Description

Technical Field

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

[0002] At present, as people's requirements for air conditioning increase, the heat exchange area of ​​the evaporator is an important factor in judging the heat exchange capacity of the air conditioner.

[0003] In order to increase the heat exchange area of ​​the evaporator, the common practice of existing air conditioners is to increase the installation angle of the evaporator, which can increase the evaporator area to a certain extent, thereby improving the heat exchange area; or use a V-shaped evaporator (bent or spliced ​​type) to form a bent structure, thereby increasing the heat exchange area. However, since this method still uses an integral evaporator, the increase in heat exchange area is limited, and it is difficult to achieve a significant increase in the heat exchange capacity of the air conditioner. Summary of the invention

[0004] The problem solved by the present invention is how to increase the heat exchange area of ​​the air conditioner, thereby increasing the heat exchange capacity of the air conditioner.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] On the one hand, the present invention provides an air conditioning heat exchange component, including a shell and a plurality of evaporators, the shell having an air outlet end surface, the air outlet end surface being provided with an air outlet, the plurality of evaporators being arranged in sequence on the inner side of the air outlet and connected to the shell, wherein each of the evaporators is installed at an angle relative to the air outlet end surface, two adjacent evaporators are arranged at intervals, and the projections of the plurality of evaporators on the air outlet end surface at least cover the air outlet.

[0007] The air conditioner heat exchange component provided by the embodiment of the present invention sequentially arranges multiple evaporators on the inner side of the air outlet and connects to the shell, wherein each evaporator is installed at an angle relative to the air outlet end face, two adjacent evaporators are arranged at intervals, and the projections of the multiple evaporators on the air outlet end face at least cover the air outlet. When the air is actually discharged, since the projections of the multiple evaporators cover the air outlet, the airflow needs to pass through the multiple evaporators for heat exchange before being discharged, thereby ensuring the heat exchange effect. At the same time, since each evaporator is installed at an angle, the number of evaporators on the inner side of the air outlet can be increased, and the heat exchange area of ​​each evaporator is its own normal area, so the inclined setting can increase the heat exchange area on the same projection area, thereby increasing the total heat exchange area. Compared with the prior art, the air conditioner heat exchange component provided by the present invention, compared with the conventional integral evaporator, the present invention adopts a split evaporator, and through the inclined setting of multiple evaporators, the total heat exchange area can be greatly increased, thereby improving the heat exchange efficiency and the heat exchange capacity of the air conditioner.

[0008] Furthermore, the plurality of evaporators are arranged side by side and in parallel, and the projections of two adjacent evaporators on the air outlet end surface at least partially overlap.

[0009] The air conditioning heat exchange component provided by the embodiment of the present invention arranges multiple evaporators side by side and in parallel, which can ensure that the multiple evaporators are evenly distributed. At the same time, the projections of two adjacent evaporators on the air outlet end surface at least partially overlap, which can further ensure that the projections of the multiple evaporators can completely cover the air outlet, thereby ensuring the air outlet heat exchange effect.

[0014] Furthermore, an included angle α between each of the evaporators and the air outlet end surface is between 30° and 60°.

[0015] The air conditioning heat exchange assembly provided in the embodiment of the present invention can limit its installation space by reasonably setting the inclination angle of the evaporator to avoid occupying too much space inside the shell, while ensuring that multiple evaporators can completely block the air outlet to ensure the air outlet heat exchange effect.

[0016] Furthermore, the width of the overlapping area of ​​the projections of two adjacent evaporators on the air outlet end surface is 1 / 3-1 / 5 of the width of the projections of the evaporators on the air outlet end surface.

[0017] The air conditioner heat exchange assembly provided by the embodiment of the present invention can achieve secondary heat exchange at the edge of the evaporator by reasonably setting the width of the overlapping area, thereby improving the heat exchange capacity at the edge and ensuring the uniformity of heat exchange of multiple evaporators. At the same time, it can ensure that multiple evaporators are distributed throughout the air outlet without excessive heat waste.

