Problems solved by technology
[0003] Existing phase change energy storage heat exchangers mostly use partitions to separate the medium, such as patents CN206235227U, CN107747813A, and CN206339141U. The disadvantages of this structural design are: 1. The interface is easy to leak; 2. The device is difficult to process; 3. Energy storage is limited by the size of the device

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0028] A modular phase-change energy storage heat exchanger, including a box body 5, a box cover 3, an interface box 6, an antifreeze liquid infusion pipe 12, and a circulating water delivery pipe 13. The box body is long and has an opening at the top. A gap is formed on one side of the opening of the box body, an interface box is embedded in the gap, and the top of the box body is fastened with a box cover to seal. The phase change material is filled around the circulating water delivery pipe and the antifreeze solution delivery pipe in the tank.
[0029] The interface box is evenly divided into four cavities by cross-shaped partitions 6-5, and the four cavities are respectively the antifreeze liqui...

The invention relates to a module type phase-change energy storage heat exchanger. The space formed around circulating water conveying pipes and antifreezing solution conveying pipes in a box body isfilled with phase change materials. A gap is formed in one side of the opening portion of the box body, and a connector box is embedded into the gap and uniformly divided by a cross-shaped separatingplate into four cavities. The outer side wall of the antifreezing solution inlet cavity communicates with an antifreezing solution inlet pipe connector in a connected mode, and the outer side wall ofthe antifreezing solution outlet cavity communicates with an antifreezing solution outlet pipe connector in a connected mode. The two ends of each antifreezing solution conveying pipe are connected with the antifreezing solution inlet cavity and the antifreezing solution outlet cavity correspondingly. The outer side wall of the circulating water inlet cavity communicates with a circulating water inlet pipe connector in a connected mode, and the outer side wall of the circulating water outlet cavity communicates with a circulating water outlet pipe connector in a connected mode. The two ends ofeach circulating water conveying pipe are connected with the circulating water inlet cavity and the circulating water outlet cavity correspondingly. According to the module type phase-change energy storage heat exchanger, due to the modular battery type design, boxes can be connected in series according to the practical demand of a user, and the heat exchanger is not limited by the inherent stored energy in the using process.
Description
technical field [0001] The invention belongs to the field of heat exchangers, and relates to a phase change heat device, in particular to a modular phase change energy storage heat exchanger. Background technique [0002] The heat exchanger is a closed container equipped with phase-change energy storage materials and two sets of pipelines with different media running through it. The two ends of the antifreeze medium pipeline protrude from both sides of the container and are externally connected to the solar energy. The water inlet and outlet pipes of the heat collector and the two ends of the circulating water pipeline also protrude from both sides of the container and are connected to the heat sink. During the day, the solar thermal collector plate is used to collect heat and transfer it to the phase-change energy storage material in the container, thereby heating up the water in the cooling device for people to keep warm during the day, and the phase-change energy storage ...
