設けられている。2. Description of the Related Art Conventionally, a heat exchanger using a heat exchange medium such as hot water or cold water has been widely used for heating or cooling. This type of heat exchanger has a main body in which a plurality of elongated heat exchange medium passages communicating between an inlet portion and an outlet portion of the heat exchange medium are arranged in parallel via a connecting portion, and has a parallel uneven surface. It is known that a corrugated fin is attached to the main body so that the concave portion is located in contact with the surface of each heat exchange medium passage and the convex portion is located apart from the surface of each coupling portion. In the heat exchanger, the heat exchange medium flowing from the inlet portion flows through the plurality of heat exchange medium passages and flows out from the outlet portion, directly with the surface of the heat exchange medium passage, or through the connecting portion and corrugated fins. The heat is indirectly exchanged with the outside air. That is, when a heat medium such as hot water is used as the heat exchange medium, the outer air is warmed, and when a refrigerant body such as cold water is used, the outer air is cooled so that heat is exchanged by radiation or convection. . The corrugated fins are provided to enhance the heat exchange efficiency.

For example, a temperature sensor such as a thermistor detects the room temperature, and the temperature controller controls the opening / closing valve provided in the heat exchange medium supply pipe to open / close according to the signal. In addition, by using low-priced late-night power, the heat exchange medium is heated by a heating device at night and stored in a heat storage tank (or cooled by a cooling device and stored in a cold storage tank), which is used as a heat exchanger in the daytime. It is also being supplied.

の提供を課題とするものである。However, in the conventional heat exchanger, when the on-off valve of the supply pipe is opened and closed as described above,
The heat radiation (or cooling) action of the heat exchanger changes relatively quickly. That is, since the heat capacity of the heat exchange medium staying in the heat exchanger is generally small, the temperature of the heat exchange medium in the heat exchanger rapidly increases when the supply of the heat exchange medium is stopped by closing the on-off valve. When the heat release (or cooling) action is approached, and the open / close valve is opened to start supplying the heat exchange medium, the temperature of the heat exchange medium in the heat exchanger rises rapidly (when it is the heat medium). Or it descends (when it is a refrigerant body). When the temperature control is performed by the heat exchanger having such characteristics, the on-off valve is opened and closed frequently, which causes a problem that the on-off valve fails and the life is shortened. Furthermore, the temperature change in the heat exchanger is rapid, which is not preferable in terms of life. Further, when the heat exchange medium heated at night by using the midnight power is stored in the heat storage tank, it is necessary to specially install a heat storage tank having a relatively large capacity therefor.
(The same applies when cooling the cooling medium by using midnight power)
Then, this invention makes it a subject to provide the heat exchanger which solves these conventional problems.

And a corrugated fin that is mounted on the main body by disposing the concave portion on the surface position of each heat exchange medium passage and the convex portion on the surface position of each connecting portion.
A plurality of elongated accommodating portions for accommodating the heat storage medium or the refrigerant storage body are provided inside the convex portions of the corrugated fins in contact with the respective connecting portions. In a preferred embodiment of the above heat exchanger, a plurality of accommodating portions are formed by the projections by arranging the plate material having a plurality of parallel elongated recesses in contact with the surface of the heat exchange medium passage. . As a result, the heat transfer coefficient between the housing portion and the connecting portion is improved, and the housing portion can be manufactured with a small amount of material and a good sealing property.

たは放冷作用は緩やかに変化する。As described above, in the heat exchanger of the present invention, a plurality of elongated accommodating portions for accommodating the heat storage medium or the refrigerant storage medium are provided inside the convex portions of the corrugated fins in contact with the connecting portions of the heat exchanger body. Therefore, while the heat exchange medium is being supplied to the heat exchange medium passage to perform heat exchange with the outside air, heat exchange is also performed between the heat exchange medium and the heat storage (or cold storage) medium in the accommodating portion. The temperature of the housing changes according to the temperature of the heat exchange medium passage. Then, when the on-off valve is closed, the action of radiating or releasing the heat from the heat storage (or cold storage) medium in the accommodating portion is continued in cooperation with the heat exchange medium in the heat exchange medium passage, so that the action changes gently. Further, when the on-off valve is opened, the heat exchange action as described above is performed between the heat exchange medium in the heat exchange medium passage and the heat storage (or cold storage) medium in the accommodating portion. The cooling action changes slowly.

い。なお、蓄冷タンクについても同様である。As described above, the change in the heat radiation or cooling effect of the heat exchanger due to the opening / closing of the opening / closing valve becomes gradual, so the opening / closing frequency of the opening / closing valve by the temperature control becomes gradual. Therefore, the life of the on-off valve is extended and the occurrence of failure is reduced. Furthermore, the temperature change inside the heat exchanger becomes gentle. Further, according to the heat exchanger of the present invention, it is possible to heat the heat storage medium in the accommodating section at night by using the midnight power and use it in the daytime, so that the heat storage tank is specially installed as in the conventional case. No need. The same applies to the cold storage tank.
