Background technology
The tradition surface cooler is a heat exchange element of carrying out heat exchange for electronic heating equipment through refrigerant, is discharged to heat outdoor through refrigeration unit.The tradition surface cooler is single surface cooler structure; Single surface cooler shortcoming: 1, enthalpy difference is big in the process of single surface cooler processing air; When the air blow and return temperature difference increases; It is little that leaving air temp can become, and this is for the passive cooling that requires the higher computer equipment of humiture ratio of precision: the air blow and return excessive temperature differentials can cause the decline of Temperature and Humidity Control precision.2, when electronic heating equipment is in the bigger environment of air humidity, if wind pushing temperature is lower than air dew point, be prone to make air-supply band mist (water in air vapour condenses), this also can cause adverse effect to the passive cooling of computer equipment.
Summary of the invention
The object of the invention is exactly in order to overcome the defective that above-mentioned prior art exists a kind of good heat-transfer, stable to be provided, and the Xiang Buhui of the air after the cooling changes, and air-supply is not with the eclipsed form surface cooler heat exchanger of mist in the air cooling-down process.
The object of the invention can be realized through following technical scheme: a kind of eclipsed form surface cooler heat exchanger; It is characterized in that; This surface cooler heat exchanger comprises surface cooler heat exchanger framework, fin, backwater collector pipe, high temperature section water supply water distributor and low-temperature zone water supply water distributor; Described fin is arranged side by side in surface cooler heat exchanger framework; Be installed with water at low temperature water return pipeline vertical with fin and high-temperature water water return pipeline on this fin, the water inlet end of described water at low temperature water return pipeline is connected with the water side of low-temperature zone water supply water distributor, and the water side of water at low temperature water return pipeline is connected with a water inlet end of backwater collector pipe; The water inlet end of described high-temperature water water return pipeline is connected with the water side of high temperature section water supply water distributor, and the water side of high-temperature water water return pipeline is connected with another water inlet end of backwater collector pipe.
Described surface cooler heat exchanger framework front side is provided with front flow guiding plate, and surface cooler heat exchanger framework rear side is provided with the back baffler.
Described surface cooler heat exchanger frame left is provided with the differential pressure pickup mounting panel.
Be equipped with temperature sensor on described backwater collector pipe, high temperature section water supply water distributor, the low-temperature zone water supply water distributor.
Be equipped with electric control valve on described high temperature section water supply water distributor, the low-temperature zone water supply water distributor.
The water inlet end of described high temperature section water supply water distributor, low-temperature zone water supply water distributor is equipped with the loose joint of water supply double-bellmouth.
The water side of described backwater collector pipe is provided with backwater internal thread valve.
Compared with prior art, the present invention has the following advantages:
1, the contact-making surface of fin and water at low temperature water return pipeline and high-temperature water water return pipeline is big and tight, because the present invention is an overlay structure, heat transfer property is good and stablely can realize the secondary cooling, and then has improved the temperature difference of return air and air-out.
2, single air autonomous channel, air is little through resistance, and refrigerant or chilled water flow are when this installs; Cold is passed to through the air between fin through fin; Play the effect of cooling air, because the present invention is an overlay structure, enthalpy difference is little in the overall process of processing air; Under the monitoring of temperature sensor, can automatically adjust to the chilled water water yield in real time; And then the Xiang Buhui of humid air is changed, mist (water in air vapour condenses) is not with in air-supply in the air cooling-down process, helps the passive cooling of computer equipment.
