The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 to 3, the present disclosure provides a cooling unit 100, and the cooling unit 100 may be applied to a data center. The cooling unit 100 is suitable for indoor installation, and can dissipate heat for heat generating devices such as servers and condensers. The cooling unit 100 includes a casing 10, a heat exchanger 30, and a blower 50, and both the heat exchanger 30 and the blower 50 may be mounted to the casing 10.
The outer contour of the case 10 may be substantially rectangular parallelepiped. The box body 10 is provided with an indoor air inlet channel 11, an indoor air supply channel 13, an outdoor air inlet channel 15, an outdoor air outlet 17 and a heat exchange space 19, the heat exchange space 19 is respectively communicated with the indoor air inlet channel 11, the indoor air supply channel 13, the outdoor air inlet channel 15 and the outdoor air outlet 17, the heat exchanger 30 is installed in the heat exchange space 19, and the blower 50 is installed in the indoor air supply channel 13.
The box body 10 can receive indoor high-temperature airflow through the indoor air inlet channel 11 and can receive outdoor low-temperature airflow through the outdoor air inlet channel 15; after the indoor high-temperature airflow and the outdoor low-temperature airflow are subjected to heat exchange, the indoor high-temperature airflow is converted into the indoor low-temperature airflow, the outdoor low-temperature airflow is converted into the outdoor high-temperature airflow, the box body 10 can convey the indoor low-temperature airflow back to the indoor through the indoor air supply channel 13, and the outdoor high-temperature airflow can be discharged to the external environment through the outdoor air outlet 17. The terms "high temperature" and "low temperature" refer to different temperature states of the same airflow, for example, when the indoor high temperature airflow is cooled, the cooled indoor high temperature airflow may be referred to as indoor low temperature airflow; for example, when the outdoor low-temperature airflow is heated, the heated outdoor low-temperature airflow may be referred to as outdoor high-temperature airflow.
The cooling unit 100 can utilize the blower 50 to drive the air flow to flow, so that the indoor air supply channel 13 and the indoor air intake channel 11 form negative pressure, which helps to promote the indoor high-temperature air flow to enter the indoor air intake channel 11 and promote the indoor low-temperature air flow to flow back to the indoor from the indoor air supply channel 13. In addition, in the case that the cooling unit 100 may further include the exhaust fan 51, the exhaust fan 51 may be installed outside the cabinet 10 and directed toward the outdoor exhaust outlet 17, and the outdoor exhaust outlet 17 may communicate with the external environment through an exhaust duct. The exhaust fan 51 can drive the airflow to flow, so that the outdoor air inlet channel 15 forms negative pressure, which is beneficial to promoting the outdoor low-temperature airflow to enter the outdoor air inlet channel 15 and promoting the outdoor high-temperature airflow to be exhausted from the outdoor air outlet 17 to the external environment; and because the box body 10 is provided with the outdoor air outlet 17 and is not provided with an air exhaust channel, the flow path of outdoor high-temperature air flow can be effectively shortened, and the energy consumption of the exhaust fan 51 is reduced.
Indoor inlet air channel 11 can run through box 10 and form indoor air intake (not shown) at the lateral wall of box 10, because the lateral wall of box 10 is located to indoor air intake, not only can help the area of indoor air intake to set up comparatively widely to do benefit to indoor inlet air channel 11 and receive indoor high temperature air current, but also help cooling unit 100 to be suitable for and install in the indoor environment that highly is restricted, avoided indoor air intake to set up in the roof 102 of box 10 and lead to roof 102 and the indoor roof of box 10 too close to, hinder indoor inlet air channel 11 and receive the condition of indoor high temperature air current then.
Indoor air supply channel 13 can run through box 10 and form indoor supply-air outlet 18 at the lateral wall of box 10, because indoor supply-air outlet 18 locates the lateral wall of box 10, not only help indoor supply-air outlet 18 the area can be seted up comparatively widely, so as to be favorable to indoor air supply channel 13 to carry indoor low temperature air current back to indoor, but also help cooling unit 100 to be suitable for and install in the indoor environment of height restriction, avoided indoor supply-air outlet 18 to set up in the roof 102 of box 10 and lead to roof 102 and the indoor roof of box 10 too close to, then hinder indoor supply-air channel 13 to carry the condition of indoor low temperature air current.
