Modular cross-flow closed cooling water tower

Abstract

The invention relates to a modular cross-flow closed cooling water tower, which comprises a shell, at least one cross-flow tube bank module alternatively arranged up and down on the edge of the inner side of the shell, a fan arranged above the shell, and a water sprinkling unit, wherein the fan is used for conducting the air flow through the cooling tower from the outside of the shell; the water sprinkling unit is used for sprinkling water from top to bottom to fillings and the cross-flow tube bank modules in a circulation mode. The modular cross-flow closed cooling water tower is characterized in that each cross-flow tube bank module consists of a plurality of cooling water pipes in a preset form. Moreover, the flow direction of the air flow flowing among the cross-flow tube bank modules and the feeding direction of the cooling water are in a state of approximately reversely flowing with a certain difference in temperature, so that the cooling tower can more effectively utilize sprinkling water and the air flow to perform the heat-exchange operation with the cooling water. The design of the modular tube bank can obtain convenient installation and maintenance and can reduce the equipment cost.

Description

technical field [0001] The present invention relates to a modularized cross-flow airtight cooling water tower, especially a modularized structure that uses unidirectionally arranged pipe rows to form a nearly countercurrent convection with the air flow, so as to utilize water spraying and replacement The air flow performs heat exchange work with the cooling water. Background technique [0002] The cooling water tower outside the traditional air conditioning unit is an open heat exchange structure, that is, the heat exchange operation in the cooling water tower, the cooled cooling water is directly in contact with the heated air, such an operation method will at least produce The disadvantages are: the scaling problem of the cooling water circulation pipeline, because the cooling water and the air are in exposed contact, so the particles floating in the air will be taken away by the cooling water, and circulate with the cooling water, plus the cooling water The problem of lo...

[0002] The cooling water tower outside the traditional air conditioning unit is an open heat exchange structure, that is, the heat exchange operation in the cooling water tower, the cooled cooling water is directly in contact with the heated air, such an operation method will at least produce The disadvantages are: the scaling problem of the cooling water circulation pipeline, because the cooling water and the air are in exposed contact, so the particles floating in the air will be taken away by the cooling water, and circulate with the cooling water, plus the cooling water The problem of loss of cooling water needs to be replenished, which can easily cause the accumulation of scaling factors in the cooling water pipeline. As a result, scaling and dirt accumulation will occur in the cooling water pipeline (especially in the condenser), directly causing Sustained reduction in heat exchange efficiency of chilled water units
