Description

[Detailed explanation of the invention] [Industrial application field] This invention is used in air conditioners such as fan convectors,
In particular, the present invention relates to improvements in the Finch-Eube type heat exchanger used therein.

[Prior Art] Fig. 4 is a side view showing a conventional heat exchanger disclosed in, for example, Japanese Utility Model Publication No. 60-41465. A plurality of fins made of aluminum plates are arranged in parallel on this tube at predetermined intervals.

The conventional heat exchanger is constructed as described above, and by passing hot water, for example, through the tube 1, the heat is transferred from the tube 1 to the fins 2, and is transferred between the fins by a blower (not shown). By blowing the air, heat is exchanged and hot air is blown out, heating the room.

[Problems to be solved by the invention] In the conventional heat exchanger as described above, the air blown by the blower flows from one side of the heat exchanger to the other side, so the hot air is not blown out. In the case of multiple directions, it is necessary to provide a separating plate on the air conditioner main body, which poses the problem of not only making the air conditioner larger but also making it more expensive.

This invention was made to solve this problem, and the purpose is to improve the heat exchanger so that the blowing direction can be separated without installing a separating plate in the air conditioner. be.

[Means for solving the problem] The air conditioner according to this invention has an air blower and a heat exchanger inside, and indoor air blown from the top is blown out from the front and bottom surface of the bottom through the heat exchanger. The heat exchanger includes a tube through which a medium passes, a plurality of fins arranged in parallel at predetermined intervals in this tube, and a front end extending downward from the center of the fins. The air guide is cut and bent, and is formed with a height such that it comes into contact with an adjacent fin.

[Function] In this invention, the air blown by the blower can be separated by the air guide and blown out in multiple directions.

[Example] Fig. 1 and Fig. 2 are a perspective view and a perspective view of a fin showing an embodiment of this invention, and Fig. 3 is a side view showing an air conditioner incorporating a heat exchanger according to this invention. It is a diagram. In the figure, reference numeral 11 denotes a tube, which is formed in series with each end connected by a U-shaped tube 12. Reference numeral 13 denotes a plurality of fins arranged in parallel at predetermined intervals on this tube, which are cut and bent with a predetermined curvature from the center to the side ends, and have a height such that they abut on adjacent fins 13. A shaped air guide 14 is provided. 15 is the casing of the air conditioner, 16 is the blade casing 1
7 is a blower consisting of blades 18 and an electric motor (not shown), and the arrows indicate the flow of wind.

The heat exchanger configured as described above has a blower 16
As shown in FIG. 3, indoor air is blown from the upper front surface of the casing 15 to the suction heat exchanger. This blown air is heat exchanged by a heat exchanger, and the air guide 14
As a result, part of the air is blown out from the lower front surface of the casing 15, and the other part is blown out from the lower surface of the casing 15, and the heat-exchanged air is blown out in two directions, forward and downward, without providing a separation plate or the like on the casing 15. be able to.

[Effects of the invention] As explained above, this invention is a casing for an air conditioner that has a blower and a heat exchanger inside and blows indoor air blown in from the upper part through the heat exchanger and out from the front and bottom surface of the lower part. , the heat exchanger includes a tube through which a medium passes, and a plurality of fins arranged in parallel at a predetermined interval in the tube;
The air guide is cut and bent from the center of the fin toward the bottom of the front end and has a height that abuts the adjacent fin, thereby separating the air flow using a heat exchanger. This makes it possible to blow air in multiple directions, eliminates the need to provide an air separation plate in the air conditioner as in the past, and has the effect of making the main body smaller.

FIG. 4 is a side view showing a conventional heat exchanger. In addition, the same reference numerals in each figure indicate the same parts, and 11
13 is a tube, 13 is a fin, and 14 is an air guide.

Claims (1)
