Description

server system

The present invention relates to a servo system, and more particularly to a servo system with cooling compensation.

Compared with personal computers (such as desktop computers, notebook computers, etc.), server computers have more powerful computing power, and because server computers are mostly used in commercial, financial, and even meteorological, military, and other fields, Its reliability and stability requirements are higher than personal computers. Therefore, the server computer is more rigid than the personal computer in the design of hardware and software. .

In general, in addition to installing a heat sink to remove heat from the server, the general server has a set of protection mechanisms to prevent component damage in the server. When the heat dissipation efficiency of the heat sink is insufficient and the operating temperature in the server is higher than a preset threshold, the servo system will be automatically shut down unexpectedly, thereby preventing the electronic components in the server from being too high in operating temperature. Damaged. However, since the purpose of setting up the server is mostly for commercial and financial purposes, once the server is unexpectedly shut down, the impact will be quite serious. Therefore, how to improve the heat dissipation efficiency of the server will be the goal that the research and development personnel are pursuing.

The present invention provides a servo system for improving heat dissipation efficiency of a server.

Each server The rack module comprises a cabinet, a plurality of servo hosts and a fan member. The cabinet has a first side and a second side opposite to each other. The first side is closer to the wind side than the second side. The servo hosts are respectively detachably mounted in the cabinet, and each of the servo hosts includes a temperature monitoring member. The fan member is mounted on the first side of the cabinet. The fan member contains a plurality of fans. These fans are electrically connected to the controller. The first side of one of the two cabinets abuts against the second side of the other of the two cabinets. When the two fan members are operated, an air flow is formed in the two cabinets side by side. The air flow flows from the air inlet side of the servo system to the air outlet side, and these servo hosts are located in the flow path of the air flow. When at least one fan of the two fan components is damaged, the controller is configured to increase the rotational speed of the fan member near the air outlet side to increase the heat dissipation efficiency of the servo system.

According to the servo system disclosed in the above invention, each server rack module has a fan member, and the two server rack modules are arranged side by side such that one of the two fan members is close to the air inlet side of the servo system, and the two fans One of the components is close to the wind side of the servo system. When any one of the two fan components is damaged, the controller increases the rotational speed of the fan member near the air outlet side to increase the heat dissipation efficiency of the servo system.

The features, implementations, and utilities of the present invention are described in detail below with reference to the drawings.

1 to 4, FIG. 1 is a perspective view of a servo system according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the first embodiment, and FIG. 3 is a servo system of FIG. Schematic diagram of electrical relationship, Fig. 4 is a side view of Fig. 1.

The servo system 10 of this embodiment has an opposite air inlet side 20 and an air outlet side. 30. The servo system 10 includes two server rack modules 40 (Server Rack Module) and a controller 50. The two server rack modules 40 are side by side with the server rack module 40. For convenience of description, the number of the server rack modules 40 in this embodiment is exemplified by two, but not limited thereto. In other embodiments, the number of the server rack modules 40 may be three or more. .

Each server rack module 40 includes a cabinet 100, a plurality of servo hosts 200, and a fan member 300. The cabinet 100 has a first side 110 and a second side 120 opposite to each other. The first side 110 of the cabinet 100 is closer to the wind side 20 than the second side 120. In addition, the cabinet 100 has a plurality of storage areas 130 (as shown in FIG. 4). These storage areas 130 are each maintained at a different height from the bottom of the cabinet 100. These servo hosts 200 are detachably mounted in respective storage areas 130 in the cabinet 100. The fan member 300 is mounted on the first side 110 of the cabinet 100, and the fan member 300 includes a plurality of fans 310. These fans 310 are located in each storage area 130. The first side 110 of one of the two cabinets 100 abuts against the second side 120 of the other of the two cabinets 100. In detail, the first side 110 of the cabinet 100 remote from the wind side 20 abuts against the second side 120 of the cabinet 100 adjacent the wind side 20 such that the two server rack modules 40 are side by side. Moreover, the storage areas 130 of the same height of the two server rack modules 40 communicate with each other.

