Abstract

PURPOSE:To improve the heat changing efficiency by inserting a metallic sealing component in the notch of a heat exchanger so that the suction air may be prevented from passing through the notch almost without exchanging heat. CONSTITUTION:The air sucked from the front grill 6 exchanges heat in the heat exchanger 1 and is blown out through the fins 2 out of the blow out grill 4. Since a metallic sealing component 9 is inserted between the upper heat exchanger 1a and the lower heat exchanger 1b, the air sucked from the front grill 6 is prevented from passing through the notch between the upper heat exchanger 1a and the lower heat exchanger 1b almost without exchanging heat. In order to further improve the sealing, the upper and lower ends of the sealing component 9 are turned up. When the air conditioner is performing the cooling operation, water droplets 10 condensed on the front surface of the upper heat exchanger 1a will not drop out of the front surface of the upper heat exchanger 1a from the upper end of the notch. Instead, water droplets 10 are guided from the turned up part of the sealing component 9 to the heat transmission pipe 1d side of the upper heat exchanger 1a for processing the condensate.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a finned heat exchanger for an air conditioner.

Conventional technology Conventionally, as a heat exchanger with a curved part,
As described in Japanese Patent No. 118430, there is a heat exchanger in which a notch is provided on the surface facing the fin air outlet and a surface opposite to the surface, and the heat exchanger is bent based on the notch.

Problems to be Solved by the Invention However, in the above-mentioned conventional technology, there is a problem in that the air sucked in from the heat exchanger passes through the notches provided with the fins, and almost no heat exchange is performed.

Means for Solving the Problems In order to solve the above problems, the present invention has a structure in which a metallic sealing material is inserted into the notch of the fin of the heat exchanger.

Furthermore, in the heat exchanger, an upper end plate is attached to the right end and left end of the upper heat exchanger above the notch and has a fold at each lower end, and an upper end plate is attached to the right end and left end of the lower heat exchanger below the notch. The sealant is secured by lower end plates attached and having folds at each upper end.

action The effects of the above means are as follows.

In the present invention, by inserting a metallic sealing material into the notch of the heat exchanger, air sucked into the notch of the heat exchanger is prevented from passing through without substantially performing heat exchange.

Furthermore, the lower end of the upper end plate and the upper end of the lower end plate of the heat exchanger are each folded back, and a metal sealing material inserted into the notch of the heat exchanger is fixed. It is possible to keep the angle of the lower heat exchanger at a predetermined angle.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

First, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a side sectional view of the indoor unit, and FIG. 2 is an enlarged view of the bent portion of the heat exchanger.

In the figure, 1 is a heat exchanger, 2 is a fin, 3 is a water tray, 4 is a blow-off grill, 5 is an underframe, 6 is a front grill, 7 is a filter, and 8 is a vertical wind direction changing blade. Here, in the heat exchanger 1, the upper heat exchanger 1a and the lower heat exchanger 1b are bent at a predetermined position in the longitudinal direction of the fin IC, and the fin 1c is bent between the upper heat exchanger 1a and the lower heat exchanger 1b. heat exchange 1
Connects b. Air sucked in from the front grille 6 undergoes heat exchange by a heat exchanger l, and is blown out from the outlet grille 4 through the fins 2. At this time, by inserting a metallic sealing material 9 between the upper heat exchanger 1a and the lower heat exchanger lb, air sucked in from the front surface of the front grille 6 can pass through the notches of the upper heat exchanger 1a and the lower heat exchanger 1b. through which little heat exchange takes place. Furthermore, in order to strengthen the sealing performance, the upper and lower ends of the sealing material 9 are folded. In addition, when the air conditioner is in cooling operation, the sealing material 9 prevents water droplets 10 condensed on the front surface of the upper heat exchanger 1a from dripping from the upper end of the notch of the upper heat exchanger 1a to the front surface.
Introduce water droplets 10 into the heat exchanger tube ld side of the upper heat exchanger 1a from the folded part of 4! By treating condensed water and using a metallic material for the sealing material, we aimed to improve the heat exchange performance of the air sucked in through the notch.

Next, FIG. 3 is a perspective view of the bent portion of the heat exchanger 1.

In FIG. 3, 11 is a heat exchanger end plate. Here 1
Like the heat exchanger 1, the upper heat exchanger end plate 11a and the lower heat exchanger end plate 11b are fixed to the heat exchanger 1 so as to form an angle at a predetermined position in the longitudinal direction. ing. Furthermore, in order to maintain a predetermined angle, folds are provided at the lower end of the upper heat exchanger end plate 11a and the upper end of the lower heat exchanger tib, and the folds are applied to the folds having a predetermined angle provided at the right and left ends of the sealing material. composition.

Effects of the Invention As is clear from the above explanation, the present invention inserts a metallic sealing material into the notch of the heat exchanger, so almost no heat exchange takes place in the notch, preventing suction air from passing through and reducing heat. This contributes to increasing exchange efficiency.

Further, since the metallic sealing material has a predetermined angle and is fixed to the end plate of the heat exchanger, the heat exchanger can be held at a predetermined angle in the notch.

Furthermore, by folding the sealing material, it is possible to improve the sealing performance with the heat exchanger and to smoothly treat condensed water.
