Computer room air conditioning cabinet and its air duct structure

Abstract

The present invention provides an air duct structure, wherein incoming air flows from the air inlet of the air flow channel to the air outlet, is blocked by a heat exchanger and a baffle, passes through the heat exchanger to its outlet side, and a ventilation gap in the baffle connects the outlet side of the heat exchanger to the air outlet. This allows the incoming air that has passed through the heat exchanger to exit the air flow channel through the ventilation gap and then exit the air flow channel through the air outlet. The incoming air passes through the heat exchanger and flows out through the ventilation gap, increasing the flow rate of the incoming air as it passes through the ventilation gap. A water baffle extends from the ventilation gap and covers the water receiving tray. Water carried out of the water receiving tray by the incoming air is blocked below the water baffle, effectively preventing water in the water receiving tray from being carried away by the air flow and causing water splashing, thus preventing fan corrosion and preventing water droplets from being carried out of the air outlet and flowing into the computer room by the air flow, thereby ensuring the normal operation of the equipment in the computer room. The present invention also provides a computer room air conditioning cabinet.

Description

Technical Field

[0001] The present invention relates to the technical field of computer room air conditioners, and more particularly to a computer room air conditioner cabinet and an air duct structure thereof. Background Art

[0002] In a cabinet-type computer room data center, the relative humidity of the environment is closely related to the normal operation of the data center servers. Different components have their own specific tolerance values, and different components have different tolerance values ​​for electrostatic damage.

[0003] Existing computer room air conditioners draw air in through an air duct, which contains a water collection pan and evaporator. The air flows through the water collection pan and then the evaporator. Computer room air conditioners offer advantages such as small size, high humidification capacity per unit time, and low water quality requirements. However, these air conditioners are also required to be able to quickly adjust the temperature and humidity of the computer room environment. Furthermore, due to pressure differences before and after the evaporator or a malfunction in the water collection pan, water can easily fly out, impacting the safety of the cabinet-type computer room.

The incoming air flows out from the air inlet 1 of the air flow channel to the air outlet 2, is blocked by the heat exchanger 4 and the baffle 5, passes through the heat exchanger 4 to its air outlet side, and the ventilation gap 51 of the baffle 5 connects the air outlet side of the heat exchanger 4 to the air outlet, so that the incoming air passing through the heat exchanger 4 is discharged from the air flow channel through the ventilation gap 51 and then discharged from the air flow channel from the air outlet 2. The incoming air passes through the heat exchanger 4 and flows out through the ventilation gap 51, so that the flow rate of the incoming air increases when passing through the ventilation gap 51. A water baffle 52 is provided on the ventilation gap 51 to cover the water receiving pan 3, so that the water flow brought out of the water receiving pan 3 by the incoming air is blocked under the water baffle 52, effectively preventing the water in the water receiving pan 3 from being carried away by the air flow and causing water flying, preventing fan corrosion and preventing the air flow from bringing water droplets out of the air outlet 2 and flowing to the machine room, thereby ensuring the normal operation of the equipment in the machine room.

[0026] In a specific embodiment of the present invention, the heat exchanger 4 includes a first heat exchange portion 41 and a second heat exchange portion 42. One end of the first heat exchange portion 41 and one end of the second heat exchange portion 42 are arranged close to and connected to each other, while the other ends of the first heat exchange portion and the other ends of the second heat exchange portion are separated from each other and are both connected to the baffle 5. The ventilation gap 51 is located between the ends of the first heat exchange portion 41 and the second heat exchange portion 42 separated from each other. In other words, the heat exchanger 4 is composed of two parts. The first heat exchange portion 41 and the second heat exchange portion 42 are arranged in a V-shape, which increases the contact area of ​​the incoming air passing through the heat exchanger 4 within a limited space and improves the cooling capacity of the incoming air. The ends of the first heat exchange portion 41 and the second heat exchange portion 42 separated from each other are both connected to the baffle 5.

