MODULAR PHASE CHANGE ENERGY STORAGE HEAT EXCHANGER

The disclosure relates to a modular phase change energy storage heat exchanger. A phase change material is filled around circulating water delivery pipes and anti-freezing fluid delivery pipes in a tank; a notch is formed in the opening side of the tank; an interface box is embedded in the notch; the interface box is uniformly divided into four cavities by a cross-shaped baffle plate; the outer side wall of an anti-freezing fluid inlet cavity is communicated and connected with an anti-freezing fluid inlet pipe interface; the outer side wall of an anti-freezing fluid outlet cavity is communicated and connected with an anti-freezing fluid outlet pipe interface; two ends of two anti-freezing fluid delivery pipes are respectively connected with the anti-freezing fluid inlet cavity and the anti-freezing fluid outlet cavity; the outer side wall of a circulating water inlet cavity is communicated and connected with a circulating water inlet pipe interface; the outer side wall of a circulating water outlet cavity is communicated and connected with a circulating water outlet pipe interface; two ends of two circulating water delivery pipes are respectively connected with the circulating water inlet cavity and the circulating water outlet cavity. For the modularized "battery type" design of this heat exchanger, tanks are connected in series according to practical demand of a user, and use is not limited by its inherent energy. 6-1 6-2 6-5 6-6 69 6-7
