Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation in computer rooms, in particular to a heat dissipation system for a data center. Background Art

[0002] A data center is a physical room, building or facility that hosts IT infrastructure for building, running and delivering applications and services, and for storing and managing data associated with those applications and services.

[0003] Since a large number of electronic devices are installed in the data center, a large amount of heat will be generated during the operation of the electronic devices. In order to reduce the heat in the data center so as to facilitate the stable operation of the electronic devices, the heat inside the data center is often dissipated. As recorded in the text of the Chinese patent publication number CN102458084B entitled Data Center and Its Heat Dissipation System, cold air is generated by refrigeration equipment and transported to the data center through ventilation pipes to achieve good heat dissipation of the data center. In actual implementation, in order to ensure a good working environment for the staff in the data center, it is usually necessary to maintain positive pressure in the data center and maintain a state of sufficient oxygen. Therefore, the air in the data center is often in a state of circulation with the external atmosphere. Obviously, when the air temperature in the data center is lower than that of the outside world, in order to ensure the stability of the temperature of the data center, it is necessary to continuously cool the air entering the data center from the outside world, and then the refrigeration equipment needs to maintain high-power operation for a long time, which consumes a lot of energy, so it needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a data center heat dissipation system, which can not only realize air circulation, but also ensure the temperature stability of the data center on the basis of reducing energy consumption.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A data center heat dissipation system includes a machine room and a condenser for cooling the air in the machine room. The machine room is equipped with an exhaust duct and an air supply duct to exhaust air to the outside and to supply air to the inside respectively. A heat exchange box with an open top is arranged beside the machine room. Coolant is arranged in the heat exchange box, and the exhaust end of the exhaust duct is inserted into the coolant. The air supply duct runs through the heat exchange box, and the pipe body of the air supply duct located in the heat exchange box is placed in the coolant.

[0007] As a further solution of the utility model: a heat exchange plate is installed on a section of the air supply pipe located in the coolant, and the heat exchange plate is used to increase the heat exchange stroke and heat exchange area between the air and the coolant.

[0008] As a further solution of the utility model: the plate surface of the heat exchange plate is distributed vertically, and the heat exchange plate is distributed in an S shape in a top view, and a spoiler jet plate connected to the output end of the air supply pipe is arranged between the bottom of the heat exchange plate and the bottom of the heat exchange box, the plate surface of the spoiler jet plate is distributed horizontally, and the upper plate surface of the spoiler jet plate is provided with a plurality of jet holes distributed in a dot matrix.

[0009] As a further solution of the utility model: the exhaust duct is provided with two exhaust ends, and the two output ends are respectively a first exhaust end and a second exhaust end, the first exhaust end is inserted into the coolant, the second exhaust end is discharged to the outside, and control valves are installed on both the first exhaust end and the second exhaust end.

[0010] As a further solution of the utility model: the top and bottom of the machine room are respectively set as an air supply chamber and an exhaust chamber, and the air supply chamber and the exhaust chamber are connected with the machine room through a plurality of through holes distributed in a dot matrix in a vertical viewing angle, the air supply chamber and the exhaust chamber are respectively connected with the air supply pipe and the exhaust pipe, and the condenser is installed on the pipe body of the air supply pipe between the air supply chamber and the heat exchange box.

[0011] As a further solution of the utility model: the exhaust duct includes an exhaust fan installed on the duct body, and the air supply duct includes an air supply fan installed on the duct body.

[0012] As a further solution of the utility model: an air filter is installed at the air inlet end of the air supply pipe.

[0013] As a further solution of the utility model: a pressure relief pipe is installed on the top of the heat exchange box, and the pipe mouth of the pressure relief pipe constitutes the top opening of the heat exchange box.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the outdoor air temperature is higher than the temperature in the machine room, the exhaust end of the air supply pipe guides the cold air in the machine room, which is lower than the outdoor temperature, into the coolant in the heat exchange box. After the cold air exchanges heat with the coolant and heats up, it is discharged outward through the top opening of the heat exchange box, and the coolant is used to recover the cold energy. Since the air supply pipe runs through the heat exchange box, and the pipe body of the air supply pipe located in the heat exchange box is placed in the coolant, the cold energy recovered by the coolant can be used to cool the air sent into the machine room by the air supply pipe, reducing the temperature difference between the air delivered to the machine room and the original air in the machine room, so that the machine room can not only realize air circulation, but also reduce the working energy consumption of the condenser under the premise of ensuring the temperature stability of the data center.

