Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a water-saving indirect evaporative cooling equipment. Background Art

[0002] Indirect evaporative cooling means that the indoor air is in a closed loop, and the indoor air is cooled without direct contact with external water and air. Indirect evaporative cooling prevents external moisture and pollutants from entering the data center, and is an important evolution direction for modular, low-energy cooling solutions for large data centers.

[0003] The external air used to cool the indoor air is cooled by spraying and exchanges heat with the indoor air, thereby cooling the indoor air. The sprayed external air carries a large amount of water vapor with it when discharged, which not only causes steam pollution, but also takes away a large amount of water, which is contrary to the concept of energy conservation and environmental protection. Utility Model Content

[0007] Furthermore, the spray head is arranged in the water condensation shell, and the spray head is arranged between the fixing plate and the bottom of the water condensation shell.

[0008] Furthermore, the reduction assembly also includes a first gear fixedly disposed at the output end of the motor, the first gear is meshedly connected with a second gear, the second gear is fixedly disposed on a connecting rod, and the diameter of the first gear is smaller than that of the second gear.

[0009] Furthermore, the lifting components and the deceleration components are the same in number and are multiple.

[0010] Furthermore, the motor is a dual-axis motor, and another output shaft of the dual-axis motor is fixedly connected to a fan blade.

[0011] In the above technical solution, the utility model provides a water-saving indirect evaporative cooling device with the following beneficial effects:

[0012] 1. Through the condensation mechanism, when the outside air in the fresh air duct cools down the indoor hot air in the hot air duct, the outside air moves into the condensation shell, passes through the through holes and sponge of the fixed plate, and the sponge absorbs the water vapor in the outside air to reduce the water vapor in the exhaust air.

[0013] 2. Through the extrusion mechanism, the motor drives the connecting rod to rotate through the reduction assembly. The rotation of the connecting rod cooperates with the limit groove and the limit rod. At the same time, due to the sliding limit of the pressure plate and the condensate shell, the lifting cylinder is driven to move up and down. The up and down movement of the lifting cylinder drives the up and down movement of the pressure plate. The up and down movement of the pressure plate can squeeze the sponge on the fixed plate, thereby squeezing out the water adsorbed in the sponge and discharging it into the water accumulation tray through the through hole.

The limit rod 431 can be symmetrically arranged to improve the stability of the limit rod 431 when sliding in the limit groove 432; the inlet of each of the fresh air ducts 1 is connected to the air intake pipe, and the air intake pipe is connected to the water accumulation tray, which is convenient for the rapid cooling of the external air and the discharge of the water squeezed out of the sponge into the water accumulation tray; the sponge can be a bamboo charcoal sponge, an activated carbon sponge, or the like that has a good adsorption capacity for water vapor.

[0025] Through the provided condensation mechanism, when the external air in the fresh air duct 1 cools down the indoor hot air in the hot air duct 2, the external air moves into the condensation shell 31, passes through the through hole 33 of the fixed plate 32 and the sponge, and the sponge absorbs the water vapor in the external air to reduce the water vapor in the discharged air; through the provided extrusion mechanism, the motor 41 drives the connecting rod 420 to rotate through the reduction assembly, and the connecting rod 420 rotates through the cooperation of the limit groove 432 and the limit rod 431. At the same time, due to the sliding limit of the pressure plate 44 and the condensation shell 31, the lifting cylinder 430 is driven to move up and down. The up and down movement of the lifting cylinder 430 drives the up and down movement of the pressure plate 44. The up and down movement of the pressure plate 44 can squeeze the sponge on the fixed plate 32, thereby squeezing out the water adsorbed in the sponge and discharging it into the water accumulation tray through the through hole 33.

[0028] Furthermore, the lifting components and the deceleration components are equal in number and are multiple, so as to improve the stability of the pressing plate 44 when it moves.

[0029] Furthermore, the motor 41 is a dual-shaft motor 41, and the other output shaft of the dual-shaft motor 41 is fixedly connected with a fan blade 6. The fan blade 6 is used to accelerate the discharge of the external air after the water vapor is removed.

[0030] Working principle: When the external air in the fresh air duct 1 cools down the indoor hot air in the hot air duct 2, the external air moves into the condensation shell 31, passes through the through hole 33 of the fixed plate 32 and the sponge, and the sponge absorbs the water vapor in the external air to reduce the water vapor in the exhaust air; the motor 41 rotates, and drives the connecting rod 420 to rotate through the engagement of the first gear 421 and the second gear 422, and the connecting rod 420 rotates through the limit groove 432 and the limit rod 431. At the same time, due to the sliding limit of the pressure plate 44 and the condensation shell 31, the lifting cylinder 430 is driven to move up and down. The up and down movement of the lifting cylinder 430 drives the up and down movement of the pressure plate 44.
