Description

TECHNICAL FIELD

[0001] The utility model relates to energy storage technical field especially relates to a novel ventilation and heat dissipation air duct for liquid cooling equipment. BACKGROUND

[0002] In today's era of rapid development of science and technology, various electronic devices have been widely used in many fields, such as server liquid cooling cabinet of data center, equipment cabinet of liquid cooling communication base station, liquid cooling electrical control cabinet in industrial automation and liquid cooling energy storage cabinet, etc. With the continuous improvement of electronic device performance, the integration of internal electronic components is getting higher and higher, and the power density continues to increase, and the heat generated during operation also increases sharply.

[0003] These liquid cooling equipment needs to be communicated with the external environment of the cabinet and needs to be heat exchanged, and when heat exchanged with the outside world, air cooling equipment is usually used, and then the sealing fit between the air duct and the heat dissipation window is needed, if the sealing performance is poor, the hot air that needs to be discharged outside the cabinet will return to the cabinet again, and then be sucked into other equipment, causing hot air backflow and secondary heating. This will greatly affect the working efficiency of the equipment, and even damage the electronic devices.

[0004] The current design of air duct faces the following problems:

[0005] 1. The current designed air duct needs to be close to the heat dissipation window, but the heat dissipation window is installed on the cabinet door, and its position and size are limited by the size, appearance and protection level requirements of the cabinet door; The air inlet and air outlet of the air duct are also limited by the space of the cabinet, and usually cannot be directly connected to the input and output, but only the shape of the air duct can be shaped to avoid the limitation caused by the space, the shaped wall not only increases the design and processing difficulty, but also increases the air resistance; The shaped air duct is also difficult to fully utilize the effective ventilation area of the heat dissipation window;

[0006] 2. The most direct method for sealing detection is to close the cabinet door to observe whether the two are closely attached, and the air outlet of the air duct in the prior art is generally in the deep part of the cabinet, so this method is difficult to achieve;

[0007] 3. The above two problems will cause hot air backflow, that is, the heat dissipation fan will reabsorb the air heated after passing through the heating equipment and use it to cool down again, which will greatly reduce the heat dissipation efficiency, and in severe cases, it will damage the heating equipment.

The advantage of this design is that the equipment with large heat generation is concentrated in the same space, and the heat dissipation is more targeted.

[0012] Preferably, the plurality of heating elements are separated by a heat dissipation partition plate, because the heat dissipation of both is relatively large, the heat dissipation partition plate is used to separate them, so that they are in parallel position in the heat dissipation air duct, and the exhaust hot air does not affect each other.

[0013] Further, the plurality of heating elements are cooled by independent fans respectively.

[0014] Further, the ventilation duct is divided into a first ventilation duct and a second ventilation duct along the extension line of the heat dissipation partition plate, and the fans and the matching ventilation ducts are used to cool the two equipment with large heat generation, so that the hot air does not exchange between them.

[0015] Further based on the above-mentioned work and heat dissipation separation equipment designs the corresponding air duct structure, including cabinet, first cabinet door, second cabinet door, ventilation duct, fan, heat dissipation window and inner baffle, the first cabinet door has the air inlet, the second cabinet door has the heat dissipation window, the fan inhales cool wind through the air inlet when working, and hot air is discharged from the heat dissipation window, in order to prevent hot air backflow, the inner baffle is also increased, the inner baffle has a through hole for connecting the ventilation duct, and the hot air is discharged from the ventilation duct, and due to the blocking effect of the inner baffle, the hot air is not sucked back by the fan, and the effect of preventing hot air backflow is achieved.

[0016] There is a hollow interlayer between the inner baffle and the heat dissipation window, and the hot air passes through the hollow interlayer to reach the heat dissipation window, and the ventilation duct in the prior art needs to be closely attached to the heat dissipation window, and the sealing property needs to be ensured to reduce hot air backflow, and through the design of the inner baffle and the hollow interlayer, the position and size of the ventilation duct can be more free, and the ventilation duct only needs to be connected to the through hole on the inner baffle, and the position and size of the through hole are not limited, and the sealing requirement between the ventilation duct and the heat dissipation window is transferred to the inner baffle and the cabinet, and compared with the sealing between the ventilation duct and the heat dissipation window, the sealing between the inner baffle and the cabinet is better achieved.

[0017] Preferably, the inner baffle also has a sealing part for sealing between the inner baffle and the second cabinet door.

[0018] Preferably, the inner baffle has a plurality of through holes connected to different ventilation ducts, and since the other end of the ventilation duct is provided with a fan, the hot air cannot flow between the ventilation ducts, and the hot air discharged from the plurality of ventilation ducts can jointly use the hollow interlayer and then be discharged from the heat dissipation window. This heat dissipation mode can effectively utilize the space of the hollow interlayer.

[0019] Preferably, the inner baffle also has a detachable sealing window, when the internal device is damaged, the small sealing window can be directly disassembled for repair or replacement, and the inner baffle connected to the ventilation duct does not need to be disassembled as a whole, so that the later maintenance is facilitated.

[0020] Preferably, the heat dissipation window is a louver structure, which can prevent accidental liquid splashing and unnecessary damage.

[0021] Preferably, the side of the heat dissipation window close to the inner baffle has a detachable dust screen.

[0022] The advantages of the utility model lie in:

[0023] 1. The air duct structure does not need to design special-shaped ventilation ducts, and does not need to closely attach the ventilation ducts to the heat dissipation window, so that production and manufacturing are simpler and more convenient; since the ventilation ducts used in the air duct structure do not need to change direction, the wind resistance caused by collision with the pipe wall is greatly reduced, and hot air backflow is further prevented.

[0024] 2. The advantage is that there is a hollow interlayer between the inner partition and the heat dissipation window, hot air passes through the hollow interlayer to reach the heat dissipation window, and the ventilation pipe in the prior art needs to be closely attached to the heat dissipation window and needs to ensure sealing to reduce hot air backflow, and after many operation experiments, it is found that even if the sealing is strengthened, the heat dissipation effect is poor, but through the design of the inner partition and the hollow interlayer, the position and size of the ventilation pipe can be more free, and the ventilation pipe only needs to be connected to the through hole on the inner partition in a straight line, and the position and size of the through hole can also be set according to the position of the ventilation pipe, and many actual operation experiments are also carried out, and it is found that the new air duct can greatly optimize the heat dissipation performance of the equipment.
