め、熱交換性能が悪くなるという問題があった。[Problems to be Solved by the Invention] Since the conventional condenser is configured as described above, the vapor of the refrigerant (6) exchanges heat with the wall surface of the condensing tube (9) and liquefies, and under zero gravity. As shown in the axial cross-sectional diagram of the cooling pipe in Figure 5, the flow becomes a slag flow containing bubble plugs (10), and a thick liquid film (II) is formed between the wall surface and the steam, resulting in poor heat exchange performance. There was a problem.

目的としている。The present invention has been made to solve the above-mentioned problems, and is intended to prevent the formation of a thick liquid film on a condensing tube mainly used in a zero-gravity environment, and to reduce the liquid film inside the condensing tube as a whole. The aim is to obtain a thin condenser with high heat exchange performance.

て管内の液膜が薄くなり、熱交換性能が大きくなる。[Operation] The liquid tube in the present invention has an inner diameter smaller than that of the condensing tube, so if there is liquid inside the condensing tube, in the weightless environment of space, the surface tension of the liquid causes capillarity inside the liquid tube. Refrigerant liquid flows in with priority. As a result, the refrigerant liquid in the condensing tube is discharged into the liquid tube, and the liquid film inside the condensing tube becomes thinner as a whole, increasing heat exchange performance.
また、同様に凝縮管内の冷媒液体は優先して小流路に流
