The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The utility model dew point tubular type that shown in Figure 1 is indirectly-structural representation of a kind of embodiment of direct evaporative cooler.Be included in the filter 1, chimney cooler, direct evaporative cooler and the pressure fan 20 that set gradually by the air intake direction in the machine unit shell, chimney cooler is made up of precooling zone and cooling section.
The structure of chimney cooler precooling zone is: comprise the heat exchanger tube family that many staggered heat exchanger tube a2 form; The top of heat exchanger tube family sets gradually overfire air fan a16, water fender a14 and water-locator a11 from top to bottom; On the machine unit shell wall of overfire air fan a16 correspondence overfire air fan air outlet a18 is set; The bottom of heat exchanger tube family is provided with water tank a6, and water tank a6 is connected with water pump a3 and water-locator a11 through pipeline.
The structure of chimney cooler cooling section is: comprise the heat exchanger tube family that many heat exchanger tube b21 form; Heat exchanger tube family middle and upper part heat exchanger tube is staggered; The length of bottom heat exchanger tube reduces from top to bottom successively; The top of heat exchanger tube family is disposed with overfire air fan b17, water fender b15 and water-locator b12 from top to bottom; The machine unit shell wall that overfire air fan b17 is corresponding is provided with overfire air fan air outlet b19, and the bottom of heat exchanger tube family is provided with water tank b7, and water tank b7 is connected with water pump b4 and water-locator b12 through pipeline.
Direct evaporative cooler comprises the water-locator c13 of filler 10, the setting of filler 10 tops and the water tank c8 that filler 10 bottoms are provided with, and water tank c8 is connected with water pump c5 and water-locator c13 through pipeline.
Heat exchanger tube a2 and heat exchanger tube b21 prevent to get into the aqueous reflux in the pipe from cooling section primary air import department heat exchange pipeline certain angle that tilts a little; And the heat exchanger tube section is the inclined plane, prevents that water droplet is in pipe in two subchannels, and the structure of heat exchanger tube a2 and heat exchanger tube b21 is as shown in Figure 2.
In precooling zone and the cooling section, be processed air and separated by heat exchanger tube, be primary air passage and secondary-air passage with the processing air.In each section of cooler movement, primary air from left to right, auxiliary air from lower to upper, primary air and auxiliary air are cross-current; Water is close to wall from top to bottom and is formed moisture film in secondary-air passage, auxiliary air and water form adverse current; Primary air and water are also realized adverse current, and the air flow process signal is as shown in Figure 3.
In the whole system, each functional section is provided with water circuit system separately, and the water system between each section separately; Can open water pump a3, water pump b4 and water pump c5 simultaneously; Also can open water pump a3 and water pump c5 simultaneously, perhaps just open water pump c5, satisfy the demand of Various Seasonal, different regions.As open water pump a3, water pump b4 and water pump c5 simultaneously and can realize the dew point cool effect, the demanding occasion that is adapted at lowering the temperature is used; Open the cooling-down effect that water pump a3 and water pump c5 can realize general tube type indirect evaporative cooler simultaneously; Only opening water pump c5, promptly is direct evaporative cooler, can lower the temperature, and also can realize humidification in the winter time.Therefore, see that each functional section water system is separately controlled separately from whole water circuit system.
The operation principle of the utility model devaporizer is,
The secondary-air passage that outdoor new wind directly gets into the precooling zone of the utility model heat exchanger tube a2 through filter 1.Auxiliary air and water carry out the wet exchange of heat, and temperature reduces but absorbs primary air side heat simultaneously, and discharges from precooling zone overfire air fan air outlet a18 through overfire air fan a16 rapidly, and primary air is got into cooling section by the precooling continued.This part air again some heat exchanger tube b21 primary air passage section gets out from the bottom after cooling section cooling; Having arrived secondary-air passage is in the wet channel; Flow from bottom to top along the auxiliary air runner then, carry out the wet exchange of heat with water, the air ' s wet bulb temperature in the secondary runner reduces; Cool off the primary air of remainder in the cooling section again; This part auxiliary air is discharged to outdoor from cooling section overfire air fan air outlet b19 through overfire air fan b17, finally warm eventually near dew-point temperature through direct evaporative cooling section cooling back, sends into conditioned area from pressure fan 20.At this moment, divide the part primary air temperature flow into the secondary passage lower,, thereby make wind pushing temperature near dew-point temperature so that the final wet-bulb temperature that exchanges with water of auxiliary air is near the primary air dew-point temperature.
