The heat exchanger assembly 100 includes at least two heat exchange portions 110, at least two heat exchange portions 110 are connected in turn along the width direction, and the two adjacent heat exchange portions 110 are arranged at an included angle, for example, the heat exchanger assembly 100 may include two heat exchange portions 110 arranged at an included angle to each other to form a two-fold heat exchanger; or the heat exchanger assembly 100 comprises three heat exchange portions 110 connected in sequence, wherein every two adjacent heat exchange portions 110 are arranged at an included angle to form a tri-fold heat exchanger and the like. For the heat exchanger assembly 100 in the wall-mounted air conditioner indoor unit, when the heat exchanger assembly 100 comprises two heat exchangers, two heat exchange portions 110 are arranged to form a flaring through an included angle, the front side and the rear side of the heat exchanger assembly 100 are connected to the shell of the air conditioner indoor unit in a sealing mode, the shell is provided with an air inlet connected with the flaring and an air outlet communicated with the air inlet, and the air inlet, the flaring and the air outlet form an air outlet channel. Of course, in other embodiments, the two heat exchange portions 110 may be located on the front side and the middle side respectively, and the rear side of the inner cavity of the housing is provided with another heat exchange portion 110 or a wind deflector connected with the heat exchange portion 110 on the middle side at an included angle, where the wind deflector and the sealing plate 140 together achieve the effect of sealing the gap between the heat exchanger assembly 100 and the air duct.
The heat exchanging part 110 in the heat exchanger assembly 100 has two ends in a length direction in order to facilitate the integral installation thereof, wherein one end of the heat exchanging part 110 is fixedly installed with the supporting member 120, and the other end is installed with the connection plate 130 in order to facilitate the connection of the line or the pipe, on the one hand, the integral installation of the heat exchanger assembly 100 to the housing through the supporting member 120 and the connection plate 130 is facilitated; on the other hand, when the heat exchanging part 110 is mounted to the housing through the supporting member 120 and the connection plate 130, the supporting member 120 and the connection plate 130 also function to seal the openings at opposite ends of the heat exchanging part 110 such that the opening direction of the heat exchanging part 110 is directed only toward the air duct.
The sealing plate 140 of the heat exchanger assembly 100 is used to seal a gap between at least two heat exchanging portions 110 disposed at an angle. One end of the sealing plate 140 is connected with the supporting member 120, and the other end is connected with the connecting plate 130, so that the connection procedure between the sealing plate 140 and the heat exchange part 110 is simplified, and the assembly efficiency is improved; in addition, the two ends of the sealing plate 140 along the length direction are respectively connected with the supporting member 120 and the connecting plate 130 to realize the connection between the sealing plate 140 and the heat exchange portion 110, so that the damage degree to the heat exchange portion 110 can be reduced, and the heat exchange portion 110 is ensured to have better heat exchange efficiency. Specifically, the connection between the sealing plate 140 and the supporting member 120, and the connection between the sealing plate 140 and the connecting plate 130 may be by screw connection, snap connection, or plugging.
According to the technical scheme, one end of the sealing plate 140 is connected with the supporting piece 120, the other end of the sealing plate 140 is connected with the connecting plate 130, and the sealing plate 140 seals a gap between two adjacent heat exchange parts 110, so that a worker can realize the effect of connecting the sealing plate 140 with the heat exchange parts 110 by only connecting the sealing plate 140 with two ends of the heat exchange parts 110.
As shown in fig. 2, in order to ensure that the connection between the sealing plate 140 and the connecting plate 130 is firm, the sealing plate 140 and the connecting plate 130 are fixedly connected by screws.
Specifically, referring to fig. 2, 6 and 8 in combination, the connecting plate 130 is provided with a mounting lug 131 protruding towards a direction away from the supporting member 120, and the mounting lug 131 is provided with a first mounting hole 1311; one end of the sealing plate 140 is provided with a connecting lug 143, and the connecting lug 143 is provided with a second mounting hole 1434; screws are inserted through the first and second mounting holes 1311 and 1434 to fixedly connect the connection plate 130 with the sealing plate 140.
