DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, a high-efficiency phase change heat generator includes a housing 1, a water inlet pipe 2, a water outlet pipe 3, a heat dissipation pipe 4, a heat dissipation plate 5 and a phase change material filler 6.

[0024] like Figure 1 , Figure 2 As shown, the box body 1 is arranged in a rectangular shape, the water inlet pipe 2 and the water outlet pipe 3 are arranged at the upper and lower ends of the box body 1, the heat dissipation pipe 4 is arranged in the box body 1 and connects the water inlet pipe 2 and the water outlet pipe 3, and the heat dissipation plate 5 is multi-layered and is arranged on the outer wall of the heat dissipation pipe 4 at intervals.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the phase change material filler 6 is sleeved on the outer wall of the heat pipe 4 and is located between two adjacent heat sinks 5. The upper and lower end surfaces of the heat sink 5 are both provided with serpentine heat conducting strips 51, and the surface of the phase change material filler 6 is provided with heat conducting grooves 61 for the heat conducting strips 51 to be embedded.

[0026] During the heat storage process, hot water passes through the heat pipe 4 and transfers heat to the heat sink 5, and then the heat sink 5 introduces heat into the phase change material filler 6. At the same time, since the heat sink 5 has a heat conductive strip 51, and the heat conductive strip 51 is embedded in the phase change material filler 6, the contact area between the heat sink 5 and the phase change material filler 6 can be increased, and the heat can be fully introduced into the phase change material filler 6, and the heat is stored to complete the heat storage process. The energy release process is the opposite, which will not be described in detail.

[0027] Therefore, by providing a heat sink 5 covering the heat pipe 4 and a phase change material filler 6, and increasing the flow time and flow path of the water source in the heat pipe 4, it is ensured that the water source can fully introduce heat into the phase change material filler 6 or fully absorb heat from the phase change material filler 6, thereby achieving sufficient energy storage and release, reducing energy consumption efficiency and loss, and reducing resource waste.

[0028] like Figure 4As shown, the upper end surface and the lower end surface of the heat dissipation plate 5 are both provided with a clamping block 52 , and the surface of the phase change material filler 6 is provided with a clamping groove 62 for the clamping block 52 to be embedded.

[0029] Therefore, during the assembly process of the heat sink 5 and the phase change material filler 6, the heat sink 5 and the phase change material filler 6 are quickly and accurately fixed by the snap-fit ​​cooperation between the clamping block 52 and the clamping slot 62, thereby increasing the stability of the connection process between the two and improving the assembly efficiency.

[0030] like Figure 2 As shown, a plurality of heat dissipation pipes 4 are arranged side by side and arranged in a serpentine shape, so as to increase the storage capacity of the water source and fully realize energy storage and energy release. Two adjacent heat dissipation pipes 4 are arranged in a staggered shape, so as to fully transfer heat to the heat dissipation plate 5, or fully absorb heat from the heat dissipation plate 5 into the heat dissipation pipe 4, so as to improve the effect of energy storage and energy release.

[0031] like Figure 2 , Figure 5 As shown, the heat dissipation pipe 4 includes a plurality of straight pipes 41 and a plurality of elbows 42 connecting the straight pipes 41 , bamboo joint inserts 43 are provided at both ends of the elbows 42 , and bamboo joint insert holes 44 for inserting the bamboo joint inserts 43 are provided at both ends of the straight pipes 41 .

[0032] Since the heat sink 5 and the phase change material filler 6 are all set and fixed in the heat sink 4, a split heat sink 4 is set up, and the straight tube 41 is first passed through the heat sink 5 and the phase change material filler 6 to achieve the connection between the heat sink 4 and the heat sink 5 and the phase change material filler 6, and then the bamboo joint plug 43 on the elbow 42 is quickly inserted into the bamboo joint hole 44 on the straight tube 41 to achieve rapid assembly of the heat sink 4, the heat sink 5 and the phase change material filler 6, thereby achieving rapid and convenient assembly of the entire phase change heat sink, thereby ensuring rapid production of the phase change heat sink.

[0033] like Figure 2 As shown, mounting plates 7 are horizontally arranged at both ends of the heat dissipation pipe 4, and both sides of the mounting plate 7 are bent upward to form support plates 71 that fit the inner wall of the box body 1, and the support plates 71 are fixed to the box body 1 by screws. This can achieve stable fixation of the heat dissipation pipe 4 and stable support of the heat dissipation pipe 4, thereby increasing stability during operation.

[0034] like Figure 2 As shown, both ends of the mounting plate 7 are bent downward to form positioning plates 72, and both inner walls of the box body 1 are vertically provided with angle steels 73 that abut against the positioning plates 72. Therefore, by providing the positioning plates 72 and the angle steels 73 to cooperate with each other, the heat dissipation pipe 4 is stably supported, the impact resistance of the entire phase change heat exchanger is increased, and the stability and safety of the phase change heat exchanger during operation are ensured.

[0035] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
