Abstract

The invention discloses an energy-saving anti-freezing dry and wet type air cooler. The energy-saving anti-freezing dry and wet type air cooler comprises a spraying circulating water tank, an air inlet grate, a wet cooling section cooler, a spraying system, a dry cooling section cooler and a pneumatic system which are sequentially arranged from bottom to top. The spraying circulating water tank is provided with a water replenishing opening and is connected with the spraying system through a spraying pump and a water tube. The energy-saving anti-freezing dry and wet type air cooler is characterized in that the dry cooling section cooler consists of an inclined base tube and fins arranged on the inclined base tube. Compared with the original evaporative air cooler, the energy-saving anti-freezing dry and wet type air cooler has the advantages that the water is saved by 30%, the electricity is saved by 50%, the cooling performance is improved twice at least, water in the tube is drained easily, and an anti-freezing effect is high.

Description

technical field [0001] The invention relates to cooling technology, in particular to a cooling device for a wet and dry air cooler. Background technique [0002] In thermal power generation industry, coal chemical industry, new energy industry, forging, casting, heat treatment, steel, central air conditioning, photovoltaic, paper making, cosmetics, food and other industries, there are many process media that need to be cooled. The fins of the original wet and dry air cooler are dense flat fins with a fin spacing of 2.5mm and a large drag coefficient, which makes the fan use a lot of power and consume a lot of electricity. And because the distance between the sheets is too small, it is very easy to be blocked by debris and scale, and finally cannot be cooled. This is the biggest disadvantage of the original wet and dry air cooler. The lower section of the original air cooler needs to add a dehydrator, which wastes the raw materials of the dehydrator. Moreover, while increa...