At the same time, the first heat exchange part 41 and the second heat exchange part 42 arranged in a V shape converge the airflow entering the air flow channel from the outside of the V shape to the inside of the V shape and then discharge it. The heat exchange area is large, and a heat exchanger 4 with a sufficiently large area can be fully arranged in a limited space to improve the heat exchange capacity.

[0027] In a specific embodiment of the present case, the first heat exchange portion 41 and the second heat exchange portion 42 are connected by a connecting plate 6, and a first air vent 61 is provided on the connecting plate 6 to connect the air inlet side and the air outlet side of the heat exchanger 4. The connecting plate 6 is connected to the first heat exchange portion 41 and the second heat exchange portion 42 on both sides of its width, supporting both at the same time, so that the support structure of the heat exchanger 4 in the air inlet direction is stable. At the same time, the heat exchanger is filled inside the air flow channel, and a first air vent 61 is provided to directly connect the air inlet side and the air outlet side of the heat exchanger 4, balancing the pressure difference on both sides of the heat exchanger 4, which can prevent the water level on the air outlet side of the water receiving tray 3 from being higher than the water level on the air inlet side due to excessive pressure difference between the air inlet side and the air outlet side of the heat exchanger 4, and prevent the water in the water receiving tray on the air outlet side from being carried away by the air flow and causing water splashing.

[0028] In a specific embodiment of this case, the air duct structure further includes two sidewall panels 7, a top panel (not shown), and a bottom panel 8, which enclose the airflow channel.

By providing the first wiring hole 53 and the second wiring hole 54, mounting brackets are provided at corresponding heights on the side wall panels 7 of the corresponding air duct, and high-voltage cables and low-voltage cables are respectively led out from the side wall panels 7 on both sides of the air duct, so that high-voltage cables and low-voltage cables are separated, electromagnetic interference is reduced, and the operating safety of electronic equipment is improved.

[0030] Furthermore, seals are provided between the baffle 5 and the two sidewalls 7, the top plate, and the bottom plate 8; and / or between the baffle 5 and the heat exchanger 4. The baffle 5, sidewalls 7, top plate, and bottom plate 8 are all sheet metal components, and the baffle 5 and heat exchanger 4 are also mechanically connected. Seals are provided between the connected sheet metal components. Preferably, the seals are made of sealing cotton to seal the installation gaps between the sheet metal components, preventing water from leaking out and improving safety. The sealing device can also be made of sealant or rubber.

[0031] In one specific embodiment of this case, the baffle 5 is provided with a second vent 57 that connects the air inlet and outlet sides of the heat exchanger 4. The installation of the baffle 5 affects the air inlet pressure within the airflow channel. To address the issue of water splashing caused by excessive air velocity discharged through the ventilation gap 51, the second vent 57 is configured to balance the pressure differential based on the wind speed. The baffle 5 is a sheet metal component, fixedly connected to the first heat exchange section 41 and the second heat exchange section 42 via two mounting portions. The second vent 57 comprises two sets of holes, one on each mounting portion, and is located within the bent structure of the sheet metal baffle 5.

[0032] In a specific embodiment of this case, a support frame 55 is provided on the ventilation opening 52, and both ends of the support frame 55 are connected to the baffle 5 on both sides of the ventilation opening 52. The baffle 5 includes at least two parts located on both sides of the ventilation opening 51. The support frame 55 is provided to connect the two parts of the baffle 5 on both sides of the ventilation opening 51, so that the baffle 5 is supported by the support frame 55 at the ventilation opening 52, further improving its structural stability.

[0033] A water pump fixing plate 9 is also provided on the water baffle 52, and a water level switch is also provided on the water pump fixing plate 6 to monitor the water level in the water tray 3. To ensure the water level safety in the water tray 3, a water pump fixing plate 9 is arranged on the water baffle 52, and a water level switch is provided on the water pump fixing plate 9. The water in the water tray 3 is discharged by the water pump, and the water level in the water tray is controlled by the water level switch to ensure the safety of the water level.
