With the development of new infrastructure such as cloud computing and big data, the requirement on data computing speed is higher and higher, the computing speed and the computation load of a processor are also higher and higher, so that the power consumption of CPU components is increased dramatically and the temperature spec is also reduced, especially the power consumption of the CPU is increased greatly by 80% every year, so that the heat dissipation of electronic devices in a server becomes a problem which is troublesome at present, the requirement on the power consumption of a system cooling fan in the current society is higher and higher, and the requirement on a machine room PUE is reduced continuously.

At present, in order to effectively solve the problem of over-high temperature of electronic components of a server, the air volume of a server heat dissipation system is basically limited due to the limitation of the current fan technology without simply increasing the air volume of a fan.

In the prior art, part of technical schemes reasonably utilize the current air volume by installing the air guide cover in the server case, so that the maximum utilization rate is achieved, and the Spec of each device is met by more fully utilizing the limited air volume. In order to fully exert the performance of the existing fan and fully utilize the cold air flow, the conventional air guiding cover is generally provided with different holes or flow channels according to the configuration, position distribution and the like of different rear parts, so that the cold air flow is divided into a plurality of strands to respectively flow to each rear part for heat dissipation. However, the rear components configured on the servers with different specifications have different parameters such as types, numbers, positions, etc., for example, the distribution form of the rear components on the 1U server and the 2U server may be different, so that the wind scoops need to be manufactured according to the actual situation of the rear components of the servers with different specifications, and at least 3 wind scoops are generally required to be configured, which not only significantly increases the heat dissipation cost, but also causes much trouble for operations such as later installation and testing. In addition, although the air guiding cover divides the air flow, the cold air still transfers heat to the rear parts after passing through the main heating parts such as the CPU and the memory, so that the main rear parts such as the GPU are influenced by large temperature rise.

Therefore, how to reduce the influence of temperature rise on the rear component in the server as much as possible and achieve the universality of the wind scooper for servers of different specifications is a technical problem faced by those skilled in the art.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a perspective view of an overall structure of an embodiment of the present invention (arrows indicate a cold air intake direction).

In a specific embodiment provided by the invention, the general efficient wind scooper mainly comprises a cover body 2, a CPU cover frame 3, a memory cover frame 4, a diversion tail wing plate 31 and a diversion inclined plate 41.

The cover body 2 is a main structure of the wind scooper, generally in a frame shape, and is installed in the chassis 1 of the server, and is mainly used for guiding and shunting the inlet airflow (i.e., cold air) in the chassis 1.

The CPU cover frame 3 is one of the main components of the cover body 2, and is specifically covered on a CPU mounted on a motherboard, and is mainly used to form an independent cold air channel for the CPU, so that a part of cold air entering from the front end of the chassis 1 is branched and is dedicated to heat dissipation and cooling of the CPU.

The memory cover frame 4 is also one of the main body components of the cover body 2, is specifically connected to the two sides of the CPU cover frame 3, and is mainly used for covering memories (strips) which are installed on the motherboard and located on the two sides of the CPU to form separate cold air channels for each memory, so that a part of cold air flow entering from the front end of the case 1 is divided to be specially used for cooling the memories.

Importantly, the diversion tail wing plate 31 is arranged at the end position of the CPU cover frame 3 deviating from the cold air inlet direction, namely the rear end position of the CPU cover frame 3 (based on the air inlet direction of the case 1), and is mainly used for guiding the air flow flowing through the CPU cover frame 3 to the gaps of the rear parts arranged at the rear end of the case 1, so that after partial cold air flow flows through the CPU cover frame 3 and absorbs the heat of the CPU, most of the air flow can flow through the gaps between the rear parts, the air flow is prevented from directly passing through the rear parts, and the air flow absorbing the heat of the CPU is prevented from transmitting the heat to the rear parts.

The flow guide sloping plate 41 is arranged on the memory cover frame 4 and is mainly used for guiding cold air outside the memory area to the memory area, so that the flow of the cold air inside the memory cover frame 4 is increased.