The indoor air supply channel 13 facilitates the cooling unit 100 to flexibly select the external cooling type cold source for compensation and installation in the indoor air supply channel 13, so that the external cooling type cold source can further cool the indoor low-temperature air flow, thereby facilitating the improvement of the cooling effect of the cooling unit 100.
The indoor air supply outlet 18 and the indoor air inlet may be located on different side walls of the housing 10, which helps to reduce the situation that the indoor air supply outlet 18 and the indoor air inlet are located too close to each other due to being located on the same side wall, which in turn causes mutual interference between the air flows in the vicinity of the indoor air supply outlet and the indoor air inlet, and helps the cooling unit 100 to more stably receive the indoor high-temperature air flow and more stably convey the indoor low-temperature air flow back to the indoor space. In this embodiment, the indoor air supply outlet 18 and the indoor air inlet may be located on two adjacent side walls of the box 10.
In some embodiments, the indoor supply air outlet 18 may be formed in the bottom wall 103 of the cabinet 10, which helps the cooling unit 100 to deliver the indoor low temperature air flow to the indoor floor.
The outdoor air inlet channel 15 may penetrate through the box 10 and form a first outdoor air inlet 14 and a second outdoor air inlet 16 on the side wall of the box 10, and the first outdoor air inlet 14 and the second outdoor air inlet 16 may be respectively communicated with the external environment through respective air pipes. The first outdoor air inlet 14 and the second outdoor air inlet 16 may be located on the same side wall, and the first outdoor air inlet 14 and the second outdoor air inlet 16 may be respectively communicated with the external environment through respective air pipes, or may be communicated with the external environment through the same air pipe; the first outdoor air inlet 14 and the second outdoor air inlet 16 are communicated with the external environment through the same air duct, which helps to reduce the number of air ducts.
The outdoor air inlet channel 15 facilitates the cooling unit 100 to flexibly select an external cooling type cold source for compensation and installation in the outdoor air inlet channel 15, so that the external cooling type cold source can further cool the outdoor low-temperature air flow, thereby facilitating the improvement of the cooling effect of the cooling unit 100.
The first outdoor air inlet 14 and the indoor air inlet may be located on different side walls, and the second outdoor air inlet 16 and the indoor air inlet are also located on different side walls, which helps to prevent the indoor air inlet and the first outdoor air inlet 14 (or the second outdoor air inlet 16) from being blocked by the air pipe due to being located on the same side wall, and then the indoor air inlet is blocked from receiving the indoor high-temperature air flow, thereby helping the cooling unit 100 to more stably receive the indoor high-temperature air flow.
The first outdoor air inlet 14 and the indoor air inlet 18 may also be located on different side walls, and then the second outdoor air inlet 16 and the indoor air inlet 18 are also located on different side walls, which helps to prevent the indoor air inlet 18 and the first outdoor air inlet 14 (or the second outdoor air inlet 16) from blocking the indoor air inlet 18 due to the air duct being located on the same side wall, and then block the indoor air inlet 18 from conveying indoor low-temperature airflow back to the room, thereby helping the cooling unit 100 to more stably convey indoor low-temperature airflow back to the room.
The outdoor air inlet channel 15 may include a first outdoor air inlet channel 151 and a second outdoor air inlet channel 153, and the first outdoor air inlet channel 151 is communicated between the heat exchanging space 19 and the second outdoor air inlet channel 153. The first outdoor air inlet channel 151 is communicated with the first outdoor air inlet 14, so that the outdoor low-temperature air flow can enter the heat exchanger 30 located in the heat exchange space 19 from the first outdoor air inlet 14 through the first outdoor air inlet channel 151. The second outdoor air inlet 16 is communicated with the second outdoor air inlet channel 153, so that the outdoor low-temperature air flow can also enter the heat exchanger 30 located in the heat exchange space 19 from the second outdoor air inlet 16 through the second outdoor air inlet channel 153 and the first outdoor air inlet channel 151.
