The utility model content
The utility model provides a kind of plate-fin evaporation air cooler for solving the traditional fin tube type evaporation air cooler and the general character defective of plate type evaporation air cooler;
The utility model mainly by: air-introduced machine, air duct member, shower water assembly, outlet bobbin carriage, water circulating pump device, header tank, housing, plate-fin plate bundle, import bobbin carriage, receive the water demister and constitute.
The technical scheme of the utility model technical solution problem is: plate-fin plate bundle two ends become the connected component bobbin carriage with the import bobbin carriage with the outlet box-shaped respectively; Plate-fin plate bundle is arranged on the import bobbin carriage and exports in the bobbin carriage, constitutes bobbin carriage, and bobbin carriage is arranged on the housing middle part, and ring week is fixedly connected; It is hinged that the shower water water supply pipeline is arranged on the shower water component level water distributor of the top of bobbin carriage in housing one side and the housing, receives the water demister and be arranged on shower water assembly top; The air duct member is arranged on receives water demister top; The top of air duct member is provided with air-introduced machine; The water circulating pump device is fixed on housing one side-lower; The below is provided with the cleaning water source that header tank provides process to filter for the water circulating pump device in the housing; Said apparatus promptly constitutes a kind of plate-fin evaporation air cooler described in the utility model.
Described plate-fin plate bundle two ends become connected component with the import bobbin carriage with the outlet box-shaped respectively;
Described import bobbin carriage is provided with the bypass inlet of processing medium fully;
Described outlet bobbin carriage is provided with the bypass outlet of processing medium equally fully;
Said apparatus promptly constitutes a kind of plate-fin evaporation air cooler described in the utility model.
The fin pattern of described plate-fin plate bundle can be divided into: flat type fin, porous type fin, serrated fin, rippled fin, flap type fin;
The material of described plate-fin plate bundle can be: stainless steel, titanium material etc.;
Described plate-fin plate bundle is to form by the vacuum brazing manufacturing;
Described plate-fin tube sheet heat transfer type be cross-flow or wrong adverse current, one way or multipass frame mode.
Operation principle of the present utility model is: the utility model is in the heat and mass course of work, and air-flow direction and processing medium flow direction form cross-flow or wrong adverse current; Processing medium flows and is one way or multipass; Increase the secondary heat transfer area, the augmentation of heat transfer effect.
The beneficial effects of the utility model: the utility model plate-fin evaporation air cooler is a kind of new and effective, compact, energy-conservation condensation cooling device that integrates plate-fin heat exchanger and evaporative air-cooling formula heat exchanger advantage.
Its maximum characteristics are characterised in that: the plate-fin plate bundle that adopts stainless steel or titanium material to make replaces fin tube type or the board-like tube bank in conventional tubular evaporation air cooler or the plate type evaporation air cooler, breaks through the restriction on structure and heat transfer property of traditional fin tube type or plate type evaporation air cooler.
The utility model plate-fin evaporation air cooler has heat transfer efficiency height, compact conformation, floor space is little, circulation area is big, flow resistance is low, in the pipe bearing capacity good, can maximize and technical performance that modularization etc. is excellent.It is a kind of new and effective condensation cooling device of domestic initiation.
Adopt the utility model can solve the problem of many newly-built or extending capacity reformation device place wretched insufficiencies, require low occasion, have more the advantage that other evaporation air cooler hardly matches in pressure drop.
The utility model plate-fin evaporation air cooler is the ideal product of dry type or wet air cooler upgrading in the heat exchange industries such as modern oil refining, chemical industry, electric power, nuclear energy and metallurgy.
Under current water globe resource, energy-intensive situation, the utlity model has wide application prospect.
Because the manufacturing process of plate-fin plate bundle of the present utility model adopts Vacuum Soldering Technology, to manufacturing equipment and technological requirement height, cost is slightly high.But along with technological progress, these problems will be readily solved.
