[0030] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] The embodiment of the present application provides a heat exchanger installation structure to solve the technical problem in the prior art that condensed water generated at the end of the heat exchanger may drip outside the water receiving tray. The following will be described in conjunction with the accompanying drawings.

[0033] In the embodiments of the present application, Figure 1-Figure 4 As shown, the heat exchanger mounting structure includes at least one bracket 10, one end of the heat exchanger 40 is connected to the bracket 10 and encloses a water channel 20, and the water channel 20 is suitable for collecting condensed water generated at the end of the heat exchanger 40; a water receiving tray is arranged below the heat exchanger 40, and a guide structure 30 is arranged at one end of the bracket 10 close to the water receiving tray, and the guide structure 30 is used to drain the condensed water in the water channel 20 into the water receiving tray.

[0034] It should be noted that during the operation of the air conditioner, when the surface temperature of the evaporator is lower than the dew point temperature of the intake air flow, water vapor will condense on the surface of the evaporator to produce condensed water. Afterwards, most of the condensed water falls directly into the water receiving tray under the action of gravity. However, the condensed water produced on the curved pipe at the end of the evaporator may splash out of the water receiving tray during the dripping process, thereby causing a short circuit in internal components and causing safety problems.

[0035] To this end, the heat exchanger mounting structure provided in the present application connects one end of the heat exchanger 40 to the bracket 10, and one end of the heat exchanger 40 can be enclosed with the bracket 10 to form a water channel 20. The water channel 20 is used to collect condensed water generated at the end of the heat exchanger 40, and a guide structure 30 is set at one end of the bracket 10 close to the water receiving tray. The condensed water in the water channel 20 can be drained into the water receiving tray through the guide structure 30, which is beneficial to prevent the condensed water at the end of the heat exchanger 40 from splashing outside the water receiving tray during the dripping process, thereby ensuring the safety performance of the air conditioner. Compared with the prior art, the heat exchanger mounting structure provided in the present application not only has the function of supporting the heat exchanger 40, but also has the function of drainage. It integrates multiple functions into one, which is beneficial to simplify the internal structure of the air conditioner and improve user experience.

[0036] It can be understood that the heat exchanger 40 is usually tilted in the shell of the air conditioner, that is, the plane where the heat exchanger 40 is located is set at a certain angle with the horizontal plane, and the angle can be 30°, 45° or 60°. In this way, compared with the heat exchanger 40 set horizontally or vertically, the heat exchange area of ​​the heat exchanger 40 is increased, and the heat exchange effect is improved.

[0037] Since the heat exchanger 40 is fixed on the bracket 10, the inclination angle of the bracket 10 determines the inclination angle of the heat exchanger 40. In this embodiment, the bracket 10 can be installed obliquely on the inner wall of the air conditioner casing. Due to the inclined setting of the bracket 10, the condensed water in the water channel 20 can flow directly under the action of gravity, and then the condensed water flows into the water receiving tray after the diversion effect of the diversion structure 30.

[0038] In some embodiments, the heat exchanger 40 is an evaporator, and the evaporator may be a V-shaped evaporator. Accordingly, the bracket 10 is also a bracket 10 with a V-shaped structure.

[0039] Optionally, in one embodiment, see Figure 1-Figure 3 The bracket 10 includes a first mounting plate 11 and a second mounting plate 12 arranged on the first mounting plate 11; the heat exchanger 40 includes an end plate 41 and a curved pipe 42 arranged on the end plate 41, the end plate 41 is fixed on the first mounting plate 11, and the first mounting plate 11, the second mounting plate 12 and the end plate 41 enclose a water channel 20, and the curved pipe 42 is arranged in the water channel 20.

[0040] Specifically, the bracket 10 is an "L"-shaped structure, that is, the first mounting plate 11 and the second mounting plate 12 are both flat plates, the second mounting plate 12 is arranged at the edge of the first mounting plate 11, and the second mounting plate 12 is arranged perpendicular to the first mounting plate 11. Figure 2 A flange extending toward one side of the bracket 10 is provided at the periphery of the end plate 41, and the end plate 41 is screwed to the first mounting plate 11 through the flange. The second mounting plate 12 can be fixed to the inner wall of the air conditioner housing by screws, thereby enclosing a water channel 20 between the first mounting plate 11, the second mounting plate 12 and the end plate 41.

[0041] When the air conditioner is running, the condensed water generated on the bend pipe 42 first drips into the water channel 20, then flows in the water channel 20, and flows into the water receiving tray after the diversion effect of the diversion structure 30, thereby preventing the condensed water generated on the bend pipe 42 from splashing outside the water receiving tray during the dripping process.

