] It also includes a second drainage structure. The bottom end of the second bent portion is provided with a second drainage hole. The second drainage hole is connected to the second drainage structure to drain the water stored in the second water storage tank through the second drainage hole and the second drainage structure.

[0011] In some embodiments, the first drainage structure is a water receiving tray structure or a drainage pipe structure, the second drainage structure is a drainage pipe structure, and the first drainage structure is located below the second drainage structure; the second drainage structure has a drainage outlet;

[0012] The drain outlet is opposite to the first water storage tank so that water discharged from the drain outlet can enter the first water storage tank; or when the first drainage structure is a water receiving tray structure, the drain outlet is opposite to the first drainage structure so that water discharged from the drain outlet can enter the first drainage structure.

[0013] In some embodiments, a water pump, a first drain pipe and a second drain pipe are further included, wherein one end of the first drain pipe is connected to the first drainage structure and the other end is connected to the water pump, and one end of the second drain pipe is connected to the water pump and the other end can discharge condensed water.

[0014] In some embodiments, there are multiple water receiving structures, and in a vertical cross-sectional plane, the multiple water receiving structures are arranged in sequence and spaced apart along the length direction of the heat exchanger.

[0015] In some embodiments, in a vertical cross section, the first water storage tank is an elliptical arc groove or a circular arc groove, and / or the second water storage tank is an elliptical arc groove or a circular arc groove.

[0016] In some embodiments, when the first water storage tank and the second water storage tank are both elliptical arc tanks, the structures and dimensions of the first water storage tank and the second water storage tank are the same, and the short axis length of the elliptical arc tank is b; the main body is a straight plate structure, and the distance between the upper ends of the main bodies of two adjacent water receiving structures is l2; in the vertical section, the heat exchanger is a rectangular structure, and its two long sides are respectively located at the upper and lower ends, and the two short sides are respectively located on the sides in the horizontal direction, and the inclination angle between the extension direction of the main body and the short side is β, the length of the main body is l1, and the inclination angle of its bottom side to the horizontal direction when the heat exchanger is tilted is α, and the above parameters satisfy the following relationship: l2<l1·sinβ+2bcosβ.

[0017] In some embodiments, in a vertical cross-section plane, with the midline of the long side of the heat exchanger as the dividing line, at least one water receiving structure located on one side of the dividing line constitutes a first blocking unit, and at least one water receiving structure located on the other side of the dividing line constitutes a second blocking unit, the upper end of the main body of the water receiving structure in the first blocking unit is connected to a position below the heat exchanger or connected to the lower end of the heat exchanger, and the lower end extends obliquely in a direction away from the dividing line; the upper end of the main body of the water receiving structure in the second blocking unit is connected to a position below the heat exchanger or connected to the lower end of the heat exchanger, and the lower end extends obliquely in a direction away from the dividing line, forming a structure in which two blocking units extend obliquely in opposite directions.

[0018] In some embodiments, a shell is further included, and the heat exchanger and the water receiving structure are both arranged in the shell. The lower end of the shell is formed as an air inlet end, and the upper end is formed as an air outlet end. The multiple water receiving structures divide the air inlet channel, so that subdivided channels for air intake are formed between the water receiving structure and the shell, and between two adjacent water receiving structures. The airflow after passing through the subdivided channels enters the heat exchanger for heat exchange.

[0019] In some embodiments, an air duct is provided at the lower end of the air inlet end of the shell, and the air flow in the air duct can enter the interior of the shell through the air inlet end; a fan is also provided on the upper end of the shell located at the heat exchanger.

The first bent portion is located on the first side surface of the main body and is bent upward, and the second bent portion is located on the second side surface of the main body and is bent upward. Water storage tank structures (i.e., the first water storage tank and the second water storage tank) that are bent upward can be effectively formed on both sides of the main body. Therefore, when the heat exchanger is tilted at a large angle, water can be effectively collected by the water storage tank structures on both sides, thereby reducing or even preventing condensed water in the heat exchanger from directly falling into the air duct below. This can effectively solve the problem in the prior art of other special air conditioners such as airborne, shipborne, or vehicle-mounted air conditioners that the evaporator cannot collect water due to unstable vibration, especially when it is tilted at a large angle, causing condensed water to splash or flow outside the water receiving pan, thereby affecting the performance of the air conditioner. Water can still be collected when the evaporator is tilted at a large angle, thereby improving the water collection effect.

