この発明は熱交換器に関し、特にヒートパイプ
と固相―液相の相変化をする蓄熱材とを具備した
熱交換器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger, and more particularly to a heat exchanger equipped with a heat pipe and a heat storage material that undergoes a phase change between solid and liquid phases.

に採用している。 A heat pipe transports heat as the latent heat of vaporization of the working liquid sealed inside, and has a thermal conductivity that is tens to hundreds of times higher than that of copper, the metal with the highest thermal conductivity. What you have is
As is well known, heat pipes have conventionally been used in various devices such as heat exchangers by taking advantage of their excellent properties.

度が降下した場合に蓄熱材を熱源として作用させ
るよう構成した熱交換器が提案されている。 By the way, in a normal heat pipe, if there is a temperature difference between the two ends, heat transport will naturally occur, so for example, when cooling any member or part, the temperature of the heat absorbing source that carries away the heat may be caused by some reason. If the temperature rises, the component or part to be cooled will not be able to be cooled or, on the contrary, will be heated. Furthermore, the above situation is the same when heating any member or part; if the temperature of the heat source drops for some reason, the member or part that should be heated cannot be heated, or conversely, it cools down. It becomes a thing. Conventionally, in order to solve the above-mentioned disadvantages, a heat storage material is used, and the heat storage material acts as a heat absorption source when the temperature of the heat absorption source increases, or when the temperature of the heating source decreases, the heat storage material is used. Heat exchangers have been proposed that are configured to act as a heat source.

固相―液相の相変化の際の潜熱を利用した蓄熱材
が好ましいと考えられる。 The heat storage materials used in this type of heat exchanger include those that utilize heat capacity such as water, those that utilize heat storage during phase change between solid phase and liquid phase, or those that utilize latent heat of vaporization. Heat storage materials that utilize heat capacity have a problem in that the heat storage capacity is too small, and heat storage materials that utilize latent heat of vaporization have the problem that the volume change during evaporation is too large, and as a result, during the phase change between solid and liquid phases, It is considered preferable to use a heat storage material that utilizes the latent heat of .

熱材の全量を有効に利用し得ない場合があつた。 Conventionally, calcium chloride hexahydrate (CaCl 2 6H 2 O, melting point 29.92℃, latent heat = 45kcal/Kg ), sodium thiosulfate pentahydrate (Na 2 S 2 O 3 ) 5H 2 O, melting point = 48.2°C) or octadecane (C 18 H 38 , melting point = 28°C, latent heat
58.2kcal/Kg) etc. are known. The ideal behavior of these heat storage materials is to keep the overall temperature constant until the phase change is completed, but in reality, a partial supercooled or superheated state appears,
Not only was it not possible to obtain the initially expected temperature state, but there were also cases in which the entire amount of heat storage material could not be used effectively.

The purpose of this invention is to provide a regenerative heat exchanger that can

FIG. 1 is a schematic diagram showing one example, in which a container 10 is divided into two parts, a high temperature chamber 12 and a low temperature chamber 13, by a partition wall 11. The high-temperature chamber 12 is formed with an inlet 14 and an outlet 15 for flowing a medium to be cooled, such as high-temperature oil, and the low-temperature chamber 1
3 is formed with an inlet 16 and an outlet 17 for flowing a cooling medium such as water. A heat transfer means 18 is provided to penetrate the partition wall 11, and the heat transfer means 18 includes a heat pipe 19.
A heat storage material 20 that undergoes a phase change between a solid phase and a liquid phase is housed in a predetermined container 21 and closely disposed on the outer periphery of the intermediate portion of the
In addition, the heat pipe 19 is configured as a heat flow diode heat pipe that can transport heat only from the high temperature room 12 side to the low temperature room 13 side. As the heat flow diode heat pipe, a steam control type or a liquid flow control type can be used. For example, as shown in FIG.
The valve 22 may be configured to restrict the flow of the gas phase working liquid from the side to the high temperature chamber 12 side.

合は生じない。 However, when using a heat exchanger configured as shown in FIG. 1 to cool insulating oil of power cables, transformers, etc. with cooling water, the insulating oil is flowed into the high temperature chamber 12, and the cooling water is is poured into the cold room 13. Then, the heat possessed by the insulating oil is carried to the cold room 13 side by the heat pipe 19 and transmitted to the cooling water, so that the insulating oil is washed away by the cooling water. In that case, by using a heat storage material 20 that has a melting point lower than the temperature of the insulating oil and higher than the temperature of the cooling water, the insulating oil is cooled while the heat storage material 20 remains solidified. If the cooling water stops or its temperature rises for some reason, the heat of the insulating oil is transferred to the heat storage material 20, and the heat storage material 20 melts while storing the heat, causing the heat storage material 20 to rise to a high temperature. Since the insulating oil is disposed across a room and a cold room, cooling of the insulating oil continues until the heat storage material 20 is completely melted. In addition, in the above heat exchanger, since the heat pipe 19 is a heat flow diode heat pipe, heat does not move in the opposite direction, so even if the temperature inside the cold room 13 rises by mistake, the insulating oil can be heated. No such inconvenience will occur.

上述したと同様な効果を得ることができる。 Note that the above-mentioned action is for an example of cooling insulating oil, but from a different point of view, this also means heating cooling water, so the heat exchanger shown in Figure 1 is used to cool waste heat. It can also be used when heating a predetermined heat medium, such as during recovery. In that case as well, the same effects as described above can be obtained.

ことができる。 Further, according to the present invention, each end of the heat pipe is directly exposed to each of the high temperature room and the low temperature room, so heat exchange is performed directly through the heat pipe, and there is no intervening heat storage material. Therefore, the total thermal resistance during heat exchange is reduced, improving heat exchange efficiency, and at the same time, the heat storage material functions as a buffer, so even if an abnormality occurs in the high temperature source or low temperature source, heating or cooling can be continued for a certain period of time. can be maintained.
