Combined type evaporative cooling unit

Abstract

The invention provides a combined type evaporative cooling unit. The unit comprises a shell, a direct evaporative cooling module and pre-cooling modules; the direct evaporative cooling module comprises a coiler heat exchanger and a first filler and is arranged inside the shell, the first filler is arranged below the coiler heat exchanger, and the coiler heat exchanger is sequentially provided with a first water distribution device and a first draught fan from bottom to top; the pre-cooling modules are arranged on two opposite sides of the shell and located below the first filler, one side of each pre-cooling module is provided with a communication opening communicated with the direct evaporative cooling module, and therefore air pre-cooled by the pre-cooling modules can flow into the direct evaporative cooling module; each pre-cooling module is formed by a vertical heat exchanger and a second filler; each pre-cooling module is sequentially provided with a second water distribution device and a second draught fan from bottom to top, and sliding devices capable of enabling the pre-cooling modules to slide are installed below the pre-cooling modules; and a ventilation opening is further formed in the lateral wall of the shell. By means of the sliding devices, the using manner of the unit is varied, the adaptability is good, and the practical performance is higher.

[0002] Dry air energy is a kind of clean renewable energy. In the case of increasingly depleted energy and increasingly harsh environment, it has been paid more and more attention, especially in Northwest my country where dry air energy is relatively abundant. However, the single use of dry air energy In addition, evaporative cooling technology also has the advantages of energy saving and environmental protection. Therefore, in recent years, many scholars have proposed to combine evaporative cooling technology with dry air energy, and this scheme has also been obtained. widely used

[0003] However, in practical applications, evaporative cooling technology itself also has many defects. For example, if direct evaporative cooling technology or indirect evaporative cooling technology is used alone, the unit will be limited by regional adjustment or insufficient cooling capacity; Under normal circumstances, the structure of the unit is relatively large and occupies a large area; moreover, in most cases, the use mode of an evaporative cooling unit is relatively single or the structure does not change, and the cooling capacity of the unit will be too much, resulting in a waste of energy
