AI Technical Summary
Technical Problem
Existing brazed plate heat exchangers cannot store thermal energy, which means that external energy storage systems are needed in intermittent heat source or fluctuating load scenarios, increasing system complexity and cost.
Method used
The heat storage plate encapsulated by PCM is integrated into the heat exchanger as a plate, and the passages on both sides of the plate are divided into heat storage channels and heat release channels, which are separated from the cold fluid passages and hot fluid passages of the existing heat exchanger. The opening and closing are achieved through the end pipe mechanism.
Benefits of technology
Reduce peak loads, improve system flexibility and stability, reduce the need for additional tanks or equipment, and save space and costs.

Abstract
The utility model discloses a brazing plate heat exchanger of energy storage, relates to brazing plate heat exchanger technical field. The utility model discloses a heat exchanger body, four end pipe mechanisms and a plurality of heat storage plates, and the heat exchanger body includes the front end plate, a plurality of plate piece groups and rear end plate that arrange in turn layer by layer, and a plurality of plate piece groups form a plurality of alternatingly arranged hot fluid passageway and cold fluid passageway in the heat exchanger body, and the plate piece group is composed of first plate piece and second plate piece. The utility model discloses the heat storage plate of PCM encapsulation as the plate piece of plate piece group is integrated in the heat exchanger, and the passway of heat storage plate both sides divides out heat storage passageway and heat release passageway, and the cold fluid passageway and hot fluid passageway in the existing heat exchanger are disconnected, and are opened and closed through the end pipe mechanism, realize energy storage and energy release, can reduce peak load, improve system flexibility and stability, reduce fluctuation appearance, need not additional storage tank or equipment, save space and cost.