The first outdoor air inlet channel 151 and the second outdoor air inlet channel 153 extend in different directions, so that the outdoor air inlet channel 15 is a non-straight channel, which helps to buffer the flow rate of the outdoor low-temperature air flow entering the outdoor air inlet channel 15 from the second outdoor air inlet 16. In this embodiment, the first outdoor air inlet channel 151 and the second outdoor air inlet channel 153 may extend in a direction perpendicular to each other.
The heat exchanger 30 may be a plate heat exchanger. The heat exchanger 30 includes an indoor air intake side 31, an indoor air supply side 33, an outdoor air intake side 35, and an outdoor air discharge side 37, the indoor air intake side 31 facing the indoor air intake duct 11, the indoor air supply side 33 facing the indoor air supply duct 13, the outdoor air intake side 35 facing the outdoor air intake duct 15, and the outdoor air discharge side 37 facing the outdoor air discharge outlet 17. The heat exchanger 30 can heat-exchange the indoor high-temperature air stream received from the indoor air intake side 31 with the outdoor low-temperature air stream received from the outdoor air intake side 35, so that the heat-exchanged indoor high-temperature air stream is converted into the indoor low-temperature air stream and output from the indoor air supply side 33, and the heat-exchanged outdoor low-temperature air stream is converted into the outdoor high-temperature air stream and output from the outdoor air discharge side 37.
In addition, the indoor air inlet side 31 of the heat exchanger 30 is adjacent to the indoor air inlet channel 11, which can shorten the flow path of the indoor high-temperature air flow, thereby helping to reduce the energy consumption of the blower 50. The outdoor discharge side 37 of the heat exchanger 30 may also be in close proximity to the outdoor discharge outlet 17, also helping to reduce the power consumption of the discharge fan 51.
The structure of the cabinet 10 can be adjusted to fit the heat exchanger 30 to the heat exchanging space 19. For example, the housing 10 may further include a supporting frame 101, the supporting frame 101 may be located between the top wall 102 and the bottom wall 103 of the housing 10, and the supporting frame 101 may support the heat exchanger 30 from the outdoor air inlet side 35, so that the heat exchanger 30 may be stably placed on the supporting frame 101, and the heat exchanger 30 may be fixed to the supporting frame 101 without using a complicated fixing method for the heat exchanger 30.
Due to the improvement of the design layout of the cooling unit 100, the unit structure is more compact, the airflow organization is better, the phenomenon of water floating outside the room is further avoided, the resistance of indoor high-temperature airflow flowing in the indoor air inlet channel 11 can be effectively reduced, the resistance of indoor low-temperature airflow flowing in the indoor air supply channel 13 is reduced, the resistance of outdoor low-temperature airflow flowing in the outdoor air inlet channel 15 is reduced, and the flows of the indoor high-temperature airflow, the indoor low-temperature airflow and the outdoor low-temperature airflow are smoother. In addition, the cooling unit 100 with a compact structure also helps to reduce the energy consumption of the blower 50 and the exhaust fan 51.
The cooling unit 100 may further include a bypass damper 70, and the bypass damper 70 may be installed at the first outdoor air inlet 14. The bypass damper 70 can adjust the airflow rate of the outdoor low-temperature airflow flowing through the first outdoor air inlet 14, for example, when the bypass damper 70 is in a closed state, the outdoor low-temperature airflow cannot enter the outdoor air inlet passage 15 through the first outdoor air inlet 14. For another example, when the bypass damper 70 is in the open state, the outdoor low-temperature airflow may enter the outdoor intake duct 15 through the first outdoor intake opening 14.
The cooling unit 100 may further include a heat dissipation filler 90, the heat dissipation filler 90 may be installed at the second outdoor air inlet 16, and the heat dissipation filler 90 helps to reduce the temperature of the outdoor low-temperature air flow passing through the heat dissipation filler and helps to increase the humidity of the outdoor low-temperature air flow, so as to help to increase the heat exchange effect between the outdoor low-temperature air flow and the indoor high-temperature air flow, and thus the indoor high-temperature air flow after heat exchange is converted into an indoor low-temperature air flow with a lower temperature. The heat dissipation filler 90 may be a material having high (hydrophilic) absorptivity.