Therefore, the general efficient wind scooper provided by the embodiment provides separate cold wind flow channels for the CPU and the memory on the motherboard through the CPU cover frame 3 and the memory cover frame 4, and the diversion tail wing plate 31 is used to enable the airflow absorbing the heat of the CPU to flow through the gap between the rear parts, so as to avoid the heat of the CPU from being transferred to the corresponding rear parts, and meanwhile, the diversion inclined plate 41 is used to increase the flow of the cold wind flowing through the memory, thereby reducing the influence of the temperature rise of the rear parts corresponding to the memory.

Compared with the prior art, the position relation of the CPU and the memory components on the server mainboard with any specification is fixed, so that the position relation of the CPU cover frame 3 and the memory cover frame 4 on the cover body 2 is relatively fixed, position adjustment is not needed according to the rear component, and further, the universal efficient wind scooper provided by the embodiment can be suitable for servers with different specifications, and universality is realized.

It should be noted that, because one CPU usually corresponds to two sets of memories on two sides, one CPU cover frame 3 and two memory cover frames 4 on two sides thereof form one set, and on a server with a higher specification, more than one CPU, such as 2 or more, is usually installed, and at this time, a plurality of sets of CPU cover frames 3 and memory cover frames 4 can be simultaneously disposed on the cover body 2. Further, since a plurality of CPUs are generally arranged in parallel, the CPU lid frame 3 and the memory lid frame 4 of each group may be integrally connected.

As shown in fig. 2 and 3, fig. 2 is a detailed structural schematic diagram of the cover 2, and fig. 3 is a partial perspective view of fig. 2.

In an alternative embodiment of the air guide tail flap 31, the air guide tail flap 31 is connected to the CPU housing 3 in a rotatable manner. Specifically, the flow guiding tail wing plate 31 is generally rectangular, and the front end side edge of the flow guiding tail wing plate 31 is rotatably connected with the rear end of the CPU cover frame 3, so that the flow guiding tail wing plate 31 can perform a turning motion relative to the rear end of the CPU cover frame 3, and the direction of the air flow flowing out of the rear end of the CPU cover frame 3, i.e., the inclination angle or the turning angle of the flow guiding tail wing plate 31, is adjusted by turning the flow guiding tail wing plate 31. With the arrangement, when the position of the gap between the rear parts corresponding to the CPU cover frame 3 changes, the airflow flowing out of the rear end of the CPU cover frame 3 can be ensured to flow through the gap between the rear parts by adjusting the overturning angle of the flow guide tail wing plate 31.

In some embodiments, the diversion flap 31 may be rotatably connected to the left side of the rear end of the CPU housing frame 3, for example, by a hinge, a rotating shaft, a pin, or the like, and may further be locked by a locking member such as a latch to lock the turning angle of the diversion flap 31.

Similarly, the diversion tail wing plate 31 can also be rotatably connected with the right side of the rear end part of the CPU cover frame 3.

Of course, if necessary, the flow guide tail wing plate 31 may be connected to two pieces of the CPU cover frame 3 at the same time and disposed on the left side and the right side of the rear end portion of the CPU cover frame 3, respectively.

In addition, in order to prevent the air flow from escaping after flowing out from the rear end of the CPU cover frame 3, in the present embodiment, the rear end side of the guide vane 31 is in contact with the gap side wall of the corresponding rear component. With the arrangement, after the airflow is guided by the guide tail wing plate 31, the airflow enters the gap between the adjacent rear parts along the guide tail wing plate 31, and the airflow is prevented from escaping in the midway.

In an alternative embodiment of the air guide sloping plate 41, the air guide sloping plate 41 is specifically disposed at the top position of the memory cover frame 4 and mainly used for guiding the cold air flowing in the region above the memory downward to the memory region. Because the height of the memory cover frame 4 is usually larger than the height of the memory, a vertical space is formed between the top surface of the memory cover frame 4 and the top end surface of the memory, and cold air flows through the space corresponding to the space. By such arrangement, part of the cold air flow which is positioned in the memory cover frame 4 but does not flow through the memory can be effectively utilized, and finally, the effect that almost all the cold air flow which passes through the memory cover frame 4 must pass through the memory is achieved.

