Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Along with the improvement of computer performance, the power density of the whole machine is higher and higher, the requirement on the heat dissipation capacity of the system is higher, for an air cooling heat dissipation system, a heat dissipation scheme mainly comprises a heat radiator design, a fan model selection, a ventilation hole design, an air duct design and the like, wherein the ventilation hole is very critical to improving the heat dissipation capacity of the system by combining with the air duct design, and the good ventilation hole and air duct design can effectively increase the system air volume and improve the heat dissipation efficiency.

At present, for the design of a plurality of cases, because the heat dissipation is carried out on the internal heating part, the fixed ventilation structures are designed on the front panel, the rear panel, the left side and the right side of the case generally. For some systems requiring more stringent heat dissipation inside, such as the internal heat dissipation unit, it is necessary to further increase ventilation holes on the rack top cover of the heat dissipation unit to increase the air intake for heat dissipation.

However, since the rack-up rate of the rack usually does not reach 100%, there is a free space inside the chassis, and outside cold air enters the inside of the chassis from the ventilation structure on the surface of the chassis and then enters the heat generating unit through the ventilation holes on the rack. When the density of the rack server is not high, and under the condition that a front baffle is additionally arranged in the space of the rack, the upper cover opening can cause hot air at the air outlet to flow back to the system through the upper cover opening due to negative pressure, internal circulation is easily generated in the case, so that the hot air is difficult to discharge, the heat dissipation is seriously influenced, and the heat dissipation effect is deteriorated on the contrary due to the increased upper cover opening.

In view of the above drawbacks, the present embodiment provides a design scheme of a heat dissipation structure, which avoids cooling air from circulating inside a chassis by changing an air guiding structure of an upper cover, thereby ensuring a heat dissipation effect. The concrete structure is as follows:

as shown in fig. 1 to 4, the present embodiment provides a rack heat dissipation structure, which includes a heat dissipation assembly 1 and an air guiding assembly 2, wherein a heat dissipation unit is disposed inside the heat dissipation assembly 1; a first air inlet 1a and a first air outlet 1b are respectively formed at two ends of the heat dissipation assembly 1, a vent 1c is formed at the top of the heat dissipation assembly 1, and the first air inlet 1a, the first air outlet 1b and the vent 1c are communicated with the inside and the outside of the heat dissipation assembly 1; an air guide channel is formed in the air guide assembly 2, the air guide channel is provided with a second air inlet 2a and a second air outlet 2b which are communicated with the outside, the second air inlet 2a and the first air inlet 1a face the same direction, and the second air outlet 2b is covered on the ventilation opening 1 c.
