Embodiment 1

[0036] refer to figure 1 , in this embodiment, the phase change heat storage unit includes a container 1, which is a cylindrical tube, and a heat exchanger is arranged in the container 1.

[0037] Such as figure 1 As shown, the heat exchanger includes an inlet 21 and an outlet 22. The inlet 21 is connected to an input pipe 23, and the outlet 22 is connected to an output pipe 24. There are three output pipes 24, which are connected and merged at the outlet 22.

[0038] In this embodiment, the input pipe 23 is a spiral coil, and the output pipe 24 can be arranged outside the spiral coil, or arranged in the coil of the spiral coil. The output pipe 24 is configured as a corrugated pipe.

[0039] After simplifying the spiral coil input pipe 23, the structure of the heat exchanger in this embodiment is as follows: image 3 shown.

[0040] The gap between the heat exchanger and the container is filled with a phase change heat storage material, taking paraffin / graphite composite p...

Embodiment 2

[0047] refer to Figure 4 , in this embodiment, the phase change heat storage unit is set with double heat exchangers, each heat exchanger exists independently, the first heat exchanger input pipe 231 is connected to the first heat exchanger inlet 211, and the first heat exchanger The output pipe 241 is connected to the inlet and outlet 221 of the first heat exchanger; the input pipe 232 of the second heat exchanger is connected to the inlet 212 of the second heat exchanger, and the output pipe 242 of the second heat exchanger is connected to the inlet and outlet 222 of the second heat exchanger.

[0048] The number of input pipes of the first heat exchanger and the second heat exchanger can be the same or different, such as Figure 4 As shown, there are two output pipes 241 of the first heat exchanger, and one output pipe 242 of the second heat exchanger, but as required, there may be one, two, three or more.

[0049] In this embodiment, both the input pipe 231 of the first ...

Abstract

The invention provides a phase-change heat accumulation unit comprising a container and at least one heat exchanger positioned in the container. Phase-change heat accumulation materials are filled among the heat exchangers and the container wall, each heat exchanger comprises an input tube and an output tube, and the input tube is a spiral coil. By the design, modular design of phase-change heat accumulation equipment is realized, a certain quantity of the phase-change heat accumulation equipment can be mounted as required, various heat exchangers can be designed according to types of heat resources, and the phase-change heat accumulation unit is applicable to different heat resources.

Description

Technical field [0001] The present invention involves a heat storage device, especially a phase -changing heat storage unit that is convenient for installation. Background technique [0002] Energy is the basis for human beings to survive and develop. With the rapid development of global industries, global stone fuel has continued to decrease, and the problem of energy shortage and environmental pollution has become a common problem facing countries around the world.And develop renewable energy has become an important issue facing human beings. [0003] Thermal storage technology is an important technology to improve energy utilization efficiency and protect the environment. It has broad application prospects in the fields of solar heat utilization, power migration, industrial waste heat recycling, and civil and military fields.There are generally two types of heat storage methods. One is the method of showing heat storage and heat storage. Using the temperature of the object to ...
