[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0027] Embodiment 1:

[0028] like Figures 1 to 3 As shown, a modular data center dry cooler provided by Embodiment 1 of the utility model includes a plurality of heat dissipation devices 1;

[0029] The heat dissipation device 1 includes a base 11, a bottom plate 12, a front plate 13, a rear plate 14, a top plate 15, two partition-type radiators 16 and a fan 17; the bottom plate 12 is horizontally fixed on the base 11; the front plate 13 and the rear plate 14 are vertically fixed on the bottom plate 12; the top plate 15 is horizontally arranged and fixed with the front plate 13 and the rear plate 14; a vent 151 is provided on the top plate 15 for the fan 17 to extract internal air; the fan 17 is arranged above the vent 151; the two partition-type radiators 16 are respectively arranged on the left and right sides of the top plate 15; the top plate 15, the bottom plate 12, the front plate 13 and the rear plate 14 are all detachably fixed to the partition-type radiators 16;

[0030] All heat dissipation devices 1 are closely arranged along the front-to-back direction;

[0031] It also includes two liquid inlet pipes 2 and two liquid outlet pipes 3 for transporting the coolant; the two liquid inlet pipes 2 are respectively located on the left and right sides of the heat dissipation device 1; the two liquid outlet pipes 3 are respectively located on the left and right sides of the heat dissipation device 1;

[0032] The partition-type radiator 16 includes a core 161, an upper head 162 and a lower head 163; the upper head 162 is fixed to the top of the core 161; the lower head 163 is fixed to the bottom of the core 161; the upper head 162 is connected to the adjacent liquid inlet main pipe 2, and the lower head 163 is connected to the adjacent liquid outlet main pipe 3.

[0033] When the modular data center dry cooler provided in Example 1 of the utility model is used, the liquid inlet main pipe 2 is connected to the water outlet of the data center, and the liquid outlet main pipe 3 is connected to the water inlet of the data center; the liquid inlet main pipe 2 transports the cooling liquid flowing into the water outlet of the data center to the partition radiators 16 located at the left and right ends of the heat dissipation device 1, and extracts the air inside the heat dissipation device through the fan 17 located at the top of the heat dissipation device 1. At this time, the air outside the heat dissipation device 1 flows into the heat dissipation device 1 because the fan 17 extracts the air inside the heat dissipation device 1. The air outside the heat dissipation device 1 flows into the heat dissipation device 1 from the partitions on the left and right ends of the heat dissipation device 1. The external air enters the interior of the heat dissipation device 1 through the outer fins of the partition-type radiator 16. When passing through the partition-type radiators 16 at the left and right ends of the heat dissipation device 1, the external air exchanges heat with the heat carried by the coolant in the partition-type radiator 16, so that the external air absorbs the heat of the coolant in the partition-type radiator 16, thereby achieving the effect of lowering the temperature of the coolant. The air sucked into the heat dissipation device 1 is discharged from the vent 151 through the fan 17 on the top of the heat dissipation device 1, and the coolant that has undergone heat exchange flows from the partition-type radiator 16 into the liquid outlet main pipe 3, and the coolant is re-delivered to the water inlet end of the data center through the liquid outlet main pipe 3.

[0034] The modular data center dry cooler provided in Example 1 of the utility model is provided with a plurality of heat dissipation devices 1, and all the heat dissipation devices 1 are closely arranged in the front-to-back direction, and the heat dissipation device 1 includes two partition wall radiators 16, and the two partition wall radiators 16 are located on the left and right sides of the heat dissipation device 1, and the partition wall radiator 16 includes a core 161, an upper head 162 and a lower head 163, and the upper head 162 is connected to the adjacent liquid inlet main pipe 2, and the lower head 163 is connected to the adjacent liquid outlet main pipe 3; the water outlet end of the data center is connected to the liquid inlet main pipe 2, and the coolant in the liquid inlet main pipe 2 enters the partition wall radiators 16 in a plurality of heat dissipation devices 1 for heat dissipation, and the coolant entering the partition wall radiator 16 from the liquid inlet main pipe 2 is separated and dissipated by a plurality of independent heat dissipation devices 1. Compared with the prior art in which the aluminum profile frame is extended to achieve the change and adjustment of the size of the dry cooler, assembling a plurality of heat dissipation devices 1 into a dry cooler is more convenient for management, assembly and transportation, and is convenient for temporarily adding more heat dissipation devices 1 to obtain a better heat dissipation effect, and when the heat dissipation device 1 appears In case of a fault, the overall heat dissipation effect of the dry cooler can be effectively avoided; at the same time, the top plate 15, the bottom plate 12, the front plate 13 and the rear plate 14 are all detachably fixed to the partition wall radiator 16; if a fault occurs in the partition wall radiator 16, the faulty partition wall radiator 16 can be removed in time, and the connecting channel between the liquid inlet main pipe 2 and the partition wall radiator 16 and the connecting channel between the liquid outlet main pipe 3 and the partition wall radiator 16 can be closed, and the faulty partition wall radiator 16 will not affect other working heat dissipation devices 1. The coil structure is integrated with the prior art, and the length of the coil is adjusted according to the size of the dry cooler. It is connected to the fins only through a heat exchange medium inlet pipe and a heat exchange medium outlet pipe. If the fins, the heat exchange medium inlet pipe or the heat exchange medium outlet pipe in the coil are damaged by external factors, the entire dry cooler cannot be used any more. By setting up multiple heat dissipation devices 1, a detachable partition radiator 16 is set on the heat dissipation device 1, and each partition radiator 16 is independently connected to the liquid inlet main pipe 2 and the liquid outlet main pipe 3, the risk resistance of the dry cooler can be improved.

