(three summary of the invention
At existing plate-fin heat exchanger, increased external pipeline between its evaporator section and the precooling zone, the weight of whole heat exchanger is big, cost is high, volume is also big and effective volume is less, and external pipeline is directly exposed in the outside air, very easily heat up from exporting the 6 cold dry air that come out because of the heat conduction of outside air, thereby can have influence on cooling to the hot humid air of precooling zone, the shortcoming that heat exchange efficiency is lower, the invention provides another plate-fin heat exchanger, it is in light weight, cost is lower, the useful space is big, heat exchange efficiency is higher.
Its technical scheme is such: it comprises shell and distribution precooling zone and evaporator section in the enclosure, described precooling zone and evaporator section comprise low-temperature receiver channel design and hot-air channel structure respectively, the hot-air channel structure of described precooling zone is connected with the hot-air channel structure of described evaporator section and communicates, separate by dividing plate between the low-temperature receiver channel design of described precooling zone and the low-temperature receiver channel design of described evaporator section, on described precooling zone, described shell is provided with air intlet, below described evaporator section, described shell is provided with discharge structure, it is characterized in that: described precooling zone and evaporator section are distributed in the upper lateral part in described enclosure space as a whole, the bottom in described enclosure space and a sidepiece are hollow, the air of described evaporator section enters precooling zone from the fin of the bottom back of coming out along the hollow part and from a side of precooling zone, the opposite side of corresponding described precooling zone, described shell are connected with the dry air outlet.
It is further characterized in that: described discharge structure comprises the stainless steel cloth dehydrater and is installed in water fender below the stainless steel cloth dehydrater that below described water fender, described shell is provided with discharge outlet; Described hot-air channel structure, low-temperature receiver channel design comprise passage respectively and are installed on the interior fin of passage, described passage is respectively to surround by the dividing plate of equal shape and with upper end, lower end or the left end of two dividing plates, the parting bead that right-hand member is tightly connected, described hot-air channel, low-temperature receiver passage interlayer distribute, and the passage of described hot-air channel and described low-temperature receiver passage flows to perpendicular; Described fin is a sawtooth pattern; Serrated fin in the described hot-air channel is vertically arranged; Serrated fin in the described low-temperature receiver passage is transversely arranged.
Among the said structure of the present invention, because the cold air that comes out from evaporator section portion in the enclosure directly enters precooling zone, omitted external pipeline like this, compact conformation, cost is low, the efficient of heat exchange is higher, and the vertical or horizontal arrangement of fin in hot-air channel and the low-temperature receiver passage, adopt in line like this, the fin of Shi Yonging will lack comparatively speaking, air is fast by flowing velocity wherein, higher heat exchanger effectiveness and lower cost have further been guaranteed, thereby avoided existing plate-fin heat exchanger, increased external pipeline between its evaporator section and the precooling zone, the weight of whole heat exchanger is bigger, the cost height, volume is also bigger, and effective volume is less, and external pipeline is directly exposed in the outside air, the cold dry air that exports out from evaporator section very easily heats up because of the heat conduction of outside air, thereby can have influence on the cooling to the hot humid air of precooling zone, the shortcoming that heat exchange efficiency is lower.