[0042] Optionally, in one embodiment, see Figure 3 and Figure 4 The guide structure 30 includes a first guide plate 31 arranged on the first mounting plate 11, and a second guide plate 32 arranged on the second mounting plate 12. The first guide plate 31 and the second guide plate 32 are both inclined toward one side of the water receiving tray, and the first guide plate 31 and the second guide plate 32 are spaced apart to form a drain port 33 for drainage.

[0043] Specifically, one end of the first mounting plate 11 close to the water receiving tray is flush with one end of the second mounting plate 12 close to the water receiving tray, the first guide plate 31 and the second guide plate 32 are both flat, and the angle between the first guide plate 31 and the first mounting plate 11 is an obtuse angle, and the angle between the second guide plate 32 and the second mounting plate 12 is also an obtuse angle, so that the condensed water in the water channel 20 can flow along the first guide plate 31 and the second guide plate 32 under the action of gravity. In addition, in this embodiment, the first guide plate 31 and the second guide plate 32 can also be set to a roughly V-shaped structure, so that the condensed water in the water channel 20 can flow into the water receiving tray through the drain port 33 between the first guide plate 31 and the second guide plate 32.

[0044] Optionally, in one embodiment, see Figure 2 A positioning piece 111 is provided on the first mounting plate 11 , a positioning groove 411 is provided on the end plate 41 , and the positioning piece 111 is installed in the positioning groove 411 .

[0045] Specifically, the positioning groove 411 can be set through the flange of the end plate 41, the positioning piece 111 and the second mounting plate 12 are set on the same side of the first mounting plate 11, and the shape and size of the positioning piece 111 are adapted to the shape and size of the positioning groove 411, so that the positioning piece 111 can be inserted into the positioning groove 411. In this embodiment, the positioning piece 111 and the positioning groove 411 are arranged to facilitate the rapid positioning of the heat exchanger 40 and the bracket 10 when installing the heat exchanger 40, and facilitate the screws to pass through the screw holes on the end plate 41 and the first mounting plate 11 in sequence, thereby simplifying the installation of the heat exchanger 40, reducing the difficulty of installing the heat exchanger 40, and improving the installation efficiency of the heat exchanger 40.

[0046] Optionally, in one embodiment, see Figure 1 and Fig. 9 The heat exchanger mounting structure includes at least two brackets 10 , and the at least two brackets 10 include a first bracket 13 and a second bracket 14 that are spaced apart. One end of the heat exchanger 40 is connected to the first bracket 13 , and the other end of the heat exchanger 40 is connected to the second bracket 14 .

[0047] Specifically, the first bracket 13 and the second bracket 14 are both arranged in an "L" shape, and the first bracket 13 and the second bracket 14 are arranged opposite to each other. The heat exchanger 40 includes a first end and a second end. The first end and the second end of the heat exchanger 40 are both provided with an end plate 41, and each end plate 41 is provided with a bend pipe 42. The end plate 41 at the first end of the heat exchanger 40 is connected to the first mounting plate 11 of the first bracket 13. The first bracket 13 is suitable for receiving condensed water generated at the first end of the heat exchanger 40, and then the condensed water is discharged into the water receiving pan through the guide structure 30 on the first bracket 13; the end plate 41 at the second end of the heat exchanger 40 is connected to the first mounting plate 11 of the second bracket 14. The second bracket 14 is suitable for receiving condensed water generated at the second end of the heat exchanger 40, and then the condensed water is discharged into the water receiving pan through the guide structure 30 on the second bracket 14.

[0048] In this embodiment, a bracket 10 is provided at the first end and the second end of the heat exchanger 40, which not only makes the installation of the heat exchanger 40 more stable, but also can collect condensed water generated at both ends of the heat exchanger 40 through the two brackets 10, thereby further improving the safety performance of the air conditioner.

[0049] Optionally, in one embodiment, see Figure 5-Figure 7 ,as well as Fig. 9 A first mounting bracket 131 is provided at one end of the first bracket 13 close to the second bracket 14 , and a second mounting bracket 141 is provided at one end of the second bracket 14 close to the first bracket 13 . The first mounting bracket 131 and the second mounting bracket 141 are used to mount the electric heater 50 .

[0050] It is understandable that some air conditioners are equipped with an electric heater 50, such as energy storage air conditioners. The electric heater 50 is used when the set temperature in the shell of the energy storage air conditioner is higher than the actual temperature. In order to ensure that the energy storage battery operates within a suitable temperature and humidity range, the energy storage air conditioner starts to enter the heating mode. At this time, it is necessary to turn on the electric heater 50 to protect the battery in the container, prevent thermal runaway, low-temperature capacity attenuation and other problems, and improve the battery life.

