生する。Next, the operation will be described. When the evaporator main body is heated, vapor is generated from the outer periphery of the wick because the liquid in the liquid reservoir penetrates into the wick inside the evaporator main body by the capillary phenomenon. This vapor is condensed by flowing from the vapor pipe toward the condenser through the vapor flow path between the evaporator body and the wick, and the condensed cooling liquid is condensed from the liquid pipe to the liquid reservoir inside the wick. Returned to the department. The cooling liquid that has returned to the liquid reservoir penetrates into the wick by a capillary phenomenon, so that steam is continuously generated from the outer circumference of the wick.

あった。Since the conventional loop-type heat pipe evaporator is constructed as described above, it has a single-tube construction for returning the cooling liquid condensed in the condenser to the liquid reservoir inside the wick. The liquid pipe is not insulated at all in the state exposed to the vapor flow path between the evaporator body and the wick, therefore, by heating the liquid pipe by the steam flowing through the vapor flow path, There was a problem that the temperature of the liquid returning from the liquid pipe to the liquid reservoir inside the wick becomes high. That is, when the temperature of the liquid returning to the liquid reservoir inside the wick becomes high, the liquid temperature of the liquid reservoir rises due to the high temperature liquid, and the temperature of the steam generated from the outer periphery of the wick also rises accordingly. There is a problem that the temperature of the entire loop heat pipe system rises and exceeds the allowable temperature of the heat generating device to be cooled by the evaporator of the loop heat pipe.

An object of the present invention is to obtain a loop heat pipe evaporator which can prevent heating and keep the temperature of the whole loop heat pipe system low.

まり液を低温に保つことができる。Next, the operation will be described. Evaporator body 1
The liquid in the liquid reservoir 3 has penetrated into the wick 2 inside by a capillary phenomenon, and when the evaporator main body 1 in this state is heated by the heat radiation from the heat generating device, the heat is generated by the inner circumference of the evaporator main body 1. It is transmitted to the wick 2 from the joint between the surface and the protrusion 2 c of the wick 2. As a result, the liquid in the wick 2 and the liquid reservoir 3 is heated, so that steam is emitted from the outer peripheral surface of the wick 2. This steam passes through the steam flow path 4 and the steam pipe 5
To a condenser (not shown) from which it is condensed. Thus, the condensed cooling liquid is returned from the liquid pipe 6 to the liquid reservoir 3. At this time, the liquid pipe 6 that crosses the vapor flow path 4 between the end wall at one axial end of the evaporator body 1 and the wick end plate 2a is covered with the sleeve 7, and the liquid pipe 6 and the sleeve 7 are separated from each other. A heat insulating space 8 is formed between them, and this heat insulating space 8 serves as a vacuum heat insulating space especially in space, so that the liquid pipe 6 is not heated by the steam flowing through the steam flow path 4. Therefore, the cooling liquid returning from the liquid pipe 6 to the liquid reservoir 3 is not heated by the vapor in the evaporator body 1 to be heated to a high temperature, and the returning cooling liquid cools the pooled liquid in the liquid reservoir 3 to a low temperature. Can be kept at

保つことができるという効果がある。According to the first embodiment explained above, the liquid pipe 6 for returning the cooling from the condenser to the liquid reservoir 3 in the wick 2 is vaporized across the vapor flow path 4 in the evaporator body 1. Since the contact region is covered with the sleeve 7 and the heat insulating space 8 is formed between the sleeve 7 and the liquid pipe 6, the liquid pipe 6 is heated by the steam flowing through the steam flow path 4. Therefore, it is possible to prevent the temperature of the pooled liquid in the pooled liquid 3 from rising due to the liquid returned from the liquid pipe 6 to the pooled liquid 3 and to cool the pooled liquid to a low temperature. Therefore, there is an effect that the entire loop heat pipe system can be kept at a low temperature.

Therefore, the same parts as those in FIG. In the figure, 10 is a heat insulating member wound around the vapor contact portion of the liquid pipe 6, and a metal member having a relatively low thermal conductivity such as titanium or stainless steel is mainly used, but the thermal conductivity is relatively low. A non-metal member can also be applied as long as it is a member. That is, in the second embodiment, the heat insulating member 10 which replaces the sleeve 7 of the first embodiment is wound around the vapor contact portion of the liquid pipe 6. Therefore, also in the case of the second embodiment, the same effect as that of the first embodiment can be obtained.

The liquid returned to the reservoir does not raise the temperature of the pooled liquid in the pool, and the pooled liquid can be kept at a low temperature. Therefore, the entire loop heat pipe system should be kept at a low temperature. There is an effect that can be.
