[0001] The utility model relates to the technical field of refrigeration, in particular to a high-density and IDC computer room air-conditioning cooling device. Background Art

[0002] An IDC computer room is an Internet data center that has multiple servers built in for Internet data storage and transmission. In this data center, due to the large number of servers and high density, the high-density servers generate a lot of heat when working, resulting in a high temperature in the computer room. Therefore, the data center computer room needs to use air-conditioning cooling devices to achieve the purpose of cooling and cooling, to ensure the normal operation of the equipment, and to avoid equipment damage caused by excessive temperature.

When the device is in use, the temperature is detected by the temperature sensor, and the air conditioning host generates cold air through refrigeration and stores it in the storage box. In the data center, the cold air is diverted through the diversion rack to the space of the data center to achieve the purpose of cooling and cooling. Although the above device can achieve cooling and cooling, there are still great inconveniences in the use of the above device: since the data center space is large, and the principle of refrigeration of the air-conditioning host is to compress the refrigerant into the condenser, and generate cold air through heat exchange in the condenser, and the refrigerant is circulated. After the refrigerant absorbs heat, it is cooled in the external heat exchange device. However, due to different seasons, the cooling effect required for the refrigerant is different, and the device in the prior art cannot adjust the cooling effect of the refrigerant according to the needs. For this reason, we propose an air conditioning cooling device for use in high-density and IDC computer rooms. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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. Example 1

[0030] like Figure 1 As shown, it is a structural schematic diagram of the air-conditioning cooling device in this embodiment. The air-conditioning cooling device in this embodiment is used in an IDC computer room with a large space and a high density. Since there are many devices in the IDC computer room and the density is large, the devices generate a large amount of heat when in use. Conventional air-conditioning refrigeration cannot achieve an ideal cooling effect. Therefore, in this embodiment, the above-mentioned air-conditioning cooling device is used to cool and cool the IDC space.

[0031] like Figure 1As shown, the air conditioning cooling device in this embodiment includes a refrigerator body 100, and a condenser is arranged in the refrigerator body 100. The condenser is used to cool the air entering the refrigerator body 100. In addition, the air conditioning cooling device in this embodiment is provided with an induced draft fan 101 at the top of the refrigerator body 100. The induced draft fan 101 rotates to lead out the cooled air in the refrigerator body 100, so as to cool the IDC room on a large scale. In this embodiment, the refrigerator body 100 is connected to a heat exchange tank 200 through a pipeline, and the heat exchange tank 200 is connected to the condenser through a pipeline. It is worth noting that the heat exchange tank 200 injects the refrigerant into the condenser through the pipeline, and the air is cooled in the condenser. Then, the refrigerator body 100 injects the refrigerant heated in the condenser due to heat exchange into the heat exchange tank 200 again through the pipeline and the compressor for heat exchange to achieve the purpose of cooling the refrigerant.

[0032] In addition, it is worth noting that a plurality of induced draft fans 101 are arranged on the top of the refrigerator body 100 in this embodiment. The induced draft fans 101 draw out the cooled air in the condenser to cool the IDC room. In this embodiment, since a plurality of induced draft fans 101 are arranged, when one of the induced draft fans 101 is damaged, it does not affect the other induced draft fans 101 from drawing out the cooled air in the condenser, thereby ensuring the use effect of the air conditioning cooling device.

[0033] In this embodiment, the refrigerant enters the condenser to generate heat exchange, causing the temperature of the refrigerant to increase. In order to achieve refrigerant cooling, the air-conditioning cooling device in this embodiment is also provided with a heat exchange tank 200. The refrigerant enters the heat exchange tank 200 and the temperature of the refrigerant is reduced through heat exchange, so that it can enter the condenser again to achieve the purpose of cooling the air.

[0034] like Figures 2~4 As shown, it is a structural schematic diagram of the heat exchange tank 200 in this embodiment. The heat exchange tank 200 in this embodiment includes an upper shell 201 and a lower shell 202. The upper shell 201 and the lower shell 202 are detachably connected and the upper shell 201 can be moved relative to the lower shell 202 to change the size of the cavity of the heat exchange tank 200. The refrigerant in this embodiment enters the heat exchange tank 200 through a pipeline and is discharged from the heat exchange tank 200 through a pipeline. When the volume of the heat exchange tank 200 changes, the residence time of the refrigerant in the heat exchange tank 200 changes, and then the cooling time of the refrigerant can be adjusted according to different seasons, so as to adjust the amount of cooling medium required for cooling the refrigerant, so as to achieve the purpose of saving resources.

[0035] like Figure 3 as well as Figure 4As shown, the lower shell 202 and the upper shell 201 in this embodiment are assembled to form a heat exchange tank 200, and an adjustment component 300 is arranged in the heat exchange tank 200. The refrigerant passes through the condenser and enters the adjustment component 300 through a pipeline, and after heat exchange in the heat exchange tank 200, passes through the adjustment component 300 and is discharged from the heat exchange tank 200 through the exhaust port.

[0036] In this embodiment, Figure 3 As shown, in this embodiment, a plug-in groove 202a is provided at the end of the lower shell 202, and a plug-in interface 201a is provided at the end of the upper shell 201 relative to the lower shell 202. The plug-in interface 201a is sealed and plugged into the plug-in groove 202a to form a heat exchange tank 200, and a telescopic spring 203 is sleeved on the plug-in interface 201a. After the upper shell 201 is plugged into the lower shell 202, the telescopic spring 203 is in a compressed state, so that the upper shell 201 and the lower shell 202 are tightly assembled. In this embodiment, the power mechanism that drives the upper shell 201 and the lower shell 202 to move relative to each other can be a linear motion mechanism, such as a cylinder, etc., which will not be repeated in this embodiment. When the power mechanism drives the upper shell 201 to move relative to the lower shell 202, the telescopic spring 203 serves the purpose of buffering to facilitate the adjustment of the volume of the heat exchange tank 200.