[0024] 2. The present invention also defines multiple dimensional relationships among the distance between two adjacent water receiving structures, the length of the main body, the size of the water storage tank, and the tilt angle of the main body. This allows the heat exchanger to effectively and completely receive water even when tilted at a large angle, provided that the following relationship, l2 < l1·sinβ + 2bcosβ, is satisfied. Furthermore, the evaporator can effectively receive water even when the tilt angle α is within a range of 0° to 90°, thereby improving the present invention's ability to receive water and prevent condensed water from splashing into the air duct.

[0025] 3. The present invention arranges drainage pipes at the bottom of both water storage tanks, so that when the evaporator is tilted at a large angle in all directions, water can be effectively discharged, further improving the present invention's ability to collect water and prevent condensed water from splashing into the air duct; the present invention also forms independent air inlet channels between two adjacent water baffles and the shell, which has a diversion function and can greatly alleviate the problem of uneven heat exchange of the evaporator; the present invention also uses a water absorption device attached to the water baffle to effectively buffer and absorb larger droplets when they fall, thereby solving the problem of condensed water splashing.

[0033] like Figure 1-5 As shown, the present invention provides a heat exchange component, which includes:

[0034] The heat exchanger 2 and the water receiving structure 3, the water receiving structure 3 is located below the heat exchanger 2, and the water receiving structure 3 includes a main body 31, a first bent portion 32 and a second bent portion 33. The main body 31 is a baffle structure, one end of the main body 31 is connected to the position below the heat exchanger 2 or connected to the lower end of the heat exchanger 2, and the other end extends downward. One end of the first bent portion 32 is connected to the first side surface of the main body 31, and the other end is bent upward to form a first water storage tank 34. One end of the second bent portion 33 is connected to the second side surface of the main body 31, and the other end is bent upward to form a second water storage tank 35. The first side surface and the second side surface are two opposite side surfaces.

[0035] The present invention provides a water receiving structure below the heat exchanger (preferably the evaporator), and the water receiving structure includes a main body, a first bent portion and a second bent portion. The first bent portion is located on the first side surface of the main body and bends upward, and the second bent portion is located on the second side surface of the main body and bends upward, which can effectively form a water storage tank structure (i.e., the first water storage tank and the second water storage tank) that bends upward on both sides of the main body, so that when the heat exchanger is tilted at a large angle, water can be effectively collected by the water storage tank structures on both sides, reducing or even preventing the condensed water in the heat exchanger from directly falling downward into the air duct below, thereby effectively solving the problem in the prior art that other special air conditioners such as airborne, shipborne or vehicle-mounted air conditioners cannot collect water due to unstable vibration, especially when the evaporator is tilted at a large angle, causing the condensed water to splash or flow outside the water receiving pan, thereby affecting the performance of the air conditioner. Water can still be collected when the evaporator is tilted at a large angle, thereby improving the water collection effect.

[0036] The improvements of the present invention are as follows:

[0037] 1. The water baffle of the present invention has curved sides and an elliptical water storage tank design at the front and back. It is evenly stacked in the air duct and can effectively catch dripping water droplets whether the evaporator unit is placed flat or tilted at a large angle.

[0038] 2. The water baffles in the air duct are evenly stacked, and independent air inlet channels are formed between the two adjacent water baffles and the shell. Under the effect of water blocking and diversion, the air flow field of the heat exchanger is evenly distributed, thereby improving the heat exchange efficiency of the heat exchanger.

[0039] 3. A thin sponge pad is added to the water retaining plate, which can effectively reduce the kinetic energy of the water droplets when they drip from top to bottom and prevent the water droplets from splashing.

