The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] In the description of the present invention, "first feature" and "second feature" may include one or more such features.

[0040] In the description of the present invention, “multiple” means two or more, and “several” means one or more.

[0041] Please refer to the following Figures 1-11 A computer room air conditioner 100 according to an embodiment of the present invention is described.

[0042] like Figures 1-6 As shown, a computer room air conditioner 100 according to an embodiment of the present invention may include a casing 10 , a heat exchanger 20 , a fan assembly 30 and an electronic control assembly 40 .

[0043] The housing 10 can be placed outdoors or indoors and is formed with an air inlet 11 and an air outlet 12. The heat exchanger 20 is disposed in the housing 10 and is adjacent to the air inlet 11. The fan assembly 30 is disposed in the housing 10 and is adjacent to the air outlet 12.

[0044] Specifically, the fan assembly 30 drives outdoor air into the casing 10 from the air inlet 11, and the outdoor air exchanges heat with the heat exchanger 20 to form a heat exchange airflow, which is then driven by the fan assembly 30 to flow out of the casing 10 from the air outlet 12 and into the room.

[0045] In this way, the machine room air conditioner 100 can selectively control the outdoor air to enter the casing 10 through the air inlet 11, and the outdoor air can be heat-exchanged with the heat exchanger 20 to form a heat-exchanged air flow, which is then driven by the fan assembly 30 to flow out of the casing 10 through the air outlet 12, thereby providing indoor cooling.

[0046] The refrigerant flows in the heat exchanger 20 to heat-exchange with the outdoor air entering the casing 10, so that the temperature of the outdoor air entering the casing 10 is reduced, and the temperature of the heat-exchanged air flow is lower than the indoor ambient temperature, so that the heat-exchanged air flow can cool the indoor environment when entering the indoor environment.

[0047] The electric control assembly 40 is arranged in the casing 10, and the casing 10 can protect the electric control assembly 40 from outdoor dust and rain, thereby ensuring the safety of the electric control assembly 40.

[0048] Further, the heat exchanger 20 and the fan assembly 30 are signal-connected with the electric control assembly 40, so that the flow of the refrigerant in the heat exchanger 20 can be controlled, and the operating state and rotation speed of the fan assembly 30 can be controlled, so as to control the temperature and flow rate of the heat-exchanged air flow in the machine room air conditioner 100, thereby adjusting the temperature and wind speed of the cold air blown into the indoor environment, and further adjusting the cooling efficiency of the machine room air conditioner 100 in the machine room.

[0049] In the embodiment of the utility model, the machine room air conditioner 100 can be selectively arranged indoors or outdoors, and the operating state can be adjusted according to the indoor temperature and the outdoor temperature, thereby ensuring the temperature adjustment of the machine room air conditioner 100 in the machine room.

[0050] In combination with Figure 3-Figure 6 As shown in the figure, the machine room air conditioner 100 can further include an electric control maintenance cover plate 50. The casing 10 is provided with an electric control maintenance opening 13 on one side in the first direction, the electric control assembly 40 corresponds to the electric control maintenance opening 13 in the first direction, and the electric control maintenance cover plate 50 is detachably arranged in the electric control maintenance opening 13.

[0051] On the one hand, when the machine room air conditioner 100 is normally working, the electric control maintenance cover plate 50 can be arranged on the electric control maintenance opening 13 to seal the electric control maintenance opening 13, thereby protecting the internal electric control assembly 40 and preventing the electric control assembly 40 from being eroded by external rainwater, and ensuring the normal working of the electric control assembly 40.

[0052] On the other hand, the electric control access 13 can be used to open the electric control access 13 only to carry out the maintenance of the electric control assembly 40 in the machine case 10 when the electric control assembly 40 fails. The electric control assembly 40 in the machine case 10 is arranged to correspond to the electric control access 13 on the machine case 10 in the first direction, so that the electric control assembly 40 can be quickly found when the electric control access 13 is opened, so as to facilitate the maintenance and replacement of the electric control assembly 40.

[0053] Further, the electric control assembly 40 is slidable relative to the electric control access 13 in the first direction to selectively extend from the electric control access 13.