[0016] 2. A heat exchange plate is installed on a section of the air supply pipe located in the coolant. The heat exchange plate is used to increase the heat exchange stroke and heat exchange area between the air and the coolant, thereby further improving the cooling effect on the air in the air supply pipe.

[0017] 3. A spoiler jet plate connected to the output end of the air supply pipe is arranged between the bottom of the heat exchange plate and the bottom of the heat exchange box. The spoiler jet plate surface is horizontally distributed, and the upper surface of the spoiler jet plate is provided with a plurality of jet holes distributed in a dot matrix, so that the cold air transported by the air supply pipe is uniformly transported upward to the coolant through the plurality of jet holes on the upper surface of the spoiler jet plate, thereby ensuring the uniformity of cooling the coolant. In addition, since the surface of the heat exchange plate is vertically distributed, and the heat exchange plate is S-shaped in a top-down perspective, the cold air ejected upward from the spoiler jet plate will flow along the surface of the heat exchange plate, thereby ensuring a good and uniform cooling effect on the coolant on the periphery of the surface of the heat exchange plate, thereby achieving a good cooling effect on the air in the heat exchange plate.

[0018] 4. The exhaust duct is provided with two exhaust ends. When the outdoor air temperature is lower than the temperature in the machine room, the control valve on the second exhaust end can be opened and the control valve on the first exhaust end can be closed, so that the gas in the exhaust duct can be directly discharged into the atmosphere, thereby avoiding the temperature rise of the coolant in the exhaust duct.

[0019] 5. The top and bottom of the machine room are respectively set as the air supply chamber and the exhaust chamber, and the air supply chamber and the exhaust chamber are connected to the machine room through holes distributed in a dot matrix in a vertical angle of view. The air supply chamber and the exhaust chamber are connected to the air supply pipe and the exhaust pipe respectively. The condenser is installed on the pipe body between the air supply chamber and the heat exchange box on the air supply pipe, so that the cold air cooled by the heat exchange box and the condenser and transported to the air supply chamber can be evenly transported to the machine room. In addition, due to the principle of hot air rising, it is also convenient for relatively hot gas to enter the exhaust chamber and be discharged outside.

[0020] 6. The exhaust duct includes an exhaust fan installed on the duct body, and the supply duct includes a supply fan installed on the duct body. The simultaneous operation of the exhaust fan and the supply fan effectively ensures that the air pressure in the machine room is relatively close to normal pressure, which is beneficial to ensure the stable operation of components such as the chassis in the machine room, and also improves the comfort of the staff in the machine room.

[0021] 7. An air filter is installed at the air inlet end of the air supply duct, which filters the air delivered to the machine room to ensure the cleanliness of the air in the machine room.

[0022] 8. A pressure relief pipe is installed on the top of the heat exchanger box, and the pipe mouth of the pressure relief pipe constitutes the top opening of the heat exchanger box. In the specific implementation, a pressure relief pipe with a suitable diameter can be selected to reduce the loss of cold energy in the heat exchanger box while ensuring good pressure relief of the heat exchanger box.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0029] The specific structure of the utility model refers to Figure 1-3 As shown, its main structure includes a machine room 10 and a condenser 40 for cooling the air in the machine room 10. The machine room 10 exhausts air to the outside and delivers air to the inside through the exhaust pipe 21 and the air supply pipe 31, respectively. A heat exchange box 50 with a top opening is arranged beside the machine room 10. Coolant 53 is arranged in the heat exchange box 50, and the exhaust end of the exhaust pipe 21 is inserted into the coolant 53. When the outdoor air temperature is higher than the temperature in the machine room 10, the exhaust end of the air supply pipe 31 guides the cold air in the machine room 10, which is lower than the outdoor temperature, into the coolant 53 in the heat exchange box 50. After the cold air exchanges heat with the coolant 53 and heats up, it is discharged to the outside through the top opening of the heat exchange box 50, and the cold energy is recovered through the coolant 53. Since the air supply pipe 31 runs through the heat exchange box 50, and the tube body of the air supply pipe 31 located in the heat exchange box 50 is placed in the coolant 53, the cold energy recovered by the coolant 53 can be used to cool the air sent into the machine room 10 by the air supply pipe 31, thereby reducing the temperature difference between the air delivered to the machine room 10 and the original air in the machine room 10, so that the machine room 10 can not only realize air circulation, but also reduce the working energy consumption of the condenser 40 while ensuring the temperature stability of the data center.

