Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and in particular to an air conditioner outdoor unit and a computer room air conditioner. Background Art

[0002] The placement of the air conditioner outdoor unit is greatly affected by external factors, and the fins of the outdoor unit in a dusty area are easily covered with dust.

[0003] When the outdoor unit is working, the fan rotates to suck the air outside the unit into the internal space of the unit, and then blows it out of the unit from the fan. When the air passes through the condenser, it takes away the heat. Therefore, dust and impurities in the air generally adhere to the outside of the condenser. Because the outdoor unit does not have a coarse filter like the indoor unit to filter impurities in the air, over time, the surface of the condenser components of the outdoor unit is covered with a thick layer of impurities and dust, which reduces the contact area between the condenser and the air, reduces the air intake, and greatly affects the heat dissipation efficiency and unit performance of the unit.

[0004] Especially for the outdoor unit of the computer room air conditioner, the heat dissipation effect of the outdoor unit condenser is even less ideal. The reason is that the outdoor unit of the unit air conditioner makes a lot of noise, so sound insulation equipment such as soundproof sheds or soundproof walls are often added to the outdoor unit. However, facilities such as soundproof sheds and soundproof walls will place the outdoor unit in a relatively closed space, which invisibly further affects the heat dissipation efficiency and performance of the unit.

At the same time, when cleaning, water is sprayed from the inside to the outside of the heat exchanger, and the spray direction of the heat exchanger is opposite to the direction of dust erosion of the heat exchanger, so that the dust can be separated from the fins of the heat exchanger as soon as possible, and the cleaning effect is better. And it can ensure that the dirt falls to the outside of the heat exchanger. At the same time, the cleaning water can take away part of the heat of the fins to accelerate the heat dissipation of the fins and enhance the refrigeration performance of the unit.

[0074] Background

[0075] The placement of the air conditioner outdoor unit is greatly affected by external factors, and the fins of the outdoor unit in a dusty area are easily covered with dust.

[0076] When the outdoor unit is working, the fan rotates to suck the air outside the unit into the internal space of the unit, and then blows it out of the unit from the fan. When the air passes through the condenser, it takes away the heat. Therefore, dust and impurities in the air generally adhere to the outside of the condenser. Because the outdoor unit does not have a coarse filter like the indoor unit to filter impurities in the air, over time, the surface of the condenser components of the outdoor unit is covered with a thick layer of impurities and dust, which reduces the contact area between the condenser and the air, reduces the air intake, and greatly affects the heat dissipation efficiency and unit performance of the unit.

[0077] Especially for the outdoor unit of the computer room air conditioner, the heat dissipation effect of the outdoor unit condenser is even less ideal. The reason is that the outdoor unit of the unit air conditioner is noisy, so soundproofing equipment such as soundproofing sheds or soundproofing walls are often added to the outdoor unit. However, facilities such as soundproofing sheds and soundproofing walls will place the outdoor unit in a relatively closed space, which will further affect the heat dissipation efficiency and performance of the unit.

[0078] Based on this, Figure 1-Figure 7 As shown, the first aspect of the embodiment of the present application provides an air conditioner outdoor unit, comprising:

[0079] The heat exchanger assembly 100 and the connecting plate assembly 200 are connected together and enclosed to form an air cavity with an opening;

[0080] The fan assembly 300 is arranged at the opening position of the air cavity. When the fan assembly 300 is controlled to operate, the airflow outside the air cavity can enter the air cavity after heat exchange through the heat exchanger assembly 100 and be discharged through the opening of the air cavity;

[0081] A spray unit 400, the spray unit 400 is arranged inside the air cavity;

[0082] The spray unit 400 has a spray head 401 facing one side of the heat exchanger assembly 100, so that the heat exchanger assembly 100 can be flushed from the inside to the outside through the spray head 401. Preferably, the spray direction of the spray head 401 is perpendicular to the inner heat exchange surface of the heat exchanger assembly.

[0083] In the embodiment of the present application, by adding a spray unit 400 inside the outdoor unit, the spray unit 400 can be used to rinse the surface of the heat exchanger assembly 100. Spraying cleaning water on the heat exchanger assembly 100 can reduce its surface temperature, which has the function of assisting heat dissipation and increasing refrigeration performance. At the same time, the cleaning water is sprayed from the inside to the outside of the heat exchanger assembly 100 during cleaning, and its spraying direction on the heat exchanger assembly 100 is opposite to the direction in which dust erodes the heat exchanger assembly 100, so that the dust can be separated from the fins of the heat exchanger assembly 100 as soon as possible during cleaning, and the cleaning effect is better. And it can ensure that the dirt falls to the outside of the heat exchanger assembly 100. At the same time, the cleaning water can take away part of the heat of the fins to accelerate the heat dissipation of the fins and enhance the refrigeration performance of the unit. At the same time, the spray unit 400 in the embodiment of the present application is arranged inside the unit, which does not affect the appearance size of the unit. When the outdoor units are installed side by side, the installation position will not be limited due to the additional spray unit 400.

