本発明はヒートパイプ係り、特に人工＃星等に最適な温
度制御用ヒートパイプに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a heat pipe, and particularly to a heat pipe for temperature control that is optimal for artificial stars and the like.
人工衛星の熱制御は、従来コーテイング材の選択や断熱
材の使用などで搭載・電子機器等の温度を許容値内に制
御するいわゆる受動式熱制御方式が採用されてきたが、
この方式ではその熱料ｔｆｖａｔ４＠力に限界がある。Thermal control of artificial satellites has traditionally been based on the so-called passive thermal control method, which controls the temperature of onboard electronic equipment within an acceptable range by selecting coating materials and using insulation materials.
In this method, there is a limit to the heating power tfvat4@.
一方、衛星の三軸姿勢制御化に＃−なう消費成力の大容
敏化や、信頼度の向上のための搭載機４の要求瀘度保持

が求められるようになった。On the other hand, in order to cope with the increase in power consumption due to three-axis attitude control of the satellite and the narrowing of the required stability range of the onboard aircraft 4 to improve reliability, further High and low heat control functions are now required.

加熱部のＩＭ Ｉｆを一定に保つこと、ができろ。In response to the above requirements, the Gas Heat Quiz was developed as an active thermal control element for space use. This is done by filling the end of the condensing section with a certain amount of non-condensable gas, so that the condensation of the refrigerant does not become stale, and the conductance of the heat pipe is changed to i=r. In this way, the heat pipe not only conveys the heat input given from the heating section to the heat dissipation section, but also adjusts to fluctuations in heat input and changes in trajectory conditions, and increases the effective number of heat sections. change,
It should be possible to keep the IM If of the heating section constant.
しかしながら、この方式では、（１）ガスだめをもつな
どのヒートパイプの構造が複雑になり、製造技術の高度

部から制御できない、などの欠点をもつ。However, with this method, (1) the structure of the heat pipe becomes complicated, such as having a gas reservoir, and sophisticated manufacturing technology is required; and (2) the responsiveness of the heat pipe cannot be controlled externally. It has the following drawbacks.

ヒートパイプを提供することを□目的とする。The object of this invention is to provide a heat pipe for temperature control N which has a simple structure and whose capacity can be easily controlled from the outside, avoiding the complication of the structure as described above.
本発明を実施例に基づいて説明する。第１図は本発明の
実施例である。The present invention will be explained based on examples. FIG. 1 shows an embodiment of the invention.

にならないよつに補助ヒーター６で放熱側を加熱する。When it is necessary to radiate the heat of the heating element 1 to the outside, the heat is transmitted to the υ heat radiating plate 5 by the heat pipe 4 which is connected to the wick 2 and the refrigerant 3, and is radiated to the outside. In the first step, the necessary amount of heat is added from the auxiliary heater 6 to the heat radiation side. This necessary amount is because the heat dissipation side is originally exposed to the absolute zero temperature in outer space, so the refrigerant 3 is solidified. Second, when there is no need to dissipate heat, the auxiliary heater 6 is not activated, and the heat pipe is not activated, so there is very little heat transfer. In the opposite case, the auxiliary heater 6 heats the heat radiation side so that the temperature does not drop below the melting point of the refrigerant.

でも応用できる。At this time, the input to the auxiliary heater 6 is determined based on whether there is a necessity for heat radiation based on the temperature of the heating element and whether the degree of cooling on the heat radiation side is below the melting point of the refrigerant. This judgment can be applied to thermal switches using bimetals or simple microcontrollers.

A razor-shaped heat pipe can be configured by simple external operation. In addition, the power supply for the auxiliary heater consumes very little acid power, and a heat pipe with a simple structure that is inexpensive can be provided.

を行う。The heat generated from the heating element 1 inside the sanitary is transferred to a heat sink 5 by a heat pipe 4 composed of a wick 2 and a refrigerant 3.
The heat is then radiated into space. However, since the heat radiation side is exposed to a space of absolute zero temperature, the refrigerant 3 on the heat radiation side is often solidified. Therefore, when there is no need to dissipate the heat generated inside the satellite, the heat pipe 4 is not activated by using the above condition, and when heat dissipation is necessary, the auxiliary heater 6 (heat pipe By heating the heat dissipation side of 4, the temperature of the heat dissipation side does not go below the freezing point temperature of the refrigerant 3.The input of the auxiliary heater 6 is whether or not heat dissipation is necessary, and whether the heat dissipation side is Depending on whether the temperature is below the melting point of the refrigerant 3, control is performed using a microcomputer or a bimetal heat switch.
