Description

Technical Field

[0001] The utility model belongs to the field of servers, in particular to a server fan module. Background Art

[0002] With the advancement of science and technology and the development of high-tech industries, the performance of electronic devices is also improving. However, as the performance of electronic devices improves, the heat generated by them is also increasing, which in turn causes the overall temperature of the electronic devices to rise. When the temperature of an electronic device is too high, it is easy to reduce the operating efficiency of the electronic device or cause abnormal operation, or even cause a malfunction. In order to solve the high temperature problem, a heat dissipation device is often set up to reduce the temperature of the electronic device. Taking a server as an example, a fan module is generally installed in the server for heat dissipation. The fan module includes a fan compartment and a fan body installed in the fan compartment.

[0003] The Chinese patent publication "CN115390638A, installation module, fan module and server" includes: a module body; a rotating member, the rotating member is rotatably connected to one side of the module body, and the connection between the rotating member and the module body is the rotation center; the rotating member has a first edge, when the rotating member rotates, the first edge always contacts the installation object and changes the distance from the installation object to the rotation center, the installation object of this structure is fixed, the first edge always contacts the installation object, when the rotating member rotates, the distance between the installation object and the rotation center changes all the time, so that the rotation center and the installation object are relatively displaced. The position of the rotation center and the module body is relatively fixed, so the rotation center drives the module body and the installation object to be displaced. Finally, the purpose of separating the installation module from the installation object in a simple way is achieved.

[0004] However, although the rotating parts of the above structure can easily separate the module body and the installation object, when the temperature inside the server rises, a high-speed fan is required to dissipate heat. The higher the fan speed, the greater the high-frequency vibration transmitted. The high-frequency vibration of the fan is transmitted to the chassis, causing the chassis to vibrate and generate noise. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figure 1-7 ;

[0029] A server fan module is applied to a chassis 1. A module housing 2 is detachably installed on both sides of the chassis 1 through a locking assembly. A plurality of fan groups 3 for installing fans 4 are installed in the module housing 2. The utility model has three fan groups 3 installed in the module housing 2. Each fan group 3 can install two fans 4. The two fans 4 are installed in an upper and lower manner. The fan group 3 includes a front and rear fixed plate 31, and a side plate 32 respectively connected to the two sides of the fixed plate 31. The two fixed plates 31 are evenly arranged with heat dissipation holes corresponding to the positions of the fans 4. Through holes are respectively provided on the front and rear sides of the four corners of the fans 4. The inner sides of the two fixed plates 31 are provided with a plurality of latches 33 that can be inserted into the through holes. The latches 33 are covered with a plastic sleeve 34 The plastic sleeve 34 is made of soft plastic material. The plastic sleeve 34 can also be replaced with a rubber sleeve. The plastic sleeve 34 is in close contact with the inner wall of the through hole in multiple directions, which can prevent the fan 4 from vibrating and causing the fan 4 to deviate. It is also convenient for the disassembly and assembly of the fan 4. The soft characteristics of the plastic sleeve 34 can alleviate the vibration generated by the rotation of the fan 4 and reduce noise. A number of fixing members 25 are provided along the length direction of the module housing 2. The fixing member 25 is provided with a through hole, and a plastic nail 27 is inserted into the through hole. One end of the nail cap of the plastic nail 27 abuts against the lower end surface of the fixing member 25, and the other end abuts against the bottom upper end surface of the module housing 2. The soft characteristics of the plastic nail 27 can alleviate the vibration of the fan 4 transmitted to the chassis 1, further reducing noise.

[0030] During installation, first put the plastic sleeve 34 on the pin 33 on the fixing plate 31, then align the through hole 41 of the fan 4 with the pin 33 of one of the fixing plates 31 and insert it, then align the other fixing plate 31 with the through hole 41 on the other side of the fan 4 and insert it, and then respectively snap the two side panels 32 onto the two sides of the two fixing plates 31 to complete the installation of the fan group 3. After the fan group 3 is installed, put it into the module housing 2 and lock it with screws, then put it into the chassis 1, and lock the module housing 2 and the chassis 1 with the locking assembly.

[0031] Furthermore, buckles 321 are correspondingly provided on both sides of the two side panels 32, and holes 311 for snapping into the buckles 321 are provided on both sides of the two fixing plates 31. When installing the fixing plates 31 and the side panels 32, first connect the two fixing plates 31 with the fan 4, and then align the buckles 321 of the side panels 32 with the holes 311 on the fixing plates 31 and snap them in, and the installation of the fan group 3 is completed. When disassembling the fan group 3, the fan group 3 can be disassembled by simply pulling out the fixing plates 31, which facilitates the disassembly and assembly of the fan group 3.

[0032] In the utility model, the lock assembly includes a fixed column 11 arranged on the inner side of the chassis 1, and a rotating member 5 rotatably connected to the module housing 2. The connection between the rotating member 5 and the module housing 2 is a rotation center 51. The rotating member 5 is provided with an arc-shaped notch 52 for preventing the rotating member 5 from excessive rotation. The arc-shaped notch 52 is provided with an upper arc surface 521. When the rotating member 5 rotates upward, the upper arc surface 521 always contacts the fixed column 11 and changes the distance from the fixed column 11 to the rotation center 51. Since the fixed column 11 is fixedly installed on the chassis 1, the change in the distance from the fixed column 11 to the rotation center 51 is caused by the rotation center 51. Movement, the position of the rotation center 51 and the module body is relatively fixed, so that the rotation center 51 drives the module shell 2 to move. When the rotating member 5 rotates upward, the rotation center 51 will gradually move away from the fixed column 11. The fixed column 11 always provides an upward thrust to the rotating member 5, causing the module shell 2 and the chassis 1 to be displaced. The separation operation of the module shell 2 and the chassis 1 is achieved by controlling the relative displacement direction of the fixed column 11 and the rotation center 51. Therefore, it is only necessary to simply rotate the rotating member 5 upward to cause the module shell 2 and the chassis 1 to be relatively displaced, thereby achieving the purpose of easy disassembly of the module shell 2 and the chassis 1.

