Abstract
The utility model relates to a heat-exchanger, belonging to the technical proposal of the improvement of a heat-exchanger structure in a compressed air drying device in the type of refrigeration. The utility model comprises a shell body, a heat exchange pipe and a flow guide plate, wherein, a hot-air inlet, a hot air outlet, a cold are inlet and a cold are outlet are respectively arranged on the shell body. The utility model is characterized in that the inner cavity of the shell body is provided with a shell pass partition board; the inner cavity of the end part of the shell body is provided with a pipe pass partition board. Inner and outer air of a heat exchange pipeline of the heat-exchanger are both two flow passes; the heat exchange efficiency can be increased; the heat load of the air entering the evaporator can be obviously reduced; the air output temperature can be conspicuously improved; the change of the whole shape of a device is small.
Description
The utility model belongs to the improvement technical scheme of heat exchanger in the frozen compressed air dryer.
Existing heat exchanger comprises housing, heat exchanger tube, deflector and is arranged on that hot-air on the housing is imported and exported, cold air is imported and exported.Hot-air carries out heat exchange from the cold air in shell side and the heat exchanger tube, and the pipe inner air and outer air is a flow process, and heat exchange is abundant inadequately, makes that the air thermic load that enters evaporimeter is big, has increased cooling load, and energy consumption increases, the dew point instability.The air that is come out by evaporimeter enters and can not get effective intensification in the heat exchanger simultaneously, makes outlet air temperature too low, the easy dewfall of escape pipe outer wall.
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, by the improvement of heat exchanging device structure, increases heat exchange process, provides a kind of result of use better heat exchanger.
Described a kind of heat exchanger comprises housing, heat exchanger tube, deflector, is respectively equipped with hot-air inlets, outlet on the housing, and inlet of cold air, outlet is characterized in that the housing inner chamber is provided with the shell side dividing plate, and the shell end inner chamber is provided with the tube side dividing plate.
This heat exchanger, simple and reasonable, the pipe inner air and outer air of heat exchange is two flow processs, has increased the heat exchange effect greatly, makes the air thermic load that enters evaporimeter obviously reduce, and air outlet temperature significantly improves, and the outfit of equipment profile variation is little.
Below in conjunction with Figure of description, the utility model is described in further detail, and provide embodiment.
Fig. 1 is the heat converter structure schematic diagram.
As shown in the figure, housing 2 inner chamber lateral arrangement heat exchanger tubes 3 are vertically arranged deflector 4, and housing 2 is provided with hot-air inlets 1 and outlet 8, inlet of cold air 7 and exports 5.Outlet 8 is used to connect the evaporimeter staving, and import 7 is used to connect evaporimeter staving or moisture trap outlet.Shell side dividing plate 9 is set in parallel between the heat exchanger tube 3, and the one group of heat exchanger tube 3 that is parallel to each other is divided into two groups up and down, and shell side dividing plate 9 right-hand members are kept somewhere port, makes hot-air flow into group shell side down from last group of shell side.Tube side dividing plate 6 is arranged on housing 2 right part inner chambers, makes from the cold air of import 7 inflows directly to discharge from exporting 5, and the upper and lower two groups of heat exchanger tubes 3 of must flowing through.During work, hot-air from import 1 inflow heat exchanger after up and down shell side enter the evaporimeter staving from exporting 8, after the freon heat exchange, air enters upper and lower two groups of heat exchanger tubes 3 through gas-water separation from import 7 and discharges from exporting 5, finishes heat exchange.
