Abstract

PURPOSE:To reduce the size of a heat exchanger by a structure wherein through holes are provided on plate members and laminated wire sheets are packed in each through hole and in addition refrigerant passages equipped with fins are arranged in the inner periphery outside the plate member. CONSTITUTION:Through holes 2 are provided on plate members 4. Further, laminated wire sheets 21 are packed in each through hole 2. In addition, refrigerant passages 5 equipped with fins 22 are arranged in the inner periphery outside the plate members 4l. Due to the structure as mentioned above, because the heating surface area per unit volume and the heat transfer coefficient increases, the size, especially the length of a heat exchanger can be reduced.

〔従来技術の問題点とその解析〕[Problems with conventional technology and their analysis]

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.

〔技術的課題〕[Technical issues]

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.

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.

〔本発明によって生じた特有の効果〕[Special effects produced by the present invention]

以上の如く本発明によれば、次の特有の効果が得られる

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.