Through the arrangement, screw connection between the sealing plate 140 and the connecting plate 130 can be ensured, and the sealing plate 140 can be prevented from being separated from the connecting plate 130 when falling, so that the sealing plate 140 is prevented from being separated from the heat exchange part 110, and a good sealing effect of the sealing plate 140 on the adjacent two-fold heat exchange part 110 is ensured. In addition, the mounting lugs 131 are provided with the mounting lugs 131 protruding toward the direction away from the supporting member 120, so that after the condensed water is accumulated on the sealing plate 140, the condensed water is prevented from flowing into the flaring formed by the heat exchanging part 110 after flowing to the end of the sealing plate 140 connected with the connecting plate 130.
Of course, in other embodiments, in order to achieve the effect of fixedly connecting the sealing plate 140 and the connecting plate 130 through the screw, based on the premise that the sealing plate 140 can seal the heat exchange portion 110, one of the sealing plate 140 and the connecting plate 130 may further be convexly provided with a screw post, and the other one is provided with a screw hole, and the screw penetrates through the screw hole and the screw post to achieve the effect of fixedly connecting the sealing plate 140 and the connecting plate 130.
Further, as shown in fig. 2 or 6, the connection lug 143 includes a mounting portion 1431 overlapping the mounting lug 131 and a reinforcing portion 1432 disposed at an angle with the mounting portion 1431, the mounting portion 1431 has a second mounting hole 1434, and a barb portion 1433 is formed at an end of the reinforcing portion 1432 away from the mounting portion 1431.
Through reinforcing part 1432 and installation department 1431 being the contained angle setting, on the one hand can guarantee the intensity of the installation department 1431 of seting up second mounting hole 1434, on the other hand can make the reinforcing part 1432 of engaging lug 143 and the terminal of installing lug 131 on the connecting plate 130 of the bending part that installation department 1431 of engaging lug 143 is connected to the realization is predestined the effect that is located installing lug 131 with the engaging lug 143. By forming the barb portion 1433 at the end of the reinforcement portion 1432 remote from the mounting portion 1431, the barb portion 1433 has an effect of reinforcing the strength of the end of the reinforcement portion 1432 remote from the mounting portion 1431.
Further, as shown in fig. 6, the reinforcing portion 1432 extends downward, and the barb portion 1433 is bent in a direction away from the heat exchanging portion 110.
It will be appreciated that, in the air conditioning indoor unit, the water receiving groove provided at the lower end of the heat exchanger unit 100 can have an effect of draining condensed water into the water receiving groove by extending the reinforcing portion 1432 downward. In addition, the barb portion 1433 is bent in a direction away from the heat exchange portion 110, so that condensed water on the barb portion 1433 can be prevented from being sucked into the air duct. Of course, it is understood that the reinforcement 1432 may extend vertically downward or obliquely downward in a direction away from the heat exchange portion 110 to avoid condensate water from being introduced into the flared mouth (where the flared mouth is understood to be a portion of the air duct) of the plurality of heat exchange portions 110 semi-enclosed by the reinforcement 1432.
Further, the distance from the end surface of the heat exchange part 110 far from the support 120 to the support 120 is D1, and the distance from the end surface of the sealing plate 140 far from the support 120 to the support 120 is defined as D2, wherein D2-D1 is more than or equal to 5mm.
Through the above arrangement, the distance from the end surface of the heat exchange part 110 far away from the supporting member 120 to the supporting member 120 is smaller than the distance from the end surface of the sealing plate 140 far away from the supporting surface to the supporting member 120, so that condensed water gathered on the sealing plate 140 can be prevented from flowing into an air duct formed by the heat exchange part 110 and the air conditioner indoor unit shell through the end of the sealing plate 140, which is mounted with the connecting plate 130. Based on this scheme, if D2-D1 is less than 5mm, the condensed water on the sealing plate 140 is easily affected by the wind wheel 300 in the air duct of the air conditioner indoor unit and blown into the air duct, so that the phenomenon that the condensed water is blown out from the air outlet of the air conditioner indoor unit is easy to occur.
