Description
Technical Field
The invention relates to the technical field of servers and heat dissipation, in particular to a linear double-heat-source balanced heat dissipation mechanism of a server case. The invention also relates to a server chassis.
Background
With the development of the electronic technology in China, more and more electronic devices have been widely used.
Servers are important components in electronic devices, and are devices that provide computing services. Since the server needs to respond to and process the service request, the server generally has the capability of assuming and securing the service. The server is divided into a file server, a database server, an application server, a WEB server and the like according to different service types provided by the server. The main components of the server include a processor, a hard disk, a memory, a system bus, etc., and are similar to a general-purpose computer architecture, but the server is required to have high processing capability, stability, reliability, security, expandability, manageability, etc., because it needs to provide highly reliable services.
In the big data era, a large number of IT devices are centrally located in a data center. These data centers include various types of servers, storage, switches, and a large number of cabinets and other infrastructure. Each type of IT equipment is composed of various hardware boards, such as a computing module, a memory module, a chassis, a fan module, and the like.
Nowadays, servers and storage devices are more and more advanced, and the density of products is also more and more high, so that the heat dissipation performance of components needs to be ensured. In a server chassis, the installation positions of a plurality of components are often close and the heat generation amount is often large, that is, the front and rear heat source dual arrangement condition is obtained. For the heat source under the condition, at present, two radiators are often adopted to form a combination to radiate the heat of the front heat source and the rear heat source. However, in the actual heat dissipation process, it is found that the heat dissipation of the rear heat source is relatively poor, and the heat dissipation performance of the rear heat sink is insufficient due to the lower flow rate entering the rear heat sink because the front heat sink has higher impedance to the air flow. In the prior art, the impedance is generally reduced by reducing the number of the heat dissipation fins of the front row of heat dissipater, i.e. when the number of the heat dissipation fins is reduced, the distance between two adjacent heat dissipation fins is increased, so that the impedance is reduced, and the flow rate of cold air entering the rear row of heat dissipater is increased. However, although this method can increase the flow rate of the cooling air of the rear row radiator, the heat dissipation performance of the front row radiator is greatly reduced, the performance of the front row radiator is insufficient, and the heat dissipation performance of the front row radiator and the rear row radiator is still in an unbalanced state.
Therefore, how to improve the intake air flow rate of the rear row of radiators and balance the heat dissipation performance of the front row of radiators and the rear row of radiators on the basis of giving consideration to the heat dissipation performance of the front row of radiators and the rear row of radiators as much as possible is a technical problem to be solved urgently by technical personnel in the field.
Disclosure of Invention
The invention aims to provide a linear double-heat-source balanced heat dissipation mechanism of a server case, which can improve the intake flow of a rear row of radiators and balance the heat dissipation performance of the front row of radiators and the rear row of radiators on the basis of giving consideration to the heat dissipation performance of the front row of radiators and the rear row of radiators as much as possible. Another object of the present invention is to provide a server chassis.
In order to solve the technical problem, the invention provides a linear dual-heat-source balanced heat dissipation mechanism of a server case, which comprises a front-row heat sink for dissipating heat of a front-row heat source and a rear-row heat sink for dissipating heat of a rear-row heat source, wherein a plurality of first heat dissipation fins are uniformly arranged on the front-row heat sink along the wind direction, a plurality of second heat dissipation fins are uniformly arranged on the rear-row heat sink along the wind direction, the number of the first heat dissipation fins is equal to that of the second heat dissipation fins, and the surface area of the first heat dissipation fins in a preset proportion is smaller than that of each second heat dissipation fin.
Preferably, the first heat dissipation fins and the second heat dissipation fins are rectangular, and the length direction of the first heat dissipation fins and the length direction of the second heat dissipation fins are parallel to the wind direction.
Preferably, the width of the first radiator fins is smaller than the width of each of the second radiator fins by a preset ratio.
Preferably, 50% of the first radiator fins have a width smaller than that of each of the second radiator fins.
Preferably, 50% of the width of the first radiator fins is 1/2 of the width of each of the second radiator fins.
Preferably, the first heat dissipation fins and the remaining first heat dissipation fins in a preset proportion are distributed on the front row of heat sink in a mutually staggered manner.
The invention also provides a server case, which comprises a cabinet and a linear double-heat-source balanced heat dissipation mechanism arranged in the cabinet, wherein the linear double-heat-source balanced heat dissipation mechanism is specifically any one of the linear double-heat-source balanced heat dissipation mechanisms.
The invention provides a linear double-heat-source balanced heat dissipation mechanism of a server case, which mainly comprises a front row of radiators and a rear row of radiators. The front-row radiator is mainly used for radiating a front-row heat source in the linear double heat sources, and the rear-row radiator is mainly used for radiating a rear-row heat source in the linear double heat sources. The front row of radiators are uniformly provided with a plurality of first radiating fins along the flowing direction of cold air, and the rear row of radiators are uniformly provided with a plurality of second radiating fins along the flowing direction of cold air, wherein the first radiating fins and the second radiating fins are equal in number, and generally, the adjacent distances of the first radiating fins and the second radiating fins are also equal. What is important is that the first heat dissipating fins have a part of fins with preset proportion, and the surface area of the fins is smaller than that of each second heat dissipating fin. Therefore, the surface area of part of the first radiating fins is relatively reduced, so that the integral radiating performance of each first radiating fin is weakened to a certain extent, the blocking effect on inlet air cold air is reduced, larger flow of inlet air cold air can reach the rear-row radiator without blocking, and the radiating performance of the rear-row radiator is improved. It should be noted that only a part of the surface area of the first heat dissipation fins is reduced, and the proportion of the part of the fins is within a pre-designed proper range, so that the heat dissipation performance of the front row heat sink can be weakened to a certain extent, and the heat dissipation efficiency of the front row heat source is ensured. Compared with the mode that the flow of the rear row radiator is increased by reducing the number of the radiating fins and increasing the adjacent distance in the prior art, the invention only replaces the larger air inlet flow of the rear row radiator with the cost of weakening the radiating surface area of the front row radiator to a small extent, gives consideration to the comprehensive radiating performance of the front row radiator and the rear row radiator as much as possible, and balances the radiating efficiency of the front row radiator and the rear row radiator.

