Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dehumidifying device used to reduce the humidity of a room by applying a refrigerating cycle and thereby to dry articles. Related to the improvement of.

[Conventional technology]

FIG. 3 shows a refrigerant circuit of the dehumidifying device. FIG. 4 is a diagram showing a cooler.

In FIG. 3, (1) is a compressor, (2) is a condenser,
(3) blower, (4) throttle device, (5) cooler,
(6) shows a refrigerant pipe connecting these respective devices. In FIG. 4, (7) is a heat transfer tube, (8) is a U vent, and (9) is a fin.

Next, the operation will be described. The high-pressure and high-temperature gas refrigerant discharged from the compressor (1) is supplied to the condenser (2) and forcedly cooled by the blower (3) to become a high-pressure and high-temperature liquid refrigerant, which is decompressed by the expansion device (4). Then, it becomes a low-pressure low-temperature gas-liquid mixed two-phase refrigerant which is sent to the cooler (5) and exchanges heat with the air flowing into the cooler (5). Incoming air is
After being cooled and dehumidified by heat exchange with the cooler (5), it is reheated by the condenser (2) and slightly heated by the inflowing air and blown out.

The cooler (5) is a heat transfer tube while the low-pressure low-temperature gas-liquid mixed two-phase refrigerant decompressed by the expansion device (4) flows through the heat transfer tube (7) and the U vent (8) to be evaporated. Heat is exchanged with the inflowing air through the fins (9) orthogonal to (7).
As shown in the drawing of the cooler in FIG. 4, it is composed of a plurality of paths with one path from the refrigerant inlet to the refrigerant outlet. still,
When the inflowing air is cooled and dehumidified by heat exchange with the cooler (5), it adheres to the surfaces of the fins (9) as condensed water, and the condensed water that has adhered falls down along the fins (9). To do.
Further, in the vicinity of the refrigerant outlet of each path of the cooler (5), the refrigerant is superheated steam, and the superheated steam that has left the cooler (5) is sucked into the compressor (1).

[Problems to be solved by the device]

Since the conventional dehumidifier is configured as described above,
While the inflowing air is cooled and dehumidified by heat exchange with the cooler, the condensed water adhering to the fin surface drops along the fins, and the near-refrigerant outlets of each path are overheated steam, causing condensation. There was a problem that the water was re-evaporated and the dehumidifying ability was lowered.

This invention was made in order to solve the above problems, and when the inflowing air is cooled and dehumidified by heat exchange with the cooler, the condensed water adhering to the fin surface drops along the fin. The purpose of the present invention is to prevent re-evaporation during that time and to improve the dehumidification capacity of the dehumidifier.

[Means for Solving the Problems]

The dehumidifying device according to the present invention is a cooler in which a fin portion located above the superheated steam region for each pass of the heat transfer tube along the flow of air flowing into the cooler is provided with a diagonally inclined cut-and-raised portion. It is equipped with.

[Action]

In the dehumidifier according to the present invention, the fins located at the upper part of the superheated steam region are provided with slanting cut-and-raised parts on the fin surface for each pass of the heat transfer tube along the flow of the air flowing into the cooler. When the attached condensed water drops along the fins, the condensed water once drops to the cut-and-raised parts of the fins and can drop to the lower side of the cooler without coming into contact with the superheated steam region.

〔Example〕

 An embodiment of this invention will be described with reference to the drawings.

FIG. 1 is a diagram of a cooler showing an embodiment of the present invention. FIG. 2 is a detailed view showing the fin portion of this cooler.

In FIG. 1, (5) is a cooler, (7) is a heat transfer tube,
(8) shows a U vent, (9) shows a fin, and (10) shows a cut and raised portion of the fin.

In FIG. 2, (9) is a fin, and (10) is a cut and raised portion of the fin.

Next, the operation will be described. The operation on the refrigerant cycle is the same as in the prior art, but as shown in the diagram of the cooler in FIG. 1, the inflowing air is cooled by the heat exchange with the cooler (5) and the fins (9 Condensed water adheres to the surface of) and adheres, and the condensed water drops along the fins (9), but is oblique to the fins located above the superheated steam region for each pass of the cooler (5). Since the cut-and-raised part (10) that slopes is attached to the condensate, the condensed water can drop to the cut-and-raised part (10) once and fall to the lower part of the cooler (5) without contacting the superheated steam region. .

[Effect of device]

As described above, according to the present invention, for each path of the heat transfer tube that constitutes the cooler along the flow of the air flowing into the cooler,
Since the fins located at the upper part of the superheated steam area are provided with a slanted cut-and-raised part, the condensed water adhering to the fin surface does not contact the superheated steam area and re-evaporation of condensed water can be prevented. In addition to this, the dehumidifying ability of the dehumidifying device can be improved.