[0030] Specifically, Figure 1As shown, a pressure relief pipe 52 is installed on the top of the heat exchanger box 50, and the pipe mouth of the pressure relief pipe 52 constitutes the top opening of the heat exchanger box 50. In specific implementation, a pressure relief pipe 52 of a suitable diameter can be selected to reduce the loss of cold energy in the heat exchanger box 50 while ensuring good pressure relief of the heat exchanger box 50.

[0031] On the basis of the above, if Figure 2 As shown, a heat exchange plate 32 is installed on a section of the air supply pipe 31 located in the coolant 53. The heat exchange plate 32 is used to increase the heat exchange stroke and heat exchange area between the air and the coolant 53, thereby further improving the cooling effect of the air in the air supply pipe 31. Figure 3 As shown, a spoiler jet plate 51 connected to the output end of the air supply pipe 31 is arranged between the bottom of the heat exchange plate 32 and the bottom of the heat exchange box 50, the spoiler jet plate 51 is horizontally distributed, and the upper plate surface of the spoiler jet plate 51 is provided with a plurality of jet holes distributed in a dot matrix, so that the cold air transported by the air supply pipe 31 is uniformly transported upward to the coolant 53 through the plurality of jet holes on the upper plate surface of the spoiler jet plate 51, ensuring the uniformity of cooling the coolant 53. In addition, since the plate surface of the heat exchange plate 32 is vertically distributed, and the heat exchange plate 32 is S-shaped in a top view, the cold air ejected upward from the spoiler jet plate 51 will flow along the plate surface of the heat exchange plate 32, ensuring a good and uniform cooling effect on the coolant 53 on the outer periphery of the plate surface of the heat exchange plate 32, thereby achieving a good cooling effect on the air in the heat exchange plate 32.

[0032] On the basis of the above, if Figure 1 As shown, the exhaust pipe 21 is provided with two exhaust ends, and the two output ends are respectively the first exhaust end 211 and the second exhaust end 212. The first exhaust end 211 is inserted into the coolant 53, and the second exhaust end 212 is discharged outdoors. The first exhaust end 211 and the second exhaust end 212 are both installed with control valves 23, thereby realizing dual-channel exhaust of the exhaust pipe 21. In specific implementation, when the outdoor air temperature is lower than the temperature in the machine room 10, the weather temperature is low, or the temperature in the machine room 10 and the condenser 40 is high during the initial startup process, the control valve 23 on the second exhaust end 212 can be opened, and the control valve 23 on the first exhaust end 211 can be closed, so that the gas in the exhaust pipe 21 is directly discharged into the atmosphere, thereby avoiding the coolant 53 in the exhaust pipe 21 from heating up.

[0033] On the basis of the above, if Figure 1As shown, the top and bottom of the machine room 10 are respectively set as the air supply chamber 30 and the exhaust chamber 20, and the air supply chamber 30 and the exhaust chamber 20 are connected to the machine room 10 through holes distributed in a dot matrix in a vertical angle of view, and the air supply chamber 30 and the exhaust chamber 20 are respectively connected to the air supply pipe 31 and the exhaust pipe 21, and the condenser 40 is installed on the pipe body between the air supply chamber 30 and the heat exchange box 50 on the air supply pipe 31, so that the cold air transported to the air supply chamber 30 after being cooled by the heat exchange box 50 and the condenser 40 can be evenly transported to the machine room 10. In addition, due to the principle that hot air rises, it is also convenient for relatively hot gas to enter the exhaust chamber 20 and be discharged outward.

[0034] On the basis of the above, if Figure 1 As shown, the exhaust duct 21 includes an exhaust fan 22 installed on the tube body, and the supply air duct 31 includes a supply air fan 33 installed on the tube body. Through the simultaneous operation of the exhaust fan 22 and the supply air fan 33, the air pressure in the machine room 10 is effectively guaranteed to be relatively close to normal pressure, which is beneficial to ensuring the stable operation of components such as the chassis in the machine room 10 and also improves the comfort of the staff in the machine room 10.

[0035] It is worth mentioning that Figure 1 As shown, an air filter 34 is installed at the air inlet end of the air supply pipe 31 , and the air supplied to the machine room 10 is filtered by the air filter 34 , thereby ensuring that the air in the machine room 10 is clean.