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 and fig. 2, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, and fig. 2 is a front view of fig. 1.
In a specific embodiment provided by the present invention, a linear dual-heat-source balanced heat dissipation mechanism of a server chassis mainly includes a front-row heat sink 1 and a rear-row heat sink 2.
The front-row radiator 1 is mainly used for radiating a front-row heat source in the linear double heat sources, and the rear-row radiator 2 is mainly used for radiating a rear-row heat source in the linear double heat sources. A plurality of first cooling fins 101 are uniformly arranged on the front row of heat sink 1 along the flow direction of the cool air, and a plurality of second cooling fins 201 are uniformly arranged on the rear row of heat sink 2 along the flow direction of the cool air, wherein the number of the first cooling fins 101 and the number of the second cooling fins 201 are equal, and the adjacent distances of the first cooling fins 101 and the second cooling fins 201 are generally equal.
It is important to note that there is a predetermined proportion of fins in the first radiator fins 101, and the surface area of the fins is smaller than that of the second radiator fins 201. Thus, the surface area of part of the first heat dissipation fins 101 is relatively reduced, so that the overall heat dissipation performance of each first heat dissipation fin 101 is weakened to a certain extent, but the blocking effect on the intake air cold air is reduced, the intake air cold air with larger flow rate can reach the rear heat radiator 2 without obstruction, and the heat dissipation performance of the rear heat radiator 2 is improved.
It should be noted that only a part of the surface area of the first heat dissipation fins 101 is reduced, and the proportion of the part of the fins is within a pre-designed proper range, so that the heat dissipation performance of the front row heat sink 1 can be weakened to some extent, and the heat dissipation efficiency of the front row heat source is ensured. Compared with the mode of increasing the flow of the rear-row radiator 2 by reducing the number of the radiating fins and increasing the adjacent distance in the prior art, the embodiment only replaces the larger air inlet flow of the rear-row radiator 2 with the cost of weakening the radiating surface area of the front-row radiator 1 by a small amount to improve, gives consideration to the comprehensive radiating performance of the front-row radiator 2 as much as possible, and balances the radiating efficiency of the front-row radiator 2.
In a preferred embodiment of the first radiator fins 101 and the second radiator fins 201, the first radiator fins 101 and the second radiator fins 201 are rectangular, such as rectangular or square, and the length directions of the first radiator fins 101 and the second radiator fins 201 are arranged parallel to the wind direction. Thus, when the cooling air flows, the cooling air can contact with the two side surfaces of the first radiator fins 101 and the second radiator fins 201, thereby absorbing heat.
Further, in order to conveniently reduce the surface area of the first radiator fins 101 by a predetermined ratio, the present embodiment reduces the width (or height) of the portion of the first radiator fins 101, the part of the first radiator fins 101 is made to be short, on one hand, the surface area is smoothly reduced, on the other hand, the air intake cooling air can directly pass through the top of the part of the first radiator fins 101, the impedance is reduced, and thus, the rear row heat sink 2, without hindrance, of course, the surface area of the first radiator fins 101 is reduced in a manner other than the width, when the first radiator fins 101 are rectangular, the length thereof can be reduced, and at this time, the impedance of the intake air and the cooling air is not changed, however, the contact time with the portion of the first radiator fins 101 is reduced, the amount of heat absorption is reduced, a portion of the heat absorption capacity is maintained, and the flow rate of the cool air entering the rear radiator 2 is increased.
Specifically, the width reduction degree of the first radiator fins 101 with the preset ratio may be 1/2, and of course, the left and right adjustment may be performed on the basis of the width reduction degree, and the higher the width reduction degree is, the larger the heat radiation performance of the front row radiator 1 is weakened, and vice versa.
Furthermore, the way of reducing the surface area of the first radiator fins 101 in a predetermined ratio may also vary according to the shape thereof. For example, if the first radiator fins 101 of the predetermined ratio are in a curved rectangular shape, i.e., the top side thereof is curved, such as a wavy line, the height can be reduced proportionally along the curve. In this way, by reducing the surface area of the first heat dissipating fins 101 in a curved manner, the turbulence level of the intake air-cooling air can be increased in the front row heat sink 1, and the heat dissipating performance of the front row heat sink 1 can be improved.
In order to achieve the comprehensive heat dissipation performance of the front row heat sink 1 and the rear row heat sink 2, in the present embodiment, 50% of the first heat dissipation fins 101 have a width smaller than that of the second heat dissipation fins 201, and the 50% shorter first heat dissipation fins 101 and the other 50% higher first heat dissipation fins 101 may be distributed on the front row heat sink 1 in a mutually staggered manner, so that the heat dissipation performance uniformity of the front row heat sink 1 can be improved. Of course, the distribution ratio of the shorter first radiator fins 101 to the taller radiator fins can be adjusted according to the actual heating condition of the linear dual heat sources, and the total adjustment criterion is to balance the heat dissipation performance of the front and rear radiators.
The embodiment further provides a server chassis, which mainly includes a cabinet and a linear dual-heat-source balanced heat dissipation mechanism disposed in the cabinet, where the linear dual-heat-source balanced heat dissipation mechanism is the same as the above-mentioned related content, and is 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. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
