AI Technical Summary
The existing composite flow evaporation condensers have small air inlet area and high wind speed, which leads to easy return of humid and hot air flow, low coil utilization, and the same flow of air flow and spray water flow are not conducive to heat transfer, small air outlet size leads to air flow bottleneck, and large fan power consumption.
A composite multi-dimensional flow evaporation condenser is designed to add side air inlets and top air inlets. The spraying system evenly sprays water onto the evaporation condensation coil, forming a cross between vertical air flow and transverse air flow, increasing the inlet and air outlet area, and reducing the air flow rate.
The air inlet and outlet area of the evaporation condensation coil is significantly increased, the airflow distribution is more uniform, the fan power consumption is reduced, the coil utilization rate is increased, the heat transfer coefficient is increased, and the evaporation rate is increased.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of condensers, and particularly relates to a composite multi-dimensional flow evaporative condenser. Background Art
[0002] At present, the air flow of the known composite flow evaporative condenser is a unidirectional flow, and there are two air inlets in total. The air inlet of the evaporation and condensation coil is at the top of the equipment, above the spraying device, and the air inlet of the pre-cooling filler is on the lower side elevation of the equipment.
[0003] The above-mentioned composite flow evaporative condenser has the following deficiencies:
[0004] 1. The only air inlet of the evaporation and condensation coil is at the top of the equipment, and the air inlet area is small, the wind speed is high, and the hot and humid air flow discharged by the fan is easy to flow back.
[0005] 2. The air flow entering from the upper part of the evaporation and condensation coil flows out horizontally from the lower side of the coil. There is a dead zone in the coil on the inner side of the lower air outlet, and there is no air flow passing through, no evaporation and heat dissipation, and the utilization rate of the coil is low.
[0006] 3. The air flow and the spraying water flow flow in the same direction, and the water film covering the surface of the coil has little agitation, which is not conducive to heat transfer.
[0007] 4. In order to avoid short circuit, the size of the air outlet of the evaporation and condensation coil is small, resulting in an air flow bottleneck, and the power consumption of the fan motor is large. Content of the Utility Model
[0008] The utility model provides a composite multi-dimensional flow evaporative condenser, which can solve the problems pointed out in the background art.
[0009] A composite multi-dimensional flow evaporative condenser includes a condenser body, a spraying system, an evaporation and condensation coil, a side air inlet, an air outlet, a top air inlet, a side pre-cooling filler air inlet and a pre-cooling filler. The spraying system evenly sprays the spraying water onto the evaporation and condensation coil. A top air inlet is opened at the corresponding position of the top of the condenser body and the evaporation and condensation coil. A side air inlet is opened at the corresponding position of the side of the condenser body and the evaporation and condensation coil. The side pre-cooling filler air inlet is located below the side air inlet and is correspondingly arranged with the pre-cooling filler.
[0010] Preferably, the spraying system includes a spraying pipeline, a plurality of spray heads, a spraying water water tank and a circulating water pump. The spray heads are arranged above the evaporation and condensation coil and are evenly sprayed through the spray heads. The spraying water water tank is below the evaporation and condensation coil.
[0011] Beneficial Effects: The utility model provides a composite multi-dimensional flow evaporative condenser.
[0012] 1. The air inlet area and air outlet area of the evaporation condensation coil are significantly increased, the air flow velocity is reduced, the air flow distribution is more uniform, and the power consumption of the fan is reduced.
[0013] 2. The air flow velocity at the top of the evaporation condensation coil is reduced, avoiding the backflow of the hot and humid air discharged by the fan.
[0014] 3. There are vertical and horizontal air flow intersections on the surface of the evaporation condensation coil, the water film on the coil surface is disturbed, the heat transfer coefficient is increased, and the evaporation rate is improved.
[0015] 4. The dead zone where there is no air flow through the evaporation condensation coil is eliminated, and the utilization of the coil is improved. Description of the Drawings
