A cooler is a type of heat exchange equipment used to cool fluids. Usually water or air is used as a coolant to remove heat. There are partition coolers, spray coolers, jacket coolers and tube coolers. It is widely used in high-power silicon rectifier and large electrical equipment such as induction furnace and intermediate frequency furnace as a pure water, water-air, oil-water and oil-air cooling device for cooling protection auxiliary machines. Cooler is a heat exchange device commonly used in metallurgy, chemical industry, energy, transportation, light industry, food and other industrial sectors.
How the cooler works
1. The structural principle of the cooler: The detachable cooler is made of many stamped corrugated sheets at certain intervals, sealed around by gaskets, and overlapped and compressed with a frame and a compression screw. The four corners of the plate and the gasket are The holes form the distribution pipes and collecting pipes of the fluid, and at the same time reasonably separate the hot and cold fluids, so that they flow in the flow channels on both sides of each plate respectively, and conduct heat exchange through the plates.
2. The heat exchange principle of the cooler: The cooler is a kind of cooler formed by pressing thin metal plates into heat exchange plates with a certain corrugated shape, then stacking them, and tightening them with plywood and bolts. Thin rectangular channels are formed between the various plates, and heat is exchanged through the half plates. The working fluid flows through the narrow and tortuous channel formed between the two plates. The hot and cold fluids pass through the flow channel in turn, and there is an interlayer plate in the middle to separate the fluids, and heat exchange is carried out through this plate.
Cooler installation method
The installation methods of coolers are divided into vertical coolers and horizontal coolers. Vertical coolers have the characteristics of small installation area and convenient installation. The horizontal oil cooler has the characteristics of small pressure drop and strong water impact resistance. Therefore, according to the requirements of different sites, space heights, and performance, the correct selection of vertical or horizontal oil coolers can better meet the requirements of the generator set. and other equipment needs.
(1) The cooler can only be put into use after passing the pressure test, and the internal water storage in the front row should be exhausted.
(2) Check whether the pouring and venting valves are flexible and easy to use and the switch positions, and whether the pressure gauges and thermometers are all installed.
(3) Check whether the foundation and support are firm, and whether the bolts of each part are fully buckled and fastened.
(4) When put into use, first put the cold flow, and then put the hot flow.
(5) When using cold medium or hot medium, first ensure that the auxiliary line is unblocked, and then slowly open the outlet valve. After checking that there is no problem, open the inlet valve. It must be opened slowly to prevent pressure. During the commissioning process, pay attention to observe the changes of the equipment. After the cooler is put into use, with the change of temperature and pressure, leakage may occur, and it should be checked in time.
