In order to reuse unutilized energy (hereinafter referred to as "industrial waste heat") that is discarded after energy consumption, equipment for storing and transferring thermal energy is required.

In the past, the method of utilizing industrial waste heat was mainly used to supply heat by directly connecting pipes of industrial waste heat generated at an industrial site.

However, the method of supplying heat through the pipe requires a separate piping equipment, is disadvantageous for long distance transportation, and because the pipe must be equipped with a separate insulation for the efficiency and effectiveness of industrial waste heat recycling was not great.

Therefore, recently, a method of storing industrial waste heat in a heat storage tank and transporting it to a demanding place that requires heat (hereinafter, referred to as a "transport heat storage method") is used.

Transport type heat storage system can modularize the heat storage tank equipped with the facility to store heat, compared to the way of supplying heat through the pipe, it is possible to control the heat storage capacity as needed, no separate piping, etc., It has the advantage of being advantageous for long distance transportation.

Korean Patent Laid-Open No. 10-2015-0081739 discloses a transport type heat storage system. Specifically, the present invention discloses a transport type heat storage system capable of storing heat in a latent heat storage material built into a container using fruit oil, mounting the container on a vehicle, and moving from a source of industrial waste heat to a demand destination.

However, this type of transportation heat storage system has a disadvantage that the heat storage process is performed only by the fruit oil, and the heat storage efficiency may be reduced because the circulation of the fruit oil in the container cannot be diversified.

Japanese Laid-Open Patent Publication No. 2009-97746 discloses a heat storage device. Specifically, a heat storage device capable of increasing the contact area between heat storage means and heat transfer wall while improving the pressure resistance performance of the heat transfer wall and improving heat exchange performance is disclosed.

However, this type of heat storage device considers only heat transfer by conduction between the heat storage means and the heat transfer wall, and therefore, there is a limit in improving the heat storage efficiency.