[0054] Specifically, the electric control assembly 40 can be arranged inside the machine case 10 close to the electric control access 13. When the electric control assembly 40 needs to be maintained, the electric control cover plate 50 can be removed first, and then the electric control assembly 40 can be pulled out of the electric control access 13, so that the electric control assembly 40 is at least partially located outside the machine case 10. In this way, the electric control assembly 40 can be in a maintenance state, and sufficient maintenance space can be provided to facilitate the maintenance of the electric control assembly 40.

[0055] Further, after the maintenance is completed, the electric control assembly 40 only needs to be pushed back into the machine case 10, and the electric control cover plate 50 is arranged on the electric control access 13.

[0056] Among them, the handle 46 can be arranged on the side of the electric control assembly 40 facing the electric control access 13. The operator can control the electric control assembly 40 by holding the handle 46, which facilitates pulling out or pushing in the electric control assembly 40.

[0057] In this way, the space inside and outside the machine case 10 can be fully utilized. Not only can the installation of the electric control assembly 40 in the machine case 10 be ensured, and the protection of the electric control assembly 40 can be ensured, but also the maintenance of the electric control assembly 40 can be facilitated without increasing the volume of the machine room air conditioner 100, thereby reducing the cost of the machine room air conditioner 100.

[0058] It can be understood that, in order to ensure the pull-out design of the electric control assembly 40, a gap will exist between the electric control assembly 40 and the machine case 10. The electric control cover plate 50 can cover the electric control access 13, that is, the gap between the electric control assembly 40 and the machine case 10 can be covered.

[0059] In this way, not only can the electric control assembly 40 be prevented from being eroded by rainwater, but also rainwater can be prevented from entering the machine case 10 through the gap between the electric control assembly 40 and the machine case 10, thereby effectively improving the waterproof performance of the machine room air conditioner 100 and ensuring the normal operation of the machine room air conditioner 100.

[0060] In combination with Figure 7 and Figure 8As shown, the computer room air conditioner 100 may further include: a limit member 41, a limit rail 14 extending in a first direction is provided on the top of the casing 10 corresponding to the electric control component 40, the limit member 41 passes through the limit rail 14 and is connected to the electric control component 40, and the limit member 41 can slide along the limit rail 14 to selectively cooperate with the two ends of the limit rail 14 in the first direction.

[0061] On the one hand, when the electric control component 40 is pulled out from the electric control inspection port 13 to put the electric control component 40 in the inspection state, the limiting member 41 can eventually cooperate with the limiting slide rail 14 at one end in the first direction close to the electric control inspection port 13 to prevent the electric control component 40 from being directly pulled out and detached from the computer room air conditioner 100, thereby avoiding failure of the electrical connection between the electric control component 40 and other components.

[0062] On the other hand, when the pulled-out electric control assembly 40 is pushed back into the housing 10, the stopper 41 can eventually engage with the end of the stop rail 14 in the first direction, which is farther away from the electric control access opening 13, thereby preventing the electric control assembly 40 from being pushed too far inward and damaging other components inside the housing 10. In other words, the electric control assembly 40 is ensured to be in the correct assembly position, ensuring the normal operation of the computer room air conditioner 100.

[0063] With such a configuration, the embodiment of the present invention can realize a retractable design of the electric control component 40 without increasing the volume of the computer room air conditioner 100, thereby facilitating the inspection and maintenance of the electric control component 40 and reducing maintenance costs.

[0064] Combine Figure 6 and Figure 9 As shown, a guide rail 15 is provided at the bottom of the housing 10 corresponding to the electric control component 40 . The guide rail 15 extends in a first direction and is connected to the electric control inspection port 13 . The bottom of the electric control component 40 is slidably fitted with the guide rail 15 .

[0065] Specifically, two guide plates 151 extending in the first direction may be provided at the bottom of the housing 10 . A guide track 15 may be defined between the two guide plates 151 . The guide track 15 extends in the first direction and communicates with the electric control inspection port 13 .

[0066] The guide rail 15 corresponds to the bottom of the electric control component 40. The bottom of the electric control component 40 can be set in the guide rail 15 and slide with the guide rail 15. This can limit the sliding direction of the electric control component 40 and prevent the electric control component 40 from sliding in a direction other than the first direction.