In addition, because the heat dissipation filler 90 is installed at the second outdoor air inlet 16, and the extending direction of the second outdoor air inlet channel 153 is different from that of the first outdoor air inlet channel 151, the outdoor low-temperature air flow entering the outdoor air inlet channel 15 from the second outdoor air inlet 16 is blocked to reduce the flow speed of the outdoor low-temperature air flow, so that the contact time between the outdoor low-temperature air flow and the heat dissipation filler 90 is prolonged, and the cooling effect of the heat dissipation filler 90 on the outdoor low-temperature air flow is further improved.
Based on the fact that the airflow always flows along the flow channel with small airflow resistance, the bypass air valve 70 can influence the condition that the outdoor low-temperature airflow enters the outdoor air inlet channel 15 from the second outdoor air inlet 16 by adjusting the opening degree of the bypass air valve. For example, when the opening degree of the bypass vent valve 70 is larger, the flow rate of the outdoor low-temperature air entering the outdoor air inlet channel 15 through the second outdoor air inlet 16 is smaller; for example, the smaller the opening degree of the bypass vent valve 70, the larger the flow rate of the outdoor low-temperature air entering the outdoor air intake passage 15 through the second outdoor air intake 16.
The cooling assembly 100 may further include a spray assembly 20, the spray assembly 20 may be located above the heat sink 90, and a spray head of the spray assembly 20 may face the heat sink 90. The spray assembly 20 is selectively in a spray state or an off state, and a user can adjust the state of the spray assembly 20 according to the actual desired cooling effect. When the spray assembly 20 is in the spray state, the water sprayed from the spray assembly 20 can lower the temperature of the heat dissipation filler 90, and then can lower the temperature of the outdoor low-temperature air flow entering the outdoor air inlet channel 15 through the second outdoor air inlet 16. Spray assembly 20 may stop spraying water when spray assembly 20 is in the off state.
The cooling assembly 100 may further include a water tank 40, and a water pump 60, wherein the water tank 40 may be located below the heat sink 90, and the water pump 60 may communicate the water tank 40 with the spray assembly 20. The reservoir 40 can receive water from the spray assembly 20 and also can receive water dripping from the heat sink 90, and the water pump 60 can re-deliver the water in the reservoir to the spray assembly 20 to help improve water utilization.
The water storage tank 40, the first outdoor air inlet 14 and the second outdoor air inlet 16 may be sequentially distributed from the bottom wall 103 of the box 10 along the direction of the top wall 102, so that the first outdoor air inlet 14 is closer to the water storage tank 40 than the second outdoor air inlet 16, and the water storage tank 40 may be an open water storage tank, which facilitates the outdoor low-temperature air flow entering the outdoor air inlet channel 15 from the first outdoor air inlet 14 to contact with the water in the water storage tank 40 when flowing through the water storage tank 40, thereby facilitating the reduction of the temperature of the outdoor low-temperature air flow.
The cooling unit 100 may further include a liquid cooling coil 80, and the medium loaded in the liquid cooling coil 80 may be cold water, which is helpful for the cooling unit 100 to flexibly select the liquid cooling coil 80 as compensation of an external cooling type cold source with a practically required cooling effect. Liquid cooling coil 80 may be located between blower 50 and indoor blower side 33, and liquid cooling coil 80 may exchange heat with the airflow passing therethrough, such that the temperature of the airflow is reduced, thereby helping to further reduce the temperature of the indoor low temperature airflow. The liquid cooling coil 80 may be in close proximity to the indoor supply side 33 of the heat exchanger 30, thereby reducing the possibility that the low temperature indoor air flowing from the indoor supply side may flow directly back into the room without being cooled by the liquid cooling coil 80.
The cooling unit 100 of the present application can adopt different air intake modes to adjust its own heat dissipation effect.
