Heat-Pipe Heat Exchanger - MB Electronic

1 Heat-Pipe HeatExchangerHeat pipe heat Exchanger For air-air1 heat pipe heat ExchangerHeat Exchanger , which transfers the heat from one medium to another, is the most commonthermal equipment in various of industry sectors. It s widely used in chemical, energy,machinery, transportation, refrigeration, air conditioning and aerospace fields. Apart fromassuring the certain technological processes and necessary conditions, heat Exchanger alsoprovides solutions to the heat recovery and energy conservation of the industry a kind of heat Exchanger , heat pipe heat Exchanger (HP heat Exchanger ) often has arectangular shell with many finned heat pipes mounted inside. In the middle of the shell,there is a diaphragm, which partitions the shell into two channels, high-temperature fluidchannel and low-temperature fluid channel.

2 When the two flows pass through theirrespective channels simultaneously, the heat energy is transferred from the high-temperature fluid to the low one by the heat pipes. Because of its simple structure, highheat exchanging efficiency and low pressure loss, HP heat Exchanger has won a good gracesand extensive market of many HP heat Exchanger For air-airBased on the requirements of our customers, WTL has been successfully researching anddeveloping lots of HP heat exchangers for air-air, which are proved to be reliable andefficient in application. From these practices, we ve accumulated many valuableexperiences, especially the cooling system for sealed electrical equipment. It is extremelydetrimental to the operation of the electrical equipment and instruments in many workingconditions where the air contains much dust, moisture and other corrosive medium.

3 On onehand, the abominable environment will seriously affect the normal use of the equipment,shorten the service life and even lead to high failure rate; on the other hand, Sealing thewhole equipment in a cabinet can protect the equipment from the damage of the harshenvironment, however, the risk of heat dissipation in sealed system becomes anotherannoyance and the equipment failure due to over-temperature is also a hard problem. As tothis case, we have specially developed a new type of HP heat Exchanger to effectively solvethe heat dissipation of the sealed electrical equipment pipe heat Exchanger For Traction Convertor In CRH(ChinaRailway High-Speed)(1)Product Exhibition(2)Product ParameterFeatures1.

It is usually achieved by preheating the combustion air andturning the low value thermal energy in the flue gas to the high value thermal energy incombustion chamber.)

6 Traditional tubular preheater is usually big in volume, big inpressuredrop,prone to corrosion and easy to have the problem of ash clogging. Ourcompany has designed and manufactured heat pipe air preheater to ease the aboveproblems. The heat pipe air preheater has been used successfully in the preheater and boilerin the industries of petroleum, chemical,metallurgy, construction materials, electricitygeneration, etc. with significant energy ,Product StructureThe heat Exchanger is consisted of casing, heat transfer bundle, the partitions of cold andhot sides, and the middle partition. The casing is divided into two regions by the middlepartition, namely the cold stream passage and the hot stream passage. The heat transferbundle is fixed on these three partitions.

7 The heat transfer bundle located in the hot streampassage is the hot end while the heat pipe bundle in the cold stream passage is the cold hot stream is the flue gas and the cold stream is the fresh ,Product is possible to adjust the surface temperature of the heat transfer component bychanging the ratio of the hot end area to the cold end area of the heat transfer the surface temperature is higher than the acid dew point of the flue gas, it couldavoid low temperature acid corrosion. In comparison with tubular air preheater, thesurface temperature will be higher at the same flue gas temperature. Thus it wouldreduce the low temperature acid corrosion. At the same surface temperature, it wouldreduce the temperature of flue gas and increase the thermal efficiency of the reheaterand it be impossible to avoid low temperature acid corrosion, anti-corrosionmaterial could be used on the passage, which is subject to acid corrosion.

8 Anti-corrosion surface treatment or enamel could be used to reduce the low temperatureacid corrosion. When enamel is used, the heat transfer surface would be smooth withthe additional advantage of reducing ash accumulation and easy the Exchanger , the flange and sealing materials used in the middle partition wouldprovide effective sealing with minimum leaking between the hot stream and of the cold stream and hot stream transfer heat on the fin welded on the heatpipe. The Exchanger has a compact structure and is Exchanger would be used in counter flows increasing the thermal of the cold and hot streams are single pass with less flow heat transfer component could be dismantled for easy inspection heat transfer component could be placed vertically or with an inclination anglebetween 5 and 10 degree with the cold end above the hot Exchanger1 Product Exhibition2,Product StructureThe Exchanger is consisted of casing, heat transfer bundle, hot and cold side partition, andthe middle partition.

9 The casing is divided into two zones by the middle partition to form thecold stream passage and hot stream passage. The outdoor fresh air and indoor exhausted airgo through the passages and exchange heat in counter ,Product DescriptionProducts can be divided into two categories according to to the poor housing air quality,it be added to the fresh air heat , the outdoor fresh air has higher temperature than the indoor exhausted heat transfer bundle lowers the temperature of the outdoor fresh air and reducesthe air conditioning cost. In winter, the outdoor fresh air has lower temperature thanthe indoor exhausted air. The heat transfer bundle then preheats the outdoor fresh airand saves the cost of space heating. Thus it can recover the heat energy from theindoor exhausted air, save the energy cost and maintain the air without fresh air exchange housing, just need the heat Exchanger whichcan release the heat to the environment.

10 There are so many communications andelectronic equipment in the unmanned communication station. They should be stayedin a relatively low and stable temperature and humidity. The air-condition should beworked all year around,because they will release big heat to the environment. The air-condition will be wasted a lot of electricity. Our heat exchangers can release the heatto the outside when the temperature of the outside is lower than the insidetemperature. Such as in winter,spring and autumn, our air Exchanger can reduce thefrequency and duration of air-condition.