[0018] Furthermore, the shell includes a top cover plate, a volute fixing plate and side panels, the side panels are arranged at both ends of the top cover plate and are partially bent to form the air outlet end surface, the air outlet is arranged between the two side panels, the volute fixing plate is arranged on the top cover plate and corresponds to the air outlet end surface, and the multiple evaporators are connected to the top cover plate and are arranged between the volute fixing plate and the air outlet.

[0019] The air conditioner heat exchange assembly provided by the embodiment of the present invention arranges the evaporator between the volute fixing plate and the air outlet, so that multiple evaporators can be reasonably distributed in the shell to ensure the heat exchange effect. In addition, the evaporator is connected to the top cover plate, so that the evaporator can be fixedly installed, ensuring its fixing effect.

[0020] Furthermore, each of the evaporators has a first end and a second end relative to each other in the installation direction, the first end is arranged close to the air outlet, and the ratio of the distance L3 between the air outlet end face and the volute fixing plate to the distance L4 between the second end and the volute fixing plate is greater than or equal to 1.7.

[0021] The air conditioning heat exchange assembly provided in the embodiment of the present invention can reserve sufficient pipe space to facilitate pipe routing by reasonably limiting the positional relationship between the end of the evaporator and the volute fixing plate, while avoiding interference caused by being too close to the volute fixing plate.

[0022] Furthermore, each of the evaporators is provided with an evaporation pipeline, and the evaporation pipeline is arranged between the volute fixing plate and the evaporator.

[0023] The air conditioning heat exchange assembly provided by the embodiment of the present invention arranges the evaporation pipeline between the volute fixing plate and the evaporator, avoiding the conventional side assembly arrangement and increasing the air outlet area of ​​the air outlet.

[0024] Furthermore, the air-conditioning heat exchange component also includes mounting foam, which is embedded in the shell and provided with a plurality of positioning grooves, and the plurality of evaporators are assembled in the plurality of positioning grooves in a one-to-one correspondence.

DETAILED DESCRIPTION

[0036] As disclosed in the background technology, in the prior art, for the heat exchange of air outlet of air conditioners, especially ducted air conditioners, an integral evaporator is usually installed inside the air outlet to achieve heat exchange of air outlet through the evaporator. In addition, in order to increase the heat exchange area, the common practice of the existing air conditioners is to increase the installation angle of the evaporator, which can increase a certain evaporator area, thereby increasing the heat exchange area; or use a V-shaped evaporator (bent or spliced ​​type) to form a bent structure, thereby increasing the heat exchange area. However, this method still uses an integral evaporator, resulting in a limited increase in the heat exchange area, and it is difficult to achieve a significant increase in the heat exchange capacity of the air conditioner.

[0037] Furthermore, the duct air conditioner in the prior art, due to the use of an integral evaporator, has an evaporation pipeline that can only be arranged at the end of the evaporator. In this case, the edge position of the air outlet is undoubtedly occupied, resulting in a limited air outlet area, making it difficult to increase the air outlet area.

[0038] In order to solve the above problems, the present invention provides an air conditioning heat exchange component and an air conditioner. In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] First embodiment

[0040] See also Figure 1 and Figure 2 This embodiment provides an air conditioner heat exchange assembly 100, which can greatly increase the heat exchange area, thereby improving the heat exchange efficiency and heat exchange capacity of the air conditioner. At the same time, it can increase the air outlet area and improve the air outlet efficiency.

[0041] An air conditioning heat exchange component 100 provided in this embodiment includes a shell 110 and a plurality of evaporators 130, the shell 110 has an air outlet end surface 150, and an air outlet 151 is arranged on the air outlet end surface 150, and the plurality of evaporators 130 are sequentially arranged on the inner side of the air outlet 151 and connected to the shell 110, wherein each evaporator 130 is installed obliquely relative to the air outlet end surface 150, two adjacent evaporators 130 are arranged at intervals, and the projections of the plurality of evaporators 130 on the air outlet end surface 150 at least cover the air outlet 151.

