The technical problem to be solved in the present invention is traditional dew point indirect evaporative cooler, is also easy to produce negative pressuren zone, and energy consumption is big, A kind of gas flowing is provided velocity attitude change does not occur, flow resistance is small, and the low intersection single flow dew point of energy consumption steams indirectly Hairdo cooler.

To achieve the above object, the present invention uses following technical proposals：It is cold that one kind intersects single flow dew point indirect evaporative formula But device, the indirect evaporating-cooling unit of three positive six faces, respectively unit A, unit B, unit C, described unit A bags are included Three layers are included, every layer is provided with a passage, and respectively unit A first layers passage, unit A second layers passage, unit A third layer is led to Road, described unit B include two layers, and every layer is provided with a passage, and respectively unit B first layer passage and the unit B second layer leads to Road, described unit C include two layers, and every layer is provided with a passage, and respectively unit C second layers passage and unit C third layer leads to Road, wherein, described unit A, unit B and unit C are docked two-by-two, and joint is provided with dividing plate, described unit A first layers two-by-two Passage connects with unit B first layer passage, and unit A third layer passage connects with unit C third layer passages.

Described unit A first layers passage, unit A third layer passage, unit B second layer passage and the unit C second layers leads to Road is dry passage, and unit A second layers passage, unit B first layer passage, unit C third layer passage are wet channel.

Unit A, unit B, a height of 5- that the unit C length of sides are 0.8-1.2m, dry passage and wet channel of the positive six face 15mm, dividing plate thickness are 0.2-2mm.

Unit A, unit B, the unit C of the positive six face are aluminium material.

Absorbent material is provided with the wet channel of the positive six face.

Heat exchange efficiency can be significantly improved using the present invention of said structure, output gas temperature can be cooled to wet bulb temperature Below degree, close to dew-point temperature, velocity attitude change does not occur for all gas flowing, efficiently solves and is obtaining close to dew point The output gas of temperature reduces air flow resistance simultaneously, and the further energy consumption for reducing dew-point indirect evaporation cooler is asked Topic.

Embodiment

As shown in Figures 1 to 5, the indirect evaporating-cooling unit of the invention for including three positive six faces, respectively unit A, Unit B, unit C, described unit A include three layers, and every layer is provided with a passage, respectively unit A first layers passage 11, unit A second layers passage 12, unit A third layer passage 13, described unit B include two layers, and every layer is provided with a passage, are respectively single First B first layers passage 21 and unit B second layer passage 22, described unit C include two layers, and every layer is provided with a passage, respectively For unit C second layers passage 32 and unit C third layer passage 33, wherein, described unit A, unit B and unit C are docked two-by-two, Joint is provided with dividing plate 40 two-by-two, and described unit A first layers passage 11 connects with unit B first layer passage 21, unit A the 3rd Layer passage 13 connects with unit C third layer passage 33.

Described unit A first layers passage 11, unit A third layer passage 13, unit B second layer passage 22 and unit C Double layer channel 32 is dry passage, and unit A second layers passage 12, unit B first layer passage 21, unit C third layer passage 33 are wet Passage.

Unit A, unit B, the unit C of the positive six face are aluminium material.Aluminium material can also be good by other thermal conductivity Material replaces, such as copper, iron, aluminium alloy.

Absorbent material is provided with the wet channel of the positive six face.Absorbent material can be sponge, water-absorbing resin, silica gel etc. The preferable material of water imbibition, need in cooling procedure endlessly toward supplying water in absorbent material.

5 the present invention is described in detail below in conjunction with the accompanying drawings.

In use, being the cooling effect reached, multigroup unit A, unit B and unit C can be superimposed use.Such as Fig. 5 institutes Show, surrounding air is entered by A1, A2, A3, B1 and C3 side, and A1 sides gas is arranged through wet channel unit A second layers passage 12 by A4 sides Go out；A2 sides gas enters after wet channel unit C third layer passage 33 through C2 sides after the precooling of dry passage unit A third layer passage 13 Discharge；A3 sides gas enters after wet channel unit B first layer passage 21 through B2 after the precooling of dry passage unit A first layers passage 11 Discharge side；B1 sides gas is discharged after dry passage unit B second layer passage 22 by B3 sides, and C3 sides gas is through dry passage unit C Discharged after double layer channel 32 by C1 sides, each side ring border air flow path is corresponding with unit A, unit B, each dry and wet passages of unit C Relation is as shown in table 1.Due to being provided with the absorbent material containing condensing agent in wet channel, the surrounding air evaporation for flowing through wet channel is inhaled Heat so by thermal convection current to being flowed through environment air cooling-down in unit A, unit B or unit C dry passage, and flow through wet channel Surrounding air containing certain humidity due to being discharged outdoor.The present invention is arranged in the presence of the air channel of outside by A4, B2, C2 side The gas gone out is expelled directly out outdoor, retains the air of B3, C1 side discharge as output gas, is indoor offer cold wind.By through B2, The gas of C2 sides discharge cools down to the air discharged through B3, C1 side respectively, is cooled to the gas temperature for being passed through interior wet Below ball temperature, close to dew-point temperature, two strands of gases are to indoor transmission cold air, and air quantity is big, good refrigeration effect.Each piece of dividing plate 40 Each runner gas is separated, prevents gas from obscuring；Dividing plate between unit B and unit C separates the gas that B3, C1 side are discharged, Cushioning effect is also acted as, prevents the gas collisions that both sides are discharged from producing adverse current, increases energy consumption.

Each side ring border air flow path of table 1 and unit A, unit B, each dry and wet passage corresponding relations of unit C