[0067] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the limiting member 41 is a limiting bolt, and a nut 42 is provided on the top of the electric control component 40. When the electric control component 40 is located inside the housing 10, the nut 42 is located at an end of the electric control component 40 that is further away from the electric control inspection port 13 in the first direction.

[0068] In this way, during assembly, the electronic control component 40 can be first set in the casing 10, the nut 42 can be located below the limiting slide rail 14 and correspond to the limiting slide rail 14, and then the limiting bolt is passed through the limiting slide rail 14 and threadedly connected to the nut 42, so that a detachable connection between the limiting bolt and the nut 42 can be achieved, and the limiting bolt can be limited and matched with the two ends of the limiting slide rail 14 in the first direction.

[0069] In this way, the structure of the computer room air conditioner 100 can be made simpler and more reliable, the setting of the limiting member 41 on the electronic control component 40 can be facilitated, and the selective limiting cooperation between the limiting member 41 and the limiting slide rail 14 can be more stable and reliable.

[0070] Combine Figure 4 and Figure 5 As shown, a water retaining rib 16 is provided on the circumferential outer side of the electric control inspection port 13 .

[0071] Specifically, the electric control inspection port 13 is opened on the side wall of the casing 10. External rainwater can enter the gap between the electric control inspection cover 50 and the electric control inspection cover 50 along the side wall of the casing 10, and then enter the electric control inspection port 13, corroding the electric control component 40 and other components of the computer room air conditioner 100.

[0072] By providing a water retaining rib 16 on the circumferential outer side of the electric control access opening 13, the water retaining rib 16 can also be located on the circumferential outer side of the electric control assembly 40. Even if some rainwater flows along the side wall of the casing 10 into the gap between the electric control access cover 50 and the electric control access cover 50, the water retaining rib 16 can block the rainwater and prevent it from entering the interior of the casing 10 through the electric control access opening 13, thereby improving the waterproof performance of the computer room air conditioner 100 and ensuring the normal operation of the electric control assembly 40 and even the computer room air conditioner 100.

[0073] Combine Figure 3 、 Figure 4 and Figure 11 As shown, the electric control maintenance cover 50 can mainly include a cover body 51 and a flange 52. The cover body 51 covers the electric control maintenance opening 13. The flange 52 is arranged on the circumferential edge of the cover body 51 and is bent relative to the cover body 51. The flange 52 is in contact with the casing 10 and abuts against the water retaining rib 16.

[0074] Specifically, by setting the flange 52 on the circumferential edge of the cover body 51 and bending the flange 52 relative to the cover body 51, the flange 52 and the casing 10 are set parallel to each other, thus forming the basic structure of the electric control maintenance cover 50.

[0075] During assembly, the electric control maintenance cover plate 50 only needs to be covered on the outer periphery of the water retaining rib 16 , and the flange 52 can abut and cooperate with the water retaining rib 16 , thereby quickly positioning the electric control maintenance cover plate 50 in the correct assembly position.

[0076] Moreover, the electrical control inspection cover 50 can be installed and set only by making the flange 52 and the casing 10 fit together and connecting the flange 52 and the casing 10, so that the cover body 51 covers the electrical control inspection port 13 and cooperates with the water retaining rib 16 to achieve the sealing effect of the electrical control inspection port 13.

[0077] Optionally, a first perforation can be set on the flange 52 and a second perforation can be set on the casing 10, so that the fastener passes through the first perforation and the second perforation and performs a fastening action, thereby realizing a detachable connection between the electric control inspection cover 50 and the casing 10, so that the electric control inspection cover 50 can be detachably covered on the electric control inspection port 13.

[0078] Combine Figure 3 and Figure 11 As shown, a sealing member 53 is provided on the side of the flange 52 facing the housing 10 .

[0079] Specifically, considering that after the flange 52 is connected to the housing 10 , a gap still exists between the flange 52 and the housing 10 , rainwater can enter through the gap, affecting the normal operation of the electronic control component 40 .