[0040] 4. Arrange pipes at the bottom of the water retaining tank and the water storage tank, and install a micro water pump. When the evaporator tilts at a large angle in any direction, the water can be discharged effectively and quickly.

[0041] Beneficial effects:

[0042] The water receiving structure of the present invention is composed of eight side water baffles (water receiving structure) and one middle water baffle (water receiving structure). The bending angle of the water baffles, the size of the elliptical arc of the water storage tank, and the distance between the two side water baffles are proportional to each other. While having a good water blocking effect, it also functions as a guide plate, effectively increasing the uniformity of the flow field distribution of the airflow in the downwind duct and improving the heat exchange efficiency of the evaporator. The special design of the water baffles enables them to effectively block water generated by condensation or defrosting when the cooling unit is in an unstable environment (for example, when tilted at a large angle). A layer of sponge attached to the water receiving baffle of the present invention can effectively absorb the kinetic energy of falling water droplets and effectively absorb water droplets when they break. Compared with a design without a sponge, the present invention can effectively reduce water droplet splashing. In addition, the water storage tank adopts a quasi-elliptical design, and its opening direction is closely adjacent to the baffle. When water flows into the water storage tank, even if the cooling unit is in an unstable environment, the condensed water cannot splash out of the water storage tank until the stored water is discharged from the drain pipe, thereby achieving a good water storage effect.

[0043] In some embodiments, the first bend 32 is located below the second bend 33, and the first bend 32 is located at the bottom end of the main body 31. This is the preferred positional relationship between the first bend and the second bend of the present invention, that is, the first bend is located below the second bend, forming bends arranged vertically and on both sides, forming a water storage and water collection function with a vertical drop on both sides. In particular, by arranging the first bend at the bottom end of the main body, the water collection effect can be further improved, and condensed water can be further prevented from splashing into the air duct, so that as much water as possible is collected (through the two water storage tanks).

[0044] Figure 3 This is a schematic diagram of the defrosting water collection of the heat exchanger (i.e., evaporator) of the present invention. Condensed water is formed on the evaporator or melted water is formed by defrosting. In the process of dripping downward, even in an unstable environment at a large angle, due to the blocking effect of the water baffle (water collection structure 3), it will be collected in the elliptical arc-shaped water storage tank and quickly pumped into the main drainage pipe by a micro centrifugal pump to ensure that the dripping or defrosting condensed water will not splash out.

[0045] In some embodiments, a first drainage structure 8 is further included. A first drainage hole 81 is provided at the bottom end of the first bent portion 32. The first drainage hole 81 is connected to the first drainage structure 8 so that the water stored in the first water storage tank 34 can be drained through the first drainage hole 81 and the first drainage structure 8.

[0046] It also includes a second drainage structure 5 , and a second drainage hole 51 is provided at the bottom end of the second bending portion 33 . The second drainage hole 51 is connected to the second drainage structure 5 to drain the water stored in the second water storage tank 35 through the second drainage hole 51 and the second drainage structure 5 .

[0047] The present invention can discharge the water in the first water tank through the first drainage structure, preferably draining the water into the first drainage structure by means of the first drainage hole provided at the bottom end of the first bent portion, and can also discharge the water in the second water tank through the second drainage structure, preferably draining the water into the second drainage structure by means of the second drainage hole provided at the bottom end of the second bent portion. By discharging the condensed water in the two water tanks respectively through the two drainage structures, the function of the water tanks to continue storing water can be further ensured, and the effect of preventing the condensed water from falling into the air duct and preventing the condensed water from splashing can be improved.

[0048] In some embodiments, the first drainage structure 8 is a water receiving tray structure or a drainage pipe structure, the second drainage structure 5 is a drainage pipe structure, and the first drainage structure 8 is located below the second drainage structure 5; the second drainage structure 5 has a discharge port 52;

[0049] The discharge port 52 is opposite to the first water storage tank 34, so that the water discharged from the discharge port 52 can enter the first water storage tank 34; or when the first drainage structure 8 is a water receiving tray structure (at this time the water receiving tray does not completely cover the bottom of the evaporator, and will not completely block the intake air flow below, so that the air flow can pass through the water receiving tray from bottom to top and enter the evaporator for heat exchange), the discharge port 52 is opposite to the first drainage structure 8, so that the water discharged from the discharge port 52 can enter the first drainage structure 8.

