この発明は、熱交換装置を改良した冷却装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device that is an improved heat exchange device.
まず、従来の冷却装置について説明する。第１図〜第５
図に示すように、本体ｌの台枠２の所定の位置に冷凍回
路の圧縮機３と、液溜４と、一定間隔「α」で配設した
多数枚のフィン６、これらのフィン６を貫通する銅管７
および出入口管８から構成されている厚さ方向寸法が一
定のプレートフインチー−ブ式熱交換器９とが取り付け
られ、熱交換器室Ａと機械室Ｂを仕切るために下仕切板
ＩＯおよび上仕切板１１が取り付けられている。First, a conventional cooling device will be explained. Figures 1 to 5
As shown in the figure, a compressor 3 of a refrigeration circuit, a liquid reservoir 4, a large number of fins 6 arranged at regular intervals "α", and these fins 6 are placed at predetermined positions on the underframe 2 of the main body l. Penetrating copper pipe 7
A plate fin-chive type heat exchanger 9 having a constant thickness direction dimension and consisting of an inlet/outlet pipe 8 is attached, and a lower partition plate IO and an upper A partition plate 11 is attached.
また、本体ｌの上部に熱交換器用送風機１２が送風機取
付足１３を介して固定され、熱交換器９の吸込面を除く
面にそれぞれ左パネル１４、右パネル１５、前パネル１
６およびファンカバー１７が取り付けられている。In addition, a heat exchanger blower 12 is fixed to the upper part of the main body l via a blower mounting foot 13, and a left panel 14, a right panel 15, and a front panel 1 are respectively attached to the surface of the heat exchanger 9 other than the suction surface.
6 and a fan cover 17 are attached.
このような構成の冷却装置では、通常運転時に送風機１
２が運転されると、熱交換器９の上部すなわち送風機１
２に近い側が熱交換器９を通過する空気の流路抵抗が小
さいため、通過する空気量が多くなり、第３図中の矢印
Ｃのような風速分布となり、上部の方では熱交換能力が
大きく、下部になるに従って熱交換能力が小さくなるば
かりでな（、上部の方では異常に風速が大きくなるため
、熱交換器９のフィン６での風切り音が大きくなり、騒
音が高くなるという欠点があった。In a cooling system with such a configuration, the blower 1 is turned off during normal operation.
2 is operated, the upper part of the heat exchanger 9, that is, the blower 1
Since the flow path resistance of the air passing through the heat exchanger 9 is small on the side closer to 2, the amount of air passing through increases, resulting in a wind speed distribution as shown by arrow C in Fig. 3, and the heat exchange capacity is lower on the upper side. The disadvantage is that the heat exchange capacity decreases as you move toward the bottom (the wind speed becomes abnormally high at the top, so the wind noise from the fins 6 of the heat exchanger 9 becomes louder, resulting in higher noise). was there.
この発明は、送風機から近い側にフィン間隔の狭い熱交
換器を設置し、遠い側にフィン間隔が広い熱交換器を設
置することにより、上記従来のものの欠点を除去した冷
却装置を提供することを目的としている。The present invention provides a cooling device that eliminates the drawbacks of the conventional device by installing a heat exchanger with narrow fin spacing on the side closer to the blower and installing a heat exchanger with wide fin spacing on the far side. It is an object.
以下、この発明の一実施例を図面によって説明する。An embodiment of the present invention will be described below with reference to the drawings.
第６図および第７図に示すように、熱交換器９を上下に
分割し、フィン６の間隔を上部熱交換器はα−ａ、下部
熱交換器９ｂはα＋ａとなるように形成する。その他の
構成は、上述した従来のものと同様であるので、その説
明は省略する。As shown in FIGS. 6 and 7, the heat exchanger 9 is divided into upper and lower parts, and the spacing between the fins 6 is set to α-a for the upper heat exchanger and α+a for the lower heat exchanger 9b. The other configurations are the same as those of the prior art described above, so the explanation thereof will be omitted.
この実施例では、上述したように、上部の熱交換器９ａ
の方が下部の熱交換器９ｂよりフィン間隔が狭く形成さ
れているため、流路抵抗が大きくなり、通過する空気量
が第６図中の矢印りのように従来より均一化され、熱交
換能力を有効に利用でき、風速も均一になることにより
、風切り音が低下し、低騒音化することができる。In this embodiment, as described above, the upper heat exchanger 9a
Since the fin spacing of the lower heat exchanger 9b is narrower than that of the lower heat exchanger 9b, the flow path resistance becomes larger, and the amount of air passing through is made more uniform than before as shown by the arrow in Fig. 6, which improves heat exchange. Since the capacity can be used effectively and the wind speed is uniform, wind noise can be reduced and noise can be reduced.
また、他の実施例として、第８図および第９図に示すよ
うに熱交換器の上下分割個数を増加することにより、更
に流路抵抗が均一化でき、空気量が均一化されて、上述
した第６図および第７図に示すものと同等以上の効果が
得られる。In addition, as another example, by increasing the number of upper and lower divisions of the heat exchanger as shown in FIGS. Effects equivalent to or better than those shown in FIGS. 6 and 7 can be obtained.
以上説明したように、この発明は、本体に設けた送風機
によって通風される熱交換器を複数に分割し、送風機に
近い側と遠い側の熱交換器のフィン間隔を変えることに
より、熱交換器を通過する空気量が均一化されるように
したので、熱交換器の能力を有効に利用でき、風切り音
を低くし、低騒音化することができるなどの優れた実用
的効果を有するものである。As explained above, this invention divides the heat exchanger that is ventilated by the blower provided in the main body into a plurality of parts, and changes the fin spacing of the heat exchanger on the side near and far from the blower. Since the amount of air passing through the heat exchanger is made uniform, the capacity of the heat exchanger can be used effectively, and it has excellent practical effects such as reducing wind noise and noise. be.