[0080] By providing a sealing member 53 on the side of the flange 52 facing the housing 10, when the electric control maintenance cover 50 is placed on the electric control maintenance opening 13 and the flange 52 is connected to the housing 10, the sealing member 53 can be located between the flange 52 and the housing 10. In this way, the sealing member 53 can seal the gap between the flange 52 and the housing 10, preventing rainwater from penetrating, improving the waterproof performance, and ensuring the normal operation of the electric control assembly 40.

[0081] Combine Figure 3-Figure 6 As shown, the electronic control assembly 40 may include a wiring harness 43. The wiring harness 43 is led out from the electronic control assembly 40 and can be used to electrically connect with other components of the air conditioning system, such as the outdoor unit and sensors, to achieve signal and data transmission, thereby ensuring intelligent control of the computer room air conditioner 100.

[0082] Combine Figure 3-Figure 5As shown, the lower side of the electric control maintenance cover 50 is open and formed with a wire passing opening 54. A first wire passing clamp 44 is provided on the side of the electric control component 40 adjacent to the electric control maintenance opening 13 in the first direction. The first wire passing clamp 44 is located at the bottom of the electric control component 40 and seals the wire passing opening 54. The bottom of the wiring harness 43 passes through the first wire passing clamp 44 and extends to the outside of the electric control maintenance cover 50.

[0083] Specifically, to avoid the extension of the wiring harness 43, the lower side of the electric control maintenance cover 50 can be opened, so that a wire passage 54 can be formed on the lower side of the electric control maintenance cover 50, and the wire harness 43 can extend from the wire passage 54 to the outside of the electric control maintenance cover 50. In addition, because the wire passage 54 is formed on the lower side of the electric control maintenance cover 50, rainwater from above will not pass through the wire passage 54 and splash onto the electric control component 40. This can optimize the structural design of the electric control maintenance cover 50, reduce the erosion of the electric control component 40 by external rainwater, and ensure the safety of the electric control component 40.

[0084] It is understandable that although rainwater from top to bottom will not splash onto the electronic control component 40 through the wire opening 54, some splashed rainwater can still splash onto the electronic control component 40 through the wire opening 54, thereby causing the electronic control component 40 to fail.

[0085] By setting a first wire clamp 44 on one side of the electric control component 40 adjacent to the electric control inspection port 13 in the first direction, and locating the first wire clamp 44 at the bottom of the electric control component 40, the first wire clamp 44 can not only allow the wire harness 43 to pass through and extend to the outside, but also seal the wire opening 54 and seal with the wire harness 43.

[0086] That is, under the premise of ensuring the normal extraction of the wire harness 43, the first wire clamp 44 can be used to seal the wire opening 54, thereby preventing rainwater from eroding the electronic control component 40 through the wire opening 54, thereby ensuring the waterproof performance of the computer room air conditioner 100 and ensuring the safety of the electronic control component 40 and even the computer room air conditioner 100.

[0087] Combine Figure 4 and Figure 6 As shown, a second wire clip 45 is provided on one side of the electric control assembly 40 adjacent to the electric control inspection port 13 in the first direction. The wire harness 43 passes through the second wire clip 45 and extends to the outside of the electric control assembly 40 .

[0088] Specifically, the wire harnesses 43 converge at the wire opening 54 and are led out through the first wire clamp 44. However, the wire harnesses 43 still need to be led out of the housing of the electronic control assembly 40. Furthermore, it is understood that the housing of the electronic control assembly 40 also needs to be provided with perforations. Although the wire harnesses 43 can be led out through the perforations on the housing, there will be a gap between the wire harnesses 43 and the perforations, which will reduce the sealing and waterproof performance of the electronic control assembly 40.

[0089] The wire harness 43 can pass through the second wire clamp 45, and extend to the outside of the electric control assembly 40, so that the wire harness 43 is led out from the inside of the electric control assembly 40. In this way, the second wire clamp 45 can not only ensure the normal leading-out of the wire harness 43, but also seal with the wire harness 43, thereby improving the sealing performance and waterproof performance of the electric control assembly 40.

