The present invention relates to a PCM-applied plate heat exchanger, and more particularly, to a PCM-applied plate heat exchanger capable of recovering energy by performing waste heat exchange with phase change materials to recover waste heat to be used as useful energy. .

With the high efficiency of fossil fuel-using energy conversion devices directly related to the suppression of global warming, interest in waste heat is increasing. As a typical waste heat, there is so-called industrial waste heat emitted from consumption of industrial energy, which occupies about 45% of the total domestic energy.

Industrial energy is used in various fields such as agriculture, industry, fisheries, forestry, and mining, so the amount of waste heat emitted is considerable.

However, since industrial waste heat occurs in industrial processes and has temporal fluctuations in energy, the usefulness of waste heat decreases.

A general multi-tube or plate-type heat exchanger is designed to exchange heat between a hot fluid and a cold fluid. For this reason, in order to exchange heat between two or more types of fluids, an additional heat exchanger must be installed, and since it is a structure that is connected and installed, it is difficult to install due to an increase in size and there is a problem of deterioration in efficiency due to energy loss.

The following is the prior patent technology related to the heat exchanger.

However, the prior art has a problem in that two types of heat medium exchange heat with each other, and in order to exchange heat between two or more fluids, there is a problem that an additional heat exchanger must be installed, and the heat medium located close to the cylindrical portion has a large heat loss. There is a problem.

② Registered Patent No. 10-1183546 (multi-tube heat exchanger) has a body for supplying and discharging water, a combustion unit installed under the body, an electric heating unit having recessed grooves and protruding grooves, and a top of the body It is installed in the combustion gas discharge unit for guiding the combustion gas discharged from the heat transfer portion to the outside of the body.

The prior art is made of a multi-tube type and was intended to increase the heat exchange efficiency with the recessed groove and the protruding groove. However, since the heat exchange fluid is a heat exchange method between water and combustion gas applied to a boiler, heat exchange between other fluids is There is an impossible problem.

③ Registered Patent No. 10-0954439 (Multi-effect plate type heat exchanger) includes a first inlet and a first outlet and a first heat exchange medium that allow a first heat exchange medium to flow in at one end and move in the longitudinal direction to be discharged to the other end. A plurality of first heat transfer plates for puncturing the first auxiliary inlet through which the first supplemental water to be mixed flows; The first heat exchange medium and the second heat exchange medium having the opposite inlet / outlet direction, are mixed with a second inlet and a second outlet and a second heat exchange medium to be introduced from one end and moved in the longitudinal direction to be discharged to the other end. 2, a plurality of second heat transfer plates that perforate the second auxiliary inlet for introducing the replenishment water; and the plurality of first heat transfer plates and the second heat transfer plates form an alternating relationship with each other. Multi-effect plate heat exchanger, characterized by.

In the prior art, the first heat exchange medium and the first replenishment water are different from each other in temperature, and therefore, the three types of heat exchange medium cannot be regarded as heat exchange. In addition, the prior art is a plate heat exchanger, not a cylindrical heat exchanger, and is a structure in which one type of fluid flows for each layer. As the number of types of fluid increases, the structure becomes complicated and heat exchange is not properly performed.