[0035] The modular data center dry cooler provided in Example 1 of the utility model is preferably configured such that the top of the partition wall radiator 16 on the left side is tilted to the left side compared to the bottom; the top of the partition wall radiator 16 on the right side is tilted to the right side compared to the bottom; the two partition wall radiators 16 are configured in a V shape;

[0036] The two partition wall radiators 16 are arranged in a V-shape. Compared with arranging the two partition wall radiators 16 vertically to the bottom plate 12, the V-shape arrangement can use a partition wall radiator 16 with a larger area. The partition wall radiator 16 with a larger area can generate a larger contact area with the air at the same time, thereby improving the heat dissipation efficiency.

[0037] In the modular data center dry cooler provided in Example 1 of the utility model, preferably, the liquid inlet main pipe 2 is located above the liquid outlet main pipe 3, the coolant in the partition wall radiator 16 flows along the up and down direction of the core 161, and the air flows through the core 161 along the front and back direction of the core 161, and the upper head 162 is detachably fixed to the top plate 15, and the lower head 163 is detachably fixed to the bottom plate 12, so that the upper head 162 is connected to the liquid inlet main pipe 2, and the lower head 163 is connected to the liquid outlet main pipe 3;

[0038] When the coolant from the water outlet of the data center is transported from the liquid inlet main pipe 2, the coolant flows into the upper head 162 from the liquid inlet main pipe 2, and flows from the upper head 162 to the lower head 163 from high to low, and enters the liquid outlet main pipe 3 from the lower head 163 after heat dissipation. The flow direction of the coolant in the partition type radiator 16 is from high to low. The setting of this flow direction speeds up the time required for the coolant to circulate in the partition type radiator 16, thereby improving the circulation and heat dissipation efficiency of the coolant between the dry cooler and the data center.

[0039] like Figure 4 As shown, the modular data center dry cooler provided by Example 1 of the utility model, preferably, a receiving member 121 is provided on the top of the bottom plate 12; the receiving member 121 includes a trough body 1211 without front and rear side walls, a left pad 1212, a left baffle 1213, a right pad 1214 and a right baffle 1215; the top of the left side wall of the trough body 1211 is connected and fixed to the right side of the left pad 1212, and the left side of the left pad 1212 is vertically fixed to the left baffle 1213; the left pad 1212 is arranged obliquely to the bottom plate 12; the top of the right side wall of the trough body 1211 is connected and fixed to the left side of the right pad 1214, and the right side of the right pad 1214 is vertically fixed to the right baffle 1215; the right pad 1214 is arranged obliquely to the bottom plate 12;

At this time, the bottom of the partition wall radiator 16 on the left side is placed vertically on the left pad 1212 and contacts with the left baffle 1213. The left pad 1212 receives the partition wall radiator 16 on the left side, and the left baffle 1213 limits the bottom of the partition wall radiator 16 on the left side. The left pad 1212 is set obliquely to the bottom plate 12 so that the partition wall radiator 16 on the left side can be The top of the radiator 16 is tilted to the left compared to the bottom, so that a larger volume of the partition-type radiator 16 can be used to improve the heat dissipation capacity; similarly, the bottom of the partition-type radiator 16 on the right side is vertically placed on the right pad 1214 and contacts the right baffle 1215, the right pad 1214 receives the partition-type radiator 16 on the right side, and the right baffle 1215 limits the bottom of the partition-type radiator 16 on the right side. The right pad 1215 is arranged obliquely to the bottom plate 12, so that the top of the partition-type radiator 16 on the right side is tilted to the right compared to the bottom, so that a larger volume of the partition-type radiator 16 can be used to improve the heat dissipation capacity;

[0041] The base 11 includes four vertically arranged support rods 111; the four support rods 111 are respectively located at the upper left, lower left, upper right and lower right of the base 11; the support rods 111 located at the upper left and lower left are fixed to the partition wall radiator 11 on the left; the support rods 111 located at the upper right and lower right are fixed to the partition wall radiator 16 on the right; when assembling the partition wall radiators 16 on the left and right sides of the heat dissipation device 1, the bottoms of the partition wall radiators 16 on the left and right sides are placed on the receiving member 121. If the partition wall radiators 16 are not fixed to the top plate 15, the bottom plate 12, the front plate 13 and the rear plate 14, the support rods 111 are fixed to the partition wall radiators 16, and the limiting effect of the receiving member 121 on the partition wall radiators 16 can be used to fix the partition wall radiators 16. The partition radiator 16 is supported, making it easier to assemble the partition radiators 16 on the left and right sides onto the heat dissipation device 1; when the partition radiator 16 has been fixedly assembled onto the heat dissipation device 1, the support rod 111 can support the middle part of the partition radiator 16 to prevent metal fatigue in the middle section of the partition radiator 16 and further damage the partition radiator 16; when it is necessary to remove the partition radiator 16 from the heat dissipation device 1, if the partition radiator 16 is removed from the top plate 15, the bottom plate 12, the front plate 13 and the rear plate 14, the partition radiator 16 can be fully stressed under the action of the receiving member 121 and the support rod 111, preventing the partition radiator 16 from falling from a high place after being removed from the top plate 15, the bottom plate 12, the front plate 13 and the rear plate 14.

[0042] In the modular data center dry cooler provided in Example 1 of the utility model, preferably, the bases 11 of all heat dissipation devices 1 can be spliced ​​and combined to facilitate the assembly and overall management of the dry cooler.