[0090] The number of the second wire clamps 43 can be at least two, and the at least two second wire clamps 43 are arranged at intervals on the side of the electric control assembly 40 adjacent to the electric control access hole 13 in the first direction. The specific arrangement positions of the at least two second wire clamps 43 can be determined according to the connection positions of different wire harnesses 43 with the inside of the electric control assembly 40, so as to shorten the lengths of the wire harnesses 43 and avoid the disorder of the wire harnesses 43.

[0091] In some embodiments of the present application, the first wire clamp 44 and the second wire clamp 45 are both rubber wire clamps, and the rubber wire clamps seal with the wire harness 43.

[0092] Specifically, the rubber part has excellent elasticity and sealing performance, so that the first wire clamp 44 and the second wire clamp 45 are both rubber wire clamps, and openings can be arranged on the first wire clamp 44 and the second wire clamp 45.

[0093] During the assembly of the electric control assembly 40 or even the machine room air conditioner, the wire harnesses 43 of the electric control assembly 40 can first pass through the openings on the second wire clamp 45, the wire harnesses 43 are pressed and seal with the second wire clamp 45, then the wire harnesses 43 pass through the openings on the first wire clamp 44 downwards, the wire harnesses 43 are pressed and seal with the first wire clamp 44, so as to lead out the wire harnesses 43.

[0094] In this way, by optimizing the first wire clamp 44 and the second wire clamp 45, the waterproof performance is further improved, so as to ensure the safe operation of the electric control assembly 40.

[0095] As shown in Figures 1-6 According to the embodiment of the present application, the machine room air conditioner 100 can include a casing 10, a heat exchanger 20, a fan assembly 30 and an electric control assembly 40.

[0096] The casing 10 can be arranged in an outdoor or indoor environment, and the casing 10 is formed with an air inlet 11 and an air outlet 12. The heat exchanger 20 is arranged in the casing 10 and adjacent to the air inlet 11. The fan assembly 30 is arranged in the casing 10 and adjacent to the air outlet 12.

[0097] Specifically, the fan assembly 30 drives outdoor air into the casing 10 from the air inlet 11, and the outdoor air exchanges heat with the heat exchanger 20 to form a heat exchange airflow, which is then driven by the fan assembly 30 to flow out of the casing 10 from the air outlet 12 and into the room.

[0098] In this way, the computer room air conditioner 100 can selectively control outdoor air to enter the casing 10 through the air inlet 11, and the outdoor air can form a heat exchange airflow after heat exchange with the heat exchanger 20, and then be driven by the fan assembly 30 to flow out of the casing 10 from the air outlet 12, thereby cooling the room.

[0099] The refrigerant flows in the heat exchanger 20 so that the outdoor air entering the casing 10 exchanges heat with the refrigerant in the heat exchanger 20. This can reduce the temperature of the outdoor air entering the casing 10, so that the temperature of the heat exchange airflow is lower than the indoor ambient temperature. In this way, when the heat exchange airflow enters the room, it can cool the room.

[0100] The electric control assembly 40 is disposed in the housing 10 , and the housing 10 can protect the electric control assembly 40 and prevent outdoor dust and rain from contaminating the electric control assembly 40 , thereby ensuring the safety of the electric control assembly 40 .

[0101] Furthermore, the heat exchanger 20 and the fan assembly 30 are both connected to the electronic control assembly 40 by signal, so that the flow of refrigerant in the heat exchanger 20 can be controlled, and the operating state and rotation rate of the fan assembly 30 can be controlled to control the temperature and flow rate of the heat exchange airflow formed in the computer room air conditioner 100, thereby adjusting the temperature and wind speed of the cold air blown into the room, and further adjusting the cooling efficiency of the computer room air conditioner 100 in the computer room.

[0102] In the embodiment of the present invention, the computer room air conditioner 100 can be selectively installed indoors or outdoors, and adjusts the operating state according to the indoor temperature and the outdoor temperature to ensure that the computer room air conditioner 100 regulates the temperature of the computer room.

[0103] Combine Figure 3-Figure 6 As shown, the computer room air conditioner 100 may further include an electric control access cover 50. An electric control access opening 13 is provided on one side of the housing 10 in the first direction. The electric control assembly 40 corresponds to the electric control access opening 13 in the first direction. The electric control access cover 50 is detachably provided on the electric control access opening 13.

