Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 It is a structural schematic diagram of a heat dissipation device provided by an embodiment of the present invention. see figure 1 , the cooling device includes: a control module 101 , a main fan group 102 , at least one backup fan 103 and a transmission device 104 .

[0037] The main fan group 102 includes a plurality of fans placed side by side. The fans rotate normally to drive the air flow in the area in front of the fans, so that the heat in the area in front is taken away by the air flow to dissipate heat in the area in front. However, during the working process, one or more fans may fail. At this time, the failed fan will not be able to dissipate heat to the front area, which will affect the overall heat dissip...

Abstract

The invention discloses a heat dissipation device, a server and a standby fan control method, and belongs to the field of electronic devices. The heat dissipation device comprises a main fan set, at least one standby fan, a conveying device and a control module. The main fan set comprises a plurality of fans arranged side by side, and the number of at least one standby fan is smaller than that ofthe fans of the main fan set. The conveying device is adjacent to the main fan set and is approximately parallel to the fan arrangement direction of the main fan set; the control module is connected with each fan in the main fan set, each standby fan and the conveying device, and the control module is used for detecting the position of the failure fan in the main fan set and controlling the conveying device to move the standby fan to the standby position corresponding to the position of the failure fan, so that the standby fan works at the standby position. By arranging a small number of standby fans, on the premise that the heat dissipation effect is guaranteed, the cost of the standby fans is reduced, power consumption generated when the fans work is reduced, and noise is lowered.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a cooling device, a server and a control method for a standby fan. Background technique [0002] With the development of electronic technology and the continuous expansion of server functions, people have higher and higher requirements for server stability. However, in many cases, the server will generate a large amount of heat due to long hours of work, resulting in a sharp rise in temperature, which in turn will cause the server to fail to work normally. In order to avoid the above situation, a cooling device is usually installed in the server, and the server is radiated through the cooling device to ensure temperature stability. [0003] The cooling device includes two fan groups, each fan group includes a plurality of fans placed side by side, and the number of fans in the two fan groups is equal, and one of the fan groups is located in front of the other fan group, so that...