[0042] It should be noted that the air conditioning heat exchange assembly 100 in this embodiment is suitable for an air conditioner, which may be a duct air conditioner, wherein a plurality of evaporators 130 are sequentially arranged on the inner side of the air outlet 151 and connected to the housing 110, wherein each evaporator 130 is installed obliquely relative to the air outlet end face 150, two adjacent evaporators 130 are arranged at intervals, and the projections of the plurality of evaporators 130 on the air outlet end face 150 at least cover the air outlet 151. Here, the evaporator 130 is installed obliquely, which means that the installation direction of the evaporator 130 is inclined relative to the air outlet end face 150. During actual air outlet, since the projections of multiple evaporators 130 cover the air outlet 151, the airflow needs to pass through multiple evaporators 130 for heat exchange before being discharged, thereby ensuring the heat exchange effect. At the same time, since each evaporator 130 is installed at an angle, the number of evaporators 130 accommodated on the inner side of the air outlet 151 can be increased, and the heat exchange area of ​​each evaporator 130 is its own normal area. Therefore, the inclined setting can increase the heat exchange area on the same projection area, and then increase the total heat exchange area, thereby improving the heat exchange efficiency and the heat exchange capacity of the air conditioner.

[0043] It is worth noting that the heat exchange area of ​​a conventional ducted air conditioner is determined by the heat exchange area of ​​the integral evaporator, which can be 0.21m 2 The air conditioner provided in this embodiment has a total heat exchange area of ​​0.47m2 under the same external dimensions. 2 Therefore, the heat exchange efficiency can be improved by 123%, achieving a significant increase in heat exchange area and heat exchange efficiency.

[0044] The actual distribution of the multiple evaporators 130 in this embodiment is described in detail below. In this embodiment, the multiple evaporators 130 are arranged side by side and in parallel, and the projections of two adjacent evaporators 130 on the air outlet end surface 150 at least partially overlap. Specifically, the multiple evaporators 130 are arranged side by side and in parallel, which can ensure that the multiple evaporators 130 are evenly distributed. At the same time, the projections of two adjacent evaporators 130 on the air outlet end surface 150 at least partially overlap, which can further ensure that the projections of the multiple evaporators 130 can completely cover the air outlet 151, thereby ensuring the air outlet heat exchange effect. Of course, the multiple evaporators 130 are not limited to the side-by-side parallel arrangement. In other preferred embodiments of the present invention, the multiple evaporators 130 can also be arranged in other arrangement shapes such as W-shaped or wavy, which are not specifically limited here.

[0045] It should be noted that the evaporator 130 in this embodiment has a single size much smaller than a conventional integral evaporator, and is in the shape of a rectangular block as a whole. There are pipelines inside the evaporator 130, and the installation direction of the evaporator 130 in this embodiment refers to the long side direction of the evaporator 130 when installed, that is, the long side direction of the evaporator 130, and the pipeline direction inside the evaporator 130 is the same as the installation direction. During heat exchange, the internal airflow can realize heat exchange with the evaporator 130, and its heat exchange principle is the same as that of a conventional integral evaporator, which will not be introduced in detail here.

[0046] In this embodiment, the distance L1 between two adjacent evaporators 130 is between 50 mm and 70 mm. Specifically, L1 satisfies: 50 mm ≤ L1 ≤ 70 mm. Preferably, in this embodiment, the distance between two adjacent evaporators 130 may be 50 mm. The distance L1 between two adjacent evaporators 130 here refers to the normal distance between the two evaporators 130, as shown in the figure. By reasonably setting the distance L1 between two adjacent evaporators 130, multiple evaporators 130 can be reasonably distributed, and while ensuring the heat exchange effect, the number of evaporators 130 can be reasonably set to avoid material waste and cost increase.

[0047] In this embodiment, the length L2 of each evaporator 130 along the installation direction is between 200 mm and 310 mm. Specifically, L2 satisfies: 200 mm ≤ L2 ≤ 310 mm. Preferably, in this embodiment, the length L2 of each evaporator 130 along the installation direction may be 200 mm. The length L2 of the evaporator 130 here refers to the length along the installation direction, that is, the length of the long side of the evaporator 130, as shown in the figure. By reasonably setting the length L2 of the evaporator 130, its installation space can be limited to avoid occupying too much space inside the shell 110, while ensuring the heat exchange effect.

