[0048] Refer to Figures 1 to 6 A further description will be made on an embodiment of a shell-and-tube heat exchanger with a dehumidification function of the present utility model.

[0049] A shell-and-tube heat exchanger with a dehumidification function includes a housing 7 and a cavity header 8, and further includes:

[0050] Refer to Figure 3 And Figure 4 , as a preferred embodiment, a partitioning mechanism is disposed on the housing 7 and the cavity header 8 for partitioning the cold fluid and the hot fluid. The partitioning mechanism includes:

[0051] A partition plate 10 is disposed on the cavity header 8 and fixedly connected to the cavity header 8;

[0052] A tube sheet 11 is disposed on the housing 7 and fixedly connected to the housing 7;

[0053] A baffle plate 13 is fixedly disposed on the housing 7.

[0054] When the device is working, the partition plate 10 separates the cold fluid and the cold fluid after heat replacement up and down. The tube sheet 11 is used to connect the conduit 12 to separate the inside of the cavity header 8 and the shell 7. A plurality of baffle plates 13 are provided and fixedly connected to the conduit 12. The baffle plates 13 are used to increase the turbulence of the hot fluid and improve the heat transfer efficiency.

[0055] Reference Figure 3 、 Figure 5 and Figure 6 , as a preferred embodiment, a dehumidification mechanism is provided on the cavity header 8 for dehumidifying the cold fluid. The dehumidification mechanism includes:

[0056] An automatic telescopic rod 14, fixedly connected to the cavity header 8;

[0057] An extrusion plate 15, provided on the automatic telescopic rod 14 and fixedly connected to the automatic telescopic rod 14;

[0058] A card slot 16, provided on the cavity header 8 and fixedly connected to the cavity header 8;

[0059] A water leakage port 19, provided on the card slot 16 and fixedly connected to the card slot 16 for draining the water adsorbed by the filter sponge 17;

[0060] A filter sponge 17, fixed on the card slot 16;

[0061] When the device is working, the moisture in the cold fluid is adsorbed on the filter sponge 17. After the heat replacement is completed, the automatic telescopic rod 14 pushes the extrusion plate 15 to slide, and the extrusion plate 15 applies pressure to the filter sponge 17 to squeeze out the moisture adsorbed on the filter sponge 17.

[0062] Reference Figure 1 、 Figure 2 and Figure 3 , as a preferred embodiment, a pipe orifice assembly is provided on the shell 7 and the cavity header 8 for discharging the fluid. The pipe orifice assembly includes:

[0063] A cold fluid inlet 1, fixedly connected to the cavity header 8;

[0064] A cold fluid outlet 3, provided on the cavity header 8 and fixedly connected to the cavity header 8;

[0065] A hot fluid inlet 4, fixedly connected to the shell 7;

[0066] A hot fluid outlet 5, provided on the shell 7 and fixedly connected to the shell 7;

[0067] The conduit 12 is fixedly arranged on the tube sheet 11.

[0068] Reference Figure 2 、Figure 4 and Figure 5 , as a preferred embodiment, the auxiliary components are fixedly arranged on the housing 7 and the cavity header 8, and the auxiliary components include:

[0069] The drain port 2 is fixedly connected to the cavity header 8;

[0070] The bolt 9 is fixed on the cavity header 8;

[0071] The round holes 18 are arranged on the pressing plate 15 and the clamping groove 16;

[0072] The bracket 6 is arranged on the housing 7 and fixedly connected to the housing 7.

[0073] It should be noted that a plurality of round holes are provided on the pressing plate 15 and the clamping groove 16 for the transmission of the cold fluid.

[0074] When the device works, the heat exchange between the hot and cold fluids is well realized through the mutual cooperation of the separation mechanism, the dehumidification mechanism, the pipe orifice assembly and the auxiliary assembly. The dehumidification mechanism can extrude the water from the water-absorbed filter sponge 17 and discharge it through the drain port 2, removing the damage caused by the moisture to the conduit 12 and also improving the service life of the filter sponge 17.

[0075] Working principle: When working, the cold fluid enters the cavity header 8 through the cold fluid inlet 1, and the hot fluid enters the interior of the housing 7 through the hot fluid inlet 4 on the housing 7. The cold fluid passes through the pressing plate 15, passes through the round holes 18, contacts the filter sponge 17, and the moisture in the cold fluid is adsorbed on the filter sponge 17. The cold fluid passes through the clamping groove 16 and enters the lower conduit 12 fixedly connected to the tube sheet 11, and is transported to the other cavity header 8 through the conduit 12. When the cold fluid accumulates in the cavity, it starts to enter the upper conduit 12. Under the combined action of the housing 7 and the baffle 13 on the housing 7, the hot fluid turns over the baffle 13 up and down inside the housing 7, increasing the degree of turbulence and the heat transfer area. The hot fluid contacts the conduit 12 and transfers the heat to the cold fluid in the conduit 12 to achieve heat exchange. The hot fluid is discharged through the hot fluid outlet 5, and the cold fluid is discharged through the cold fluid outlet 3. After the heat replacement is completed, the automatic telescopic rod 14 pushes the pressing plate 15 to slide, and the pressing plate 15 applies pressure to the filter sponge 17 to squeeze out the moisture adsorbed on the filter sponge 17, which flows to the water leakage port 19 and is discharged through the drain port 2, and the work is completed.

[0076] The above description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
