Self-bearing detachable plate-type evaporation air cooler with down-streaming air and spray water

Abstract

The invention discloses a self-bearing detachable plate-type evaporation air cooler with down-streaming air and spray water, which comprises a spraying device, a heat exchange plate bundle, a water tank, a fan and a circulating water pump, wherein the heat exchange plate bundle consists of a plurality of sheet-tube units; each sheet-tube unit consists of two sheets, which are pressed with a plurality of concave and convex foams arranged in a honeycomb shape; spot welding is adopted at the positions of the concave foams and seam welding is adopted at two long sides in a length direction of the sheets so as to form the prolate sheet-tube units after being welded; the two ends of each sheet-tube unit are welded with a small inflowing water collecting tube and a small discharged water collecting tube with threaded joints respectively; and the small inflowing water collecting tube and the small discharged water collecting tube are in sealing connection with a large inflowing water collecting tube and a large discharged water collecting tube with the threaded joints through connecting tubes respectively. In the self-bearing detachable plate-type evaporation air cooler, the two sheets of each sheet-tube unit are provided with the concave and convex foams which are arranged in the honeycomb shape and the spot welding is adopted at the positions of the concave foams, which enhances the strength and bearing capacity of the sheets; and the self-bearing detachable plate-type evaporation air cooler is simple and light in structure because the sheet-tube units does not need restricting by pressing plates, and is convenient in pressure test, assembly, exchange and maintenance because the small inflowing water collecting tube and the small discharged water collecting tube of the sheet-tube units with the threaded joints can be detached from the large inflowing water collecting tube and the large discharged water collecting tube.

Description

technical field [0001] The invention relates to a plate-type evaporative air cooler, in particular to an air cooler with air and spray water arranged in parallel, capable of independently bearing pressure and detachable in structure, using corrugated plate bundles as heat transfer elements, and utilizing evaporation to enhance heat transfer. Background technique [0002] The heat transfer elements of the existing evaporative air cooler are mainly light tube bundles, which generally have the disadvantages of low heat transfer efficiency, heavy weight, fouling, dust accumulation, short life and large floor space. Although the plate type evaporative air cooler can overcome the tube Part of the shortcomings of the evaporative air cooler, but it is a whole welded type, the structure cannot be disassembled, and the plate bundle needs to be restrained by external force, so the structure is complicated, the equipment is heavy, and the production and maintenance are inconvenient.

[0002] The heat transfer elements of the existing evaporative air cooler are mainly light tube bundles, which generally have the disadvantages of low heat transfer efficiency, heavy weight, fouling, dust accumulation, short life and large floor space. Although the plate type evaporative air cooler can overcome the tube Part of the shortcomings of the evaporative air cooler, but it is a whole welded type, the structure cannot be disassembled, and the plate bundle needs external force constraints, so the structure is complicated, the equipment is heavy, and the production and maintenance are inconvenient.

Moreover, the arrangement of air and spray water in the existing evaporative air coolers is mostly carried out in a countercurrent manner, that is, the air flow flows upward, and the spray water flows downward. Poor, the air inlet tube bundle is easy to scale, the spray device is not easy to maintain, and it is difficult to remove scale, etc.