[0048] In this embodiment, the angle α between each evaporator 130 and the air outlet end surface 150 is between 30° and 60°. Specifically, the angle α here satisfies: 30°≤α≤60°. Preferably, the angle α between the evaporator 130 and the air outlet end surface 150 here can be 60°. In this embodiment, by reasonably setting the inclination angle of the evaporator 130, its installation space can be limited to avoid occupying too much space inside the housing 110, while ensuring that multiple evaporators 130 can completely block the air outlet 151 to ensure the air outlet heat exchange effect.

[0049] It should be noted that the angle α between the evaporator 130 and the air outlet end surface 150 here refers to the angle between the installation direction of the evaporator 130 and the air outlet end surface 150 , and the angle can represent the installation inclination angle of the evaporator 130 .

[0050] In this embodiment, the width of the overlapping area of ​​the projections of two adjacent evaporators 130 on the air outlet end surface 150 is 1 / 3-1 / 5 of the width of the projection of the evaporator 130 on the air outlet end surface 150. Preferably, the width of the overlapping area of ​​the projections of two adjacent evaporators 130 on the air outlet end surface 150 is 1 / 4 of the width of the projection of the evaporator 130 on the air outlet end surface 150, that is, the width of the overlapping part is 1 / 4 of the overall width. By reasonably setting the width of the overlapping area, the edge of the evaporator 130 can be subjected to secondary heat exchange, the heat exchange capacity at the edge can be improved, and the heat exchange uniformity of the multiple evaporators 130 can be ensured. At the same time, it can ensure that the multiple evaporators 130 are distributed throughout the air outlet 151 without excessive heat waste.

[0051] It should be noted that the width of the overlapping portion here is 1 / 4 of the overall width, which means that when measured from the perspective of the air outlet 151 , the width of the overlapping portion is 1 / 4 of the size of a single evaporator 130 .

[0052] It is worth noting that in this embodiment, the length L2 of the evaporator 130 and the width L1 between two adjacent evaporators 130 can be adjusted according to the installation inclination angle α of the evaporator 130, and the length L2 is inversely proportional to the inclination angle α, and the width L1 is also inversely proportional to the inclination angle α. The specific relationship diagram can be referred to Figure 5 . For example, in other preferred embodiments of the present invention, when the length L2 of the evaporator 130 is adjusted to the upper limit of 310 mm, the inclination angle α of the evaporator 130 needs to be reduced to ensure the internal pipeline arrangement. At this time, the width L1 between two adjacent evaporators 130 can be adjusted according to the overlapping size and the length L2. For example, the inclination angle α can be adjusted to 30°, and the width L1 between two adjacent evaporators 130 can be adjusted to 70 mm. Of course, in this embodiment, examples are given for the upper and lower limits of the size of the evaporator 130. In other preferred embodiments, the size of the evaporator 130 can also be between the upper and lower limits. At this time, other size angles can also be adaptively adjusted, which will not be listed here one by one.

[0053] See also Figures 2 to 4The housing 110 includes a top cover plate 111, a volute fixing plate 113 and a side panel 115. The side panels 115 are arranged at both ends of the top cover plate 111 and are partially bent to form an air outlet end surface 150. The air outlet 151 is arranged between the two side panels 115. The volute fixing plate 113 is arranged on the top cover plate 111 and corresponds to the air outlet end surface 150. A plurality of evaporators 130 are connected to the top cover plate 111 and are arranged between the volute fixing plate 113 and the air outlet 151. Specifically, the top cover plate 111 and the side panels 115 are integrally formed, the volute fixing plate 113 is arranged in the inner area of ​​the top cover plate 111, the plurality of evaporators 130 can be connected to the top cover plate 111 to be fixed, and the plurality of evaporators 130 can be arranged between the volute fixing plate 113 and the air outlet 151, so that the plurality of evaporators 130 can be reasonably distributed in the housing 110 to ensure the heat exchange effect. Furthermore, by connecting the evaporator 130 to the top cover plate 111 , the evaporator 130 can be fixedly installed, thereby ensuring the fixing effect thereof.