[0084] Further, in some possible implementations, such as Figure 1-Figure 5 As shown, the spray unit 400 can be controlled to move inside the wind cavity to change the spray position of the spray head 401 on the heat exchanger assembly 100 .

[0085] In the embodiment of the present application, by controlling the movement of the spray head 401 inside the outdoor unit, different positions of the heat exchanger assembly 100 can be cleaned, thereby improving the cleaning effect.

[0086] Further, in some possible implementations, such as Figure 1-Figure 5 As shown, the spray unit 400 includes a plurality of spray heads 401 distributed along the height direction of the heat exchanger assembly;

[0087] The plurality of spray heads 401 can be controlled to move along the length direction of the heat exchanger assembly 100 .

[0088] In the embodiment of the present application, a plurality of spray heads 401 are arranged along the height direction of the heat exchanger assembly 100, and the plurality of spray heads 401 are controlled to move along the length direction of the heat exchanger assembly 100. Thus, when the heat exchanger assembly 100 is flushed, the surface of the heat exchanger assembly 100 can be flushed in all directions, thereby avoiding flushing dead corners and improving the flushing effect of the heat exchanger assembly 100.

[0089] Further, in some possible implementations, such as Figure 1 and Figure 4As shown, the spray unit 400 also includes:

[0090] A spray pipe 402, the spray pipe 402 extends along the height direction of the heat exchanger assembly 100, and a plurality of spray heads 401 distributed along the height direction of the heat exchanger assembly 100 are connected to the spray pipe 402;

[0091] The air conditioner outdoor unit further includes a driving module 500 disposed inside the air cavity, and the driving module 500 is used to drive the spray pipe 402 to move along the length direction of the heat exchanger assembly 100 to change the spray position of the spray head 401 on the heat exchanger assembly 100 .

[0092] That is, when the spray unit 400 in the embodiment of the present application is started, the driving module 500 can drive the multiple spray heads 401 to move along the length direction of the heat exchanger assembly 100, thereby achieving an all-round flushing effect on the heat exchanger assembly 100.

[0093] Further, in some possible implementations, such as Figure 4 and Figure 5 As shown, the driving module 500 includes:

[0094] Driving motor 501;

[0095] A screw rod 502, which is in driving connection with the driving motor 501 and extends along the length direction of the heat exchanger assembly 100;

[0096] The slider 503 is threadedly coupled with the screw rod 502;

[0097] One end of the nozzle 402 in the length direction is connected to the slider 503 so that when the slider 503 moves in the length direction of the heat exchanger assembly 100 relative to the screw rod 502, the nozzle 402 can be driven to move along the length direction of the heat exchanger assembly 100 to change the spraying position of the nozzle 402 on the heat exchanger assembly 100.

[0098] Of course, in some alternative embodiments, other forms of driving modules may be used to drive the spray unit 400 to move, but it is relatively preferred to use a screw rod or a slider to drive the spray unit 400 because it has higher stability and lower cost.

[0099] Further, in some possible implementations, such as Figure 1 and Figure 2 As shown, the heat exchanger assembly 100 includes a first heat exchange unit 101 and a second heat exchange unit 102 that are correspondingly and obliquely arranged, and a V-shaped space with openings at the bottom, the side and the top is defined between the first heat exchange unit 101 and the second heat exchange unit 102;

[0100] The connecting plate assembly 200 includes a bottom plate 201 and a side plate 202, and the bottom plate 201 and the side plate 202 are respectively connected to the bottom opening position and the side opening position of the V-shaped space, so as to define a V-shaped air cavity with an opening at the top through the bottom plate 201, the side plate 202, the first heat exchange unit 101 and the second heat exchange unit 102;

[0101] The fan assembly 300 is arranged at the top opening of the air cavity.

[0102] In the embodiment of the present application, the heat exchanger assembly 100 is arranged in a V-shape. On the one hand, the V-shaped heat exchanger assembly 100 can reduce the adhesion of dust on the outside of the heat exchanger assembly 100 while ensuring the air intake volume. On the other hand, when the spray unit 400 sprays the V-shaped heat exchanger assembly 100, the spray water can more easily carry the dust downward, thereby improving the cleaning effect.

[0103] It should be noted that the V-shape mentioned in the embodiments of the present application only needs to be roughly in the shape of a V.

