Description

Technical Field

[0001] The utility model relates to the field of air duct design, in particular to a uniformly split air supply unit. Background Art

[0002] The computer room air conditioning system is mainly divided into chilled water air conditioning system, air-cooled direct evaporative air conditioning system, water-cooled direct evaporative air conditioning system, dual cold source air conditioning system, etc. Computer room air conditioning generally uses a fan installed on the roof to bring the outside air into the computer room, and cools down during the air replenishment process. After the air duct is installed, the top of the air inlet pipe generally needs to extend vertically to the roof. With the change of weather factors, the air inlet pipe is prone to leakage and water inflow, and the bottom of the air inlet pipe will extend into the computer room and use the diversion pipe for diversion. If there is leakage and water inflow, the water can easily spread to the entire computer room space through blowing, resulting in the computer room not meeting the requirements of constant temperature and humidity. The leak needs to be repaired in time, but if the leak is not serious, it is difficult to be directly discovered, and it takes a certain amount of time to find maintenance personnel. During this period of time to discover the leak and find maintenance personnel, it will bring certain economic losses. Therefore, it is necessary to set up a kind of air replenishment unit that can evenly divert and effectively waterproof, which is used to timely remind the leakage site to be repaired and provide buffer time for maintenance work.

[0028] like Figure 1-5 As shown, a uniformly split air supply unit of the utility model comprises an air supply pipe 1, wherein the air supply pipe 1 is vertically arranged, and an air supply diffuser 2 is connected to the bottom end of the air supply pipe 1;

[0029] A water baffle 3 is fixedly installed in the air supply pipe 1, and the water baffle 3 is tilted to the right. A plurality of air holes 4 arranged in a matrix are formed on the water baffle 3, and a plurality of water guide strips 5 arranged at equal intervals are formed on the bottom side of the water baffle 3. Both front and rear ends of the water guide strips 5 extend out of the air supply pipe 1, and the air holes 4 are located above the water guide strips 5.

[0030] The principle is: when rainwater leaks and flows into the air supply pipe 1, the rainwater will flow into the water guide strip 5 through the air vents 4 of the water baffle 3, and then be collected by the water guide strip 5 at the front and rear ends of the air supply pipe 1. The air flow will enter the machine room through the water guide strips 5 arranged at intervals, thereby achieving effective waterproofing. Whether the air supply pipe 1 is leaking can be directly judged by the dripping conditions at the front and rear ends of the water guide strip 5. When rainwater leaks, it can be effectively diverted. When a leak occurs, preparations can be made for maintenance work. During the preparation process, no rainwater will directly enter the machine room, thereby ensuring the effect of constant temperature and humidity in the machine room.

[0031] Furthermore: the upper edge of the right side of the water guide strip 5 is integrally formed on the bottom side of the water baffle 3, and the left edge of the water guide strip 5 and the bottom side of the water baffle 3 are spaced apart from each other; the cross-section of the water guide strip 5 is in a right-angle shape; the water baffle 3 is inclined to the right at an angle of 30 to 60°; a water flow channel can be formed to prevent rainwater from mixing into the air flow.

[0032] Furthermore: the front and rear sides of the air supply pipe 1 are both formed with a groove 6 inclined to the right, the front and rear ends of the water baffle 3 are respectively fixedly installed in the groove 6, and the front and rear ends of the water guide bar 5 are respectively extended out of the air supply pipe 1 through the groove 6; making the installation of the water baffle 3 more secure.

[0033] Furthermore: a flexible pipe 7 is connected between the air supply pipe 1 and the air supply diffuser 2, and the flexible pipe 7 is made of canvas or artificial leather; the setting of the flexible pipe 7 can avoid rigid contact assembly between the air supply pipe 1 and the air supply diffuser 2, and the flexible pipe 7 can provide a certain adjustment space during the assembly process, thereby facilitating the installation of the air supply diffuser 2 on the air supply pipe 1.

[0034] Furthermore: a first flange joint 8 is fixedly installed on the outer side of the bottom end of the air supply pipe 1, a second flange joint 9 is fixedly installed on the outer side of the top end of the air supply diffuser 2, and the flexible pipe 7 is fixedly installed between the first flange joint 8 and the second flange joint 9; making the assembly of the flexible pipe 7 more secure.

[0035] Further: both ends of the flexible pipe 7 are bent to form a folded edge 10, and a plurality of locking bolts 11 are fixedly installed on the first flange joint 8 and the second flange joint 9, and a U-shaped galvanized steel plate 12 is installed in the locking bolt 11. The locking bolt 11 passes through the U-shaped galvanized steel plate 12 and the folded edge 10 to lock the two ends of the flexible pipe 7 on the first flange joint 8 and the second flange joint 9 respectively; the outer edge of the folded edge 10 is gap-fitted in the U-shaped galvanized steel plate 12. After the locking bolt 11 is tightened, the U-shaped galvanized steel plate 12 can be pressed and bent, and then clamp the folded edge 10 of the flexible pipe 7, which can ensure the stable installation of the flexible pipe 7.

[0036] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
