Description

[Technical field]

[0001] The present disclosure relates to a server cooling device. [Background technology]

[0002] Conventionally, a server cooling device is used to cool the server as a measure against heat generated by the server. Patent Document 1 discloses an air conditioning system that cools the server room by blowing air cooled by a cooler into a cold air supply path provided under the floor or on the ceiling. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-148333 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology of Patent Document 1, the air is uniformly heated while passing through the cold air supply passage, so the cooling efficiency decreases as it approaches the end of the passage, and as a result, the server cannot be cooled efficiently.

[0005] The present disclosure has been made in consideration of the above, and has an object to provide a server cooling device that can efficiently cool a server. [Means for solving the problem]

[0006] The server cooling device of the present disclosure is a server cooling device that is disposed in the space under the floor of a server, extends approximately parallel to the ground, and includes a heat exchanger that separates a lower space from an upper space, and a blower that exhausts air that has flowed in from the lower space out of the upper space. Effect of the Invention

[0007] According to the present disclosure, it is possible to realize a server cooling device that can efficiently cool a server. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a schematic configuration diagram of the server cooling device. [Diagram 3] FIG. 3 is a schematic configuration diagram of a server cooling device according to the second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A server cooling device according to an embodiment of the present disclosure will be described with reference to the drawings. Note that components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] (Embodiment 1) [Server Cooling System] Fig. 1 is a schematic configuration diagram of a server cooling system including a server cooling device according to embodiment 1. As shown in Fig. 1, the server cooling system 1 includes a server room 2 that houses a plurality of servers, a server cooling device 3 that is disposed in an underfloor space of the server room 2 and cools a refrigerant such as oil for cooling the servers housed in the server room 2, and a concrete foundation 4 made of concrete or the like having a large heat capacity.

[0011] The server room 2 includes a pump that circulates a coolant that cools the servers, and an oil tank that stores the coolant. The server room 2 accommodates the servers therein and cools the accommodated servers with the coolant.

[0012] The server cooling device 3 may also function as an oil pan or soundproofing equipment as stipulated in the Fire Service Act.

[0013] In order to perform efficient heat exchange in the server cooling device 3, the concrete foundation 4 is preferably constructed with a large thermal capacity, such as the ground or a concrete foundation.

[0014] [Server cooling device] Fig. 2 is a schematic diagram of a server cooling device. Fig. 2(a) corresponds to a view seen from an arrow A in Fig. 1, Fig. 2(b) corresponds to a view seen from an arrow B in Fig. 1, Fig. 2(c) corresponds to a view seen from an arrow C in Fig. 1, and Fig. 2(d) corresponds to a view seen from an arrow D in Fig. 1, respectively.

[0015] As shown in FIG. 2, the server cooling device 3 includes an air vent 11, partitions 12 and 13, a radiator 14, an exhaust port 15, a sub-tank 21, a pump accessory 22, and a maintenance and inspection port 23.

[0016] The ventilation opening 11 introduces outside air into the interior of the server cooling device 3 .

[0017] The partition wall portion 12 forms an air flow path so that the outside air taken in from the vent hole 11 flows along the concrete foundation 4 side.

[0018] The partition portion 13 forms an air flow path so that the air guided by the partition portion 12 flows toward the arranged radiator 14 .

[0019] The radiator 14 is an integrated heat exchanger and fan, and may be, for example, an automobile part that cools engine coolant, transmission oil, etc. in a vehicle.

[0020] The heat exchanger has a dense network of piping and cools a refrigerant, such as oil, circulating inside the piping. The heat exchanger extends substantially parallel to the ground and separates the lower space from the upper space.

[0021] The blower blows air into the piping of the heat exchanger to increase the efficiency of heat exchange by the heat exchanger. The blower also exhausts the air that has flowed in from the lower space through the upper space. The blower may be integrated with the heat exchanger, or may be provided separately from the heat exchanger. In that case, the blower only needs to be disposed between the ventilation opening 11 and the exhaust opening 15 so that the air that has flowed in from the ventilation opening 11 is exhausted from the exhaust opening 15.

[0022] The exhaust port 15 exhausts the air inside the server cooling device 3 to the outside.

[0023] The sub-tank 21, together with the oil tank in the server room 2, stores the refrigerant.

[0024] The pump accessory 22 assists in driving the pump in the server room 2 .

[0025] The maintenance and inspection hatch 23 is used for maintenance and inspection of various equipment located below the maintenance and inspection hatch 23.

[0026] According to the server cooling device 3 described above, the radiator 14 is extended substantially parallel to the ground, and the lower space of the radiator 14 serves as the intake side for cool air. As a result, high temperature air and low temperature air can be separated above and below the radiator 14, enabling efficient heat exchange.

[0027] Furthermore, according to the server cooling device 3, the partition wall 12 allows the outside air taken in through the vent 11 to be cooled by the concrete foundation 4 before passing through the radiator 14, thereby enabling efficient heat exchange.

[0028] (Embodiment 2) Fig. 3 is a schematic configuration diagram of a server cooling device according to embodiment 2. As in Fig. 2, Fig. 3(a) corresponds to a view seen from an arrow A in Fig. 1, Fig. 3(b) corresponds to a view seen from an arrow B in Fig. 1, Fig. 3(c) corresponds to a view seen from an arrow C in Fig. 1, and Fig. 3(d) corresponds to a view seen from an arrow D in Fig. 1, respectively.

[0029] 3, the server cooling device 103 includes an air vent 111, partitions 112, 113, and 117, a radiator 114, an exhaust port 115, cooling fins 116, a sub-tank 121, and a pump accessory 122. Note that a description of the same configuration as in the first embodiment will be omitted.

[0030] The cooling fins 116 are disposed in the air flow path formed by the partition wall 112, and efficiently cool the air through the concrete foundation, which has a large thermal capacity.

[0031] The partition wall 117 efficiently guides the air that has passed through the radiator 114 to the exhaust port 115 .

[0032] The pump accessory 122 may be located on the radiator 114 side of the space partitioned by the partition portion 113 .

[0033] According to the server cooling device 103 described above, the radiator 114 is extended substantially parallel to the ground, and the lower space of the radiator 114 serves as the intake side for cool air. As a result, high temperature air and low temperature air can be separated above and below the radiator 114, and efficient heat exchange can be achieved.

[0034] Furthermore, according to server cooling device 103, partition 112 allows outside air taken in through vent 111 to be cooled by the concrete foundation before passing through radiator 114, thereby enabling efficient heat exchange.

[0035] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