[0104] Further, in some possible implementations, such as Figure 1 and Figure 4 As shown, the spray unit 400 is provided with two groups, wherein the spray head 401 of one group of the spray units 400 corresponds to the first heat exchange unit 101, and the spray head 402 of the other group of the spray units 400 corresponds to the second heat exchange unit;

[0105] The bottoms of the two groups of spray units 400 are connected together to form a V-shaped spray assembly adapted to the V-shaped air cavity.

[0106] In the embodiment of the present application, the two groups of spray units 400 are also arranged in a V shape. On the one hand, the V-shaped space inside the unit is fully utilized to facilitate the placement of the spray unit 400. On the other hand, the multiple spray heads 401 on the spray unit 400 can all maintain the same distance from the heat exchanger assembly, so that the spray unit 400 can achieve a better spraying effect when spraying different positions of the heat exchanger assembly 100 through the multiple spray heads 401.

[0107] Furthermore, in some possible implementations, a connecting pipe 500 is provided between the spray pipes 402 of the two spray units 400, and a water inlet end of the connecting pipe 500 is connected to a water inlet pipe 600 of a flexible structure;

[0108] The side plate 202 is provided with a pipe hole 2021, and the water inlet end of the water inlet pipe 600 is placed outside the wind cavity through the pipe hole 2021. The water inlet pipe 600 placed outside the wind cavity is connected to a water pump or a water source (not shown in the figure).

[0109] Further, in some possible implementations, such as Figure 1 and Figure 2 As shown, the fan assembly 300 includes a wind frame surrounded by a plurality of frames 301 and a fan 302 disposed at the wind outlet of the wind frame;

[0110] The wind frame has an air inlet and an air outlet. The air inlet of the wind frame is connected to the top opening of the wind cavity, and a fan 302 is arranged at the air outlet of the wind frame.

[0111] The bottom of the spray unit 400 is connected to a driving module 500, and the top is slidably connected to the wind frame through a sliding member 700. When the driving module 500 drives the spray unit to move, the sliding member 700 on the top of the spray unit 400 slides on the wind frame.

[0112] The air conditioner outdoor unit further includes a support base 800 and a column 900 , wherein the support base 800 serves as a bottom support member of the air conditioner outdoor unit, and the column 900 serves as a side support member of the air conditioner outdoor unit.

[0113] Specifically, the sliding member 700 is a pulley disposed on the top of the nozzle 402 and connected to the nozzle 402 through a connecting arm, and the pulley is slidably connected to the guide rail on the longitudinal beam of the wind frame. The V-shaped spray assembly can move in the left and right direction {i.e., the length direction of the heat exchanger assembly} along with the movement of the bottom slider 503; similarly, the top pulley rolls on the longitudinal beam along with the movement of the V-shaped nozzle.

[0114] Further, in some possible implementations, such as Figure 5-Figure 7 As shown, the shower head 401 includes:

[0115] A valve body 4011, wherein a first cavity 40111 and a second cavity 40112 are separated from each other, and a water inlet channel 40113 connecting the first cavity 40111 and the second cavity 40112 is formed inside the valve body 4011, and a water inlet 40114 connecting the first cavity is formed on the surface of the valve body 4011;

[0116] A valve core 4012, the valve core 4012 is connected to the valve body 4011, at least part of the valve core 4012 is located in the second cavity 40112 of the valve body 4011, a water outlet channel 40121 is formed inside the valve core 4012, and a plurality of honeycomb holes 40122 distributed along the length direction of the valve core 4012 are formed on the surface of the valve core 4012, and the plurality of honeycomb holes 40122 are all connected to the water outlet channel 40121;

[0117] The length of the valve core 4012 in the second cavity 40112 of the valve body 4011 can be adjusted so that water entering the second cavity 40112 from the water inlet channel 40113 can communicate with different numbers of honeycomb holes 40122 to change the water output of the water outlet channel 40121 on the valve core 4012.

[0118] Preferably, the spray unit 400 is provided with a plurality of spray heads 401 , and the water output of the plurality of spray heads 401 from top to bottom is designed such that the water output of the spray head 401 located at the bottom is greater than the water output of the spray head 401 located at the top.

[0119] The reason why the water output of multiple spray heads 401 in the embodiment of the present application is designed to be: the water output of the lower spray head 401 is greater than the water output of the upper spray head 401, because when the heat exchanger assembly 100 is cleaned, the dirt after cleaning flows downward along the fins of the heat exchanger assembly 100, and the more dirt there is downward, so the amount and intensity of water sprayed on the bottom of the condenser must be larger to clean the dirt accumulated at the bottom of the heat exchanger assembly 100.

[0120] Specifically, in some possible implementations, such as Figure 6 and Figure 7 As shown, the valve body 4011 is provided with a threaded hole inside;

[0121] The surface of the valve core 4012 is formed with an external thread section 4a adapted to the threaded hole. The valve core 4012 is connected to the valve body 4011 through the cooperation of the external thread section 4a and the threaded hole. In the length direction of the valve core 4012, the valve core 4012 also includes a valve core head section 4b and a valve core tail section 4c formed on both sides of the external thread section 4a. A plurality of honeycomb holes 40122 are formed on the surface of the valve core head section 4b.

