Embodiment approach 1

[0047] use Figure 1 ~ Figure 3 , the configuration of the rack for electronic equipment according to Embodiment 1 of the present invention will be described. figure 1 It is a structural diagram showing the structure of the rack for electronic equipment according to Embodiment 1 of the present invention, showing the overall view including the rack for electronic equipment from the front, and showing the exhaust side of the rack for electronic equipment on which one server is mounted. Doors are provided with built-in radiators. figure 2 It is a sectional view explaining the temperature distribution of the server exhaust when the server is mounted on the rack for electronic equipment according to Embodiment 1 of the present invention, image 3It is a cross-sectional view illustrating a mounting position of a temperature sensor when a server is mounted on the rack for electronic equipment according to Embodiment 1 of the present invention.

Embodiment approach 2

[0058] Embodiment 2 is based on Embodiment 1, and the shape of the heat pipe is made into a flat plate.

[0059] Below, according to Figure 4 , the configuration of the rack for electronic equipment according to Embodiment 2 of the present invention will be described. Figure 4 In the configuration diagram showing the configuration of the rack for electronic equipment according to Embodiment 2 of the present invention, only the rear door portion is shown.

[0060] like Figure 4 As shown, the shape of the heat pipe of the unit 501 is flat instead of a general circular shape, and copper or aluminum fins 802 are connected to the flat heat pipe 801 by soldering or the like.

[0061] Thereby, the effect of alleviating heat concentration can be further enhanced.

[0062] Next, according to Figure 5 , the relationship between the ratio of the heat pipes to the flow path area and the air volume in the rack for electronic equipment according to Embodiment 2 of the present invent...

Embodiment approach 3

[0066] Embodiment 3 is based on Embodiment 2, and the unit 501 which consists of finned heat pipes is installed in the front door side rather than the rear door side of the electronic equipment rack.

[0067] Below, according to Figure 6 , the configuration of the rack for electronic equipment according to Embodiment 3 of the present invention will be described. Figure 6 It is a structural diagram showing the structure of the rack for electronic equipment according to Embodiment 3 of the present invention, but only the front door portion is shown.

[0068] exist Figure 6 In this example, a plurality of servers 301 are mounted in a rack 101 for electronic equipment, and a unit 501 composed of flat heat pipes 1102 connected with fins 1103 is disposed on the front door 1101 side. In addition, multiple fans are provided on the rear door side.

[0069] In this way, in this embodiment, since the flat heat pipe 1102 is arranged on the front door 1101 side, the temperature of th...

Abstract

The invention relates to an electronic apparatus rack and a data center and provides an electronic apparatus rack which can prevent the degradation of cooling performance due to local heat concentration on the exhaust side of the server. The electronic apparatus rack (101) having electronic apparatuses mounted thereon, consists of a radiator (200) incorporated in the rear door (102) of the electronic apparatus rack (101), plural fans installed on the exhaust side of the radiator (200), and plural heat pipes (602) installed on the intake side of the radiator (200).

Description

technical field [0001] The present invention relates to a rack for electronic equipment, and more particularly to improvement of cooling performance when the exhaust temperature distribution of servers installed in the rack for electronic equipment varies greatly. Background technique [0002] As semiconductor devices such as central processing units (CPUs) mounted in electronic equipment such as personal computers and servers are miniaturized and highly integrated, the amount of heat generated is increasing. Accordingly, there is an increasing need to increase the capacity of racks on which servers are mounted and the capacity of air conditioners in data centers that manage the racks together. [0003] In order to adapt to such a trend, in recent years, a method such as that described in Japanese Patent Application Laid-Open No. 2010-041007 (Patent Document 1) has been proposed. In the door of the exhaust part, the refrigerant flows through the radiator, and then the heat ...