[0051] Specifically, the first mounting frame 131 is connected to the first bracket 13 by screws, and the second mounting frame 141 is connected to the second bracket 14 by screws. One end of the electric heater 50 can be mounted on the first mounting frame 131 and fixed by screws to the first mounting frame 131, and the other end of the electric heater 50 can be mounted on the second mounting frame 141 and fixed by screws to the second mounting frame 141, thereby fixing the electric heater 50 between the first bracket 13 and the second bracket 14.

[0052] In this embodiment, the installation of the heat exchanger 40 and the electric heater 50 can be completed simultaneously through the heat exchanger installation structure, which simplifies the assembly process of fixing the heat exchanger 40 and the electric heater 50 in the air conditioner casing, not only making the structure inside the air conditioner more compact, but also improving the installation efficiency and reducing product costs.

[0053] The heat exchanger mounting structure provided in this embodiment has the functions of installing the heat exchanger 40, installing the electric heater 50, and discharging condensed water at the end of the heat exchanger 40. It can integrate multiple functions into one, which is beneficial to simplify the internal structure of the air conditioner and improve the user experience.

[0054] Optionally, in one embodiment, see Figure 5 , Figure 7 and Fig.10 The first mounting frame 131 and the second mounting frame 141 are both provided with folded edges 132 , and the folded edges 132 abut against the electric heater 50 to position the electric heater 50 .

[0055] Specifically, when installing the electric heater 50, the electric heater 50 can be positioned in the height direction by placing the bottom of the electric heater 50 on the folded edge 132, and then Fig. 9 By moving the electric heater 50 in the left and right directions, the screw holes on the first mounting bracket 131 and the second mounting bracket 141 can be aligned with the screw holes on the electric heater 50, so that the electric heater 50 is conveniently connected to the first mounting bracket 131 and the second mounting bracket 141 by screws, thereby simplifying the installation of the electric heater 50, reducing the installation difficulty of the electric heater 50, and improving the installation efficiency of the electric heater 50.

[0056] Optionally, in one embodiment, see Figure 7 , Figure 8 and Fig.10 The second bracket 14 is provided with a pipe opening 142 , and a shielding plate 143 is provided at the pipe opening 142 . When the pipeline of the heat exchanger 40 passes through the pipe opening 142 , the shielding plate 143 is connected to the second bracket 14 to shield the pipe opening 142 .

[0057] Specifically, the pipe opening 142 is used for the pipes of the heat exchanger 40 to pass through, and the pipe opening 142 is much larger than the outer diameter of the pipes of the heat exchanger 40, so that the pipes of the heat exchanger 40 will not be deformed when passing through the pipe opening 142, thereby ensuring the heat exchange performance of the heat exchanger 40. After the heat exchanger 40 is installed, the shielding plate 143 is screwed to the second bracket 14, so that the shielding plate 143 can be used to shield the pipe opening 142, thereby ensuring the overall sealing performance of the bracket 10.

[0058] Optionally, in one embodiment, the bracket 10 is an integrally formed structure. For example, the bracket 10 can be integrally injection molded. The bracket 10 made of plastic can prevent the bracket 10 from rusting due to long-term contact with condensed water, which is beneficial to reducing the maintenance cost of the air conditioner. At the same time, the integrally injection molded bracket 10 is beneficial to shortening the processing cycle and reducing the production cost of the product.

[0059] The present application also provides an air conditioner. Fig.11 The air conditioner includes a housing and a heat exchanger mounting structure. The specific structure of the heat exchanger mounting structure refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the bracket 10 is installed on the housing.

[0060] Specifically, the shell includes a first side plate and a second side plate that are arranged opposite to each other, and the bracket 10 includes a first bracket 13 and a second bracket 14. When assembling the heat exchanger 40 and the electric heater 50, the first bracket 13 is first fixed to the first side plate, and the second bracket 14 is fixed to the second side plate. Then, one end of the heat exchanger 40 is connected to the first bracket 13, and the other end is connected to the second bracket 14, so that the installation of the heat exchanger 40 is completed. Then, one end of the electric heater 50 is connected to the first mounting bracket 131, and the other end is connected to the second mounting bracket 141, so that the installation of the electric heater 50 is completed. The installation of the heat exchanger 40 and the electric heater 50 can be completed at the same time through the heat exchanger mounting structure, which simplifies the assembly process of fixing the heat exchanger 40 and the electric heater 50 in the air conditioner shell, which not only makes the structure inside the air conditioner more compact, but also improves the installation efficiency and reduces the product cost.