In order to achieve the connection of the sealing plate 140 to the support 120, the sealing plate 140 is plugged into the support 120. The sealing plate 140 and the supporting member 120 are connected in a plugging manner, so that the installation efficiency of the sealing plate 140 and the supporting member 120 is improved.
Specifically, referring to fig. 4, 5 and 7 in combination, one of the supporting member 120 and the sealing plate 140 is provided with a fastening hole 121, and the other is provided with a fastening buckle 144, and the fastening buckle 144 is inserted into the fastening hole 121. For example, the supporting member 120 is provided with a fastening hole 121, and the end of the sealing plate 140 near the supporting member 120 is provided with a fastening button 144, and the fastening button 144 is inserted into the fastening hole 121; alternatively, on the premise that the sealing plate 140 seals the gap of the heat exchanging part 110, the sealing plate 140 is provided with a fastening hole 121, and the supporting member 120 is convexly provided with a fastening 144, and the fastening 144 is inserted into the fastening hole 121. Further, the extending direction of the insert 144 may be set to be identical to the length direction of the plate body of the sealing plate 140, so that the sealing plate 140 may be prevented from being easily detached from the supporting member 120 after the insert 144 is fastened into the fastening hole 121. In addition, in order to facilitate insertion of the buckle 144 into the buckle hole 121, the end of the buckle 144 may have a chamfer so that the end of the buckle 144 forms a tapered structure to facilitate insertion of the buckle 144 into the buckle hole 121.
Referring to fig. 5 and fig. 7 in combination, it can be understood that, based on the scheme of fixedly connecting the sealing member to the connection plate 130, if the heat exchanger assembly 100 is light, the sealing member and the supporting member 120 can be simply connected in a plugging manner, so that the connection step between the sealing member and the heat exchange portion 110 can be simplified. If the heat exchanger assembly 100 is heavy, in order to improve the stable connection effect between the sealing member and the heat exchange portion 110, the buckle 144 may further have a first connecting hole 1441, the support member 120 has a second connecting hole 122, and the screw passes through the first connecting hole 1441 and the second connecting hole 122 to fixedly connect the support member 120 with the sealing member.
By providing the first connecting hole 1441 in the insert buckle 144, the sealing member and the supporting member 120 can be connected by a screw. By this arrangement, the same seal can simultaneously be connected to a lighter multi-fold heat exchanger or to a heavier multi-fold heat exchanger. It will be appreciated that when the seal is connected to a lighter weight multi-fold heat exchanger, one end of the seal is simply inserted into the support 120, thereby simplifying the connection process.
Further, as shown in fig. 5, when the first connecting hole 1441 is formed on the basis of the insert buckle 144, the end of the insert buckle 144 is bent towards the direction deviating from the inside of the included angle formed by the two adjacent heat exchange portions 110 to form a flange 1442, and the extending direction of the flange 1422 is parallel to the extending direction of the insert buckle 144. By doing so, the strength of the tab 144 around the first connecting hole 1441 can be improved. The flanging 1442 is bent towards the inner direction of the included angle formed by deviating from the two adjacent heat exchange portions 110, so that after the eye-splice 144 is prevented from being inserted into the buckling hole 121, a gap is formed between at least part of the area of the eye-splice 144 and the supporting member 120, and further, condensed water is prevented from flowing into the heat exchange portions 110, even into the air channel, through the gap between the eye-splice 144 and the supporting member 120.
In addition, the extending direction of the inserting buckle 144 may be parallel to the length direction of the heat exchange portion 110, and the sealing plate 140 is inserted into the buckling hole 121 along the length direction, so that the sealing plate 140 may be limited in the thickness direction thereof, and further the sealing plate 140 is prevented from being detached from the heat exchange portion 110 in the thickness direction thereof, so as to ensure that the sealing plate 140 has a good sealing effect on the gap between two adjacent heat exchange portions 110.
