Description
Technical Field
The invention relates to the field of spraying of air coolers, in particular to a splash-proof evaporative air cooler.
Background
With the energy saving, consumption reduction and water saving becoming common people and profoundly influencing the development of various industries, the evaporative air cooler has replaced water coolers in many fields with the obvious advantages of small investment, low power consumption and low water consumption. Especially, by taking advantage of the air cooler, after the water-saving evaporative air cooler is formed by upgrading the air cooling fins, the water-saving evaporative air cooler has more obvious water-saving advantage, and the water-saving evaporative air cooler becomes a mainstream product in the field of heat exchangers at present.
Under the background, the further water saving of the evaporative air cooler has practical significance. The water consumption of the evaporative air cooler is divided into useful water consumption and useless water consumption. The water consumption for taking away heat by means of water evaporation heat exchange can be called as useful water consumption, the water consumption which does not work on the evaporation heat exchange is useless water consumption, and the water consumption generated by splashing of spraying water impacting a water tank belongs to the useless water consumption. At present, the protection measure aiming at splashing water consumption is to add a water splashing prevention structure at an air inlet shutter to intercept splashing water drops, so that the problem of splashing of the water drops is solved to a certain extent, but a new problem that wind is blocked and air inlet is blocked is generated at the same time.
Disclosure of Invention
The invention aims to provide a splash-proof evaporative air cooler which can prevent water from splashing in a water tank, does not influence the air inlet effect and improves the heat exchange capacity of equipment.
In order to achieve the purpose, the technical scheme of the invention provides a splash-proof evaporative air cooler which comprises an air draft mechanism, a spraying device, a tube bundle, an air inlet shutter and a water tank, wherein the tube bundle comprises a plurality of groups of heat exchange coil pipes, each group of heat exchange coil pipes are divided into an air cooling coil pipe section, a light pipe wet cooling coil pipe section and a splash-proof water wet cooling coil pipe section from top to bottom, the spraying device is positioned between the air cooling coil pipe section and the light pipe wet cooling coil pipe section, the splash-proof water wet cooling coil pipe section is a hydrophobic split finned pipe, and the air inlet shutter is provided with a splash-proof structure.
The technical effect of the scheme is as follows: because the spray device is positioned below the air-cooled coil pipe section, the process medium firstly flows into the air-cooled coil pipe section to perform dry heat exchange with air, thereby saving the evaporation water consumption; then, the medium flows into the wet cooling coil pipe section of the light pipe, and the spray water covers the whole coil pipe group, the section is wet evaporation heat exchange, and the heat is taken away mainly by the evaporation heat exchange of the water; finally, the medium flows into the splash-proof wet cooling coil pipe section, the heat exchange form of the section is basically the same as that of the light pipe wet cooling coil pipe section, and the difference lies in that the water drainage split type fins are arranged outside the pipe, so that the heat exchange area is increased, simultaneously, a large water column which is sprayed from the upper part and is downwards is split into a plurality of strands of small water drops, the impact force of the sprayed water entering the water tank is reduced, and a good splash-proof effect is achieved. After the splash-proof structure is cancelled at the air inlet shutter, the ventilation area is increased, the ventilation resistance is reduced, and the ventilation volume is increased. After the spray water stops spraying in winter, the heat exchange capacity of the equipment is further improved compared with that of a non-finned wet cooling coil pipe due to the fact that the anti-splashing water wet cooling coil pipe is provided with the fins.
Furthermore, the splash-proof wet cooling coil pipe section is a hydrophobic split finned pipe, the surface of fins is smooth, the long-time anti-scouring deformation capacity is achieved, the fin spacing is 2-100 mm, and the fins are arranged at equal intervals or at unequal intervals. The technical effect of the scheme is as follows: air almost enters the coil pipe through the fins without obstruction for heat exchange, the spraying water column is divided into fine water drops by the fins, the impulsive force of the water drops entering the water tank is small, and useless water consumption caused by splashing can be avoided.
Furthermore, the fin material of the splash-proof wet cooling coil pipe section is metal or plastic. The technical effect of the scheme is as follows: can select the fin of different materials to cut apart the water column that sprays according to different parent tube materials and external environment.
Further, the air-cooled coil pipe section can be eliminated. The technical effect of the scheme is as follows: the configuration of the air-cooled coil pipe section can be cancelled aiming at the process which is not suitable for using the air-cooled coil pipe section for heat exchange.
