The cooler is a kind of high efficiency heat exchanger which is made up of a series of corrugated metal sheets. Thin rectangular channels are formed between various plates for heat exchange through the plates. Heat exchanger is liquid - liquid, liquid - steam heat exchange ambition equipment. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than the tubular heat exchanger, covers an area of one-third of the tubular heat exchanger, and the heat recovery rate can be as high as 90%.

Cooler repair and maintenance: with the continuous development of heating skills, heat exchanger has become a necessary equipment in People's Daily life, but whether it is imported heat exchanger there will always be scaling and blockage, it is very important for heat exchanger cleaning. In the use of heat exchanger, because of improper operation of water treatment equipment and lax control of water quality, the circulating water that does not meet the water quality standards is injected into the heat exchanger, and the calcium and magnesium carbonate in the water is decomposed into calcium carbonate and magnesium hydroxide precipitate when heated. Some of these sediments are bonded to the heating surface of the heat exchanger, forming a strong scale; The other part is suspended in circulating water and deposited on the heating surface with low flow rate, forming secondary scale. Because of the poor thermal conductivity of scale, the heat transfer of heat exchanger deteriorates, the heat transfer efficiency is greatly reduced, and the severe waste of heat energy is formed. So the heat exchanger to regular protection and maintenance.

The characteristics of heat exchanger: 1, compact structure, space saving: detachable heat exchanger structure planning is compact, small size, compared with shell and tube heat exchanger, can save 50%-80% space. 2, energy saving, high efficiency: the same operating conditions, the need for less cooling medium. Therefore, at the same working condition, the push work of demand is less. 3, low repair cost, convenient maintenance: modular planning, convenient repair, such as damage can be replaced by a single module, more economic.

Principle of operation: detachable heat exchanger is an efficient wall type heat exchange equipment, composed of a number of metal corrugated plates arranged alternately, through the rubber sealing gasket formed cold and hot channel, to achieve full countercurrent heat exchange.