In order to improve the installation strength of the sealing plate 140, as shown in fig. 5 or fig. 6, in the technical solution of the present invention, the sealing plate 140 includes two sealing wings 141 disposed at an included angle and a connecting section 142 connecting the two sealing wings 141, two adjacent heat exchange portions 110 have two opposite sealing end surfaces 111, and the two sealing wings 141 are disposed in parallel and in a sealing manner with the sealing end surfaces 111 adjacent thereto.
The sealing plate 140 comprises two sealing wings 141 arranged at an included angle and a connecting section 142 for connecting the two sealing wings 141, so that when the sealing wings 141 are parallel to the two oppositely arranged sealing end faces 111 and are arranged in a sealing manner, the sealing wings 141 are attached to the sealing end faces 111 in the air inlet direction, and a better sealing effect is achieved. Further, since the sealing fin 141 is disposed in parallel with the sealing end face 111 adjacent thereto, the bending strength of the sealing fin 141 in the air intake direction is large. The sealing plate 140 with the above structure has a better bending strength scheme, and the thickness of the sealing plate 140 with the above structure can be reduced, for example, the thickness of the sealing plate 140 in the technical scheme of the invention can be not more than 0.6mm, so that the production cost of the sealing plate 140 is reduced.
Further, the connecting section 142 forms at least one water sump 1421. At least one water collecting groove 1421 is formed by the connecting section 142 between the sealing wings 141, so that condensed water on the sealing plate 140 can be collected in the water collecting groove 1421, and then when the condensed water is accumulated to a certain amount, the condensed water can flow to two ends of the water collecting groove 1421 and then to a water receiving disc of the indoor unit of the air conditioner, thereby avoiding the condensed water from entering an air flue formed by the heat exchange part 110 and the shell. Specifically, the cross-sectional shape of the sealing plate 140 may be V-shaped or W-shaped, etc.
It will be appreciated that the end of the sealing wing 141 (i.e. the end of the sealing wing 141 remote from the connecting section 142) is relatively weak, and in this embodiment, the end of one sealing wing 141 is folded back towards the other sealing wing 141 to form a folded portion 1411. By this arrangement, the strength of the end of the sealing fin 141 can be further enhanced, and the bending resistance of the sealing fin 141 as a whole can be improved.
Referring to fig. 9 and 10 in combination, in order to ensure a better heat exchange effect, the copper tube 112 of the heat exchange portion 110 has a first projection on the sealing end surface 111, the sealing wing 141 has a second projection on the sealing end surface 111, and a overlapping area of the first projection and the second projection is smaller than a projection area of a single copper tube 112 in the heat exchange portion 110 on the sealing end surface 111.
The copper tube 112 of the heat exchange portion 110 is used for heat exchange, and the fewer the portion of the copper tube 112 is shielded, the more the heat exchange efficiency of the heat exchange portion 110 can be improved. By the arrangement, the sealing wings 141 can not be completely blocked to the copper pipe 112, so that a good heat exchange effect of the non-blocked copper pipe 112 is realized.
For the purpose of proceeding, heat insulating members 150 are interposed between the sealing wings 141 on both sides of the sealing plate 140 and the adjacent heat exchanging part 110.
By sandwiching the heat insulating member 150 between the sealing wing 141 and the heat exchanging part 110, the temperature at two sides of the sealing plate 140 has a larger difference, so that the temperature at one side of the heat exchanging part 110 is higher, and the temperature at the other side is lower, on one hand, the temperature of the air blown out from the air outlet of the indoor unit of the air conditioner can be ensured to be relatively close to the temperature of the air at one side of the heat exchanging part 110, which faces the air outlet, thereby having good heat exchanging effect, and on the other hand, the heat exchanging efficiency can be improved. Specifically, the heat insulating member 150 may be heat insulating cotton or heat insulating foam, etc., which not only has a heat insulating effect, but also plays a buffering role between the sealing plate 140 and the heat exchanging part 110.
