Description

Indirect evaporation cooling core body

Technical field

The invention belongs to field of air conditioning, relate in particular to a kind of indirect evaporation cooling core body.

Technical background

Conventional indirect evaporation cooling core body, especially dew point indirect evaporative cooling core body, two passages, be that dry passage and wet channel are arranged vertically, while causing core body processing air quantity larger, the air-flow of core body is difficult to arrange, reason is the direction that the air-flow of a passage passes through, and is the cross-sectional direction of another passage, when increasing the draught area of a passage, will cause the resistance of another passage to strengthen.

Another problem is that transpiration-cooled heat exchange wall generally adopts slab construction, because flat board does not have intensity, so just need to increase and support at interchannel, manufacture difficulty is strengthened, material increases, cost raises, and Fig. 1 is typical dew point evaporative cooling core in US Patent No. 6581402, clearly has two problems above-mentioned.

Summary of the invention

The object of the invention is for the deficiencies in the prior art, proposed a kind of indirect evaporation cooling core body, adopt and have the corrugated plate of some strength as heat exchange wall, corrugated plate interfolded is arranged, is had good intensity, without separately adding support; Simultaneously dry passage and wet channel are arranged in parallel, and dry wet channel airflow direction is parallel, thus do not exist above-mentioned when a cross-sectional area increases, the problem of another channel resistance increase; In addition, core body is divided into some different dry wet channel intake and exhaust region, different intake and exhaust region connects by flow distributor, guarantees that in core body, distribution of air flow is even when can fully increase core body air inlet/outlet like this.

The object of the invention is to be achieved through the following technical solutions: a kind of indirect evaporation cooling core body, by corrugated plate, seal, formed, two ends, the left and right interlaced arrangement seal of every corrugated plate, between two adjacent corrugated plates, form wet channel and dry passage, and in end, forming ventilation zone, dry passage upper end is also sealed by seal.

Further, on described corrugated plate, there is perforate.

Further, being shaped as of described corrugated plate is square, or two formed polygons in angle of square removal, or four formed polygons in angle of square removal.

Further, described corrugated plate material is tectorial paper, overlay film nonwoven, aluminium flake, steel disc.

Further, the corrugation of described corrugated plate and horizontal plane angle are 10-45 degree, and the wave height of corrugation is 3-10mm, two corrugated plate interfolded.

Further, the length L of described passage is 100-500mm, and height H is 50-500mm.

Further, described ventilation zone connects each other by flow distributor.

Further, it is characterized in that, described channel interior also adds wants seal, corresponding from different ventilation zone.

Further, the surface of described corrugated plate is hydrophobic in dry passage one side, in wet channel one side, is hydrophilic.

An indirect evaporation cooling core body, is comprised of corrugated plate, seal, and seal is arranged in one end of every corrugated plate, the other end does not have seal, between two adjacent corrugated plates, form wet channel and dry passage, and form ventilation zone in end, dry passage upper end is also sealed by seal.

The invention has the beneficial effects as follows: simple in structure, flexible, manufacture difficulty of processing little, low cost and other advantages, is applicable to large-scale industrial production.

In figure, corrugated plate 10, seal 11, wet channel 101, dry passage 102, perforate 20, the first ventilation zone A1, the second ventilation zone A2, the 3rd ventilation zone A3, the first flow distributor 31, the second flow distributor 32.

The specific embodiment

Core body basic structure of the present invention as shown in Figure 2 and Figure 3, indirect evaporation cooling core body is by corrugated plate 10, seal 11 compositions such as grade, corrugated plate 10 two ends interlaced arrangement seals 11, form two mutually passages of isolation, i.e. wet channel 101 and dry passage 102, and in end, form ventilation zone, dry passage 102 upper ends are also sealed by seal 11, and wet channel 101 blow-by allow that water enters.

The material of corrugated plate 10 is impermeable material, if the material of corrugated plate 10 is tectorial paper, and overlay film nonwoven, aluminium flake, steel disc etc.

The corrugation of corrugated plate 10 and horizontal plane angle A are 10 to 45 degree, as shown in Figure 6.The wave height of corrugation is 3-10mm, and two corrugated plate 10 interfolded, connect with glue between corrugated plate 10.

The surface of corrugated plate 10 is hydrophobics in dry passage 102 1 sides, in wet channel 101 1 sides, is hydrophilic.

The length L of core body passage is generally 100-500mm, and channel height H is 50-500mm.

Fig. 4 shows and the core body of Fig. 2 different angles, shows that the other end of core body is also added with seal 11.

Fig. 5 shows the situation different from Fig. 4, and the other end of core body is blow-by, is not added with seal 11, and dry passage 102 and wet channel 101 are communicated with.

On the wall of the corrugated plate 10 described in Fig. 6 represents, there is perforate 20.

The shape of corrugated plate 10 can be different shapes, comprise square, or two formed polygons in angle of square removal, or four formed polygons in angle of square removal, what in Fig. 2, represent is square, and Fig. 7, what Fig. 8 represented is two formed polygons in angle of square removal.

Fig. 9 has represented that a passage has the situation of a plurality of portings, as there being 3 ventilation zone in figure, comprises the first ventilation zone A1, the second ventilation zone A2, and the 3rd ventilation zone A3, wherein, the first ventilation zone A1 is connected with a passage with the 3rd ventilation zone A3.

In Figure 10, link together for a plurality of ventilation zone of core body and the first flow distributor 31.

In Figure 11, link together for a plurality of ventilation zone of core body and the second flow distributor 32.

In Figure 12, body channel interior is also added with seal, can allow like this in a passage by two kinds of gases.