[0033] Furthermore, the rotating member 5 also includes a lower arc surface 522. When the rotating member 5 rotates downward, the fixed member 25 can move along the lower arc surface 522 and change the distance from the fixed column 11 to the center of the rotating rod. In this embodiment, when the rotating member 5 rotates downward, the rotation center 51 will gradually approach the fixed column 11, and the fixed column 11 always provides a downward pressure to the rotating member 5, thereby achieving the purpose of firmly installing the module housing 2 and the chassis 1.

[0034] It should be noted that the upper arc surface 521 and the lower arc surface 522 are smooth, and when the rotating member 5 rotates at the same speed, the displacement speed of the module housing 2 will be relatively uniform.

[0035] In this embodiment, pulleys 13 with grooves are provided on both sides of the chassis 1, and guide grooves 24 are provided on both sides of the module housing 2. The grooves of the pulley 13 are respectively in contact with the side walls of the guide groove 24. The bottom of the guide groove 24 is provided with an opening for the pulley 13 to slide out. The pulley 13 enters the guide groove 24 from the opening at the bottom of the guide groove 24. The cooperation between the guide groove 24 and the pulley 13 plays a limiting role, which can ensure that the installation position of the module housing 2 is accurate. No correction is required during installation, which is convenient for installation.

[0036] In this embodiment, a card slot 1 21 and a card slot 2 22 are symmetrically provided on both sides of the module housing 2, and the card slot 1 21 and the card slot 2 22 are set at a certain angle. A card buckle 2 53 is provided on the rotating member 5, and the edge positions along the card buckle 2 53, the card slot 1 21 and the card slot 2 22 are chamfered to facilitate the card buckle 2 53 to be inserted into the card slot 1 21 or the card slot 2 22, or to facilitate the card buckle 2 53 to be separated from the card slot 1 21 or the card slot 2 22. When the rotating member 5 is rotated upward by a certain angle, the card buckle 2 53 falls into the card slot 1 21 to achieve a limiting effect. When the rotating member 5 is rotated downward by a certain angle, the card buckle 2 53 falls into the card slot 22. During installation, the card buckle 2 53 can make the installer feel that the module housing 2 has been installed in place.

[0037] In this embodiment, limit portions 23 are further provided on both sides of the module housing 2, and the rotating member 5 extends out of the limit portions 23, and the lower end surface of the rotating member 5 abuts against the top of the limit portions 23, limiting the rotating member 5 from rotating downward at an excessive angle.

[0038] In this embodiment, a plurality of side panels 32 are provided with a carrying portion 322 on the top thereof. The carrying portion 322 facilitates taking out the fan assembly 3 together with the module housing 2 , and also facilitates taking out a single fan assembly 3 .

[0039] Since the server generates a large amount of heat during operation, excessively high temperature will cause hardware performance to deteriorate and may even cause permanent damage. The utility model dissipates heat for the server by setting up 6 fan groups 3. However, if each fan 4 operates at a high speed for a long time, it will lead to higher power consumption. Therefore, a temperature sensor 12 is installed in the chassis 1. The temperature sensor 12 is used to monitor the internal temperature of the chassis 1. The temperature sensor 12 is electrically connected to the external control module, and the external control module is electrically connected to the fan 4. For example, the data storage module is first preset to a temperature of 30, 35 or 40 degrees Celsius. The data storage module transmits the preset temperature value to the comparison module. The microprocessor controls the temperature sensor 12 to collect the temperature in the chassis 1 every five minutes. At the fifth minute, the temperature sensor 12 transmits the temperature data in the chassis 1 to the microprocessor, and the microprocessor transmits the data to the comparison module. The comparison module compares the temperature data transmitted by the microprocessor with the temperature data preset in the data storage module. For comparison, if the temperature inside the chassis 1 is less than 30 degrees Celsius, the microprocessor will feed back data to the external control module, and the external control module will stop the operation of two fans 4 through the hole to reduce power consumption. After 5 minutes, the temperature sensor 12 will collect the temperature inside the chassis 1 again. If the temperature inside the chassis 1 is between 30 and 35 degrees Celsius, the comparison module will transmit the data to the microprocessor, and the external control module will ensure the heat dissipation of the chassis 1 by restoring the speed of some of the stopped fans 4. After 5 minutes, the temperature sensor 12 will collect the temperature inside the chassis 1 again. If the temperature is between 35 and 40 degrees Celsius, the external control module will control all fans 4 to restore normal speed to reduce the temperature inside the chassis 1. After 5 minutes, the temperature sensor 12 will collect the temperature inside the chassis 1 again. If the internal temperature of the chassis 1 is greater than 40 degrees Celsius, the external control module will increase the speed of all fans 4 to ensure the normal operation of the hardware in the chassis 1 and avoid overheating inside the chassis 1, which will cause the temperature of the hardware to be too high and reduce the performance of the equipment.
