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 schematic overall structure diagram of an embodiment of the present invention.
In an embodiment of the present invention, the wind guiding and heat dissipating structure with high wind speed and low power consumption mainly includes a wind guiding cover 1, an air inlet 101, an air outlet 102 and a heat dissipating fan 2.
The wind scooper 1 is laid in the box of the server case and covered on the surface of each heating component on the server motherboard, on one hand, the wind scooper protects each heating component, and on the other hand, outside cold air is supplied to circulate inside to dissipate heat of the heating component.
The air inlet 101 is arranged on the front end face of the air guide cover 1 and is mainly used for introducing outside cold air. The air outlet 102 is formed in the rear end face of the air guiding cover 1 and is mainly used for guiding the heat-exchanged outside cold air to the outside again. Importantly, the sectional area of the air outlet 102 is smaller than that of the air inlet 101, and a plurality of cooling fans 2 are arranged at the air outlet 102 and used for pumping out air inside the air guiding cover 1.
Thus, under the condition that the sectional area of the air inlet 101 is not changed (compared with the prior art), the flowing air speed is increased due to the fact that the sectional area of the air outlet 102 is reduced, the speed of taking heat of the heat generating components out of the external cold air is increased, and the heat exchange efficiency of the heat generating components is improved. Meanwhile, the sectional area of the air outlet 102 is reduced, and the number of the cooling fans 2 is correspondingly reduced, so that the power consumption is reduced, and the space occupation is reduced.
In summary, the high-wind-speed low-power-consumption wind-guiding heat-dissipating structure provided by the embodiment can improve the air flow rate in the wind-guiding cover 1, enhance the heat exchange performance, improve the heat-dissipating efficiency, and reduce the power consumption and the space occupation.
In a preferred embodiment of the wind scooper 1, the wind scooper 1 is detachably laid on the surface of the server motherboard, and the cover body of the wind scooper 1 covers the installation area of each heat generating component. With this arrangement, since the heat generating component can be thermally plugged or unplugged, the position (and the size and other parameters) of the heat generating component can be changed by the removal and reinstallation of the wind scooper 1. Specifically, the cover body of the wind scooper 1 may be connected to the server motherboard by fasteners such as bolts and rivets, or may be connected by an adhesive.
Meanwhile, the specific shape of the wind scooper 1 may be the same as that of the prior art, for example, it may be rectangular or elliptical. In the box body, the installation direction of the wind scooper 1 can conform to the airflow flowing direction, namely the length direction of the wind scooper is parallel to the airflow flowing direction, so that the air circulation is facilitated. In addition, the wind scooper 1 may be made of a transparent material, such as transparent plastic, so as to facilitate observation of the operation of the internal heat generating components.
Furthermore, an air inlet 101 formed at the front end of the air guide cover 1 can face the box body air inlet 101 of the server case and is opposite to the box body air inlet 101. Similarly, the air outlet 102 formed at the rear end of the air guiding cover 1 can face the box air outlet 102 of the server chassis and is opposite to the box air outlet 102. So set up, can reduce the useless flow path of outside cold air in the inside of box, improve the velocity of flow of outside cold air in the box inside to a certain extent.
In addition, in order to gradually increase the flow speed of the external cold air inside the wind scooper 1, in this embodiment, the sectional area of the wind scooper 1 gradually decreases from the front end face to the rear end face thereof, that is, the sectional area at the air inlet 101 of the front end face is the largest, and the sectional area at the air outlet 102 of the rear end face is the smallest, and the two gradually decrease according to a certain preset step value. With such an arrangement, the overall shape of the cover body of the wind scooper 1 can be conical.
In another preferred embodiment of the wind scooper 1, two sectional walls 103 are connected between the hood body of the wind scooper 1 and the outlet 102, the sectional walls 103 are inclined, and a chamfer effect is formed on the rear end face of the wind scooper 1, so that a sudden change effect is formed on the sectional area of the wind scooper 1, and the flow velocity of the outside cold air suddenly increases when the outside cold air flows to the outlet 102. With such an arrangement, the rear end face of the wind scooper 1 can be trapezoidal in shape.
As shown in fig. 2, fig. 2 is a specific structural schematic diagram of the heat dissipation fan 2 shown in fig. 1.
In a preferred embodiment of the heat dissipation fans 2, in order to facilitate the assembling and disassembling operations of the heat dissipation fans 2, in the present embodiment, each heat dissipation fan 2 is detachably disposed at the air outlet 102 of the air guiding cover 1. Specifically, in this embodiment, a plurality of clamping grooves are formed in the inside of the air outlet 102, and clamping plates are arranged on the outer walls of the cooling fans 2. The clamping plate is mainly used for being matched and clamped with the corresponding clamping groove, so that stable dismounting and mounting of each cooling fan 2 at the air outlet 102 are achieved through clamping matching or unlocking between the clamping plate and the corresponding clamping groove. Here, preferably, 2 heat dissipation fans 2 may be simultaneously disposed at the air outlet 102, and each heat dissipation fan 2 may specifically form a mortise and tenon joint structure with the side wall of the air outlet 102 through a buckle.
Further, in this embodiment, a temperature sensor is further added in each cooling fan 2 for detecting the temperature at the air inlet 102, and a temperature display screen 3 is further disposed on the cooling fan 2. The temperature display screen 3 is in signal connection with the temperature sensor, can receive real-time detection data of the temperature sensor and display the real-time detection data so that a worker can conveniently view the data. Specifically, the temperature display screen 3 is disposed on the top surface of the heat dissipation fan 2, and an observation hole 104 is formed on the cover body of the wind scooper 1. The observation hole 104 is specifically formed in a region corresponding to the installation position of each cooling fan 2, so that the temperature display screen 3 on the cooling fan 2 at the air outlet 102 is exposed, and the observation and reading by the staff are facilitated.
In addition, each cooling fan 2 can also be directly connected with a corresponding socket on the server mainboard through a USB data line, so that the unified power supply of the mainboard is realized, and the wiring design and the mainboard arrangement are simplified.
This embodiment also provides a server chassis, mainly includes the box and sets up the high wind speed low-power consumption wind-guiding heat radiation structure in the box, and wherein, this high wind speed low-power consumption wind-guiding heat radiation structure's specific content is the same with above-mentioned relevant content, and it is no longer repeated here.
