Description

[Detailed Description of the Invention] The present invention relates to the structure of a heat exchanger for an air conditioner equipped with a dehumidification circuit.

In this type of air conditioner, a dehumidifying heat exchanger 1 and a reheating heat exchanger 2 are installed side by side with a required gap between them. For example, if the dehumidifying heat exchanger has two rows of refrigerant flow pipes and the reheating heat exchanger is arranged in one row, the dehumidifying heat exchanger 1 Although there is no elongation during assembly, elongation inevitably occurs in the single-row reheating heat exchanger 2, and when both are assembled integrally using side plates, the difference in dimensions due to the elongation causes warping, as shown in Figure 3. Similarly, the approximate center of the reheating heat exchanger 2 approaches the dehumidifying heat exchanger 1 by curving the dehumidifying heat exchanger 1, and in order to maintain the above-mentioned required gap, the side plates 3 are used to close both ends. I had to set the mounting position to d + △ in anticipation of warping.

On the other hand, in order to prevent this, there is a device in which the fins of the surface heat exchanger are integrated by making slits at positions corresponding to the gaps in the surface heat exchanger, but according to this structure, the surface heat is exchanged through the joints of the fins. This had the disadvantage that the device could be thermally short-circuited due to heat conduction, impairing its original function.

The present invention eliminates the above-mentioned drawbacks of the conventional type.The present invention will be explained with reference to an embodiment shown in the figure below.In Figure 1, 1 is a dehumidifying heat exchanger, 2 is a reheating heat exchanger; For example, the refrigerant flow pipes 5 of the heat exchanger have two rows of the former and one row of the latter.
The fins of each heat exchanger are formed separately.

When assembling the flowing refrigerant flow pipe 5 and fins 6, a large number of fins are arranged over the entire width, and a gap between the heat exchangers is maintained at a required position, for example, approximately in the middle. Therefore, a support plate 4 that mechanically links the surface heat exchanger is arranged parallel to the fins, and both sides are fixed with side plates 3.

In the above configuration, the support plate 4 is desirably made of a thermally nonconducting material, and by using, for example, the above-mentioned refrigerant flow pipe as a linking means for the surface heat exchanger, the two can be connected by linking the pipes.

Further, the support plate 4 may be large enough to reach both ends of the fin, or may be large enough to connect a part of the fin, and the number of supporting plates 4 may be one placed approximately in the middle of the overall width, Alternatively, a plurality of them may be equally distributed.

As explained above, the dehumidifying heat exchanger 1 and the reheating heat exchanger 2 are formed separately, but when assembling them, the required gaps are maintained at the required locations to mechanically connect them. By arranging the support plate 4, it is possible to eliminate the shrinkage of the gap in the surface heat exchanger due to warping, etc. in the conventional type, and it is possible to maintain the required gap d as a whole, thereby improving the individual functions of the heat exchanger. Can fully demonstrate.

Please note that this assembly process is no different from the conventional model.
It also has the effect of reducing the overall volume.
