The outer pipe is made of an efficient hot-dip galvanizing steel pipe with the inner wall provided with the micro-fin strengthened surface. The novel sleeve evaporative condenser has the advantages of being high in heat transmission coefficient, strong in heat exchange performance and resistant to erosion.

Description

A kind of new type tube-in-tube evaporative condenser
Technical field
The utility model relates to a kind of new type tube-in-tube evaporative condenser, belongs to art of refrigeration units.
Background technology
Condenser is delivered to cooling medium with the heat of the high-temperature high-pressure refrigerant steam of compressor discharge in the compression-type refrigerating system, and the quality of its performance has important impact to the overall performance of refrigeration system.Condenser commonly used mainly contains 3 kinds of patterns, i.e. water-cooled condenser, air-cooled condenser and evaporative condenser.Water-cooled condenser discharge is larger, and air cooled condenser is because the heat exchanging fluid of a side is air, so that whole heat transfer coefficient is less, the overall performance of heat exchanger is not high.Evaporative condenser directly utilizes evaporation of water latent heat to carry out heat exchange, has obvious energy-saving effect aspect operation.Yet in most of the cases the outer moisture film of evaporative condenser heat exchange coil becomes the main thermal resistance of heat exchange, and the heat of tube refrigerant can not be delivered to external environment rapidly, so that whole heat transfer coefficient is not very high, volume is usually huger.Simultaneously, so that present evaporative condenser also is mainly used in take ammonia refrigeration system as main industrial refrigeration field, the example of its application is rare in the business air conditioner refrigeration system owing to the reason of the aspects such as manufacturing process and requirement for anticorrosion.
The utility model content
The utility model purpose is to solve the deficiencies in the prior art, and the new type tube-in-tube evaporative condenser that a kind of heat transfer coefficient is high, heat exchange property is strong is provided.
The utility model technical scheme that adopts of dealing with problems is:
A kind of new type tube-in-tube evaporative condenser, comprise one by the vertical cabinet of shaped steel and welded steel plate, the middle part of casing is heat exchanger tube, this heat exchanger tube is comprised of inner and outer tubes and adopts arranged off-centre to form sleeve type structure, the bottom of casing is a water-collecting tray, be provided with ball-cock assembly in the water-collecting tray, the side of water-collecting tray connects water circulating pump, water circulating pump links to each other with upper hose, upper hose is connected with water-locator, and this water-locator is provided with at least 4 spray header outlets, and described water-locator is arranged on the heat exchanger top, the casing top is provided with blower fan, is provided with water fender between blower fan and the water-locator.
Further setting as such scheme: described inner tube adopts outer wall to have the copper pipe of little rib strengthening surface.
Further setting as such scheme: described outer tube adopts inwall to have the galvanizing steel pipe of little rib strengthening surface.
The beneficial effects of the utility model are: by changing the structure of condenser heat exchange coil, make it in limited space, obtain larger heat exchange area, thereby realize the densification of evaporative condenser, compare with common evaporative condenser, the utility model not only carries out the latent heat exchange in the outside of heat exchanger tube, and also carry out heat exchange in the inside of heat exchanger tube, so that heat transfer space strengthens, the type of flow of inner tube recirculated water and cold-producing medium is reflux type simultaneously, the coefficient of heat transfer is large, and the heat exchange property of condenser strengthens.Simultaneously, inner tube adopts outer wall to have the efficient copper pipe of little rib strengthening surface, and outer tube then can adopt inwall to have the efficient galvanizing steel pipe of little rib strengthening surface, further improves the compactness of this condenser, and solves the problem of heat-exchanging tube bundle corrosion.
Description of drawings
Fig. 1 is condenser heat-exchange pipes cross section structure schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 2, a kind of new type tube-in-tube evaporative condenser, comprise one by the vertical cabinet 1 of shaped steel and welded steel plate, the middle part of casing 1 is heat exchanger tube 2, as shown in Figure 1, this heat exchanger tube 2 is comprised of inner tube 21 and outer tube 22 and adopts arranged off-centre to form sleeve type structure, the bottom of casing 1 is a water-collecting tray 3, is provided with ball-cock assembly 4 in the water-collecting tray 3, and the side of water-collecting tray 3 connects water circulating pump 5, water circulating pump 5 links to each other with upper hose 6, upper hose 6 is connected with water-locator 7, and this water-locator 7 is provided with at least 4 spray header outlets, and described water-locator 7 is arranged on heat exchanger 2 tops, casing 1 top is provided with blower fan 8, is provided with water fender 9 between blower fan 8 and the water-locator 7.
Heat exchanger tube 2 is comprised of inner tube 21 and outer tube 22, has howed inner tube 21 than the heat exchanger tube inside of common evaporative condenser, has utilized more fully inner heat transfer space, so that a part of heat of cold-producing medium can pass to the cooling water in the inner tube 21.Consider that cold-producing medium can form stratified flow when condensing in outer tube 22, flooded by bottom liquid pool in the outer tube in order to prevent inner tube 21 that this sleeve type structure has adopted arranged off-centre.During the condenser operation, the refrigerant vapour of HTHP enters the circular passage that inner and outer pipes forms, and condenses at the outer wall of inner tube 21 and the inwall of outer tube 22, with the cooling water that flows in the heat transferred inner tube 21 and the cooling moisture film that sprays on outer tube 22 outer walls.And the cooling moisture film is identical with traditional evaporative condenser with caloic transmittance process between the air on outer tube 22 outer walls.Obviously, this telescopic heat exchange coil structure is so that had more the heat exchange area of interior tube portion at same heat exchange volume internal ratio single tube structure, thereby the evaporative condenser of more traditional single tube structure has more compact structure; Simultaneously, the inner tube 21 here can adopt outer wall to have the efficient copper pipe of little rib strengthening surface, 22 of outer tubes can adopt inwall to have the efficient galvanizing steel pipe of little rib strengthening surface, further improve the compactness of this condenser, and solve the problem that heat exchanger tube 2 is corroded easily.
