Abstract
The utility model discloses a condensing heat exchanger used for clothes dryer which includes a plurality of overlapped rectangle tubular heat exchange units. The condensing heat exchanger used for clothes dryer is characterized in that the inner surface of a rectangle air duct is provided with small slots; the opening directions of the small slots are same with the flowing direction of water inside the rectangle air duct. In the condensing heat exchanger used for clothes dryer, a plurality of small slots are arranged in the inner walls of the rectangle ducts in the heat exchange units, which destroys water-condensed wall surface and quickens the condensing speed through the unevenness on the surface thereof; besides, the condensing heat exchanger used for clothes dryer leads the opening direction and the water flow directions to be consistent, is beneficial to taking way the water in the clothes of a rotary drum and discharging condensation water, enlarges the heat exchange area and improves the heat exchange effect.
Description
Technical field
The utility model relates to a kind of condensing heat exchanger, what be specifically related to is a kind of condensing heat exchanger that is applied on the air setting formula dryer.
Background technology
Air setting formula dryer is a kind ofly to utilize electrical heating as thermal source, and hot-air is blown to cylinder, carry out the wet exchange of heat with clothing after, damp-heat air discharge drum; In air setting formula dryer, hot humid air is introduced into condenser, and damp-heat air flows in pipe, and new air flows outside finned tube, and through after the heat exchange, the outer new air of pipe is heated, outside the temperature rising discharge machine; The hot humid air water outlet of condensing that is cooled in the pipe is along flowing out in the pipe.
In air setting formula dryer, circulate in the environment of humid air relative closure in system, so the heat exchange condensation efficiency of condensing heat exchanger has directly determined the complete machine efficiency.But rectangular duct 2 (as shown in Figure 2) in the heat exchange unit 1 in the existing air setting formula dryer, its inner wall smooth, the inboard area of the rectangular duct 2 by this structure is little, surfacing, unfavorable water is taken away moisture and the rapid condensation of water vapour and the discharge of condensate water in the cylinder clothing, thereby influences the performance and the heat exchange effect of dryer.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of increase drainage, quickens the discharge of condensed water, helps taking away the condensing heat exchanger that the dryer of the moisture in the cylinder clothing is used, and increases heat exchange area, improves the heat exchange effect.
To achieve these goals, the utility model is to realize by the following technical solutions:
The condensing heat exchanger that a kind of dryer is used, the heat exchange unit that comprises a plurality of rectangular tubular is stacked, described heat exchange unit is provided with rectangular duct, it is characterized in that, have sulculus at described rectangular duct inner surface, the fluting direction of described sulculus is identical with current direction direction in the rectangular duct, and described groove depth is 0.1～0.4 times of air channel wall thickness.The utility model is accelerated rate of set because the out-of-flatness on surface has destroyed the water wall that condenses; In addition, make the fluting direction consistent, help the discharge of condensate water with water (flow) direction.
The utility model utilizes the air-air condensing heat exchanger that hot humid air is carried out cooling and dehumidifying, and the cold dry air that dehumidified heats again, takes away the moisture in the cylinder clothing, and so circulation is with cloth drying.
Circular air channel is the rectangular tube passage, the damp-heat air moisture that freeze-outs that is cooled therein, and condensate water with the wind passage flows out; Cooling air flow is crossed fin between rectangular duct, carries out heat exchange by fin, tube wall and inner air tube.
The utility model makes its surperficial out-of-flatness by the rectangular duct inwall in the heat exchange unit is made a plurality of sulculuses, has destroyed the water wall that condenses, and accelerates rate of set; In addition, make the fluting direction consistent, help taking away the moisture in the cylinder clothing and the discharge of condensate water, increase heat exchange area, improve the heat exchange effect with water (flow) direction.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the rectangular duct structural representation of existing heat exchange unit.
Fig. 2 is a perspective view of the present utility model.
The structural representation of Fig. 3 heat exchange unit of the present utility model.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Fig. 5 is the workflow schematic diagram of an embodiment of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 2 to Fig. 4, the condensing heat exchanger 100 that a kind of dryer is used, the heat exchange unit 10 that comprises a plurality of rectangular tubular, sheet is stacked, described heat exchange unit 10 is provided with rectangular duct 11, have sulculus 12 at described rectangular duct 11 inner surfaces, described sulculus 12 careful being arranged on rectangular duct 11 inner surfaces make its inner surface out-of-flatness, destroy the water wall that condenses, accelerated rate of set.
In addition, described each sulculus 12 makes the interior water (flow) direction of fluting direction and rectangular duct consistent, helps the discharge of condensate water.
The groove depth of described sulculus 12 is 0.1～0.4 times of rectangular duct wall thickness, in the present embodiment, when groove depth be the air channel wall thickness 0.4 the time, area increases than being about 2.1: 1; If the degree of depth increases, area increases and can improve than also, but can influence the intensity of pipeline.
Referring to Fig. 1 and Fig. 5, operation principle of the present utility model is: the damp-heat air A that comes out from cylinder enters the rectangular duct 11 of condensing heat exchanger 100, cooling air C (from environment) passes through fin, the air channel wall carries out heat exchange with the hot humid air of the rectangular duct 11 of flowing through, the hot humid air air C that is cooled is cooled to below the dew point, separate out condensate water E, along rectangular duct along air flow, condensate water is discharged, air cooling-down falls wet (absolute moisture content), become dry air and discharge D and cold dry air B discharge, enter the systemic circulation air channel, after the process heater is heated as high temperature dry air F, send into cylinder, after carrying out the wet exchange of heat with wet wash, circulating air becomes hot humid air B and enters condensing heat exchanger 100 once more, so circulation, by the air-air condensing heat exchanger, realized the transfer of moisture.
The utility model makes its surperficial out-of-flatness by rectangular duct 11 inwalls in the heat exchange unit 10 are made a plurality of sulculuses 12, has destroyed the water wall that condenses, and accelerates rate of set; In addition, make the fluting direction consistent, help taking away the moisture in the cylinder clothing and the discharge of condensate water, increase heat exchange area, improve the heat exchange effect with water (flow) direction.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