Please refer to Figures 2 and 4. As can be seen from the above, the servo system 10 of the present embodiment is divided into a plurality of storage areas 130 of different heights. However, for the heat dissipation effect, the effects of the fans 310 in the storage area 130 of the same height on the servo host 200 in the storage area 130 of the same height are most obvious. The influence of each fan 310 of the storage area 130 of the different height on the above-mentioned servo host 200 gradually decreases as the distance approaches. Therefore, the storage area 130 of one of the heights will be first described below. When the fans 310 of the storage area 130 of the same height are operated, the fans 310 in the storage area 130 of the same height form an air flow in the two cabinets 100 arranged side by side. The airflow flows from the air inlet side 20 of the servo system 10 to the air outlet side 30 (in the direction indicated by arrow a), and these servo hosts 200 are located in the flow path of the airflow, thereby carrying away the heat generated by the servo host 200.

However, when at least one fan 310 is damaged in the storage area 130 of the same height, the number of fans 310 in the storage area 130 at the same height is reduced, so that the whole of the fans 310 in the storage area 130 will be made. The heat dissipation efficiency is reduced. If the overall heat dissipation efficiency continues to decrease, the temperature of the servo host 200 in the storage area 130 may continue to rise or even crash, affecting the user who is using the servo system. Therefore, when at least one fan 310 is damaged in the storage area 130 of the same height, the fan 310 returns a signal that the fan speed is zero or a fan is abnormal to the controller 50. Then, the controller 50 starts to increase the rotational speed of each fan 310 in the storage area 130 of the same height that is closer to the air outlet side 30 to improve the heat dissipation efficiency of the servo system 10. The method for detecting the damage of the fan can be, for example, transmitted through the tachometer. When the tachometer detects that the speed of a certain fan 310 is abnormally reduced or reset to zero, a signal indicating that the fan speed is zero or the fan is abnormal is transmitted to the controller 50. In addition, some types of fans can also directly provide a speed signal or a fan abnormal signal for use by the controller 50.

In this embodiment and other embodiments, when the heat dissipation efficiency of the servo system 10 cannot be effectively improved after the rotation speed of the fan 310 near the air outlet side 30 is increased, the controller 50 further increases the storage area 130 of the same height. The rotational speed of each fan 310 in the air inlet side 20 is increased to improve the heat dissipation efficiency of the servo system 10.

The above-mentioned first speed of each fan 310 close to the air outlet side 30 is increased, and then close The order in which the rotational speeds of the fans 310 on the air inlet side 20 are increased is not intended to limit the present invention. In other embodiments, the number of revolutions of the fans 310 near the wind inlet side 20 may be increased first, and the number of revolutions of the fans 310 near the wind outlet side 30 may be increased.

In addition, in this embodiment and other embodiments, when the heat dissipation efficiency of the servo system 10 cannot be effectively improved after the rotation speed of the fan 310 near the wind inlet side 30 is increased, the controller 50 further increases the height difference. The rotational speed of each fan 310 in the storage area 130 further increases the heat dissipation efficiency of the servo system 10. In detail, these servo hosts 200 each include at least one temperature monitoring component 210. These temperature monitoring components 210 are electrically connected to the controller 50, respectively. These temperature monitoring components 210 are used to monitor the temperature conditions of these servo hosts 200, respectively. When the temperature monitoring component 210 detects that the temperature of one of the servo hosts 200 is higher than a threshold, the corresponding temperature monitoring component 210 transmits the temperature abnormality signal of the servo host 200 to the controller 50, so that the controller 50 The rotational speeds of the fans 310 in the storage area 130 of different heights are further increased to improve the heat dissipation efficiency of the servo system 10. The above threshold value is a temperature value set according to a safe temperature range in which the electronic components in the servo host 200 can operate normally.