[0054] In the present embodiment, each evaporator 130 has a first end and a second end relative to each other in the installation direction, the first end is arranged close to the air outlet 151, and the ratio of the distance L3 between the air outlet end face 150 and the volute fixing plate 113 to the distance L4 between the second end and the volute fixing plate 113 is greater than or equal to 1.7. Preferably, the ratio of the distance L3 between the air outlet end face 150 and the volute fixing plate 113 to the distance L4 between the second end and the volute fixing plate 113 can be 1.7. Specifically, the first end of the evaporator 130 is the outer end, and the second end is the inner end. By defining L3 and L4, the installation position of the evaporator 130 can be defined, and by reasonably defining the positional relationship between the end of the evaporator 130 and the volute fixing plate 113, sufficient pipeline space can be reserved to facilitate the pipe routing, and at the same time, it can avoid interference caused by being too close to the volute fixing plate 113.

[0055] In this embodiment, each evaporator 130 is provided with an evaporation pipeline 131, and the evaporation pipeline 131 is arranged between the volute fixing plate 113 and the evaporator 130. Specifically, sufficient space is reserved between the volute fixing plate 113 and the air outlet end surface 150, so that multiple evaporators 130 can be installed on the one hand, and sufficient pipeline space can be reserved on the inner side of the evaporator 130 by defining L3 and L4 on the other hand, so as to facilitate the placement of the evaporation pipeline 131. In addition, the evaporation pipeline 131 is arranged between the volute fixing plate 113 and the evaporator 130, avoiding the conventional side assembly setting of the pipeline, and can increase the air outlet area of ​​the air outlet 151.

[0056] It is worth noting that the conventional integral evaporator has a pipeline port on the side, so it is necessary to set up sufficient pipeline space at the edge of the air outlet 151 to place the evaporation pipeline, which in turn occupies the air outlet area, reducing the area of ​​the air outlet 151 and affecting the air outlet area. In this embodiment, the multiple split evaporators 130 are tilted, so that the pipeline port of the evaporator 130 can be set on the inside corresponding to the volute fixing plate 113, and then the evaporation pipeline 131 can be placed between the evaporator 130 and the volute fixing plate 113, so that the pipeline space is transferred, thereby increasing the size of the air outlet 151.

[0057] Furthermore, the air conditioning heat exchange assembly 100 also includes a mounting foam 170, which is embedded in the housing 110 and provided with a plurality of positioning grooves 171, and the plurality of evaporators 130 are assembled in the plurality of positioning grooves 171 one by one. Specifically, the mounting foam 170 is a plate-shaped foam member, which can be embedded in the housing 110 to achieve fixation, and specifically, the mounting foam 170 can be embedded between the side panels 115 on both sides, and the mounting foam 170 can be squeezed and fixed by the side panels 115 on both sides. By providing the mounting foam 170, and the mounting foam 170 is embedded in the housing 110, on the one hand, the sealing of the air inlet side can be ensured to prevent the airflow from flowing between the evaporator 130 and the housing 110, and on the other hand, by providing the positioning grooves 171, the evaporator 130 can be positioned during assembly to improve the assembly efficiency, and the evaporator 130 can be limited after the assembly is completed to prevent the evaporator 130 from shifting.

[0058] It should be noted that the positioning groove 171 in this embodiment can be a rectangular groove, and its shape is compatible with the shape of the evaporator 130, so that the evaporator 130 can be directly assembled in the positioning groove 171 to achieve pre-fixation, and the evaporator 130 is limited after assembly to prevent it from shifting. In addition, since the installation foam 170 is a foam material, it has better flexibility than sheet metal materials. Therefore, after adding the installation foam 170, there is no gap on the assembly surface of the evaporator 130, and no wind will flow out from the gap of the contact surface, thereby improving the sealing of the air outlet side.