In some embodiments, the height of the top end of the diversion inclined plate 41 is the same as the height of the top surface of the CPU cover frame 3, so that the diversion inclined plate 41 can be conveniently and integrally connected with the CPU cover frame 3, thereby facilitating early processing and manufacturing and saving cost.

In some embodiments, the bottom end height of the diversion inclined plate 41 is the same as the top end height of the memory, so that the bottom end surface of the diversion inclined plate 41 can just abut against the top end surface of the memory, and the cold air flow guided by the diversion inclined plate 41 gradually moves downwards along the surface of the diversion inclined plate 41 until reaching the memory area. In general, the inclination angle (or slope) of the swash plate 41 is usually 30 ° to 60 °.

In some embodiments, in order to accurately prevent the airflow flowing through the memory from flowing out of the memory housing 4 and reaching the rear component, the present embodiment considers that the installation position of the rear component such as the GPU may be relatively higher at the rear end of the chassis 1, and for this reason, the height of the bottom end of the diversion inclined plate 41 is designed to be the same as the lowest installation height of the corresponding rear component, or the same as the height of the bottom surface of the rear component. With this arrangement, when the airflow flowing through the memory cover frame 4 flows to the rear end of the chassis 1, the airflow can pass through the bottom gap of the rear component such as the GPU while avoiding the installation area of the rear component such as the GPU, thereby preventing the heat carried by the airflow from being transferred to the rear component.

Further, the bottom end of the diversion inclined plate 41 specifically abuts against the end position of the top of the memory facing the cold air intake direction, that is, the bottom end face of the diversion inclined plate 41 abuts against the front end position of the top end face of the memory. With the arrangement, when the cold air flow flows downwards along the diversion inclined plate 41, the cold air flow enters the gap between the adjacent memories from the front end space of the memories, and the cold air flow is ensured to pass through the whole memory.

Furthermore, in order to prevent the cool air from escaping to other areas when passing through the internal storage, a flow guiding cover plate 42 is connected to the bottom end (or the rear end) of the flow guiding sloping plate 41. Specifically, the flow guiding cover plate 42 covers the top end surface of the memory to seal the top of the memory, thereby preventing the cold air flow from escaping when flowing in the gap of the memory.

In addition, the flow guiding sloping plate 41 can not only incline from top to bottom, but also incline from left to right or from right to left, so that the cold air flow outside the two side areas of the memory can be guided to the memory area, and the purpose of increasing the cold air flow of the memory cover frame 4 can be achieved.

In order to facilitate the assembly, disassembly and position adjustment of the cover body 2 in the case 1, in this embodiment, mounting insertion boards 21 are disposed on both sides of the cover body 2, and the mounting insertion boards 21 are mainly used for being inserted into the case 1 and forming a detachable connection, such as a plug-in connection, with the case 1. Specifically, the installation inserting plate 21 can be in a U-shaped clamping piece shape and can be inserted into the side walls of the two sides of the case 1 from the vertical direction, so that the side walls of the case 1 are clamped tightly, and meanwhile, the elastic deformation of the installation inserting plate 21 can be utilized to improve the clamping force on the side walls of the case 1, so that stable connection is realized. When the mounting position of the cover body 2 needs to be adjusted, the mounting inserting plate 21 is pulled off to be separated from the clamping of the side wall of the case 1, and then the cover body 2 is slid along the length direction of the case 1. When the cover body 2 needs to be detached, the mounting insertion plate 21 is pulled off to be separated from the clamping of the side wall of the case 1, and then the cover body 2 is pulled out upwards.

The embodiment further provides a server, which mainly includes a chassis 1 and a general efficient wind scooper disposed in the chassis 1, wherein specific contents of the general efficient wind scooper are the same as those described above, and are not described herein again.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
