に関するものである。[Detailed description of the invention] The present invention provides a large number of slit grooves 3 at appropriate locations on a heat sink 1 formed by drilling a large number of heat sink tube insertion holes 2, and the entire periphery of the slit grooves 3. Alternatively, the present invention relates to a slit type heat exchanger characterized in that a protruding lid piece 5 of a slit groove 3 is provided with sawtooth-like uneven portions 4.
従来、第１図示の如く熱交換効率を良好とする
目的で放熱板１に多数のスリツト溝３…を穿孔し
てなる所謂スリツト式の熱交換器が知られている
が、斯かるスリツトフインの熱交率が良好である
のはリーデイングエツジの効果がきわめて大であ
るがためと謂われている。 Conventionally, a so-called slit-type heat exchanger is known in which a large number of slit grooves 3 are bored in a heat dissipation plate 1 for the purpose of improving heat exchange efficiency, as shown in the first figure. It is said that the reason why the crossing rate is good is that the effect of the leading edge is extremely large.
本考案は斯かるスリツトフインにおいて該スリ
ツト溝３の孔周全周縁に、或はスリツト溝３の突
出蓋片５に第２図、第３図示の如く鋸歯状の凹凸
型状４を形成したことによつてエツジ全長がきわ
めて大となり熱交換効率が非常に良好なる熱交換
器が簡単に求め得られるのである。 The present invention is achieved by forming a serrated concavo-convex pattern 4 on the entire circumference of the hole of the slit groove 3 in the slit fin, or on the protruding cover piece 5 of the slit groove 3, as shown in FIGS. 2 and 3. As a result, a heat exchanger with extremely large edge length and very good heat exchange efficiency can be easily obtained.
特に前記凹凸型状４部分の先端部が突出してい
るがために伝熱作用が頗ぶる良好となり、且つ板
面間に積極的に乱流を起成せしめて熱交換作用を
より確実良好に行なわしめることができ得る等の
効果を有するものである。 In particular, since the tips of the four concave-convex portions protrude, the heat transfer effect is extremely good, and turbulent flow is actively generated between the plate surfaces to more reliably and effectively perform the heat exchange effect. It has the effect of being able to tighten the area.

待することができ得ることは謂うまでもない。 As another embodiment of the present invention, as shown in the fourth figure, the slit groove 3 or the protruding lid piece 5 is formed into a shape in which sawtooth-like uneven portions 4' are bent vertically or horizontally alternately. Needless to say, we can expect the following effects.
