Abstract
The utility model provides a heat exchanger of spray evaporative air-cooling equipment, which solves the problems of the heat exchanger of the prior spray evaporative air-cooling equipment such as small heat transfer coefficient and poor heat transfer effect. The heat exchanger comprises a heat exchange light pipe bundle, a support plate and a film enhancing plate, wherein the heat exchange light pipe bundle is fixed on the support plate; the film enhancing plate is arranged between light pipes on the same column; the film enhancing plate is a corrugated plate; and the central plane of the film enhancing plate and the central axis of the adjacent two heat exchange light pipes are on the same plane. When the film enhancing film is a metal plate, the upper end of the film enhancing plate is directly fixed on the lower end of the heat exchange light pipe on the above layer; and the film enhancing film is fixed on the support plate when the film enhancing plate is a non-metal plate and keeps no contact with the two adjacent heat exchange light pipes. The heat exchanger has the advantages that the heat exchanger can improve the heat exchange capacity and the work efficiency without changing the operation energy consumption of the air-cooling equipment, or the heat exchanger can reduce the operation energy consumption of the air-cooling equipment when completing the same heat exchange capacity.
Description
Technical field
The utility model relates to a kind of spraying and sprinkling evaporation type air cooling equipment, relates to a kind of heat exchanger of spraying and sprinkling evaporation type air cooling equipment particularly.
Background technology
The operation principle of heat-exchanging tube bundle is in the spraying and sprinkling evaporation type air cooling equipment, and shower water forms moisture film on the light pipe of heat-exchanging tube bundle surface, so that evaporation, water film evaporation is a phase transition process, the heat of medium in its a large amount of absorption tube, thus reach the purpose of medium in the cooling tube.The patent of patent No. ZL200620098211.4 has been introduced and has been had the surface evaporation air cooling heat exchanger that increases lamina membranacea, comprise heat exchange plain tube bank, support plate and increase lamina membranacea, the heat exchange plain tube bank is fixed on the support plate, add between the heat exchange light pipe and increase lamina membranacea, the shower water that pipe is dripped down is increasing lamina membranacea upper berth generate film, with the heat transfer area of increase shower water and moving air, but this type of heat transfer area and heat-transfer effect of increasing lamina membranacea are still not ideal enough.
Summary of the invention
The purpose of this utility model is that to solve in the existing spraying and sprinkling evaporation type air cooling equipment heat exchanger heat transfer coefficient little, and the problem of heat-transfer effect difference provides a kind of heat exchanger of spraying and sprinkling evaporation type air cooling equipment.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of heat exchanger of spraying and sprinkling evaporation type air cooling equipment, comprise heat exchange plain tube bank, support plate and increase lamina membranacea, the heat exchange plain tube bank is fixed on the support plate, be provided with between same column light pipe and the light pipe and increase lamina membranacea, the described lamina membranacea that increases is a corrugated sheet, and the central axis that increases lamina membranacea central plane and adjacent two heat exchange light pipes is on same plane.When increasing lamina membranacea and being metallic plate, the positive lower end of upper strata heat exchange light pipe is fixed in the upper end that increases lamina membranacea when described; , increase lamina membranacea and be fixed on the support plate when increasing lamina membranacea and being non-metal board when described, increase lamina membranacea and adjacent two heat exchange light pipes are contactless.
The utility model installs a corrugated sheet additional between the tube and tube of each row heat exchanger tube, the area of corrugated sheet is except bigger than platen area, and according to a synergistic principle, corrugated sheet also can increase horizontal branch speed, makes shower water bigger to the heat transfer coefficient of air.Compare with flat board, corrugated sheet is all having more advantage aspect heat transfer area and the heat transfer coefficient two.Corrugated sheet can be fixed on the support plate with modes such as welding, slot, screw or bolt connections, also can directly be welded on the heat exchanger tube.
The evaporative air-cooling heat-exchanging tube bundle that described corrugated sheet and pipe are compound, the corrugated sheet wall thickness is thinner, and rigidity is better, and is fine with wettability.The shower water of upper strata light pipe is fallen on the corrugated sheet, and except sensible heat heat transfer, some evaporation enters air, takes away a large amount of heats, thereby the temperature of shower water is descended.Shower water after temperature descends is dropped in down again on one deck pipe, makes that one deck pipe internal-external temperature difference enlarges down, and hot fluid outwards transmits heat quickly in helping managing, thereby has strengthened the heat-transfer capability of evaporative air-cooling equipment.
A kind of corrugated sheet of the present utility model and the compound heat-exchanging tube bundle of pipe, need not increase the tube bank volume, but can significantly increase exchange capability of heat, can be used on hot fluid walks on the interior various spraying and sprinkling evaporation air cooling apparatus of pipe, as cooler, condenser, cooling tower, cooling tower etc., no matter forced air-cooling or natural air cooling all can be used.
The beneficial effects of the utility model are, under the constant situation of air cooling apparatus operation energy consumption, can increase the heat exchange amount, increase work efficiency; Perhaps under the situation of finishing identical heat exchange amount, can save the operation energy consumption of air cooling apparatus.