[0122] When the valve core 4012 and the valve body 4011 are connected, at least part of the valve core head section 4b is located in the second cavity 40112, and by rotating the valve core 4012, the valve core head section 4b can move relative to the valve body 4011 to change the number of honeycomb holes 40122 in the valve core head section 4b that are connected to the valve body water outlet channel 4013.

[0123] In this way, when the water output of the sprinkler head 401 needs to be adjusted, the number of honeycomb holes 40122 in the valve core head section 4b connected to the valve body water outlet channel 4013 can be changed by rotating the valve core 4012 relative to the valve body 4011, thereby changing the water output of the sprinkler head 401.

[0124] Specifically, when the shower head 401 is assembled, the valve core of the shower head is adjusted to different tightness. The tightness of the valve core is from loose to tight from top to bottom {the definition in the embodiment of the present application is that the valve core is loose when it is screwed outward, and tight when it is screwed inward; the further the valve core is screwed inward, the more honeycomb water is connected to the water inlet channel of the valve body, and thus the more water output of the shower head 401}.

[0125] Further, in some possible implementations, such as Figure 6 and Figure 7As shown, a third cavity 40115 is further provided inside the valve body 4011, one end of the third cavity 40115 opens to the end of the valve body 4011, and the other end is connected to the threaded hole;

[0126] A sealing ring 4013 is sleeved on the outer periphery of the valve core tail section 4c, and the sealing ring 4013 is in sealing cooperation with the inner wall of the third chamber 40115.

[0127] In the embodiment of the present application, by providing a third chamber 40115 that connects the outside and the second chamber 40112, the valve core 4012 can be easily installed in the valve body 4011. At the same time, by providing a sealing ring 401 in the third chamber 40115, the cleaning water that has entered the second chamber 40112 can be prevented from flowing out through the third chamber 40115 while facilitating the installation of the valve core 4012.

[0128] Further, in some possible implementations, such as Figure 6 and Figure 7 As shown, a plurality of water inlet channels 40113 are provided between the first chamber 40111 and the second chamber 40112, and a plurality of channel water inlets of the plurality of water inlet channels 40113 are distributed in the length direction of the valve body 4011;

[0129] The shower head 401 further includes a piston 4014 disposed in the first chamber 40111, one end of the piston 4014 away from the water inlet 40114 of the valve body is connected to one end of an elastic member 4015, and the other end of the elastic member 4015 is connected to the end of the first chamber 40111 away from the water inlet 40114. The piston 4014 connected to the first chamber 40111 through the elastic member 4015 divides the first chamber 40111 into a first chamber A401111 and a second chamber B401112 with variable volumes, and the first chamber A401111 is connected to the water inlet 40114.

[0130] When the water inlet pressure of the water inlet 40114 is controlled to change, the piston 4014 can move in the first chamber 40111 to change the volume of the first chamber A401111 and the first chamber B401112, so that the water entering the first chamber A401111 can communicate with different numbers of water inlet channels 40113.

[0131] In the embodiment of the present application, a piston 4014 and an elastic member 4015 are arranged in the first chamber 40111, so that when the water inlet pressure of the water inlet 40114 is changed, the water entering the first chamber A401111 can be connected to different numbers of water inlet channels 40113 through the movement of the piston 4014 and the deformation of the elastic member 4015.

[0132] Specifically, Figure 6As shown, when the water pressure at the water inlet 40114 increases, the piston 4014 moves to the left and the elastic member 4015 is compressed. At this time, the volume of the first chamber A401111 increases, and the first chamber A401111 can communicate with more water inlet channels 40121, so that more water enters the second chamber 40112 and is discharged through the water outlet channel 40121 connected to the second chamber 40112, thereby increasing the water output of the sprinkler head 401.

[0133] Similarly, when the water inlet pressure of the water inlet 40114 decreases, the water output of the sprinkler head 401 will also decrease accordingly.

[0134] In summary, it can be seen that, in the embodiment of the present application, through the above-mentioned improvement of the spray head 401, the water spraying amount of the spray head 401 can be flexibly adjusted to improve the spraying effect on the heat exchanger assembly 100.

[0136] Furthermore, in some possible implementations, the air-conditioning outdoor units are provided in a plurality of groups, and the plurality of groups of air-conditioning outdoor units are spliced ​​together through their exterior surfaces.

[0137] It is worth noting that, since the spray unit 400 in the embodiment of the present application is arranged inside the outdoor unit, when multiple outdoor units are installed side by side, the installation position will not be restricted due to the additional spray units.