When the external environment temperature is low, the cooling unit 100 may be in a first air intake mode, in which on one hand, external low-temperature air flow mainly enters the first outdoor air intake channel 151 from the first outdoor air intake 14 of the box 10, and enters the heat exchanger 30 through the outdoor air intake side 35 of the heat exchanger 30; on the other hand, the indoor high-temperature air flow enters the indoor air inlet channel 11 from the indoor air inlet of the box body 10 and enters the heat exchanger 30 through the indoor air inlet side 31 of the heat exchanger 30. After the heat exchanger 30 exchanges heat between the indoor high-temperature airflow and the outdoor low-temperature airflow, the indoor low-temperature airflow is delivered from the indoor air supply side 33 of the heat exchanger 30 back to the indoor through the indoor air supply channel 13, and the outdoor high-temperature airflow is discharged from the outdoor air discharge side 37 of the heat exchanger 30 through the outdoor air discharge outlet 17, which may be referred to as a pure natural cooling mode of the cooling unit 100.
When the cooling unit 100 cannot meet the heat dissipation requirement in the first air intake mode, the cooling unit 100 may be in the second air intake mode, the opening degree of the bypass air valve 70 is smaller than that in the first air intake mode, the spray assembly 20 may be in the spray state, the outdoor low-temperature air flow mainly enters the second outdoor air intake channel 153 from the second outdoor air intake 16 of the box body 10, the outdoor low-temperature air flow passes through the heat dissipation filler 90 and the water sprayed by the spray assembly 20 to be cooled, and then sequentially passes through the second outdoor air intake channel 153 and the first outdoor air intake channel 151 and enters the heat exchanger 30 from the outdoor air intake side 35 of the heat exchanger 30 to exchange heat with the indoor high-temperature air flow, so that the temperature of the indoor low-temperature air flow flowing out from the indoor air supply side 33 of the heat exchanger 30 is lower, which may be referred to as an indirect evaporative cooling mode of the cooling unit 100.
When the heat dissipation effect of the cooling unit 100 needs to be further enhanced, the liquid-cooling coil 80 can be further opened under the condition that the cooling unit 100 is kept in the second air inlet mode, so as to further cool the indoor low-temperature air flow, which may be referred to as an indirect evaporative cooling and low-temperature coil compensation mode of the cooling unit 100.
The present embodiment provides an air conditioning system (not shown), which includes the cooling unit 100 according to any one of the above embodiments.
In the air conditioning system provided by the embodiment of the application, the cooling unit 100 can be installed indoors, and the heat exchange space 19 of the box body 10 is respectively communicated with the indoor air inlet channel 11, the indoor air supply channel 13, the outdoor air inlet channel 15 and the outdoor air outlet 17; the heat exchanger 30 is installed in the heat exchange space 19, the indoor air inlet side 31 of the heat exchanger 30 faces the indoor air inlet channel 11, the indoor air supply side 33 faces the indoor air supply channel 13, the outdoor air inlet side 35 faces the outdoor air inlet channel 15, and the outdoor air outlet side 37 faces the outdoor air outlet 17; the blower 50 is located in the indoor air supply channel 13, and the blower 50 can drive the air flow to flow, so that the indoor high-temperature air flow can enter the radiator from the indoor air inlet side 31 through the indoor air inlet channel 11 to perform heat exchange and temperature reduction, and the indoor high-temperature air flow is converted into the indoor low-temperature air flow and then enters the room again from the indoor air supply side 33 of the radiator through the indoor air supply channel 13. The design layout of the cooling unit 100 is improved, so that the unit structure is more compact, the airflow organization is better, the water floating phenomenon on the outdoor side is further avoided, the resistance of indoor high-temperature airflow flowing in the indoor air inlet channel 11 can be effectively reduced, the resistance of indoor low-temperature airflow flowing in the indoor air supply channel 13 is reduced, the resistance of outdoor low-temperature airflow flowing in the outdoor air inlet channel 15 is reduced, the flows of the indoor high-temperature airflow, the indoor low-temperature airflow and the outdoor low-temperature airflow are smoother, the indoor air inlet side 31 of the heat exchanger 30 is closely adjacent to the indoor air inlet channel 11, the flowing path of the indoor high-temperature airflow can be shortened, and the energy consumption of the blower 50 is reduced. In addition, since the case 10 has the indoor air supply channel 13 and the outdoor air intake channel 15, the cooling unit 100 is facilitated to flexibly select the external cooling type cold source for compensation and install in at least one of the two channels, thereby facilitating to improve the cooling effect of the cooling unit 100.
