Abstract

The invention discloses an intersected direct-current dew point indirect evaporative cooler, and particularly relates to an intersected direct-current indirect evaporative cooler which can lower air temperature to be below the wet bulb temperature to approach dew point temperature and is applied to an air conditioner, aiming at solving the technical problems that conventional dew point indirect evaporative coolers are easy to generate a negative pressure zone and are great in energy consumption. The cooler comprises three regular six-face indirect evaporative cooling units which are respectively a unit A, a unit B and a unit C, wherein the unit A, the unit B and the unit C are in two-to-two butt joint, the first layer of passage of the unit A communicates with the first layer of passage of the unit B, the third layer of passage of the unit A communicates with the third layer of passage of the unit C, and the second layer of passage of the unit B communicates with the second layer of passage of the unit C. After adopting the technical scheme, the cooler can remarkably improve the heat exchange efficiency and can output air with temperature approaching to dew point temperature, thus effectively solving the difficulty that air is output while approaching to the dew point temperature and reducing air flowing resistance.

Background technology

Evaporative Cooling Air Conditioning technology is the air-conditioning technical utilizing water evaporation endothermic to freeze, a kind of environmental protection of cold, efficient, the economic type of cooling is obtained by the hot and humid area of water Yu air, there is energy-saving and environmental protection, efficient, economic dispatch feature, this technology can be greatly lowered power consumption, does not have the risk of contaminated environment simultaneously.

Traditional dew point indirect evaporative cooler mostly is counter flow type structure, and this will cause that working gas enters evaporator section hourly velocity direction after carrying out pre-cooling and changes, and then produces negative pressuren zone, adds energy consumption.

Summary of the invention

The technical problem to be solved in the present invention is traditional dew point indirect evaporative cooler, is easily generated negative pressuren zone, and energy consumption is big, it is provided that a kind of gas flowing does not all occur velocity attitude to change, and flow resistance is little, the intersection single flow dew point indirect evaporative formula cooler that energy consumption is low.

nullFor achieving the above object，The present invention adopts following technical proposals: a kind of single flow dew point indirect evaporative formula cooler that intersects，Indirect evaporating-cooling unit including three positive six faces,Respectively unit A、Unit B、Unit C,Described unit A includes three layers，Every layer is provided with a passage，Respectively unit A ground floor passage、Unit A second layer passage、Unit A third layer passage，Described unit B includes two-layer，Every layer is provided with a passage，Respectively unit B ground floor passage and unit B second layer passage，Described unit C includes two-layer，Every layer is provided with a passage，Respectively unit C second layer passage and unit C third layer passage，Wherein，Described unit A、Unit B and unit C dock between two，Described unit A ground floor passage and unit B ground floor channel connection，Unit A third layer passage and unit C third layer channel connection，Unit B second layer passage and unit C second layer channel connection.

Described unit A ground floor passage, unit A third layer passage, unit B second layer passage and unit C third layer passage are dry passage, and unit A second layer passage, unit B ground floor passage, unit C second layer passage are wet channel.

The height that the unit A of described positive six face, unit B, the unit C length of side are 0.8-1.2m, dry passage and wet channel is 5-15mm.

The unit A of described positive six face, unit B, unit C are aluminium material.

It is provided with absorbent material in the wet channel of described positive six face.

The present invention adopting said structure can make heat exchange efficiency significantly improve, output gas temperature can be cooled to below wet bulb temperature, close to dew point temperature, all gas flowing does not all occur velocity attitude to change, efficiently solve and reduce air flow resistance close to the output gas of dew point temperature obtaining simultaneously, the problem reducing the energy consumption of dew-point indirect evaporation cooler further.

Detailed description of the invention

nullAs shown in Figures 1 to 5，The present invention includes the indirect evaporating-cooling unit of three positive six faces,Respectively unit A、Unit B、Unit C,Described unit A includes three layers，Every layer is provided with a passage，Respectively unit A ground floor passage 11、Unit A second layer passage 12、Unit A third layer passage 13，Described unit B includes two-layer，Every layer is provided with a passage，Respectively unit B ground floor passage 21 and unit B second layer passage 22，Described unit C includes two-layer，Every layer is provided with a passage，Respectively unit C second layer passage 32 and unit C third layer passage 33，Wherein，Described unit A、Unit B and unit C dock between two，Described unit A ground floor passage 11 connects with unit B ground floor passage 21，Unit A third layer passage 13 connects with unit C third layer passage 33，Unit B second layer passage 22 connects with unit C second layer passage 32.

Described unit A ground floor passage 11, unit A third layer passage 13, unit B second layer passage 22 and unit C third layer passage 33 are dry passage, and unit A second layer passage 12, unit B ground floor passage 21, unit C second layer passage 32 are wet channel.

The unit A of described positive six face, unit B, unit C are aluminium material.Aluminium material can also be replaced by the material that other heat conductivity is good, such as copper, ferrum, aluminium alloy etc..

It is provided with absorbent material in the wet channel of described positive six face.Absorbent material can be the good materials of water absorption such as sponge, water-absorbing resin, silica gel, needs to supply water in absorbent material endlessly in cooling procedure.

Below in conjunction with accompanying drawing 5, the present invention is described in detail.

During use, for the cooling effect reached, many group unit A, unit B and unit C can use in superposition.As it is shown in figure 5, surrounding air is entered by A1, A2, A3 and B1 side, A1 side gas is discharged by A4 side through wet channel unit A second layer passage 12；A2 side gas is discharged through C1 side after entering dry passage unit C third layer passage 33 after dry passage unit A third layer passage 13 pre-cooling；A3 side gas is discharged through B2 side after entering wet channel unit B ground floor passage 21 after dry passage unit A ground floor passage 11 pre-cooling；B1 side gas enters after dry passage unit B second layer passage 22 pre-cooling and discharges through C2 side after wet channel unit C second layer passage 32, and each side ring border air flow path and unit A, unit B, unit C each dry and wet passage corresponding relation are as shown in table 1.Owing to being provided with absorbent material in wet channel, flow through the surrounding air evaporation endothermic of wet channel and then by thermal convection current to flowing through the dry passage environment air cooling-down of unit A, unit B or unit C, and flow through the surrounding air of wet channel owing to being discharged outdoor containing certain humidity.The present invention is expelled directly out outdoor by A4, B2, C2 side expellant gas under the effect in outside air channel, only retains the air discharged C1 side as output gas, for indoor offer cold wind.Cooled down further by the gas entering wet channel unit C second layer passage 32 after dry passage unit B second layer passage 22 pre-cooling again when gas after dry passage unit A third layer passage 13 pre-cooling is discharged, make to be cooled to below wet bulb temperature by C1 side expellant gas temperature, close to dew point temperature.