[0050] This is the preferred structural form of the first drainage structure and the second drainage structure of the present invention. Both can be drainage pipes, or the upper drainage structure is a drainage pipe and the lower drainage pipe is a water receiving tray. Through the structural form of the drainage pipe, a closed space for the flow of condensed water can be formed, thereby further preventing the condensed water from flowing into the air duct or preventing the condensed water from splashing; and the second drainage structure can direct the water in the upper water tank into the lower water tank through the drainage port relative to the first water tank, and then discharge it through the drainage structure connected to the lower water tank; or when the lower drainage structure is a water receiving tray, the discharge port of the upper drainage pipe can also be directly opposite to the water receiving tray, so as to effectively drain the condensed water into the water receiving tray, completing the function of transferring and draining the water in the upper water tank.

[0051] In some embodiments, the device further includes a water pump 9 (preferably a micro-centrifugal pump), a first drain pipe 12, and a second drain pipe 13. One end of the first drain pipe 12 is connected to the first drainage structure 8 and the other end is connected to the water pump 9. One end of the second drain pipe 13 is connected to the water pump 9 and the other end is capable of draining condensed water. The present invention also utilizes the first drain pipe, the second drain pipe, and the water pump to pump and promptly drain water from the first drainage structure. Regardless of the direction of tilt, the micro-centrifugal pump can quickly, effectively, and promptly drain the water, further improving the effect of preventing condensed water from splashing and ensuring the effectiveness of the water collection device.

[0052] In some embodiments, there are multiple water receiving structures 3. In a vertical cross-sectional plane, the multiple water receiving structures 3 are sequentially spaced apart along the length of the heat exchanger 2. This is a further preferred structural form of the water receiving structure of the present invention. By having multiple water receiving structures spaced apart along the length of the heat exchanger, effective water receiving can be achieved along the length of the heat exchanger, further improving the water receiving effect and preventing condensed water from falling into the air duct or splashing.

[0053] In some embodiments, in a vertical cross-section, the first water storage tank 34 is an elliptical arc groove or a circular arc groove, and / or the second water storage tank 35 is an elliptical arc groove or a circular arc groove. This is a further preferred structural form of the first water storage tank and the second water storage tank of the present invention. The elliptical arc groove or the circular arc groove can form an upwardly concave structure, which can not only receive water from above but also prevent water from splashing, effectively increasing the water storage capacity and thus improving the water collection effect. The further preferred elliptical arc-shaped water storage tank can effectively prevent water from overflowing.

[0054] In some embodiments, when the first water storage tank 34 and the second water storage tank 35 are both elliptical arc grooves, the structures and dimensions of the first water storage tank 34 and the second water storage tank 35 are the same, and the short axis length of the elliptical arc groove is b; the main body 31 is a straight plate structure, and the distance between the upper ends of the main bodies 31 of two adjacent water receiving structures 3 is l2; in the vertical section, the heat exchanger 2 is a rectangular structure, and its two long sides are located at the upper and lower ends respectively, and the two short sides are located on the side in the horizontal direction, and the inclination angle between the extension direction of the main body 31 and the short side is β, the length of the main body 31 is l1, and the inclination angle of its bottom side to the horizontal direction when the heat exchanger 2 is tilted is α, and the above parameters satisfy the following relationship: l2<l1·sinβ+2bcosβ. The present invention also limits multiple dimensional relationships of the spacing between two adjacent water receiving structures, the length of the main body, the size of the water storage tank, and the inclination angle of the main body, so that a connection is formed between the upper end spacing l2 of the two adjacent water receiving structures and the length l1 of the main body, the inclination angle β, and the short axis length b. The spacing l2 is smaller than the sum of the length of the main body in the direction parallel to l2 and the length of the first and second water storage tanks in the direction parallel to l2, so that the gap can be effectively blocked by the main body, the first water storage tank, and the second water storage tank, forming an effective water receiving effect to prevent water from spilling at a large inclination angle; that is, when the following relationship l2<l1·sinβ+2bcosβ is satisfied, the heat exchanger can effectively receive water when it is tilted at a large angle (α is within 0~90°), thereby improving the water receiving and condensation water prevention capabilities of the present invention in splashing into the air duct.

