Embodiment 2

[0121] In the second embodiment 2 of the present invention, the server rack 200 consists of Figure 10 exhibit.

[0122] Figure 10 A front view of the server rack 200 showing the outline of the air cooler 240 is shown.

[0123] The server rack 200 changes the air cooler 140 of the server rack 100 in the first embodiment, the path of the refrigerant circuit 141 and the direction of the air cooling louvers 144, many elements are common to the server rack 100 of the first embodiment, Therefore, the common items are omitted, and the last two digits after the number 200 are the common symbols.

[0124] Figure 10 As shown, the refrigerant circuit 241 of the air cooler 240 of the server rack 200 is branched from the refrigerant inlet 242 to the outlet 243 and extends toward the pillar installation direction (upper direction) and merges.

[0125] The air cooling louvers 244 are arranged in the horizontal direction.

[0126] The air humidity in the server room is not high, and t...

Embodiment 3

[0128] In the third embodiment of the present invention, the overall SC of the server cooling device consists of Figure 11 exhibit.

[0129] Figure 11 It is an overall conceptual diagram of the server cooling system SC.

[0130] In the server cooling device SC of the third embodiment, the heat exchanger of the server cooling device SC in the first embodiment is changed, and many elements are in common with the first embodiment, so the description of the common items is omitted.

[0131] Figure 11 As shown, the server cooling device SC consists of cascade condenser CC, low-pressure liquid receiver LLR, compressor CP, evaporative condenser EC, high-pressure liquid receiver HLR, expansion valve EX, liquid pump PP1, liquid pump PP2, carbon dioxide Liquid reservoir GLR, evaporator EV composition.

[0132] The cascade condenser CC cools and liquefies the gas refrigerant.

[0133] The liquid pump PP1 transports the liquid refrigerant from the low-pressure liquid receiver LLR ...

Abstract

Provided is a server rack that, with a compact structure, efficiently cools a server and safely prevents damage to the server by a liquid coolant. The server rack (100) cools a server with cold air, and comprises: a shelf board on which the server is placed; a plurality of columns that directly or indirectly support the shelf board; an air current generating fan that generates an air current between multiple shelf boards placed at an interval in the extension direction of the columns and in a direction along the shelf boards; and an air cooler that is placed integrally with the server rack on the upstream side of the air current, and that cools air with a coolant. The air cooler has a coolant path for circulating the coolant, and a liquefied gas (RF), which serves as the coolant, flows in from a coolant inlet positioned on one end of the coolant path, is sent through the coolant path while evaporating, and is discharged from a coolant outlet positioned on the other end of the coolant path.

Description

technical field [0001] The invention belongs to the technical field of server cooling, and specifically relates to a server rack and a server cooling device, which are suitable for a server room with a large amount of heat generation like a data center, which needs to maintain a certain suitable room temperature, and provides a place for the server. rack while providing cooling. Background technique [0002] The applicant had previously applied for a patent on a server rack (Patent Document 1), JP-A-2014-89695 (especially the attached Figure 5 ), the above-mentioned server rack patent that has been applied for does not cool the server by the server rack itself, but recovers the hot air discharged from the server rack, and provides it to the server after cooling, which requires a large amount of circulating air, so a large fan is required , air ducts and other large equipment, and the temperature is prone to unevenness in the server rack area. [0003] In order to make the ...