[0037] like Figure 4 As shown, the inner cavity of the heat exchange tank 200 in this embodiment is divided by the adjustment component 300 to form buffer cavities 204 at the upper and lower ends and a heat exchange cavity 205 in the middle. A cooling medium is injected into the heat exchange cavity 205. The refrigerant enters the heat exchange tank 200 from the bottom and is located in the buffer cavity 204 at the lower end. Then, it passes through the adjustment component 300 to achieve the purpose of heat exchange and cooling, enters the buffer cavity 204 at the upper end, and is discharged. In this embodiment, the residence time of the refrigerant in the heat exchange tank 200 is changed and the amount of cooling medium is adjusted by adjusting the volume of the heat exchange tank 200, so that the air-conditioning cooling device in this embodiment is easy to adjust according to the season. For example, in summer, the volume of the heat exchange tank 200 is expanded, the residence time of the refrigerant is extended, and the amount of cooling medium is increased, so that the refrigerant has a better cooling effect. In winter, the volume of the heat exchange tank 200 is reduced, the residence time of the refrigerant is reduced, and the amount of cooling medium is reduced, so that the refrigerant does not need to perform excessive heat exchange operations in winter, thereby making the air-conditioning cooling device in this embodiment more practical. Example 2

[0038] Reference Figures 4 to 8, which is a schematic diagram of the structure of the adjustment component 300 in this embodiment. The difference between this embodiment and embodiment 1 is that the adjustment component 300 is a length-adjustable structure. In this embodiment, the adjustment component 300 includes a drainage tube 301, a drainage bucket 302 and a connecting ring 303. In this embodiment, the drainage tube 301 is a retractable structure, such as a bellows structure. In this embodiment, the drainage tube 301 is connected to the drainage bucket 302 at both ends and communicates with the inner cavity of the drainage bucket 302. The drainage bucket 302 is connected to the connecting ring 303. The connecting rings 303 at both ends of the drainage tube 301 are connected to the drainage bucket 302. The connecting ring 303 is respectively assembled on the inner wall of the upper shell 201 and the lower shell 202. After the refrigerant enters the heat exchange tank 200, it enters the buffer cavity 204 at the lower end, and then enters the drainage bucket 302 and the drainage tube 301 until it is discharged through the drainage bucket 302 and the buffer cavity 204 at the upper end. Therefore, when the upper shell 201 moves relative to the lower shell 202, the length of the drainage tube 301 shrinks, thereby changing the residence time of the refrigerant in the heat exchange tank 200, so as to adjust the heat exchange effect of the refrigerant according to the ambient temperature.

[0039] Since the drainage tube 301 in this embodiment adopts a bellows structure to achieve expansion and contraction, when the upper shell 201 is away from the lower shell 202, the drainage tube 301 in the adjustment component 300 can be driven to extend, and when the upper shell 201 is close to the lower shell 202, the bellows in the adjustment component 300 is difficult to contract. In order to solve this problem, this embodiment also provides Figure 8 The structure of the drainage tube 301 is shown in FIG. Figure 8 As shown, the drainage tube 301 in this embodiment is a telescopic tube 301a, and a return spring 301b is sleeved on the outside of the telescopic tube 301a, and the two ends of the return spring 301b are respectively connected to the drainage bucket 302. When the upper shell 201 moves away from the lower shell 202, the telescopic tube 301a extends and the return spring 301b stretches. When the upper shell 201 is close to the lower shell 202, the telescopic tube 301a shortens and the return spring 301b contracts. The above structure can effectively avoid the problem that the bellows cannot contract, thereby ensuring the use effect of the adjustment component 300.

[0040] Working principle: In the present invention, after the refrigerant is cooled in the heat exchange tank 200, it enters the condenser in the refrigerator body 100 to condense the air. The condensed air is led out through the induced draft fan 101 to cool the IDC room. Since the refrigerant flow rate in this embodiment is large, the effect of condensing the air is obvious, and the induced draft fan 101 can discharge the cooled air into the IDC room to facilitate cooling of a large area of ​​space. After absorbing heat in the condenser, the refrigerant in the present invention enters the adjustment component 300 of the heat exchange tank 200 to cool. When the ambient temperature is high in summer, by adjusting the upper shell 201 relative to the lower shell 202 The heat exchange tank 200 is kept away from the outside, so that the residence time of the refrigerant in the heat exchange tank 200 is prolonged, thereby ensuring the cooling effect of the refrigerant. When the ambient temperature is low in winter, the upper shell 201 is adjusted to be close to the lower shell 202, so that the residence time of the refrigerant in the heat exchange tank 200 is shortened, and there is no need to excessively cool down the temperature, resulting in a huge waste of resources due to the use of cooling medium. In the utility model, the residence time of the refrigerant in the heat exchange tank 200 is adjusted by adjusting the volume of the heat exchange tank 200, so that the air-conditioning cooling device in the utility model can be adjusted according to the seasonal temperature. Therefore, the air-conditioning cooling device in the utility model has better practicality.

[0041] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
