Description of drawings
Characteristics of the present invention and advantage will display in the following description by example and with reference to accompanying drawing, wherein:
-accompanying drawing 1 is the longitdinal cross-section diagram of plate type heat exchanger of the present invention; And
-accompanying drawing 2 is cross-sectional views of 2-2 line in Fig. 1.
The specific embodiment
Accompanying drawing 1 has provided a plate type heat exchanger, its integral body is marked as numeral 1 and it comprises, on the one hand, a for example vertically disposed elongated closed chamber 2, and on the other hand, comprise a plate bundle 3 that is positioned at described closed chamber 2, plate bundle 3 provides a free space 4 around described plate bundle with closed chamber 2.
Profile is the plate bundle 3 that has parallel pipe substantially, comprises a folded plate (not marking) that is parallel to each other, and the two kinds of independences and a mobile double loop A and the B of providing of the fluid of adverse current for example are provided between plate.
Heat exchanger 1 also comprises the feed pipe 10 of hot fluid, this feed pipe is also referred to as current collector by a connector 11 and directly is connected with the inlet A1 of the first loop A of plate bundle 3, also comprise one in addition in case flow into the discharge nozzle 12 of the fluid that above-mentioned plate bundle 3 just has been cooled, this discharge nozzle directly is connected with the outlet A2 of the described first loop A by a connector 13.In the embodiment shown in the drawings, hot fluid flows into plate bundle 3 downwards.
The feed pipe 20 that also comprises a cold fluid in the heat exchanger 1, this feed pipe is connected with the inlet B1 in plate bundle second loop with free space 4 between the closed chamber 2 by plate bundle 3.
The inlet B1 of the second loop B is away from the inlet A1 of the first loop A of plate bundle 3.
At last, heat exchanger 1 also comprises one in case the discharge nozzle 21 of the fluid that the second loop B that flows into plate bundle 3 just has been heated, and this discharge nozzle is connected by the outlet B2 of a connector 22 with this second loop B.Therefore cold fluid slave plate bundle 3 is to the upper reaches.
As shown in Figure 1, the feed pipe 10 of hot fluid, the discharge nozzle 21 of the feed pipe 20 of cold fluid and the fluid that has been heated all are arranged in the zone of same end of closed chamber 2, are positioned at the upper end of this closed chamber 2 in embodiment shown in the drawings.
Plate type heat exchanger 1 comprises device 25, is used to guide cold fluid and flows between the inlet B1 of the second loop B of the feed pipe 20 of cold fluid and plate bundle 3 along closed chamber 2 inwalls.
As shown in Figure 1, the device that the guiding cold fluid flows comprises an inner casing 25, inner casing 25 comprises the first wall 26 that is arranged on loop A inlet A1 and loop B outlet B2 top, and is arranged in the free space 4 of closed chamber 2 between plate bundle 3 and provides second wall 27 of an annular channel 5 for described cold fluid with closed chamber 2 inwalls.
In the embodiment shown in the accompanying drawing 1, first wall 26 is planes.In order to help cold fluid to flow into annular channel 5, wall 26 also can be other shape, for example hemispherical or taper.
Because inner casing 25 expect when cold fluid between the inlet B1 of the pipe 20 and the second loop B of plate bundle 3, cold fluid is along the inwall inflow annular channel 5 of closed chamber 2, and cooled off closed chamber 2 thus.The wall 27 of inner casing 25 extends in a part of length range of plate bundle 3, flows into looped pipeline 5 with the control cold fluid, and towards the direction stream of the inlet B1 of the second loop B of plate bundle 3, shown in arrow F among Fig. 1.
Inner casing 25 is supported, for example by wall 26 being welded on time material pipe 10 and the discharge nozzle 21.
Cold fluid is cooled along the mobile closed chamber 2 that makes of the inwall of closed chamber 2, and a plurality of shell (not shown) that help using same thickness join end to end and make closed chamber 2, therefore make these shells can link together and reduce the cost that this closed chamber is produced and made.