[0059] Furthermore, the air conditioning heat exchange assembly 100 also includes a plurality of fixing frames 190, and the plurality of fixing frames 190 are buckled on the plurality of evaporators 130 in a one-to-one correspondence. A clearance through hole 175 is also provided on the mounting foam 170, and the fixing frames 190 pass through the clearance through hole 175 and are connected to the housing 110. Specifically, the fixing frame 190 is in a bent shape, one end of which is buckled on the evaporator 130, and the other end passes through the clearance through hole 175 and is connected to the top cover plate 111 by screws. In this embodiment, by providing the fixing frame 190, and the fixing frame 190 is buckled on the evaporator 130 in a corresponding manner, the evaporator 130 can be prevented from shaking, and the installation stability of the evaporator 130 can be improved. At the same time, by providing the clearance through hole 175, it can be ensured that the fixing frame 190 is directly installed on the housing 110, so as to achieve good support and fixation.

[0060] In this embodiment, the fixing frame 190 includes an integrally formed buckle portion 191, an extension portion 193 and a connection portion 195. The buckle portion 191 is U-shaped and buckled on the side of the evaporator 130 away from the top cover plate 111. One end of the extension portion 193 is connected to the buckle portion 191, and the other end extends toward the top cover plate 111 and extends to the clearance through hole 175. The connection portion 195 is connected to the end of the extension portion 193 away from the buckle portion 191 and is bent. Specifically, the connection portion 195 is accommodated in the clearance through hole 175 and fits on the top cover plate 111. A screw hole is also provided on the connection portion 195. The connection portion 195 is fixed to the top cover plate 111 by screws to achieve fixed installation of the fixing frame 190.

[0061] It should be noted that the height of the fixing frame 190 here needs to be adapted to the height of the evaporator 130 to ensure that the fixing frame 190 can be fixedly buckled on the evaporator 130 after tightening the screws. In actual assembly, the front end of the installation foam 170 can be placed against the air outlet end surface 150 to complete the assembly. The length of the installation foam 170 here is adapted to the width between the two side panels 115, so the assembly can be completed directly without special assembly requirements. After the installation foam 170 is installed, the positioning groove 171 thereon is exposed, and the multiple evaporators 130 are aligned with the positioning groove 171 one by one to complete the assembly. At this time, the positioning groove 171 can play a role in fixing the evaporator 130. Finally, the corresponding installation fixing frame 190, the buckling part 191 at the upper end of the fixing frame 190 clamps the evaporator 130, and the connecting part 195 at the lower end penetrates the clearance hole 175 and is fixed to the top cover plate 111 by screws to complete the assembly.

[0062] In summary, the present embodiment provides an air conditioning heat exchange assembly 100, in which a plurality of evaporators 130 are sequentially arranged on the inner side of the air outlet 151 and connected to the housing 110, wherein each evaporator 130 is installed obliquely relative to the air outlet end surface 150, two adjacent evaporators 130 are arranged at intervals, and the projections of the plurality of evaporators 130 on the air outlet end surface 150 at least cover the air outlet 151. When the air is actually discharged, since the projections of the plurality of evaporators 130 cover the air outlet 151, the airflow needs to be discharged after heat exchange through the plurality of evaporators 130, thereby ensuring the heat exchange effect. At the same time, since each evaporator 130 is installed obliquely, the number of evaporators 130 inside the air outlet 151 can be increased, and the heat exchange area of ​​each evaporator 130 is its own normal area, so the oblique arrangement can increase the heat exchange area on the same projection area, thereby increasing the total heat exchange area. Compared with the prior art, the air conditioning heat exchange component 100 provided by the present invention adopts a split evaporator 130 compared with the conventional integral evaporator 130. By tilting the multiple evaporators 130, the total heat exchange area can be greatly increased, thereby improving the heat exchange efficiency and the heat exchange capacity of the air conditioner.

[0063] Second embodiment