[0055] In some embodiments, in a vertical cross-section, with the midline of the long side of the heat exchanger 2 as the dividing line 21, at least one water receiving structure 3 located on one side of the dividing line 21 constitutes a first blocking unit, and at least one water receiving structure 3 located on the other side of the dividing line 21 constitutes a second blocking unit. The upper end of the main body of the water receiving structure in the first blocking unit is connected to a position below the heat exchanger 2 or connected to the lower end of the heat exchanger 2, and the lower end extends obliquely in a direction away from the dividing line 21; the upper end of the main body of the water receiving structure in the second blocking unit is connected to a position below the heat exchanger or connected to the lower end of the heat exchanger, and the lower end extends obliquely in a direction away from the dividing line, forming a structure in which the two blocking units extend obliquely in opposite directions. By providing water receiving structures extending in opposite directions on both sides of the dividing line of the heat exchanger, the present invention can guide water falling from the heat exchanger from the middle to the edge, further effectively preventing condensed water from falling from the middle into the air duct below or splashing.

[0056] In some embodiments, a housing 10 is further included, wherein the heat exchanger 2 and the water receiving structure 3 are both disposed within the housing 10. The lower end of the housing 10 forms an air inlet end, and the upper end forms an air outlet end. The multiple water receiving structures 3 divide the air inlet channel, so that subdivided channels 14 for air intake are formed between the water receiving structure 3 and the housing 10, and between two adjacent water receiving structures 3. The airflow passing through the subdivided channels 14 enters the heat exchanger 2 for heat exchange. The present invention also subdivides the air inlet duct (preferably uniformly) through the coordination of the housing and the multiple water receiving structures, thereby improving the uniform heat exchange effect of multiple areas of the heat exchanger and improving the heat exchange efficiency.

[0057] The present invention preferably forms an independent and sealed channel with the housing 10 by evenly distributing the water receiving structure 3, so that the air flow to the evaporator is more evenly distributed, which can effectively improve the heat exchange efficiency of the evaporator.

[0058] In some embodiments, an air duct 4 is provided below the air inlet of the housing 10, allowing airflow in the duct 4 to enter the interior of the housing 10 through the air inlet. A fan 1 is also provided above the heat exchanger 2 on the housing 10. The present invention provides incoming airflow through the air duct below, while the fan above provides the power to drive the airflow.

[0059] In some embodiments, a water-absorbing device 11 is provided on the surface that contacts water of at least one of the main portion 31, the first bent portion 32, and the second bent portion 33. The water-absorbing device can be made of a sponge, a water-absorbing resin, wood fiber, quicklime, etc., with sponge being preferred. The present invention also utilizes a water-absorbing device attached to the water retaining plate to effectively buffer and absorb larger droplets, thereby resolving the issue of condensation water splashing.

[0060] Figure 4 This is a schematic diagram of the water baffle (i.e., water receiving structure). The condensed water formed on the evaporator or the melted water formed by defrosting has a large kinetic energy in the process of dripping downward. When it hits the water baffle, if there is no better buffering device, the water droplets will break into many small splashing water droplets and fly out of the lower air duct. Installing a thin sponge on the water baffle can effectively absorb the kinetic energy of the water droplets, prevent the water droplets from splashing, and also effectively absorb the dripping water droplets.

[0061] The present invention also provides an air conditioner, which includes the heat exchange component described in any of the preceding items.

[0062] 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 shall be included within the scope of protection of the present invention. The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
