本発明は、小型、高効率の熱交換器、特に薄型形状の熱
交換器に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a compact, highly efficient heat exchanger, particularly a thin-shaped heat exchanger.
従来のこの種のものとしては、第1図に示す如きものが
ある。すなわち、多数の細管1゛ と、この細管1′
の両端を支えているフランジ2°及び3° と、この細

、さらにフランジ3″に接し、他方の細管1”内の流路
の入口を有する配管部材8゛と、この流路の出口を有す

流体と細管1′の壁を介して熱交換し、配管部材9”の
出口に出る。他方の流体は、入口5″から入って細管1
′の外を通り、ここで一方の流体と細管1′の壁を介し
て熱交換し、出口6゛に出る。A conventional device of this type is shown in FIG. That is, a large number of thin tubes 1'' and this thin tube 1'
flanges 2° and 3° supporting both ends of the tube 1', a cylinder 4' surrounding this thin tube 1', this cylinder 4', and a flange 2'.
A baffle plate 7' which is sealed and divides the flow path formed by ' and 3', an inlet 5' and an outlet 6' of this flow path, and a baffle plate 7' that is in contact with the flange 3'' and inside the other capillary tube 1''. It consists of a piping member 8' having an inlet of a flow path and a piping member 9' having an outlet of this flow path. One fluid is pipe member 8'
The fluid enters from the inlet of the pipe 1', passes through the capillary tube 1', exchanges heat with the other fluid through the wall of the capillary tube 1', and exits the pipe member 9''.The other fluid enters the pipe from the inlet 5'' Enter the tubule 1
1', where it exchanges heat with the other fluid through the wall of the capillary tube 1', and exits at the outlet 6'.
このように従来の熱交換器においては、細管1°の管壁
を介して熱交換される為、細管1゛の内径と外径の比に
より伝熱面積比が決定し、伝熱面積比の選定の自由度が
少ない。一般に、製造上あまり細い細管を使用できず、
又細管相互間の間隔を小さくできない為、単位体積当り
の伝熱面積が小さく、且つ熱伝達係数も小さい。それ故
、流体に応じたバランスの採れた形状にすることが困難
である為、効率が低下する。この効率の低下と熱伝達係
数不足を補い必要な伝熱面積を採る必要が生じ、形状が
大きくなる欠点がある。In this way, in conventional heat exchangers, heat is exchanged through the tube wall of the thin tube 1°, so the heat transfer area ratio is determined by the ratio of the inner diameter and outer diameter of the thin tube 1°. There is little freedom in selection. Generally, it is not possible to use very thin tubes due to manufacturing reasons,
Furthermore, since the spacing between the thin tubes cannot be made small, the heat transfer area per unit volume is small and the heat transfer coefficient is also small. Therefore, it is difficult to form a well-balanced shape according to the fluid, resulting in a decrease in efficiency. It becomes necessary to take a necessary heat transfer area to compensate for this decrease in efficiency and the lack of a heat transfer coefficient, which has the disadvantage of increasing the size.
そこで本発明は、流体に応じたバランスの採れた形状に
し、単位体積当りの伝熱面積の増加と熱伝達係数の増加
を図って、形状を小さく、特に長さを短くすることをそ
の技術的課題とするものである。Therefore, the present invention aims to create a shape that is well-balanced according to the fluid, increase the heat transfer area per unit volume and increase the heat transfer coefficient, and aims to reduce the shape, especially the length. This is an issue to be addressed.
上記技術的課題を解決するために講じた技術的手段は、
1個又は複数個の貫通穴を通し、この貫通穴の中に、層
状に詰められ且つこの貫通穴の壁面に周辺が密着又は融

導体の板と、この板を挟み密封し前記貫通穴に流体を通
す配管部材からなるように構成することである。The technical measures taken to solve the above technical problems are:
One or more through-holes are passed through the through-hole, and the through-hole is filled with a wire mesh or metal perforated plate, etc., which is packed in a layer and whose periphery is closely attached or fused to the wall surface of the through-hole. A heat conductor plate having a flow path through which a refrigerant such as water or fluorocarbon flows on the outside thereof, and a piping member sandwiching and sealing this plate and allowing fluid to pass through the through hole.
前記技術的手段は次のように作用する。すなわち、流体
が配管部材1の入口から入って金網21が層状に詰めら
れた貫通穴2を通りこの金網21と熱交換し、配管部材
3の出口に出る。この金網21が熱交換した熱は、板状
部材4を介して流路5で冷媒と熱交換する。The technical means works as follows. That is, fluid enters from the inlet of the piping member 1, passes through the through hole 2 filled with wire mesh 21 in layers, exchanges heat with the wire mesh 21, and exits at the outlet of the piping member 3. The heat exchanged by the wire mesh 21 is exchanged with the refrigerant in the flow path 5 via the plate member 4.
以上の如く本発明によれば、次の特有の効果が得られる
。すなわち、流体と熱交換する金網が層状に詰められた
貫通穴単位体積当りの伝熱面積は、線径0.1m、10
0メツシユの金網に対して、従来形の細管内径lin、
細管相互間ピッチ2゜5111flと比較すると、最大
約25倍になり、又熱交換器伝達係数は、相方のヌツセ
ルト数が同じくらいだとすると、約10倍になる。それ
故に、従来形のものより、100から200分の1の大
きさにすることも可能であり、極めて小形で薄板のもの
にできる。更に、金網が層状に詰められた貫通穴が板状
部材に締める割合及び板厚を自由に選定できる為、流体
に応じたバランスの採れた熱交換器が可能になる。As described above, according to the present invention, the following unique effects can be obtained. In other words, the heat transfer area per unit volume of a through-hole filled with layers of wire mesh that exchanges heat with the fluid is 0.1 m in wire diameter, 10
0 mesh wire mesh, conventional thin tube inner diameter lin,
Compared to the pitch between the capillary tubes of 2°5111fl, this is approximately 25 times the maximum, and the heat exchanger transfer coefficient is approximately 10 times as large as the Nutsselt number of the other party. Therefore, it is possible to make it 100 to 200 times smaller than the conventional type, and it can be made into an extremely small and thin plate. Furthermore, since the ratio of the through-holes filled with wire mesh layered to the plate member and the plate thickness can be freely selected, it is possible to create a heat exchanger that is well-balanced depending on the fluid.
