Indirect low-evaporation cooling device

Abstract

The invention discloses an indirect low-evaporation cooling device comprising a refrigeration unit, a cooling box body and a cooling water tank. The cooling box body internally comprises a cooling water main pipe connected to a cooling water supply pipe and a plurality of modular headers distributed in an array, each rows of modular headers are connected in series, each first-end modular header isconnected to the cooling water main pipe through a branch pipe, and each tail-end modular header communicates to the cooling water tank through a water outlet pipe; and a cooling fan is arranged at the top of the cooling box body, an air inlet is formed in the side face of the cooling box body, the refrigeration unit comprises a compressor, an evaporator and a condenser, the evaporator and the condenser are connected to the compressor, the evaporator is placed in the cooling water tank, and the condenser is placed at an air outlet of the cooling fan. The indirect low-evaporation cooling device can greatly reduce the water loss caused by evaporation of the cooling water, saves water resources, greatly reduces the generation amount of white fog, and meanwhile can increase the temperature drop range.

Description

technical field [0001] The invention relates to a cooling water cooling device, in particular to an indirect low evaporation cooling device. Background technique [0002] At present, the known cooling water cooling method adopts direct spray cooling, the cooling effect is good, and the water temperature after cooling can be close to the wet bulb temperature of the outdoor air, but its disadvantages are obvious, the water consumption is large, and the heat is taken away by water evaporation. When the room temperature is low, it is easy to generate a large amount of white mist, which will cause great pollution to the environment, reduce the permeability of the surrounding air, and have a great impact on the production environment, and the return water temperature of the cooling water cannot be adjusted. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an indirect low-evaporative cooling device, which c...
