Embodiment 1

[0040] The basic structure of cooling chamber in the present embodiment is described as follows:

[0041] According to an embodiment of the present invention, a cooling chamber is provided, such as Figure 5 to Figure 7As shown, the cooling chamber includes: a main body 10 , a wind speed sensor 20 and a cooling unit 30 . Wherein, a through hole 13 is provided on the main body 10, and the main body 10 has an accommodating space, and the accommodating space is provided with a cooling channel 11 and a storage space 12, and the storage space 12 can be used to place articles. The cooling passage 11 communicates with the outside of the main body 10 through the through hole 13, and the air outlet of the cooling unit 30 communicates with the cooling passage 11. The cooling unit 30 sends cold air into the cooling passage 11, and cools the storage space 12 through the cooling passage 11. In this embodiment, the cooling room is specifically a modular data center, and the storage space 1...

Embodiment 2

[0059] This embodiment provides a cooling chamber structure different from that of Embodiment 1, specifically as follows:

[0060] Such as Figure 8 As shown, according to yet another embodiment of the present invention, a cooling chamber is provided, which differs from the cooling chamber provided in Embodiment 1 above only in that in this embodiment, a plurality of through holes are arranged at intervals on the body 10 13. The cooling chamber includes a plurality of wind speed sensors 20, and a plurality of through holes 13 are provided in one-to-one correspondence with the plurality of wind speed sensors 20. The cooling channel 11 is detected by a plurality of wind speed sensors 20 to ensure that the overall pressure of the cooling channel 11 is greater than the external pressure of the main body 10, so that the wind speed at each through hole 13 reaches a preset value, thereby ensuring that the cooling channel 11 as a whole has a positive impact on the cabinet. 40 air vol...

Embodiment 3

[0062] According to Embodiment 3 of the present invention, a method for controlling the air volume of the cooling unit in the cooling chamber is also provided, such as Figure 9 to Figure 11 As shown, wherein, the cooling chamber is the cooling chamber provided in the foregoing embodiments, and the method includes:

[0063] Step S202, acquiring wind speed detection data at the through hole of the cooling chamber.

[0064] Specifically, the wind speed detection data at the through hole can be detected by the wind speed sensor in the cooling chamber. Wherein, the wind speed detection data may include airflow direction and airflow velocity.

[0065] Step S204, judging whether the wind speed detection data conforms to the wind speed preset data.

[0066] Among them, the wind speed detection data can reflect the static pressure state of the airflow outside the cooling channel and the body. When the static pressure of the cooling channel is greater than the static pressure outside...

Abstract

The invention discloses a cooling room and a cooler unit air volume control method of the cooling room. The cooling room comprises a cooling room body, an air velocity sensor and a cooler unit. A through hole is formed in the cooling room body. The cooling room body is internally provided with an accommodating space. The accommodating space is internally provided with a cooling channel and a storing space. The cooling channel communicates with the outside of the cooling room body by the through hole. The air velocity sensor is arranged at the through hole. The air outlet of the cooler unit communicates with the cooling channel. The cooler unit is used for supplying air to the cooling channel based on detection data of the air velocity sensor, and therefore the cooling channel can cool thestoring space. The technical problems of the poor synchronism between cooler unit air output and actual demand and poor draught fan rotating speed controlling stability are solved.

Description

technical field [0001] The invention relates to the technical field of server cabinets, in particular to a cooling room and a method for controlling the air volume of a cooling unit in the cooling room. Background technique [0002] Currently, existing modular data centers are equipped with cabinets, power distribution units, air conditioners, water distribution units, and the like. Wherein, the server is arranged in the cabinet, and the temperature of the cabinet is cooled by the air conditioner, so that the server can run in a good environment. When cooling the cabinets in the existing modular data center, the temperature of the cabinets is detected in the following two ways. [0003] The first type, such as figure 1 As shown, the temperature sensor is used to detect the temperature of the cabinet. Specifically, a supply air temperature sensor 5 and a return air temperature sensor 6 are respectively installed at the air supply and return air of each air conditioner, so ...
