Abstract

PURPOSE:To enable a stable heat transfer operation by filling low boiling fluid and non-condensing gas for determining the boiling temperature of said low boiling fluid at the inside of a vessel of closed circuit having a heating part and a cooling part, and unidirectional valve is provided at the part of a down pipe. CONSTITUTION:Low boiling fluid 2 and non-condensing gas 3 for determining the boiling temperature of said low boiling fluid are filled at the inside of the vessel 1 of closed circuit having the heating part 5 and the cooling part 6. In this heat transfer device, unidirectional valve 8 is provided at the part of the down pipe 7 which communicates to the one side of the cooling part 6. Bubbles which generate at this time, ascend only along another pipe 9, and do not ascend along the valve 8, and the flow is determined in one direction. Hereby, the stable heat transfer operation can be performed.

【発明の詳細な説明】 〔発明の利用分野〕 本発明は熱伝達装置に関する。[Detailed description of the invention] [Field of application of the invention] The present invention relates to heat transfer devices.

伝熱量。The conventional heat transfer device has a closed container 1 as shown in FIG.
A low boiling point liquid 2 is sealed inside the chamber, and the heat transfer characteristics at this time are as shown in FIG. 4, where the amount of heat transfer increases in proportion to the rise in temperature. Furthermore, in a heat transfer device 4 (for example, Japanese Patent Publication No. 57-23194) which has a self-temperature control property by enclosing a non-condensable gas 3 together with a low boiling point liquid as shown in FIG.

が不安定であるという欠点があった。As shown in FIG. 6, it is known that the gas has a thermal switching effect in which heat transfer starts at the boiling temperature determined by the sealing pressure. However, if the container forms a closed circuit (not shown) with a rising pipe and a descending pipe, the bubbles will rise at the same time at the start of boiling, and the flow direction will not be determined and the flow will be oscillating. The disadvantage was that the heat transfer properties were unstable.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、これらの欠点を除いた安定な伝熱作用
を行なう装置を提供することにある。An object of the present invention is to provide a device that eliminates these drawbacks and performs a stable heat transfer function.

〔発明の概要〕[Summary of the invention]

験的にわかったので、一方の上昇流を抑制すればよい。That is, in the present invention, it has been experimentally shown that the reason why the flow becomes oscillatory is because the bubbles generated by boiling rise in both of the connecting pipes, and a bubble pump action is performed in both cases. Now that we understand, all we have to do is suppress the upward flow on one side.

〔発明の実施例〕[Embodiments of the invention]

決ぬれられる。An embodiment of the present invention will be described below with reference to FIG. One pipe 7 (for example, a downcomer pipe) connecting the heating section 5 and the cooling section 6
A device 8 (for example, a check valve) that allows flow to flow in only one direction is installed in the middle of the flow. The bubbles generated at this time rise only in the other pipe and do not rise to the device 8 side, and the flow is determined in one direction.
