効率の向上を計らんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger used in refrigeration equipment such as refrigerators and air conditioners, and in particular in heat exchangers composed of fins and tubes, improving the heat exchange efficiency by improving the fins. The aim is to improve the

合うよう構成したものである。However, these methods are intended to improve the heat exchange efficiency mainly through the fins by creating turbulence in the wind flow on the fin surface or increasing the area of contact with the wind. However, heat transfer in a fin-tube heat exchanger is transmitted from the tube to the fins, and heat transfer between the fins and the wind alone is insufficient. The present invention is based on this viewpoint and is constructed so that the wind, the fins, and the tubes can efficiently communicate with each other.

In the figure, reference numeral 1 indicates a fin-tube type heat exchanger main body, which includes left and right end plates 2 and 3, and a large number of holes arranged in parallel and at equal intervals between the end plates 2 and 3. It consists of plate fins 4, 4, . . . and refrigerant tubes 5, 5, which are inserted orthogonally through the plates 2, 3, 4, 4, .

A chevron-shaped cut-and-raised portion 6 is formed by pressing ``, 5'', 5C'', etc. That is, this cut and raised portion 6 has an opening 7 in the row direction only on the windward side, and the pair of guide pieces 8 and 78 are inclined toward the leeward side from this opening 7.
and converge, and the converged tip 9 connects adjacent tubes in the row direction (for example, tubes 5a and 5b).
, 5c, the refrigerant tubes in the column direction adjacent to 5c are 5a',
5b', 5c') towards the center. Reference numeral 10 denotes a flange that holds the refrigerant tubes 5, 5 and is raised in the same direction as the protruding direction of the cut and raised portions 6.

After that, the flow enters through the opening 7 of the cut and raised portion 6 and flows on the other surface (indicated by the broken line arrow in the figure).
The inclined guide pieces 8, 8 converge at the tips and collide with the center of the refrigerant tube 5a''.

て効率の大なる熱交換器を得ることができる。On the other hand, since the flange 10 is not present here, the refrigerant flows directly while exchanging heat with the refrigerant tubes 5a''''. This action is performed in each of the adjacent cut and raised portions 6 and refrigerant tubes 5,
In addition, due to the turbulent flow effect caused by the cut and raised portions 6, the effect of wind flow is exerted on each of the plate fins 4, 4, . . ., refrigerant tubes 5, 5, . There are things that can be done to improve. As is clear from the above description, the heat exchanger according to the present invention consists of a large number of plate fins 2 arranged in parallel and tubes inserted through the plate fins, and the tubes are arranged in a staggered manner with respect to the flow direction of the wind. The tubes are arranged in a shape, and a chevron-shaped cut-and-raised part is formed between the tubes in the row direction, opening only in the row direction on the windward side and converging toward the center of the tubes in the other row directions on the leeward side. Therefore, the cut and raised parts create turbulent flow on the plate fin surface, and as a result, the flowing wind is converged and collides with the tube, which improves the heat exchange rate with the tube, improving overall efficiency. A large heat exchanger can be obtained.