Please refer to Fig. 5. Fig. 5 is a schematic cross-sectional view taken along line 5-5 of Fig. 4. In the present embodiment, each servo host 200 of each server rack module 40 can be drawn away from the cabinet 100 in a first direction D1 away from the cabinet 100. The air flow extends along a first side 110 of the cabinet 100 toward a second direction D2 of the second side 120. The first direction D1 and the second direction D2 are substantially perpendicular to each other. Substantially perpendicular to each other means that the angle between the first direction D1 and the second direction D2 may be 90 degrees or approximately 90 degrees. In this way, when the server rack modules 40 are arranged side by side, the airflow can be driven from the servo. The air inlet side 20 of the service system 10 flows to the air outlet side 30, and the servo host 200 can also be detached from the cabinet 100 without hindrance.

In addition, in this embodiment and other embodiments, each server rack module 40 further includes a cooling member 400. The cooling member 400 is mounted on the first side 110 of the cabinet 100, and the fan member 300 is interposed between the cooling member 400 and the servo hosts 200. When the temperature monitoring component 210 senses that the temperature of one of the servo hosts 200 is higher than the threshold, the corresponding temperature monitoring component 210 transmits the temperature abnormality signal of the servo host 200 to the controller 50, so that the controller 50 further The cooling temperatures of the cooling members 400 of the same server rack module 40 are further lowered to lower the temperature of the airflow flowing into the cabinets 100.

In detail, each cooling member 400 includes a fluid driving device 410, a cooling coil 420, and a temperature regulator 430. There is a cooling fluid within the cooling coil 420 and the cooling coil 420 is in communication with the fluid drive 410. The fluid drive 410 is electrically coupled to the controller 50 and used to drive the flow of cooling fluid within the cooling coil 420. The temperature regulator 430 is electrically coupled to the controller 50 and is in thermal contact with the cooling coil 420.

In this embodiment and other embodiments, when the temperature monitoring component 210 detects that the temperature of one of the servo hosts 200 is higher than a threshold, the controller 50 is configured to enable the fluid driving device 410 of the same server rack module 40. Increasing the flow rate of the cooling fluid in the cooling coil 420 near the wind inlet side 20, or the controller 50 is configured to cause the temperature regulator 430 of the same server rack module 40 to be lowered to the cooling tray near the wind side 20. The temperature of the cooling fluid within the tube 420 increases the heat exchange efficiency between the cooling member 400 and the air.

It should be noted that when the fan component 300 generally introduces the air outside the cabinet 100 into the interior of the cabinet 100, the outside air will first exchange heat with the cooling member 400, so that the temperature of the airflow flowing into the cabinet 100 is lowered, thereby allowing the airflow. The heat exchange with the servo host 200 reduces the temperature of the servo host 200. However, in the present embodiment, since the controller 50 additionally increases the flow rate of the cooling fluid in the cooling member 400 or lowers the temperature of the cooling fluid in the cooling member 400, the airflow into the cabinet 100 can be more effectively reduced. The temperature, in turn, increases the heat exchange efficiency between the servo host 200 and the airflow.

According to the servo system disclosed in the above invention, each server rack module has a fan member, and the two server rack modules are arranged side by side such that one of the two fan members is close to the air inlet side of the servo system, and the two fans One of the components is close to the wind side of the servo system. When any one of the two fan components is damaged, the controller increases the rotational speed of the fan member near the air outlet side to increase the heat dissipation efficiency of the servo system.

In addition, each server rack module has a cooling member, and the two server rack modules are arranged side by side such that one of the two cooling members is close to the air inlet side of the servo system, and one of the two cooling members is close to the servo system. Wind side. When the temperature of the servo host between the two cooling members is higher than the critical value, the controller will lower the temperature of the cooling member close to the wind inlet side, so that the temperature of the airflow entering the cabinet is lowered, thereby increasing the airflow and the servo. Heat exchange efficiency between hosts.

While the present invention has been described above in its preferred embodiments, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of patent protection shall be subject to the definition of the scope of the patent application attached to this specification.