[0104] On the one hand, when the computer room air conditioner 100 is working normally, the electric control inspection cover 50 can be covered on the electric control inspection port 13 to achieve sealing of the electric control inspection port 13, thereby protecting the internal electric control component 40, preventing the electric control component 40 from being eroded by external rainwater, and ensuring the normal operation of the electric control component 40.

[0105] On the other hand, the electronic control access opening 13 can be used to access the electronic control assembly 40 within the housing 10 by simply opening the electronic control access opening 13 when a fault occurs in the electronic control assembly 40. The electronic control assembly 40 within the housing 10 is arranged to correspond to the electronic control access opening 13 on the housing 10 in the first direction. This allows the electronic control assembly 40 to be quickly found when the electronic control access opening 13 is opened, facilitating repair and replacement of the electronic control assembly 40.

[0106] Furthermore, the electric control assembly 40 is slidable in a first direction relative to the electric control inspection opening 13 so as to selectively extend from the electric control inspection opening 13 .

[0107] Specifically, the electronic control assembly 40 can be disposed inside the housing 10 near the electronic control inspection opening 13. When the electronic control assembly 40 needs to be inspected, the electronic control inspection cover 50 can be removed first, and then the electronic control assembly 40 can be pulled out of the electronic control inspection opening 13, so that the electronic control assembly 40 is at least partially located outside the housing 10. This allows the electronic control assembly 40 to be in an inspection state, providing ample maintenance space and facilitating inspection of the electronic control assembly 40.

[0108] Furthermore, after the maintenance is completed, it is only necessary to push the electronic control assembly 40 back into the housing 10 and then cover the electronic control maintenance cover 50 on the electronic control maintenance opening 13 .

[0109] A handle 46 may be provided on the side of the electric control assembly 40 facing the electric control inspection port 13 , and the operator may control the electric control assembly 40 by holding the handle 46 , so as to facilitate pulling out or pushing in the electric control assembly 40 .

[0110] It is understood that to ensure the retractable design of the electronic control assembly 40, a gap exists between the electronic control assembly 40 and the housing 10. The provision of the electronic control access cover 50 can cover the electronic control access opening 13, that is, it can cover the gap between the electronic control assembly 40 and the housing 10. This not only prevents rainwater from eroding the electronic control assembly 40, but also prevents rainwater from entering the interior of the housing 10 through the gap between the electronic control assembly 40 and the housing 10, thereby effectively improving the waterproof performance of the computer room air conditioner 100 and ensuring the normal operation of the computer room air conditioner 100.

[0111] In this way, the space inside and outside the casing 10 can be fully utilized, which not only ensures the installation of the electronic control component 40 in the casing 10 and the protection of the electronic control component 40, but also facilitates the maintenance of the electronic control component 40 without increasing the volume of the computer room air conditioner 100, thereby reducing the cost of the computer room air conditioner 100.

[0112] Furthermore, a limiting portion is provided on the top of the electric control component 40 , and the limiting portion selectively limits and cooperates with the housing 10 in the first direction.

[0113] On the one hand, when the electronic control component 40 is pulled out from the electronic control inspection port 13 to put the electronic control component 40 in the inspection state, the limit portion can eventually cooperate with the upper limit of the casing 10 in the first direction to prevent the electronic control component 40 from being directly pulled out and detached from the computer room air conditioner 100, thereby avoiding failure of the electrical connection between the electronic control component 40 and other components.

[0114] On the other hand, when the pulled-out electronic control assembly 40 is pushed back into the housing 10, the stopper will eventually engage with the housing 10 in the upper limit position in the first direction, thereby preventing the electronic control assembly 40 from being pushed too far inward and damaging other components inside the housing 10. In other words, the electronic control assembly 40 is ensured to be in the correct assembly position, ensuring the normal operation of the computer room air conditioner 100.

[0115] With such a configuration, the embodiment of the present invention can achieve a retractable design of the electric control component 40 without increasing the volume of the computer room air conditioner 100, thereby facilitating the inspection and maintenance of the electric control component 40 and reducing maintenance costs.
