[0002] In recent years, with the increasing integration of electronic devices, the heat dissipation power has multiplied. At the same time, the size and weight of electronic devices are constantly being reduced, making miniaturization and lightweighting increasingly fundamental requirements. Active liquid circulation systems, with their high heat exchange capacity, are being increasingly widely used in the heat dissipation systems of electronic devices.
[0003] However, in practical applications, the limited space on airborne equipment makes it impossible to configure a water-cooled machine.
[0004] Therefore, there is a need to provide a phase change thermal storage tank based on multi-point conduction, which can store the heat emitted by electronic devices through phase change heat absorption, thereby achieving the cooling of electronic devices. Utility Model Content

Detailed Implementation
[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0033] Example 1
[0034] A specific embodiment of this utility model discloses a phase change heat storage tank based on multi-point conduction, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: an upper cover plate 1, a lower bottom plate 3, a drainage pipe 6, an outer cylinder 8, a first coolant connector 5, and a second coolant connector 7. The upper cover plate 1 and the lower bottom plate 3 are fixedly connected to the upper and lower ends of the outer cylinder 8, and the three together form the internal cavity of the heat storage tank.
[0035] Specifically, the upper cover plate 1 is provided with an inlet chamber 2, the lower bottom plate 3 is provided with an outlet chamber 4, and the drainage pipe 6 is vertically arranged between the upper cover plate 1 and the lower bottom plate 3, with the upper and lower ends of the drainage pipe 6 connecting the inlet chamber 2 and the outlet chamber 4.
[0036] Furthermore, a first coolant connector 5 is provided on the outer side of the upper cover plate 1, and the first coolant connector 5 communicates with the inlet chamber 2 inside the upper cover plate 1 for introducing coolant into the inlet chamber 2. A second coolant connector 7 is provided on the outer side of the lower base plate 3, and the second coolant connector 7 communicates with the outlet chamber 4 inside the lower base plate 3 for discharging coolant from the outlet chamber 4.
[0037] Specifically, the first coolant connector 5 is connected to the coolant outlet 202 of the heat dissipation structure through the heat storage tank inlet pipe, thereby enabling the coolant flowing through the coolant channel 203 of the heat dissipation structure to be introduced into the heat storage tank. In other words, the first coolant connector 5 can introduce the high-temperature coolant that has exchanged heat with the heat dissipation structure into the heat storage tank for cooling.
[0038] Specifically, the second coolant connector 7 can introduce coolant into the internal flow channel of the aircraft skin through the heat storage tank outlet pipe.
[0039] Furthermore, the upper cover plate 1 and the lower bottom plate 3 of the heat storage tank are connected as one unit by the outer cylinder 8, and the cavity formed by the three is filled with a phase change medium; in this embodiment, the phase change medium is paraffin wax in a liquid state.
[0040] In this embodiment, as Figure 2 As shown, the drainage tube 6 includes: a heat-conducting drainage tube 61 and a plurality of spherical heat-conducting structures 62 arranged in parallel outside the heat-conducting drainage tube 61.
[0041] Specifically, multiple spherical heat-conducting structures 62 are arranged side by side along the axial direction of the heat-conducting pipe 61; and the multiple spherical heat-conducting structures 62 are distributed at equal intervals on the heat-conducting pipe 61.
[0042] Preferably, the distance between two adjacent spherical heat-conducting structures 62 is smaller than the diameter of the spherical heat-conducting structure 62.
[0043] Specifically, such as Figure 2 As shown, the spherical heat-conducting structure 62 is a spherical shell structure, and the spherical heat-conducting structure 62 is integrally sleeved on the outside of the heat-conducting and flow-guiding pipe 61; and multiple through holes 63 are opened on the spherical heat-conducting structure 62.
[0044] In this embodiment, by providing multiple through holes 63, the inner and outer spaces of the spherical heat-conducting structure 62 can be connected. When a phase change medium is injected into the internal cavity of the heat storage tank, the phase change medium can flow into the interior of the spherical heat-conducting structure 62 through the through holes 63, thereby filling the space between the spherical heat-conducting structure 62 and the heat-conducting pipe 61.
[0045] Preferably, the upper cover plate 1 and the lower bottom plate 3 are both separate structures with the same structural composition.
[0046] Specifically, such as Figure 3 As shown, the upper cover plate 1 has an inlet chamber 2 inside. Multiple first drainage pipe connection holes 9 are arrayed on the bottom plate of the inlet chamber 2. These first drainage pipe connection holes 9 connect the inlet chamber 2 to the internal cavity of the heat storage tank. The upper end of the heat-conducting pipe 61 is fixedly installed in one of the first drainage pipe connection holes 9. Correspondingly, the top plate of the lower base plate 3 has multiple second drainage pipe connection holes, which are used to connect the lower end of the heat-conducting pipe 61 to the outlet chamber 4.
[0047] In practice, the high-temperature coolant, after exchanging heat with the heat dissipation structure, flows into the inlet chamber 2 of the upper cover plate 1 through the first coolant connector 5, and then flows into the heat-conducting guide pipes 61 of multiple guide pipes 6 through multiple first guide pipe holes 9, transferring heat to the guide pipes 6. The heat is then transferred to the phase change medium inside the heat storage tank through the heat-conducting guide pipes 61 and multiple spherical heat-conducting structures 62. The phase change medium absorbs heat and undergoes a phase change, cooling the coolant in the heat-conducting guide pipes 61. Finally, the cooled coolant flows into the outlet chamber 4 and out of the heat storage tank through the second coolant connector 7. Furthermore, after flowing out of the heat storage tank, the coolant can flow into the internal flow channels of the aircraft skin for further cooling.
[0048] In this embodiment, multiple arrayed heat exchange pipes 6 are arranged inside the heat storage tank, and multiple spherical heat-conducting structures 62 are arranged on the heat-conducting heat exchange pipes 61. The multiple spherical heat-conducting structures 62 on the multiple heat exchange pipes 6 form a rectangular cubic lattice heat exchange node, realizing multi-point heat dissipation. When the high-temperature coolant transfers heat to the heat exchange pipes 6, the inner and outer walls of the spherical heat-conducting structures 62 on the heat exchange pipes 6 can quickly conduct the heat to the phase change medium, realizing rapid cooling of the high-temperature coolant by the heat storage tank.
[0049] In this embodiment, by increasing the heat storage capacity of the heat storage tank, the temperature of the coolant flowing into the aircraft skin can be reduced as much as possible, thus weakening the heating effect of the high-temperature coolant on the aircraft skin and avoiding the phenomenon of reduced structural strength of the aircraft skin due to excessive heating.
[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
